Description

Technical Field

[0001] This invention relates to the field of new energy solar power generation engineering technology, and in particular to a PHC pipe pile structure for complex sandy soil layers. Background Technology

[0002] PHC pipe piles are widely used in building foundation engineering due to their high strength, high durability, and ease of construction, especially suitable for projects with high bearing capacity requirements. However, in complex sandy soil environments, the construction and use of PHC pipe piles face many technical challenges, and the limitations of existing pipe pile structures and supporting processes are gradually becoming apparent, mainly in the following aspects: Complex sandy soil layers are characterized by high particle flowability, uneven lateral restraint, and susceptibility to vibration. Existing PHC pipe pile connections mostly rely on simple splicing or a single guiding structure. During the pipe pile docking process, the lack of a precise guiding device often leads to axial deviation, requiring repeated adjustments to complete the docking, which seriously reduces construction efficiency.

[0003] Existing PHC pipe pile structures for complex sandy soil layers, including the "pipe pile body and support rods" to achieve connection work, have the following problems: The connection process is achieved using the pipe pile body and support rods. In this structure, a positioning block is installed inside the fixed cylinder. When the pipe pile body and the docking body are connected, the target flange of the docking body is aligned with the connecting plate. This positioning method requires repeated adjustments to complete the connection, which seriously reduces construction efficiency. In addition, the pipe pile has a certain weight, and when it comes into contact with the positioning block, the positioning block will immediately move downwards, making it difficult for workers to perform accurate connection conveniently. Therefore, this structure needs to be improved. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to propose a PHC pipe pile structure for complex sandy soil layers, which can improve the guiding accuracy and construction efficiency during the PHC pipe pile connection process.

[0005] To achieve the above and other related objectives, the present invention provides a PHC pipe pile structure for complex sandy soil layers, comprising: The first pipe pile has a connecting mechanism at its bottom; The connecting mechanism is surrounded by a hoisting mechanism.

[0006] In one embodiment of the present invention, the connecting mechanism includes: A guide rod is inserted into the bottom of the first pipe pile, and a second pipe pile is fixedly connected to the bottom of the guide rod. The second pipe pile has a first guide frame slidably connected to the outer periphery of its front surface, and a second guide frame slidably connected to the outer periphery of its rear surface. A first guide frame is slidably connected to the bottom periphery of the first pipe pile, and a first fixed shaft is threadedly connected inside the first guide frame; The second guide frame is slidably connected to the bottom periphery of the first pipe pile, and the second guide frame is threadedly connected to a second fixed shaft.

[0007] In one embodiment of the present invention, the connecting mechanism further includes: A pin is inserted into the second pipe pile, and the pin is also inserted into the first pipe pile.

[0008] In one embodiment of the present invention, the inner sides of the first guide frame and the inner sides of the second guide frame are in contact with the outer periphery of the first pipe pile, and are located on the front and rear sides of the first pipe pile, respectively. When the first pipe pile is connected to the second pipe pile, the first guide frame and the second guide frame perform a guiding function.

[0009] In one embodiment of the present invention, the first fixed shaft and the second fixed shaft respectively penetrate through the interior of the second pipe pile.

[0010] In one embodiment of the present invention, two sets of the guide rod, the first guide frame, the first fixed shaft, the second guide frame, and the second fixed shaft are provided, and are respectively located at the top of the second pipe pile and the first pipe pile.

[0011] In one embodiment of the present invention, the hoisting mechanism includes: The lifting ring is threadedly connected to the left and right sides of the second pipe pile, and a connecting plate is slidably connected to the outer periphery of the lifting ring. The connecting plate is threadedly connected to a limit shaft.

[0012] In one embodiment of the present invention, the limiting shaft passes through the interior of the second pipe pile.

[0013] In one embodiment of the present invention, two sets of the lifting ring, connecting plate and limiting shaft are provided, and are respectively located around the second pipe pile and the first pipe pile.

[0014] In one embodiment of the present invention, the two sets of lifting rings, connecting plates and limiting shafts are used to realize the hoisting work of the first pipe pile and the second pipe pile.

[0015] As described above, the PHC pipe pile structure for complex sandy soil layers of the present invention has the following beneficial effects: This invention discloses a PHC pipe pile structure for complex sandy soil layers. Through a connection mechanism, when connecting PHC pipe piles in complex sandy soil layers, the first and second guide frames are slidably connected to the outer periphery of the front and rear surfaces of the second pipe pile, respectively, and fixed by the first and second fixed shafts. Then, external hoisting equipment can be used to slide the first pipe pile onto the inner side of the first and second guide frames, guiding the connection process and improving efficiency. The first pipe pile is inserted around the guide rod. During connection, workers can manually rotate the first pipe pile to improve connection accuracy, ensuring the bottom contacts the top of the second pipe pile. After connection, pins are inserted into the first and second pipe piles, completing the connection. After connection, the first and second guide frames can be disassembled, effectively preventing loosening of the connection due to soil displacement and vibration in complex sandy soil layers, significantly improving vertical bearing capacity and pull-out resistance, and enhancing overall construction quality.

