[0002] Water-grinding drilling is a new type of construction method. It is often used in some construction environments where blasting construction cannot be adopted, some sites are limited, and they are close to important equipment and facilities. Because of its high site applicability, low environmental impact, small vibration and disturbance to surrounding buildings, no restrictions on the supply of pyrotechnics, simple operation, stable progress, good safety and other characteristics, it cannot be replaced under some special working conditions. Water-grinding drills are widely used in construction fields such as house construction foundation construction and rock geological pile foundation excavation. The water-grinding drill mainly includes a drill barrel and a motor. The motor drives the drill barrel to rotate to achieve drilling. In the process of use, when encountering rock formations, a water-grinding drill is often used to drill the rock formations and collect core samples. A core grabbing tool is required.
