The wet concrete spraying system for tunnel plays an important role in the tunnel construction process, providing initial support for the entire tunnel construction and ensuring the safety of subsequent tunnel construction, especially for large section super-long highways and railway tunnels. With the frequent construction of highway, railway and subway tunnels in China, tunnel [...]
Working principle of wet shotcrete machine The working process of the concrete jet machine is: the premixed mixture falls into the hopper through the screen, and is transferred from the skipper and the batching tray into the falling hopper to the rotor cup. As the rotor rotates into the pneumatic system, the [...]
Concrete shotcrete machine Shotcrete machine is the use of compressed air to transport a certain proportion of concrete mix through the pipeline and high-speed injection to the surface to be solidified by the spray surface to form a concrete support layer. In recent years, shotcrete technology has been widely used in construction, [...]
The wet shotcrete machine is an anchor spray support machine with better comprehensive performance such as reducing dust, reducing rebound and saving materials at home and abroad. Currently widely used in mines, culverts, building foundation pit support, river slope protection and other projects. Wet shotcrete gunite machine features: Wet spray machine [...]
Whether the selection of concrete spraying machine is reasonable or not directly affects the construction progress and project quality. Therefore, the type and quantity of the shotcrete machine should be correctly selected according to the size of the project, the length of the construction period, and the specific conditions of the construction. [...]
The concrete spraying machine has the advantages of high mechanization, simple process and high production efficiency. It is widely used in underground and ground concrete projects in construction, municipal, railway, mining and other industries. It has been widely used in many countries and has shown good technical and economic benefits. According [...]
Metode Shotcrete: Before starting, first connect the ventilation, water and electricity, open the intake valve to reach the rated pressure gradually, and then start the motor no-load operation to confirm that everything is normal before the operation can be started; the station is strictly prohibited in front of the nozzle, the operator should always [...]
