However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems and devices are omitted to avoid unnecessary details that hinder the description of the present invention.

[0029] The following is combined with Figure 1-2 The preferred technical scheme of the utility model is further illustrated with embodiments.

[0031] The utility model does not limit the number of the second traction chains 4, and those skilled in the art can set it according to actual conditions. In practical applications, multiple second traction chains 4 are evenly connected to the crossbeam 3 at a preset distance, and the length and other dimensions of the crossbeam 3 are determined according to the number of the second traction chains 4 and the diameter and weight of the pipe pile. The distance between the connection points of two adjacent second traction chains 4 on the crossbeam 3 matches the diameter of the pipe pile to be towed. The pipe pile in the specific embodiment is specifically a PHC pile 8.

[0032] In this embodiment, a plurality of branch chains 7 are provided at one end of each second traction chain 4 away from the cross beam 3 ; one end of each branch chain 7 is connected to the second traction chain 4 , and the other end is connected to the connecting end of the pipe pile.

[0033] Among them, the other ends of the multiple branch chains 7 are evenly connected to the connecting ends of the pipe piles. The number of branch chains 7 can be two, three or four, etc. The connecting ends of the pipe piles are evenly provided with bolt holes matching the number of branch chains 7, and the ends of the multiple branch chains 7 away from the second traction chain 4 are connected to the corresponding bolt holes.

[0034] like Figure 1 As shown, on the basis of ensuring a stable connection with the pipe pile, in order to optimize the structure, there are two branch chains 7; the two branch chains 7 are respectively fixedly connected to the corresponding two sides of the connecting end of the pipe pile. In practical applications, the lengths of the two branch chains 7 are equal.

[0035] Furthermore, a bolt rigging 5 is provided between each branch chain 7 and the pipe pile; a bolt hole matching the bolt rigging 5 is provided at a preset position of the connecting end of the pipe pile; and the bolt rigging 5 is fixed in the bolt hole.

[0036] Furthermore, to ensure a simple structure, the first traction chains 2 of this embodiment include two; one end of the two first traction chains 2 is connected to the towing equipment; the other ends of the two first traction chains 2 are respectively connected to the two ends of the crossbeam 3. It should be understood that the first traction chains 2 can also be three or more. Those skilled in the art can adjust the number of the first traction chains 2 according to the weight and number of the traction pipe piles. The two first traction chains 2 in this embodiment are equal in length.

[0037] Furthermore, the first traction chain 2 is connected to the towing equipment through the rigging 1 .

[0038] Furthermore, in order to facilitate the connection between the first traction chain 2 and the second traction chain 4 , a plurality of stiffening plates with through holes are provided on the cross beam 3 ; the through holes on the stiffening plates are used for connection with the first traction chain 2 and the second traction chain 4 .

[0039] Furthermore, in order to improve the structural strength, the cross beam 3 and the stiffening plate are formed in one piece.

[0040] Furthermore, it also includes an anti-collision fixture 6; the anti-collision fixture 6 is clamped and fixed on the pipe pile to prevent the pipe piles from colliding with each other.

[0041] The connection device of this embodiment is used in the construction process of hauling the PHC pile 8, and specifically includes:

[0042] After the PHC piles 8 are transported to the construction site, the pipe piles are dispersed near the pile foundation and then the piling operation is carried out.

[0043] The pipe piles are dispersed near the pile foundation. First, one end of the two first traction chains 2 is connected and fixed to the two ends of one side of the beam 3, and then the other ends of the two first traction chains 2 are connected to the towing equipment through the rigging 1; a plurality of second traction chains 4 are connected to the other side of the beam 3, and two branch chains 7 are arranged at the other end of each second traction chain 4. Bolt rigging 5 is arranged at the ends of the two branch chains 7. The bolt diameter of the bolt rigging 5 is adapted to the bolt hole size of the connecting end of the PHC pile 8. Each second traction chain 4 is responsible for towing a PHC pile 8. The two bolt riggings 5 ​​at the ends of the two branch chains 7 are respectively connected to the upper and lower bolt holes of the same PHC pile 8; the above steps are repeated until the other several bolt riggings 5 ​​on the beam 3 are connected to the corresponding PHC piles 8. Figure 2 As shown, after the connection is completed, the anti-collision fixture 6 is installed at the appropriate position of the multiple PHC piles 8 to prevent the other end of the PHC piles 8 from colliding and causing damage during the towing process.

[0044] After being towed to the pile foundation position, the fixture is taken out and the bolt rigging 5 is loosened until all the PHC piles 8 are dispersed near the pile foundation, and the pile spreading is completed.

[0045] Beneficial effects: The connecting device of the utility model has a light and simple structure, convenient and simple installation steps, low construction difficulty, high hauling efficiency, can effectively shorten the construction period, has good economic and social benefits, and has strong promotion and application value.
