Abstract

The invention relates to a tunnel inner sleeper and an application construction method thereof. The tunnel inner sleeper comprises a first bolster, a second bolster and a third bolster which are sequentially and parallelly laid, one side of the second bolster is detachably connected with the first bolster, the other side of the second bolster is detachably connected with the third bolster, the topelevation of the first bolster is as same as that of the third bolster, the top elevation of the second bolster is lower than that of the first bolster, a single rail of a shield tunneling machine isarranged on the top surface of the first bolster, a rail of a storage battery car is arranged on the top surface of the second bolster, and a rail of a backup trailer is arrange don the top surface of the third bolster. The first bolster, the third bolster and the second bolster of the tunnel inner sleeper are detachably connected, so that first bolster and the third bolster can be recycled, andconstruction cost is reduced. The application construction method of the tunnel inner sleeper is simple to operate, rail flatness is high, and material transportation and running of the shield trailerare facilitated.

Description

technical field [0001] The invention relates to the field of shield construction, in particular to a sleeper in a tunnel and an application construction method thereof. Background technique [0002] The shield machine is a large-scale high-tech comprehensive construction equipment specially used for tunnel engineering. It has a movable steel structure shell (shield shell), and the shield machine is equipped with mechanical devices such as excavation, soil discharge, assembly and propulsion. A series of operations such as soil layer excavation, muck drainage, lining assembly and shield tunneling enable the construction of the tunnel structure to be completed at one time. Tunnels using the shield construction method generally use battery cars to transport a series of materials such as muck, segments, and slurry back and forth. Therefore, when using battery cars for transportation, solid sleepers and tracks are required as the foundation. In addition, the shield trolley track i...
