FILTRATION DEVICE FOR PROVISIONAL SANITATION INSTALLATION ON A CIVIL ENGINEERING WORK, CAISSON AND PROVISIONAL SANITATION METHOD RELATING THERETO

摘要

The invention aims to provide, at a lower cost, a filtering device providing an effective and lasting temporary remediation solution throughout the duration of a civil engineering project. To do this, the filtration device (1) according to the invention comprises: - a filter material, - a box (5) having a bottom (6) and upstream walls (7) and downstream (8) defining a volume of receiving (15) for the filter material (16), each of the upstream (7) and downstream (8) walls including at least one perforated portion (23) so as to allow the flow of runoff water through said upstream walls ( 7) and downstream (8), this box having a weight of less than 350 kg. The subject of the invention is also the caisson and a temporary cleaning method implementing the device.
