Embodiment 1

[0025] Such as figure 1 The illustrated safety protection device for a pipe gallery foundation pit includes a steel bar 1, a side wall of the steel bar 1 is welded with a plurality of steel sheets 2 equidistantly, and the surface of the steel sheet 2 is provided with a hole. The distribution heights of the steel sheets 2 in 1 are all equal, and a steel wire rope 3 penetrates through each row of the holes, and the steel wire rope 3 is connected to the steel bar 1 through the steel sheet 2.

[0026] The distance between the steel sheets 2 is 375 mm; the steel sheet 2 located at the uppermost end of the steel bar 1 has a distance of 275 mm from the adjacent steel sheet 2 and a distance of 100 mm from the uppermost end of the steel bar 1.

[0027] The steel bar 1 is a φ18 steel bar with a length of 1500 mm.

[0028] The size of the steel sheet 2 is 40mm*50mm, and the diameter of the hole is 20mm.

Abstract

The invention provides a pipe gallery foundation pit safety protection device and a construction method. The pipe gallery foundation pit safety protection device comprises steel bars. A plurality of steel sheets are equidistantly welded to one side of each steel bar. The surface of each steel sheet is provided with a hole. The distribution heights of the steel sheets on each steel bar are equal. Asteel wire rope passes through each line of holes and connected with the corresponding steel bar through the corresponding steel sheets. Through research and application on the pipe gallery foundation pit safety protection device, the problems that the reinforcement effect of a traditional side slope is poor, the later maintenance frequency of the constructed side slope is high, one window time exists from completion of construction to achievement of the protection effect and the cost is high can be solved; moreover, the formation technology of the pipe gallery foundation pit safety protection device reaches the national advanced level. The pipe gallery foundation pit safety protection device has very high promotional value and remarkable economic benefits and social benefits.

Description

Technical field [0001] The invention relates to the technical field of construction engineering safety and protection facilities, in particular to a pipe gallery foundation pit safety protection device and a construction method. Background technique [0002] my country’s underground integrated pipe gallery has achieved rapid development in recent years. The importance of the underground integrated pipe gallery has gradually been recognized by more and more cities. The underground integrated pipe gallery has become an indispensable supporting municipal facility in the city. Pipe gallery construction is carried out on the road. The construction of the pipe gallery will cause vehicle congestion. In some turning places, vehicles are likely to collide with the construction fence and cause traffic accidents. In serious cases, vehicles can crash into the fence and fall into the deep foundation pit of the pipe gallery. Cause serious traffic accidents, [0003] Therefore, the present inventi...
