horizontal lonfrinage for shielding excavation to agoges

摘要

the invention relates to a longitudinal beam for supporting horizontal dig site to ditches, uno palplanse or other such elements in the consolidated devices trenchesconsolidation of walls of two by two and willing can be maintainedin at a certain distance by spraituri arranged perpendicular to the longitudinal axis of the trench.in the case of traversarii with dig santurilor pipelines, etc.slab, longitudinal folding reazema heads of bolts around the axial vertical on one console connected jointly with a shoe clamping profile c, which allows alsothe initial orientation angle consolidarilor girl, including a right angle.preferably, the beams consist of parts which can be mutually shifted longitudinally about possibility of fitting length thus to site conditions.
