Abstract

The invention discloses a corrugated steel outside lining concrete structure for an underground utility tunnel and relates to underground utility tunnel structures. The problems that existing concretestructures are poor in foundation differential settlement resistance and seepage resistance, fracture and water leakage of connectors of prefabricated tunnels are liable to occur, and corrugated steel tunnel structures are inadequate in stable bearing capacity are solved. The corrugated steel outside lining concrete structure for the underground utility tunnel comprises an outer lining reinforcedconcrete ring, an arch corrugated steel plate and a bottom plate, wherein the outside lining concrete ring covers the outer plate face of the arch corrugated steel plate to form an arch; cup openinggrooves are formed in the transverse left side and the transverse right side of the bottom plate correspondingly; studs are arranged at arch springs of the arch corrugated steel plate; the arc springsare inserted into the cup opening grooves; post-cast arc spring concrete is arranged in the cup opening grooves; and the periphery of the arch and the bottom plate is wrapped with surrounding soil. The corrugated steel outside lining concrete structure is higher in construction speed, and the seepage resistance, the foundation differential settlement resistance and prefabricated section connection convenience of the structure are greatly improved.

Description

technical field [0001] The invention relates to an underground comprehensive utility gallery structure. Background technique [0002] With the construction process of my country's modern cities and the increase in population and development intensity, the city's demand for municipal pipelines is getting higher and higher, and the number is increasing. The traditional method of laying municipal pipelines has been unable to meet the demand. Years of practical experience abroad have proved that the construction of urban underground comprehensive pipe corridors can solve problems such as repeated excavation of road surfaces, dense overhead line networks, and frequent pipeline accidents, which is conducive to ensuring urban safety, improving urban functions, beautifying urban landscapes, and promoting urban intensification Efficient and transformational development is conducive to improving the city's comprehensive carrying capacity and the quality of urbanization development, an...
