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.

Highlights

Up-to-date construction assumes various types of equipment which are used as separate machines [1 – 5] when performing concrete works

A rational solution in the performance of concrete work in the construction site [6] is the use of certain types of equipment in both technological complexes and technological kits

Summary

Introduction

Up-to-date construction assumes various types of equipment which are used as separate machines [1 – 5] when performing concrete works. Considering the concreting processes under such conditions [7, 8], a new universal small-based equipment, which is patented in Ukraine [9], attracts attention and passed approbation at many construction sites when performing works by the wet concrete spraying method. New small-based equipment that works in the conditions of technological complexes or kits includes the following: - concrete mixers operating in a cascade mode (trivalent and gravity-forced action); - mortar-concrete pumps (with ball and poppet valves); - concrete pumps (universal non-piston hose); - robotic nozzles for concrete spraying method with a ring nozzle. Each of the modules is characterized by separate capabilities that are used in specific construction conditions [11] The use of such modular kits for the manufacture of reinforced concrete structures and products in the construction site using the method of off-shuttering concreting is of particular use. Basic concrete pump with hydraulic drive, in comparison with two-piston concrete pumps, has a number of advantages: minimum weight with a wide range of performance, reliability of construction and improved operating conditions due to the improvement of its design in comparison with existing hose concrete pumps, economic energy consumption
