Single-side side wall slip form and construction method

Abstract

Single-sided side wall slip form and construction method. The sliding form is composed of formwork, lifting frame, back flute, platform, back connection, guide rail, guide wheel mechanism, hydraulic jack, limit leveler, climbing rod, pipe frame and bolt connection. The face plate of the formwork is welded to the web, the web is opened with bolt holes, and hung on the back corrugation, which is grooved and made of steel, 34 templates are connected into a 30m formwork group, with a slope of 0.3% to 0.5%; the lifting frame is formed by a groove It is made of steel and angle steel connection; the back connection is steel plate; the formwork, platform, back connection and lifting frame are connected as a whole, and connected with the hydraulic jack to drive the sliding form to rise; the diagonal brace is connected to fix the lifting frame and the lower back corrugated; the guide rail is made of channel steel , welded with the rock wall anchor rod; the guide wheel mechanism is composed of a guide wheel, a bracket, and a shaft, which is installed between the back corrugated, and the shaft connects the bracket and the guide rail; the climbing rod is made of steel pipes, and the jack climbs along it; limit leveling The climber adjusts the climbing position; the pipe frame ensures the stability of the climbing pole. The construction method is that the sliding form is poured while climbing, and the concrete is formed at one time.

Description

1. Technical Field [0001] The invention belongs to the technical field of hydropower engineering, and specifically relates to construction equipment and methods for underground concrete pouring of large hydropower projects. 2. Background technology [0002] The concrete pouring of the single-sided side wall of the underground gate pier chamber of the large hydropower project used traditional small formwork to carry out the concrete pouring construction in the past in China. The process is more complicated, a lot of money and manpower are invested, and the construction period is long. Considering the Xiluodu project, the size of a single-sided high side wall is approximately, length: 84m, height: 57m. The size of the traditional small formwork is generally: length: 1.5m, width: 0.3m, generally rectangular. Due to inevitable errors during manufacturing and installation, the quality of the cast is not high. As far as the pouring process is concerned, due to the limitation of the si...
