Claims

[Scope of Claim for Utility Model Registration] (1) A guide pipe with a cutter is attached to the tip of the buried pipe, a propulsion device is provided at the rear end of the buried pipe, and a cutter head is rotatably provided in the cutter to cut excavated soil. In the buried pipe propulsion device, which conveys the material backward in the lead pipe and buried pipe, and at the same time pushes out the buried pipe and leader using the propulsion device to dig, a chamber is formed inside the cutter mouth by the cutter wheel of the cutter head and the partition wall inside the cutter mouth. Then, the tips of the water supply pipe and the drain pipe, whose rear ends are guided to the rear end of the buried pipe through the leading pipe and the buried pipe, are opened in the chamber, and a crushing blade is provided protruding from the back of the cutter wheel and the front of the bulkhead. An excavation device in a propulsion device characterized in that a gravel crushing device is formed in a chamber by a combination of these crushing blades. (2) A cutter head with a rib material protruding from the front of the cutter wheel with the apex at the center, and a cutting blade arranged on this rib material.
