Description

A multi-functional impact rock cracking equipment

technical field

The drilling and blasting method produces large noise and serious pollution, and it is easy to cause collapse in tunnels with poor surrounding rock. In special cases, it is strictly forbidden to use drilling. Therefore, the mechanical construction method gradually replaces the drill and blast method. For example, the mechanical construction method must be used in the construction of urban underground tunnels. Mechanical construction methods mainly include rock drilling rigs, shield method and tunnel boring machine construction. The construction cost of shield method is relatively high and it is suitable for long-distance construction.
