Abstract
Provision of integrated rock tunnel high-speed drilling equipment and methods for its use. [Solution] The tunneling equipment in this invention has a multi-functional drill that integrates drilling and anchoring installed on one side of the cantilever-type tunneling machine body, and a temporary support mechanism 4 installed above the vibrating cutting section 2. Before rock crushing by the tunneling equipment, a deep hole is formed in the rock to be crushed using the multi-functional drill 3, and the deep hole is further enlarged and crushed using the pulsating crushing system 8 to weaken the rock body strength. After that, the rock body is milled using the vibrating cutting section, and finally, anchor support is provided on the rock body using the multi-functional drill and temporary support device to provide a safe working environment. This equipment and technology simplifies the conventional tunnel excavation process into a series of continuous processes, significantly improving the efficiency of tunnel rock body excavation and saving costs.
