Although the heavy rain in July last year did not cause a large area to stop gas, it still caused serious damage to Zhengzhou China Resources Gas. Nowadays, the footsteps of time have entered the threshold of July, and the upcoming "seven or eight upper" is the critical period of the Central Plains flood control. What are the preparations for Zhengzhou China Resources Gas? What measures have been implemented?

On the afternoon of June 30, in the third northeast corner of the East Third Ring Road East Ring Road East Road, Zhengzhou China Resources Gas Third Storage Station. At the same time, the leakage instrument is also held to monitor the machine and equipment in the equipment area.

There were 300 meters in the west wall of the north and south. In the heavy rain in July last year, three places collapsed, up to 40 meters long. Therefore, in each inspection of this year, this wall has become the key "care" object.

Zhengzhou China Resources Gas Third Storage Station, which was launched in 2006, covers an area of ​​95 acres. It is mainly engaged in LNG (liquefied natural gas) storage, gasification, loading and unloading and LNG production and peak. The LNG storage tank of rice has a natural gas reserves of 2.1 million m³, which is equivalent to the gas consumption of Zhengzhou in summer.

"When natural gas is surplus, we turn the gas and natural gas into liquefied natural gas; when the natural gas supply is insufficient, we will then transform the liquefied natural gas into the gas of the gas to the urban pipe network for peak transfer. Therefore, for Zhengzhou citizens, the third is third The role of the storage and distribution station is very important. "Zhang Wei, the head of the third storage station of China Resources Gas at the Zhengzhou China Resources Gas, said that in the past 16 years, with the changes in the external environment, the station area is getting lower and lower. Blind.

"In order to avoid the occurrence of collapse, we built a 3.6 -meter -high wall at the collapse of the wall. Among them, 1.5 meters in the lower part are steel mixed structures, and the upper part is a brick -concrete structure to ensure the safety of the flood this year." Zhang Wei said.

It is reported that there are 7 gate stations and 3 storage stations in Zhengzhou City. In the rainstorm last year, some of them were collapsed due to rainstorms, road damage, water penetration of the station building, cracking of the wall, and the main control room and cable ditch. Today, the problems exposed last year have taken flood control measures.

【Pipe Network Transformation】

After digging in front of the trenches, layout and cooperate with tacit understanding. This year, 150 kilometers are transformed.

"These two tubes are polished and can be laid!" At 10 am on June 30, the workers were digging the pits in the family courtyard of the North China Petroleum Bureau in Qinling Road and Longhai Road in Zhengzhou City. Two construction personnel of the gas are polishing the gas pipeline and are ready to put them in the pits.

What they are ongoing is the renovation of the old pipeline network of the family.

There are 6 buildings in the Family Council of North China Petroleum and 260 households. The gas pipelines laid in 1989 are about 300 meters. It has been 33 years. Especially the flood season has hidden safety hazards.

"This year is the year of improvement of the safety capacity of Zhengzhou China Resources Gas. One of the important tasks is to transform the old pipe network to completely eliminate hidden safety hazards." Li Changjiang, director of Zhengzhou China Resources Gas Safety, said that Zhengzhou attaches great importance to the transformation of the old pipeline network. After repeated investigations, the government was finally decided to excavate and recover the pipeline ditch, while China Resources Gas is responsible for the installation of pipeline pipelines, and residents do not need to pay. Only this, they invested 100 million yuan. (Tube.com renovation site)

Elephant reporters saw at the old pipe network reconstruction site that the two sides cooperated with each other, and the pipeline was laid after digging in front of the trench, followed by backfilling to minimize the impact of the transformation to the residents.

"The new pipeline length of the Family Council of the North China Petroleum Bureau is about 450 meters. We closely cooperate with the government's trench excavation progress. After the trench excavation is completed, the pipeline will be paved within 24 hours. The government construction unit will be filled back. After finishing. "Guo Yan, director of the Western Pipeline Institute of Zhengzhou China Resources Gas Pipe Network, said.

According to Li Changjiang, according to the plan, this year will be transformed 150 kilometers of old pipe network, and 200 kilometers will be transformed next year.

【Pipeline inspection】

Once rainfall occurs, focus on the dangerous area of ​​inspection

On the morning of June 30, the rainfall appeared in Zhengzhou. When the rain was large, it was small and intermittent, and Guo Yan, director of the Western Pipeline of the Western District of Zhengzhou China Resources Gas Pipe Network, couldn't sit still. So he drove immediately and drove to the Mazhai Industrial Zone.

