Description

Technical Field

[0001] This invention belongs to the field of highway construction technology, specifically relating to a waste soil cleaning device at the bottom of precast pipe piles. Background Technology

[0002] Precast pipe piles play a crucial role in highway construction. They can penetrate deep into the ground, significantly improving the bearing capacity of the foundation through their large cross-section and depth. Because they can penetrate soft soil layers to reach harder ones, they reduce road damage caused by uneven foundation settlement. Their corrosion resistance and anti-aging properties provide long-term stability and reduce maintenance costs. However, soil, especially highly cohesive soil, may adhere to the inside of the pipe pile, affecting the uniformity and setting process of the concrete, leading to a decrease in concrete strength. The presence of soil may also form an isolation layer between the pipe pile and the concrete, reducing their bond strength and thus lowering the overall structural bearing capacity. Moisture and corrosive substances in the soil may penetrate into the concrete, reducing its durability over time. Therefore, a cleaning device is needed to efficiently clean the inside of the precast pipe piles. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a waste soil cleaning device for the bottom of precast pipe piles, which can efficiently clean the inside of the precast pipe piles.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The present invention includes a high-pressure water pump, the output end of which is connected to a thick water pipe, and the end of which is connected to a cylinder seat. Three sliding feet are fixed on the outside of the cylinder seat, and the sliding feet are equipped with rollers. The rollers roll along the extension direction of the precast pipe pile. Supported by the three sliding feet, the cylinder seat moves along the inner axis of the precast pipe pile. The end of the cylinder seat is also rotatably connected to a nozzle, and the nozzle is equipped with a plurality of nozzles. The spray direction of the nozzles is tangent to the coaxial circle of the cylinder seat, so that the nozzle rotates when spraying water.

[0006] Furthermore, the sliding foot includes a base cylinder and an extension cylinder. The extension cylinder is coaxially threaded to the end of the base cylinder. A connecting seat is rotatably connected to the end of the extension cylinder. A wheel seat is slidably provided on the connecting seat. A spring is supported between the wheel seat and the connecting seat. A connecting column is fixed on the wheel seat. A roller is rotatably provided at each end of the connecting column.

[0007] Furthermore, the outer side of the end of the extension tube is provided with a hexagonal head for easy clamping and rotation.

[0008] Furthermore, it also includes a scrubbing section, which includes two arc-shaped strips, which are respectively hinged to the front and rear ends of the nozzle. The bending direction of the arc-shaped strips is biased towards the rotation direction of the nozzle. A plurality of brush strips are provided between the arc-shaped strips, and a plurality of rubber brush teeth are arranged on the brush strips. The plurality of brush strips are arranged along the extension direction of the arc-shaped strips.

[0009] Furthermore, it also includes an adjustment unit, which includes a flange seat fixed to the top of the precast pipe pile. A take-up roller is rotatably mounted on the flange seat, and a thin iron wire is wound on the take-up roller. A guide ring is provided at the end of the coarse water pipe near the cylinder seat. A sleeve is slidably mounted coaxially at the end of the cylinder seat near the nozzle. A retaining ring is provided at the lower end of the sleeve. A retaining ring is provided on the outer side of the end of the nozzle near the cylinder seat. The retaining ring and the retaining ring have retaining teeth on their opposite sides. A spring is provided between the retaining ring and the cylinder seat. The thin iron wire extends from the take-up roller, passes through the guide ring, and connects to the sleeve.

[0010] The beneficial effects of this invention are as follows:

