Newly-built basement and existing subway station short underground passage structure and construction method thereof

Abstract

The invention provides a newly-built basement and existing subway station short underground passage structure. The newly-built basement and existing subway station short underground passage structurecomprises a plurality of horizontal beams and two ring beams. The horizontal beams extend in the excavation direction of an underground passage and are uniformly distributed on the upper side and theleft and right sides of an excavated section. The ring beams are located on the fracture surfaces of the two ends of the horizontal beams. The invention further provides a construction method of the newly-built basement and existing subway station short underground passage structure. Through the construction method, the problem of connection between a newly-built basement and an existing subway station is solved. The construction method belongs to the subsurface excavation method. A series of problems such as traffic congestion, the huge earth volume and high noise possibly caused by open excavation construction are avoided. The newly-built basement and existing subway station short underground passage structure provides a more secure working face for engineering construction and effectively enhances the stability of a tunnel.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering construction, and relates to a short underground passage structure and a construction method connecting two underground buildings, in particular to a short underground passage connection between a newly built basement and an existing subway station and a construction method thereof. Background technique [0002] With the development of society, people are using more and more urban space, and the development of society has caused serious congestion of the above-ground space in the city. Take advantage of it. Generally, high-rise and super high-rise buildings will be built with underground structures such as underground parking lots, underground commercial streets, underground supermarkets, etc. In order to alleviate traffic congestion in cities, subways have also been built, and subways are often connected with surrounding underground buildings. closely linked. However, the subwa...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing technology, the present invention provides a construction technology for connecting the newly built basement with the existing subway station, so as to solve the difficulty in the construction of the underground passage connecting the two underground buildings in the actual engineering construction, and there are great safety hazards in the tunnel construction problems and its stability, so that the actual construction of the project is more secure, etc.
