METHOD FOR CONSTRUCTING REVERSELY DRIVEN COLUMN AND REVERSELY DRIVEN COLUMN
To highly accurately and economically construct a reversely driven column in which a column material composed of a steel pipe and a reinforced concrete-made pile body are integrated with each other in an underground trench.SOLUTION: A method for constructing a reversely driven column including a column material composed of a steel pipe and a reinforced concrete-made pile body having a rectangular cross section includes the steps of: excavating the ground, and constructing an underground trench having a rectangular cross section; building a reinforcement cage in the underground trench, and suspending and positioning the column material; inserting a tremie pipe into the underground trench, and arranging the tremie pipe in an internal corner part; and driving concrete into the underground trench using the tremie pipe.SELECTED DRAWING: Figure 4
【課題】鋼管よりなる柱材と鉄筋コンクリート造の杭体とが一体となった逆打ち支柱を、地中溝内で高精度かつ経済的に構築することである【解決手段】鋼管よりなる柱材と鉄筋コンクリート造よりなる矩形断面の杭体とを備える逆打ち支柱の構築方法であって、地盤を掘削し、矩形断面の地中溝を構築する工程と、該地中溝に鉄筋かごを建て込んだのち、前記柱材を吊り下ろし位置決めを行う工程と、トレミー管を前記地中溝に挿入し、入隅部に配置する工程と、前記トレミー管を用いて前記地中溝にコンクリートを打設する工程と、を含む。【選択図】図４
