At present, the construction of the provincial capital underground comprehensive pipe gallery is in full swing. On April 20, the reporter learned from Shishi housing and urban rural development bureau that the 45 km underground comprehensive pipe gallery has been completed by 60%, and is planned to be completed by the end of the year.

    The comprehensive pipe gallery is to build a tunnel space under the city, which integrates various engineering pipelines such as power, communication, gas, heat supply, water supply and drainage, and has a special maintenance port, hoisting port and monitoring system. It is an important infrastructure and "lifeline" to ensure the operation of the city. As the only national pilot city of underground comprehensive pipe gallery, Shishi plans to build 18 pilot projects of underground comprehensive pipe gallery, a total of 45 kilometers.

    On April 20, at the construction site of the underground comprehensive pipe gallery of Huiming Road, the outline of the control center building has been shown, and the main structure is under construction. Most of the main works of the underground pipe gallery have been completed, "the reinforced structure in this area has been completed, and the next step will be concrete pouring." The relevant person in charge of the construction unit told the reporter that the open excavation construction method is adopted for the underground comprehensive pipe gallery, and the main part of Huiming road section is planned to be capped in the first half of this year. The control center expects to complete the main works by the end of April.

    The reporter walked into the underground pipe gallery along the escalator, which is very wide, and can run two cars side by side. The ground has been poured with concrete very flat, and the top and wall have been painted. "This is the heat warehouse, the larger of the five warehouses. In the future, thermal pipelines will be installed on both sides, and engineering vehicles can be run in the middle. " The relevant person in charge of the construction unit said that the underground comprehensive pipe gallery of Huiming road is located about 8 meters deep and 18-22 meters wide underground, which is designed as five storehouses. The pipelines into the gallery include water supply, renewable water, power, communication, heating, sewage and gas pipelines, which are large-scale projects under construction.

    "According to the plan, the 45 km underground comprehensive pipe gallery in our city will be completed this year, and the operation of the gallery is also in full progress." According to the relevant person in charge of the municipal housing and Urban Rural Development Bureau, the underground comprehensive pipe gallery under construction in Shishi City is divided into two parts: the old urban area and Zhengding new area. Up to now, Huiming road and Cangfeng road section project have formed a total of 7.36 kilometers of the gallery. The shield construction of the northern section of the tower combined with the subway project is in progress, and Zhengding new area has formed 18.7 kilometers of the gallery. In the future, the use of the underground comprehensive pipe gallery will avoid the impact and interference caused by the frequent excavation of roads due to the laying and maintenance of underground pipelines, and maintain the integrity and beauty of the road appearance. At the same time, it greatly facilitates the maintenance and repair of electric power, communication, gas, water supply and drainage and other municipal facilities, and reduces the cost of repeated road renovation and engineering pipeline maintenance.
