Abstract
Abstract The invention concerns a wall remaining tight despite possible displacements of its panels because of the terrain. To this end, it involves joints formed of cylindrical parts 2 and 3, connected by a band 6 consisting of at least one fold 7, of such a kind that the allowed displacement of the panels 16 and 17 entails a deviation less than the length of the unfolded band 6. The invention applies to all tight walls.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
In a tight wall having a plurality of vertically oriented end-to-end panels embedded in a hardened liquid grout and including joints between consecutive panels, the improvement comprising, said joints being extensible and capable of changing their shape without constraint, each joint including two parallel and tubular parts connected laterally by a band, said tubular parts adapted to fit into and be retained by hollow tubular sections in each panel, said band comprising at least one longitudinal fold dimensioned such that at a maximum range of displacement between the consecutive panels, the increase in the distance separating the tubular parts of the joint is, at most, equal to the width of the unfolded band, and an auxiliary plunger tube of smaller diameter removably disposed in the interior of each tubular part.
Claim 2
Dependent Claim
