Shotcrete machine in small tunnel

2020-04-03 15:34:10

Shotcrete machine in small tunnel, we usually recommend using a wet shotcrete machine. Shotcrete machine is divided into wet shotcrete machine and dry shotcrete machine. First of all, let's understand the difference.
Dry spraying refers to adding a dry mixture to a dry nozzle, adding water to the nozzle, spraying concrete with a hand-held nozzle, and manually installing a large number of accelerators. This dry spray technology has a high rebound rate, the rebound concrete cannot be reused, and the waste is serious. The spray volume per hour is only about a few cubes, and the efficiency is low; the dust is large, the construction environment is bad, the probability of accidents for construction workers is high, and workers It is too close to the injection site, and once it collapses, it is difficult to escape.
Wet sprayer adopts imported wireless remote control, with friendly man-machine interface and strong maneuverability. The system has the advantages of fast running speed, strong anti-interference ability, real-time fault monitoring and abnormal display.

Wet shotcrete machines have been widely used in the construction of small tunnels. This new type of injection molding machine uses engineering vehicles or chassis, which has strong mobility and convenient turning. High spraying accuracy, small spray dead zone, four-wheel drive, compact structure, suitable for the limited construction site.

Gaodetec wet mix shotcrete machine is currently an anchor spraying supporting machine with better comprehensive performances such as reducing dust, reducing rebound and saving materials. Currently it is widely used in mines, culverts, building foundation pit support, river slope protection and other projects. Gaodetec has developed a number of different power-driven wet spray machines, and our GSZ3000 series shotcrete machine with dosing pump. 

GSZ3000 series wet-mix shotcrete machine is used for wet spraying concrete. Its advantages are easy sealing, smooth stream and uniform spraying etc. It also has some obvious advantages such as advanced technology, perfect structure, stable performance, convenient operation and longevity of service etc. In order to make the wet shotcrete machine move more conveniently in the application, we install a solid wheel on the bottom of the shotcrete machine.
