PROCEDIMENTO ED APPARECCHIO PER LA IMPERMEABILIZZAZIONE DEL SOTTOSUOLO MEDIANTE MEMBRANE IMPERMEABILI |
摘要 |
A method for laying subsoil membranes includes dragging a hollow cutting blade through the soil at a predetermined depth, providing a supply of sheeting to the interior of the blade and feeding the sheeting from the interior of the blade through an opening therein. The hollow blade has a cutting edge, a rear edge and an upper section having an upwardly sloping front portion and a downwardly sloping rear portion connected by a center portion. The bottom portion of the blade slopes in an upward direction from its front to form a release angle. The sheet material is fed out of an opening in the rear of the blade. |
