Deep foundation pit supporting structure with high impact resistance

Abstract

The invention discloses a deep foundation pit supporting structure with high impact resistance. The deep foundation pit supporting structure comprises a supporting frame arranged inside a deep foundation pit and used for supporting, one side of the supporting frame perpendicularly abuts against a soil layer on the side wall of the deep foundation pit, a plurality of buffer plates are arranged on the other side of the supporting frame at intervals in the vertical direction, a plurality of supporting plates extending upwards to the top of a soil layer of the side wall of the deep foundation pitare arranged at the top end of the supporting frame at intervals, the bottom end of the supporting frame is connected with a bottom plate, and a plurality of sets of fixing pins capable of being inserted into the bottom face of the soil layer are arranged on the lower end face of the bottom plate. According to the deep foundation pit supporting structure, fixing inserting pieces, anchor rods, fixing plates, the fixing pins, sleeves and clamping teeth are arranged, before the supporting frame is installed, a soil layer is drilled, when the supporting frame is installed, the fixing inserting pieces are aligned with open holes in the soil layer, after the supporting frame is installed, enough concrete is injected into the open holes in the soil layer, then the fixing inserting pieces are inserted into the open holes, so that the anchor rods are in full contact with the concrete, after the concrete is solidified, the anchor rods are fixedly connected with the soil layer.

Description

technical field [0001] The invention belongs to the field of deep foundation pit support, and in particular relates to a deep foundation pit support structure with strong impact resistance. Background technique [0002] Deep foundation pit engineering refers to: (1) earthwork excavation, support, and dewatering works for foundation pits (troughs) whose excavation depth exceeds 5m (including 5m); (2) although the excavation depth does not exceed 5m, the geological conditions, The surrounding environment and underground pipelines are complex, or the earth excavation and support of foundation pits (troughs) that affect the safety of adjacent buildings (structures); construction accidents of deep foundation pits occur frequently, and once accidents occur, it is easy to cause mass death The consequences are quite serious. The main reason is that the construction plan and various safety pre-control measures during the construction process are not in place. During the construction ...
