Abstract: A filtering structure intended to be incorporated a vertical swimming pool wall has a filtering device and a pumping device with the pumping device having an electrical part, including an electric motor, and a hydraulic part equipped with a turbine. The filtering structure has a suction port facing towards a nominally horizontal access passageway partly submerged in water, and emerging towards a nominally vertical tank arranged thereunder. The filtering structure has a tank communicating with a nominally vertical column, partly in the upper part of which is arranged the hydraulic part. The electrical part is arranged above the level of the water to be treated and is contained in the nominally horizontal access passageway, while the hydraulic part is immersed in a volume of filtered water.

Abstract: A reinforcement pillar for propping a structure with vertical walls, which includes an envelope with a cylindrical shape, formed from a flat flexible panel with a rectangular shape, including apertures in the vertical walls for securing to the vertical walls, the vertical free edges of the flexible panel being designed to be secured to one another and folded into a cylindrical shape and secured to one another, the envelope being retained relative to the wall by a split hollow tube which stabilizes the envelope
