The old community changes the "new artery", and the qi of residents is more assured

Changsha Evening News, Changsha, August 16th (All Media Reporter Zhou Huixia) The gas pipe network is the "arteries" of the orderly operation of the urban economy. The operation is directly related to the safety of residents' lives and property. From the beginning of July to the end of October, Changsha City has carried out the "100 -day action" of gas safety in Changsha City, and concentrated on the prominent problem of gas safety in the field of gas safety. One of the focus is on the renovation and renewal project of the gas pipeline network of old communities. Changsha Xin'ao Gas Co., Ltd. After the early rehearsal, the overall transformation and update of 185 old municipal stem pipes, courtyard burial pipes, and outdoor pipelines were completed before the end of the year. How does the gas pipe network in the old community make overall updates? What is the progress? Yesterday, the reporter followed the company's maintenance personnel to visit on the spot.

"Master, our residents reported that the yellow gas pipes under the wall downstairs are a bit rusty, and there will be hidden dangers. Can you check it now?" A resident of a new village of Science and Education New Village saw the construction of Changsha Xin'ao gas construction construction. After the personnel, the construction staff hurriedly led the construction staff to the inspection.

The New Village of Science and Education is an old community with a history of more than 20 years. The gas pipe network laid in the community connects more than 1,900 residents and has been running for 22 years. In the southeast corner of the community, I saw a gray enclosure on both sides of the neighborhood road at the front of the community. The banner or logo of the word "gas pipeline transformation, please pay attention to safety". The passages between multiple buildings are also blocked by the road sign, and a gully nearly one meter deep was dug on the road. From time to time, the construction staff wearing a yellow work clothes poked out from the ditch to replace the tools in their hands. They are busy laying the updated pipeline.

Tang Zeying, the person in charge of the operating team of Changsha Xin'ao Gas West Management Network, introduced that this is the update and transformation of the gas pipelines of the new village of science and education. By reintering and re -buried the pipeline, the new energy arteries replace the existing pipeline network, and the gas gas safely can safely land safely. Transfer to millions of households.

Tang Zeye said that at the beginning of the completion of this community, he used oil asphalt coating anti -corrosion steel buried pipes, which was poor. At that time, the burial depth was only 40 cm. It was corroded by sewage and rainwater, and there were hidden safety hazards. Therefore, the annual complaint rate of this community in the past three years is more than 10, and construction workers often need to repair the rust of buried steel pipes. Based on daily maintenance and repair situation and evaluation of the security status of the pipe network, they include the renewal and update project of the old community pipeline network of science and education in the pipeline network, so that the people are safer and assured.

It is reported that the renovation and update tasks of the entire community pipeline network are not light, including the invisible buried pipeline of 6 kilometers long, the total length of about 2 kilometers is about 2 kilometers. It is expected to be completed by September. The renovated gas pipe network will be buried to about 70 cm underground. The new PE pipe is selected. The design life is not less than 50 years. It is not only resistant to corrosion. time. In order to facilitate the accurate foundation of the new pipe network during the later maintenance, the construction staff also collects the absolute coordinates of the new pipe network through the satellite positioning terminal equipment to locate the pipeline.

During this period, will the qi use of residents be affected? According to the relevant person in charge of Changsha Xin'ao Gas Co., Ltd., the underground pipelines of the old community are complicated. Due to safety requirements, the wiring of the gas pipeline has certain safety design standards. Therefore, before the pipeline of the old community is fully updated, the gas company will ensure the operation of the old pipe network and maintain the repair as usual, and minimize the impact of construction on residents' lives.

The reporter learned that the update and transformation of the old community pipeline network this year as the focus of the gas safety guarantee work. The transformation of the internal and external risers has a total of 185 projects, which is planned to be completed by the end of this year.
