The invention discloses a directed lossless static-force cutting dismounting method for a reinforced concrete plate, and relates to the technical field of concrete structure dismounting. The method comprises the following steps that (1) a concrete plate to be dismounted is defined, and divided into sub concrete plates arranged adjacent to the free face; (2) rope through holes are drilled in the sub concrete plates respectively; (3) the peripheries of the sub concrete plates are cut successively, and before that the sub concrete plates are disengaged by cutting, lifting ropes penetrate the ropethrough holes of the sub concrete plates for fixation; and (4) the sub concrete plates disengaged by cutting are placed to specific positions via the lifting ropes. Thus, stable cutting and dismounting of the sub concrete plates are maintained, dismounting is stable, influence on the surrounding is less, and construction is safe.
Description
technical field [0001] The invention relates to the technical field of demolition of concrete structures, in particular to a treatment method for directional non-destructive static cutting and demolition of reinforced concrete slabs. Background technique [0002] In the construction process of building foundation engineering, it is often encountered that there is a conflict between the tower crane equipment and the multi-layer support concrete structure sealing plate of the foundation pit support in space, and the multi-layer support concrete structure constructed during the foundation pit support needs to be removed. [0003] At present, there are two conventional demolition methods for concrete structures: manual chisel removal and mechanical chisel removal. Manual chisel removal workers have high labor intensity, high safety risks, poor working environment, and low construction efficiency; mechanical chisel removal is more efficient than manual chisel removal. , but the c...
