Description

Изобретение отноеите к строительству зданий и сооружений на грунтах с высоким уровнем грунтовых вод, в частности к устройствам дл водопонижени .The invention is pending to the construction of buildings and structures on soils with a high level of groundwater, in particular to devices for dewatering.
Известны водопонизительные скважины, включающие иглофильтр, надфильтровые трубы и обсыпку иглофильтра из дренирующего материала 1.Known water wells, including the needle filter, superfilter pipes and sprinkling the needle filter of the draining material 1.
Известна также водопонизительна скважина , включаюи1а перфорированную трубу с фильтрующей обсыпкой и герметизирующий устье затвор 2.A well-known water-well is also known; it includes a perforated filter-sprinkled pipe and a shutter 2 that seals the mouth.
Недостаток указанных устройств заключаетс в том, что они не приспособлены дл откачки воды с разных горизонтов в предev ax фильтрующей части скважины, а это п-риводит к необходимости применени р да скважин с различной глубиной расположени их фильтрующей части и к значитель-, ным затратам на бурение дополнительных скважин и их эксплуатационное обслуживание . Кроме того, при выполнении водопонижени в услови х, стесненных строительными работами, устройство дополнительных скважин невозможно.The disadvantage of these devices is that they are not suitable for pumping water from different horizons in the forehead of the filtering part of the well, and this necessitates the use of a number of wells with different depths of their filtering part and significant costs for drilling additional wells and their maintenance. In addition, when performing water lowering in conditions constrained by construction work, the installation of additional wells is impossible.
Цель изобретени - - обеспечение откачки воды с раз1п 1х уровней.The purpose of the invention is to provide for pumping water from 1 x 1x levels.
Это достигаетс тем, что скважина, включающа перфорированную трубу с фильтрующей обсыпкой и герметизирующий устье затвор , снабжена водоводом и размепгенными в перфорированной трубе штоком и закрепленными на нем с зазором порпш мп. а фп.ьтрующа обсыпка выполнена с раз:1ел ю1цмми ее по высоте уплотпительнымп прослойками , рассто ние между которыми соответствует зазору между поршн ми, причем ьер.хний порщень имеет отверстие, к которому присоединен водовод.This is achieved by the fact that the well, which includes a perforated pipe with filtering sprinkles and a sealing mouth, is provided with a conduit and a rod dispersed in the perforated pipe and fixed on it with a gap of pistons. The fillet spraying is made from the times: 1 its height by the sealing layers, the distance between which corresponds to the gap between the pistons, and the outer wall has an opening to which the water conduit is attached.
Такое выполнение скважины позво; :;.. осуществл ть перестановку поршней по -. соте ее фильтрующей части в места с НиИбольщим притоком воды и тем самым ускор ет процесс подготовки территории к возведению на ней зданий и сооружений.This implementation wells allowed; :; .. perform a piston permutation at -. A cell of its filtering part to places with a large influx of water and thus accelerates the process of preparing the territory for the erection of buildings and structures on it.
На чертеже показана водопонизительна скважина, общий вид.The drawing shows a water low well, general view.
Скважина содержит металлическую трубу 1 с перфорацией 2, внутри которой имеютс два поршн 3, 4, закрепленные на щтоке 5. Нижний поршень 3 глухой, верхнийThe well contains a metal pipe 1 with perforation 2, inside of which there are two pistons 3, 4 fixed on the rod 5. The lower piston 3 is blind, the upper
