Spraying device with high-speed rail bridge pier automatic maintenance function

Abstract

The invention relates to a spraying device with the function of automatic maintenance of high-speed railway pier, which is used for spraying high-speed railway pier; its hoist is installed on the top of the high-speed railway pier; one end of the steel wire rope is wound on the hoist, the other end is connected to the reinforced steel pipe, and can The reinforced steel pipe is raised and lowered; the steel wire rope is supported by the roller; the water supply pipe is horizontally installed on the reinforced steel pipe; the spray nozzles are evenly distributed on the water supply pipe; the spray guide device is also installed on the reinforced steel pipe, which abuts on the high-speed railway bridge pier; One end of the water pipe is connected to the water supply pipe, and the other end is connected to the water pump; the water ditch is arranged at the bottom of the high-speed railway pier, and is connected to the water tank; the water pump is located in the water tank. The invention is light and simple in structure, reasonable in design, easy to install, and the equipment is automatically operated during use without any manual assistance; the equipment can be used repeatedly; the construction water can be recycled to save water; it is suitable for the maintenance of high-speed railway bridge pier concrete, piers Good body care.

Description

technical field [0001] The invention relates to a spraying device, in particular to a spraying device with the function of automatic maintenance of high-speed rail pier, and belongs to the technical field of high-speed rail supporting equipment. Background technique [0002] The cast-in-place high-speed railway piers need to be cured after the final setting of the cement to keep the concrete surface moist, so as to ensure the smooth progress of the hydration and hardening of the cement. If the maintenance is not carried out in time, when the concrete surface loses water, the hydration reaction of the cement will stop, and the surface will dry and shrink at the same time. Under the action of shrinkage stress, the concrete structure will produce cracks, which will affect the safety and normal use of the structure. [0003] At present, the maintenance method of high-speed railway bridge piers is generally to use artificial water spraying maintenance. With the expansion of produ...

Problems solved by technology

If the maintenance is not carried out in time, when the concrete surface loses water, the hydration reaction of the cement will stop, and the surface will dry and shrink at the same time. Under the action of shrinkage stress, the concrete structure will produce cracks, which will affect the safety and normal use of the structure.

[0003] At present, the maintenance method of high-speed railway bridge piers is generally to use artificial water spraying maintenance. With the expansion of production scale, manual pouring can no longer meet the demand, and there will inevitably be leakage of maintenance, which will cause cracks in the pier body and cause safety hazards , which affects the quality of the project and reduces the service life of the pier. At the same time, the labor intensity of the workers is high, the safety risk is large, and the operation efficiency is low.
