Title:
FLOTATION PREVENTION METHOD OF UNDERGROUND BURIED STRUCTURE AND STRUCTURE THEREOF
Document Type and Number:
Japanese Patent JP2017106292
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method and its device being realistic, inexpensive and highly reliable without causing re-excavation, and serializing-integrating a pipeline (a line structure) and an inspection port such as a manhole (a point structure)(forming in a bead shape), as a flotation prevention method of an underground-buried structure in an earthquake.SOLUTION: A method is provided by including a process of installing a tension material connection device 4 for integrating by tensioning-connecting a tension material 3, on the required place inside in an inspection port 2 such as a manhole for arranging the tension material 3 inserted into a part of not hindering the original function such as flowing water in a straight line, bending, a head drop and a confluent part on an inner surface of a pipeline 1, in an underground-buried structure constituted of the pipeline 1 and the inspection port 2 such as the manhole. Desirably, the tension material 3 is carbon fiber, aramid fiber and glass fiber being a continuous fiber tension material, and while, the tension material connection device 4 is any of materials such as an anticorrosion coating steel material and a stainless steel material.SELECTED DRAWING: Figure 1
