Construction method for dismounting reinforced concrete supporting beam with assistance of hydraulic lifting bearing platform

Abstract

The invention discloses a construction method for dismounting a reinforced concrete supporting beam with the assistance of a hydraulic lifting bearing platform. The construction method comprises the following steps: S1, the hydraulic lifting bearing platform is moved to a position right below one segment beam, and a hydraulic lifting device is started to support the segment beam; S2, fixing framesare mounted right below other segment beams, and the segment beams are supported by the fixing frames; S3, the segment supported by the hydraulic lifting device is cut and separated from the reinforced concrete supporting beam; S4, the hydraulic lifting device is started to lay down the segment beam separated from the reinforced concrete supporting beam in step S3; S5, the segment beam laid downin step S4 is removed, the fixing frame close to one side of the hydraulic lifting bearing platform is dismounted, the hydraulic lifting bearing platform is moved to a position right below the segmentbeam above the dismounted fixing frame, and the hydraulic lifting device is started to support the segment beam; and S6, step S5 is repeated till all the segment beams are cut and removed. Accordingto the construction method, the hydraulic lifting bearing platform is adopted as an auxiliary support, thereby achieving the advantage that the dismounting efficiency and safety can be improved.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a construction method for assisting the removal of reinforced concrete support beams by a hydraulic lifting load-bearing platform. Background technique [0002] In the process of urban construction, there are more and more deep foundation pit projects under complex terrain environment. In order to protect the safety of the surrounding buildings (structures) and the structure of the deep foundation pit itself, the deep foundation pit must be effectively supported during the construction process, and it is often necessary to set up an enclosure around the deep foundation pit. Reinforced concrete support beams are widely used in deep foundation pit enclosure structures because they can effectively control the deformation of foundation pits. In the process of restoration of foundation pit structures, reinforced concrete support beams need to be removed. However, due...

However, due to the complexity of the construction project, the demolition of the reinforced concrete support beams will have an adverse impact on the surrounding environment

The traditional method of removing reinforced concrete support beams with steel pipe scaffolding as the load-bearing system has some disadvantages. For example, the construction cost of steel pipe scaffolding is high, it needs to be erected and dismantled repeatedly, the turnover is troublesome, the construction noise is large, and the dust is large.
