Wall-casting system in ground - uses end shuttering walls in sections aligned and clamped together beforehand

摘要

The system casts a wall in the ground using two parallel dry guide walls (1) sepd. the thickness of the wall to be formed. Between them, a tench is then due by an excavator guided by the walls. Shuttering (4) is then mounted at the trench ends and concrete is poured in. Each shuttering wall is assembled beforehand from sections fitted end-to-end, aligned and clamped together. Guides on the outside are provided for the excavator when digging the next trench section. The sections are freed from each other, after which each is detached from the concrete poured by vertical movement of the excavator guided in it. USE - Avoids need for tall and heavy shuttering sections, or for a special wedge tool for knocking out.
