Abstract

PURPOSE: To obtain a construction method, enabling to construct continuous wall at depth of even 100m at underground, and to remove the inter-lock members after the concrete being hardened, while providing the improved efficiency of excavating works.
CONSTITUTION: After completing excavation, steel partitioning plates 1 in the excavated groove A at the tunnel head with interval as required, are arranged, while inter-lock members 3 being contacted with the ground at excavated tunnel head are set, the jack 5 in between the partitioning plates 1 and inter-lock members 3 is installed to support the partitioning plates 1 to protect itself from concrete pressure. Following the above procedures, concrete 7 is deposited at the excavated groove A, after the concrete 7 is hardened, the inter-lock members 3 are removed by releasing the jack 5, and the succeeding excavation work is started.
