Embodiment Construction

[0034] The invention discloses a construction method of an integral ballast bed, which uses a short sleeper integral ballast bed, and adopts the construction method of "rail-bent-rail method". Among them, the short sleepers are manufactured by the factory, and the main construction method is: transport the short sleepers and 25m non-porous rails to the track laying construction site by car, and use the under-mounted rail support frame to set up the vertical rail row, and at the same time carry out rough track adjustment and reinforcement. For the construction of binding, formwork and other processes, after the construction of each process meets the requirements of the design technical specifications, the concrete of the track bed will be poured, see the attached figure 1 Shown is the detailed method.

[0035] The general method is as follows:

[0036] Step (1) Assembling the rail row

[0037] At the construction site, 100mm thick square wood is used as the rail assembly plat...

Abstract

The invention discloses a construction method of a virescence-section monolithic track-bed for tramcars. The construction method is based on track panel erection; short railroad ties are provided by manufacturing plants; mainly, the short railroad ties and 25-meter imperforate steel rails are transported to a rail laying construction site through automobiles; a through supported steel rail bracket is utilized for track panel erection; meanwhile, such working procedures as track coarse tuning, steel bar binding and template mounting are constructed; after all the working procedures are constructed according to the design and technical specification requirements, concrete is poured into the monolithic track-bed, and then virescence construction is performed. The construction method has the advantages that through the reasonable layout of a track-bed structure, the construction process is reasonably designed, the construction quality and speed are high, the construction progress is accelerated and the production cost is reduced; meanwhile, the purposes of air purification, pollution prevention and treatment, climate regulation and environment virescence are fulfilled.

Description

technical field [0001] The invention relates to a construction method for an integral track bed, in particular to a construction method for greening an integral track bed for trams. Background technique [0002] The track bed is an important part of the track and the foundation of the track frame. The track bed usually refers to the ballast (ballast) cushion layer laid on the subgrade surface under the railway sleeper. The main function is to support the sleeper, transmit the huge pressure on the upper part of the sleeper to the roadbed surface evenly, and fix the position of the sleeper, prevent the sleeper from moving longitudinally or laterally, greatly reduce the deformation of the roadbed, and at the same time ease the impact of the locomotive wheel pair on the rail. Allows for easy drainage. The track bed is divided into ordinary ballast track bed, asphalt track bed and reinforced concrete integral track bed. During the on-site construction process, there are many i...
