LIQUEFACTION COUNTERMEASURE METHOD OF EXISTING BURIED PIPE
PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure method of an existing buried pipe in which the liquefaction countermeasure for lifelines such as a gas pipe, a clean water pipe and a sewer pipe, in residential areas such as subdivisions where roads and detached houses are closely built, can be simply and economically performed.SOLUTION: In the upper part of an existing buried pipe 1, two or more injection pipes 2 are installed in a pipe axis direction of the existing buried pipe 1 at regular intervals. An injection material is injected in the ground of an upper part or a side part of the existing buried pipe 1 through each of the injection pipes 2, and the injection material is made to flow down and penetrate in a side and/or a bottom of the existing buried pipe 1, and thereby is consolidated so as to encompass the buried pipe 1 in a penetrated/consolidated area. Accordingly, a consolidation body integrated with the existing buried pipe 1 is formed in the side and/or the bottom of the existing buried pipe 1, and the weight of the existing buried pipe 1 is increased, and thereby the lift of the existing buried pipe 1 with the liquefaction is suppressed.
【課題】道路や戸建て住宅が密集して建つ分譲地などの住宅地等における、ガス管、上水管、下水管などのライフライン等の液状化対策を簡便、かつ経済的に行うことのできる既設埋設管の液状化対策工法を提供する。【解決手段】既設埋設管１の上方に複数の注入管２を既設埋設管１の管軸方向に一定の間隔を開けて設置する。各注入管２を通じて既設埋設管１上部または側部の地盤中に注入材を注入し、既設埋設管１の側方および/または底部に注入材を流下浸透させて浸透固結領域内に埋設管１が包含するように固結せしめ、既設埋設管１の側方および/または底部に既設埋設管１と一体の固結体を形成して既設埋設管１の重量を増大させることにより液状化に伴う既設埋設管1の浮き上がりを抑制する。【選択図】図20
