Problems solved by technology

[0003]At present, the joint connection between prefabricated caps and pipe piles mostly adopts screw and bolt connection structure to connect prefabricated caps and prefabricated pipe piles together. There are several threaded holes, and the corresponding threaded holes are opened on the cap, and the prefabricated cap is placed on the upper side of the pipe pile, so that the threaded holes on the cap are aligned with the threaded holes on the pipe pile, and the bolts are inserted from the upper side of the cap , screwed into the threaded hole on the pipe pile, which requires that when placing the cap, the threaded hole on the cap should be completely aligned with the threaded hole on the pipe pile. The operation of lifting and adjusting the position is difficult in construction and low in installation efficiency

Abstract

The invention provides a connecting structure of a tubular pile and a prefabricated bearing platform and a mounting construction method of a tubular pile and a prefabricated bearing platform. The connecting structure of a tubular pile and a prefabricated bearing platform comprises a tubular pile and a bearing platform, a sealing plate is arranged in the tubular pile, the connecting structure further comprises a clamping assembly and a connecting rod, one end of the connecting rod is connected with the bearing platform, and the other end of the connecting rod protrudes out of the lower side of the bearing platform; the clamping assembly comprises two clamping pieces which are arranged on the upper portion of the tubular pile and rotationally connected with the tubular pile, and the clamping pieces are used for clamping the connecting rod; when the connecting rod is inserted into a clamping groove to a preset position, the two clamping pieces rotate relative to the tubular pile to clamp the connecting rod; and according to the mounting construction method of a tubular pile and a prefabricated bearing platform, the connecting structure of a tubular pile and a prefabricated bearing platform is used for mounting.

Description

technical field [0001] The invention belongs to the technical field of transmission line pile construction, and in particular relates to a connection structure between a pipe pile and a prefabricated cap and an installation and construction method for the pipe pile and the prefabricated cap. Background technique [0002] The transmission lines are arranged in dotted lines, and the traffic conditions and environmental conditions are poor. This kind of decentralized and multi-regional operation requires portable construction equipment and miniaturized foundation size. The load transmitted through the tower to the foundation, the foundation can meet the safe, reliable and stable operation of the transmission line. The pile foundation cap connections of existing transmission lines are mostly formed by cast-in-place technology. The cast-in-place technology is relatively mature, but the cast-in-place method not only pollutes the environment, but also increases manpower input and i...
