Installation device for superstructure in tunnel

Abstract

The invention provides a mounting device for an upper structure in a tunnel. The mounting device comprises a bottom frame, an upper frame, a slide hoisting portion and a control portion. The bottom frame is positioned on the upper sides of brackets in the tunnel, advances along a path of a pipeline of a shield and comprises a bottom frame body, first slide units and an upright column group, the first slide units are arranged on two sides of the bottom frame body, and the upright column group is positioned on the bottom frame body and is fixedly connected with the bottom frame body; the upper frame which is positioned on the upright column group comprises an upper frame body and a frame cantilever unit, and the frame cantilever unit extends out along a back side of an advancing direction of the to-be-mounted path and is connected with the bottom frame body by a support assembly; the slide hoisting portion is positioned below a convex front beam of the frame cantilever unit; the control portion is electrically connected with the first slide units and the slide hoisting portion and drives the first slide units and the slide hoisting portion to move. The mounting device has the advantages that the mounting device is erected on the brackets and can travel on the brackets, so that the upper structure in the tunnel can be quickly mounted by the aid of the mounting device, horizontal transportation carried out in the tunnel is hardly affected when the mounting device is used, structure lifting construction can be simultaneously carried out in the tunnel, the mounting device does not occupy transportation spaces in the tunnel, and accordingly the internal tunnel structure construction efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of engineering and relates to an installation device for an inner superstructure of a tunnel. Background technique [0002] With the rapid development of urban municipal construction and rail transit, the underground space has been continuously developed and utilized, and the large-diameter shield method of single-hole and double-track is more and more used in subway tunnels, such as figure 1 As shown, the single-hole and double-track tunnel projects have the characteristics of long distance, tight construction period, and difficult construction. [0003] Compared with ordinary single-hole single-track subway tunnels, the large-diameter subway tunnels with single-hole and double-track tunnels also have internal structures such as corbels, partition walls, and flue panels during shield excavation. The structure adopts the method of synchronous construction, which causes the contradiction between horizontal t...
