The draining device consists of the tubes made of elastic resilient material. The tubes are combined in a common construction designed as a cylindrical tubular body with four longitudinal tubes in its walls. Two of them are connected with the sealed balloons located in sequence outside the tubular body. Two other tubes are open and perforated allowing for supplying and aspirating the fluid. The working end of the cylindrical tubular body is made open for aspirating the fluid. The opposite ends of four longitudinal tubes are equipped with the functional pipe unions.
Assembly for sealing a joint of a drainage well and a pipe, comprising a first tubular sleeve having a proximal end, a distal end, a tubular body and an outside diameter equal to the diameter of the pipe, where said sleeve comprises a material hydrophilic and a pipe covering placed inside the first tubular sleeve and extending beyond the tubular body; sealing method; sealing equipment
