SH25H hydrauilc pneumatically actuated rig is one new type pipe-foundation construction facility.It is mainly for reliably driling original cook .This machine centralizes the technical merits of the rotary driling rig, the air-actuated down-holes and the hydraulic diaphragm wall grab.
This machine structure with many superior processing properties is to drive the down-hole hammer impact the rock.aim to smash the rock party and cut the rock to pleces, discharged by air-lift in reverse circulation way and air direct circulation way. It can realize the fast continuous driling function to the big cross-section original rock. The host machine can conveniently exchange the job practices between the driling,the impactng and the driling with the CFA.
