Klimenko G. Labour safety improving under engineering networks reconstruction in the constrained conditions

Subject of inquiry is the process that influence on safety of works during engineering networks reconstruction in the constrained condition. Thesis objective labour safety improving during engineering networks reconstruction with an account of the constrained conditions at the construction site. Research methods: statistical method of treatment of information and analysis of traumatism; analytical generalization of the known scientificand technical results; analysis of literary sources; method of mathematical design at the stowage of classification of schemes of excavation, installation and dismantling works under the reconstruction of engineering networks in the usual and the constrained conditions, that allowed to analyse them from the point of view of safe implementation of works; method of expert estimations; crosscorrelation ? regressive analysis; methods of theory of authenticity and mathematical statistics are at the ground of criterion of safe work scope, cost coefficient per unit which guarantees the labour safety and index which shows the influence of the analyzed factors on the security of the production process; methods ofestimation of economic efficiency are from introduction of improved engineering solution. Theoretical and practical results: ? the patents of Ukraine: inventory fencing of construction site, inventory fixing of the trench walls and equipment for pipelines installation and dismantling have been received; the Guidelines "For safe works when water supply networks are reconstructed in the constrained conditions of urban development and on the territory of the industrial enterprises" have been developed; the Routing "For installation, motion and pulling out from the trench the inventory fixing of the trench walls" has been developed. Novelty of the research: ? the classification of schemes of excavation, installation and dismantling works under the reconstruction of engineering networks in the usual and the constrained conditions; the criterion of work scope and the cost coefficient per unit which guarantees the labour safety under engineering networks reconstruction in the constrained conditions; the basic group of factors which has the influence on labour safety under engineering networks reconstruction in the constrained conditions is identified and it is regulated according to their influence on safety of the production process, in general in these groups and within each group. It has justified the index which shows the influence of the analyzed factors on the security of the production process; the engineering solutions for improving the labour safety and working conditions under engineering networks reconstruction have been implemented, namely: inventory fencing of construction site, inventory fixing of the trench walls, equipment for pipelines installation and dismantling, which are made for reducing the danger levels and for promoting the labour productivity in the constrained conditions of urban development and on the territory of the industrial enterprises.Implementation extent: "Inventory fencing of construction site" has been implemented in the building organization projects of the LTD "Fundamentstroymax" and it has been used under the engineering networks reconstruction "Equipment for pipelines dismantling" in "Barycenter". Range of application: construction and assembly works during engineering networks reconstruction.
