摘要： PROBLEM TO BE SOLVED: To provide underground water stream maintenance construction method capable of maintening an underground water stream for water deeper than an excavated bottom face, and capable of unnecessitating a special ground space and designing low cost while securing a long stability including securement of an underground water stream independent at respective plurality of mermeable strata and clogging measures. SOLUTION: A natural ground having permeable strata 14, 16, 18 in the underground is excavated to construct a continuous underground wall 12. The natural ground surrounded by the continuous underground wall 12 is open cut in the condition that underground water is cut off by the continuous underground wall 12 and after an underground structure 10 has been erected or during it is erected, fluidization of the underground water is planned in the underground water stream maintenance construction method. When the continuous underground wall is constructed, a process in which a cylindrical body 20 is inserted vertically to form a hollow part in the continuous underground wall 12 and a process planning fluidization of the underground water by forming water flowing holes 24a, 24b by cutting the continuous underground wall 12 in the position corresponding to water permeable layers 14, 16, 18 from the cylindrical body 20 after the continuous underground wall 12 has been hardened, are included in the method.
