Abstract

The invention discloses a temporary supporting system and an application method thereof, and relate to the technical field of underground engineering construction. The system and the application method aim to solve the problems that an existing temporary support is erected through field welding, disassembly and assembly difficulty is high, component connection precision is poor, vertical displacement adjustment cannot be achieved and recycling cannot be achieved. The system comprises at least one pair of sliding rails which are laid at the bottom face of an excavated space in the length direction of pipe roofing, a plurality of temporary supporting devices which are arranged on the sliding rails and slide along the sliding rails, and a plurality of vertical displacement compensation devices. The temporary supporting devices are of a rectangular framework structure formed by connecting at least four supporting unit combination components through bolts. The top of each supporting unit combination component is provided with one vertical displacement compensation device, the tops of the vertical displacement compensation devices abut against horizontal supports, and the bottoms of allthe supporting unit combination components can slide along the sliding rails.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to a temporary support system used in the construction of pipe curtains in underground spaces in soft soil areas and its application method. Background technique [0002] The pipe curtain method is a new type of underground excavation construction technology. Its construction principle is to use pipe jacking equipment to jack steel pipes into the soil between the originating shaft and the receiving shaft, and the steel pipes are connected by locks to form a pipe row. , and inject a water-stopping agent into the lock gap to meet the water-stopping requirements, and then construct an underground structure under the protection of the pipe curtain. [0003] At present, during the excavation of the earthwork under the pipe curtain, temporary supports made of steel or steel pipes are mostly used. The temporary supports are generally erected by on-site welding....
