Recently, the Guangzhou Metro Line 11 and Line 18 have fully promoted the two-wheel milling construction process during the construction. The project introduced 30 sets of two-wheel milling equipment, of which 10 Xugong two-wheel milling machines are eye-catching "Xu Gongjin" "Sparkling debut, competing on the same stage, brilliant, Xugong two-wheel milling machine solves the problem of mud-rock paste wheel in subway construction, the construction efficiency is 3-4 m / h, far more than similar products.
Xugong two-wheel milling cracks the construction problem
The customer has the most say in product quality. Customer Li Zong, using the purchased imported two-wheel milling machine, has a paste wheel and no footage during the construction of mudstone formation, and can not be used normally. Instead, the newly purchased XCMG XTC80/55 is used. Two-wheel milling does not have this problem. In the early stage of market research, the company developed a 1.2-meter standard tooth milling wheel for mudstone lithology and mud lubrication and softening during construction, as well as mud wheel milling and slipping caused by plugging. The milling wheel adopts standard teeth suitable for soft rock cutting such as mudstone. It applies German BETEK wear-resistant nails and cutting alloy cutter heads. By properly arranging the standard tooth cutting position and quantity, mudstone plugs and paste wheels are avoided. The single-tooth cutting force increases the milling speed, avoids the abnormal wear of the milling wheel and the milling dead zone, and improves the service life. These new units are equipped to be built in mudstone formations with efficiencies of 3-4 m/h, which greatly exceeds customer expectations. (This article is from Xugong Foundation)
