Henan zhongtong Industrial Co., Ltd. takes you to understand the shallow buried dark excavation method
● Introduction:
The shallow buried tunneling method is a method of constructing tunnels or underground projects close to the surface, which is suitable for urban soft rock environments. It transforms geological conditions and controls surface settlement, uses initial support such as grids and sprayed anchors, and follows the “New Austrian Tunneling Method” principle and the principle of “pipe advance, strict grouting, short excavation, strong support, fast closure, and frequent measurement” to design and construct tunnels.
● Advantages:
It can be carried out in densely built-up areas in cities, with shallow excavation depth, and the construction has little impact on ground transportation and buildings.
● Application scenarios:
It is used for the development of small and medium-sized underground pipelines, tunnels or underground spaces in cities, such as power tunnels, drainage tunnels, subway stations, etc.
