Automatic spraying curing device for concrete bridge pier and use method

Abstract

An automatic spraying curing device for a concrete bridge pier comprises a lifting system, a water supply system and a spraying system. The lifting system and the water supply system are started according to the set time. While a spraying curing frame is lifted, water pumped by a water pump is sequentially conveyed into a main water conveying pipe, a branch water conveying pipe and a spraying water pipe. Water spraying curing is carried out on the surface of the concrete bridge pier needing curing through water sprayed by sprayers. A winch is automatically reversed after the spraying curing frame is lifted to the top of the bridge pier, and the spraying curing frame descends to a bearing platform surface in continuous spraying. The automatic spraying curing device for the concrete bridge pier is simple in structure, reasonable in design, and convenient to use and operate. The problem that manual water spraying curing can not meet the spraying requirement, thereby causing cracks of the bridge per can be effectively solved, the engineering quality is improved, and the service life of the bridge pier is prolonged. A water curtain formed by sprayed water covering a pier body concrete curing surface is uniform, the omni-directional and full-wetting curing quality standards can be met, the curing effect is quite remarkable, and high pier high-altitude concrete curing is realized.

Description

technical field [0001] The invention relates to a concrete maintenance device and a use method, in particular to an automatic spray maintenance device for concrete bridge piers and a use method, belonging to the field of road and bridge construction. Background technique [0002] Poured concrete needs to be cured after solidification to keep the surface of the concrete moist, so as to ensure that the hydration and hardening of the cement can proceed smoothly. 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 structural strength, safety and normal use. At present, the maintenance method of bridge pier concrete structure generally adopts artificial water spraying maintenance, but with the expansion of road and bridge construction scale, th...

AI Technical Summary

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 structural strength, safety and normal use.

At present, the maintenance method of bridge pier concrete structure generally adopts artificial water spraying maintenance, but with the expansion of road and bridge construction scale, the artificial water spraying maintenance method can no longer meet the demand, and it is easy to miss the maintenance phenomenon, which will cause cracks in the pier body. Potential safety hazards affect the quality of the project and reduce the service life of the bridge pier. At the same time, the labor intensity of the workers is high, the safety risk is high, and the work efficiency is low. An ideal automatic spraying maintenance device for concrete pier and its use method have not yet been disclosed.
