摘要

PURPOSE: To heighten rigidity, enable construction work while avoiding nonconformity such as the ground surface protrudes or sinks even by a concrete beam, construct a structure in an economical cross section, and efficiently construct a horizontal board-shaped structure. ;CONSTITUTION: A shielding machine 1 is made to depart in the horizontal direction underground, and a drift is excavated while discharging work face earth and sand in the direction Y almost perpendicular to the excavation advancing direction X in a horizontal plane containing the excavation advancing direction X of the shielding machine 1. In succession, the shielding machine 1 is propelled, and materials to build a board shaped structure are carried in a space formed in the rear of the shielding machine 1 from the direction Y almost perpendicular to the excavation advancing direction X, and are assembled, and a horizontal board-shaped structure is constructed.;COPYRIGHT: (C)1996,JPO
