The concrete wet spraying vehicle is a type of equipment used for concrete spraying operations. It integrates spraying, hydraulic, and walking systems, supported by an engineering vehicle chassis, with strong mobility, rapid transition, and a wide spraying area that can rotate 360°. Through the pumping system, pre-mixed concrete is delivered to the spray head, while adding accelerators to spray onto the construction surface. It features high efficiency, a high degree of automation, and can spray a large volume of concrete per hour, allowing precise control of the mix ratio and accelerator dosage to ensure spraying quality. It can adapt to different shaped construction surfaces and also has advantages such as a large construction range, low rebound rate, and minimal dust, widely used in tunnels, mines, culverts, and foundation pit support projects.
