SEWER DETERIORATION PREDICTION SYSTEM AND SEWER DETERIORATION PREDICTION METHOD
PROBLEM TO BE SOLVED: To provide a sewer detection prediction system capable of predicting the deterioration state of a sewer on a span-by-span basis.SOLUTION: A deterioration prediction unit derives life spans or deterioration levels of spans of the same pipe ages which are management objects for a municipality. It allocates the spans to total height at positions of the pipe ages on a Weibull curve figure. It regards pipe ages of intersection positions (Z5, Z6, Z7) of a horizontal line (Y2) from the center in a height direction of each of the allocated spans to a direction increasing the pipe age or a direction decreasing the pipe age and w1 to w3 as indicators indicating soundness of the respective spans, and outputs them to a span deterioration database.SELECTED DRAWING: Figure 14
【課題】下水管渠の劣化状態をスパンごとに予測できる下水管渠劣化予測システムを提供する。【解決手段】劣化予測部は、当該自治体の管理対象である同一の管齢のスパンについて寿命又は劣化度を導き出す。ワイブル曲線図での当該管齢位置における全高に対してこのスパンを割り振る。割り振られた各スパンの高さ方向中央から管齢が増す方向及び管齢が減る方向に延びる横線（Ｙ２）とｗ１乃至ｗ３との交点位置（Ｚ５、Ｚ６、Ｚ７）の管齢を各スパンの健全度を示すものと把握し、スパン劣化データベースに出力する。【選択図】図１４
