Abstract

The invention discloses a shield pipe rack system and a construction method thereof. The shield pipe rack system comprises a pipe rack main line formed through splicing of a plurality of shield pipe rack standard sections in the longitudinal direction or formed by one shield pipe rack standard section. A shield origination well and a shield termination well are arranged at the two ends of the shield pipe rack standard section correspondingly, and a plurality of pipe rack comprehensive joint units are arranged on one side of the exterior of the pipe rack main line at intervals; and the pipe rack comprehensive joint units can communicate with the pipe rack main line through pipe rack connecting sections, and one ends, away from the pipe rack comprehensive joint units, of the pipe rack connecting sections can be sealed, and can be provided with connecting section separation plates in an opened mode. According to the shield pipe rack system and the construction method thereof, the problemsthat the construction period is long, the pipe rack comprehensive joint construction space is limited, and the construction cost is high existing in the prior art are solved, the construction relation degree of a shield line and the pipe rack comprehensive joint units can be reduced, the overall construction period of the shield pipe rack system is shortened, the advantage of shield pipe rack long-distance implementation can be sufficiently developed, and the construction cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of urban comprehensive pipe gallery, in particular to a shield pipe gallery system and a construction method thereof. Background technique

[0002] As a form of municipal pipeline laying, the comprehensive pipe gallery technology has received extensive attention, and there are very mature cases in various countries. In particular, the construction of comprehensive pipe corridors in my country has developed rapidly in recent years. The construction of comprehensive pipe corridors in new urban areas often faces special environments, as follows Large-scale excavation construction methods are limited for rivers with relatively large cross-sections, railways, expressways, existing long-distance pipelines such as water transportation, gas transportation, and oil transportation, and trenchless construction methods must be used; for the construction of existing urban areas Comprehensive pipe corridors often have many ...
