[0024] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0025] As shown in Figs. 1-2 A pipe pile head cutting device, comprising a clamp plate 1, a hydraulic drive assembly, a positioning seat 3, a sleeve 4, a locking member, and an oil pump 10.

[0026] In this embodiment, the hydraulic drive assembly is movably arranged on one side of the clamp plate 1, and a clamping area for placing the pipe pile head is provided between the hydraulic drive assembly and the clamp plate 1. When the pipe pile head is placed in the clamping area, the hydraulic drive assembly and the clamp plate 1 can clamp the pipe pile head. The hydraulic drive assembly can be used to apply a pressing force to the pipe pile head in the clamping area, and the concrete on the surface of the pipe pile head can be crushed by the cooperation of the hydraulic drive assembly and the clamp plate 1, and the steel bars in the pile head can be prevented from being damaged. It can be applied to projects that require the pipe pile to withstand a large uplift force and require good anchoring with the upper structure, i.e. projects with high uplift force requirements. The hydraulic drive assembly as a whole can move towards or away from the side of the clamp plate 1, and the drive head 2 of the hydraulic drive assembly is movably arranged on one side of the clamp plate to adjust the width of the clamping area. The width of the clamping area can be adjusted by the displacement of the hydraulic drive assembly, and the stroke range of the hydraulic drive assembly can be adjusted, which is suitable for pipe piles of different diameters.

[0027] Among them, the projects with high uplift force requirements include bridge, high-rise building and other foundation engineering.

[0028] In this embodiment, the pipe pile head cutting device also has the beneficial effects of small structure, low noise, effective reduction of dust raising, and easy operation, and therefore can be applied to the following application scenarios:

[0029] Urban construction: when carrying out infrastructure construction in urban environment, due to the existence of surrounding residential areas or commercial areas, noise and dust control are very sensitive. The device is very suitable for such construction due to its characteristics of no noise and no dust.

[0030] Narrow space operation: For some sites that have been excavated but have limited space, large equipment cannot enter or is not convenient to use. In this case, this small and convenient device can be operated by a single person, and can flexibly cope with various complex terrains.

[0031] High uplift demand projects: In foundation engineering such as bridges and high-rise buildings, when pipe piles need to withstand large uplift forces and need to be well anchored with the upper structure, the use of this device can complete the removal of the pile head concrete without damaging the prestressed steel bars.

[0032] Mixed pile diameter worksite: There may be pipe piles of different diameters on a worksite, and this device can be adjusted to accommodate multiple pile diameters, so it has high practicality in such mixed worksites.

[0033] Emergency repair or reconstruction projects: For urgent repair tasks that require quick response or foundation reinforcement and reconstruction of existing buildings, the efficiency and ease of operation of this device make it a good solution.

[0034] To ensure that the steel bars are not damaged, the following key measures and techniques can be used:

[0035] Precise control of hydraulic pressure: By precisely adjusting the pressure provided by the hydraulic drive assembly, the force applied to the concrete can be moderate, effectively breaking the concrete without over-pressing the internal steel bars. This requires setting appropriate pressure parameters based on the specific pile structure and concrete strength.

[0036] Selective material breaking: The device uses a hydraulic drive assembly with clamps 1 to crush the concrete. This design can selectively act on the concrete, reducing the force acting directly on the steel bars. The design of the clamps 1 should consider matching the shape of the pile to maximize the contact area and distribute the applied pressure.

[0037] Step-by-step operation mode: During the breaking process, it is recommended to use a segmented and step-by-step approach, processing only a small portion of the concrete at a time. This avoids applying excessive force or force within a certain range, allowing for more precise control of the breaking process and protection of the steel bars.

[0038] Optimized equipment structure and size: Ensure that the overall design of the device is compact and flexible, allowing it to approach the pile without disturbing the steel bars. Additionally, by adjusting the position of the hydraulic drive assembly, the hydraulic drive assembly can be accurately positioned in the area of the concrete that needs to be broken, while avoiding the location of the steel bars.

[0039] Real-time monitoring and feedback mechanism: If possible, introduce sensors or other monitoring means during construction to monitor various parameters (such as pressure, displacement, etc.) in real time during the breaking process, so as to adjust the operation strategy in time to prevent accidental damage to the reinforcement.

[0040] In order to realize the position adjustment of the hydraulic drive assembly, the clamping plate 1 is fixed at one end of the positioning seat 3, and the hydraulic drive assembly is movably fixed at the other end of the positioning seat 3, that is, by adjusting the position of the hydraulic drive assembly on the positioning seat 3, the displacement of the hydraulic drive assembly in the direction away from or close to the clamping plate 1 is realized.

[0041] Specifically, in this embodiment, the hydraulic drive assembly includes a hydraulic cylinder and a sleeve 4, one of which is that the hydraulic cylinder is fixed on the end of the positioning seat 3 away from the clamping plate 1 through the sleeve 4, and one end of the hydraulic cylinder is movably fixed in the sleeve 4, that is, it can displace in the sleeve 4, thereby realizing its position adjustment, and the other is that the displacement of the sleeve 4 on the positioning seat 3 drives the displacement of the hydraulic cylinder, thereby realizing secondary position adjustment.

[0042] Among them, in order to realize the position locking of the hydraulic cylinder in the sleeve 4, a plurality of adjusting holes are arranged on the sleeve 4 along the length direction, the locking piece can be inserted into the adjusting hole, and can be connected with the hydraulic cylinder, when the hydraulic cylinder is connected with the locking piece, the locking piece can limit the continuous displacement of the hydraulic cylinder, thereby realizing the locking of its position.

[0043] Specifically, the locking piece is provided as a plug pin 5, which can be directly inserted into the adjusting hole and connected with the hydraulic drive assembly through the adjusting hole. In order to avoid the small swing of the hydraulic cylinder, the plug pin 5 is gap fitted with the adjusting hole, which can effectively avoid the front and back swing.

[0044] Among them, in order to realize the displacement of the sleeve 4 on the positioning seat 3, a positioning plate 6 is arranged on the end of the positioning seat 3 away from the clamping plate 1, the positioning plate 6 is provided with a threaded hole 7, and the outer side of the sleeve 4 is provided with an external thread. The sleeve 4 can be inserted into the threaded hole 7 and connected with the threaded hole 7 in threaded engagement, that is, by rotating the sleeve 4, the position adjustment of the sleeve 4 can be realized.

[0045] In order to avoid the sleeve 4 from separating from the positioning plate 6 due to misoperation, a limiting column 8 is arranged on the end of the sleeve 4 inside the positioning plate 6, which can abut with the inside of the positioning plate 6. This position is the farthest position of the sleeve 4 from the clamping plate 1, which can effectively prevent the sleeve 4 from separating from the positioning plate 6.

[0046] In this embodiment, in order to ensure the strength of the clamping plate 1, the clamping plate 1 can be provided as a steel plate, and in order to better clamp the pipe pile head, the steel plate can be provided as a U-shaped steel plate.

[0047] In order to facilitate holding, the handle 9 is further included, and at least two handles 9 are arranged on one side of the positioning seat 3 and the clamping plate 1 respectively, facilitating the gripping operation.

[0048] In the embodiment, the driving head 2 can be connected with the piston rod of the hydraulic cylinder, can be extended outside the sleeve 4, and can be abutted with the pile head, that is, the piston rod is extended to apply pressure on the pile head, and the oil pump 10 is communicated with the hydraulic cylinder through the oil pipe 11, and the hydraulic cylinder is provided with hydraulic oil through the oil pipe 11, so as to provide power for the movement of the piston rod.
