Reversal rail hydraulic climbing form for concrete pouring of high and steep slope

Abstract

The invention relates to a reversal rail hydraulic climbing form for concrete pouring of a high and steep slope. The reversal rail hydraulic climbing form comprises a formwork (25), a traveling device and a rail (21), wherein the formwork (25) is loaded on the traveling device; the rail (21) is I-shaped; a rail support (20) is arranged at the lower part of the rail (21); anchor rods (19) inserted into a bedrock surface (24) are uniformly distributed at the bottom of the rail support (20); clamping holes are uniformly formed in the upper side of the rail (21); the traveling device consists of traveling wheels (1), a main shaft (4), an auxiliary shaft (7), reversal wheels (9), traveling clamping teeth (17), a hydraulic climbing oil cylinder (18) and a traveling bracket. According to the reversal rail hydraulic climbing form, the formwork can be pulled by a hydraulic system to automatically lift on a slope surface, the uplift pressure of concrete can be balanced by reversal wheel pressure, lifting positioning of the hydraulic oil cylinder can be realized by a special rail, the climbing form can be positioned by self-locking of grabbing teeth, and the problems of insufficient uplift pressure and difficulty in ascending movement of the concrete of the high and steep slope are avoided.

Description

technical field [0001] The invention relates to the development and construction technology of a sliding form system for concrete pouring of high and steep slopes in water conservancy and hydropower projects, in particular to a reverse rail hydraulic climbing formwork for concrete pouring of high and steep slopes. Background technique [0002] At present, in the concrete pouring construction of high and steep slopes of hydropower stations in my country, the conventional method is to use ordinary sliding formwork or safety formwork construction. For example: the left and right bank abutment slopes of the Changheba Hydropower Station have a large amount of concrete pouring, the slope ratio of the left and right banks is 1:0.95-1:0.5 (46.8°-63.16°), and the design block unit of the pressure plate is 16m* 20m, the poured concrete thickness is 50cm. Using ordinary trackless sliding form, it is necessary to install a hoist on the top of the slope to provide the lifting power of t...
