Application
Protection Engineering: Dry and wet shotcrete machine can be used for spraying fire-retardant coatings on various steel structures, as well as repairing building chimneys and various hot melting furnaces in refractory material projects;
Geotechnical Engineering: In geotechnical engineering such as slopes, dams, tunnels, reservoirs, swimming pools, deep foundation pits, irrigation, and retaining wall breakwaters, dry and wet shotcrete machine is used to spray concrete to provide additional support and protection;
Mining Engineering: In underground projects such as mine tunnels and mine shafts, dry shotcrete machine is used for main support and lining to improve the safety of mining projects;
Bridge construction: In bridge construction, PZ-7 dry and wet shotcrete machine is used to spray concrete to enhance the stability and durability of bridge structures.
Impact on the Environment
Dust pollution: Dry and wet shotcrete machine generates a lot of dust during the spraying process, which can pollute the environment.
Health risks: Due to the serious dust pollution, dry shotcrete machines also pose a threat to workers' health during the spraying process.
Construction environment requirements: During the construction process, the dry and wet shotcrete spraying machine needs to ensure that the surrounding environment is relatively closed to avoid the dry powder from flying and affecting the surrounding air quality. Therefore, the construction environment requirements are relatively high, which limits its application scope.
Therefore, if there are strict requirements on the construction environment, it is recommended to use a wet shotcrete machine.

Introduction
The PZ-7 dry and wet shotcrete machine, also known as a shotcrete machine or gunite rig, is a specialized piece of equipment used in the construction industry to apply wet concrete mixes at high velocity onto surfaces such as walls, ceilings, and floors. This technique, often referred to as shotcreting, allows for the rapid and efficient application of concrete, creating a monolithic structure that adheres strongly to the substrate. The machine typically consists of a hopper to hold the concrete mixture, a pump to generate the necessary pressure, and a nozzle through which the concrete is sprayed. Gunite machines can be pneumatic, hydraulic, or electric, with each type offering specific advantages depending on the project requirements. They are widely used in tunneling, mining, slope stabilization, and repair works where traditional concreting methods would be impractical or too time-consuming.
