Integrated structure capable of improving cutting efficiency and cutting method

Abstract

The invention provides an integrated structure capable of improving the cutting efficiency and a cutting method. The structure comprises a station frame of a double-layer and double-column three-stride rectangular frame structure, a side wall fixed to one side of the station frame, a station side wall waterproof layer fixed between the station frame and the lower end of the side wall, a shared fender post, a lap joint layer and a shear wall, a foundation pit frame, a foundation pit waterproof layer and a crown beam. The shared fender post, the lap joint layer and the shear wall are fixed to the right side of the side wall, the foundation pit frame is fixed to the right sides of the shared fender post, the lap joint layer and the shear wall, the foundation pit waterproof layer is fixed to the shear wall and the foundation pit frame, and the crown beam is fixed to the top end of the shared fender post. The integrated structure can achieve the purposes that the structure is simple, and the manufacturing cost is saved; and the underground space is effectively utilized, and the space utilization rate is increased.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to an integrated structure and a cutting method that can improve cutting efficiency. Background technique [0002] With the gradual and in-depth development of integrated development and intensive utilization of urban underground space, more and more subway stations have begun to implement integrated construction with adjacent commercial buildings. The integrated construction mode of the subway station and the surrounding underground space is to combine the subway station with the surrounding underground space, design, plan and carry out the construction in stages in a unified manner. In order to save costs and effectively utilize the underground space, subway stations generally share enclosure piles with the integrated structure. After the construction of the subway station and the integrated structure is completed, the shared enclosure piles are chiseled at the connection openin...

AI Technical Summary

Problems solved by technology

The disadvantage of this pile cutting scheme is that since the station side walls and integrated structure side walls on both sides of the shared pile have been formed, the construction space for cutting piles is narrow, (the working width is the diameter of the pile + the blocks outside the station side wall Thickness), it is difficult for large equipment to enter the working surface, mainly relying on manual chiseling to remove the surrounding protection piles, the construction efficiency is low, and the pile cutting operation period is long

If the construction of pile cutting is arranged after the construction of the integrated structure is completed, it will inevitably affect the scheduled operation of the subway station
