Ultralong concrete slip form body of concrete rockfill dam and construction method of slip form body

Abstract

The invention discloses an ultralong concrete slip form body of a concrete rockfill dam and a construction method of the slip form body. The slip form body comprises a fixed panel, a mobile panel and a positioning supporting plate, wherein scales are formed on the fixed panel; a slip form truss is arranged on the top surface of the slip form body; a slip form body panel is arranged on the bottom surface of the slip form body; a traveling bracket is arranged on the side surface of the positioning supporting plate. The construction method comprises the following steps: (1) performing construction preparation; (2) clearing a base layer, and performing acceptance check on the base layer; (3) performing surveying and setting out; (4) spray-coating emulsified asphalt; (5) binding steel bars, and keeping a side form be upright; (6) mounting a traction system; (7) mounting the slip form body in place; (8) erecting a sliding chute; (9) putting concrete into a bin for construction; (10) moving a slip form; (11) detaching the slip form; (12) maintaining the concrete. According to the method disclosed by the invention, the construction steps are simplified, the construction period is shortened, and the slip form construction on ultralong panel concrete is realized; therefore the construction steps are reduced, the construction progress is accelerated, and the economical and social benefits are obvious.

Description

technical field [0001] The invention relates to a super-long concrete sliding form body of a concrete rockfill dam and a construction method thereof. Background technique [0002] In recent years, the development of science and technology has driven the continuous progress of my country's economic construction, and various new technologies have been continuously applied to my country's construction projects. [0003] Slip form construction is a concrete casting process that can continuously form structures with a formwork device that can slide along the poured concrete surface, that is, on the ground according to the requirements of the plane and vertical dimensions of the structure, with the aid of crawling on the support rods The lifting machine is lifted, and the cycle operation of steel bar binding, concrete pouring and formwork lifting is carried out to realize the construction of tall structures. [0004] The dam slope construction in the prior art is mainly aimed at ...

AI Technical Summary

Problems solved by technology

[0004] The dam slope construction in the prior art is mainly aimed at the construction of the shorter dam slope, but there are few super-long concrete construction techniques for rockfill dams, and due to the long slope, the traditional slope construction is difficult to meet its construction requirements. Requirements; due to the long slope, the overall layout and structural strengt
