Description

Technical Field

[0001] This utility model relates to the field of soft soil foundation reinforcement technology, specifically a building service foundation reinforcement structure. Background Technology

[0002] Soft foundations are mainly composed of silt, silty soil, fill, miscellaneous fill, or other highly compressible soil layers. Soft foundations are characterized by high water content, high compressibility, and low strength, which can easily lead to large and uneven settlement of buildings.

[0003] A search revealed that patent application number 202320371643.1 discloses a soft foundation reinforcement structure, including a foundation body, with multiple reinforcing ground nails fixedly installed inside the foundation body, and a drainage and grouting mechanism for draining the foundation body while facilitating grouting; the drainage and grouting mechanism is located on one side of the reinforcing ground nails, and includes a reinforcement component located on one side of the reinforcing ground nails;

[0004] Although this soft soil foundation reinforcement structure improves reinforcement efficiency by driving reinforcement nails and pipes into the ground and leaving one side of the pipes protruding from the foundation surface to facilitate water drainage, and then injecting grout through high-pressure grouting pipes, with the grout extending into the foundation through flow holes, the structure has poor positioning of the reinforcement pipes. During grouting, the high-pressure injected concrete generates a strong impact force, which can easily cause the reinforcement pipes to shift, leading to problems such as grouting range deviation and uneven reinforcement. This can not only weaken the overall structural stability and increase subsequent repair costs, but also delay the construction period and create safety hazards, failing to meet the stringent requirements of modern engineering for construction precision and quality control.

[0005] Therefore, we propose a building service foundation reinforcement structure. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a building service foundation reinforcement structure, which solves the problem that the existing device has a poor limiting effect on the reinforcement pipe. During grouting, the reinforcement pipe is subjected to the impact of concrete, and its position is easy to shift, thus affecting the subsequent project.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a building service foundation reinforcement structure, comprising a square and hollow reinforcement pipe, wherein ground nails are fixedly installed on the bottom surface of the reinforcement pipe;

[0008] The four side walls on the outer surface of the reinforcing pipe are provided with protruding ridges in the middle, and the four side walls on the outer surface of the reinforcing pipe are provided with threaded holes arranged in a linear array in the middle. The side walls of the protruding ridges are provided with rectangular grooves that communicate with the threaded holes. The reinforcing pipe is provided with a limit component inside. The four side walls on the outer surface of the reinforcing pipe are provided with slurry discharge holes arranged in a linear array on the left and right sides.

[0009] The limiting component includes a rotating rod disposed inside the reinforcing tube. The bottom end of the rotating rod is rotatably mounted on the center of the top surface of the ground nail via a bearing ring. A first bevel gear, arranged in a linear array and corresponding one-to-one with the position and number of threaded holes, is fixedly fitted on the outer surface of the rotating rod. A threaded rod is threadedly fitted inside the threaded hole. A second bevel gear, meshing with the first bevel gear, is fixedly installed at the end of the threaded rod near the rotating rod. The end of the threaded rod away from the rotating rod is flush with the side of the convex ridge away from the reinforcing tube. A slider threadedly fitted on the outer surface of the threaded rod is slidably fitted inside the rectangular groove. Limiting pins are fixedly installed at the four corners of the slider on the side away from the rotating rod.

[0010] Preferably, the limiting pin and the slider are integrally formed, and the reinforcing tube and the protruding ridge are integrally formed. The integrally formed structure has no splicing or assembly interface, the overall structure is more continuous and complete, can distribute stress more evenly, reduce stress concentration, and thus improve the strength and stability of the structure.

[0011] Preferably, a horizontal plate is fixedly installed at the top of the inner wall of the reinforcing pipe, and the top of the rotating rod is rotatably fitted into the middle of the horizontal plate through a bearing ring, so as to support the top of the rotating rod through the horizontal plate.

[0012] Preferably, a handwheel is fixedly installed on the top surface of the rotating rod, wherein the rotating rod is easily rotated by means of the handwheel.

[0013] Preferably, a support plate is fixedly fitted at the top of the outer surface of the reinforcing pipe, and the top surface of the support plate is flush with the top surface of the reinforcing pipe. The support plate can support the reinforcing pipe by contacting the surface of the foundation, thus preventing the reinforcing pipe from sinking.

[0014] This utility model provides a foundation reinforcement structure for building services. It has the following beneficial effects:

[0015] This building service foundation reinforcement structure uses a handwheel to drive a rotating rod and a first bevel gear to rotate. The meshing of the first and second bevel gears allows the threaded rod to rotate inside the threaded hole, causing a slider to move along the inner wall of a rectangular groove. The slider pushes a limiting pin into the foundation, thus limiting the position of the reinforcement pipe. Furthermore, the support plate, in contact with the foundation surface, supports the reinforcement pipe, preventing it from sinking. This achieves efficient positioning of the reinforcement pipe, preventing displacement during grouting and improving project safety and quality. It also solves the problem of existing devices having poor positioning performance for reinforcement pipes, which can easily shift the pipe's position during grouting due to the impact of concrete, thus affecting subsequent work.
