FIELD: construction.SUBSTANCE: device comprises a sharp tip, a filter water receiving pipe, a string of water-lifting pipes, a weight for applying impact loads at a string of filling water-lifting pipes and an element to perceive impact loads. The element is arranged in the form of an adapter in a filling column with a threaded connection of neighbouring pipes. The water-intake well is equipped with a water-jet pump. The inner volume of the water-receiving filtering string is separated from the inner volume of the water-lifting pipe with a rigid water impermeable partition, where a mixing chamber of the water jet pump is arranged.EFFECT: invention provides for depth of filling of a tubular well for several dozens of metres, water lifting from depth of several dozens of metres.2 dwg |
