MARINE FOUNDATION JET SYSTEM AND THE METHOD USING IT

摘要

The present invention relates to a device for treating a marine foundation using jet injection and an installation method for the same. To achieve this, the device for treating a marine foundation according to the present invention includes a guide leader installed on a barge; a rope sheave on the top of the guide leader to allow a wire rope to be wound on it; and a casing pipe at the bottom of the wire rope to be vertically moved. The casing pipe is made of a multi-pipe structure comprising a fast water current pipe, a compressed air pipe, and a mortar pipe to allow a fast water current, compressed air, and mortar to flow through, respectively. A mortar outlet is formed at the bottom of the mortar pipe to allow mortar to be vertically injected. A claw member is formed at the bottom of the casing pipe.
