PURPOSE: To make construction work easily by inserting a steel sheet-pile from the upper side of a slope face downwards into the slope face at a new angle to be corrected, digging the removing sediment outside the steel sheet-pile, and fixing the steel sheet-pile to the ground by means of an anchor bolt.
CONSTITUTION: A steel sheet-pile 2 for the first stage H1 is driven downwards from the uppermost shoulder of a slope face 1. Next, the ground is digged by an amount of below half of the length of the driven steel sheet-pile 2, sediment is removed to the front surface of the steel sheet-pile, and cement mortar is spraying onto the digged surface. A hole is drilled from the outside of the steel sheet-pile into the inside of a banking. Then an anchor bolt 3 is inserted into the hole, curing agent 4 is filled around the bolt 3 to fix it to the ground, and a supporting member is attached to the head of the bolt 3. After driving the steel sheet-pile 2 for the second stage H2, the same work procedure is repeated.
