FIELD: construction.SUBSTANCE: method to erect a solid reinforced concrete wall in soil, including arrangement of a fore shaft, separation of a trench into separate divisions and erection of solid reinforced concrete sections in each division, at the same time erection of the solid reinforced concrete section in each division includes excavation in the division under protection of the thixotropic clayey suspension, manufacturing of a reinforcement frame and its lowering into the division for the design depth, fixation of the reinforcement frame on the fore shaft, concreting of the section and drainage of the clayey suspension from the division, differing by the fact that during erection of the solid reinforced concrete section in each division after excavation in the division and manufacturing of the reinforcement frame they manufacture a combined module, placing the reinforcement frame into a flexible non-detachable formwork in the form of a volume case open on top from waterproof geosynthetic material, for instance, geomembrane, the combined module is lowered into a division for the design depth and fixed on the foreshaft. Lowering of the combined module into the division is carried out simultaneously with pumping of the clayey suspension from it, thus replacing the pumped clayey suspension with the combined module, and the section is concreted by the method of vertically moving pipe or a concrete pump into the inner cavity of the combined module after its fixation on the foreshaft.EFFECT: increased strength of an erected wall in soil, reduced material intensity and labour intensiveness of its erection.5 dwg |
