Abstract

The invention relates to a tunnel, in particular to a symmetric horseshoe-shaped assembled concrete tunnel. Flanges on the two sides of a top-arched shell plate and a bottom-arched steel plate are inoverlapped connection with two vertical shell plates correspondingly through flanges of the shell plates, and the bottom-arched shell plate is in overlapped connection with the vertical shell plates through the flanges, so that a horseshoe-shaped concrete plate is formed. Integrated assembling and production can be carried out, and industrial chain formation, production line production and construction are facilitated. The connection of the components is simpler and more effective, the stress performance is good, the stability is high, the application range is wide, the construction speed is high, the economic effect is good, the complex operation in the construction process is avoided, the cost can be greatly reduced, and the transportation and field assembly are easy.

Description

technical field [0001] The invention relates to a tunnel, in particular to a symmetrical horseshoe-shaped fabricated concrete tunnel. Background technique [0002] A tunnel space is built underground in the city, which integrates various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., and has special inspection ports, hoisting ports and monitoring systems, and implements unified planning, unified design, and unified construction Management and management are the important infrastructure and "lifeline" to ensure the operation of the city. The construction of the comprehensive pipe gallery avoids the impact and interference on traffic and residents’ travel caused by frequent excavation of roads for laying and maintenance of underground pipelines, and maintains the integrity and beauty of the road capacity. It reduces the cost of multiple renovations of the road surface and the maintenance cost of engineering pipelines. Maint...
