Abstract

Provided is a hydraulic self-elevated truss-type cantilever heavy arch dammould system,hydraulic self-elevated truss-type cantilever heavy arch dammould system comprisesforced tripods, a hydraulic climbing frame system connected with the forced tripods and a mould device movably arranged on the forced tripods. A plurality of the forced tripods are fixedly connected with each other through a plurality of tripod connection beams. The back face of themould device is provided with a plurality of crosswisewalings.The crosswisewalings are connected with truss-type lengthwise walings. The truss-type lengthwise walings are connected with one end of a sliding rod member through an adjustable shaft rod of the mould. The other end of the sliding rod member is connected with the bottom of the truss-type lengthwise walings through a connecting module which is connected with the force tripods. The sliding rod member is also connected with the top of the force tripods through a telescoping drive device. By adopting the unique truss-type lengthwise walings and matching with a mould releasing and clamping structure, mould forming and releasing are convenient, the height of poured concrete in each bunker is increased and the connection with an anchor cone is convenient so as to adapt to the complex curved surface shapeof the arch dam.

Description

technical field [0001] The invention relates to an arch dam construction formwork, in particular to a hydraulic self-elevating truss type cantilever heavy arch dam formwork system. Background technique [0002] For a long time, the formwork used for concrete pouring of arch dams has been a crane-lifted common dam formwork. Under normal construction conditions, this formwork system can meet the construction requirements of arch dam concrete. However, once the arch dam is in a perennially windy environment or the lifting means are insufficient, the construction safety and construction efficiency of ordinary dam formwork will greatly affect the arch dam concrete construction work. The self-climbing dam formwork technology can well solve the above-mentioned problems of common dam formwork. However, during the climbing process, the automatic climbing formwork technology requires the formwork slab surface to be separated from the concrete surface by a certain distance (about 300m...
