What machinery is used to spray concrete?
Shotcrete is a construction technology widely used in tunnels, mines, slope support and other projects. Its high efficiency and flexibility make it an important process in modern construction. Choosing the right injection machinery is critical to project quality and efficiency. This article will combine hot topics and hot content in the past 10 days to give you a detailed introduction to the types, characteristics and applicable scenarios of machinery used in shotcrete.
1. Main types of shotcrete machinery
Shotcrete machinery is mainly divided into three types: dry spraying machine, wet spraying machine and tide spraying machine. Each type has its own advantages and disadvantages and is suitable for different construction environments. Here's how they compare:
| Mechanical type | Working principle | advantage | shortcoming | Applicable scenarios |
|---|---|---|---|---|
| dry spray machine | The dry mix is sprayed by compressed air and water is added at the nozzle | Simple equipment, low cost, long conveying distance | Large dust, high rebound rate, unstable quality | Small projects, temporary support |
| Wet spray machine | Concrete mixed with water in advance is sprayed through a high-pressure pump | Less dust, low rebound rate, stable quality | Complex equipment, high cost, short conveying distance | Large tunnels and high-demand projects |
| Squirting machine | Between dry spraying and wet spraying, the moisture content of the mixture is low | Less dust, moderate rebound rate, medium cost | Moisture content needs to be strictly controlled | medium scale projects |
2. Recommended brands of popular shotcrete machinery
According to recent market research and user feedback, the following are several brands and models of shotcrete machinery that have attracted much attention:
| brand | model | type | Features | Reference price (10,000 yuan) |
|---|---|---|---|---|
| Putzmeister | SP 11 | Wet spray machine | High efficiency, low rebound, intelligent control | 80-120 |
| Sany Heavy Industry | HPS 3016 | Wet spray machine | Domestic products with high cost performance and easy maintenance | 50-80 |
| XCMG | XZPS 30 | Squirting machine | Strong adaptability and simple operation | 30-50 |
| China Railway Equipment | GHP3010 | dry spray machine | Lightweight and suitable for narrow spaces | 15-25 |
3. How to choose the appropriate shotcrete machinery
When choosing shotcrete machinery, you need to consider the following factors:
1.Project scale: It is recommended to choose a wet spray machine for large-scale projects, while dry spray or tide spray machines can be considered for small and medium-sized projects.
2.construction environment: In narrow spaces or high-dust environments, you need to choose lightweight, low-dust equipment.
3.Budget: The cost of a wet spray machine is higher, but it can save materials and improve quality in the long run.
4.Technical requirements: High-precision projects require the selection of intelligently controlled equipment.
4. Recent industry hot spots and trends
1.Intelligent injection machinery: With the development of artificial intelligence technology, more and more injection machinery are equipped with automatic control and remote monitoring functions, which improves construction efficiency and safety.
2.Increased environmental protection requirements: The control of construction dust is becoming stricter in various places, and the market share of wet spray machines is gradually expanding.
3.The rise of domestic equipment: Domestic brands represented by Sany Heavy Industry and XCMG are gradually catching up with imported brands in terms of performance and services, and are more cost-effective.
5. Summary
The choice of shotcrete machinery directly affects the quality and efficiency of the project. Dry spraying machines, wet spraying machines and tide spraying machines each have their own advantages and disadvantages, which need to be decided according to specific needs. The recent trends in industry intelligence and environmental protection are obvious, and the performance of domestic equipment is also worthy of attention.
