[0029] Example:

[0030] like Figures 1 to 8As shown, a slope foundation pit support structure includes a support assembly 1 and a support fixing assembly 2. Several groups of support assemblies 1 are connected as a whole through the support fixing assembly 2 and are arranged on the slope of the foundation pit to prevent the slope from collapsing; the support assembly 1 includes a connecting rod 11, a connecting rod 2 12 and a support member 13. The support member 13 is arranged between the connecting rod 11 and the connecting rod 2 12 to cover the slope. Several fixing members 14 are evenly arranged on the support member 13 to temporarily fix the support member 13 on the slope of the foundation pit. The connecting rods 11 of adjacent support assemblies 1 are connected to each other, and the connecting rods 12 are connected to each other. Interconnected; the support and fixing assembly 2 includes a horizontal plate 1 21, a horizontal plate 22 and a fixing piece 25, the horizontal plate 1 21 is connected to the connecting rod 11, the horizontal plate 22 is connected to the connecting rod 2 12, and the length direction of the horizontal plate 1 21 is parallel to the length direction of the connecting rod 11, the length direction of the horizontal plate 22 is parallel to the length direction of the connecting rod 2 12, a slot 211 is provided on the horizontal plate 1 21, and a clip 221 is provided on the horizontal plate 22 corresponding to the slot 211, the slots 211 and the clip strips 221 of the horizontal plates 1 21 and the horizontal plates 22 adjacent to each other on the slope can be connected to each other, and are connected to the foundation pit slope through the fixing piece 25.

[0031] In this embodiment, the support member 13 includes a plurality of transverse steel wires 131 and a plurality of vertical steel wires 132. The plurality of transverse steel wires 131 and the plurality of vertical steel wires 132 are vertically connected to each other to form a mesh structure. Preferably, the mesh size of the mesh structure is consistent, and the two ends of the vertical steel wire 132 are respectively connected to the connecting rod 11 and the connecting rod 2 12. The two ends of the transverse steel wire 131 extend a distance from the vertical steel wire 132 at the edge, and are used to be connected to the adjacent transverse steel wire 131 through a wire clamp. The wire clamp can be selected from the commonly used wire clamps on the market according to the diameter of the steel wire, which is convenient for connection. In addition, the transverse steel wire 131 and the vertical steel wire 132 are both flexible and can be wound into rolls for easy removal and storage. At the same time, they are suitable for slope support of different slopes, which improves practicality.

[0032] In this embodiment, the fixing member 14 includes a pressure plate 141 and a connecting nail 142. A limiting groove 143 is provided on the side of the pressure plate 141 close to the support member 13.

A threaded column 151 is provided at the rod end on one side of the first limiting plate 15, and a threaded sleeve 17 is slidably provided at the rod end on one side of the second limiting plate 16. The threaded columns 151 and the threaded sleeves 17 of adjacent support assemblies 1 can be threadedly connected. By changing the length of the threaded connection between the threaded column 151 and the threaded sleeve 17, the distance between the left and right adjacent support structures can be adjusted to avoid the support on both sides of the slope being affected by the coverage area of ​​the support member 13 itself, resulting in blank support positions. Without changing the number of groups of support structures used, the area of ​​the slope covered by the overall support can be adjusted, thereby improving the practicality and economy of the device.

[0034] In this embodiment, a plurality of connecting sleeves 23 are provided on the horizontal plate 21, and the connecting sleeves 23 are rotatably sleeved on the connecting rod 11; a plurality of connecting sleeves 24 are provided on the horizontal plate 22, and the connecting sleeves 24 are rotatably sleeved on the connecting rod 2 12, so as to facilitate the support of different slope angles.

When the card slot 211 and the card strip 221 are engaged, the nail holes 1 212 and the nail holes 2 222 coincide with each other, and fixing parts 25 are inserted into the nail holes 1 212 and the nail holes 2 222 to temporarily fix the cross plates 1 21 and 22 on the slope, thereby improving the stability of the support.

[0036] In this embodiment, the second fixing member 25 includes a fixing frame 251 and a second connecting nail 253. The fixing frame 251 is set to be U-shaped and is used to be clamped on both sides of the horizontal plate 1 21 and the horizontal plate 22 to avoid detachment. Conical teeth 252 are set at both ends of the fixing frame 251 to facilitate insertion into the foundation pit slope. The second connecting nail 253 is set on the fixing frame 251 and is used to be inserted into the nail hole 1 212 and the nail hole 222 and connected to the foundation pit slope, thereby improving the safety of the support.

[0037] The working principle of this slope foundation pit support structure is as follows: when in use, unfold the support parts 13 of one group of support structures, rotate the connecting cross plate 1 21 through the connecting sleeve 1 23, and place the cross plate 1 21 at the upper end of the slope, insert the fixing part 25 into the nail hole 1 212, and continue to insert it into the interior of the slope to position and fix it, then, take another group of support structures, clamp the clip 221 at the bottom of the cross plate 22 of the first group of support structures into the clip groove 211 of the cross plate 1 21 of this group of support structures, and align the nail hole 1 212 on the cross plate 1 21 with the nail hole 222 on the cross plate 22 one by one, then use the fixing part 25 to penetrate the nail hole 1 212 and the nail hole 222, and insert the fixing part 25 into the interior of the slope to fix the combination, and set multiple groups of support structures along the length direction of the slope. The structure is constructed by aligning the connecting rods 11 and 12 of the left and right adjacent supporting structures, and then threading the threaded sleeve 17 onto the threaded column 151. The distance between the left and right adjacent supporting structures can be adjusted by sliding the threaded sleeve 17 to adjust according to the different lengths of the slope, thereby avoiding empty support at the left and right ends of the slope and improving practicality. The upper limit of the distance between the left and right adjacent supporting structures is related to the length of the threaded sleeve 17. The supporting structures are connected in sequence downward along the height direction of the slope. The horizontal plate 22 of the lowest supporting structure fits the bottom of the slope, and then is fixed to the inside of the slope through the fixing member 2 25 to complete the support assembly. A fixing member 14 can also be set inside the supporting member 13 to strengthen the fixation. The support construction is simple, convenient and fast, thereby improving the efficiency of the support construction.
