The equipment is suitable for large (highway, railway) tunnels, hydropower stations, underground engineering, slope protection and other shotcrete construction environment in the spray machine, it is to improve work efficiency, reduce the labor intensity of workers, improve material utilization, based on the engineering practice and the development of shotcrete machine is a set of automatic shotcrete, automatic shotcrete, automatic shotcrete, automatic shotcrete, automatic shotcrete, quick coagulant and other types of integrated equipment, is more representative of the domestic comprehensive large-scale equipment.

This system solves the shortcomings of manual feeding in the traditional shotcrete operation, makes the feeding and shotcrete complete by machinery, and eliminates the harm of dust generated by manual mixing and feeding to workers' bodies in the previous shotcrete process. The rebound rate is low and the shotcrete surface is of good quality. It is a general-purpose mechanical automatic feeding for shotcrete and anchor support in tunnel construction, which greatly improves the tunneling speed and work efficiency, it is a general-purpose mechanical automatic feeder for shotcrete and anchor support in tunnel construction.

The quality of the cable of the foundation pit support shotcrete machine must meet the relevant standards, that is, the good sealing performance of the cable interface, whether the tensile strength meets the standard, and whether the protection of the explosion-proof surface is qualified are also the main factors affecting the efficiency of the shotcrete machine. For example, when the electric control system of the shotcrete machine equipment needs to be connected or repaired, the changes of each pressure gauge should be observed at any time. When the air pressure is abnormally high, stop feeding in time, and then carry out normal work after the pressure returns to normal. Here, the operator is required to have the requirements of "fast" and "accurate", that is, the operator should deal with the problem in time. Quasi means that when the operator handles the problem, he must be accurate and correct. If bolts and nuts are loose when the shotcrete machine works for a long time.

Generally speaking, the machine should be cleaned after each shift, which does not exceed 80 ℃ after use. The surface of the rotor sealing plate and lining plate should be cleaned. At the same time, the wear of the sealing plate and the rotor lining plate should be checked. If the sealing plate is worn to a certain extent, the sealing plate must be ground.

The foundation pit support shotcrete machine improves the air return structure of the original shotcrete machine and reduces the air return dust. This product is controlled by an automatic system. The operation switch buttons are integrated on the panel. It is easy to understand and can be operated skillfully without professional training. Self-provided power wheeled walking, high speed is 5KM per hour, low speed operation is 5KM per hour, low speed construction can use single plate type operation switch, can be easily operated, without professional training can be skilled operation of this product, using self-powered wheeled walking, high speed is 5KM per hour, low speed operation can be based on the actual situation of the work surface to decide, which method to use to solve the problem. On the contrary, new energy with abundant reserves, especially photovoltaic, wind power, nuclear power and energy generation, will be the main direction of future development. At the same time, energy is easy to cause. It is necessary to further unify the new development concept and action into the new development concept, closely focus on accelerating green development, and properly handle the relationship between development and protection.
