Prefabricated energy pipe pile joint

Abstract

The invention relates to a prefabricated energy pipe pile joint. The pipe pile joint comprises a hook part arranged on an upper pile section and a slot part arranged on a lower pile section, wherein the hook part comprises a plurality of hook bodies arranged on the lower end face of the upper pile section at intervals; the top ends of main bodies of the hook bodies can be arranged on the upper pile section in an axial up and down movement manner; the bottom ends of the main bodies extend downwards vertically and are bent upwards to form hooks; the slot part comprises a plurality of notches formed in the lower pile section; the notches correspond to the hook bodies one to one; a plurality of upper openings penetrating in an axial direction of the upper pile section are formed in the upper pile section; a plurality of lower openings penetrating in an axial direction of the lower pile section are formed in the lower pile section; the upper openings correspond to the lower openings one toone; and one upper opening and one corresponding lower opening penetrate vertically to form a channel allowing a pipeline to pass through. According to the joint, a pipe pile is connected by a mechanical connecting structure; and the joint is not influenced by worker operation, and has the advantages of convenience and good connecting effect.

Description

technical field [0001] The invention belongs to the field of pile foundation engineering, and in particular relates to a prefabricated energy pile pipe pile joint. Background technique [0002] Based on the consideration of the use of underground space, engineers and technicians combined ground source heat pumps with building pile foundations to propose a technical solution for energy piles. At present, due to the imperfection of the market, energy piles have not been widely laid, and most of the current domestic pipe piles are spliced ​​on site. Ordinary prefabricated pipe piles are not equipped with corresponding heat exchange pipe ports, and the current pipe pile connection work mostly uses welding to connect two pipe piles, which is time-consuming, and the construction quality is limited by the welding of on-site workers. Unevenness affects the quality of pipe piles. [0003] Chinese patent CN105525612A discloses a high-efficiency pipe pile joint. The upper and lower p...
