Chaozhou: What is the solution to the "pain of passing" in the train bridge and Handong?

As one of the important parts of highway engineering, Handong plays a role in quickly eliminating the surface water along the road to ensure the safety of the roadbed. Ensure that the drainage system in the culvert is unblocked and has a significant impact on urban traffic conditions. The culverts that accumulate water when they encounter heavy rain have brought a lot of inconvenience to the past people and surrounding residents, and there are also great hidden safety hazards. Earlier this month, the reader's "Public Opinion Direct Train" on the full media of the Chaozhou Daily reflected that Fengxi Zhennan South Road Train Bridge Cave and Zhanhong Road Train Bridge Cave often accumulated water during the rainy period, which caused the cave to not be opened to traffic. It has brought great inconvenience with the surrounding shops and residents ...

In this issue of public opinion, focusing on the problem of water and bridge caves of Zhenchao South Road and Hanghong Road Hashicon Cave. How serious is these two culverts? What are the reasons for the water accumulation? What do nearby citizens and past drivers feel about this? What governance measures do relevant departments take? How to effectively improve the phenomenon of stagnant water when heavily rains? In response, the reporter visited the investigation many times and interviewed the city management department, the traffic police department, and the representatives of the Municipal People's Congress to explore the solution.

Playback on the spot

Bridge stubborn water stubborn pedestrian vehicles cannot pass through

On the morning of March 23 this year, after a heavy rain, Fengxi Zhenchao South Road Train Qiaodong sewage was infused, and the water accumulated was serious. Due to the unfamiliar road conditions, the driver of a car turned off after wading, and the two were trapped in the car. At more than 10 am on the same day, the reporter saw at the scene that half of the wading vehicle was soaked in the water. At 11:52, the wading vehicle was successfully dragged away from the scene. The sides of the soaked road section are pulled up again, and the vehicle is prohibited from passing the vehicle.

On the evening of July 2nd, the rain poured a whole night. At 11:48 on July 3rd, when the reporter came to Fengxi District Zhanhong Road Train Bridge Cave, the reporter found that the water accumulation was very serious. Except for the flooding of the pavement surface, the channels on both sides of the pavement were not spared. The reporter observed that there were a lot of water accumulated in the channels and houses on both sides of the pavement. The relevant departments have pulled the alert slogan in front of Handong, reminding the past to regulate traffic control in accordance with the storage of water, and the owner is bimmeated into the heart of the heart. Under the alert sign, there is also a drainage responsibility sign, which states the name of the accumulated water point, the responsible person and the contact number. At the scene, in addition to the alert reminder set up by the relevant departments, some people were placed in the trash can in the middle of the road to remind passenger vehicles not to pass the bridge culvert. During the interview, vehicles continued to come and have to return or bypass the original road after seeing the water accumulation.

There is a large amount of water in the culvert. Subsequently, the reporter came to the train bridge Dongdong Cave of Zhenchao South Road, Fengxi District, and found that the culvert after the heavy rain was also a piece of ocean. The alert slogan "Bridge Handling Water Transportation Control Casters for Destructability" was soaked in the water. The word "Bridge Hydrotomy Vehicle Forbidden".

On the afternoon of July 5th, the sky was raining again. The reporter came to Fengxi Zhanhong Road Train Qiaodong Cave again, and found that Han Dong still had severe water accumulation. Later, the reporter came to the train Qiaodong on Zhenchao South Road and found that there were a large amount of water accumulated in the culvert, and a large amount of garbage floated on the stagnant water, and the culvert environment was dirty. Due to the serious accumulation of water, these two culverts have been implemented, and vehicles are prohibited from passing vehicles.

Some time ago, there were many rainfall weather in our city, and the stagnant water accumulated in the city was more common. In the past, the people hoped that the relevant departments would try to properly solve such problems.

A heavy rain made Zhanhong Road Handong's water accumulation serious.

Citizen voice

Hangong deposits are difficult to solve by the people who are difficult to travel

What impact does Handong accumulation have on the past and local residents? The reporter interviewed nearby merchants, residents, and past people to listen to their voice.

Ms. Shi, who lives in the auspicious home near Fengxi Zhanhong Road, said: "Every heavy rain, this culvert is serious and cannot be passed. Usually I only take 5 minutes home from the unit through the unit. You must bypass it, and the journey becomes about 15 minutes. My sister lives in Changmei Village, Fengxi, and the location of the work is near this culvert. Handong is the only way for her to work. Once Handong cannot pass, she often has to go around half a few times. Only the way to work can reach the work place. Every time the rain, my sister has to ask me, whether Han Dong can live, if she can't go, she has to detour in advance. This brings a lot of inconvenience to our lives. "

Ms. Huang, a department store near a department store near Zhenchao South Road, Fengchao South Road, said that every time the road is raining, it cannot pass. The traffic is inconvenient, and her business is not easy to do. Whenever water accumulation, the garbage around the culvert is brought to the culvert, and the sanitary environment is also poor. Previously, the relevant departments had repaired the culvert, but failed to solve the problem. It is hoped that the relevant departments can find ways to solve the phenomenon of water accumulation and the problem of garbage floating as soon as possible.

