The Initial Support Of The Tunnel Adopts The Wet Shotcrete Operation Of The Concrete Wet Shotcrete Machine

Wet shotcrete, a new technology in the field of tunnel construction, is gradually gaining popularity alongside the commonly used dry shotcrete in my country. This innovative method offers several advantages during the shotcrete process. Firstly, it significantly enhances construction efficiency, allowing for a smoother and quicker operation. Furthermore, the reduced production of dust and low rebound rate contribute to a safer working environment for workers involved in the construction. Additionally, wet shotcrete proves to be cost-effective due to its lower consumption cost.

By utilizing wet shotcrete technology, the drawbacks of both dry spraying and wet spraying methods can be effectively addressed. This approach ensures not only the safety of workers but also improves the quality of injection construction. Moreover, it substantially reduces the construction period of tunnel projects. With the application of wet shotcrete, the overall safety and efficiency in tunnel construction can be greatly enhanced, meeting the requirements and demands of modern construction technology.

To provide support for the tunnel, the first step taken is to utilize the wet shotcrete operation via a concrete wet shotcrete machine. Once the excavation of the tunnel is done, a layer of 4cm thick concrete is sprayed onto the rock surface to seal it. This is followed by the laying of bolts, erected steel frames, and steel mesh to prevent the shot rocks from falling. After cleaning the concrete surface, it is resprayed again to achieve the designed thickness. This process is crucial in ensuring the safety and stability of the tunnel structure.

There are various types of concrete wet spraying machines, including small machines, hydraulic pumping machines, rotor piston machines, vehicle-mounted machines, and wet spraying manipulators. These machines play a crucial role in tunnel engineering construction as they provide integral support for the entire project, ensuring the quality of work and promoting safety. By utilizing a wet spraying machine, workers are able to ensure the initial support necessary for a successful tunnel construction, thereby boosting overall construction quality. Whether it is enhancing support capacity or improving the quality of the construction itself, concrete wet spraying machines are essential tools in tunnel engineering.
