erection of structures with use of metal piles, predominantly water-development works. SUBSTANCE: piling wall is made of prefabricated members of wave-shaped profile in plan, each having flanges arranged on both sides of longitudinal axis of wall in parallel to this axis with displacement one relative to another and interlinked by inclined walls positioned at obtuse angle to flanges parallel to longitudinal axis with formation of extreme inclined semi-walls whose free ends carry cam and fitting forming lock joints. Each fitting is located on outer and cam on inner surface of proper semi-wall. Relation of distance between inclined walls measured along longitudinal axis of wall to distance between flanges arranged on different sides of longitudinal axis of wall, in parallel to it and measured along normal to longitudinal axis of wall lies within bounds from 0.8 to 1.5. Flanges located on different sides of longitudinal axis of wall can have equal width. Each prefabricated member may have one flange less on one side of longitudinal axis of wall than on the other side of longitudinal axis of wall. EFFECT: reduced labor input, enhanced productivity in manufacture of welded piling members and in erection of piling walls, increased specific bearing capacity of piling walls. 3 cl, 2 dwg |
