[0002] Concrete is a general term for engineering composite materials that are bonded together by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion and mixed to obtain cement concrete, also known as ordinary concrete. It is widely used in civil engineering. Concrete pavement is prone to cracking after pouring, and the concrete pavement needs to be fixed and sprayed with water.

With the help of the mutual engagement of the rack 11 and the gear 8, the first electric push rod 9 can pull the gear 8 to rotate back and forth. The gear 8 is fixedly sleeved on the outside of the water delivery pipe 5, so it can drive the water delivery pipe 5 to rotate, so that the water spraying range of the nozzle on the water delivery pipe 5 is expanded during the back and forth swinging process, which can better adapt to the concrete body clamped by the clamping assembly.
