Description

Technical Field

[0002] Due to the complexity of the urban underground pipeline network and the uneven foundation structures of adjacent buildings, there is not enough space for slope reduction in the pipeline trench. In the local sections with potential collapse risks, slope reduction cannot be carried out and only temporary support can be carried out. However, temporary support takes a long time to construct and is expensive, disturbs the soil, and produces mechanical noise. With the continuous acceleration of urbanization, the excavation depth of water supply pipelines continues to increase, and the space for excavation and slope reduction is becoming more and more limited. Local temporary support of trenches is becoming more and more common. At present, there are more economical and recyclable support piles, such as steel sheet piles, Larsen piles, SMW method piles, etc. However, the above traditional support methods generally have problems such as high cost, limited scope of application, and long construction time. Even when constructing in trenches without slope reduction and support, accidents of trench collapse causing casualties are common. Summary of the invention
