ASSEMBLING METHOD FOR RETAINING WALL-CONSTRUCTING FORM UNIT AND ITS RISE-PREVENTING PLATE

摘要

PURPOSE: To prevent a form unit from rising, and to accurately hold an inclination of the form unit, by connecting front and rear form units with metallic wire rods at regular intervals, and by arranging hard plates such as steel plates, each of which has a plurality of air vent holes thereon, between the wire rods. ;CONSTITUTION: In the case where a concrete-made retaining wall is constructed, a space 8 between a front form unit 2 and a rear form unit 3 is filled with ready mixed concrete 9 thrown from above, one after another from the bottom of the space 8. At this time, the ready mixed concrete 9 is filled through places where hard plate 7 are not arranged. In this case, the condition that the ready- mixed concrete 9 is temporarily stored on the hard plates 7 occurs, and force depressing downward metallic wire rods 5 holding the hard plate 7 at their end parts acts by its load. In this way, the rise of the front form unit 2 is restricted, and the concrete-made retaining wall having a designed inclination can be obtained.;COPYRIGHT: (C)1996,JPO
