COMBINATION HAMMER WITH WATER HAMMER

摘要

The present invention relates to a cluster hammer combined with a water hammer, which comprises: a case; multiple water hammers installed in a circumferential direction in the case; an air lifting sucking stones broken by excavation of the water hammer; and an air supply part supplying air to the air lifting. The case is manufactured to be empty, and a water insertion pipe is inserted and installed in a lower direction at a center of an upper plane of the case, and a water supply path is installed radially in the water insertion pipe to supply water to the multiple water hammers installed in the circumferential direction. The cluster hammer of the present invention has the remarkable effect of not causing boiling in the water without discharging compressed air outside (lower part of bit) and solving a direct reason as to degradation of drilling efficiency by hindering discharge of slime, by using the water hammer instead of an air hammer in the cluster hammer.
