FLOTATION PREVENTION METHOD OF UNDERGROUND BURIED STRUCTURE AND STRUCTURE THEREOF
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
【課題】地震時における地中埋設構造物の浮上防止方法として、再掘削を伴わないとともに現実的で安価かつ信頼性が高く、管路（線構造物）とマンホール等点検口（点構造物）を一連・一体化（数珠状化）する方法及びその装置を提供するものである。【解決手段】管路１とマンホール等点検口２により構成される地中埋設構造物において、管路１内面で流水等の本来機能を阻害しない部分に挿入した緊張材３を、直線、屈曲、落差、合流部に配置されるマンホール等点検口２の内の必要箇所内部において、緊張材３を緊張・連結し一体化するための緊張材連結装置４を設置する工程を含むことを特徴とする方法が提供される。好ましくは、緊張材３は、連続繊維緊張材である炭素繊維、アラミド繊維、ガラス繊維、一方、緊張材連結装置４は、防食塗装鋼材、ステンレス鋼材などの材料のいずれかである。【選択図】図１
