Among them, there are 47 water pipes with a total length of 183km, accounting for 89%. The project has the characteristics of long water transmission lines, many points and wide areas, and a large management span. With the smooth progress of the project and the increase in pipeline working surfaces, the safety risks of pipeline deep foundation trench operations have gradually increased.

[0003] Specifically, in water pipeline projects, deep trench excavation in some sections cannot be sloped due to the surrounding environment and topography, and vertical surface excavation is required. Due to the limitations of the base geology and the surrounding environment of the operation, there are no conditions for steel sheet pile protection construction. However, temporary protection measures such as spraying concrete are used for vertical surface slope protection, which greatly increases construction costs and affects the progress of pipeline construction, causing idleness of on-site machinery and equipment, thereby affecting the overall benefits of the project. If no protective construction is carried out, the installation of pipeline steel pipes requires welding, anti-corrosion, concrete pouring and other construction processes in the deep trench foundation pit. The construction time is long, and the vertical surface slope is prone to landslides during long-term operation in the deep trench foundation pit, posing a great safety risk. Utility Model Content
