Gwarancja jakości w mikrotunelowaniu

The authors of the article present the details of a "Microtunnelling" research project carried out in IKT Institute in gelsenkirschen, Germany. In order to perform the study a 1:1 scale measurement device was assembled for noting the loads on pipes and their joints, as well as ground tension stresses. The research results and analysis led to developing a number of directives concerning pipe joints optimum values for designing and monitoring microtunneling projects as well as construction site measurement and quality control.

Pipe-jacking has proven its worth as an economically rational and environmentally safe alternative to open-cut installation of new pipelines. The pipes are subjected to exceptional loadings during the installation procedure, however, particularly in case of directional (i.e., "non-straight") pipe routes and difficult soil conditions. Test and inspection concepts applied up to now have been restricted in this context to the inspection of individual pipes and joints only, ignoring the pipe-string bed and curvature. This is the background to a research project conducted by the IKT - Institute for Underground Infrastructure with financial support from the Ministry of the Environment of the German state of North Rhine-Westphalia and the Emschergenossenschaft. A test system, using which jacking loads exerted on pipes and pipe joints, including the resultant bed stresses, can be simulated on a 1:1 scale, has been developed.
