本発明は鋼矢板の表面にプラスチックシートを貼付する
方法及び装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method and apparatus for pasting a plastic sheet onto the surface of a steel sheet pile.
〈従来の技術〉
−Ｃに土木・建設用鋼矢板を使用するには、多数の鋼矢
板を連続的に地中に打し込み、河川や海岸などの護岸と
建設現場での土砂掘削時の地盤固めに用いる。<Conventional technology> In order to use steel sheet piles for civil engineering and construction in -C, a large number of steel sheet piles are continuously driven into the ground, and are used for protection against rivers, coasts, etc. and during earth and sand excavation at construction sites. Used for ground consolidation.
この鋼矢板は特に河川，海岸に使用した場合、水位ある

生じた鋼矢板は製品化できない。Several methods have been used to cover this plastic sheet, but the one that generally requires technical skill is the use of force [
1. When pasting the sheets one after another on the heated steel sheet pile,
The problem is how to attach the material without leaving any air bubbles between the sheet I and the steel sheet pile. If air bubbles remain between the sheet and the steel sheet pile, the sheet will complete the pasting process in a swollen state, and the sheet and the steel sheet pile will not come into close contact with each other, making it impossible to obtain the desired adhesive strength. Therefore, steel sheet piles with bubbles cannot be commercialized.
