Factory price spray concrete machine for tunnel

Factory price spray concrete machine for tunnel also suitable materials for subway stations, slopes and stores, providing long-term stability. It can be used as the final or permanent lining of underground structures. Wodetec Equipment Co., Ltd. is a leading spray concrete machine manufacturers and suppliers in China, and is a unique supplier with ISO 9001: 2008, SGS, and CE certification for this product. is.

Factory price spray concrete machine for tunnel are widely used for road slope protection, civil engineering underground foundations, pool coupling, tunnel excavation, mining operations, hydropower projects, wall coupling, retaining walls and more.

Factory price spray concrete machine for tunnel involve pumping pre-prepared concrete, usually ready-mixed concrete, into the nozzle. Compressed air is introduced into the nozzle and pushes the mixture out to the receiving surface. Wet process procedures generally have less rebound, waste (when material falls to the floor), and dust compared to dry mixing processes. The biggest advantage of the wet mix process is that all the ingredients are mixed with the required water and additives. In addition, a large amount of material can be placed in a shorter time than in the dry process.

Factory price spray concrete machine for tunnel is available that controls the complete process and makes it very fast and easy. Wet spray concrete is traditionally mechanically applied, although manual and mechanical methods are used for the wet spray process. High spray output and large cross section require mechanized work. The shot cleat machine mounted on the wheel is mainly used for working with wet mixes. Unlike traditional concrete pumps, these systems must meet the additional requirement of supplying as constant and therefore continuous concrete flow as possible to ensure uniform spray application.

Factory price spray concrete machine for tunnel is very useful in underground mining (hard rock). The development of underground decline routes is crucial for the movement of heavy equipment, personnel and materials. Shot crates have made these passes safer from falling off the ground.

Factory price spray concrete machine for tunnel using to watch out for:

1. In the process of injection, to prevent water from flowing into the water supply pipe, if a failure such as a pipe blockage or a power outage occurs, the water gate should be shut down immediately and the nozzle should be placed underneath. When working with blocking pipes, you can use the striking method to unclog the feed tube.
2. Operators must wear gas masks, latex gloves and eyeglasses. Dust concentration should be less than 6mg / m3.
3. After injection, water the spray layer once a day for 28 consecutive days.

Operators of shot cleat machines with wheels need special training and should be familiar with the structure and operating principles of shot cleat machines mounted on wheels. They can eliminate common failures and perform normal maintenance.
