[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figure 1 The diagram shows a working platform for testing high-cantilever, large-spacing foundation piles. The platform includes a first platform support and a second platform support respectively installed on two prestressed concrete pipe piles, and a platform body installed between the first platform support and the second platform support.
[0025] like Figure 1 and Figure 2 As shown, both the first platform support and the second platform support include a clamp 1 and a fixing member 2 threadedly connected to the clamp 1; the clamp 1 includes an arc-shaped clamp body and two clamp fixing parts disposed at both ends of the clamp body; the clamp fixing parts are provided with threads; the clamp fixing parts are connected to the fixing member 2 by nuts 3.
[0026] In the above technical solution, the arc-shaped clamp body is designed to fit the circular outer surface of the prestressed concrete pipe pile 7, allowing the clamp 1 to tightly wrap around the pile, increasing the contact area, dispersing pressure, and improving the stability of the clamping. The clamp fixing part is threaded for easy engagement with a nut to achieve tightness adjustment. The fixing part 2 is connected to the clamp fixing part via a nut 3; this threaded connection allows adjustment of the tightness between the fixing part and the clamp by rotating the nut 3. During installation, the fixing part 2 can be tightly fixed to the clamp 1 as needed, thus stably installing it on the pile and providing a stable support foundation for the entire platform. Preferably, the fixing part 2 is made of channel steel, which has good bending strength and load-bearing capacity, capable of withstanding various loads transmitted from the platform body and ensuring the stability of the platform.
[0027] As a further improvement to the above technical solution, such as Figure 1 As shown, the platform body includes a platform frame and a panel 6 mounted on the platform frame. Figure 4 As shown, the platform frame is a truss structure formed by multiple steel pipes 4. The platform frame includes two parallel first steel pipes and multiple parallel second steel pipes; the first and second steel pipes are perpendicular to each other, and this crisscrossing structure forms a stable frame system. The first and second steel pipes are collectively referred to as steel pipes, and are indicated by the number 4 in the attached drawing. The first steel pipes mainly bear tensile and compressive forces along their length, while the second steel pipes provide lateral support and enhance overall stability. Together, they effectively distribute the load on the platform and improve its load-bearing capacity.
[0028] As a further improvement to the above technical solution, such as Figure 4 As shown, the first steel pipe is connected to the second steel pipe via a right-angle coupler 5. The design of the right-angle coupler 5 allows for a convenient and quick, secure connection between mutually perpendicular steel pipes. The right-angle coupler 5 ensures that the angle between the steel pipes 4 is fixed at 90 degrees, guaranteeing the regularity and stability of the frame structure and facilitating construction, installation, and disassembly.
[0029] As a further improvement to the above technical solution, such as Figure 3 As shown, the fixing component 2 is equipped with a steel pipe limiter; the steel pipe limiter includes two symmetrically arranged limit members 8; the limit members 8 are connected to the fixing component 2 by bolts 9; the area between the two limit members 8 of the steel pipe limiter is used to clamp and fix the first steel pipe. Preferably, the bolts 9 are high-strength bolts. The limit members 8 are made of angle steel, which has a certain rigidity and strength, and can provide a reliable limiting function. The two limit members 8 are symmetrically arranged, and the middle area is used to clamp and fix the first steel pipe. The connection by the high-strength bolts 9 can ensure the firmness of the connection, prevent the limit members from loosening during use, ensure the position of the first steel pipe is fixed, and thus stabilize the entire platform frame. The fixing component 2 has a first adjustment hole, and the limit members 8 have a second adjustment hole. By cooperating with the adjustment holes and the bolts 9, the distance between the limit members can be adjusted to accommodate first steel pipes of different diameters, improving the versatility and adaptability of the device.
[0030] As a further improvement to the above technical solution, such as Figure 5 As shown, the panel 6 includes a panel frame and a wire mesh mounted on the panel frame; hooks are provided at both ends of the panel frame. The panel frame serves to support and fix the wire mesh, and also connects to the platform frame to transfer loads. The wire mesh is lightweight, high-strength, and non-slip, meeting the safety requirements of inspection personnel working on the platform while reducing the overall weight of the platform. The hooks at both ends of the panel frame facilitate quick and accurate installation of the panel onto the platform frame, improving installation efficiency, and also ensuring the stability of the panel on the platform frame to a certain extent, preventing displacement of the panel during use.
[0031] The installation process of this utility model is as follows:
[0032] (1) At a distance of 1.0m to 1.5m from the top of the foundation pile 7, the clamp 1 is wrapped around the foundation pile 7, and the fastener 2 and the clamp 1 are tightly connected by the nut 3. The center point of the fastener 2 is located on the line connecting the centers of the two foundation piles 7. The fasteners are installed symmetrically on the two foundation piles 7 respectively. At this time, the platform support is completed.
[0033] (2) Connect the limiting part 8 and the fixing part 2 with high-strength bolts 9. At this time, the steel pipe limiter is completed.
[0034] (3) Use right-angle fastener 5 to fasten the first steel pipe and the second steel pipe to form the platform frame. At this time, the platform frame is completed.
[0035] (4) Place the platform frame made in step (3) symmetrically in the steel pipe limiter on the upper part of the fixing part 2, and place the panel 6 symmetrically on the platform frame. The installation is now complete.
[0036] This utility model relates to a working platform for testing high-cantilever, large-spacing foundation piles. "High-cantilever" refers to the pile top elevation being more than 2 meters above the ground, and "large-spacing" means the center-to-center distance between piles is greater than 10 times the pile diameter. Figure 1 As shown, at a distance of 1.0m to 1.5m from the top of pile 7, a clamp 1 is wrapped around pile 7. The fixing member 2 and clamp 1 are tightly connected by nuts 3. One clamp 1 and one fixing member 2 are symmetrically installed on each of the two piles 7. This invention uses clamps to wrap around the piles and nuts to tightly connect the fixing member and clamp, providing a rigid platform support and ensuring the platform's safety and stability. A limiting member 8 and fixing member 2 are connected by high-strength bolts 9 to form a steel pipe limiter. Then, right-angle fasteners 5 are used to fasten the first and second steel pipes, forming a platform frame. The two ends of the platform frame are respectively installed in the fixing member on the first horizontal support and the steel pipe limiter on the second horizontal support. Finally, the panel 6 is placed on the platform frame to ensure uniform force distribution. This invention effectively solves the problem of difficult pile testing operations and improves work efficiency.
[0037] The various components of the high-cantilever, large-spacing pile testing work platform described in this utility model are mostly connected using bolts, nuts, and fasteners. Compared to traditional welding and other fixing methods, the installation process is simpler and faster, eliminating the need for specialized welding equipment and technicians, significantly shortening installation time and improving work efficiency. The clamps are connected to the fixing components with nuts, the steel pipes are connected with right-angle fasteners, and the panels are installed on the platform frame using hooks, all reflecting this convenient installation design concept. Through a reasonable structural design, such as the fit between the clamps and the piles, the use of channel steel as fixing components, the longitudinal and transverse steel pipe structure of the platform frame, and the setting of steel pipe limiters, this utility model improves the overall stability and load-bearing capacity of the platform. Compared to traditional scaffolding methods, this platform structure is more stable and can better adapt to the complex environment of high-cantilever, large-spacing pile testing, ensuring the safety of the testing work. The adjustment hole design on the steel pipe limiters can accommodate steel pipes of different diameters, allowing the platform to be flexibly applied in different engineering scenarios. This design takes into account the different specifications of materials that may be encountered in actual engineering, improving the versatility of the device and reducing the operating cost of the equipment.

Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
