Description

Connection structure of adjacent tubular piles Technical Field The utility model belongs to the technical field of constructional engineering, and particularly relates to a connecting structure of adjacent tubular piles. Background In building pile foundation engineering, precast piles become widely used piles because of being capable of bearing large loads, being firm and durable and being high in construction speed. The length and the section of the reinforced concrete precast pile can be selected according to the requirements in a certain range, and the precast pile can ensure the manufacturing quality due to the prefabrication on the ground, has high bearing capacity and good durability, and is particularly widely applied to engineering. However, the pile length of the factory precast pile is generally not more than 12m, and when the pile length required by engineering exceeds the range, the pile length is prefabricated in sections and then lengthened in the piling process. In the construction process, the condition that the pile length is insufficient often occurs, and a pile is welded usually, so that after the embedded part on the surface of the precast pile is cleaned, the precast pile of the upper section and the precast pile of the lower section are welded firmly. However, the welding process needs professional welding personnel to operate, the welding quality requirement is higher, and if the welding is not firm, hidden dangers such as pile body fracture easily occur. Disclosure of utility model In view of the above-mentioned drawbacks of the prior art, an object of the present utility model is to provide a connection structure of adjacent tubular piles, which is used for solving the problems of complex pile splicing operation and low construction efficiency in the prior art. In order to achieve the above and other related objects, the present utility model provides a connection structure of adjacent tubular piles, including a plug rod, the plug rod is made of thermoplastic metal, the plug rod is fixedly arranged at an end portion of one of pile bodies, the pile body provided with the plug rod is a first pile body, and the plug rod protrudes out of the first pile body; The jack is arranged at the end part of the other pile body, the pile body provided with the jack is a second pile body, the inner wall of the jack is provided with an engagement limiting surface, the length of the inserted link protruding out of the first pile body is a, the depth of the jack is b, and a is larger than b; The inserted link is heated to a plastic state and is inserted into the jack, so that the outer wall of the inserted link is attached to the occlusion limiting surface, and the axial movement of the inserted link is limited.
