Description

Technical Field

[0001] This utility model relates to the field of PC steel pipe pile technology, and in particular to a PC steel pipe pile maintenance device for deep foundation pits in soft soil. Background Technology

[0002] Deep foundation pits in soft soil are deep foundation pit projects implemented in soft soil foundations. Soft soil is rich in a large amount of water and becomes soft and plastic in a non-load-bearing environment or after being damaged by load. PC steel pipe piles are a commonly used support structure in deep foundation pit projects.

[0003] After prolonged use, existing PC steel pipe piles will develop rust on their surface. Existing maintenance devices are unable to remove the rust, resulting in damage to the PC steel pipe piles and increased maintenance costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a PC steel pipe pile maintenance device for deep foundation pits in soft soil.

[0005] This utility model is achieved using the following technical solution: a PC steel pipe pile maintenance device for deep foundation pits in soft soil, comprising a base plate, a liquid storage tank at the top of the base plate, a liquid outlet pipe at the top of the liquid storage tank, a nozzle inside the liquid outlet pipe, an X-shaped fixing block at the top of the base plate, a liquid outlet on the inner wall of the X-shaped fixing block, a connecting plate on the surface of the X-shaped fixing block, a U-shaped fixing block on the surface of the connecting plate, a threaded rod at the top of the U-shaped fixing block, a connecting rod at the top of the threaded rod, a rotating handle inside the connecting rod, and a limit block at the bottom of the threaded rod.

[0006] As a further improvement to the above solution, two liquid storage tanks are provided, with the bottom ends of the two liquid storage tanks fixedly connected to the top end of the base plate, and several liquid outlet pipes are provided, with the bottom ends of the several liquid outlet pipes fixedly connected to the top ends of the two liquid storage tanks.

[0007] The above technical solution, with its two storage tanks, increases the storage capacity of the rust remover, reduces the frequency of replenishment, and improves maintenance efficiency. The storage tanks are connected to the outlet pipe, providing the rust remover source for the outlet pipe. This connection allows the rust remover to flow smoothly from the storage tanks to the outlet pipe, and then through the nozzle or outlet to the steel pipe pile requiring maintenance.

[0008] As a further improvement to the above solution, several nozzles are provided, and the surfaces of several nozzles are fixedly connected to the inner walls of several liquid outlet pipes.

[0009] Through the above technical solution, several nozzle surfaces are fixedly connected to the inner walls of several outlet pipes. The function of the nozzles is to evenly spray the rust remover delivered from the outlet pipes onto the surface of the steel pipe pile. Even spraying ensures that all parts of the steel pipe pile surface can come into contact with the rust remover, improving the quality and efficiency of rust removal. This even spraying method can avoid situations where the rust remover is excessively concentrated or insufficient in certain areas, thus better protecting the steel pipe pile.

[0010] As a further improvement to the above solution, the bottom end of the X-shaped fixing block is fixedly connected to the top end of the base plate, two connecting plates are provided, the ends of the two connecting plates that are close to each other are fixedly connected to the surface of the X-shaped fixing block, a number of liquid outlets are provided, the number of liquid outlets are opened on the inner wall of the X-shaped fixing block, and the ends of the number of liquid outlet pipes that are close to each other are fixedly connected to the ends of the two connecting plates that are far apart from each other.

[0011] Through the above technical solution, the bottom end of the X-shaped fixing block is fixedly connected to the top end of the base plate, providing a stable support structure for the entire device. It can fix the position of the liquid outlet, ensuring that the liquid outlet can accurately deliver the rust remover to the vicinity of the steel pipe pile. With several liquid outlets inside, the rust remover can act on the steel pipe pile from multiple directions, improving the comprehensiveness of rust removal. The X-shaped fixing block, through its surface fixed connection to the connecting plate, organically combines all components together. It is a crucial connecting hub in the entire device structure, ensuring the integrity and stability of the device.

[0012] As a further improvement to the above solution, two U-shaped fixing blocks are provided, and the bottom ends of the two U-shaped fixing blocks are fixedly connected to the ends of the two connecting plates that are far apart from each other.

[0013] Through the above technical solution, the bottom ends of the two U-shaped fixing blocks are fixedly connected to the ends of the two connecting plates that are far apart from each other, and their inner walls are threadedly connected to the threaded rod. This provides a fixed installation position for the threaded rod, allowing it to move stably up and down within the block. Through the threaded connection, the U-shaped fixing blocks can precisely control the movement of the threaded rod, thereby adjusting the device's fixation and maintenance operations on the steel pipe pile.

