Abstract

The invention discloses a foundation pit protection system based on deep foundation pit excavation and a protection analysis method. The foundation pit protection system comprises an excavated foundation pit, a protection device is arranged on the periphery of the top of the foundation pit, the protection device comprises a base, a protection net is arranged above the base, and a height adjusting mechanism is arranged in the base; the height adjusting mechanism comprises a two-way lead screw rotationally connected to the left side and the right side of the inner wall of the base, moving blocks are in threaded connection to the left side and the right side of the outer surface of the two-way lead screw, a lifting plate is slidably connected between the inner walls of the base, and first rotating rods are rotationally connected to the front side and the rear side of the top of the moving block on the left side; the invention relates to the technical field of foundation pit protection. According to the foundation pit protection system based on deep foundation pit excavation and the protection analysis method, through the arrangement of the disassembly and assembly mechanism, rapid disassembly and assembly of the protection net are achieved, so that the protection net is conveniently cleaned and maintained, and the service life of the protection net is prolonged.

Description

technical field [0001] The invention relates to the technical field of foundation pit protection, in particular to a foundation pit protection system and a protection analysis method based on deep foundation pit excavation. Background technique [0002] The foundation pit is a soil pit excavated at the base design position according to the base elevation and the size of the base plane. Before excavation, the excavation plan should be decided according to the geological and hydrological data and the conditions of the buildings near the site, and waterproof and drainage work should be done. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the size of the slope shall be determined according to the relevant construction regulations. If the excavation is deep and there are buildings nearby, the foundation pit wall support method, the shotcrete wall protection method, or even the underground diaphragm wall and the column-type bored pile i...
