Pipeline corridor construction structure crossing track shield interval

Abstract

The invention provides a pipeline corridor construction structure crossing a track shield interval. The pipeline corridor construction structure crossing the track shield interval enables structural deformation of the track interval to be small, meets the requirement on track traffic normal operation, and enables the corridor structure to be easy in operation management and maintenance. The pipeline corridor construction structure crossing the track shield interval comprises construction wells, and a pipeline corridor between each two construction wells. The construction wells concretely comprise an original well and a plurality of receiving wells; the original well is used for initially positioning a position of the pipeline corridor; the receiving wells are used for gradually positioning during a pipeline corridor excavating process; a pit of the original well is reinforced; a back rest foundation of the original well is reinforced; an outlet foundation of the original well is reinforced; a first drilling pile enclosure is arranged at a side wall of the original well; a first triaxial mixing pile water-stop curtain is arranged at the outer side of the first drilling pile enclosure; a pit of each receiving well is reinforced; a second drilling pile enclosure is arranged at a side wall of each receiving well; and a second triaxial mixing pile water-stop curtain is arranged at the outer side of each second drilling pile enclosure.

Description

technical field [0001] The invention relates to the technical field of pipe gallery construction, in particular to a pipe gallery construction structure spanning a track shield section. Background technique [0002] The conventional pipe gallery construction across the track shield section adopts three-axis mixing pile foundation pit support, foundation reinforcement, foundation pit small-block construction, and construction monitoring. Due to the large deformation of the track section The normal operation of the traffic has had a relatively adverse impact. It is necessary to deal with the structural deformation of the rail transit to cause water leakage and to re-adjust and install the vehicle rails. Corridor construction. Contents of the invention [0003] In view of the above problems, the present invention provides a pipe gallery construction structure spanning the shield section of the track, which makes the structure deformation of the track section small, meets the...

Problems solved by technology

[0002] The conventional pipe gallery construction across the track shield section adopts three-axis mixing pile foundation pit support, foundation reinforcement, foundation pit small-block construction, and construction monitoring. Due to the large deformation of the track section structure, this construction structure has great impact on the track. The normal operation of the traffic has a relatively adverse impact, and it is necessary to deal with the structural deformation of the rail transit to cause water leakage and to re-adjust and install the vehicle rails. corridor construction
