Spraying and maintaining device for concrete

Abstract

The invention discloses a spraying and maintaining device for concrete, and belongs to a maintaining device. The spraying and maintaining device for concrete comprises a walking trolley, a trolley walking driving mechanism, a trolley walking rail, a spraying device and a supporting device, wherein the spraying device comprises a front spraying device, a middle spraying device and a rear spraying device which are respectively connected with a water pump through connection pipes; pipe coilers are arranged between the connection pipes and the water pump and are arranged on the walking trolley; the connection pipes are respectively connected with the water outlet ends of the pipe coilers; the water inlet ends of the pipe coilers are connected with the water pump; an electromagnetic valve is arranged on each connection pipe; the water pump, the electromagnetic valves and the trolley walking driving mechanism are respectively connected with a controller. The spraying and maintaining device for concrete has the characteristics that manual spraying operation is avoided, the labor intensity of a worker is alleviated, and the working efficiency is improved; furthermore, maintenance is carried out by water, so that the maintaining cost is reduced.

Description

technical field [0001] The invention relates to a maintenance device, in particular to a concrete spraying maintenance device after the formwork is removed in a building construction project. Background technique [0002] After the concrete is poured, if the climate is hot and the air is dry, if the maintenance is not carried out in time, the water in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will make the cement particles that have formed a gel body unable to fully hydrate and cannot be transformed into stable crystals. Lack of sufficient cohesion, resulting in flaking or powdering off the concrete surface. In addition, when the concrete does not have sufficient strength, the premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks. Therefore, the maintenance of the initial stage after concrete pouring is very important. [0003] After the surface covering or formwork is removed from the con...

AI Technical Summary

Problems solved by technology

[0004] In the current maintenance, there is maintenance by spraying curing fluid, but the cost of curing fluid is high, which increases the maintenance cost

There is also water spray maintenance through artificial back sprayer, but manual operation is required, which increases the labor intensity of workers and reduces work efficiency
