Claims (2)

1. Способ подготовки основания, включающий образование скважин с установкой инъекторов, замачивание, уплотнение и армирование массива грунта твердеющим раствором через гидроразрыв, отличающийся тем, что, с целью упрощения технологии, повышения надежности армирования и сокращения стоимости работ, замачивание, уплотнение и армирование грунтового массива производят в одну стадию при подаче твердеющего раствора через направленный гидроразрыв, а армирование выполняют в виде системы вертикальных регулируемых плоских элементов повышенной жесткости.1. The method of preparation of the base, including the formation of wells with the installation of injectors, soaking, compacting and reinforcing the soil mass with a hardening solution through hydraulic fracturing, characterized in that, in order to simplify the technology, increase the reliability of reinforcement and reduce the cost of work, soak, compact and reinforce the soil mass produced in one stage when a hardening solution is supplied through directional fracturing, and the reinforcement is performed in the form of a system of vertical adjustable flat elements of increased stiffness. 2.
