Description

Изобретение относится к осушительным мероприятиям, выполняемым путем понижения уровня воды, преимущественно в подземных горизонтах, в частности к устройствам для откачки воды при производстве работ в строительном и горном деле.The invention relates to drainage measures carried out by lowering the water level, mainly in the underground horizons, in particular to devices for pumping water during construction and mining.

Известно устройство для забора воды из скважин, включающее наружную и внутреннюю трубы, выполненные на наружной поверхности последней спирали с размещенными между ними каналами, перекрытыми перегородками, около которых располо- ю жены окна наружной и внутренней труб и погружной насос [ 1 ].A device is known for taking water from wells, including the outer and inner pipes, made on the outer surface of the last spiral with channels between them, blocked by partitions, around which the windows of the outer and inner pipes and a submersible pump are located [1].

Известно· также устройство для откачки воды, включающее наружную трубу, соединенную с ней водоприемную часть с водосборником на конце, внутреннюю трубу с участком впускных отверстий и размещенный в последней насос с всасывающей частью [2].It is also known · a device for pumping water, including an outer pipe, a water intake part connected to it with a water collector at the end, an inner pipe with a section of inlet openings and a pump with a suction part located in the latter [2].

Недостаток указанных устройств заклю- 2С чается в том, что они не обесречивают забор и откачку йоды водоносного пласта до его подошвы, особенно маломощных и безнапорных пластов.The disadvantage of these devices is 2C that they do not spoil the intake and pumping of the iodine of the aquifer to its sole, especially low-power and pressure-free formations.

Цель изобретения — обеспечение осушения водоносного пласта до его подошвы.The purpose of the invention is the provision of drainage of an aquifer to its sole.

Указанная цель достигается тем, что в устройстве, включающем наружную трубу, соединенную с ней водоприемную часть с ₅ водосборником на конце, внутреннюю трубу с участком впускных отверстий и размещенный в последней насос с всасывающей частью, участок внутренней трубы с впускными отверстиями размещен в нижней части водосборника, а всасывающая часть насоса расположена в промежутке между впускными отверстиями и водоприемной частью наружной трубы. При этом внутренняя труба снабжена герметизирующей муфтой, охватывающей насос над его всасывающей частью.This goal is achieved by the fact that in a device including an outer pipe, a water receiving part connected to it with a ₅ water collector at the end, an inner pipe with an inlet portion and located in the last pump with a suction part, a portion of the inner pipe with inlet openings is located in the lower part of the water collector and the suction part of the pump is located in the gap between the inlets and the water intake part of the outer pipe. In this case, the inner pipe is equipped with a sealing sleeve covering the pump above its suction part.

На фиг. 1 изображен продольный разрез устройства; на фиг. 2 — вариант закрепления насоса во внутренней трубе.In FIG. 1 shows a longitudinal section of a device; in FIG. 2 - an option of fixing the pump in the inner pipe.

Устройство имеет наружную трубу 1 с водоприемной частью 2, выполненной в виде фильтра, и внутреннюю трубу 3 с участком впускных отверстий 4, выполненных в виде окон. Под водоприемной частью 2 расположен водосборник 5, а во внутренней трубе 3 — насос 6, прикрепленный к водо подъемной трубе 7 и имеющий всасывающую часть 8, которая, как и впускные отверстия 4, размещена в пределах высоты водосборника 5, и расположена над впускными отверстиями 4.The device has an outer pipe 1 with a water intake part 2 made in the form of a filter, and an inner pipe 3 with a section of inlets 4 made in the form of windows. A water collector 5 is located under the water intake part 2, and a pump 6 is mounted in the inner pipe 3 and is attached to the water lifting pipe 7 and has a suction part 8, which, like the inlet openings 4, is located within the height of the water collector 5, and is located above the inlet openings 4 .

Поступающая из водоносного пласта 9 вода через водоприемную часть 2, размещенную в пределах водоносного пласта 9, стекает в водосборник 5, из которого через впускные отверстия 4 попадает во внутреннюю трубу 3 и далее через всасывающую часть 8 поступает в насос бис помощью водоподъемной трубы 7 подается на поверхность. Поступающие с водой отдельные механические примеси при входе во внутреннюю трубу 3 осаждаются в отстойнике 10.The water coming from the aquifer 9 through the intake part 2, located within the aquifer 9, flows into the catchment 5, from which it enters the inner pipe 3 through the inlet 4 and then enters the pump through the suction part 8 through the riser 7 to surface. Separate mechanical impurities coming in with water at the entrance to the inner pipe 3 are deposited in the sump 10.

Устройство может быть выполнено с закреплением насоса 6 во внутренней трубе 3 при помощи герметизирующей пространство между насосом 6 и трубой 3 муфты 11, которая размещается над заборной частью 8 насоса 6.The device can be performed with the fixing of the pump 6 in the inner pipe 3 using a sealing space between the pump 6 and the pipe 3 of the sleeve 11, which is located above the intake part 8 of the pump 6.

Выполнение устройства с размещением впускных отверстий внутренней трубы и всасывающей части насоса в пределах высоты водосборника (причем всасывающая часть располагается над впускными отверстиями) обеспечивает бесперебойную откачку воды в том -числе и при осушении маломощных безнапорных пластов, и тем самым повышает надежность работы оснований и фундаментов сооружений.The implementation of the device with the placement of the inlet holes of the inner pipe and the suction part of the pump within the height of the catchment (and the suction part is located above the inlet openings) ensures uninterrupted pumping of water, including the drainage of low-power pressureless layers, and thereby increases the reliability of the foundations and foundations of structures .
