The invention discloses a water-saving spray curing device for a concrete building structure, and relates to the technical field of spray curing, comprising a
workbench, a lifting device is fixedly installed at the bottom of the
workbench, a moving device is fixedly installed at the bottom of the lifting device, and the spray curing device is arranged on the top of the
workbench, the spray curing device comprises a
water storage cylinder, a pumping device, a water tank, a spraying device, a water collecting tank, a water guide
pipe, a support frame, a motor, a reciprocating screw, a fixed plate, a trapezoidal plate, a threaded block, a sliding rod and a circular ring, the water in the
water storage cylinder is pumped out by the pumping device, and then enters the spraying device through the water tank, and the wall is sprayed by the spraying device, the
water storage cylinder is fixedly installed on the top of the workbench, the pumping device is fixedly installed on the bottom of the inner wall of the water storage cylinder, and the water tank is fixedly installed on the top of the workbench, and
water resources can be saved by collecting splashed water, and water can be prevented from flowing downwards and directly causing
water resources waste.
