Problems solved by technology

[0004] The object of the present invention is to provide a ballastless track structure in a railway tunnel and a deviation correction method thereof, so as to solve the problem that when correcting the deviation of the existing ballastless track structure in a railway tunnel proposed in the above-mentioned background technology, the empty position cannot be located in time, causing the train to pass by. When there is a serious void, dynamic deformation will occur, and the conventional grouting method is heavy and heavy, and the on-site construction is inconvenient. At the same time, due to the process of operating the line, the efficiency of operating the line through manual inspection is not only low, but it is easy to cause aggravated damage, expand the scope of deviation correction, and increase Disturbances to track and subgrade structures

Abstract

A disclosed ballastless track structure in a railway tunnel comprises lifting tools, a base plate and a track plate, the lifting tools are installed at the two sides of the base plate through anchor bolts, a first cushion plate is arranged in the outer sides of the lifting tools in a contact mode, a jack is installed at the top of the first cushion plate, and a pull rope displacement sensor is installed at one side of the top of the first base plate. Compared with the prior art, the reinforcing effect of the track plate can be detected through comparison testing of a base point vibration sensor and a measuring point vibration sensor, the stability condition of the track plate can be conveniently found in time, the function of positioning and monitoring the base plate is achieved, dynamic response when a train passes is improved, displacement of the lifting tool can be monitored in real time through the pull rope displacement sensor, when displacement of the lifting tools is monitored, a pull rope displacement sensor transmits an electric signal to a monitoring device through the wire, so that a worker can find sinking and cracking of the base plate in time, the timeliness of sinking and cracking of the base plate is improved, and the overall damage degree of a circuit is reduced.

Description

technical field [0001] The invention relates to the technical field of railway tracks, in particular to a ballastless track structure in a railway tunnel and a deviation correction method thereof. Background technique [0002] In recent years, China's high-speed railway construction has developed rapidly and has been put into operation one after another. The operating environment of high-speed railways is complex, and the differences in construction methods, base structures, usage conditions, load conditions, and climatic conditions lead to complex usage conditions of subgrade structures, with varying degrees of failure. Diseases, roadbed diseases cause cracks and uneven settlement on the track slab and support layer of the high-speed railway ballastless track line, and the high-speed railway skylight time is short, which in turn increases the difficulty and workload of line maintenance and maintenance. The ballastless track in the high-speed railway tunnel The base structur...
