Steel reinforcement cage track skeleton method construction process of steel spring floating plate track

Abstract

The invention discloses a steel reinforcement cage track skeleton method construction process of steel spring floating plate track, which comprises the following steps of: 1. preparing construction; 2. pouring and constructing a floating plate foundation and simultaneously assembling a floating plate steel reinforcement cage track skeleton; 3. sequentially hoisting the assembled floating plate steel reinforcement cage track skeleton to the constructed floating plate foundation by sections and positioning and trimming; 4. carrying out erection, track geometric dimension adjustment and pouring construction on the hoisted floating plate steel reinforcement cage track skeleton and carrying out floating plate foundation pouring and floating plate steel reinforcement cage track skeleton assembly so as to ensure that three processes of the floating plate foundation pouring construction, the floating plate steel reinforcement cage track skeleton section assembly and concrete track bed plate pouring construction are simultaneously and continuously carried out respectively; and 5. carrying out reinforced concrete track bed plate lifting construction. The invention has reasonable design, simple construction step, time and manpower saving and high construction efficiency and can effectively solve the practical problems of high construction difficulty and high technical requirement, complicated construction procedures and low construction speed of the floating plate track.

Description

technical field [0001] The invention belongs to the technical field of floating slab track construction, and in particular relates to a steel spring floating slab track reinforcement cage rail arrangement method construction technology. Background technique [0002] At present, the rapid development of urban rail transit in China has not only solved the problem of traffic congestion in densely populated urban areas, but also caused vibrations to the surrounding environment of the rail. During train operation, vibration and noise pollution to the surrounding environment are mainly due to the vibration of different frequencies of structures in the wheel-rail system. The floating slab track is a new type of track structure, which uses isolation and vibration reduction measures to isolate the ballast bed slab of the track structure from the structural foundation with an elastic body, and uses a concrete ballast bed slab with a certain quality and rigidity to carry out inertia on...
