Slope surface protection, foundation pit protection, tunnel shotcrete, etc. need to be used.Foundation pit support shotcrete machineAnd air compressors, shotcrete machines on the market generally have dry spraying machines, tidal spraying machines, wet spraying machines, etc. The air compressors matched with these shotcrete machines are generally 13-24 cubic air compressors.

At present, in the aspect of environmental protection, the foundation pit support spray machine wet spray machine is recommend, which has the characteristics of small rebound, less pollution, good spray effect, but the price is relative to the dry spray machine, the price is expensive. At present, there are mainly the following types of wet spraying machines on the market: the conveying distance of dry spraying machines and spraying machines can reach more than 100 meters, only 13 square meters and 8 kilograms of air compressors can be used, while the conveying distance of wet spraying machines can only reach 60-80 meters due to material problems, so the selection of larger air compressors can only match this distance.

Whether the shotcrete machine alone cannot carry out slope support operations, it needs to be used in conjunction with the corresponding air compressor. At present, there are generally two types of air compressors equipped with shotcrete machines on the market: fixed and mobile. This air compressor is an electric screw air compressor, which is commonly used for 13 square 8kg, 16 square 8kg and 24 square 8kg. Because the air compressor is expensive, if the amount of work is small, you can rent one in the local area. The dry wet spraying machine is well understood. The feeding material is dry, and the delivered dry material is sprayed with concrete through the spray pipe to the nozzle addition and addition water pipe to achieve the spray effect.

The shotcreting process of the foundation pit support shotcreting machine: after each work, the machine should be cleaned, the surface of the sealing plate and the rotor lining plate should be cleaned, and the wear between the sealing plate and the rotor should be checked. if the steel ribs have been used to be flush with the rubber surface, the sealing plate should be polished, and the ribs should be removed or replaced with new plates. Hand operation should wear hats, goggles, protective clothing, etc. Cement machines are widely used in culverts, railways, highways, water conservancy projects, underground projects and coal mines, mines, and roadway concrete construction. According to the different plastic spraying materials (different plastic spraying materials), the motor rotation can be adjusted to change the spraying.

No. 00 butter is required for the support shotcrete machine. One day, two times, put the butter of the cylinder into the butter mouth. Butter needs to be added once a day before the S-pipe. Like the cost of the shotcrete pump is relatively high, so the service life of the small shotcrete machine should be paid attention. In the use of small shotcrete machine, not only to ensure the normal working load, but also to consider the impact of harmful factors. Water-based materials, fire materials, thermal insulation materials, sound-absorbing materials and other water-soluble materials. Operation steps and requirements of multi-functional mortar spraying machine: 1. Before starting up each shift, hold the oil pump several times and inject oil into the transmission part. 2. After turning on the power supply, first start the main motor and check whether the spiral direction of the tape conveying is consistent with the direction indicated by the arrow. If not, the power phase line should be replaced.

Common faults of foundation pit support shotcrete machine 1. The shotcrete operation should be kept uniform, generally 30-60cm. 2. In order to make the inkjet effect better, it is necessary to accumulate experience in daily work to play a role. 3. The painting temperature should be controlled at 20-30 ℃, otherwise it will affect the adhesion of the coating, thereby affecting the spraying effect. Common faults of concrete shotcrete machine for deep foundation pit.
