Известно устройство дл инъекции ан- тифильтрационного материала в водопрсн. ницаемые грунты, содержащие стержень со сквозными каналами, верхний конецA device for the injection of antifiltration material into water is known. pinched soils containing rod with through channels, upper end
которого снабжен непроницаемым щитком 1. Недостатками этого устройства вл ютс ограниченность .глубины его погружени в грунт-и невозможность его использовани дл уплотнени ({жльтрую- щих скальных и бетонных массивов.which is equipped with an impermeable flap 1. The disadvantages of this device are the limited depth of its immersion in the soil — and the impossibility of its use for compaction ({zhltyuyushchy rock and concrete massifs.
Наиболее близким к предлагаемому вл етс устройство дл нагнетани раствора в скважину, содержащее наружную трубу и выступающую своими концами за ее пределы внутреннюю трубу с раз щим- ными кольцами на нижнем конце и приспособлением дл осевого обжати колец на верхнем конце 2. Недсх:татком ато- гр устройства вл етс невозможностьClosest to the present invention, there is a device for injecting a solution into a well, containing an outer tube and an inner tube protruding beyond its limits, with a split ring at the lower end and a device for axial reduction of the rings at the upper end of 2. Nedsh: c device is the impossibility
{утшотнени стенок скважины по всей ее длине.{sostennya walls of the well along its entire length.
Целью изобретени вл етс уплотн кие стенок скважины по всей ее длине.The aim of the invention is to seal the walls of the well over its entire length.
Это достигаетс тем, что устройство снабжено смонтированной на наружной трубе прижимной плитой с прокладкой, а в стенках обеих труб за разжимными колцами образованы соосные отверсти . Устройство представле 1О на чертеже. Устройство содержит наружную трубу 1 и установленную в ней и выступающую своими концами за ее пределы внутреннюю трубу 2. На нижнем конце внутренней трубы установлены разжимные колы ца 3 с упорными муфтами 4. В стенках труб 1 и 2 выще разжимных колец выполнены два р да сосх;ных отверстий 5 дл выхода раствора в скважину 6, На верхнем конце внутренней трубы установлено приспособление дл осевого обжат разжимных колец 3 в скважине, состо щее из гайки-штурвала 7. На наружной трубе в устьевой части скважшш установлена прижимна металлическа плита 8This is achieved by the fact that the device is equipped with a pressure plate with a gasket mounted on the outer tube, and coaxial holes are formed in the walls of both pipes behind the expanding rings. The device is 1O in the drawing. The device contains an outer pipe 1 and an inner pipe 2 which is projected at its ends and extends beyond its limits. At the lower end of the inner pipe, expansion rings 3 are installed with stop sleeves 4. In the walls of pipes 1 and 2 above the expansion rings there are two rows of cylinders; 5 holes for release of the solution into the well 6. A fixture for axially crimped expansion rings 3 in the well is installed at the upper end of the inner pipe, consisting of a nut-wheel 7. A pressure metal plate is installed on the outer pipe in the mouth of the well. litas 8
