XWV220 Vertical Drum Cutter

The XW milling and excavating machine can be installed on any type of hydraulic excavator, efficiently replacing general configurations such as digging buckets, crushing hammers, and hydraulic shears. It is applied in multiple fields such as open-pit coal mines, tunnel excavation and contour correction, channel groove milling, asphalt concrete pavement milling, rock permafrost milling, and tree root milling. The milling and excavating machine provides a new construction method for tunnel excavation.

Features of XW milling and excavation machine:

1. Wide range of milling and excavation;

2. Low vibration and low noise;

3. Accurately control construction;

4. The material excavated by milling has a small and uniform particle size, which can be directly used as backfill material;

5. Good safety;

6. Simple structure and convenient use.

The secondary lining construction of the section tunnel needs to be carried out before the linkage test of Chengmianle high-speed railway, and the ground settlement control is within 2.5mm. Considering the uniqueness of ground collapse control of the newly built Mianle high-speed railway, including the underpass tunnel of Chengluo Avenue, etc. The non-engineering blasting excavation method of hydraulic milling and excavating machine should be selected to carry out the construction, and the centralized excavation method commonly used in the construction of non-engineering blasting excavation should be compared with the hydrogeology and overall design status of the project. The total length of the cross safety channel and its section tunnel are 43m and 50m respectively, and the route is short, and considering the construction period, it is not suitable to choose the equipment. Such as TBM, boring machine, etc.

It is not divided into TBM method in drilling and blasting method, milling and digging method and double-arm boring machine excavation method, etc. Milling and digging method is the mine hydraulic milling and digging machine assembled on the hydraulic excavator, used in tunnel excavation and renovation of the wheel corridor, cave, cross hole excavation, etc., especially suitable for the area not suitable for engineering blasting construction, at the same time, the tunnel structure specifications and industrial equipment high efficiency and cost analysis report.
