UNDERGROUND CONTINUOUS WALL CONSTRUCTION

PURPOSE:To prevent decrease of the function due to corrosion and enable easy arrangement of reinforcements even when the above space of an excavated hole is narrow, by inserting uncured cold setting FRP ropes as vertical reinforcements and cured FRP bar materials as horizontal reinforcements. CONSTITUTION:A plurality of uncured FRP ropes 1 as vertical reinforcements are arranged at every specified interval and a plurality of cured FRP bar materials 2 are arranged at every specified interval in the direction crossing in right angles with the ropes. The intersections are united with strings. Weights 6 are fixed at the front ends thereof and suspended down from both sides of the longer sides of the excavated hole 7. At that time, both ends of bridging materials 3 are united together with the cured FRP bar materials 2 at the upper side of excavation hole 7 to form a reinforcements-cage. In this way, it can be easily inserted even in a curved excavation hole. Since it is lighter than steel reinforcements, the transportation cost can be remarkably reduced.
