More Information
Summary:The invention relates to the field of sewage filtering, in particular to a foundation pit drainage filtering device for building construction, which comprises a flow guide pipe, a plurality of filtering plates and a plurality of collecting barrels. Impurities in the sewage gradually block filtering holes in the filtering plate, the impact force of water flow acting on the filtering plate is larger than that of the collecting barrel, the filtering plate slides downwards along the flow guide pipe, the first water inlet and the second water inlet in the side wall of the collecting barrel are opened, and the sewage carrying the impurities directly enters the collecting barrel through the first water inlet and the second water inlet; and the through holes in the collecting barrel are blocked by impurities from the inner side to the outer side. In the process that the filter plate slides downwards, the collecting barrel extends, the pressure in the collecting barrel is reduced, water flow enters the collecting barr
