Gravel foundation pit enclosure structure

Abstract

The invention discloses a gravel foundation pit enclosure structure. The structure comprises guardrail bodies, a fixing mechanism, fixing blocks, fixing holes, locking mechanisms, a fastening mechanism, compression springs, pressing rods, a push rod, an extrusion spring, push blocks, a telescopic spring and a pressing plate. The structure has the beneficial effects that bolts and the fixing blocks are fixed to the ground through a plurality of fixing holes, after the bolts are inserted into the fixing holes, the bolts can abut against baffles to rotate so as to abut against the push blocks to move, one ends of the push blocks abut against the pressing rods to get rid of the acting force of the compression springs to move downwards, and a plurality of push rods abut against the ground outside the fixing blocks. The fixing blocks are fixed to the ground more stably and firmly, meanwhile, dismounting and transferring are convenient without damage, the fixing blocks are convenient to recycle repeatedly, resource consumption is reduced, then the bottoms of the guardrail bodies are inserted into the fixing blocks correspondingly to be clamped, under the action of the locking mechanisms, the guardrail bodies are convenient to dismount and take out, and the mounting and dismounting efficiency of the guardrail bodies is improved.

Description

technical field [0001] The invention relates to an enclosure structure, in particular to an enclosure structure for sandstone foundation pits, and belongs to the technical field of foundation pit enclosures. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. If the excavation is not deep, you can use the method of setting the side slope to stabilize the soil slope. The slope size is determined according to the relevant construction regulations. In order to protect the surrounding environment at the sandstone foundation pit site, it is necessary to install enclosures near the sandstone foundation pit. The guardrail is fenced, thus playing the role of safety protection. [0003] However, traditional fences are directly fixed and connected to the ground through expansion bolts, which are cumbersome to install, disassemble and move. After a long time, the bolts a...

Problems solved by technology

[0003] However, traditional fences are directly fixed and connected to the ground through expansion bolts, which are cumbersome to install, disassemble and move. After a long time, the bolts are likely to rust, which is inconvenient for subsequent disassembly. In severe cases, the fence will be damaged, resulting in a lot of waste of material
