Sany wet spraying machine martial arts secrets

In recent years, the mileage of tunnels under construction in China has increased by about 11% annually. About 3,100 new tunnels will be added in 2023; According to the National Highway Network Plan (2013-2030), the total planned scale of the national highway network is 401,000 kilometers, and the 2020 Outline of the Advance Planning for Railways in the New Era of Transportation Power points out that by 2035, the national railway network will be planned to be 200,000 kilometers, including 70,000 kilometers of high-speed railways......

With the continuous increase in the amount of national tunnels, construction machinery and equipment used for road/railway tunnels, slopes, mine roadways, water conservancy/hydropower tunnels and culverts, subways and other support operations have become "sought-after sweets" and are widely praised by the market. Among them, as a "tunnel concrete spraying expert" of SanyWet sprayerSince its launch, sales have continued to rise, improving the construction environment of tunnel shotcrete, ensuring the safety and health of workers, and reducing construction costs.

What are the high-quality characteristics of Sany wet spraying machine that make it stand out from many brands and win market praise in one fell swoop? Don't blink, next, "unveil" for you one by one.

Unique pumping system more efficient,Inherit Sany ace concrete pumping technologyIndustry-leading, energy-efficient "not picky eater"

Peace of mind：intelligent fault self-diagnosis,Automatic prompt for maintenance,Let you use it worry-free

In the past two years, the state's investment in roads and railways has grown rapidly. The 14th Five-Year Plan states that by 2035, the total length of domestic high-speed railways is expected to increase to 240,000 kilometers, and the length of expressways is expected to reach 460,000 kilometers. At the same time, Article 6 of the "Nine Regulations on Tunnel Construction Safety", the specific implementation rules require that the railway double-track high-risk and above tunnels must be sprayed with wet spray and manipulators for the use of step construction projects.

Sany Heavy Industry closely follows the pace of national strategy and planning, actively participates in the construction of national railway and highway network, lays out the manufacturing of wet spraying machine products, and contributes to the development of tunnel wet spraying engineering.
