Description of 7m³*2 Automatic loading and spraying shotcrete truck:
Every tunnel is a one-of-a-kind construction that fulfills the needs of its particular surroundings, but they all share a common element: the need for structural support during the different stages of construction.
Concrete and mortar are used throughout: from pre-excavation ground treatment such as terrain stabilization with micropiles to shotcrete as primary and secondary lining, as well as cement bolts, slab lining, formwork, and formwork filling.
The type of tunnel, characteristics of the terrain, and construction method will all play a part in determining the support and lining requirements. Broadly, all the different steps follow a basic sequence that we will look into now. Refer to the image below to follow the sequence in question.

The Automatic loading and spraying shotcrete truck is suitable for concrete spraying construction operations, and it has an automatic loading shotcrete truck. This product is a new generation of shotcrete equipment derived from the traditional shotcrete machine. The equipment has the functions of automatic feeding, automatic filling of the accelerator, and automatic walking in the collection bin. On the one hand, it reduces the number of construction personnel and works intensity, on the other hand, it effectively reduces material loss and greatly improves the economic benefits of shotcreting operations.

Compared with the traditional shotcrete production method, there are many people involved, low efficiency, serious waste, machine handling, and equal defects in the feeding site. Our automatic feeding shotcrete truck has advanced technology, reasonable structure, simple operation and stable performance, Durable and other advantages. The use of this equipment from the preparation before the shotcrete to the implementation of the shotcrete has fewer process connections, high construction efficiency, short preparation time, reduced feeding workers, simple operation, and greatly improved work efficiency. Its automatic feeding function reduces the labor intensity of workers while avoiding the waste of mixed materials. This equipment is suitable for large-scale (road, railway) tunnels, hydropower stations, underground projects, slope protection, and other large-scale sprayed concrete work environments.
