Abstract

Изобретение относитс  к гидротехническому строительству и может быть применено при создании противофильтрационных облицовок каналов. Цель изобретени  - повышение качества работ за счет устранени  обезвоживани  пластичного состава. Мелкодисперсное облако водоотталкивающей смеси 4, вспрыснутое под давлением через отверсти  2 в подплиточное пространство, обволакивает поверхность железобетонных плит 1. В результате при нагнетании инъектирующего состава из песчано-цементной смеси не происходит обезвоживани  состава и уменьшени  его пластичности, а также преждевременного схватывани  и закупоривани  пространства между плитой и основанием. 2 ил.The invention relates to hydraulic construction and can be applied when creating impervious channel linings. The purpose of the invention is to improve the quality of work by eliminating the dehydration of the plastic composition. A fine cloud of water-repellent mixture 4, injected under pressure through the holes 2 into the sub-trench space, envelops the surface of reinforced concrete slabs 1. As a result, when injection of the injection composition from the sand-cement mixture does not occur, the composition dehydrates and decreases its plasticity, as well as premature setting and clogging slab and base. 2 Il.
