Description

A rectangular caisson internal support operation platform Technical Field

[0001] This utility model relates to the field of caisson technology, specifically to an internal support and operation platform for a rectangular caisson. Background Technology

[0002] A caisson is a cylindrical structure. It is formed by excavating soil inside the caisson, relying on its own weight to overcome the frictional resistance of the caisson wall, and sinking it to the design elevation. Then, the bottom of the caisson is sealed with concrete and the caisson hole is filled, making it the foundation of bridge piers or other structures. The advantages and disadvantages of rectangular caissons are exactly the opposite of those of circular caissons. They can easily match the round or rectangular cross-section of the upper pier body, saving the amount of foundation masonry and excavation, and making fuller use of the bearing capacity of the foundation.

[0003] Chinese utility model patent CN215803087U discloses a safety operation platform for caissons, comprising a platform conforming to the shape of the caisson wall, several annular steel wire ropes connecting the platform's periphery, and several pre-embedded anchoring components evenly distributed around the caisson wall. The pre-embedded anchoring components include anchoring round steel columns fully embedded inside the caisson wall and hanging round steel columns partially embedded inside the caisson wall, forming a "√" shape, with the end of the hanging round steel column extending higher than the caisson wall. The annular steel wire ropes are suspended from the hanging round steel columns of the pre-embedded anchoring components. This utility model simplifies and improves the structural form of the safety operation platform, increases the efficiency of platform manufacturing, has high applicability, and makes the installation and disassembly of the platform easier, thereby improving the overall construction efficiency of the caisson wall; by increasing the coverage area of ​​the safety operation platform, the safety performance of the platform is improved, and the working space for operators is increased.

[0004] However, the following problems were found in the implementation of the relevant technology: poor stability. If the anchor points are not firm enough or the wire rope becomes loose, the safety operation platform may shift or tilt during construction, affecting the stability and safety of the overall structure. In addition, the wire rope itself has a certain degree of elasticity and may elongate and deform when subjected to large tension, thereby reducing its support capacity for the safety operation platform. Summary of the Invention

[0005] This utility model proposes an internal support operating platform for rectangular caissons, which solves the problems of poor stability in related technologies. If the anchor points are not firm enough or the wire ropes become loose, the safety operating platform may shift or tilt during construction, affecting the stability and safety of the overall structure. In addition, the wire ropes themselves have a certain degree of elasticity and may elongate and deform when subjected to large tensile forces, thereby reducing their support capacity for the safety operating platform.

Fasteners are provided near the ends of the first and second support rods, and the other ends of the first and second support rods are connected to each other through the fasteners.

[0008] The interior of the caisson body is equipped with a template, which is located above the first support rod and the second support rod.

[0009] Preferably, the fastener includes a connecting seat, and both sides of the connecting seat are pin-connected to a fixing frame, and the first support rod and the second support rod are located between the connecting seat and the fixing frame;

[0010] A first bolt is inserted into the connecting seat, and a first nut is threaded onto the outer side wall of the first bolt, with the first nut located on one side of the fixing frame.

[0011] Preferably, both the first support rod and the second support rod are provided with a support mechanism.

[0012] Preferably, the support mechanism includes a U-shaped frame that is snapped onto the first support rod and the second support rod, and a support tube is provided on the inner side of the U-shaped frame. Both the U-shaped frame and the support tube are provided with round holes.

[0013] A second bolt is inserted into the connected circular hole, and a second nut is threaded onto the outer wall of the second bolt. The support tube is locked and fixed to the U-shaped frame through the circular hole and the second bolt and the second nut.

[0014] Preferably, the template has multiple pairs of insertion interfaces, and the template is provided with a U-shaped lead screw, both ends of which pass through the insertion interfaces and are threaded to a third nut.

[0015] Preferably, a strip plate is provided on the outer wall of the U-shaped lead screw, and the strip plate is located below the third nut.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The first and second support rods are inserted manually into the PVC sleeves pre-embedded in the caisson body. Then, the other ends of the first and second support rods are connected manually with fasteners. Finally, the template is laid flat on the first and second support rods. This effectively prevents the template from shifting during construction or use, ensuring the overall structure is stable and reliable. It also avoids the tensile deformation problems that may occur with traditional suspension methods, and can better withstand pressure or other loads from above, meeting the strength requirements of different engineering environments.
