A prestressed pipe column pile connecting device and its construction method

Abstract

The application relates to a prestressed pipe column pile connection device and its construction method, which includes a mounting plate and two movable flaps that are symmetrically hinged on the mounting plate and adapted to the size of the pipe string. The movable ends of the two movable flaps are provided with useful For the connection assembly connecting two movable flaps, one end of the movable flap is connected with a guide flap, and the guide flap is enlarged away from the opening of the movable flap, and an extrusion rod is installed on the inner wall of the movable flap sliding along the length direction of the mounting plate. The driving device is used to drive the extrusion rods on the two movable flaps to slide synchronously and reversely along the length direction of the mounting plate. When connecting piles to the pipe string, turn the two movable flaps on the installation plate to surround the pile at the lower section, then connect and fix the movable ends of the two movable flaps, and then drive the extrusion rods on the two movable flaps toward the pipe synchronously. The pile moves and presses against the pipe pile, and then the upper pipe is inserted from above the guide valve to quickly align the upper end pile with the lower end pile. This application has the effect of convenient operation and improved pile connection quality.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a prestressed pipe column pile connecting device and a construction method thereof. Background technique [0002] Prestressed concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles. Pretensioned prestressed pipe piles are hollow cylinders made by pretensioning prestressing technology and centrifugal forming method Slender concrete prefabricated components, mainly composed of cylindrical pile body, end plate and steel ferrule. [0003] The patent with authorized notification number CN100580191C discloses a construction method of high-definition prestressed concrete pipe piles, including setting the pile driver in place after measuring and setting out the wires, lifting the prefabricated pile with the pile driver after the inspection of the prefabricated pile, and after stabilizing the pile, installing the...

Problems solved by technology

[0004] Regarding the above-mentioned related technologies, there are the following defects: in order to avoid the axis deviation of the upper and lower pile joints during the entire pile connection process, it is often necessary to use measuring instruments to monitor and manually adjust, the construction efficiency is low and the quality of pile sinking cannot be guaranteed
