METHOD FOR CONSTRUCTING AGRICULTURAL WATER PIPE
To provide a method for constructing an agricultural water pipe excellent in safety and workability, capable of preventing groundwater and sand from flowing out during an irrigation season, preventing land subsidence, and suppressing adhesion of soil and sand when a steel sheet pile is pulled out and movement of soil and sand after the steel sheet pile is pulled out.SOLUTION: The method comprises: a steel sheet pile pressing step of pressing adjacent steel sheet piles 2 in parallel right and left in a top view of an agricultural water pipe 1 to be constructed underground to a predetermined depth; a ground improvement step of injecting a chemical solution 4 into the ground between the opposing steel sheet piles pressed in parallel to improve the soil quality of the ground; a steel sheet pile wall construction step of excavating the ground between the steel sheet piles into which the chemical solution has been injected to the predetermined depth to construct a steel sheet pile wall 21; an irrigation pipe installation step of installing the agricultural water pipe is installed; and a ground leveling step of backfilling the excavated soil in the excavated area and pulling out the steel sheet piles to level the ground.SELECTED DRAWING: Figure 1
【課題】 灌漑期において、地下水や砂分の流出を防止するとともに、地盤沈下を防止でき、鋼矢板の引き抜き時の土砂の付着や、引き抜き後の土砂の移動も抑制可能な、安全性・施工性に優れた農業用水管の施工方法を提供する。【解決手段】 地中に構築すべき農業用水管１の上面視左右平行に、所定の深度まで鋼矢板２を隣接して圧入する鋼矢板圧入工程と、平行に圧入した向かい合う鋼矢板の間の地盤に薬液４を注入して地盤の土質を改良する地盤改良工程と、薬液を注入した鋼矢板の間の地盤を所定の深度まで掘削して鋼矢板壁２１を構築する鋼矢板壁構築工程と、農業用水管を配設する用水管配設工程と、掘削箇所に掘削土を埋め戻し、鋼矢板を引き抜き整地する整地工程とを有することを特徴とする。【選択図】図１
