Servo rail suitable for railway tunnel across skip fault and control method thereof

Abstract

The invention relates to a servo rail suitable for a railway tunnel across a skip fault and a control method thereof. The servo rail comprises a flexible isolation layer, a sticky energy consumption layer and a servo regulation layer which are sequentially arranged from bottom to top, wherein the flexible isolation layer comprises an arch-inhibiting filler and elastic baffle blocks at the two sides; the sticky energy consumption layer is a polyurethane solidifying channel bed; the flexible regulation layer comprises a rigid structure and a control unit; the rigid structure comprises a longitudinal beam connected to the polyurethane solidifying channel bed; a wide ram plate is arranged on the longitudinal beam; a steel rail is arranged on the wide ram plate; the control unit comprises a monitoring module for acquiring horizontal dislocation and differential settlement of the wide ram plate, a performing module for driving the wide ram plate to move and a control module for controlling awork state of the performing module. Compared with the prior art, the servo rail has the advantages of being able to ensure integral deformation of a rail structure within a millimeter scale during dislocation of the skip fault, guarantees safe operation of railway, makes rail damage locally, and is beneficial for quick low-cost repair.

Description

Technical field [0001] The invention relates to the technical field of railway tunnel rail transit, in particular to a servo track suitable for railway tunnels crossing active faults and a control method thereof. technical background [0002] In the geographical area where fault zones are widely distributed, because of the high frequency, strong intensity and shallow source of earthquakes in this area, it is inevitable that tunnels will cross active fault areas when they are built, such as Muzhailing tunnel on Lanzhou-Chongqing line and Zheduoshan tunnel on Sichuan-Tibet line. When the active fault is dislocated, it will cause serious hazards such as peeling and collapse of the tunnel and distortion of the track structure, which will have an important impact on the safety of railway transportation. Therefore, it is particularly important to take corresponding measures to deal with the dislocation of active faults. [0003] At present, tunnel engineering mainly adopts measures suc...