In the past, Mr. Wang, a truck driver, said, "When you mention these two culverts, I have a bitter water. There are many factories in this area. There are many trucks here to pull the goods. After that, we have to go around the distance. While the road is detour, the traffic of other sections will be increased. The phenomenon of traffic jams often occurs. Handicapped water is not only inconvenient to travel, but also hidden safety hazards. Often passing through the wading. After driving into the culvert, the car often turns off or is drowned, which threatens the personal safety of the past personnel. "

Cause analysis

Low -lying rainwater inverted irrigation to exacerbate culverts with water

The reporter learned from the Fengxi District Comprehensive Administrative Law Enforcement Bureau that the Guangmeishan Railway across Fengxi District Zhanhong Road and Zhenchao South Road, and both roads were built with train bridge culverts. These two train bridge Hanyu has existed since the construction of the Guangmeishan Railway. At the beginning, because the enterprises in the railway station have not yet formed scale, the enterprise's displacement is not large, and the water accumulation problem of culverts is not prominent. Later, with the development of economic and social development, enterprises in the railway station area developed rapidly, factories were linked, and culvert drainage facilities were far from meeting the demand for emissions. The Management Committee of the Fengxi District Party Committee attaches great importance to this, and has repeatedly transformed and dredging the drainage pipe network in the north district of the train station, including Zhanhong Road and Zhenchao South Road. In March 2020, Fengxi District launched the "Fengxi District Zhanhong Road, Zhenchao South Road Train Bridge Chan Drainage System and Road Reconstruction Project", and once again renovated and upgraded the drainage system of the two train bridge culverts. The content of the project includes re -buried the road rainwater pipe, replacing large flow drainage pumps, adding train bridges culverts and rainwater pressure pipes; repairing damaged concrete pavements, and laid asphalt concrete pavement; re -installed road edge stones, laid street lanes, supporting street lights, tree ponds, tree ponds Greening, and simultaneously buried weak power communication pipelines. After the transformation, the water pump pumping capacity of Zhenchao South Road can reach 900m3/h. Zhanhong Road rainwater pump pumping capacity can reach 800m3/h, which greatly improves the drainage capacity of the two train bridge culverts.

After the completion of Fengxi District Zhanhong Road, Zhenchao South Road Citrus Drainage System and Road Reconstruction Project, it effectively improved the ability and level of prevention and waterlogging in this area, and alleviated the problem of water immersion. However, due to the special nature of the two train bridges and culverts and the defects of the design of railway bridge culverts, the rainwater of the road around the area around the culvert around the area around the cave will quickly bring together to the train bridge culvert to cause water accumulation. Because the stagnant water of the two culverts is discharged into the Laoxi Creek, the heavy rain strikes, and the water level of Lao Xixi rises higher than the bottom of the drainage pipe to form a top support. Water situation will be more serious. In addition, the position of the two sewage wells on the two sewage wells in Zhenchao South Road is relatively low. During the heavy precipitation process, it is also easy to cause culverts to deposit water due to sewage pouring.

The relevant person in charge of Fengxi District Comprehensive Administrative Law Enforcement Bureau said that since the bureau's intervention in the management of the train Qiaodong in February this year, the bureau has effectively strengthened the on -site inspections and emergency duty. Actively strive for management funds, strengthen management through entrustment, implement special personnel, and do a good job of daily maintenance of water pumping equipment and facilities, and dredging of drainage pipeline networks. In order to do a good job of on -site safety protection, the bureau also added a gate and a warning sign to the two culverts, reminding passenger vehicles to encounter a water -stained water detour. In addition, strengthen the cooperation and linkage of the department, formulate the "Floating Plan for the Railway Bridge Courier of the Fengxi District of Chaozhou City", set up a special class, implement unified command and unified management, effectively strengthen on -site safety management, and strive to reduce other times due to the water cavity water hydroception. Safety accident.

Talking about how to completely solve the problem of water in the cave, the person in charge helplessly said: "Two train bridges and culverts are low -lying and water flows to low places. The commonality of the train bridge culvert. In this regard, we are currently taking governance measures such as strengthening management, improving water pumping capacity, and dredging pipelines in a timely manner. We will also continue to strengthen research and learning, timely seek help from drainage experts, allow them to provide optimization plans, and try together to try together. Solving the problem of culverts for water. "

Departmental action

Do a good job of traffic control to ensure the safety of people and vehicles

Whenever the stream of water in the cave, what measures do the traffic police department take?

