XWV90 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 cross-section aperture of the section tunnel is only 8m, so it is difficult for large excavator machines and equipment to carry out work. The project can be carried out by milling and digging method and its small and medium-sized excavator crushing excavation. According to the research and grasp of the industry market, the tunnel hydraulic milling and digging machines and equipment are selected to carry out the excavation of the section tunnel. There are two main types of Aikat milling and digging machine: horizontal milling and digging machine and vertical iron excavator; They can be installed in 2-350m and 3-451 data digger.

According to the indoor space regulations of the construction specifications of the fusion equipment, only small and medium-sized excavators can be selected for the industrial equipment used in the tunnel. According to the geological structure of the transverse safety passage and the positive line tunnel, it is the medium weathered mudstone layer. The rock cracks in this layer are relatively developed. The layer thickness is about 40cm, and it is horizontal towards all over the place. Some of them are up to 23.6Mpa, and the cracks of surrounding rock regolith are relatively developed. And interfissure water is rich and colorful. The working effect of track hydraulic milling and digging machine of each type and specification of Aikat in different rock layer strength is analyzed.
