CONSTRUCTION METHOD OF UNDERGROUND WORK BY COMPLETELY AUTOMATIC BUILDING CONSTRUCTION SYSTEM

摘要

PURPOSE:To provide a construction method of underground work by a completely automatic building construction system capable of promoting greatly work efficiency by making use of columns to install an automatic construction device after the columns in an underground part are constructed. CONSTITUTION:A plurality of pile holes 14 are excavated in the inside surrounded by a continuous underground wall 12, pile reinforced cages are inserted into parts under the excavated bottom 16 of the pile holes 14 to cast pile concretes 18, and underground columns 20 are penetrated and are installed in an unsolidified stage of pile concretes 18. The underground columns 20 are equipped with long columns 20a and short columns 20b. After the pile concretes 18 are solidified, An automatic construction device 22 is installed across a part projecting the long columns 20a from the ground. After the installation of the automatic construction device 22, the inside of the continuous underground wall 12 is excavated, and beam materials 38 conveyed by means of a ceiling crane 30 of the automatic construction device 22 are subsequently installed as parts of the basement first floor, second floor... between the exposed underground columns 20.