[0016] The present invention provides a PHC pipe pile structure for complex sandy soil layers. Through the set hoisting mechanism, the hoisting rings are fixed to both sides of the pipe pile by threaded connection. It can be flexibly disassembled and assembled according to construction needs, which not only meets the needs of different construction stages such as pipe pile transportation and hoisting, but also avoids the interference of traditional fixed hoisting structures on the subsequent use of pipe piles.

[0017] The present invention provides a PHC pipe pile structure for complex sandy soil layers. The connecting plate is locked to the pipe pile by a limiting shaft, and the limiting shaft penetrates the inside of the pipe pile, which further ensures the stability of the lifting ring during operation and can effectively prevent the lifting ring from loosening or falling off during the hoisting process, thus avoiding safety accidents such as pipe pile tilting or falling.

This allows the first guide frame 24 and the second guide frame 26 to play a guiding role when the first pipe pile 1 is connected to the second pipe pile 22, thereby improving the accuracy and efficiency of the connection.

[0039] In one embodiment of the present invention, the first fixed shaft 25 and the second fixed shaft 27 respectively pass through the interior of the second pipe pile 22, so as to ensure the stability of the first guide frame 24 and the second guide frame 26 through the first fixed shaft 25 and the second fixed shaft 27.

[0047] In one embodiment of the present invention, the PHC pipe pile structure for complex sandy soil layers of the present invention, in actual operation, when this device is used, when it is necessary to connect the PHC pipe pile for complex sandy soil layers, and after the second pipe pile 22 is installed and the top is exposed, firstly, the first guide frame 24 and the second guide frame 26 are slidably connected to the outer periphery of the front and rear surfaces of the second pipe pile 22 respectively, and fixed by the first fixed shaft 25 and the second fixed shaft 27 to ensure the stability of the first guide frame 24 and the second guide frame 26.

[0048] In one embodiment of the present invention, the connecting plate 32 is first slidably connected to the periphery of the lifting ring 31, and the lifting ring 31 is fixed to both sides of the first pipe pile 1 by threaded connection. It can be flexibly disassembled and assembled according to construction needs, which not only adapts to the needs of different construction stages such as pipe pile transportation and hoisting, but also avoids the interference of traditional fixed hoisting structure on the subsequent use of pipe pile. After the lifting ring 31 is fixed, the connecting plate 32 and the pipe pile can be threadedly locked by the limiting shaft 33, which further ensures the stability of the lifting ring 31 during operation and can effectively prevent the lifting ring 31 from loosening or falling off during hoisting, and avoid safety accidents such as pipe pile tilting or falling.

[0049] In one embodiment of the present invention, the first pipe pile 1 is slidably connected to the inner side of the first guide frame 24 and the second guide frame 26 by external hoisting equipment, which plays a guiding role in the connection process of the first pipe pile 1 and the second pipe pile 22. It can guide the first pipe pile 1 and the second pipe pile 22 to quickly align, avoiding repeated adjustments caused by positioning deviations in traditional pipe pile connections, thus improving the connection efficiency.

At this time, the first pipe pile can be slidably connected to the inner side of the first guide frame and the second guide frame by external hoisting equipment, which plays a guiding role in the connection process of the first pipe pile and the second pipe pile, improving the connection efficiency, and allowing the first pipe pile to be inserted into the outer periphery of the guide rod. During the connection, the position of the first pipe pile can be manually rotated by the workers to improve the connection accuracy, and the bottom of the first pipe pile contacts the top of the second pipe pile. After the connection is completed, the pins can be inserted into the inside of the first pipe pile and the second pipe pile, and the connection work can be realized. After the connection is completed, the first guide frame and the second guide frame can be disassembled, effectively avoiding the connection loosening of the pipe pile due to soil lateral displacement and vibration in complex sandy soil layers, greatly improving the vertical bearing capacity and pull-out performance, and improving the overall construction quality. The lifting mechanism features lifting rings that are threadedly fixed to both sides of the pipe pile. These rings can be flexibly assembled and disassembled according to construction needs, adapting to different construction stages such as pipe pile transportation and lifting, while avoiding interference from traditional fixed lifting structures for subsequent use of the pipe pile. The connecting plate is threadedly locked to the pipe pile via a limiting shaft that penetrates the interior of the pipe pile, further ensuring the stability of the lifting rings during operation. This effectively prevents the lifting rings from loosening or falling off during lifting, avoiding safety accidents such as pipe pile tilting or falling.
