ROLLER SHEET PILE TYPE CAISSON FOUNDATION WORK

摘要

PURPOSE:To exactly and easily perform an open caisson foundation work by reducing the friction between caisson and the ground by attaching a roller shee pile to the tip of the cassion and penetrating the sheet pile under the ground. CONSTITUTION:A caisson 1 is vertically erected on a settling position, sheet pile L-shaped web steel plates 2-3 are built in L-shaped sheet pile receiver 3, and the periphery of the caisson 1 is surrounded by a roller sheet pile 2. Under the condition, the inside of the caisson 1 is excavated and the caisson 1 is settled while balancing loading to the caisson 1. Since an edge is cut in the area between the caisson 1 and the ground, the settling of the caisson 1 under the ground is easy and therefore, an open caisson foundation work can be performed quickly and exactly.
