Milling and dredging machine for tunnel machinery

Application scenario

Tunnel, roadway: tunneling and wall, top, corner, contour, groove and other treatment;

Road engineering: cutting or digging of concrete structures, side gully, slope and ancillary facilities, cleaning of damaged cement or asphalt pavement, etc.;

Hydraulic engineering: concrete structure treatment, river bed cleaning, damaged structures cleaning or demolition, etc.;

Municipal engineering: pipeline trench, foundation, structure excavation or treatment, damaged municipal facilities cleaning or removal, etc.

In the medium and low hardness of rocks such as weathered rock, tuff maximum up to 25 ~ 40m3/h(with the density of the rock, the degree of fragmentation is different), Guangdong small milling and digging machine, can also be milling and digging no reinforcement or a small number of reinforcement concrete, the use of the 300 tons of the milling and digging machine, small milling and digging machine equipment, Concrete with steel bars less than 30mm in diameter can be easily milled.

1. Milling excavator instead of blasting construction, to avoid rock strength reduction, structural loosening, local rupture and other adverse conditions caused by blasting vibration. It is beneficial to protect the original self-supporting capacity of rock mass and not easy to cause large area collapse.

2. In tunnel construction operations, it can replace the very expensive tunnelling machine, shield tunneling machine and other machinery, and greatly reduce the construction cost; The milling and dredging machine is very effective in mining the following rocks: rocks with low hardness; Weathered rock; High hardness but layered structure of rock milling can reach 80-120 tons per hour (depending on the hardness of the rock); Milling and digging machine can replace excavator construction well, and can protect the environment well.

At the same time, the company can provide the core power drive module components of milling and digging machine equipment, such as rotor assembly, cylinder block, stator, wave ring, distribution shaft, torque module, etc.
