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 gaps. 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.

A pipe 6 communicating both holes is 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 positions of the through holes 5 are determined by the groundwater veins. In the through-hole 5, drainage material 7 is disposed inside the through-hole in order to allow only groundwater to flow and block earth and sand. A rubber cap 8 is attached to the through-hole of the rib 2 on the ground side. During the construction, the cap 8 is held in the opening so that mortar or the like does not enter the through hole 5. The opening of the rib 2 on the construction side holds the drainage material 7 as packed. The cap 8 is detachably attached so that the cap 8 can be removed after construction. A wire 9 for removing the cap 8 is attached to the cap and extends to the upper end of the rib 2.

Excavate trenches with continuous walls on both sides of the ground to be constructed.
The sheet pile 1 is suspended by a crane in the groove, and is arranged to form a continuous wall. The cap 8 of the sheet pile is held as it is attached.
Inject mortar between the groove and the sheet pile 1 and into the sheet pile,
The sheet pile 1 is fixed to the ground. After the construction work, at least the mortar is injected so that the cap 8 and the wire 9 are easily broken so that the cap can be removed so that the cap can be removed.

る。<B> Burial of the continuous wall Excavation of the ground to be constructed between the continuous walls composed of the sheet pile 1 is performed.
The continuous wall prevents groundwater inflow and ground collapse. The excavation ground is excavated to the required depth for the structure. After the construction is completed, the wire 8 is pulled to remove the cap 8.
Is removed from the through hole 5 so that groundwater can pass through the through hole 5. Then, the excavated ground is backfilled. 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.
