Abstract

PURPOSE: To reduce adhesion resistance of a cutter head by a method wherein a low adhesion blade made of ultrahigh molecular weight polyethylene and the like is fixed at the whole area of the front part of a face plate attached to the front end of a cutter head drum. CONSTITUTION: Low adhesion blades 8 are fixed at the whole area of the front part of a face plate 4 attached to the front end part of a cutter head drum 3 of a cutter head 2 rotatably arranged at the front end part of an excavation head 1. The low adhesion blade 8 is formed of a low adhesion material, such as ultrahigh molecular weight polyethylene and fluororesin. This constitution prevents a stop of rotation of the cutter head 2 due to the overload of cutter torque even when quality of a ground is highly adhesive.
