Abstract

PURPOSE:To perform a cutting work with a high efficiency by a method which a sheathing wall constructed of a low-strength plastic material where a shield penetrates through a pit is reinforced by a steel material having an antifrictional layer on its surface, the steel material is drawn out, and the penetrating portion is cut off. CONSTITUTION:A sheathing wall 2 is constructed around a pit 1, and the main sheathing wall 3 is constructed inside the wall 2. At a place to be removed later of the sheathing wall 2, reinforcing steel materials 4 are buried with a low- strength plastic material. That is, the sheathing wall 2 is constructed of a low- strength plastic material, such as soil concrete, lean-mix concrete, etc., into which reinforcing steel materials 4, e.g., H-shaped steels, etc., having an untifrictional layer with an antifrictional material, e.g., asphalt or resin, on their surfaces, are buried. When the shield A comes near the sheathing wall 2, the reinforcing steel materials 4 are drawn out by a jack, etc., cement milk is injected into the hole formed by drawing out the steel materials 4 to fortify the portions other than the removed portion as needed, and then the predetermined portion B of the sheathing wall is cut off.
