Expressway tunnel groove integral lining trolley

Abstract

The invention relates to tunnel construction machinery, and discloses an expressway tunnel groove integral lining trolley, which comprises a top mold assembly, a side mold assembly, a hydraulic system, a walking system and an electric system, wherein the walking system is driven by the hydraulic system to move on a steel rail, and the top mold assembly is erected on a gantry table beam through a top mold upright post frame and is driven by a jacking oil cylinder arranged on a gantry cross beam; the gantry table beam is arranged on the gantry cross beam through a middle jack frame, a plurality of side mold lead screws and reinforced lead screws are hinged between the side mold assembly and the gantry upright posts arranged at the two ends of the gantry cross beam; the lower side of the side mold assembly is hinged to side mold support feet, and a groove bottom plate and a filling mold used for integrally forming the tunnel bottom surface are arranged under a pad plate. The invention aims at providing the expressway tunnel groove integral lining trolley with the advantages that the integral construction between the tunnel wall and the tunnel bottom surface is realized, the construction period is shortened, the material and labor waste is avoided, in addition, the structural performance is stable, and the integral performance is good.

Description

technical field [0001] The invention relates to a tunnel construction machine, in particular to an integral lining trolley for expressway tunnel grooves. Background technique [0002] With the development of the economy, there are more and more highway constructions, which have brought great convenience to people's life and production; in these constructions, there are more tunnels that need to be excavated or built, and there is a kind of construction in tunnel construction The method is called lining. Lining refers to a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body in order to prevent the deformation or collapse of the surrounding rock. Lining technology is usually used in tunnel engineering and water conservancy channels. Simply speaking, lining is lining tunnels and rock caves. One way is to use block lining, and the other way is to use prestressed high-pressure grouting concrete lining. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] For expressway tunnel lining construction, in the current construction plan, it is often used to use the lining trolley to line the tunnel wall first, and then carry out the construction of the sewer and wire trough at the bottom of the tunnel after the construction is completed. The construction period is shortened, and the secondary construction will cause waste of materials and labor, and the integrity is poor; and the structure of the existing lining trolley is not stable enough, and it is prone to failure during use
