Description

Technical Field

[0001] This invention relates to the field of building construction, and more specifically, to a support device for high-stress composite ring beams and its construction method. Background Technology

[0002] During the construction of tunnels, in order to ensure the structural stability and safety of the internal beams, it is necessary to use support devices to support and protect the inner surface to prevent collapse and spalling.

[0003] However, existing ring beam support devices are mostly simple combinations of concrete slabs to form an arc structure, which is then laid on the inner surface of the roadway. In order to ensure the stability of the combination, anchor bolts are often pre-drilled inside the roadway and embedded, and then the guard plates are positioned and connected. Such construction structures are prone to misalignment and interference during operation, affecting efficient and precise construction and the stability of the combination. Furthermore, when the guard plates are combined, it is not easy to fix them at the separate positions, resulting in poor stability. Improvements are needed. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a high-stress combined ring beam support device and its construction method. The device combines vertical and arc-shaped guard plates to fit the roadway surface, facilitating close-fitting installation. Furthermore, the pre-reserved threaded cylinder structure allows for the formation of anchor bolt structures during assembly and drilling, preventing misalignment and interference. This facilitates overall alignment and fixed assembly, resulting in convenience and efficiency. Simultaneously, the combination notch at the joint line connects the combined plates, promoting alignment and stability. This significantly improves usability and stability, ensuring safe and efficient precise alignment support.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A support device for high-stress composite ring beams and its construction method are disclosed, comprising a base, a channel on the surface of the base, a vertical guard plate fixedly installed on the side of the channel, an arc-shaped guard plate fixedly connected to one end of the vertical guard plate, the surface of the arc-shaped guard plate fixedly connected to one end of the channel, threaded cylinders on the surfaces of both the vertical guard plate and the arc-shaped guard plate, a connecting hole on the surface of the base, one end of the connecting hole abutting against one side of the threaded cylinder, a casting hole on the other end of the connecting hole located inside the base, a positioning tube fixedly inserted inside the connecting hole, one end of the positioning tube connected to the center of the threaded hole, a side through hole on the other end of the positioning tube, the surface of the side through hole fixedly inserted into the side of the casting hole, a concrete layer fixedly poured into the side of the casting hole, and the concrete layer fixedly filling the side of the positioning tube.

[0007] A construction method for a high-stress composite ring beam support device includes the following steps:

[0008] S1. According to the design dimensions, excavate a channel inside the foundation to form a support structure, and measure the actual dimensions to form a support drawing.

[0009] S2. According to the support drawings, precast concrete is used to form vertical and curved protective plates, which are then transported to the construction site after being cured to meet the requirements.

[0010] S3. Combine and splice the vertical guard plate and the arc guard plate, attach them to the inner wall surface of the passage, and use a frame for reinforcement and support;

[0011] S4. Fix the combined plate into the inside of the combined notch, and splice the guard plates together to form an integral structure;

[0012] S5. Drill a hole in the hole connecting the threaded cylinder to form a connecting hole on the surface of the base material, and then drill another hole to form a casting hole. This allows for direct alignment without interference.

[0013] S6. Wipe the positioning tube into the connection hole and the pouring hole, and then connect the threaded sleeve to the inside of the connecting threaded sleeve.

[0014] S7. Pour concrete from the inside of the positioning tube to fill the positioning tube and the pouring hole, and let it solidify to form a concrete layer for positioning and connection.

[0015] S8. Connect the support ring to the connecting surface, and finally install the fixing cap for threaded fixation. Remove the support frame to complete the construction.

[0016] Furthermore, a threaded sleeve is threadedly connected to the other end of the connecting threaded cylinder. The side of the threaded sleeve is fixedly sleeved onto one end surface of the positioning tube. The positioning tube is connected through the threaded sleeve, which can support and position the tube, avoid eccentricity and misalignment, and facilitate stability.

[0017] Furthermore, a fixing cap is threaded to one end of the positioning tube, and one side of the fixing cap is tightly connected to one side of the threaded sleeve. The positioning tube can be threaded and fixed through the fixing cap, which facilitates protection.

[0018] Furthermore, a support ring is slidably fitted onto the other side surface of the threaded sleeve. The support ring is located on one side surface of the vertical guard plate. The threaded sleeve is connected to the support ring, which can provide auxiliary support, prevent misalignment, and facilitate stability.

[0019] Furthermore, one side surface of the support ring is provided with an arc-shaped surface, and the surface of the arc-shaped surface is attached to the side of the arc-shaped guard plate.

[0020] Furthermore, a flat surface is provided at the middle position of one side surface of the arc-shaped surface. The surface of the flat surface is tightly connected to the surface of the vertical guard plate. By setting the arc-shaped surface and the flat surface through the support ring, the vertical guard plate and the arc-shaped guard plate can be switched respectively to avoid interference and ensure the stability of the connection.

[0021] Furthermore, both ends of the vertical guard plate and the arc-shaped guard plate are provided with seam lines, and one side surface of the seam line is provided with a combination notch. The combination notch provided by the seam line facilitates assembly and splicing and avoids interference.

[0022] Furthermore, a combination plate is fixedly installed on the side of the combined notch. The two end surfaces of the combination plate are respectively connected to the surfaces of the vertical guard plate and the arc-shaped guard plate. By connecting the combination plate through the combined notch, the two guard plates can be spliced ​​and fixed, which facilitates positioning and installation.

[0023] Furthermore, both ends of the combined plate are threaded with combined screws, and the surface of the combined screws is threaded to both ends of the combined notch. The combined plate is connected by the combined screws, which facilitates positioning and installation and is relatively stable.

[0024] Compared with the prior art, the advantages of this invention are:

[0025] (1) This solution combines vertical guard plates and arc guard plates to fit the roadway surface, which is conducive to close installation. Furthermore, through the reserved connecting threaded cylinder structure, the anchor structure can be formed by drilling and casting during assembly, without misalignment or interference.

[0030] (6) By setting up a combination notch through the seam line, it is easy to combine and splice and avoid interference.

[0031] (7) By connecting the combined plates through the combined notch, the two guard plates can be spliced ​​and fixed, which is convenient for positioning and installation.
