Abstract

The invention provides a prestressed pipe pile reinforcement cage support plate blockage device. The device comprises a pipe pile, a ring main body, a blockage ring, a reinforcement cage support plateand a bottom tray; the ring main body, the blockage ring, the reinforcement cage support plate and the bottom tray are arranged in the pipe pile; the bottom tray is of a cylindrical cavity structureopened at the top; a spiral projection is arranged on the outer side surface of the bottom tray; the reinforcement cage support plate is of a disc structure, and is annularly arrayed with multiple longitudinal reinforcements extending up; the ring main body is of a cylindrical cavity structure opened at the bottom; a spiral groove matched with the spiral projection is formed in the inner side surface of the ring main body; multiple holes are annularly arranged at the top of the ring main body; the holes are adapted to the longitudinal reinforcements in position; and the blockage ring is of a horn structure and arranged on the outer side of the ring main body for preventing formation of a gap with a certain width between the inner wall of the pipe pile and the reinforcement cage support plate to prevent leakage of core filling concrete during casting.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prestressed pipe pile reinforcement cage support plate sealing device. Background technique [0002] In foundation and foundation subdivision projects, when prestressed high-strength concrete pipe piles are used in the design, it is often necessary to set a round thin steel supporting plate with a bottom of 4-5 mm on the top of the pile, and weld longitudinal reinforcement on the supporting plate. Set up the spiral stirrup, and then pour the core concrete. During the construction process, often due to the extremely narrow working space and the size deviation of the inner wall of the prestressed pipe pile hole and the diameter of the steel cage supporting plate, a gap of a certain width is formed between the inner wall of the pipe pile and the supporting plate, and the core-filled concrete is very easy to pour. Leakage. Leakage not only causes a waste of concrete...