According to Chen Ruiwu, the second squadron instructor of the three brigades of the traffic police area, the second squadron was mainly responsible for the traffic management of Zhanhong Road Train Bridge Cave. He said that there has been a long time for Zhanhong Road Train Bridge Citrus to accumulate water. Once the rain is too heavy or continued to rain for a long time, culverts are prone to stagnant water. In order to quickly grasp the accumulation of Han cave, the Second Squadron adopted the method of combining on -site patrols and monitoring. As soon as they discovered the water in the cave, they immediately rushed to the scene to do traffic control and prohibit vehicles from passing. At the same time, contact Chaozhou Radio to report the prompt information of Handong Road in a timely manner, reminding passing vehicles by detouring.

Chen Ruiwu said that each time the police needed about 3 to 4 traffic policemen, they pulled up safety alert slogans on both sides of Handong, placed the "ice cream tube", and directed the vehicle by vehicle bypass. Some time ago, there were many rainfall days in our city, and traffic police officers came to the scene to control traffic control every day. In the middle of the night, they had to rush to the scene as soon as possible. "No matter how dark the sky is, how big the rain is, we all have to manage the traffic of the culvert to ensure everyone's personal safety and prevent accidents." Chen Ruiwu said that in general, the recovery time of culverts is 1 to 2 days, and the traffic time is 1 to 2 days. It takes 3 to 4 days when the rain is heavy. During the period, the traffic police department will send people to patrolling near Hantong to deal with the emergencies.

The Fengtang Squadron of the Chaoan Branch of the Municipal Public Security Bureau is responsible for the traffic management of Zhenchaonan Road Train Bridge Cave. Captain Cai Youyan, the team of the team, introduced that the Fengtang Squadron also learned about the road conditions near Handong through daily inspections and monitoring videos. "On rainy days, due to sewage pouring, the stagnant water of the train bridge culvert on Zhenchao South Road is more difficult to excrete. The recovery time of the culvert takes 5 to 6 days, and it will even take a week when the stagnant water is severe."

It is understood that although the traffic police personnel have done enough traffic control measures, a small number of drivers still pass through the water flow of the water in the cave. At this time, the traffic police officer had to rush to the site to rescue the trapped persons and contacted the trailer company for trailers. During the interview, traffic police officers admitted that whenever Han Dong had accumulated water, the traffic police department had to invest more manpower and material resources for traffic management to avoid accidents. They want to solve the problem of water accumulation as soon as possible to ensure the safety of the people. Next, the traffic police department will cooperate with the relevant functional departments to do a good job of governance to maximize the safety traffic around the road around Citrus.

■ Suggestions

Li Jinjia, a representative of the Municipal People's Congress:

Construction of most vehicles for cross -rail viaduct drainage

"I occasionally take the two train bridge caves of Zhenchao South Road and Zhanhong Road, Fengxi District. Last year, because I didn't pay attention to the warning sign, when I passed by Zhanhong Road Train Bridge Cave, I was scraped off by the stagnant water. "Li Jinjia, a representative of the Municipal People's Congress, said that after learning the severity of these two culverts, he went deep into the scene to understand the water accumulation.

Li Jinjia learned that since the completion of the Guangmeishan Railway, these two culverts will be severely accumulated every rainy. Although the previous two years had undergone a large rectification, the drainage pipe also increased, and the large -flow drainage pump was replaced, but the problem of water accumulation and difficulty in travel has not been resolved.

So, how to solve the stagnant problem of two train bridges on Zhenchao South Road and Zhanhong Road?

Li Jinjia believes that, first of all, the original railway culvert will no longer be transformed. Two railway caves of Zhenchao South Road and Zhanhong Road have been transformed in 2020, and the effect after the transformation is not significant. The main reason is that the culvert is too low -lying, and the increased high -power pump cannot be effectively pumped; secondly, it is recommended to build a cross -rail viaduct on Zhendong Road and Zhenchao South Road, and to drain most of the vehicles leading to the culvert to the viaduct. This can be effective Reduce the negative impact of culvert hydroception on the traffic of the vehicle. Or use a ceiling to block these two sections. The cover should be appropriately relaxed, and the culvert is needed to cover the cover to avoid oblique splashing due to the gravity of the wind. The purpose is to drain the rain to the rest and reduce the amount of water flowing into the culvert. And set up a large drainage system in front of the section before the cover to allow the flowing water to flow into the culvert. It is worth noting that whether the construction of the ceiling will affect the driving of the train and the surrounding buildings, and further research and discussion will be further studied; in addition, the train bridge cave and the Zhanhong Road train bridge culvert on Zhenchao South Road can lead to Yinhuai West Road. If you can speed up the construction of Yinhuai West Road and broaden the road, then the traffic of the two culverts can be drained to Yinhuai West Road to reduce the traffic pressure of culverts. In addition to the construction of Yinhuai West Road can effectively solve the problem of restricting vehicles because of Zhanhong Road and Zhenchao South Road Train Qiaodong Cave, it can also change the traffic travel problems in the west of Fengxi District and the south of Guxiang Town, Chao'an District.
