Description
Technical Field
[0001] This utility model relates to the field of construction, and in particular to a novel prestressed hollow support pile construction tool. Background Technology
[0002] Underground structural support is a crucial link in ensuring construction safety and subsequent use, and prestressed hollow support piles are favored due to their excellent mechanical properties and economic efficiency. However, many problems arise in actual construction. After a new support pile is driven, it is often difficult to fit tightly with the previous pile, causing deviations in the overall verticality of the support wall, significantly reducing the reinforcement effect, compromising the stability of the surrounding soil, and significantly increasing safety risks. Moreover, poor fit can also compromise the wall's waterproofing, leading to frequent groundwater leakage and other problems that seriously affect the normal progress of underground engineering. Utility Model Content
[0003] To improve the positioning accuracy of support pile construction, this application provides a novel prestressed hollow support pile construction tool.
[0004] This application provides a novel prestressed hollow support pile construction tool using the following technical solution: A novel prestressed hollow support pile construction tool includes: a base, on which two support seats are arranged opposite each other and vertically; a pressure roller, the two ends of the rotating shaft of the pressure roller are respectively rotatably connected to the support seats, the pressure roller is located at one edge of the base, and the pressure roller at least partially protrudes from the outer edge of the base.
[0005] By adopting the above technical solution, the two vertical support seats arranged opposite each other on the base provide a stable installation foundation for the pressure roller, which can be firmly set on one side edge of the base and partially protrude outside the edge of the base. In this way, during construction, the pressure roller can contact the support pile and play a positioning and limiting role for the support pile, so that the support pile can fit tightly with the previous pile, while ensuring that the support pile is driven in the correct vertical direction during the pile driving process, thus ensuring the accuracy of construction.
[0006] Optionally, it may also include a unidirectional component connected to the pressure roller, the unidirectional component restricting the pressure roller to rotate in only one direction.
[0007] By adopting the above technical solution, after the unidirectional component is connected to the pressure roller, it can restrict the pressure roller to rotate in only one direction. This can prevent the pressure roller from rotating in the opposite direction at will during the pile driving process, thereby controlling the positioning of the support pile and the direction of pile driving more accurately, preventing problems such as the position deviation of the support pile caused by the reverse rotation of the pressure roller, and further improving the construction quality.
[0008] Optionally, the one-way component includes a ratchet and a pawl. The ratchet is sleeved on the rotating shaft of the pressure roller and is fixedly connected to the rotating shaft of the pressure roller. The pawl is disposed on the base and engages with the ratchet.
[0009] By adopting the above technical solution, using ratchet and pawl as unidirectional components, the ratchet is sleeved on the rotating shaft of the pressure roller and fixedly connected to it, and the pawl is set on the base and cooperates with the ratchet. This structure is simple and reliable. Through the mechanical cooperation of the ratchet and pawl, the unidirectional rotation of the pressure roller can be stably and effectively restricted, ensuring that the pressure roller rotates in the predetermined direction during the piling process, thus assisting in the accurate construction of the support pile.
[0010] Optionally, the pawl is located on the side of the base away from the pressure roller, with one end of the pawl rotatably connected to the base and the other end extending above the ratchet and engaging with the ratchet.
[0011] By adopting the above technical solution, the pawl is located on the side of the base away from the pressure roller, which avoids spatial interference between the pawl and the pressure roller and support piles, ensuring that all components can work in an orderly and coordinated manner during construction. The pawl and the base are connected by a rotatable connection. When the pressure roller needs to be rotated in the opposite direction, such as during equipment debugging or to deal with some special construction situations, the operator can manually operate the pawl, using the rotatable connection point between it and the base as the axis, to easily remove the pawl from the teeth of the ratchet, releasing the restriction on the ratchet, thereby allowing the pressure roller to rotate in the opposite direction as needed.
[0012] Optionally, the base includes a first base plate and a second base plate, the first base plate and the second base plate are arranged in parallel, the pressure roller is arranged on the first base plate, and a hydraulic component is provided on the second base plate. The output end of the hydraulic component is connected to the first base plate, and the hydraulic component drives the first base plate to move closer to or away from the second base plate.
[0013] By adopting the above technical solution, the output end of the hydraulic component is used to drive the first base plate closer to or further away from the second base plate. After the second base plate is installed, the hydraulic component can be used to adjust the position of the first base plate relative to the second base plate as needed, thereby changing the position of the pressure roller from the previous pile, thus positioning the construction position of the support pile, ensuring that the pressure roller can cooperate with the support pile, and ensuring that the construction operation can be carried out smoothly and efficiently.
