METHOD FOR CONSTRUCTING UNDERGROUND CONTINUOUS WALL

PURPOSE:To enhance the withstanding strength and toughness of a joint so as to enhance reliability and to freely adjust the holding force of the horizontal bars of a panel that follows and to prevent the horizontal bars from holding in excess by building a reinforcing cage for the following panel, and widening narrow end horizontal bars, and laying the bars on top of the horizontal bars of the preceding panels without gaps. CONSTITUTION:Channeled guide rails 10 are provided to the vertical insides of the ends of the horizontal bars 5 of a panel that follows. Hooks 9a, 9a formed at both ends of a plate 9 narrower than the width between the unbound horizontal bars 5, 5 are inserted into the guide rails 10 and the horizontal bars 5 are narrowed to such a degree that they can be forcibly restored. The horizontal bars 5 are constructed between the horizontal bars of the ends of the preceding panel and then the plate 9 is extracted from above the ground to return the space between the horizontal bars 5, 5 to initial width.
