Description

Technical Field

[0001] The utility model relates to the technical field of reinforcement structures, in particular to a soil nail wall reinforcement structure. Background Art

[0002] Soil nail wall is a form of soil reinforcement. The general practice is to insert soil nails into the slope of the foundation pit and inject concrete into the soil nail holes to fix the soil nails. A layer of steel mesh is laid on the slope and the steel mesh is fixed to the ends of the soil nails outside the slope. A layer of concrete surface is then sprayed on the steel mesh to combine it with the slope to achieve slope reinforcement.

[0003] Among them, it was found through search that the utility model patent with patent application number CN202022381342.6 discloses a reinforced soil nail wall support structure, including a foundation pit slope, soil nails are installed inside the foundation pit slope, and the inner wall of the soil nails is connected to a reinforcement mechanism, the interior of the reinforcement mechanism includes a drill rod, and an arc block is fixedly installed on one side of the drill rod, the outer wall of the drill rod is provided with a spring, and a slot is installed on the outside of the drill rod, and the inner wall of the arc block is movably connected with a plug rod.

[0004] When the structure is in use, the insertion rod is inserted into the soil nail, so that the insertion rod squeezes the arc block inside the soil nail. Under the elastic action of the spring, the arc block drives the drill rod to move through the slot toward the outer wall of the soil nail, so that the drill rod and the soil nail are at a vertical angle to reinforce the soil nail. Through such an arrangement, the contact area between the soil nail and the soil is increased, thereby improving the composite force bearing capacity of the soil nail, the soil and cement slurry, increasing the soil's holding capacity to the soil nail, and improving the stability of the composite soil. However, the structure is not easy to limit the fixed position when in use, resulting in the synchronous deformation of the local area when the soil is deformed, resulting in low stability of the reinforcement. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a soil nail wall reinforcement structure, aiming to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil nail wall reinforcement structure, comprising a support plate for support, and a positioning reinforcement component is arranged on the support plate.

[0007] The positioning and reinforcement assembly includes a support plate arranged on a support plate for support, one side of the support plate is rotatably connected with a plurality of first positioning threaded cylinders for limiting, and each of the first positioning threaded cylinders is threadedly connected with a first limiting column for positioning, and the first limiting column is slidably connected to the support plate.

[0008] A pressure arm is arranged on the top of the support plate, and a shaft pin is rotatably connected to the pressure arm, extending to the support plate and rotatably connected to the support plate.

[0009] It can be seen that in the above technical solution, the first positioning threaded barrel is rotated so that the first limiting column can be adjusted on the first positioning threaded barrel, so that the first limiting column can extend from the first positioning threaded barrel to the wall for fixation.

[0010] Optionally, in a possible embodiment, one end of the pressure arm is rotatably connected to a connecting piece, the bottom of the connecting piece extends to the support plate and is rotatably connected to the support plate, one end of the connecting piece is provided with a pressure plate, and a second positioning threaded cylinder for positioning is provided on the pressure plate, a second limiting column is provided inside the second positioning threaded cylinder, the second limiting column is threadedly connected to the second positioning threaded cylinder, a docking card is provided on the pressure plate, a limiting threaded rod is provided on the docking card, the bottom of the limiting threaded rod extends to the bottom of the pressure plate, one end of the docking card extends to the connecting piece and is fixedly connected to the connecting piece, and an external support is provided at one end of the pressure arm, and the external support is detachably connected to the pressure arm.

[0011] It can be seen that in the above technical solution, the docking card drives the pressure plate, the second positioning threaded cylinder and the second limit column to move, so that the second limit column can be inserted into the wall for reinforcement, and when the connecting member and the pressure plate are flipped, the connecting member will rotate along the axis point of the connection between the connecting member and the support plate, which is easy to flip the pressure plate, and the shaft pin can position the pressure arm and the pressure plate when flipping, so as to ensure the stability of the pressure plate when flipping.

[0012] The utility model has the following advantages:

[0013] By providing a positioning and reinforcement component, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the first positioning threaded barrel can be rotated to allow the first limiting column to be adjusted on the first positioning threaded barrel, so that the first limiting column can extend from the first positioning threaded barrel to the wall for fixation.

[0014] And the pressing plate, the second positioning threaded cylinder and the second limiting column are driven to move by the docking clamping plate, so that the second limiting column can be inserted into the wall surface for reinforcement.

[0015] When the connecting member and the pressure plate are flipped, the connecting member will rotate along the axis point of the connection between the connecting member and the support plate, which makes it easy to flip the pressure plate. The axle pin can position the pressure arm and the pressure plate when they are flipped to ensure the stability of the pressure plate when it is flipped, and avoid the phenomenon that the local area will be deformed synchronously when the soil is deformed, so as to ensure the stability of the reinforcement.
