Increasing the reliability of engineering buildings and strengths of use of new small-based equipment for concrete works

Abstract

The article considers the possibility to increase the reliability of engineering buildings and facilities due to the use of new small-based equipment both in the operating conditions of technological complexes and in the conditions of technological sets. An example of the use of a technological complex with a universal hose concrete pump for strengthening the supporting columns of a medical centre being built by the wet concrete spraying method is given. The structural scheme of energy consumption by technological sets of small-based equipment is given. The variants of using the technological set of small-sized equipment for concrete work in various ways. One of the universal technological kits of effective small-based equipment is shown. As part of the proposed kit, the base machine can successfully be used universal non-piston hose concrete pump. Dependencies for determining the productivity of a hose concrete pump and the cost of its power for transporting a concrete mixture are proposed.
