n the densely populated city of Gagny, just outside Paris, a large water collector was built by the use of microtunneling. This basin will serve as a rain collector, avoiding floodings in the event of heavy and long rain periods.
Remarkable for this project is the tight curve radius in combination with a common pipe length of 3.00 m. Thanks to the largest model of the Hydraulic Joint (JC260), no significant sacrifice had to be made on pipe lengths which was beneficial for the efficiency of the entire project. Furthermore, precise monitoring of the joint openings in MSS makes it possible to realize this kind of curved microtunneling in an effective and reliable way. Not to be underestimated was the extremely compact construction site in this urban area, which involved an extra complex logistic-exercise that, partly due to the real-time status of the construction site in the MSS-cloud service, was executed even more organized.