In the past year, as soon as he encountered rainfall, Guo Yan was not very solid in his heart. What made him miss is the landslide located on the Kangjia Road in Mazhai Industrial Zone.

At 4:50 am on July 21 last year, the Zhengzhou China Resources Gas Dispatch Center contacted the Municipal Flood Control Command to confirm the flood reference plan of the Guojiazui Reservoir. At 5:45 am on July 21, the valve and valve of the Mazhai pressure regulating station in and out of the station The room was closed, and the Mazhai Industrial Zone stopped gas. At 9 am on the same day, the patrol staff found that the east collapse of 200 meters south of Tianming Road, Kangjia Road, Mazhai Industrial Zone, and the middle pressure gas pipeline was suspended for 50 meters. Fortunately, no air was leaked.

On July 25, the suspension protection of the Kangjia Road suspended pipeline was carried out, and after the test was not leaked, the air supply of the middle pressure pipeline of Kangjia Road was restored.

On September 1, the rainfall again caused the dangerous situation of Kangjia Road. New landslide points appeared 20 meters south of the south side of the collapse. The new collapse was 20 meters in length. As the rain weakened the weather, it was not until 11:28 am on September 5 that it was restored to the middle pressure pipeline of Kangjia Road.

"When the middle pressure pipeline in Kangjia Road is in a suspension state, the rescue personnel of the Western District Pipeline inspect the Kangjia Road suspension pipeline every day to confirm that the pipeline does not leak air. Later, after the local government repaired the landslide here, it became the collapse and became the landslide. The key care objects of the patrol staff. As long as we encounter large rainfall weather, we will tour the line to ensure safety. "Guo Yan said.

In fact, during the heavy rainstorm last year, in the low -pressure pipelines in Zhengzhou City, 415 dangerous situations appeared due to the collapse of roads and walls, and 92 air suspension of gas stopped, affecting 112 communities, 35751 households, and 107 commercial users. The dangerous situation of the Mazhai Industrial Zone is just a typical case.

【Equipment and Materials】

"Mobile warehouses" should fight at any time, and four measures ensure safety

("Mobile warehouse" can be fought at any time)

"Ready to set off!" At 11 am on June 30th, Zhengzhou China Resources Gas Pipeline Network Running Department West District Pipeline and maintenance center courtyard on the northwest corner of Kunlun Road, Ruhe Road. After checking the status of the vehicle and the equipment they, they launch a rescue vehicle inspection on the street.

These two yellow rescue vehicles are presented in the second half. Open it, the generator, pumping pump, life jacket, raincoat, rubber boots, safety rope and other flood control facilities are available. Ready to rescue.

In addition to the "mobile warehouse", there are also flood control materials warehouses and equipment warehouses in the courtyard. Various flood control materials are sufficient. As long as the flood conditions occur, they will immediately enter the battle.

"In view of the challenges brought by the heavy rain last year, this year we have been determined to be a year of safety capacity improvement. It mainly starts from four aspects to do a good job of safety and flood." Li Changjiang, the director of the safety of China Resources Gas, said, one is to do a good job of old and older old -fashioned old -fashioned. The pipe network transformation, the second is the installation of safety devices for gas users, the third is to upgrade major emergency equipment, and the fourth is to build a gas warning monitoring platform.

Li Changjiang said that the installation of safety installations of gas users started from June this year. The main content is to install auto -closed valves and replace metal hose for residents to ensure the safety of the people's lives and property, and to create a safe gas city. As the top ten people's livelihoods in Zhengzhou this year, it plans to install 800,000 households this year, and 1.7 million households will be installed next year.

In terms of upgrading major emergency equipment, a large number of flood prevention equipment was purchased this year. Among them, high wading special vehicles are a highlight. As long as the area of ​​water is not more than 1.5 meters, it can drive normally and rush to the rescue location.

"In addition, Zhengzhou Gas Early Warning Monitoring Platform is under construction and is expected to be initially formed in August." Li Changjiang said that the platform has achieved remote monitoring and automatic induction of high -risk areas, high -consequences and high -sensitive areas. Once discovered, it is discovered. The danger can be dealt with quickly and minimize the loss.
