Assembled tunnel reinforced structure

Abstract

The invention provides a spliced type tunnel reinforcement structure. The spliced type tunnel reinforcement structure comprises a plurality of connecting rods, measurement rods, shape memory alloy rods, damping rods and a plurality of connecting joints fixed to the inner walls of tunnel segments. The adjacent connecting joints are connected through one type of the connecting rods, the measurement rods, the shape memory alloy rods and the damping rods. All the connecting joints as well as all the connecting rods, the measurement rods, the shape memory alloy rods and the damping rods form the net-shaped reinforcement structure extending along the inner wall of a tunnel inside the tunnel. The spliced type tunnel reinforcement structure can be used for reinforcing a newly built tunnel or an existing tunnel. Compared with the prior art, the spliced type tunnel reinforcement structure is convenient and fast to construct, pre-treatment on a bricking surface is not needed, the main stress form is axial stress, the force transmission route is definite, the reinforcement effect can be dynamically known and adjusted, the strength potential of connecting rod components can be given into fully play, and therefore a good strengthening and reinforcement effect is achieved.

Description

technical field [0001] The invention relates to a tunnel reinforcement structure, in particular to an assembled tunnel reinforcement structure. Background technique [0002] With the increase of the operating life of urban subway tunnels, tunnel diseases are gradually increasing. In daily monitoring, there are mainly three kinds of diseases: water leakage, cracking damage and longitudinal and lateral deformation. The above three diseases exist at the same time, and their mutual influence will eventually lead to large deformation or even instability and damage of the tunnel structure, which greatly affects the safe operation and operation of the tunnel. structural reliability. [0003] At present, in view of the large deformation problem in the tunnel, the post-reinforcement of the segment structure is carried out in the way of pasting fiber sheets and inner tension steel rings (divided into half-ring reinforcement and full-ring reinforcement methods) in the project. Among ...
