Installation method of stratified settlement meter and stratified settlement measurement system
Document Type and Number:
Japanese Patent JP6296867
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an installation method for a stratified settlement gauge and a stratified settlement measuring system that may be installed easily, of which the stratified settlement gauge is not damaged due to excavation, and is capable of measuring stratified settlement simultaneously with underground work by an inverted construction method, and is therefore capable of measuring axial compression amount of a basement column only with the stratified settlement gauge.SOLUTION: In an inverted construction method, a protective tube 2 is fixed on a basement column 1, and after erecting the basement column 1 with the protective tube 2 fixed, a rod 6a of a drilling machine 6 is inserted into the protective tube 2 for drilling to the depth for installing an anchor 9 at the lowest tier of a stratified settlement gauge. Then, a measuring wire 8 and a plurality of anchors 9 linked with the wire are inserted into a hole 7 thus formed, and each of the anchors 9 is fixed at a prescribed depth position. At the same time, a displacement gauge or a converter 10 is installed with the upper end of the measuring wire 8 linked to an upper part of the protective tube 2.
