Shotcrete is a fast and effective reinforcement method that has evolved from roadway support technology to the reinforcement of above-ground structures. It has its own unique advantages: Shotcrete uses a shotcrete machine and compressed air as power to transport a certain proportion of the mixture through a high-pressure pipeline and spray it onto the sprayed surface at a high speed.

The spraying speed of concrete from the nozzle can reach 60m~80m/s. It depends on the repeated and continuous impact of cement and aggregate during high-speed spraying to compact the concrete. Due to the small water-cement ratio (0.4-0.5), it has high bonding strength with concrete, masonry, and steel. It can be used in combination with steel mesh to transfer tensile stress and shear stress on the bonding surface. Higher mechanical properties and good durability can greatly improve the bearing capacity of the masonry and strengthen the integrity. At the same time, the mortar can enter the reinforced pores and cracks under the high-speed concrete spraying state, so that the original structure can be restored to a certain extent.

It is suitable for masonry wall cracking reinforcement, brick and concrete structure layer wall reinforcement, seismic reinforcement, accident treatment and other projects.

Applicable conditions of shotcrete slope protection:
1. For rock slopes that are hard and easy to weather, but have not been severely weathered, in order to prevent further weathering, spalling and sporadic chipping, shotcrete machine is used to spray concrete to form a protective layer on the slope.

2. It can be used on high and steep slopes, especially for slopes where the upper rock layer is broken and the lower rock layer is intact, and slopes that require large-area protection and are more concentrated. It is more economical to use shotcrete or shotcrete protection.

3.It is not suitable for claystone slopes with poor diagenesis.

4.It is suitable for dry slopes where groundwater is not developed.

Gengli is a professional manufacturer of shotcrete machine products. The products include dry shotcrete machine, wet shotcrete machine, Truck-mounted Shotcrete Machine and Truck-mounted Robot Shotcrete Machine. The Gengli machinery more than 26 years has specialized in production of shotcrete equipment.
