ROADBED IMPROVEMENT METHOD AND IMPROVED ROADBED
To provide a roadbed improvement method capable of easily improving a roadbed without removal of a track or the roadbed.SOLUTION: A roadbed improvement method is a method that improves, by a filling material F1, a roadbed 6 supporting a track bed 5. The roadbed improvement method comprises an injected hole forming step of forming, on the track bed 5, an injected hole 5b that injects the filling material F1, a filling material flowing down step of causing the filling material F1 to flow down naturally from the injected hole 5b, and a filling material infiltrating step of causing the filling material F1 to infiltrate into the roadbed 6. The filling material infiltrating step comprises a step of causing the filling material F1 of ultrafine particle cement milk containing a hardener into the roadbed 6. An improved roadbed 7 is a portion where the roadbed 6 supporting the track bed 5 is improved by the filling material F1. A filling roadbed layer 7a is formed by causing this filling material F1 into the roadbed 6 by natural flow-down from the injected hole 5b filled back after the injection of the filling material F1.SELECTED DRAWING: Figure 7
【課題】軌道や路盤の撤去を伴わずに路盤を簡単に改良することができる路盤改良工法及び改良路盤を提供する。【解決手段】路盤改良工法は、道床５を支持する路盤６をてん充材Ｆ1によって改良する工法である。路盤改良工法は、てん充材Ｆ1を注入する注入孔５ｂを道床５に形成する注入孔形成工程と、注入孔５ｂからてん充材Ｆ1を自然流下させるてん充材流下工程と、てん充材Ｆ1を路盤６に浸透させるてん充材浸透工程とを含む。てん充材浸透工程は、硬化材を含有する超微粒子セメントミルクのてん充材Ｆ1を路盤６に浸透させる工程を含む。改良路盤７は、道床５を支持する路盤６がてん充材Ｆ1によって改良された部分である。てん充路盤層７ａは、てん充材Ｆ1の注入後に埋め戻される注入孔５ｂから、このてん充材Ｆ1を自然流下によって路盤６に浸透させて形成される。【選択図】図７
