Abstract
The article deals with the technological set of small-sized equipment for shotcrete works taking into account the influence on its operation of the coefficient of filling the volume of the concrete mixer bin. The concrete mixer in this set is accepted as the base machine. The kit consist of the dosing unit, the concrete mixer unit, the universal hose concrete pump, the hydraulic drive unit, the control panel, equipment for shotcrete works. The basis for the creation of such a kit is a structural scheme: “the dosing unit - a component weighing bin - a concrete mixer - a receiving tray - a hose concrete pump - a pipeline with a working nozzle that has a ring nozzle”. The first experience of using separate technological kits emphasized their versatility of use directly at the construction site. In this regard, it is possible to determine their use for: - transportation of wet building mixes and carrying out of the shotcrete works; - repair and reconstruction of existing buildings and structures; - concreting floors, safes; - carrying out formworkless concreting when laying monolithic reinforced concrete and the manufacture of reinforced concrete structures and products. The dependence for determining the coefficient of filling the volume of the bin of the mixer Кзо is proposed based on the peculiarities of the work of the proposed set, in which all technological operations are combined in time. At the same time, the capacity of the mixer Птехн. бзм is equal to the capacity of the universal concrete pump Птехн. бн, which is a prerequisite for the stable operation of the kit. The results of the planned experiment are presented, which is used in the research of the dependence of Кзо= f (dшл., n1, n2, R). The efficiency of operation of the offered kit with the maximum productivity at maintenance of Кзо=0,70…0,71 is justificated.
