(2)technical background
Wet type concrete sprayer is construction equipment which is widely used in fields such as underground engineering, geotechnical engineering and municipal engineering. Due to various reasons in the past, dry type spraying machine is main spraying equipment. However, more and more wet type concrete sprayers are put into market because of people¡¯s increasing environmental awareness and great requirements on quality of gunite concrete. At present, it is demanded to use wet type concrete sprayer in design of railway tunnel and underground engineering construction.
The wet type concrete sprayer meets users demands on concrete spraying supporting work in tunnel construction process and realizes intelligent control of shotcreting homework

Hzsp30 wet type concrete sprayer is made up of chassis system, work device system, hydraulic system, electrical system and cab
