China News Service, Guangzhou, June 16 (Cai Minjie, She Yingwei) The Milin County Working Group of the Ninth Batch of Aid Tibet Task Force of Guangdong Province recently announced that the underground pipeline network exploration project in Milin County, Linzhi City, Tibet The project results will be handed over in the second half of the month. It is reported that this is the first project in Linzhi City to use ground penetrating radar technology to explore the underground pipeline network in the county and urban area.

The underground pipe network is regarded as the lifeline of the city. However, many cities in the mainland have a messy distribution of underground pipe networks, incomplete and irregular archives. The underground construction of construction projects is like “blind people touching the elephant”, which can easily cause mechanical equipment to damage the underground. Pipelines, and even cause major accidents.

In order to standardize the construction and management of underground pipe network in Milin County, and help the construction of counterpart aid areas in Tibet, Zhuhai took the lead in introducing ground penetrating radar technology into snow-covered plateaus for large-scale applications.

Move out the two-wheeled trolley and the ground penetrating radar, fix the laptop on the support plate above the trolley, connect the data cable, and run the acquisition software… This is Milin County, Linzhi City, Tibet Use ground penetrating radar to detect underground pipeline network.

“In terms of image, ground penetrating radar can perform non-destructive and comprehensive’physical examination’ on urban underground pipelines, with high efficiency and high precision , Low-cost features, allowing city managers to “prescribe the right medicine” based on the results of the “physical examination” to ensure the orderly and safety of underground pipelines.” According to Zhang, a member of the Zhuhai Aid Tibet Working Group, a member of the Party Group and Deputy Director of the Housing and Urban-Rural Development Bureau of Milin County According to Han, the project team used ground-penetrating radar and other technologies to detect municipal public pipelines such as power supply, communication, water supply, rainwater, sewage, street lights, monitoring, etc. without ground excavation, with a total detection length of 104.22 kilometers.

It is reported that the underground pipeline network exploration project will form the first complete basic database of county and urban government and public pipeline network information in Linzhi City, Tibet. “The underground pipe network will be’men’erqing’ from now on, and will provide support for the implementation of major national projects and urban expansion needs in Milin County in the future.” Zhang Han said.

In the exploration process of underground pipelines in Milin County, due to the variety of underground pipelines, various materials, different ownership units, burying time and burying methods are also different, the pipelines often cross vertically and vertically, and overlap up and down. The complex terrain and geological conditions of the plateau also make it difficult to accurately detect the direction and buried depth of various pipelines.

“In order to ensure the smooth implementation of the project, in the preliminary preparation stage, we collected the design and completion data of various pipelines within the survey area, carried out on-site verification, and organized relevant experts and the Shaanxi Engineering Survey Institute work team many times Discussing several easy solutions and breaking through multiple technical difficulties.” Zhang Han said, “The successful implementation of the project will provide technical data guarantee for urban management and urban construction in Milin County, and at the same time play an important role in the fine management of cities in plateau areas. Demonstration and leading role.”

It is reported that the sewage pipeline data obtained during the project exploration has been used by the projects under construction in Milin County, providing clear underground pipeline data for project construction. (End)
