PROBLEM TO BE SOLVED: To secure stability without lengthening a bank body and furthermore, facilitate maintenance.;SOLUTION: In a first process, an upper part of a constructed ready-made bank body 2 is excavated up to a predetermined level L1, or a construction-expected bank body 2 is put in a state of interrupting construction in the height of the predetermined level L1 by leaving an upper part on the basis of a design plan. Next, in a second process, a geogrid 5 having a predetermined tensile strength characteristic is laid on an excavation surface (an upper surface) 8 of the bank body 2 of lacking this upper part. Next, in a third process, banking S1 and S2 is formed on the geogrid 5 laid on the excavation surface 8 of the bank body 2. Next, in a fourth processing, an impervious material 6 having impervious performance is laid on a banked surface of the bank body 2, and this impervious material 6 is connected to the geogrid 5. After laying the geogrid 5 on an upstream side slope 2A of the bank body 2, a water impermeable protective material 7 is laid in a part of a design flood water level or less on this geogrid 5.;COPYRIGHT: (C)2007,JPO&INPIT
