Abstract
The invention discloses a comprehensive pipe gallery structure of a mountain tunnel suitable for a new Austrian tunneling method. The cross section of the pipe gallery structure is in a city-door holeshape; an interlayer plate extending in a length direction is arranged in the pipe gallery structure; the lower side of the interlayer plate and the side walls of two sides and the bottom, corresponding to the rectangular structure, of the pipe gallery structure encircle a comprehensive cabin, the cross section of which is rectangular; a compartment plate is arranged between the upper side of theinterlayer plate and the top of the pipe gallery structure to divide an upper layer into a gas cabin and a sewage cabin; a fireproof partition is arranged in the gas cabin; the gas pipeline is arranged in an area encircled by the tops of the fireproof partition, the compartment plate and the pipe gallery structure; an area encircled by the fireproof partition and the tops of the fireproof partition, the compartment plate and the pipe gallery structure is an air inlet channel; and the air inlet channel can be used for escaping. By applying the comprehensive pipe gallery structure, the lower layer of the pipe gallery is designed rectangularly, so that more pipelines can be accommodated as the lower space of the pipe gallery is optimized under a condition of not increasing the amount of excavation, and it is convenient to mount and overhaul the pipelines.
Description
technical field [0001] The invention relates to the technical field of pipe gallery construction, in particular to a mountain tunnel comprehensive pipe gallery structure suitable for construction by the new Austrian method. Background technique [0002] The comprehensive pipe gallery refers to a modern and intensive urban infrastructure formed by concentrating two or more municipal pipelines in the same artificial space. The construction of a comprehensive pipe gallery can minimize the "zipper" excavation of the road surface, prolong the service life of the pipeline, solve the problem of tight routing, and reserve space for uncertain pipelines. [0003] In the prior art, the common methods of trenchless construction of comprehensive pipe gallery include shield method and new Austrian method. Common cross-sections of the tunnel comprehensive pipe gallery constructed by the new Austrian method are oval, horseshoe and so on. [0004] However, the lower section of the existing...
