Foundation pit supporting protection structure

Abstract

The invention relates to a foundation pit supporting protection structure. The foundation pit supporting protection structure comprises supporting piles, anchoring parts, chains, motors and displacement sensors; the anchoring parts are fixedly arranged on the ground on the sides of a foundation pit; the motors are fixedly arranged on the anchoring parts; one ends of the chains are fixedly connected with the output ends of the motors; the other ends of the chains are detachably connected with the tops of the supporting piles; the displacement sensors are arranged on the anchoring parts and areused for detecting horizontal displacement of the anchoring parts and outputting horizontal displacement information; the motors are connected with a control system; the moving directions of the anchoring parts towards the supporting piles are set to be positive directions, and the horizontal displacement information in the process that the anchoring parts move towards the supporting piles is setto be forward displacement information; the control system is connected to the displacement measures; the control system responds to the forward displacement information, acquires the rotation angle of the output ends of the motors according to a preset calculation relation between the forward displacement information and the output ends of the motors, and drives the chains to wind. The foundationpit supporting protection structure has the effect that the tops of the supporting piles are not prone to large deformation when the supporting piles are under lateral soil pressure.

Description

technical field [0001] The present application relates to the technical field of building foundation pits, in particular to a foundation pit support and protection structure. Background technique [0002] The pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. If the excavation is deep and there are buildings nearby, the method of foundation pit wall support, shotcrete wall protection method, large foundation pit or even underground diaphragm wall and column type bored pile interlocking method can be used. [0003] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the lateral earth pressure generated during the walking and operation of the thousand-ton crane cannot play a good stabilizing effect, which may cause the top of the supporting structure to bend inwards of the foundation pit , which in turn may affect the building construction on th...
