Description

Technical Field

[0001] The present application relates to the technical field of building foundation engineering, and in particular to a construction device and a construction method of a concrete pipe pile. Background Art

[0002] Concrete pipe piles, as a common foundation engineering component, are widely used in various construction projects. With the development of the times, the scale of construction projects has continued to expand, and the requirements for foundation bearing capacity have also continued to increase. This has driven the continuous advancement and innovation of concrete pipe pile technology. The development of concrete pipe pile technology has played a significant role in ensuring building stability and improving building safety, providing a solid foundation for the construction of large and high-rise buildings. However, in the face of new demands and challenges, traditional technologies have gradually exposed some limitations.

[0003] Common concrete pipe pile construction methods include hammering, static pressure, and vibration pile driving. The hammering method uses a heavy hammer to drive the pipe pile into the soil, which is fast but noisy and prone to damage. The static pressure method uses hydraulic equipment to slowly press the pipe pile in, which offers high precision but requires strict geological conditions. The vibration pile driving method uses high-frequency vibration to reduce soil resistance and is suitable for loose formations, but it consumes more energy. During pipe pile construction, it is recommended to use

[0004] With respect to the above-mentioned related technologies, the existing concrete pipe pile construction technology has obvious defects. Traditional construction methods are gradually unable to meet the requirements in terms of efficiency, precision and stability, and the construction period is long. Regardless of the method used for piling, the pile body is sent into the foundation by the piling equipment. When the next section of the pile body is hoisted, manual intervention and operation are often required to adjust the position of the pile body to be installed so that the two adjacent pile bodies are aligned. The manual operation method is inefficient. In addition, the existing equipment does not provide sufficient protection for pile bodies of different heights, which can easily cause the pile body to shake, affecting the construction quality and progress.

[0037] Reference Figure 3 When it is necessary to clamp another pile body, the two first fixing members 22 need to slide in the second direction toward the side away from each other, so that the other pile body to be installed can be lifted between the two first fixing members 22 by the lifting equipment. In order to enable the two second fixing members 23 to remain stationary when the first fixing member 22 slides in the second direction, so as to locate the position of the pile body to be installed, a first cylinder 56 is provided between the first mounting block 55 and the first fixing member 22, and the cylinder shell of the first cylinder 56 is fixedly connected to the first mounting block 55. The piston rod of the first cylinder 56 is parallel to the first direction and fixedly connected to the first fixing member 22. When it is necessary to clamp another pile body, the first cylinder 56 drives the two first fixing members 22 to slide in the direction away from each other, and the lifting equipment lifts the pile body between the two first fixing members 22.

The sliding of the second cylinder 7 along the first direction drives the second fixing member 23 to slide along the first direction, so that the second fixing member 23 can protectively clamp piles of different heights, and the second fixing member 23 slides along the first direction, so that the positioning rod 41 can be inserted into the first accommodating groove 222, and the positioning rod 41 positions the first fixing member 22.

[0039] Reference Figure 4, since there may be a slight error in the diameters of the two adjacent pile sections, when the positioning rod 41 deviates from the first positioning slot, in order not to affect the sliding of the second fixing member 23, the positioning rod 41 is slidably connected to the second fixing member 23 along the first direction. Specifically, the positioning assembly 4 also includes an elastic member 42. The second fixing member 23 is close to the first fixing member 22 and a second accommodating slot 233 is opened along the first direction. The expansion and contraction direction of the elastic member 42 is parallel to the first direction. One end of the elastic member 42 is fixedly connected to the bottom wall of the second accommodating slot 233, and the other end is fixedly connected to the positioning rod 41. The elastic member 42 has a force that drives the positioning rod 41 to slide toward the side away from the second accommodating slot 233 under the recoverable deformation.

Under the action of the elastic member 42, one side of the positioning rod 41 contacts the bottom wall of the first fixing frame, and the positioning rod 41 is further gradually pressed into the second accommodating groove 233, thereby not affecting the protection of the pile body by the second fixing member 23. In this embodiment, the elastic member 42 is a compression spring.

[0040] Reference Figure 4 In order to further improve the protection performance of the pile body, the first accommodating groove 222 is connected with the first clamping area 221 along the second direction, and the second accommodating groove 233 is connected with the second clamping area 231 along the second direction. One side of the positioning rod 41 contacts the side wall of the pile body, and the positioning rod 41 can further protect the pile body.

[0041] Reference Figure 4 In order to further improve the protective performance of the positioning rod 41 on the pile body, the positioning rod 41 is parallel to the first direction, and a third arc groove 411 is opened along the first direction on the side of the positioning rod 41 close to the second clamping area 231. The third arc groove 411 is smoothly connected to the second arc groove 232, and the third arc groove 411 is smoothly connected to the first arc groove 223, thereby increasing the contact area between the positioning rod 41 and the pile body.
