Wet spraying machine is used for wet shotcrete equipment, compared with dry and wet spraying machine,have the advantage of little working dust, small rebound spray , protect the environment, save raw materials and improve the quality of shotcrete and other significant advantages, operation and maintenance convenient.Using the working principle of low voltage low speed vortex conveying,close to jet,which overcome the plugging pulse, segregation problems. Made the injection material flow uniform and stable to improve spray layer material.
Using wet spraying machine make shotcrete operations, can greatly reduce the dust concentration and spring rate, increase the thickness of a spray, improve production efficiency, and ensure project quality.
①sealing structure is good, reduce dust pollution and small dust .
②small rebound and saving material.
③as the concrete mixed well prior to grouting, so ensure the ratio of concrete and the quality.
①high price of piston wet spraying machine;
②the transport of wet concrete is too much trouble, and sometimes need concrete tank and other equipment;
③after each injection operation must cleaned with water.
