发明名称 GUIDE TUBE FACILITATING INSERTION OF STEEL PIPE PILE AND WALLED STEEL PIPE PILE CONSTRUCTING METHOD USING THE SAME
摘要 The present invention relates to a guiding pipe used in an installation method for a wall steel pipe. Specifically, the present invention is to a guiding pipe facilitating the insertion of a steel pipe. The steel pipe installed on the placed ground can be installed by being guided into a first hollow unit formed in a body so that the multiple steel pipes are vertically installed. The guiding pipe guides a connection body formed in the steel pipe penetrating and inserted in the first hollow unit by a first cutting unit so that the connection unit is vertically inserted into an insertion hole formed on the other steel pipe penetrating and inserted into a second hollow unit by a second cutting unit. So, the multiple steel pipes installed on the ground can be vertically installed to each other. According to the present invention, the guiding pipe facilitating the insertion of the steel pipe is formed in a column shape with a predetermined length, wherein an upper part and a lower part are open. The guiding pipe has: the first hollow unit formed in order for the steel pipe to be inserted inside; a pipe-shaped body having the first cutting unit with the predetermined intervals on the outer surface in the longitudinal direction; and an extension member connected to the first cutting unit to be connected to the body in the longitudinal direction, wherein a joint unit formed in the steel pipe penetrates and is inserted into the extension member. The joint unit includes: the insertion hole protruding from one side of the steel pipe; and the connection body formed on the other side of the steel pipe and protruding to be connected to the other steel pipe.
