Description

Technical Field

[0001] This utility model relates to the field of foundation pit pile support technology, and in particular to a soil reinforcement structure between foundation pit pile support piles. Background Technology

[0002] With urban development, the development and utilization of underground space is increasing, and foundation pit projects are everywhere. As a form of foundation pit support, pile support has the advantages of high support rigidity, small space occupation, and mature construction technology. Furthermore, combined with anchor bolts, soil nails, internal bracing, jet grouting piles, and mixing piles, the application range of pile support is becoming more extensive.

[0003] Foundation pit projects vary in size, and foundation pit support piles are mostly installed in an equidistant arrangement. However, at the connection point at the installation end, the installation distance may vary. Existing foundation pit pile support soil reinforcement structures are not easy to adjust, resulting in poor soil reinforcement effect. Furthermore, at the installation end, the soil reinforcement structure needs to be processed again to accommodate different installation gaps, which reduces work efficiency. Therefore, we propose a foundation pit pile support soil reinforcement structure. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology. The scale of foundation pit projects varies, and the foundation pit support piles are mostly installed in an equidistant arrangement. However, the installation distance may be uneven at the connection point at the end of the installation. The existing soil reinforcement structure between foundation pit pile support piles is not easy to adjust, resulting in poor reinforcement effect on the soil layer. Furthermore, the soil reinforcement structure needs to be processed again at the end of the installation to meet different installation gaps, which reduces work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A soil reinforcement structure between piles for foundation pit support includes a main body of support piles, and several adjustment mechanisms are equidistantly arranged between two main bodies of support piles from top to bottom.

[0007] The adjustment mechanism includes a reinforcing plate, with sleeves symmetrically arranged at the top and bottom of the reinforcing plate.

[0008] As a preferred embodiment of this utility model, a slot is provided on the inner side of the support pile body, and the reinforcing plate is adapted to the slot.

[0009] The technical effect of adopting the above-mentioned further solution is that the reinforcing plate can be inserted into the slot by matching the reinforcing plate with the slot, thereby improving the fixing effect of the reinforcing plate. At the same time, the reinforcing plate can also be adjusted according to the installation gap, thereby improving the installation efficiency.

[0010] As a preferred embodiment of this utility model, the top end of the reinforcing plate has a threaded opening corresponding to the second threaded rod, and the second threaded rod is adapted to the threaded opening.

[0011] The technical effect of adopting the above-mentioned further solution is that the height of the reinforcing plate can be adjusted by rotating the second threaded rod, so that the reinforcement can be better carried out according to the actual situation of the soil layer and the reinforcement effect of the soil layer can be improved.

[0012] As a preferred embodiment of this utility model, a limiting groove is provided at the bottom of the reinforcing plate corresponding to the limiting rod, and the limiting rod is adapted to the limiting groove.

[0013] The technical effect of adopting the above-mentioned further solution is that by matching the limiting rod with the limiting groove, the reinforcing plate can be limited to prevent it from shifting, and the second threaded rod can better reinforce the soil layer.

[0014] In a preferred embodiment of this utility model, the fixing rod is slidably connected to the sleeve, and the fixing rod is fixed to the main body of the support pile by bolts.

[0015] The technical advantage of adopting the above-mentioned further solution is that, through the sliding connection between the fixed rod and the sleeve, the distance between the main bodies of the support piles can be adjusted, thereby improving the practicality of the adjustment mechanism and the overall working efficiency.

[0016] As a preferred embodiment of this utility model, the first threaded rod is adapted to the sleeve, and the first threaded rod is adapted to the fixing groove.

