Steel spring floating slab monolithic track bed construction method based on track engineering

Abstract

The invention discloses a steel spring floating slab monolithic track bed construction method based on track engineering, which comprises the following steps: S1, installing a walking rail in a tunnel, and pouring a support base body at the bottom of the tunnel; s2, manufacturing a floating slab reinforcement cage , arranging vibration isolator assemblies on the reinforcement cage at intervals, and fixing steel rails to the top of the reinforcement cage; s3, laying an isolation layer on the supporting base body, placing the floating slab reinforcement cage on the isolation layer and calibrated, and then conducting concrete pouring to form a ballast bed; and s4, after the ballast bed reaches the designed strength, lifting the ballast bed to the designed height through a vibration isolator assembly. According to the technical scheme, the beneficial effects are as follows: the reinforcement cage is manufactured in a prefabricated mode, ground operation with a larger operation space can beselected, large-batch manufacturing can be conducted at the same time, the operation efficiency can be improved, jacking can be conducted after ballast bed pouring is completed, a ballast bed has certain elasticity, impact force generated by vehicles can be absorbed in the operation process, and the service life of a rail is prolonged.

Description

technical field [0001] The invention relates to the technical field of track engineering, in particular to a construction method for a steel spring floating slab integral ballast bed based on track engineering. Background technique [0002] The track bed is an important part of the track and the foundation of the track frame, so the overall quality of the track bed will affect the quality of the track; the existing track bed is divided into ordinary ballast bed, asphalt track bed and concrete integral track bed, and the integrity of the concrete integral track bed Well, the cleanliness is high, but it is difficult to guarantee the elasticity of the track. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a construction method of steel spring floating slab integral ballast bed based on track engineering, which has high construction efficiency and good elasticity. [0004] A kind of steel spring floating slab integral ...
