Abstract

The invention provides a foundation pit excavation method for soft plastic soil, which relates to the technical field of underground engineering. The earthwork excavation method is formed by paving and filling the excavation surface in time to form a hardened layer. The hardened layer can not only meet the requirements of construction machinery operation Bearing capacity requirements, it can enhance the stability of the slope during the grading process, and can effectively control the damage of the excavation surface by the rheology of the soil, so as to maintain the stability of the empty surface of the soil lying under the excavator and realize the earthwork excavation construction The smooth progress of the existing technology alleviates the technical problems that the on-site construction machinery cannot operate normally, and the rheology of soft soil causes the destruction of the excavation surface of the foundation pit; the foundation pit excavation for soft plastic soil provided by the present invention The method can provide a feasible construction method for earthwork excavation in soft soil areas, and can be popularized and applied in foundation pit engineering in soft soil areas.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to a foundation pit excavation method for soft plastic soil. Background technique [0002] With the development of the economy, due to the requirements of the buried depth of high-rise buildings, the increase in garage area and other requirements under the condition of limited floor area ratio, soft soil areas involve more and more foundation pit projects; foundation pit projects not only need to ensure The safety of self-construction requires strict control of the impact on the surrounding environment. For excavation of foundation pits in soft soil areas, the characteristics of soft soil will seriously affect the safety of foundation pits, and will also affect the quality of engineering piles and basement construction quality . [0003] In the prior art, during the excavation of foundation pits on soft plastic soil, there will be the following problems: 1) On-site ...
