Cement shotcrete gunite machine for Tunnel Thailand
Shotcrete and various reinforcement and fixing systems effectively stabilize earthworks excavation. Drilling with shotcrete-stabilized soil has advantages over traditional timber and steel support techniques. Shot cleats are also great for supporting tunnels and quarries. Provides early ground support after blasting or excavation, provides early strength development, ground stabilization, and stress relaxation flexibility, and provides the ability to adapt to the natural and irregular contours of the ground without formwork. However, it is an ideal choice for any tunnel.
Cement shotcrete gunite machine for Tunnel Thailand is also the perfect material for subway stations, slopes, and shops, providing long-term stability. Can be used as the final or permanent lining of underground structures.
Cement shotcrete gunite machines are widely used in road slope protection, civilian underground foundations, shot cleat swimming pools, tunnel construction, mining work, hydropower projects, shot cleat walls, retaining walls, and more.
Cement shotcrete gunite machine Thailand involves pumping pre-prepared concrete (usually ready-mixed concrete) to the nozzle. Compressed air is introduced into the nozzle and pushes the mixture out to the receiving surface. Wet process processes generally have less spring back, waste (if the material falls to the floor), and dust than dry-mix processes. The biggest advantage of the wet mixing process is that all the ingredients are mixed with the required water and additives, allowing more quantities to be placed in less time compared to dry processes.
Cement shotcrete gunite machine for Tunnel Thailand controls the entire process, making it extremely fast and easy. Wet shotcretes are traditionally machined, although wet shotcretes use both manual and mechanical methods. If the amount of spray is large and the cross-section is large, mechanical work is required. The shot cleat machine mounted on the wheel is mainly used for processing wet mixes. Unlike traditional concrete pumps, these systems must meet the additional requirement of supplying concrete flow as consistently and therefore continuously as possible to ensure uniform spray application.
Cement shotcrete gunite machine for Tunnel Thailand is very useful in underground mining (hard rock). The development of a descent passage to the ground is important for the movement of heavy equipment, people, and materials. Shot crates keep these passes safely from falling off the ground.
Cement shotcrete gunite machine for Tunnel Thailand prevention:
1.If a failure such as clogging of a pipe or a power failure occurs during the water injection process, immediately close the water gate and lower the nozzle to prevent water from flowing into the water supply pipe. If the pipe is clogged, you can clear the supply pipe by tapping it.
2.The operator must wear a gas mask, latex gloves, and eyeglasses. The dust concentration should be less than 6 mg / m3.
3.After injection, water the spray layer once a day for 28 consecutive days.
