<p>A method for coupling an earth pipe into the ground when utilizing an apparatus that has a drilling device including a casing part and a drilling unit inside thereof. The drilling unit includes a first drilling member for drilling a center hole and a second drilling member for reaming the center hole for the casing part. The casing part is arranged to be drawn into the hole by the first and/or second drilling member. After drilling a hole for the earth pipe and lifting up the first drilling member, a solidifying mass is led to the bottom of the hole to couple the earth pipe to the surrounding ground. The solidifying mass is brought in the casing part utilizing a flow-through assembly at a lower end of the casing part into a space between an outer surface of the casing part and the hole. Also an apparatus operating.</p> |
