Principle of wet spray trolley

Principle of wet spray trolley

At present, wet spray trolley is widely used in railway, highway tunnel, water conservancy and hydropower, subway, mine roadway, military facilities, various underground buildings, emergency rescue and so on. The main technology of the wet spray trolley is to use liquid pressure to send the prefabricated cement to the nozzle through the pipe, then inject compressed gas and accelerator at the nozzle, and then spray the cement to the sprayed surface at a very fast speed, and then quickly Solidify and solidify, thus forming a new type of concrete support structure. The two operations of feeding and shotcrete are completed by the machine, which completely eliminates the health damage to workers caused by dust generated by manual mixing and feeding. Low rebound rate and good shotcrete surface greatly increase the footage of the drilling rig and significantly improve the working speed.

The main difference between concrete wet spraying machine and concrete dry spraying machine

The main difference between concrete wet spraying machine and concrete dry spraying machine

What are the main differences between wet concrete spraying machine and dry concrete spraying machine? Concrete shotcrete machine is a mechanical device, it is through the compressed air concrete in accordance with a certain proportion of mixed together, and then sprayed into the concrete surface, the formation of dense concrete on the surface, so as to achieve the support of concrete. Concrete shotcrete machine is the key equipment of shotcrete, with high degree of mechanization, simple process and high production efficiency, it has been widely used in construction, municipal, railway, mining and other fields. Concrete injectors can usually be divided into two types, one is concrete, one is concrete, the other is cement, one is cement, and the other is cement.

Spray machine performance

Spray machine performance

Spray machine is a kind of environmental protection equipment with wide adaptability, new type of high efficiency and simple operation and maintenance. The equipment has diesel engine drive, central control, and is equipped with a special water pump. Through mechanical stirring, the slurry is made in two or three dimensions by horizontal stirrer. Circulating flow to achieve the mixing of liquid and solid substances. The stirring power of the jet seeder is large, which can ensure that the high-density slurry is fully stirred, and can maintain suspension during spraying, thereby ensuring that the high-density mixed slurry will not be blocked. The sowing machine is suitable for the construction of all kinds of spraying fiber covering materials, and is suitable for highway, railway, highway, embankment and large area greening.

Guest soil spraying machine technology

Guest soil spraying machine technology

With the acceleration of China's urbanization process and the gradual advancement of various development and construction projects, a large number of exposed slopes have appeared. These exposed slopes will not only have a great impact on the original soil and water conservation functions, but also cause landslides and cause great damage to the surrounding ecological environment. regular protection means such as shotcrete anchor, mortar rubble skeleton, cement skeleton and retaining wall can well support the stability of the slope, but because of its low coordination with the surrounding environment, it can not adapt to the modern urban landscape, nor can it meet the aesthetic needs of people. The soil spraying can not only realize ecological restoration, but also protect the environment. The soil spraying technology is to mix the soil with organic matrix, binder, water retaining agent, fertilizer, acid-base regulator, seeds, etc. according to a certain ratio, stir fully by machinery, and then spray the slope with the energy of the soil spraying machine to form a soil layer for plant growth on the slope. After the seeds germinate and grow into a flat, the stability of the slope can be effectively protected, thus quickly restoring vegetation and ecological barriers.

Advantages of tunnel concrete wet spray manipulator

Advantages of tunnel concrete wet spray manipulator

Advantages of tunnel concrete wet spray manipulator 1, save production costs. (1) Material saving: The wet spraying machine is provided with a gate valve for adjusting the blanking rate at the discharge port of the hopper, which can adjust the blanking rate at will according to the spraying speed without causing stirring loss, thus reducing the blanking of workers at one time and preventing a large amount of materials from being spilled during stirring.

Introduction of shotcrete machine

Introduction of shotcrete machine

The shotcrete machine has reasonable structure, humanized design, reliable performance, convenient operation and maintenance, and long service life. No dust, low noise, low rebound rate. This machine greatly reduces the dust near the edge of the machine and the nozzle, improves the working conditions, and reduces the pneumoconiosis disease caused by excessive dust. The device has been patented in three countries. Building plastering is a kind of wet shotcrete construction machinery for railway (highway tunnel), high-rise buildings and diversion culverts. This machine is simple in structure, easy to use and maintain. Unique compression device. There are 10 material cavities inside the rotor of the shotcrete machine, made of special rubber, which can be automatically cleaned by wind vibration to prevent material adhesion.

Wet spraying machine hydraulic system is how to debug

Wet spraying machine hydraulic system is how to debug

How to debug the hydraulic system of wet spraying machine When the pressure reducing valve of the wet spraying machine cannot work normally, after the main motor starts to work, the device starts to enter the water pump, the device cannot work, and the pressure of the hydraulic gauge is 0. Common problems and measures: ① When the remote control of the device is turned on, the pump stop and pump start switches on the control panel will fail. Open the control panel, the safety valve will not be energized, and the power supply on the safety valve will not light up, making the device unable to work. Turn off the remote switch. ② After the safety valve is energized, the current indicator on the safety valve will light up.
