Abstract

The invention relates to a hydraulic sinker-drill unit for drilling in soil and rock, which has a rotary engine which is situated at the top of the drilling shaft and drives a drilling pipe connected to a drilling crown 1 to rotate the drilling crown 1, and a hydraulic hammer 3 arranged in association with the drilling crown for producing the hammer action on the drilling crown 1. The invention is characterized by a hydraulic pump which is located in the drilling pipe in association with the hydraulic hammer 3 and is arranged so as to drive the hydraulic hammer. <IMAGE>
