PROBLEM TO BE SOLVED: To provide a soil cement structure and its construction method for letting a boundary part of a preceding element and a following element keep sufficient water cut-off properties and strength by a simple process or configuration when constructing the soil cement structure such as an underground continuous wall. SOLUTION: When constructing at least the following element B by this method for constructing the water cut-off wall 10, an excavated hole 28 is dug by using blast furnace slag, fly ash, and an excavation liquid 30 containing bentonite and water and a solidifying liquid 32 containing cement, bentonite, and water is poured into the excavated hole 28 to mix the solidifying liquid 32, the excavation liquid 30, and excavated soil together and harden these mixed solidifying liquid 32, excavation liquid 30, and excavated soil.
