Abstract

PURPOSE: To raise the accuracy of finishing by a method in which a cylindrical formwork of thin steel plate, etc., is inserted and set in an excavated pit, and while supporting the formwork from inside by a slide supporter inserted into the formwork in a vertically movable manner, concrete is placed to the outside of the formwork.
CONSTITUTION: A pit A is formed by excavation work, and the pit A is filled up with mud water B. Cage-like reinforcing bar units 2 are each attached to a plurality of form units 1. The first stage bottomed unit 1 is penetrated into the pit A from a working base C, and while supporting the unit 1 by the buoyancy of mud water B, the upper stage unit 1 is connected with the unit 2. Water is then injected into the unit 1 to set it on a given position. A floating supporter 3 is then penetrated to the bottom of the pit A, and while supporting the lower part of a formwork 10 by the inside, concrete 4 is placed to the outside of the formwork 10. These processes are repeated. The finishing accuracy can be raised, and the construction cost can be reduced.
