Description

Technical Field

[0001] The utility model relates to the technical field of foundation pipe piles, in particular to a pipe pile docking positioning device. Background Art

[0002] Prestressed pipe pile foundations are used for engineering foundations under poor geological conditions or when they need to withstand large loads. Prestressed pipe piles are usually made of high-strength concrete or steel, and have high compressive strength and flexural stiffness. One or more prestressed steel pipes are driven into the ground, and then the steel pipes are poured with concrete to form a prestressed structure that can withstand the load of the tension rod. When multiple prestressed steel pipes need to be driven in, at present, no device is used when connecting the upper section of the pipe pile with the lower section of the pipe pile during the construction process. The construction workers rely solely on their visual observation and experience, resulting in a large misalignment of the joints between the upper section of the pipe pile and the lower section of the pipe pile, affecting the overall quality of the pile body; the misalignment of the joints makes the overall structure of the pile body unstable, and it is easy to displace or deform when subjected to external loads or vibrations. In addition, the misalignment of the joints may also reduce the effective bearing area of ​​the pile body, thereby reducing its bearing capacity and failing to effectively disperse and transfer the load of the upper structure. Utility Model Content

[0003] In view of the problems existing in the above-mentioned prior art, the utility model provides a pipe pile docking and positioning device, which can effectively solve the problems existing in the above-mentioned prior art.

[0004] The technical solution of the utility model is:

[0005] According to one aspect of the utility model, it includes: a first arc-shaped plate, a second arc-shaped plate is hingedly provided at one end of the first arc-shaped plate, the first arc-shaped plate and the second arc-shaped plate can be opened and closed at the joint of the upper pipe pile and the lower pipe pile, the upper end surfaces of the first arc-shaped plate and the second arc-shaped plate are fixedly provided with a plurality of guide blocks, and the upper pipe pile slides into the joint of the lower pipe pile through the plurality of guide blocks.

[0006] Furthermore, a plurality of guide blocks are provided with a sloped surface at one end facing the pile body.

[0007] Furthermore, a plurality of the guide blocks are equidistantly distributed on the upper pipe pile and the lower pipe pile.

[0008] Furthermore, the other ends of the first arc-shaped plate and the second arc-shaped plate are fixedly connected by bolts.

[0009] Furthermore, a first extension plate is provided at the free end of the first arc plate extending toward the second arc plate; a second extension plate is provided at the free end of the second arc plate extending toward the first arc plate; when the device body is closed, the first extension plate fits with the second extension plate.

[0010] Furthermore, the first extension plate and the second extension plate are both provided with strip grooves, and the bolts are passed through the strip grooves.

[0011] Furthermore, the first arc plate and the second arc plate are both provided with annular convex strips extending inwards.

[0012] Furthermore, the upper and lower end surfaces of the annular convex strip are respectively in contact with the upper pipe pile and the lower pipe pile.

[0013] By adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0014] Firstly, through the guidance of the guide block, the upper pipe pile can dock with the lower pipe pile more accurately during the descent process. The outer wall of the upper pipe pile contacts the guide block and is guided and constrained by the guide block. The guide block enables the upper pipe pile to slide down along a predetermined trajectory and direction, avoiding the occurrence of offset and dislocation, greatly reducing the risk of dislocation, and the device body is easy to install, so construction personnel can easily complete the docking operation, reducing human errors and uncertainties in the docking process.

[0015] Secondly, the provision of the annular convex strip increases the contact area between the device body and the lower pipe pile, thereby increasing the friction force, so that the device body can be more firmly fixed on the upper end surface of the lower pipe pile. When the upper pipe pile moves toward the lower pipe pile, the upper pipe pile hits the guide block to prevent the device body from sliding or shifting during the docking process, thereby ensuring the accuracy and stability of the docking.

[0016] Thirdly, the strip groove allows the bolt to have a certain range of movement in the groove, which enables the device body to adapt to different pile body sizes during installation and fixation. Construction personnel can adjust the position of the bolt according to actual needs, making the fixation of the device body more flexible and precise, thereby improving construction efficiency.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is particularly noted that the following embodiments are only used to illustrate the present invention, but do not limit the scope of the present invention. Similarly, the following embodiments are only partial embodiments of the present invention rather than all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown, this solution provides a pipe pile docking and positioning device.

[0024] See also Figure 1 and Figure 3 , including: a first arc plate 11, a second arc plate 12 is hingedly provided at one end of the first arc plate 11, and the first arc plate 11 and the second arc plate 12 are openably and closably provided at the joint of the upper pipe pile B and the lower pipe pile A.

[0025] See also Figures 1 to 3 The upper end surfaces of the first curved plate 11 and the second curved plate 12 are fixed with a plurality of guide blocks 15, and the ends of the plurality of guide blocks 15 facing the pile body are provided with a slope surface 151; the upper pipe pile B slides into the joint of the lower pipe pile A through the plurality of guide blocks 15. The plurality of guide blocks 15 are evenly distributed on the upper pipe pile B and the lower pipe pile A, and specifically, the guide blocks 15 are distributed at the four equal parts of the upper end surfaces of the first curved plate 11 and the second curved plate 12; the guide blocks 15 are distributed at the four equal parts, which ensures the uniformity and stability of the lower pipe pile A and the upper pipe pile B when they are connected, and improves the construction quality of the overall pile body.

[0026] See also Figures 1 to 3, the other end of the first arc plate 11 and the second arc plate 12 are fixedly connected by bolts 16; the free end of the first arc plate 11 is extended toward the second arc plate 12 and provided with a first extension plate 111; the free end of the second arc plate 12 is extended toward the first arc plate 11 and provided with a second extension plate 121; when the device body 1 is closed, the first extension plate 111 and the second extension plate 121 fit together. Both the first extension plate 111 and the second extension plate 121 are provided with strip grooves 112, and the bolts 16 are passed through the strip grooves 112. The strip grooves 112 allow the bolts 16 to have a certain range of movement in the grooves, which enables the device body 1 to adapt to different pile body sizes during installation and fixing. The construction personnel can adjust the position of the bolts 16 according to actual needs, making the fixing of the device body 1 more flexible and accurate, thereby improving the construction efficiency.

[0027] See also Figures 1 to 3 , the first arc plate 11 and the second arc plate 12 are both provided with annular convex strips 14 extending inward. The upper and lower end surfaces of the annular convex strips 14 are respectively in contact with the upper pipe pile B and the lower pipe pile A. The provision of the annular convex strips 14 increases the contact area between the device body 1 and the lower pipe pile A, thereby increasing the friction force, so that the device body 1 can be more firmly fixed on the upper end surface of the lower pipe pile A. When the upper pipe pile B moves toward the lower pipe pile A, the upper pipe pile B hits the guide block 15, preventing the device body 1 from sliding or shifting during the docking process, thereby ensuring the accuracy and stability of the docking.

[0028] Working principle: the device body 1 is fixed to the upper end surface of the lower pipe pile A by bolts 16. When the lower end surface of the convex strip 14 abuts against the upper end surface of the lower pipe pile A, the bolts 16 are tightened. Then, the upper pipe pile B slowly descends under the action of the lifting equipment. During this process, the outer wall of the upper pipe pile B contacts the slope surface 151 of the guide block 15. Under the guidance and restraint of the guide block 15, the guide block 15 enables the upper pipe pile B to slide down along a predetermined track and direction, avoiding the occurrence of deviation and dislocation.

[0029] Of course, when multiple sections of pipe piles need to be driven in, a device body 1 is fixedly arranged between every two adjacent pipe piles.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
