Martial Arts Secrets of Sany Wet Spraying Machine

Golden Tunnel Construction Good Partner

Meeting

How big is the domestic tunnel market?？

Let's look at the following data first.：

In recent years, the mileage of tunnels under construction in China has increased by about 11.%；About 3,100 new tunnels will be added in 2023；《National Highway Network Planning（2013-2030）》Express，The total scale of the national highway network planning is 40.10,000 kilometers；2020《Outline of Railway Advance Planning for Transportation Power in the New Era》Point out，By 2035, the national railway network is planned to be 200,000 kilometers.，Including 70000 kilometers of high-speed rail……

With the continuous increase of national tunnel engineering quantity,，For highways/Railway tunnel、Slope、Mine Roadway、Water Conservancy/Tunnels and culverts for hydropower、Construction machinery and equipment for subway and other support operations become“Hot and fragrant baboons”，Widely praised by the market。Among，As“Tunnel concrete spraying expert”Sany Wet Spraying Machine has been on the market since，Sales continue to rise，The construction environment of tunnel shotcrete is improved，The safety and health of operators are guaranteed.，The construction cost is reduced.。

What are the high quality characteristics of Sany Wet Spraying Machine?，Make it stand out from the crowd，Win market praise at one stroke？Don't blink，Coming up，One for you“Reveal the secret”。
