First, after excavating to a predetermined depth with the excavator 12, muddy water is injected into the casing 9. And pull out the casing 9. This operation is repeated for about 3 or 5 pieces to form the excavation hole 1 filled with muddy water. (Step C) A spacer 2 ′ is attached in the excavation hole 1 filled with muddy water so that the tip of the steel sheet pile 2 is not displaced in the excavation hole 1.

When the steel sheet pile 2 is lifted by a crane, the same figure (a), (b)
It is attached as shown in FIG. 1 and is set in the excavation hole 1 by its own weight while being guided by the construction ruler 6. (Step B) In this way, the earth and sand excavated after the steel sheet pile 2 has been built is backfilled around the steel sheet pile 2 by removing boulders with a sieve in the earth and sand loading bucket 8. (Step A) At this time, the muddy water that flows through the tober is injected into the preceding casing 9 by the submersible pump 10.
この発明による矢板の施工方法実施例は以上の通りであ
