Deep foundation pit supporting method
The invention provides a deep foundation pit supporting method. The method comprises the following steps of 1, excavating soil, wherein the excavation depth is 60-70 cm under a soil nail hole site, the excavation width ranges from 15 cm to 20 cm, the soil is divided into five layers for excavation, the first layer is 3.5-4 m thick, and the other layers are 1.0-1.3 m thick; excavation of the next layer of soil cannot be performed before soil nailing and concrete spraying of the upper-layer working face are completed; 2, conducting soil nailing and hole forming, wherein manual hole forming is performed at the corresponding position of soil nailing through a Luoyang shovel; 3, conducting soil nail manufacturing and placing; 4, conducting grouting, wherein unmixed cement mortar with the water cement ratio being 0.5 is injected into the hole; 5, hanging a reinforcing mesh and the like. The deep foundation pit supporting method can solve the deep foundation pit supporting problem, the overall stability of a side slope can be remarkably improved through a formed soil nail composite body, the construction technology is simple and convenient, construction does not need to occupy a site independently, the construction cost is low, and the construction speed is high.