[0014] Optionally, the hydraulic assembly includes a hydraulic cylinder and a drive plate. The hydraulic cylinder is mounted on the second base plate, and the drive plate is mounted on the first base plate. The output end of the hydraulic cylinder is provided with a drive shaft that extends and retracts, and the drive shaft is connected to the drive plate.
[0015] By adopting the above technical solution, the hydraulic cylinder serves as the power source on the second base plate, and the output drive shaft extends and retracts to drive the drive plate on the first base plate, thereby realizing the horizontal movement of the first base plate. Using a hydraulic cylinder to control the movement of the first base plate offers the advantages of smooth and uniform power transmission, preventing sudden fluctuations. This allows for precise control of the first base plate's movement distance and final position, thereby accurately adjusting the horizontal position of the pressure roller. This results in more precise positioning of the support piles, effectively improving construction efficiency and ensuring construction quality.
[0016] Optionally, it also includes a guide component, the two ends of which are respectively connected to the first base plate and the second base plate, and the guide component restricts the first base plate to move only in the direction of approaching or moving away from the second base plate.
[0017] By adopting the above technical solution, the guide component connects to the first base plate and the second base plate at both ends, respectively, restricting the movement direction of the first base plate so that it can only move horizontally towards or away from the second base plate. When the hydraulic component drives the first base plate to move, without the constraint of the guide component, the first base plate may experience instability such as displacement, swaying, or deviation from the predetermined horizontal direction. These situations will affect the positioning accuracy of the pressure roller, thus adversely affecting the construction positioning of the support pile.
[0018] Optionally, the guide assembly includes a guide rod and a guide slot. The guide rod is disposed on the first base plate, and the guide slot is formed on the second base plate. One end of the guide rod passes through the guide slot, and the length direction of the guide rod is arranged along the output direction of the hydraulic assembly.
[0019] By adopting the above technical solution, the guide rod is fixed to the first base plate, with one end passing through a guide slot on the second base plate, and the length direction of the guide rod is set along the horizontal direction output by the hydraulic assembly. The guide rod and the guide slot cooperate, and when the hydraulic assembly drives the first base plate to move, the guide rod slides along the length direction of the guide slot, restricting the first base plate from moving towards or away from the second base plate in the horizontal direction. This reduces the possibility of the first base plate shifting relative to the second base plate, and avoids deviation in the direction of the force exerted by the pressure roller on the support pile due to the shift of the first base plate. This provides a continuous and stable positioning constraint for the support pile, directly improving the accuracy of the support pile position during construction.
[0020] In summary, this application includes at least one of the following beneficial effects: 1. The two vertically mounted support seats on the base provide the installation foundation for the pressure roller. The pressure roller contacts the support pile to play a positioning and limiting role. In addition, the one-way component restricts the unidirectional rotation of the pressure roller. The hydraulic component controls the horizontal position of the pressure roller, which can ensure that the support pile is driven along the correct vertical and horizontal direction during the pile driving process, so that it fits tightly with the previous pile, effectively reducing position deviation and improving the accuracy of construction.
[0021] 2. The pawl is located on the side of the base away from the pressure roller and is rotatably connected to the base. When the pressure roller needs to rotate in reverse during equipment debugging or special construction situations, the operator can manually operate the pawl to release the restriction on the ratchet, allowing the pressure roller to rotate in reverse as needed. At the same time, the hydraulic components can adjust the position of the first base plate relative to the second base plate as needed, thereby changing the relative position of the pressure roller and the support pile, allowing the equipment to flexibly adapt to different construction needs and scene changes, ensuring smooth construction operations.
[0022] 3. The hydraulic cylinder in the hydraulic assembly transmits power smoothly and evenly, and can accurately control the movement of the first base plate. The guide assembly restricts the first base plate to move only in a specific horizontal direction, avoiding instability such as deviation or swaying. It also prevents the force direction of the pressure roller on the support pile from deviating due to changes in the position of the components, and provides continuous and stable positioning constraints for the support pile. This makes the construction process more stable and orderly, ensures the overall verticality and structural stability of the support wall, and improves the overall project quality.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0029] This application discloses a novel prestressed hollow support pile construction tool, referring to... Figure 1 and 2 The system includes a base 1, which is composed of a first base plate 12 and a second base plate 13. The first base plate 12 and the second base plate 13 are arranged in parallel. Two support seats 11 are arranged opposite each other on the first base plate 12. A pressure roller 2 is provided between the two support seats 11. The two ends of the rotating shaft of the pressure roller 2 are rotatably connected to the two support seats 11 respectively. The pressure roller 2 is located at the edge of the first base plate 12 away from the second base plate 13, and the pressure roller 2 at least partially protrudes from the edge of the first base plate 12.
