Claims

[Scope of utility model registration request]

A head attached to the tip of a lining element with a box-shaped cross section that has joints on both sides, protrudes in the propulsion direction between the joints on the side adjacent to the existing preceding element, and slides between the joints of the preceding element. ``Head'' of an element for lining, characterized by having a plow-removing member.