[0011] This invention is used for rapid cleaning of the inner side of precast pipe piles inserted into the ground during highway construction. A thick water pipe, designed to prevent excessive self-torsion, serves as the hydraulic output and traction mechanism, extending a cylindrical support into the precast pipe pile. Three sliding feet and rollers on the inner side of the support allow the support to move up and down along the inner side of the precast pipe pile. The rollers, moving along the extension direction of the precast pipe pile, exert friction on its side, thus enabling movement along the pile while preventing tangential rotation of the rollers on the pile's side. The cleaning is achieved through the support of the sliding feet and rollers, and the use of a thick water pipe... The traction of the pipe causes the cylinder seat to move up and down along the precast pipe pile without rotating. The nozzle, which is rotatably sealed to the cylinder seat, is connected to the water pipe. Water is ejected from the nozzle on the nozzle. The nozzle is tangent to the coaxial circle of the cylinder seat, so that when the nozzle ejects water, the nozzle rotates under the impact force. In conjunction with the movement of the cylinder seat, it impacts and cleans the inner bottom of the precast pipe pile, ensuring that the inner side of the precast pipe pile is thoroughly cleaned. This prevents the soil on the inner side of the precast pipe pile from affecting the adhesion of the concrete during concrete pouring, thus improving the integrity of the precast pipe pile. This device is simple to operate and has high cleaning efficiency.

[0023] like Figures 1-8 As shown, this invention discloses a waste soil cleaning device for the bottom of precast pipe piles, used for cleaning the inner bottom of precast pipe piles embedded in the ground during highway construction. Figure 1 It includes a high-pressure water pump 1 that outputs water, and the output end of the high-pressure water pump 1 is connected to a thick water pipe 2. The outer diameter of the thick water pipe 2 is set at 4-6cm, and it has good resistance to torsion and friction. Figure 2 As shown, the end of the thick water pipe 2 is connected to an iron cylinder seat 3. Three sliding feet 4 are fixedly arranged in an array on the outer side of the cylinder seat 3. Each sliding foot 4 is equipped with a roller 8, which rolls along the extension direction of the precast pipe pile. Supported by the three sliding feet 4, the cylinder seat 3 moves along the inner axis of the precast pipe pile. A nozzle 5 is also rotatably connected to the end of the cylinder seat 3. The nozzle 5 is coaxially arranged with the cylinder seat 3 and rotatably sealed. Figure 4As shown, the nozzle 5 is provided with a plurality of nozzles 51, and the spraying direction of the nozzles 51 is tangent to the coaxial circle of the cylinder base 3, so that the nozzle 5 rotates when spraying water.

[0024] This device is used for rapid cleaning of the inside of precast pipe piles inserted into the ground during highway construction. A thick water pipe 2, which prevents excessive twisting, serves as the hydraulic output and traction mechanism to extend a cylindrical base 3 into the precast pipe pile. Three sliding feet 4 on the inside of the cylindrical base 3, along with rollers 8 mounted on the sliding feet 4, allow the cylindrical base 3 to move up and down along the inside of the precast pipe pile. The rollers 8, moving along the extension direction of the precast pipe pile, exert friction on the side of the pile, thus enabling movement along the pile while preventing tangential rotation of the rollers 8 on the side of the pile. Supported by the sliding feet 4 and rollers 8, and the thick water pipe... The traction of component 2 causes the cylinder seat 3 to move up and down along the precast pipe pile without rotating. The nozzle 5, which is rotatably sealed to the cylinder seat 3, is connected to the water pipe. Water flows out from the nozzle 51 on the nozzle 5. The nozzle 51 is tangent to the coaxial circle of the cylinder seat 3, so that when the nozzle 51 ejects water, the nozzle 5 rotates under the impact force. In conjunction with the movement of the cylinder seat 3, the inner bottom of the precast pipe pile is impacted and cleaned, ensuring that the inner side of the precast pipe pile is thoroughly cleaned. This prevents the soil on the inner side of the precast pipe pile from affecting the bonding ability of the concrete during concrete pouring, and improves the integrity of the precast pipe pile. This device is simple to operate and has high cleaning efficiency.

[0025] In further proposals, such as Figure 5 and Figure 6 As shown, the sliding foot 4 includes a base cylinder 41 and an extension cylinder 42. The extension cylinder 42 is coaxially threaded to the end of the base cylinder 41. A connecting seat 43 is rotatably connected to the end of the extension cylinder 42. A wheel seat 44 is slidably provided on the connecting seat 43. A spring is supported between the wheel seat 44 and the connecting seat 43. A connecting column 45 is fixed on the wheel seat 44. A roller 8 is rotatably provided at both ends of the connecting column 45.

