Novel foundation pit safety protection device based on municipal road engineering

Abstract

The invention provides a novel foundation pit safety protection device based on municipal road engineering, and relates to the technical field of municipal engineering. The novel foundation pit safetyprotection device comprises a first mounting column and a second mounting column, wherein two symmetrical rotating blocks are fixedly connected to the two side surfaces of the second mounting column;a rotating plate is rotationally connected to the interior of each rotating block; a protection vertical rod is arranged in a crack between the two rotating plates; and the two ends of the protectionvertical rod are rotationally connected with the side surfaces, close to each other, of the two rotating plates correspondingly. According to the novel foundation pit safety protection device based on municipal road engineering, the first mounting column, the second mounting column, the rotating blocks, the rotating plates and the protection vertical rod are arranged, V-shaped design in differentdirections is adopted, and the mounting columns and the supporting plates are arranged in a sliding mode, so that the novel foundation pit safety protection device is used for foundation pits in different shapes, the size of the protection device is reduced during transportation, and storage and transportation are facilitated; and a fixing mechanism and a second conical plug are arranged, so thatthe problem that when an existing foundation pit protection device is used for protecting foundation pits of some muddy roads, a base is not fixed stably, and then a protective fence is toppled is solved.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a novel foundation pit safety protection device based on municipal road engineering. 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. If the excavation is deep and there are buildings nearby, you can use the method of foundation pit wall support, shotcrete retaining method, and large-scale excavation. The foundation pit even adopts methods such as underground diaphragm wall and column-type bored pile interlocking to protect the outer soil layer from collapsing. There is no influence on nearby buildings. The well point method can be used to reduce the groundwater ...

Problems solved by technology

[0003] Since the foundation pits are mostly geometric shapes with different shapes, most of the existing foundation pit protection devices are right-angled fences, which are inconvenient to use, and most of them cannot be stacked when stored after use, occupying a large space, and are not convenient for transportation. Although the existing patent technologies CN203145488U, CN205713186U, and CN207211951U have adopted the mutually rotatable splicing parts of the barbed wire frame to solve the technical problem that it cannot be applied to different terrains, the above solutions still have the following technical problems: the base of the foundation pit protection device When protecting the foundation pit of some muddy roads, the base is not fixed stably, resulting in the dumping of the guardrail. In addition, the fine adjustment of the enclosed area cannot be realized after the splicing is completed and initially fixed. With the progress of the construction If you want to expand or reduce the enclosed area, you can only pull out all the fences and reposition them. In addition, if you need to build a sunshade net or protective net on the upper part of the foundation pit in the central area of ​​​​the enclosure, you need to use external suspension equipment alone
