Abstract

La présente invention concerne un procédé de réalisation d'un pilot en béton coulé sur place en utilisant une chemise de coffrage. Selon le procédé, après avoir protégé un treillis d'armature avec une chemise de coffrage, la chemise de coffrage dans laquelle est coulé le béton est insérée dans un trou de forage de pilot pour éviter que le treillis d'armature assemblé soit déformé. De même, du fait que la chemise de coffrage est mise en vibration tout en étant tirée vers l'extérieur après le coulage et le façonnage du béton dans la chemise de coffrage, le béton peut être façonné facilement, il ne se produit pas de séparation de matériau et la forme du pilot en béton peut être totalement maintenue. De même, comme de légers impacts sont appliqués après l'insertion de la chemise de coffrage et seule la chemise de coffrage est tirée vers l'extérieur après la séparation d'une semelle inférieure, les boues sur l'extrémité avant peuvent être facilement traitées.
