BASE PILE CONSTRUCTION METHOD

PURPOSE:To make it possible to safely construct base piles without spoiling traffic function on the ground by erecting temporary support piles at proper intervals, building up a temporary platform with temporary rails and a cover plate and mounting those apparatuses used for the installation of these piles on the platform. CONSTITUTION:Temporary support piles 3 are erected at proper intervals, and a temporary beam 4 is installed on them. In addition, temporary rails 10 are placed at proper intervals thereon, and a cover plate 11 is placed along the whole surface of the rails to construct a temporary platform A. In this case, openings, which are necessary for the construction of base piles 17 are made at the parts of positions of column member installation. In addition, temporary enclosing frames are constructed in hanging with temporary enclosures 13 of enough size for these base piles 17. In the next step, on the temporary platform A, necessary apparatuses such as a crawler crane 12 are placed. Construction works for these base piles are made on the temporary platform A. By using this method, the construction of these base piles can be carried out safely and effectively without influence of traffic conditions.
