Paving equipment for ballastless track roadbed support layer of high-speed railway roadbed

Abstract

The invention discloses a spreading equipment for ballastless track roadbed support layer of high-speed railway roadbed, comprising a machine frame, wherein a lower end of the machine frame is provided with a traveling part, a plurality of groups of traveling wheels are arranged in the traveling part, and a plurality of groups of the traveling wheels are arranged on both sides of the machine frame; the ballastless track roadbed support layer of the ballastless track roadbed support layer of the high-speed railway roadbed support layer is arranged on the lower end of the machine frame. At thatfront end of the frame, a cloth part is arrange, and the cloth part is provided with a spiral roll cage which is rolling connected with the frame; At least one group of vibrate bars is arrange in thatvibrating part; A leveling part is arrange behind that vibrating part, The invention integrates the cloth, vibration and leveling equipment, so that the whole paver is simple and compact, and the left and right dimensions of the paver are greatly reduced by arranging the traveling mechanism on the upper end of the supporting template, so that the paver can be adapted to various narrow sections ofthe road and the universal performance of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment for ballastless track of railway subgrade, in particular to a paving equipment for the supporting layer of ballastless track subgrade of high-speed railway subgrade. Background technique [0002] The paver is the main mechanical equipment for road paving. It spreads the mixed material evenly on the built roadbed according to the shape and thickness of the road surface, and can perform preliminary compaction and Leveling to form a structural layer that meets certain width, thickness, flatness and compactness requirements. [0003] In the construction process of railway ballastless track, in order to realize the transition function of high-speed railway subgrade support structure from flexibility to rigidity, the material of high-speed railway subgrade ballastless track support layer has undergone a transformation from C15 low plasticity concrete to hydraulic mixture. The hydraulic m...

Problems solved by technology

[0003] In the construction process of railway ballastless track, in order to realize the transition function of high-speed railway subgrade support structure from flexibility to rigidity, the material of high-speed railway subgrade ballastless track support layer has undergone a transformation from C15 low plasticity concrete to hydraulic mixture. The hydraulic mixture is a new type of material, so it is difficult to control its performance and construction quality in the process of paving with existing paving equipment.

[0004] Moreover, when the subgrade section is short and the distance between the arrival and departure line and the platform wall is small, the currently used paving equipment cannot carry out effective paving construction work in a small space due to its large volume. Therefore, a new type of paving equipment is required. Paving equipment for the paving of hydraulic mixtures for the support course
