Abstract

The invention relates to the technical field of bridge construction, in particular to a construction method for in-situ removal of an ascending mobile formwork. The method includes: S1, removing the bridge of the nose; S2, dividing the unit body and the sub-unit body; S3, removing the sub-unit body, the upper beam and the main beam in order to complete the removal of the unit body; S4, in order from back to front Each unit body is dismantled until all the unit bodies are completely dismantled; S5, removing the middle outrigger. The method is scientific and reasonable, the construction steps are simple, the construction efficiency is high, the original operation performance of the equipment is not damaged, and the demolition operation process is highly safe, economical and practical.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction method for in-situ removal of an ascending mobile formwork. Background technique [0002] The mobile formwork is a self-propelled special equipment for bridge construction with its own formwork, supported by caps or pier columns. The existing patent document (ZL201510585742.X) discloses an upward mobile formwork, which mainly includes main beam, nose bridge, upper beam, hanging beam, front outrigger, middle outrigger, middle trolley, rear sliding beam, etc. There are corresponding hydraulic and electrical systems. The upward moving formwork has the advantages of simple equipment and technology, safe construction, high degree of mechanization, short construction period and stable construction quality. With the development of our country's transportation industry, the upward mobile formwork construction method will be widely used in bridge construction....
