PURPOSE: Retaining supporting is provided to reduce water pollution caused by coffering work and to increase economical effects, by achieving a coffering effect by a closed space. CONSTITUTION: In retaining supporting, a steel pipe sheet-pile(1) is used as a supporting unit member. In the steel pipe sheet-pile, steel pipes(2) arranged parallel are integrally interconnected by an H-steel connection member(4) the edges of which are combined to the peripheral surface of each steel pipe and a connection part(3) is arranged to the steel pipe. The supporting unit members are horizontally connected by mutually combining the connection parts, to form a retaining wall. Supporting unit members vertically arranged are interposed at suitable intervals to make the connection members and steel pipes arranged in the rear of the retaining wall.