[0014] As a further improvement to the above solution, two threaded rods are provided, and the surfaces of the two threaded rods are threadedly connected to the inner walls of the two U-shaped fixing blocks. Two connecting rods are provided, and the bottom ends of the two connecting rods are fixedly connected to the top ends of the two threaded rods.

[0015] Through the above technical solution, the surfaces of the two threaded rods are threadedly connected to the inner walls of the two U-shaped fixing blocks, with their top ends fixedly connected to the connecting rods and their bottom ends having limit blocks. By rotating the threaded rods, their height position within the U-shaped fixing blocks can be adjusted. When maintaining the steel pipe piles, the height of the threaded rods can be adjusted according to the actual conditions of the steel pipe piles, thereby enabling the device to be better fixed around the steel pipe piles and ensuring the smooth progress of maintenance work.

[0016] As a further improvement to the above solution, two rotating handles are provided, the surfaces of the two rotating handles are fixedly connected to the inner walls of the two connecting rods, and two limiting blocks are provided, the tops of the two limiting blocks are connected to the bottoms of the two threaded rods in a transmission connection.

[0017] Through the above technical solution, the top ends of the two limiting blocks are connected to the bottom ends of the two threaded rods. The main function of the limiting blocks is to prevent the threaded rods from coming out of the U-shaped fixing blocks, ensuring the integrity and stability of the device structure. During the operation of the device, especially when the threaded rods are moved up and down for adjustment, the limiting blocks can effectively restrict the movement range of the steel pipe piles, avoiding device failure due to the steel pipe piles coming out, thereby ensuring that maintenance work can be carried out continuously.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The main function of the liquid storage tank in this invention is to store rust remover. In deep foundation pit environments, PC steel pipe piles may be affected by corrosion, etc. The rust remover is used for rust removal and maintenance of the steel pipe piles. The presence of two liquid storage tanks increases the storage capacity of the rust remover, meeting the needs of rust removal for longer periods or larger areas of steel pipe piles. Each liquid storage tank is equipped with a suction pump, which stably delivers the rust remover to the outlet pipe. Throughout the operation of the maintenance device, the liquid storage tanks act as the source, continuously providing rust remover for subsequent rust removal work, ensuring the continuity of the rust removal process.

[0020] The device uses nozzles and outlets to apply rust remover from the storage tank to the PC steel pipe piles. The multiple nozzles and outlets ensure that the rust remover is sprayed more evenly onto the surface of the steel pipe piles, effectively removing rust, extending their service life, and ensuring the stability of the deep foundation pit structure.

[0021] This invention utilizes the interplay of an X-shaped fixing block, a connecting plate, a U-shaped fixing block, and a threaded rod within the device. The X-shaped fixing block and connecting plate serve to fix and connect the various components, ensuring the overall stability of the device. The combination of the U-shaped fixing block, threaded rod, connecting rod, rotating handle, and limiting block provides adjustability. For example, the position of the limiting block can be adjusted by rotating the threaded rod using the rotating handle, thus adapting to the maintenance work of PC steel pipe piles of different specifications or with different installation requirements.

[0022] Multiple outlet pipes, nozzles, and a rational structural layout allow for simultaneous treatment of multiple parts of the steel pipe pile during rust removal. This layout and design enable the rust removal and maintenance of the steel pipe pile to be completed in a shorter time, significantly improving work efficiency compared to some simple rust removal equipment or manual rust removal methods.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-5 This embodiment of a PC steel pipe pile maintenance device for deep foundation pits in soft soil includes a base plate 1, a liquid storage tank 2 at the top of the base plate 1, a liquid outlet pipe 3 at the top of the liquid storage tank 2, a nozzle 4 inside the liquid outlet pipe 3, an X-shaped fixing block 6 at the top of the base plate 1, a liquid outlet 5 on the inner wall of the X-shaped fixing block 6, a connecting plate 7 on the surface of the X-shaped fixing block 6, a U-shaped fixing block 8 on the surface of the connecting plate 7, a threaded rod 9 at the top of the U-shaped fixing block 8, a connecting rod 10 at the top of the threaded rod 9, a rotating handle 11 inside the connecting rod 10, and a limit block 12 at the bottom of the threaded rod 9.

