Q:What is the difference between artificial wet spray concrete and mechanical wet spray concrete?
Rebound material and dust on the spray of a great impact on the rebound of the stone easy to hurt the shooter, so the general wind pressure will not be very full, mechanical jet can completely avoid this problem, the wind pressure can make the dense layer
Q:What should you pay attention to when spraying concrete with a wet spray machine for tunnel works?
Therefore, this process needs to be noted that it is necessary to spray evenly, and leave no gaps.
Q:Are there any differences between concrete dry and wet spray?
Dry spray: dry spray is the aggregate, cement and quick-setting agent according to a certain proportion of dry mixing evenly, and then into the jet, with compressed air to dry aggregate in the hose was suspended in the state pressure to the gun,
Q:What kind of machinery does the concrete wet spray machine belong to?
Engineering machinery is an important part of China's equipment industry.
Q:What is the difference between concrete wet spray machine and dry spray machine?
Wet spraying machine is a vegetation greening machinery and equipment, mainly used for highway (railway) slope greening, slope protection, mountain governance, mine green, desertification, landfill and other projects.
Q:What is the working principle of concrete wet spray machine?
The plunger concrete pump is used as the basic body of the wet concrete jet, and the nozzle is installed at the outlet of the pipe and the compressed air is introduced there, and the concrete is ejected.
Q:What is the difference between dry spray and wet spray?
- where water is added to the material - sprayed onto the spray surface under wind pressure
Q:What is concrete concrete and net spray concrete?
Plain concrete - a structure made of concrete that is free of tendons or non-configured reinforced concrete.
Q:What is the use of concrete wet spray machine
1, greatly reducing the machine and the nozzle outside the dust concentration, eliminating the harm to the health of workers.
Q:What is the difference between pouring concrete and shotcrete?
It is advisable to prevent the template and the freshly poured concrete from direct sunlight, to control the temperature of the concrete into the mold template and the rebar and the local temperature in the vicinity of not more than 40 ° C.
