With a noise, 40 -year -old Jing Pingshan Bridge completed the historical mission in 2024, and the original site across the Lijiang River will be reborn.

"I announced that the clean -up of the clean -boring mountain bridge was officially launched." At 14:28 on July 19th, with the order of the on -site blasting construction commander, the old bridge of the Ping Pingshan Bridge began to blast.

"Well!" I heard a loud noise. After 1 second, the smoke permeated, and the bridge broke down. The bridge that served the citizens for nearly 40 years to complete the historical mission.

After the construction unit completes the crushing of the beam body and the river clearance work, the Jing Ping Mountain Bridge Reconstruction Project will officially start construction. It is estimated that by the end of 2024, a brand -new net bottle mountain bridge will stand on the Lijiang River and re -serve the general public.

Born in 1983, it is the second bridge across the Lijiang River in the urban area

The Jing Pingshan Bridge connects to the south of the city and the south road of the ring city. It is named after 700 meters in the downstream of Jingbing Mountain. Important channels for traffic.

Time back. In Guilin in the 1970s, traffic in urban areas is also limited to the situation of "one north and south roads, east -west bridges". The "one road" is Zhongshan Road, which runs through the city of Guilin from the south; the "Bridge" is the liberation bridge of the East and West across the Lijiang River. With neither road nor bridge, residents on both sides of the strait must be detoured by the east and south of the city, which must be extremely inconvenient.

The spring breeze of reform and opening up all over the land of Guilin. In the 1980s, Guilin's economic and social development was rapid, and the population population continued to increase. The number of residents in the south of the city and the east of the city was increasing.

In this context, the Municipal Party Committee and Municipal Government decided to build a net bottle Mountain Lijiang Bridge (the original name of the Jing Pingshan Bridge). On September 29, 1980, it was designed by the former Shanghai Municipal Engineering Design Institute. The second place in the Bridge of the Bridge Engineering Bureau of the Ministry of Railways was responsible for construction. The bridge is a five -cross -section continuous beam bridge, with a width of 20 meters, two -way four -lane, and non -mixed machines.

In May 1983, the Jingbing Mountain Lijiang Bridge was completed. It was officially opened to traffic on November 17 of the same year. It is also the second bridge across the Lijiang River after the liberation bridge. Its completion and opening to traffic not only effectively solves the travel problems of the residents of the south of the city and the east, but also greatly promotes the integration and development of the economic and social and society of the Xingshan District and the Qixing District, and opened a new chapter in the history of Guilin City.

After 40 years of wind and rain, the net bottle mountain bridge is overwhelmed

After entering the new century, with China joining the World Trade Organization, Guilin's economic development has entered a period of "blowout": in the Qixing District of High -tech Zone, various industrial factories are scattered; The population continues to grow. As an important traffic node in the two places, the net bottle bridge has increasingly increasing vehicles, especially the high proportion of various heavy vehicles, which also gradually makes this bridge gradually overwhelmed.

According to the relevant person in charge of the Municipal Housing and Urban Construction Bureau of the Municipal Housing and Urban Construction Bureau, in December 2014, the department commissioned the inspection company to conduct a comprehensive inspection and inspection of the Jingbing Mountain Bridge. The technical condition was generally evaluated as the D -class bridge (that is, the state of unqualified). In order to understand the technical situation of the bridge, in 2018, the department commissioned the inspection company to conduct a comprehensive inspection and test of the bridge again, and conduct load test to make a comprehensive evaluation of the function and working status of the bridge: the technology of the bridge's technology The general assessment of the D -class bridge is generally evaluated. The assessment level of the bridge deck system and the upper structure is E -class (that is, the dangerous state).

With the approval of the municipal government, from June 4 of that year, the bridge management department has adopted the bridge to take high weights and weight -limit measures -2.8 meters high, 15 tons of weight, and speed limit of 30 kilometers/h.

The demolition and reconstruction of the bridge has also been gradually on the agenda. The Municipal Housing and Construction Bureau reported to the municipal government in July 2019 and April 2020 to request the bridge demolition and reconstruction. At the end of 2020, the municipal government officially approved the demolition and reconstruction of the net bottle mountain bridge.

Because the Jingbing Mountain Bridge needs to be demolished and rebuilt on the original site, the first key node to promote the project is to build a temporary steel bridge that ensures the traffic of the citizens. In this way, the main project of the Demonstration and Reconstruction Project of the Jing Ping Bridge can be officially launched. On May 11, 2021, the construction of the supporting project of the Demolition and Rebuilding Project of the Jing Pingshan Bridge was temporarily constructed and completed on September 16 of that year. The bowel bridge is 259.6 meters long, with a total width of 12 meters and a passing width of 10 meters. It is only for pedestrians and non -motor vehicles.