[0026] In this design, the threaded connection between the extension cylinder 42 and the bottom cylinder 41 allows the length of the entire sliding foot 4 to be adjusted, enabling the device to adapt to precast pipe piles of different inner diameters. A spring is installed between the wheel seat 44 and the connecting seat 43, allowing for elastic displacement and clearance between them. When the nozzle 5 moves along the precast pipe pile, the roller 8 can pass over the inner uneven surface of the precast pipe pile, preventing jamming. By installing two vertical rollers 8 on each sliding foot 4, the axial movement stability of the entire device inside the precast pipe pile is improved. Compared to a single-wheel structure, the nozzle 5 of this structure always remains in the same direction as the axis of the precast pipe pile, ensuring the balance of the water flow impact force of the nozzle 5 and preventing the structure from being misaligned and jammed in the precast pipe pile. Preferably, the outer side of the end of the extension cylinder 42 is provided with a hexagonal head 46 for easy clamping and rotation, so as to quickly adjust the length of each sliding foot 4.

[0027] In further proposals, such as Figure 2 As shown, it also includes a scrubbing section 6, which includes two arc-shaped strips 61. The two arc-shaped strips 61 are respectively hinged to the front and rear ends of the nozzle 5. The bending direction of the arc-shaped strips 61 is biased towards the rotation direction of the nozzle 5. A plurality of brush strips 62 are provided between the arc-shaped strips 61. A plurality of rubber brush teeth 63 are arranged on the brush strips 62. The plurality of brush strips 62 are arranged along the extension direction of the arc-shaped strips 61.

[0028] Through this structure, the centrifugal force generated during the rotation of the nozzle 5 causes the arc-shaped strip 61 to open, and the multiple brush strips 62 on the arc-shaped strip 61 come into contact with the inner side of the precast pipe pile. The rubber brush teeth 63 brush the inner side of the precast pipe pile, removing the soil from the inner side of the precast pipe pile. This structure can be adapted to precast pipe piles with different inner diameters, as well as precast pipe piles with uneven inner diameters.

[0029] In further proposals, such as Figure 3 , Figure 5 and Figure 7 As shown, it also includes an adjustment unit 7, which includes a flange seat 71 fixed to the top of the precast pipe pile. The flange seat 71 can be temporarily fixed to the end surface of the precast pipe pile by screws. A winding roller 72 is rotatably mounted on the flange seat 71, and a thin iron wire 73 is wound on the winding roller 72. A guide ring 21 is provided at the end of the coarse water pipe 2 near the cylinder seat 3. A sleeve 31 is coaxially slidably mounted at the end of the cylinder seat 3 near the nozzle 5. Figure 8 As shown, the lower end of the sleeve 31 is provided with a retaining ring 32, and the outer side of the nozzle 5 near the cylinder base 3 is provided with a retaining ring 52. The opposing surfaces of the retaining ring 32 and the retaining ring 52 are respectively provided with retaining teeth. (Refer to...) Figure 8 The retaining ring 52 is also provided with the same tooth structure as the retaining ring 32. A spring is provided between the retaining ring 32 and the cylinder seat 3. The thin iron wire 73 extends from the winding roller 72, passes through the guide ring 21, and is connected to the sleeve 31.

[0030] By setting this structure, when the nozzle 5 moves vertically, the thin iron wire 73 and the thick water pipe 2 extend synchronously. By tightening and loosening the take-up roller 72, the sleeve 31 pulled by the thin iron wire 73 moves along the cylinder seat 3. When the thin iron wire 73 is loosened, the retaining ring 32 and the retaining ring 52 move away from each other under the action of the spring. The cylinder seat 3 and the nozzle 5 are connected by a rotating seal. At this time, the nozzle 5 rotates under the action of the water flow to clean the inside of the precast pipe pile. When encountering a section that needs to be cleaned in particular, the retaining ring 32 and the retaining ring 52 are locked by tightening the thin iron wire 73. At this time, the cylinder seat 3 and the nozzle 5 are fixedly connected. The water flow no longer drives the nozzle 5 to rotate. The water jet energy is no longer consumed by the rotation of the nozzle 5. The water jet force increases and the spray position is fixed, so that stubborn surfaces can be cleaned.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
