Shatov S. Formation of organizational and technological decisions for clearing the debris of constructions in specific conditions

Subject of the research is technological processes of handling debris of destroyed buildings in specific conditions as well as machine complexes and their operation equipment equipped with gripping devices. The objective of the thesis is increasing efficiency of technological processes of handling debris of destroyed buildings in specific conditions on the basis of urgent analysis of their structure and determination of mechanization means corresponding to the nature of destruction. Method of research: theory of systems, theory of objects recognition - to investigate structure of debris; theory of systems of mass service, technological decisions of debris handling; Theoretical and practical results: the sequence of making organizational-technological decisions of debris handling for the shortest time possible and in terms of using rational components of mechanization means whose characteristics correspond to fractional content of construction debris has been developed; reduction of time of debris handling at 1.5-2 times. Scientific novelty: first there was developed the generalized model of making organizational-technological decisions of handling debris of constructions and its components; first on the basis of urgent analysis of destruction structure there was determined the nature of distribution of masses and sizes of debris; first there were discovered new principles of technological processes of handling debris of destroyed objects, which lie in consideration of fractional content of the debris, firstly created method of comparative analysis of object elements by their electronic fixation and processing which forms database for choosing sequence of works and mechanization means; there has been obtained further development of scheme of operation processes organization of handling debris of destroyed constructions; there has been obtained further development of basics of formation of labour bodies for mechanization means for handling debris; for bulldozers and rippers equipped with operation equipment for debris handling, first there was justified a technical index of bearing capacity. Extent of implementation: there were developed the projects of normative documentation transferred to the State Enterprise "Dniprostandartmetrologiya" (Dnipropetrovsk); there were developed and produced mechanization means of multipurpose type on the basis of excavators, loaders and bulldozers: implemented in the trust "Dneprstroymekhanizatsiya" and LLC "SPK "Trust of reconstruction and development", Dnipropetrovsk, Berdyanski plant of road machines; there was confirmed the total effect of implementation of projects and propositions was 420 thousand UAH. Sphere of implementation: accomplishment of reconstruction of destroyed and demolished constructions.
