Petrovskiy A. Use technology of bentonites produced in Ukraine under no-dig laying of engineering communications

Object - technologies of a laying of engineering communications; the purpose - development of technology of use Ukrainian bentonites at under no-dig laying of communications a method of horizontally directed boring; methods - optimum mapping out of researches of technological properties, methods of mathematical statistics for processing results; results - are established laws of change of technological properties of special solutions at use Ukrainian both French bentonites and their mixes; novelty - mathematical dependences of technological properties of argillous solutions on the basis of Ukrainian bentonites from a sort and quantity of applied chemical additives are received, sizes of changes of technological parameters under no-dig layings of communications are revealed by method HDB which corrections are a subject at use Ukrainian bentonites; introduction - approbation of results of researches on an experimental lot is executed, at under no-dig laying of pipelines in a Kiev; use - at a laying of engineering communications a method of horizontally directed boring with use Ukrainian bentonites.
