[0002] With the continuous development of transportation engineering, tunnel construction projects have increased year by year, but they will face various construction difficulties. Traditional tunnel excavation uses mechanical methods and blasting methods, which are relatively efficient, but for tunnels with limited construction space and inaccessible to mechanical excavation equipment, manual excavation can only be used. Generally, small machines such as pneumatic picks, electric picks, and shovels are used for manual excavation, but for full-section hard rock tunnels, these small machines are less efficient and increase construction costs. Therefore, in order to improve construction efficiency, water drills are used for excavation, and hydraulic splitters are used to split the rock mass for excavation. This method does not require excavation of the entire excavation section. The rock mass can be removed by coring the boundary holes, greatly improving excavation efficiency.
