摘要： PURPOSE:To make the construction of an underground beam easier by a method in which a pipeline extending from a pit excavated in the ground toward the horizontal direction is set, reinforcing bars extending along the pipeline are set in the pipeline, and concrete is placed in the pipeline to construct a beam. CONSTITUTION:A pit 22 is excavated in the side of an existing facility 20, and a pipe 24 is set in the horizontal direction by a pusher. A pipeline 26 is formed by a corresponding distance between preset pit-excavating positions 32 and 34, an expandable part with a jack is set on the pipe 24 and advanced with the pipe 24, and a pipeline 26 is formed to the position 34. The pusher and the jack are removed, in-situ piles 42 are formed in the positions 32 and 34, and pits 44 and 46 are excavated in the positions 32 and 34 by removing the cutting edge. A reinforcing bar cage 48 is set in the pipeline 26, reinforcing bar cages 50 are set in the pits 44 and 46, and concrete is placed to form a beam in the pipeline 26 and also to form a strut in the pit 22. A number of latticed beams are likewise constructed below the facility 20.

摘要： PURPOSE:To permit construction work for prestressed continuous underground wall to be performed safely and exactly without the exertion of influence on other operations by a method in which the ends of the steel materials of a reinforcing bar cage are connected and tensed in a coupler casing. CONSTITUTION:A reinforcing bar cage 5 with many PC steel materials 3 and a coupler casing 21 are alternately arranged in a trench 2 in the ground 1, and the ends of the steel materials 3 are set in the casing 21. Underwater concrete 6 is placed by excluding the inside of the casing 21 and cured, and the steel materials 3 are connected with each other and tensed in the casing 21. Concrete is then placed into the casing 21. The PC steel materials 3 can thus be easily and exactly connected and tensed, and prestress can also be introduced into the whole of the continuous underground wall. The whole construction period can be shortened because there is no concurrence between the operations in the casing 21 and the other operations.
