Auxiliary device for preventing deformation of adjacent building foundation of urban railway

Abstract

The invention discloses an auxiliary device for preventing deformation of adjacent building foundation of an urban railway. The auxiliary device comprises a base, wherein a fixing block is welded to the middle of a top end of the base, a plurality of inserting grooves are formed in the middle of a top end of the fixing block at equal intervals, balancing weights are embedded into the inserting grooves, and a wedge-shaped block is arranged on one side of the fixing block; a plurality of limiting grooves are formed in a bottom end of the wedge-shaped block at equal intervals, a plurality of limiting blocks are fixedly arranged on one side of the base at equal intervals and connected with the corresponding limiting grooves in an embedded mode, a plurality of sliding grooves are formed in the other side of the top end of the base at equal intervals, sliding blocks are slidably connected into the sliding grooves, and fixing rings are fixedly installed on one sides of the sliding blocks. By means of the fixing blocks and the wedge-shaped blocks arranged at the top end of the base, auxiliary supporting can be conveniently conducted on the foundation on the side face, by means of the balancing weights embedded in the fixing blocks, the supporting strength is increased, stability of the foundation is guaranteed, and it is avoided that normal running of urban railways is affected by collapse of the foundation.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to an auxiliary device for preventing foundation deformation of adjacent buildings on urban railways. Background technique [0002] Urban (suburban) railway: also known as commuter railway and suburban railway, refers to the passenger rail transit system within the metropolitan area, serving cities and suburbs, central cities and satellite cities, and key towns, etc., and the service scope is generally within 50 ---Within 100 kilometers, the station distance is short and the density is high. The design speed should be 100-160 kilometers per hour, and the average station spacing should not be less than 3 kilometers in principle. Urban rail transit belongs to the category of generalized urban rail transit.

Problems solved by technology

[0003] During the construction of existing urban railways, due to the influence of buildings, the side foundations are prone to deformation, which affects the service life of urban railways. At present, the way to deform the foundations is to pile up stones. Due to the poor drainage effect, long-term The erosion of rainwater will easily lead to loose piles and deformation of the foundation. Another way is to pour concrete with steel bars. Although this problem can be solved, it is costly. Therefore, it is necessary to design an auxiliary device for urban railways to prevent foundation deformation of adjacent buildings.
