Description

Technical Field

[0001] This utility model relates to the field of silt removal technology for pipe piles, specifically a silt removal device for static pressure pipe pile holes. Background Technology

[0002] Static pressure piling is a method of engineering pile foundation construction. Static pressure piling involves using a static pile driver's mechanism, with the machine's own weight and counterweights on the frame providing the reaction force, to drive precast piles into the soil. Advantages of static pressure piling include completely avoiding the vibration, noise, and pollution generated by hammer piling, thus offering advantages such as no damage to the pile, no noise, no vibration, no impact, and no pollution during construction.

[0003] During the construction of static pressure pipe piles, soil falls into the pipe pile due to the movement of the pile driver. With the help of rainwater, it accumulates into silt over a long period of time.

[0004] Existing silt removal devices for static pressure pipe pile holes are often unable to be used with pile holes of different inner diameters and different depths; therefore, they do not meet the current requirements. In response, we propose a silt removal device for static pressure pipe pile holes. Utility Model Content

[0005] The purpose of this utility model is to provide a silt removal device for static pressure pipe pile holes, so as to solve the problems mentioned in the background art, which are often unable to be used for pile holes with different inner diameters and are difficult to be used for pile holes with different depths.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a silt removal device for static pressure pipe pile holes, comprising connecting rods, a silt removal rod movably mounted at the bottom end of the lowest connecting rod, a plurality of fixed scraping plates fixedly mounted in a spiral shape on the outer surface of the bottom end of the silt removal rod, movable scraping plates movably mounted on the outer surface of each fixed scraping plate, a connector fixedly mounted at the top end of each connecting rod, a insertion groove provided on the top surface of each connector, and an assembly groove provided at the top end of each silt removal rod, the bottom end of the lowest connecting rod movably engaging into the assembly groove, and the bottom ends of the remaining connecting rods movably engaging into the insertion groove.

[0007] Preferably, the outer surface of the fixed scraping plate is provided with a spring groove, and a compression spring is movably installed between the movable scraping plate and the inside of the spring groove. The bottom surface of the outer side of the movable scraping plate is provided with a slope.

[0008] Preferably, each of the connecting rods has two connecting rod side grooves at the bottom of its outer surface. Each connecting rod side groove has a limiting block slidably installed inside it. A compression spring is movably installed between the limiting block and the inside of the connecting rod side groove. The inner wall surfaces of the insertion groove and the assembly groove each have two limiting grooves, and the limiting blocks are slidably inserted into the limiting grooves.

[0009] Preferably, two pressing rods are movably mounted on the outer surface of the connector and two pressing rods are movably mounted on the outer surface of the sludge removal rod. Pushing grooves are provided inside the connector and the sludge removal rod near the pressing rods. The pressing rods are slidably inserted into the pushing grooves. Limiting plates are fixedly mounted on the outer surface of the pressing rods. Pushing springs are movably mounted between the limiting plates and the inside of the pushing grooves. The inner surface of the pressing rods is in contact with the surface of the limiting blocks.

[0010] Preferably, a handle is fixedly installed on the outer surface of the connecting rod at a position below the connector.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the cooperation of a fixed scraper plate and a movable scraper plate, allows the device to be used in a way that the movable scraper plate is pushed outward from the surface of the fixed scraper plate by the elasticity of the compression spring. This allows the device to be adapted to pipe piles of different inner diameters for sludge removal. When removing sludge, the fixed scraper plate and the movable scraper plate arranged in a spiral shape scrape the inner wall of the pipe pile. The spiral structure cuts the sludge and moves it to the position above the fixed scraper plate. When the device is pulled upward, all the sludge will be pulled out.

[0013] 2. This utility model, through the cooperation of connecting rods and insertion slots, allows the device to be used by inserting connecting rods into the insertion slots, thereby combining and installing multiple connecting rods together, thus extending the length of the device and making it adaptable to pipe piles of different depths for silt removal operations.

[0014] 3. This utility model, through the cooperation of the pressing rod and the limiting block, allows the device to fix the connecting rod in place when the connecting rod is inserted into the insertion slot or assembly slot. The limiting block on the outer surface of the connecting rod will be inserted into the limiting slot due to the elastic potential energy of the compression spring. This also allows each connecting rod to rotate simultaneously when the upper connecting rod is rotated. When the connecting rod needs to be removed, the two pressing rods can be pressed inwards. The pressing rods will then push the limiting block back into the side slot of the connecting rod, allowing the connecting rod to be pulled upwards and removed. This facilitates the storage or maintenance of the connecting rod. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 This utility model provides an embodiment of a silt removal device for static pressure pipe pile holes, comprising a connecting rod 1, a silt removal rod 6 movably installed at the bottom end of the lowest connecting rod 1, a plurality of fixed scraping plates 7 being spirally fixedly installed on the outer surface of the silt removal rod 6 near the bottom end, movable scraping plates 8 being movably installed on the outer surface of each fixed scraping plate 7, a connector 2 being fixedly installed at the top end of each connecting rod 1, and a insertion groove 3 being provided on the top surface of each connector 2, and an assembly groove 9 being provided at the top end of the silt removal rod 6, the bottom end of the lowest connecting rod 1 being movably inserted into the assembly groove 9, and the bottom ends of the remaining connecting rods 1 being movably inserted into the insertion groove 3.

