Abstract

The invention discloses a safety protection device for a municipal engineering foundation pit. The safety protection device comprises a lower shell. The safety protection device is characterized in that a plurality of middle shells are fixed to the top of the lower shell through bolts, wherein an upper shell is fixed to the tops of the middle shells through the bolts; a lifting motor is fixed to the top of the upper shell in a welding manner; an output shaft of the lifting motor is movably connected with a lead screw through a coupling; the lead screw penetrates through the inner walls of theupper shell, the middle shells and the lower shell, one end of the lead screw is in contact with the inner wall of the bottom of the lower shell, and the exterior of the lead screw is movably connected with pedals through a ball nut pair; guide rails are connected between the inner wall of the top of the upper shell and the inner wall of the bottom of the lower shell, and the guide rails are in sliding fit with the pedals; a notch is formed in one side of the upper shell; a first escape door is arranged at the notch; and the cross section of the lower shell is in a C shape, and the lower shellis of a hollow structure. The safety protection device has the characteristics of good safety performance and rapid evacuation.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a safety protection device for foundation pits of municipal engineering. Background technique [0002] Deep foundation pit construction is an important part of urban infrastructure construction. At present, the development of urbanization is getting faster and faster, the urban population is increasing, and the complexity and difficulty of municipal engineering are further increasing. Improving the safety of building construction has become an urgent problem to be solved. [0003] Due to the influence of various bad weather, the construction of the foundation pit may face many problems caused by bad emergencies, such as soil loosening and earthquakes, causing the foundation pit to collapse. Hazard to the life safety of staff. Therefore, it is necessary to design safety protection devices for municipal engineering foundation pits with good safety performance and r...
