The solidification material restoration manner null in cast-in-place type foundation work

摘要

PURPOSE: To enhance greatly the easiness and effectiveness in such works as filling of solidifying material, control of the top faces, and management of the penetrating amount of an injecting means and to mechanize and automate the whole arrangement. ;CONSTITUTION: A flexible hose 2 is dangled in a work site, for example in an excavation groove 3, for pouring in a solidifying material 7, wherein the hose is wound up by a hose winch 1 in association with elevation of the top face level. A differential pressure sensor 16 is installed at the bottom of the hose to sense the differential pressure of the injected solidifying material from the muddy water 8 to be substituted, and the top face level of the solidifying material is measured from this differential pressure obtained.;COPYRIGHT: (C)1993,JPO&Japio
