Viaduct concrete curing device

Abstract

A viaduct concrete curing device comprises a rack, a rotary reset part, an up-down telescopic part, a left-right telescopic part and a water spraying part, the rack is provided with a water tank and walking wheels, the walking wheels drive the rack to move along the ground, a port of one end of a water hose is located on the lower portion of the water tank, water in the water tank is pumped through a water pump, and water is conveyed to a water spraying pipe assembly part; under the pressure of the water pump, water spray nozzles spray water so as to maintain the lower surface of the viaduct concrete, and the water hose is arranged along the trend of an upper bracket and a side bracket and is bound and fastened with the upper bracket and the side bracket. The construction site limitation is overcome, and flexible construction can be achieved; according to the device, a plurality of water spray nozzles work simultaneously, the one-time water spraying area is greatly several times larger than that of common water spraying, and the maintenance progress is greatly accelerated.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to maintenance equipment for preparing concrete. Background technique [0002] In the process of concrete pavement construction, if the concrete is poured, if it is not maintained in time, the moisture 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 cohesive force, resulting in flaky or powdery shedding on the concrete surface, affecting the quality of the concrete. In addition, when the concrete does not have sufficient strength, the water evaporates prematurely, causing large shrinkage deformation and shrinkage cracks. Therefore, the concrete must be cured in the initial stage after pouring. Generally, watering is used to complete the natural curing. [0003] For the viaduct cement pav...

AI Technical Summary

Problems solved by technology

[0003] For the viaduct cement pavement, after the pouring is completed, concrete curing must also be carried out in the initial stage. The concrete lower surface of the viaduct is higher than the ground or is limited by other specific conditions of the construction site, making it inconvenient to spray water on it. In order to solve this problem, the industry urgently needs to provide a kind of concrete maintenance equipment with flexible operation and fast construction speed.