[0033] The device is based on a base plate 1, on which key components such as a liquid storage tank 2, a liquid outlet pipe 3, a nozzle 4, and an X-shaped fixing block 6 are integrated, forming an efficient and flexible maintenance system. Two liquid storage tanks 2 are provided, with their bottom ends fixedly connected to the top of the base plate 1. Several liquid outlet pipes 3 are provided, with their bottom ends fixedly connected to the tops of the two liquid storage tanks 2. The two liquid storage tanks 2 are respectively fixed to the top of the base plate 1, and are used to store the chemical agents or clean water required for maintenance. The design of the liquid storage tanks 2 considers the balance between capacity and weight, ensuring that they meet the needs of deep pit operations without being excessively heavy.

[0034] Several nozzles 4 are provided, and the surfaces of these nozzles 4 are fixedly connected to the inner walls of several liquid outlet pipes 3. The liquid outlet pipes 3 extend from the top of the liquid storage tank 2, acting like blood vessels to transport liquid to each nozzle 4. The liquid outlet pipes 3 are made of corrosion-resistant and high-strength materials to adapt to the complex and ever-changing foundation pit environment. The nozzles 4 are evenly distributed inside the liquid outlet pipes 3. Through precise nozzle design, the liquid can be evenly sprayed onto the surface of the PC steel pipe pile in the form of a mist or a fine stream to achieve the purpose of cleaning, rust prevention, or reinforcement.

[0035] The bottom of the X-shaped fixing block 6 is fixedly connected to the top of the base plate 1, providing not only stable support but also cleverly utilizing the X-shaped structure to enhance the overall rigidity and stability. The liquid outlet 5 on the inner wall of the X-shaped fixing block 6 is connected to the liquid outlet pipe 3, ensuring accurate delivery of the liquid to the target area. Two connecting plates 7 are provided, with their ends close to each other fixedly connected to the surface of the X-shaped fixing block 6, serving not only as a connection but also as the installation base for the U-shaped fixing block 8. The design of the connecting plates 7 considers the need for easy disassembly and replacement, facilitating adjustments during maintenance. Several liquid outlets 5 are provided, located on the inner wall of the X-shaped fixing block 6, with their ends close to each other fixedly connected to the ends of the two connecting plates 7 that are far apart.

[0036] Two U-shaped fixing blocks 8 are provided. The bottom ends of the two U-shaped fixing blocks 8 are fixedly connected to the ends of the two connecting plates 7 that are far apart from each other. The design of the U-shaped structure not only ensures sufficient strength, but also facilitates the vertical installation and adjustment of the threaded rod 9.

[0037] There are two threaded rods 9, and the surfaces of the two threaded rods 9 are threadedly connected to the inner walls of the two U-shaped fixing blocks 8. There are two connecting rods 10, and the bottom ends of the two connecting rods 10 are fixedly connected to the top ends of the two threaded rods 9. This design allows users to adjust the height of the two threaded rods 9 simultaneously by rotating the handle 11, thereby achieving the clamping or loosening of the PC steel pipe pile.

[0038] Two rotary handles 11 are provided, and the surfaces of the two rotary handles 11 are fixedly connected to the inner walls of the two connecting rods 10. As the operating part of the adjustment system, the rotary handles 11 are designed with ergonomic principles in mind, making it easy for users to rotate and precisely control the height of the threaded rods 9. Two limit blocks 12 are provided, and the tops of the two limit blocks 12 are connected to the bottoms of the two threaded rods 9, which plays a safety protection role in preventing the threaded rods 9 from descending excessively or falling off.

[0039] The implementation principle of the PC steel pipe pile maintenance device for deep foundation pits in soft soil in this application embodiment is as follows: When the suction pump in the storage tank 2 is started, the rust remover in the storage tank 2 will be transported through the outlet pipe 3. Since the outlet pipe 3 is connected to the nozzle 4 and the outlet 5, the rust remover will flow to the nozzle 4 and the outlet 5 respectively. The rust remover sprayed from the nozzle 4 will be sprayed directly onto the outer surface of the PC steel pipe pile to chemically remove the rust on the surface. The rust remover flowing out of the outlet 5 will also act on the surface of the steel pipe pile, come into contact with the rust and react to remove the rust. In this process, the height of the limiting block 12 can be adjusted by adjusting the threaded rod 9, so that the whole device can better adapt to different steel pipe piles. For example, when maintaining a tall steel pipe pile, the limiting block 12 can be appropriately raised to ensure that the rust remover can be accurately sprayed onto the part that needs rust removal.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
