Problems solved by technology

When pouring concrete for the secondary lining, it is necessary to install the concrete pouring formwork first. Since the top of the tunnel is an arched structure, in order to facilitate the support of the formwork, the support structure of the formwork will also be set in an arc shape. However, the existing f

Abstract

The invention discloses a supporting device for a secondary lining of a tunnel vault of a broken area of a high seismic zone. The supporting device comprises a template supporting structure, a fixed supporting structure and a base, wherein the template supporting structure comprises a first arc plate and two second arc plates; the two second arc plates are respectively rotatably connected to two ends of the first arc plate; the fixed supporting structure comprises a first electric hydraulic push rod, two second electric hydraulic push rods, an arc-shaped supporting plate and a vertical column;the arc-shaped supporting plate is arranged below the template supporting structure in the same arrangement way; the push end of the first electric hydraulic push rod is fixed with the first arc plate, and the fixed end of the first electric hydraulic push rod is fixed with the convex surface of the arc-shaped supporting plate; the push ends of the two second electric hydraulic push rods are respectively fixed with the corresponding second arc plates, and the fixed ends of the two second electric hydraulic push rods are fixed with the convex surface of the arc-shaped supporting plate; the topend of the vertical column is fixed at the center position of the concave surface of the arc-shaped supporting plate, and the bottom end of the vertical column is fixed at the top of the base. The supporting device disclosed by the invention can share the pressure on the tunnel vault and is high in supporting stability.

Description

technical field [0001] The invention relates to the technical field of secondary lining construction of tunnels, in particular to a support device for secondary lining of tunnel vaults in broken areas in high seismic zones. Background technique [0002] A tunnel refers to a channel dug out of an existing building or earth-rock structure. During the construction of the tunnel, it is usually necessary to perform secondary lining on the tunnel to increase the strength of the tunnel and make the tunnel more durable. [0003] The secondary lining is the molded concrete or reinforced concrete lining applied on the inner side of the primary support in the tunnel engineering construction, and forms a composite lining together with the primary support. When pouring concrete for the secondary lining, it is necessary to install the concrete pouring formwork first. Since the top of the tunnel is an arched structure, in order to facilitate the support of the formwork, the support structu...