[0023] By combining the fixed scraper 7 and the movable scraper 8, the device can be adapted to remove sludge from pipe piles of different inner diameters by using the elasticity of the compression spring 11 to push the movable scraper 8 outward from the surface of the fixed scraper 7. When removing sludge, the spirally arranged fixed scraper 7 and movable scraper 8 scrape the inner wall of the pipe pile, and the spiral structure cuts the sludge and moves it to the position above the fixed scraper 7. When the device is pulled upward, all the sludge will be pulled out.

[0024] The outer surface of the fixed scraper 7 is provided with spring grooves 10, and a compression spring 11 is movably installed between the movable scraper 8 and the inside of the spring grooves 10. The bottom surface of the outer side of the movable scraper 8 is provided with a bevel.

[0025] Two connecting rod side grooves 15 are provided on the outer surface of the connecting rod 1 near the bottom. Limiting blocks 17 are slidably installed inside the connecting rod side grooves 15. Compression springs 16 are movably installed between the limiting blocks 17 and the inside of the connecting rod side grooves 15. Two limiting grooves 18 are provided on the inner wall surfaces of the insertion groove 3 and the assembly groove 9. The limiting blocks 17 are slidably inserted into the inside of the limiting grooves 18.

[0026] Two pressing rods 5 are movably installed on the outer surface of the connector 2 and two pressing rods 5 are movably installed on the outer surface of the sludge removal rod 6. Pushing grooves 12 are provided inside the connector 2 and the sludge removal rod 6 near the pressing rods 5. The pressing rods 5 are slidably inserted into the pushing grooves 12. Limiting plates 13 are fixedly installed on the outer surface of the pressing rods 5. Pushing springs 14 are movably installed between the limiting plates 13 and the inside of the pushing grooves 12. The inner surface of the pressing rods 5 is in contact with the surface of the limiting block 17.

[0027] By combining the connecting rod 1 and the insertion slot 3, multiple connecting rods 1 can be combined and installed by inserting the connecting rod 1 into the insertion slot 3 during use, thereby extending the length of the device and making it suitable for silt removal operations on pipe piles of different depths.

[0028] Handles 4 are fixedly installed on the outer surface of the connecting rod 1 at a position below the connector 2.

[0029] By cooperating with the pressing rod 5 and the limiting block 17, when the connecting rod 1 is inserted into the insertion slot 3 or the assembly slot 9, the limiting block 17 on the outer surface of the connecting rod 1 will be inserted into the limiting slot 18 due to the elastic potential energy of the compression spring 16, thereby fixing the connecting rod 1. When rotating the upper connecting rod 1, each connecting rod 1 can rotate simultaneously. When it is necessary to remove the connecting rod 1, the two pressing rods 5 can be pressed inward. At this time, the pressing rods 5 will push the limiting block 17 back into the connecting rod side slot 15. Then the connecting rod 1 can be pulled upward to remove it, which is convenient for the storage or maintenance of the connecting rod 1.

[0030] In use, the silt removal device for static pressure pipe pile holes first assembles multiple connecting rods 1 according to the depth of the pipe pile, and installs the lowest connecting rod 1 inside the silt removal rod 6. Then, the device is placed inside the pipe pile. At this time, the inclined surface of the outer surface of the movable scraper 8 will touch the surface of the pipe pile, thus retracting into the spring groove 10. When the fixed scraper 7 enters the pipe pile, the movable scraper 8 will be ejected from the spring groove 10 by the elastic potential energy of the compressed spring 11 and will fit against the inner wall of the pipe pile. Then, the silt on the inner wall of the pipe pile is scraped off by the movable scraper 8, making the device adaptable to different depths. When performing sludge removal operations on pipe piles with the same inner diameter, the spirally arranged fixed scraper 7 and movable scraper 8 scrape the inner wall of the pipe pile. The spiral structure cuts the sludge and moves it above the fixed scraper 7. Pulling the device upwards pulls out all the sludge. After the connecting rod 1 is inserted into the insertion slot 3 or assembly slot 9, the limiting block 17 on the outer surface of the connecting rod 1 inserts into the limiting groove 18 due to the elastic potential energy of the compression spring 16, thus fixing the connecting rod 1. This allows each connecting rod 1 to rotate simultaneously when the upper connecting rod 1 is rotated.

[0031] When it is necessary to remove the connecting rod 1, the two pressing rods 5 can be pressed inward. At this time, the pressing rods 5 will push the limiting block 17 to retract into the side groove 15 of the connecting rod. Then the connecting rod 1 can be pulled upward to remove it, which makes it convenient to store or maintain the connecting rod 1.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
