PURPOSE:To simplify the structure of concrete protective walls as well as make easier the construction work on site by a method in which steel tubular piles are driven in two rows at equal intervals and covered with casings of an angular cylinder form having coupling grooves on its three ways and a filling material is packed into spaces formed by laying wall plates over the mutually facing grooves. CONSTITUTION:A necessary number of steel tubular piles 1 are driven in two rows at an equal interval, angularly cylindrical concrete casings 3 are fitted on the piles 1 while adjusting them in such a way as to mutually face the coupling grooves 3b and then supported on a receiving base 2. Then, concrete wall plates 4 are laid across the coupling grooves 3b, an iron bar cage 6 is inserted into the steel tubular pile 1, and concrete 5 is placed. Then, concrete 7 is placed between the steel tubular piles 1 and the inner surfaces 3a of the casings 3, and filling material, e.g., soil, etc., is then packed in the spaces surrounded by the wall plates and the casings 3. By this, semi-permanent structures can be constructed in shortened construction periods. |
