Problems solved by technology

[0003] Concrete maintenance in traditional double-block ballastless track construction is mostly covered with geotextiles or plastic films to cover the curing soil and then manually sprinkled for curing. The quality of curing is uneven, which may easily cause poor curing effect and curing cracks.
Moreover, the maintenance workers are labor-intensive and use a lot of labor

specific Embodiment

[0034] The specific steps for the construction of the maintenance equipment 11 for the double-block ballastless track 1 bed slab are:

[0035] S11: Laying of geotextiles and construction stakeout. Specifically, the following steps are included:

[0036]Before the construction of the track bed slab, reasonable tooling and equipment shall be provided according to the construction organization, and the equipment and equipment such as rail bent frame, steel formwork gantry crane, truck crane, water truck, pump truck, sleeper-dividing platform, rainproof shed and fine-tuning instrument are complete. When the track bent frame is equipped, it should be reasonably equipped according to the design form of the track bed slab, and special attention should be paid to the design size of the track bed slab with special structures such as continuous beams and abutments.

[0037] S12: Bottom reinforcement installation: use insulating coated reinforcement, place longitudinal reinforcement fir...

Abstract

The invention discloses maintenance equipment for a double-block ballastless track bed slab. The maintenance equipment comprises a position sensor arranged on a track, a temperature and humidity sensor arranged on a poured bed slab, and an intelligent maintenance vehicle which is used for travelling on the track ground, wherein the intelligent maintenance vehicle comprises a vehicle body, a control system, a spraying system and a maintenance shed, the intelligent maintenance vehicle travels according to a path set by the position sensor, the control system is used for receiving data transmitted by the temperature and humidity sensor and the position sensor so as to control the spraying system to spray and maintain concrete poured on the bed slab, and the maintenance shed is arranged on the spraying system in a covering mode. The maintenance equipment for the double-block ballastless track bed slab is good in maintenance effect and high in automation degree.

Description

technical field [0001] The invention relates to the field of track construction equipment. More specifically, the present invention relates to a maintenance device for double-block ballastless track bed slabs. Background technique [0002] The double-block ballastless track is mainly composed of the lower support system (base), cast-in-place concrete track bed slab, double-block sleepers, highly elastic fasteners, and steel rails. Compared with other types of ballastless track, double-block ballastless track has the advantages of relatively low cost, relatively single technical standard, and easy construction technology. Therefore, it has been applied in many high-speed railways in my country. [0003] Concrete maintenance in traditional double-block ballastless track construction is mostly covered with geotextiles or plastic films to cover the curing soil and then manually sprinkled for curing. And the labor intensity of maintenance workers is high, and the use of labor f...