[0030] Reference Figure 1 and 2 The second base plate 13 is provided with a hydraulic assembly 4, which includes a hydraulic cylinder 41, a drive shaft 43 and a drive plate 42. The hydraulic cylinder 41 is located on the second base plate 13, and the output end of the hydraulic cylinder 41 is connected to the drive shaft 43. The drive shaft 43 is connected to the drive plate 42, and the drive plate 42 is located on the first base plate 12. The hydraulic cylinder 41 can drive the drive shaft 43 to extend and retract, and the drive shaft 43 pushes the drive plate 42 to move, so that the first base plate 12 can move closer to or further away from the second base plate 13.
[0031] In a preferred embodiment, refer to Figure 2 and 3 The system also includes a one-way component 3, which comprises a ratchet 31 and a pawl 32. The ratchet 31 is sleeved on the rotating shaft of the pressure roller 2 and fixedly connected to the rotating shaft of the pressure roller 2, and rotates together with the pressure roller 2. One end of the pawl 32 is disposed on the first base plate 12 and rotatably connected to the first base plate 12, and the other end extends above the ratchet 31 and engages with the ratchet teeth of the ratchet 31. Preferably, two sets of one-way components 3 are provided, and the two sets of one-way components 3 are respectively disposed at both ends of the rotating shaft of the pressure roller 2. Specifically, the side of the pressure roller 2 away from the second base plate 13 rotates downward.
[0032] Ratchet 31 is fitted onto and fixedly connected to the shaft of pressure roller 2, allowing it to rotate with pressure roller 2. Pad 32 is rotatably connected at one end to the first base plate 12, and engages with the ratchet teeth of ratchet 31 at the other end. Two sets of pawls are provided, corresponding to both ends of the shaft of pressure roller 2, forming a stable unidirectional rotation restriction. During the driving of the support piles, when pressure roller 2 rotates forward, pawl 32 smoothly passes over the ratchet teeth of ratchet 31, without affecting normal construction operations, allowing pressure roller 2 to assist in the vertical positioning of the support piles. If pressure roller 2 tends to rotate in the opposite direction, pawl 32 engages with the ratchet teeth of ratchet 31. Through the cooperation of the mechanical structure, it strongly prevents pressure roller 2 from rotating in the opposite direction, avoiding positional deviations of the support piles caused by reverse rotation and ensuring that the support piles are always driven into the foundation in the correct direction.
[0033] In a preferred embodiment, refer to Figure 2 It also includes a guide assembly 5, which includes a guide rod 51 and a guide slot 501. The guide slot 501 is formed on the second base plate 13. The length direction of the guide rod 51 is set along the output direction of the hydraulic assembly 4. One end of the guide rod 51 is connected to the first base plate 12, and the other end extends into the guide slot 501. The inner wall of the guide slot 501 abuts against the outer periphery of the guide rod 51. Specifically, the guide assembly 5 is provided in two parts, with the two guide assemblies 5 respectively located on both sides of the first base plate 12. When the hydraulic assembly 4 drives the first base plate 12 to move horizontally, the guide rod 51 slides synchronously along the guide slot 501. The inner wall of the slot limits the circumferential movement of the guide rod 51, restricting the movement trajectory of the first base plate 12 and preventing it from being unstable, such as lateral deviation, angular tilt, or swaying. This ensures that the first base plate 12 moves smoothly only in the horizontal direction close to or away from the second base plate 13, effectively preventing the force direction of the pressure roller 2 on the support pile from deviating from the preset horizontal direction due to the deviation of the first base plate 12. This ensures that the pressure roller 2 is tightly fitted with the support pile and the pressure is uniform, improving the positioning accuracy of the support pile during pile driving and ensuring that each pile 100 of the support wall is tightly fitted and vertical as a whole.
[0034] The implementation principle of a novel prestressed hollow support pile construction tool in this application embodiment is as follows: (Refer to...) Figure 4The pressure roller 2 is positioned directly opposite the pile body 100. The new prestressed hollow support pile construction tool is set at a distance of one pile body 100 width from the previous pile. The second base plate 13 is fixed and positioned with screws. The hydraulic cylinder 41 is adjusted to control the drive shaft 43 to drive the drive plate 42 to move, so that the first base plate 12 moves closer to or further away from the second base plate 13. After the distance between the pressure roller 2 and the previous pile is equal to the width of the pile body 100, the first base plate 12 is fixed and positioned with screws. At this time, the space between the pressure roller 2 and the previous pile is the pile driving positioning space for the pile body 100. The pile body 100 is driven into the foundation by the pile driver. Under the limiting and squeezing of the pressure roller 2, the pile body 100 is closely attached to the previous pile, reducing the possibility of the pile body 100 deviating during the pile driving process. The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
