Wet concrete spraying trolleys are increasingly used in modern construction, especially in spraying concrete support operations in railway tunnels, highway tunnels, water conservancy culverts, mine tunnels, dam slopes, building foundation pits and military engineering. In the initial support operations of long and large tunnels, the advantages of wet concrete spraying trolleys are particularly prominent, which has strongly promoted the application of mechanized construction in tunnels.
Application fields of wet concrete spraying trolleys
1. Railway tunnels: In railway tunnel construction, wet spraying trolleys can quickly complete initial support and improve the safety and efficiency of tunnel construction.
2. Highway tunnels: Highway tunnel projects have high requirements for construction speed and quality. The application of wet spraying trolleys meets these requirements and ensures the progress of the project.
3. Water conservancy culverts: In water conservancy projects, wet spraying trolleys can efficiently spray concrete to ensure the stability and durability of culverts.
4. Mine tunnels: The mine operating environment is complex, and the flexibility and rapidity of wet spraying trolleys make them perform well in mine tunnel support.
5. Dam slope: The wet spraying trolley can effectively prevent the slope from sliding and enhance the overall stability of the slope in the application of the dam slope.
6. Building foundation pit: In the support operation of the building foundation pit, the wet spraying trolley can quickly build the initial support structure to ensure the safety of the foundation pit.
7. Military engineering: In military engineering, the wet spraying trolley can quickly build a protective structure to improve the protection capability of the project.
Advantages of concrete wet spraying trolley
Compared with traditional small wet spraying machines, concrete wet spraying trolleys have significant advantages:
1. Operation flexibility: The wet spraying trolley can operate flexibly in a complex construction environment and adapt to various terrains and construction requirements.
2. Rapidity: The wet spraying trolley has high spraying efficiency and can complete large-area spraying operations in a short time.
3. Convenience: The wet spraying trolley integrates multiple functions, is easy to operate, and reduces the complexity of manual operation.
4. Economic efficiency: Due to its high spraying efficiency and good quality, the wet spraying trolley can reduce construction costs and improve economic benefits.
5. Safety: The wet spraying trolley has a high degree of automation, which reduces the labor intensity and construction risks of operators.
Improvement of quality and efficiency
The wet spraying trolley has obvious advantages in improving the quality of tunnel shotcrete. By accurately controlling the spraying amount and spraying angle of concrete, the wet spraying trolley can ensure the uniformity and density of the spraying layer, thereby improving the structural strength and durability of the tunnel. At the same time, the efficient operation capacity of the wet spraying trolley greatly improves the construction efficiency and speeds up the progress of the entire project.
The wide application of the wet spraying trolley of concrete not only overcomes the problems of traditional concrete spraying machines, but also significantly improves the construction efficiency and quality, reduces labor intensity and construction costs, and promotes the development of mechanized construction in tunnels and other fields.
