Abstract

PURPOSE: To sink a caisson horizontally and smoothly, by putting jacks among the cutting edge portions of the caisson and the support ground, and by operating the jacks while excavating the ground.
CONSTITUTION: When a location of base rock is deep or the base rock inclines, support bodies 7, which are easy to be broken as bentonite concrete, are created, and a caisson 3 is directly placed on the base rock on the support bodies when the ground is shallow. Jacks 5 are installed into a number of concave portions 4a beforehand formed to cutting edge portions 4, regions surrounded by means of the inwalls of the cutting edge portions and the support ground A around the bottomes of the jacks are primarily excavated or broken, and the caisson is supported by means of the jacks. The regions corresponding to the cutting edge portions are secondarily excavated or broken, and the whole caisson is sunk while horizontally keeping it by operating the jacks.
