Market demand for wet spraying machines

Concrete wet spraying machine is the core equipment in shotcrete construction, and is widely used in shotcrete support projects related to construction, municipal administration, railway and highway tunnels, foundation pits, mines, slopes, etc. Common concrete wet spraying     Machines are generally divided into several categories, such as hydraulic concrete wet spraying machine, rotor concrete wet spraying machine, vehicle-mounted concrete wet spraying machine, and concrete wet spraying manipulator.

Compared with dry spraying machine, concrete wet spraying machine has the advantages of effectively reducing rebound, reducing dust, increasing the thickness of the first spraying layer, improving the quality of shotcrete, and high production efficiency. Concrete wet spraying machine is widely used in engineering construction in the fields of mine tunnels, railways, highway tunnels, water conservancy culverts, underground projects, high-rise building foundation pits, military projects, etc.

With the continuous advancement of urbanization in my country and the continuous increase in investment in infrastructure construction such as high-speed railways, ordinary railways, highways, and water conservancy and hydropower construction, as well as the increasingly stringent national environmental protection policies, downstream industries use concrete wet spraying machines instead of dry spraying machines, and the market demand for concrete wet spraying machines continues to increase, gradually becoming the mainstream equipment for concrete spraying.

In the future, my country's macro-economy is expected to maintain steady development, and the downstream engineering construction industry will continue to develop, thereby driving the growth of demand for wet shotcrete machines. Under the situation of stricter environmental protection policies and more complex engineering construction projects, the number of intelligent, efficient and high-quality wet shotcrete machines will gradually increase, and the overall quality level of wet shotcrete machines will gradually improve. The development prospects of wet shotcrete machines are very broad.

At present, domestic shotcrete equipment is a combination of dry spraying machines and wet spraying machines. However, in recent years, with the development of tooling technology and the widespread promotion of wet spraying technology, concrete wet spraying trolleys have been rapidly promoted and developed in China, and the use of concrete wet spraying trolleys has received more and more attention. The main reasons are as follows:

1. Compared with the dry spraying process, wet spraying technology has the following four obvious advantages: First, it can greatly reduce dust concentration and eliminate the harm to workers' health; second, it has high production efficiency, and the concrete wet spraying trolley can reach 10~30 cubic meters per hour; third, it has low rebound. With the wet spraying technology, the rebound rate can be reduced to less than 10%; fourth, the construction quality is high. During wet spraying, the water-cement ratio is easy to control, which can greatly improve the homogeneity of concrete.

2. Domestic environmental protection requirements are becoming increasingly stringent, and national policies encourage mechanized construction. Various design documents and construction specifications clearly state that wet spraying technology should be used.

3. With the annual increase in labor costs, the advantages of mechanized operation methods are becoming more and more obvious. The construction efficiency of concrete wet spraying trolleys is more than doubled compared to manual labor.

4. The R&D capabilities of domestic concrete spraying trolley manufacturers have been improved, their products have become more mature, and their products have been standardized and serialized, which are increasingly favored by the market.

5. The perfect after-sales service system provides strong technical support for the operation and maintenance of the equipment, and further promotes the application of concrete spraying trolleys.

Concrete spraying trolleys have the advantages of high degree of construction mechanization, high work efficiency, small rebound, strong construction safety, good working environment, and significant economic benefits. Concrete spraying trolleys are widely used in spraying concrete support operations in the construction of railway tunnels, highway tunnels, water conservancy culverts, mine tunnels, dam slopes, building foundation pits and military engineering.

With the enhancement of people's environmental awareness and the improvement of requirements for the quality of sprayed concrete, more and more concrete spraying trolleys will be put into use, and the development prospects of concrete spraying trolleys are very broad.
