Abstract

PURPOSE: To reduce frictional force by supplying an anti-friction material such as solution type high water absorbing resin to an inlet for anti-friction material arranged at a shield skin plate and filling it between the skin plate and peripheral ground through an anti-friction material spreading guide groove. CONSTITUTION: An anti-friction material consisting of a solution type high water absorbing resin or a water absorbing gel of the same resin is stored into an anti-friction material tank 1 installed in a shield machine or the like, and it is supplied by means of a pump 2 to an anti-friction material inlet 6 located near the facing side of a shield skin plate 5 through a filling pipe 4 and a quantitative distributor 7. Also on the peripheral surface of a plate 5, a fan-shaped anti-friction material spreading guide groove is provided. Then, the anti-friction material is filled into the inlet 6 and turned into a gel state by absorbing water to an water absorbing resin and is supplied to a gap between the guide groove and peripheral ground 9 and is uniformly extended to the peripheral surface of a plate 5. In this way, the frictional force can be decreased.
