Dry mix shotcrete equipment for the tunnel hillside project
2025-05-23 10:40:07
According to the different shotcrete construction processes, shotcrete equipment are mainly divided into two categories: dry mix shotcrete equipment (abbreviated as dry spraying machines) and wet mix shotcrete equipment (abbreviated as wet spraying machines). Dry-mix shotcrete equipment is usually used in tunnel and hillside projects to provide immediate support to prevent rock falls and soil erosion.

The dry mix shotcrete equipment uses four-wheel solid tires and is easy to move. It is mainly composed of a frame and walking mechanism, a hydraulic system, a pumping system, an accelerator system, a lubrication system, an electrical system, and a conveying pipeline. This pneumatic motor dry shotcrete machine has high construction efficiency, a spraying volume of 5 cubic meters per hour, adjustable spraying volume and accelerator addition, and easy operation and maintenance.
It is widely used in tunnel hillside projects. It is crucial to choose the right dry-mixed shotcrete (shotcrete) equipment. Here are some key components and considerations:
1. Shotcrete machine: This is the core part of the shotcrete system, responsible for mixing the dry mix with water at the nozzle and spraying it onto the working surface at high speed. When choosing, consider parameters such as its production capacity, conveying distance and height.
2. Air compressor: Provides the necessary airflow for the shotcrete machine to ensure that the material can be effectively transported to the spray gun and sprayed out. The air compressor of appropriate power needs to be selected according to the requirements of the shotcrete machine.
3. Batching and mixing system: Although dry-mixed shotcrete is pre-mixed dry material, some specific additives may need to be added or the proportion may need to be adjusted at the construction site. An accurate and efficient batching and mixing system can help ensure the quality of shotcrete.
4. Transportation equipment: Special equipment is also required to transport the dry mix from the mixing site to the spraying point, especially for places with complex environments such as tunnel construction.
5. Spraying pipes and nozzles: High-quality spraying pipes can reduce the loss of materials during transportation and ensure smooth arrival at the nozzle. The design of the nozzle directly affects the spraying effect and work efficiency.
6. Safety equipment: Since the working environment may be dangerous, it is very important to equip workers with appropriate safety equipment such as dust masks, protective glasses and hearing protection devices to protect workers' health.
Shotcrete support is a widely used support method in modern construction. It is widely used in railway and highway tunnels, mine tunnels, water conservancy and hydropower tunnels and culverts, urban subways, building foundation pits, road slopes and various underground projects.
