The underground continuous wall is formed by connecting sheet piles as shown in FIGS. <A> Sheet Pile The sheet pile 1 has a structure in which steel ribs 2 are arranged in parallel, and a main plate 3 is connected to the ribs 2 as spacers in the gap. The sheet pile 1 includes a plurality of types in addition to the double claw type. In order to connect the sheet piles, connecting ribs 4 are provided on both sides of the rib. The connecting claws 4 are connected to each other to form a continuous wall.

Pipes 6 for connecting the holes are provided at the positions of the corresponding holes in the ribs 2 on both sides. Groundwater can flow from one side of the continuous wall to the other side through the through hole 5. The number and position of the through-holes 5 are determined by the groundwater veins and the like. A cap 7 is attached to the opening of the through hole of the rib 2 on the construction side of the underground structure. The cap 7 has a screw portion 8 fixed to the rib 2.
Is cut off. (Refer to FIGS. 2A and 2B.) After the construction, the cap 7 faces the construction side and can be easily removed by hand.

For this purpose, trenches where continuous walls are installed are excavated on the ground on both sides. The sheet pile 1 is suspended by a crane in the groove, and is arranged to construct a continuous wall. The cap 7 is left attached to the sheet pile 1. Mortar is injected between the groove and the sheet pile 1 and into the sheet pile to fix the sheet pile 1 to the ground.

The excavation ground is excavated to the required depth for the structure. The sheet pile 1 is fixed by beams 9 and firmly held on the ground. After the construction of the structure is completed, the cap 7 is removed by hand, and groundwater is allowed to pass through the through-hole 5 to refill the excavated ground. Although the sheet pile 1 is buried, since it has the through-holes 5, groundwater can flow, and problems such as interruption of groundwater can be solved. During the construction work, the upstream water level 10 of the groundwater rises, but after removing the cap and refilling the excavation ground, the water level 10 gradually decreases, and the water level on the downstream side rises. Return to the water level.
