Steel pipe full-encapsulating concrete pouring pipe stabilization supporting structure and construction method thereof

Abstract

The invention provides a steel pipe full-encapsulating concrete pouring pipe stabilization supporting structure and a construction method thereof. The steel pipe full-encapsulating concrete pouring pipe stabilization supporting structure comprises a flat top-shaped buttress and a pipe stabilization bracket; the pipe stabilization bracket comprises two oppositely arranged counter-pulled brackets and a pull rod which is adjustable in length and is connected between the counter-pulled brackets; each counter-pulled bracket is provided with an arch-shaped steel plate; and the radian of each arc isconsistent to the radian of the steel plate, wherein the steel plates are collaboratively supported and positioned by at least two buttresses and at least two auxiliary pipe stabilization brackets, and the end part of each steel pipe extends out of the buttress with a certain length. By adopting the technical scheme of the invention, the mounting progress of the steel pipe can be guaranteed, and two parameters, including an elevation and an axis position, of the accuracy are separately controlled; as the buttress is in a flat top shape, curve surface construction can be reduced, the elevationand the axis position can be conveniently regulated on the flat top-shaped buttress, and the accuracy is easily ensured; and the pipe stabilization bracket is adopted to limit the axis position, and limitation is convenient and accurate.

Description

Technical field [0001] The invention relates to a stable pipe supporting structure used for steel pipe full-encapsulation concrete pouring and a construction method thereof. Background technique [0002] In recent years, my country's hydropower projects have gradually increased, and the installation and construction of penstocks in hydropower projects is essential. At present, pipeline construction tends to be long-distance, large-diameter, large-capacity, high-pressure, and high-quality steel. The installation of penstocks is an important part of quality control in the construction of water conservancy and hydropower projects, and the accuracy of pipe stabilization during the installation process has a great impact on the construction quality of pipeline installation, and the construction quality of pipeline installation also affects the stability and safety of the operation of water conservancy and hydropower projects. [0003] At this stage, the stabilized pipes before pouring ...

AI Technical Summary

Problems solved by technology

[0006] (1) The radian of the pier is difficult to control, resulting in low installation accuracy; once the enclosed reinforced concrete pier is cast, the installation accuracy is not easy to adjust

[0007] (2) In order to prevent the damage of the steel pipe, a polyethylene closed-cell foam board is placed on the top of the pier, thereby increasing the project cost;

[0009] (4) It is easy to damage the outer anti-corrosion of the steel pipe during the placement of the steel pipe
