Large-diameter shield machine synchronous concrete inverted arch paving device and method

Abstract

The invention provides a synchronous inverted-arch concrete paving device and method of large-diameter shield tunneling machine. The device comprises a trestle, wherein inclined wheel pairs are arranged at the bottom part of the trestle, rails are paved on the trestle, an inverted-arch paving mold is mounted at the bottom part of the trestle, and a slag collection hopper is arranged at the front part of the inverted-arch paving mold; the inverted-arch paving mold comprises side seal plates and a top part seal plate, the left side seal plate and the right side seal plate are connected by a tensioning adjusting device; a vertical limit oil cylinder at the bottom part of the trestle is connected with the top part seal plate; a horizontal oil cylinder is further arranged at the bottom part of the trestle, and connected with a boots plate; side seal plate limit oil cylinders for limiting side seal plate guide wheels are further arranged on the two sides of the trestle, the side seal plate guide wheels are connected with the side seal plates, and the side seal plates are connected with the trestle through top part seal plate guide wheels. The device achieves synchronous tunneling construction, and inverted-arch pouring and filling by pertinently designing a rear supporting system and the inverted-arch trestle of the tunneling machine, thereby improving the mechanical degree of inverted-arch pouring, shortening the construction period of the tunnel construction project, and improving the construction efficiency.

Description

technical field [0001] The invention relates to the field of special mechanical equipment for tunnels, in particular to concrete invert filling equipment, which realizes synchronization of invert filling and shield tunneling. Background technique [0002] The shield method has the advantages of little impact on the surrounding environment, high degree of automation, fast construction, high quality and high efficiency, safety and environmental protection, and is suitable for tunnel construction with poor geological conditions and high settlement requirements. With the development and maturity of shield tunneling technology, shield tunneling method has been paid more and more attention and favored. However, under normal circumstances, after the shield machine completes tunnel excavation and segment assembly, it is necessary to pour inverted arches at the bottom of the segment to provide preliminary conditions for laying the track bed for trains to pass through. At present, th...

AI Technical Summary

Problems solved by technology

At present, the inverted arch filling is carried out after the tunnel excavation is completed or after a certain distance, and most of them adopt the method of artificial formwork, with a low degree of mechanization

Without synchronization, if the coordination between the two is not good during the construction process, they will restrict each other and affect the construction efficiency
