Adjustable inverted arch type supporting component for tunnel and bridge construction and using method of adjustable inverted arch type supporting component

Abstract

The invention relates to the technical field of tunnels, in particular to an adjustable inverted arch type supporting component for tunnel bridge construction and a using method thereof, and solves the problems that in the prior art, all inverted arch type supporting components are independent mechanisms and cannot be combined with connecting structures to support internal extension parts, so that the steel consumption is large, combined supporting is inconvenient, and the construction cost is low. And the stress characteristic of the supporting piece is not fully exerted. The invention discloses an adjustable inverted arch type supporting component for tunnel and bridge construction and a using method thereof, the adjustable inverted arch type supporting component comprises a tunnel, two supporting mechanisms and a plurality of supporting modules arranged in the tunnel, each supporting module comprises a connecting mechanism and an assembling extension mechanism, and each supporting mechanism comprises a base. The supporting structure is reasonable in structure, the two ends of the interior of the tunnel are supported only through the two inverted arch type supporting structures, the middle section of the tunnel is supported in a butt joint mode through the light-weight supporting modules, interconnection supporting can be achieved, and the stress characteristic of the supporting structure is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of tunnels, in particular to an adjustable reverse arch type supporting member for tunnel bridge construction and a method for using the same. Background technique

[0002] With the development of my country's urban economy, a large number of urban population has been concentrated, which has caused huge pressure on public transportation. The problem of urban traffic congestion is not uncommon, which seriously restricts the further development of the city. In order to solve the urban traffic problem, a large number of overpasses and viaducts have been built. However, because the ground bridges have a greater impact on the urban environment and reduce the use value of the surrounding land, bridges across rivers and rivers also have an impact on the waterway. At the same time, in order to solve the problem of air defense, many cities have turned traffic underground, and built underground interchanges, subways a...