On January 5 this year, the construction ceremony was held in Jingbing Mountain Bridge demolition and reconstruction project.

From 23:00 on June 15th, the construction of the Jing Pingshan Bridge was fully closed in both directions, and Guilin City Nanfang Daoqiao Construction Co., Ltd. started the preparation of blasting demolition -the auxiliary facilities of the bridge deck, such as street lights, wires, expansion joints, etc. The trees are migrated, and the blasting drilling work of each pier has also been completed.

The old bridge explosion is demolished, and the new bridge will be completed at the end of 2024

On the afternoon of July 19, the clean -boring and reconstruction project hosted by the Municipal People's Government and the joint construction of the Municipal Housing and Construction Bureau and the Southern Daoqiao Construction Co., Ltd. -the old bridge blasting and demolition ceremony was held.

The first is a 1 -minute warning signal. Then, the staff of the on -site blasting group, the shore warning group, the water warning group and other groups successively successively reported the report of Wu Zhao, the person in charge of the Demolition and Reconstruction Project of Jingbi Mountain Bridge of the China Construction Eighth Bureau, the second Construction Co., Ltd. Preparations for various tasks. Then, the blasting corner of the blasting sounded for 1 minute, the blasting charging was completed.

Subsequently, Huang Xiliang, deputy secretary -general of the municipal government, pressed the explosor, and the old bridge blasting construction was officially implemented. After a burst of smoke permeated, the old bridge completely broke. A warm applause sounded at the scene. After ensuring safety, everyone came to the Lijiang River and recorded the last figure of the old bridge with a camera and mobile phone. According to the relevant person in charge of Nanfang Daoqiao Construction Co., Ltd., the old bridge blasting plan is based on the structure, site conditions and geological hydrogenics of the bridge, comprehensively considering construction conditions such as construction period, mechanical equipment and environmental protection requirements, and decided to choose the first one -time overall blasting after the overall blasting. The overall construction plan for mechanical demolition and cleaning. During the blasting, the box beams at the 1st, No. 2, 3, 4 pier and No. 2, and No. 3 pier were destroyed, resulting in the overall collapse of the bridge. After the bridge fell, the broken hammer was first used in accordance with the old bridge drawings to decompose each section of the box beams. The whole bridge was divided into 98 sections, of which 80 sections of the hanging basket construction. By removing prestressed reinforced steel bars and wet seams and cross -parts, the overall box beams are decomposed into segments, and then crushing and clearing work. After the blasting is completed, the equipment such as excavators will also be used for beams and the river clearance work, and the riverside navigation capabilities and flowing water will be restored in time to reduce the impact on the environment and society.

"After completing the relevant clearing work, the Jing Pingshan Bridge Reconstruction Project will be officially started." The person in charge said that the project is the owner of the Southern Daoqiao Construction Co., Ltd. Guilin Jianchang Construction Co., Ltd.; the project budget investment is 463 million yuan, the planned construction period is 3 years, and it is expected to be opened to traffic by the end of 2024. The main construction contents of the project include bridge new projects, bridge projects under Binjiang South Road, road projects, and supporting construction of affiliated projects such as water drainage, lighting, greening, transportation, power, and communication pipes. The main bridge of the newly -built Pingqiao Mountain Bridge is a three -span -section section continuous beam bridge. The bridge is 319 meters in length, the bridge and the lanes are 1016 meters long. Lane.

"In the past, because the old bridge was only 20 meters wide, it became a transportation bottleneck here, which often caused traffic jams. The new bridge is a two -way six -lane and set up non -motorized lanes and sidewalks to achieve non -separation of machinery. At the same time, the new bridge The width is the same as the road at both ends of the east and west. After the completion of the new bridge, it will effectively alleviate the problem of congestion. "The person in charge said that after the completion of the new bridge, in addition to effectively alleviating the problem of congestion, it will be more conducive The garden -centered group and the east -direction group centered on the Guilin National High -tech Development Zone and Tieshan Industrial Park to expand Guilin's urban space and improve the urban function. The company will urge the construction unit to optimize the construction plan, seize the construction period, and strictly control the quality of the project to ensure that the construction of the new bridge will be advanced as scheduled.

The person in charge reminded that during the construction of the project, non -motor vehicles and pedestrians can pass through the north side of the bridge; motor vehicles can bypass the city high speed, Longmen Bridge, and Lijiang Bridge. It is hoped that the general public will reasonably choose travel methods and planning travel lines, pass through the instructions of the traffic signs, and consciously obey the command of the traffic police and traffic order.