[0017] The technical effect of adopting the above-mentioned further solution is that by rotating the first threaded rod, it can be inserted into the fixing groove, thereby cooperating with the sleeve to clamp and fix the fixing rod, improving the stability of use.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0028] Example 1

[0029] like Figure 1-3 As shown, this utility model provides a technical solution: a soil reinforcement structure between piles for foundation pit pile support, including a support pile body 1, and several adjustment mechanisms 2 are equidistantly arranged from top to bottom between two support pile bodies 1. The adjustment mechanism 2 includes a reinforcement plate 201, and sleeves 202 are symmetrically arranged at the top and bottom of the reinforcement plate 201. Fixing rods 203 are symmetrically arranged inside the sleeves 202 near the left and right sides. Fixing grooves 204 are opened on the front of the fixing rods 203. First threaded rods 205 are symmetrically arranged on the front of the sleeves 202 near the left and right sides. A second threaded rod 206 is arranged through the bottom of the top of the sleeve 202 near the top. A limit rod 207 is arranged at the top of the sleeve 202 near the bottom.

[0030] Example 2

[0031] like Figure 1-3 As shown, a slot 101 is provided on the inner side of the main body 1 of the support pile. The reinforcing plate 201 is adapted to the slot 101. By adapting the reinforcing plate 201 to the slot 101, the reinforcing plate 201 can be inserted into the slot 101, thereby improving the fixing effect of the reinforcing plate 201. At the same time, the reinforcing plate 201 can also be adjusted according to the installation gap, improving the installation efficiency. The top of the reinforcing plate 201 is provided with a threaded opening 2011 corresponding to the second threaded rod 206. The second threaded rod 206 is adapted to the threaded opening 2011. By rotating the second threaded rod 206, the height of the reinforcing plate 201 can be adjusted, so as to better reinforce according to the actual situation of the soil layer and improve the reinforcement effect of the soil layer. The bottom of the reinforcing plate 201 is provided with a limiting groove 2012 corresponding to the limiting rod 207. The limiting rod 207 and the limiting groove 2012 are connected to the limiting rod 207. The positioning groove 2012 is adapted to the positioning rod 207, which is adapted to the positioning groove 2012 to limit the reinforcement plate 201 and prevent it from shifting. The second threaded rod 206 can better reinforce the soil layer. The fixing rod 203 is slidably connected to the sleeve 202. The fixing rod 203 is fixed to the support pile body 1 by bolts. The sliding connection between the fixing rod 203 and the sleeve 202 can be adjusted according to the distance between the support pile bodies 1, improving the practicality of the adjustment mechanism 2 and the overall working efficiency. The first threaded rod 205 is adapted to the sleeve 202 and the fixing groove 204. By rotating the first threaded rod 205, it can be inserted into the fixing groove 204, thereby clamping and fixing the fixing rod 203 with the sleeve 202, improving the stability of use.

[0032] The workflow of this utility model is as follows: When adjusting the installation of a soil reinforcement structure for foundation pit pile support, firstly, insert both ends of the reinforcement plate 201, which is located at the top of the support pile body 1, into the slot 101 and slide it downwards. After sliding to the expected installation position, pull out the fixing rods 203 at both ends of the sleeve 202 and fix the fixing rods 203 to the surface of the support pile body 1 with bolts to complete the initial installation. Subsequently, according to the depth of the foundation pit and the height of the support pile body 1, install multiple adjustment mechanisms 2 at equal intervals in sequence following the above steps. When it is necessary to perform targeted micro-adjustment in areas where the soil layer is relatively loose, During reinforcement, the second threaded rod 206 can be rotated to disengage it from the threaded opening 2011, and the reinforcement plate 201 can be lifted or lowered, allowing the reinforcement plate 201 to move up and down under the restriction of the limiting rod 207. After moving to the required position, the second threaded rod 206 can be rotated to re-enter the threaded opening 2011, completing the positioning of the reinforcement plate 201. This effectively improves the reinforcement effect of the soil layer. At the same time, based on the dimensions of the slot 101 and the fixing plate, the gap between the support pile body 1 and the foundation pit can be calculated before the support pile body 1 is poured, according to the actual perimeter of the foundation pit, to prevent secondary processing and effectively improve work efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
