Problems solved by technology

However, for a long time, when there is more soil scattered on the slope, the pressure of the protective net will increase, which will easily cause damage to the protective net and reduce the service life of the protective net; and when the protective net is damaged, it needs to be replaced again, which is time-consuming strenuous

Embodiment 1

[0050] see Figures 1 to 6 , the embodiment of the present invention provides a deep foundation pit slope protection structure, the protection structure specifically includes:

[0051] Reinforcement mesh cavity, the lower mesh surface 21 is arranged close to the slope surface of the main body 1 of the foundation pit slope, and the aperture of the upper mesh surface 22 is smaller than the aperture of the upper mesh surface 21 and / or the upper mesh surface 22. The hole density of the holes is smaller than the hole density of the holes on the lower mesh surface 21 .

[0052] Specifically, the number of reinforced mesh cavities is four, which are respectively fixed on the four slope surfaces of the main body 1 of the foundation pit slope; and each reinforced mesh cavity includes: a bucket-shaped frame, and the upper trapezoidal frame of the bucket-shaped frame is fixed with a The upper mesh surface 22 and the lower trapezoidal frame are fixed with the lower mesh surface 21, and t...

Embodiment 2

[0063] see Figure 5 , in order to fix and reliably set the steel mesh cavity on the slope surface of the main body 1 of the slope of the foundation pit, the embodiment of the present invention also sets the following structure:

[0064] Four fixing frames, each fixing frame respectively fixes the corresponding steel mesh cavity on the slope surface of the main body 1 of the slope of the foundation pit; Slope); two transverse rods 34, respectively set on the upper and lower parts of the two base rods 31, and the two base rods 31 and the two transverse rods 34 enclose the space as a trapezoidal structure; four anchor rods 32, respectively set On the upper and lower ends of the two base rods 31; four "U"-shaped frames 33 (to facilitate the independent and reliable fixation of the upper mesh surface 22 and the lower mesh surface 21) are respectively located between the two anchor rods 32 On the base rod 31 and the cross rod 34; the connecting piece is used to fix the four sides ...

Embodiment 3

[0069] see Image 6 , in order to effectively transfer the scattered soil that reaches the top of the foundation pit to the ground to determine the position, the embodiment of the present invention also sets the following structure:

[0070] The side wall 61 of the transfer box 6 away from the main body 1 of the slope of the foundation pit is a slope surface structure (while ensuring that the scattered soil in the receiving container 5 is not spilled, the scattered soil in the transfer box 6 can be quickly and completely poured out. For receiving the scattered soil poured into the receiving container 5; the third motor 7, its rotating shaft is fixed with one side wall of the transfer box 6, and the rotating rod and the connecting block that are rotatably arranged on the other opposite side wall of the transfer box 6 Fixed connection.

[0071] The rods of the two telescopic devices 8 are respectively connected with the fixed part and the connection block of the third motor 7 ....

Abstract

The invention discloses a deep foundation pit side slope protection structure, comprising: a steel mesh cavity, the lower mesh surface of which is arranged in close contact with the slope surface of the main body of the foundation pit slope; a switch interface is used to control whether the scattered soil in the steel mesh cavity emits steel bars Net cavity; the moving device is used to push the receiving container to move horizontally at the bottom of the main body of the slope of the foundation pit, so that the receiving container is located directly below the switch interface, or to keep the receiving container away from directly below the switch interface; the lifting device is used to make the receiving container and The moving device moves up and down between the top of the main body of the side slope of the foundation pit and the bottom pit at the same time. When there is a lot of soil scattered on the slope, part of the scattered soil falls into the steel mesh cavity, and the receiving container is transferred to the top of the foundation pit through the mobile device and the lifting device, so as to ensure that most of the scattered soil does not randomly scatter to the foundation pit. In the case of pits, the pressure on the lower mesh surface is reduced to a certain extent, that is, the service life of the lower mesh surface is improved, and the inconvenience caused by replacing the steel mesh is avoided.

Description

technical field [0001] The invention relates to the technical field of foundation pit protection, in particular to a deep foundation pit slope protection structure. Background technique [0002] In the deep foundation pit excavation project, in order to ensure the safety of the construction of the underground structure of the foundation pit and the surrounding environment of the foundation pit, it is necessary to adopt reinforcement and protection measures for the side wall (slope) of the foundation pit. [0003] In the existing slope protection structure, the protective net is usually fixed on the slope of the foundation pit to be protected, so that the soil on the protective slope will not be scattered randomly, or only move in the protective net, so as to achieve the protection foundation. The purpose of pit operator safety. However, for a long time, when there is a lot of scattered soil on the slope, the pressure of the protective net will increase, which will easily ca...
