[0002] During drilling construction, the problem of drilling flushing fluid leakage often occurs, which causes accidents of drill sticking and drill burial, resulting in increased drilling costs. When encountering a larger leakage channel, a core tube is often used to hold mud balls and send them to the leakage channel. The core tube is then lifted out of the borehole and then re-inserted into the borehole with a plug at the bottom. The mud balls remaining in the borehole are squeezed into the leakage channel around the borehole through impact tamping, thereby achieving the purpose of plugging the leakage channel. This process often requires manual work by staff, and the steps are cumbersome and time-consuming. Therefore, a tamping device for stopping cement balls in the borehole is urgently needed.
