(54) ИНЪЕКТОР(54) INJECTOR

II

Изобретение относитс к оборудованию дл проходки подземных выработок с укреп-. лением породы путем введени в нее с помощью инъекторов скрепл ющих растворов.The invention relates to equipment for excavating underground workings with fortified. the formation of rock by introducing into it with the help of injectors fastening solutions.

Известна конструкци инъектора, включающа трубчатый корпус с соплами внут.- ри, аэрозольный смеситель, состо щий из отсеков со сплошными поперечными и продольными отверсти ми перегородками и наконечник 1.The known design of the injector includes a tubular body with nozzles inside, an aerosol mixer consisting of compartments with continuous transverse and longitudinal baffles, and a tip 1.

Недостаток такого инъектора заключаетс в том, что в случае использовани дл укреплени пород кровли и боков выработки он не может предотвратить их обрушени , так как не рассчитан на выполнение грузонесущей функции.The disadvantage of such an injector is that, in the case of using roofing for reinforcement of the roofs and lateral production, it cannot prevent their collapse, since it is not designed to perform the load-carrying function.

Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс инъектор, включающий трубу, разжимной та.мпон, размещенный между двум фланцами, один из которых установлен на конце трубы, прижимной патрубок, выступающий из скважины, и гайку 2.The closest to the invention to the technical essence and the achieved result is an injector including a pipe, an expanding pipe located between two flanges, one of which is installed at the end of the pipe, a pressure nozzle protruding from the well, and a nut 2.

Однако недостатком такого инъектора вл етс также невозможность его использовани в цел х предотвращени обрушени However, the disadvantage of such an injector is also the impossibility of its use for the purpose of preventing collapse.

пород, в которые производ т нагнетание скрепл ющего раствора.rocks in which the bonding solution is pumped.

Цель изобретени - расширение технологических возможностей инъектора путем придани ему дополнительно грузонесущей функции.The purpose of the invention is to expand the technological capabilities of the injector by giving it an additional load carrying function.

Поставленна цель достигаетс тем, что концевой фланец инъектора выполнен в виде многолопастного кор , а прижимной патрубок , .снабжен подкладкой с дополнительной гайкой, которые устновлеиы на его выступающем конце.The goal is achieved by the fact that the end flange of the injector is made in the form of a multi-blade core, and the clamping nozzle, is equipped with a lining with an additional nut, which are installed at its protruding end.

На чертеже изображен предлагаемый инъектор.The drawing shows the proposed injector.

Инъектор состой, из трубы I, конец которой снабжен фланцем 2, выполненным в виде миоголопастного кор . На трубе свободно насажен разжимной тампон 3, другой фланец 4, прижимной патрубок 5 с подкладкой 6 и дополнительной гайкой 7. Выступающий конец трубы снабжен гайкой 8. Позицией 9 на чертеже обозначена скважина.The injector is free-standing, from pipe I, the end of which is provided with a flange 2, made in the form of a myogolic core. A loose swab 3, another flange 4, a pressure fitting 5 with a lining 6 and an additional nut 7 is loosely mounted on the pipe. The protruding end of the pipe is equipped with a nut 8. The position 9 on the drawing denotes a well.

Инъектор работает следующим образом,The injector works as follows

Claims

An injector is inserted into the borehole 9 and by screwing the nut 8 a force is transmitted to the end flange 2 through the clamping nozzle 5, the flange 4 and the expanding tampon 3, while the blades of the flange core 2 are pushed into the walls of the well 9. The nut 8 is screwed down to the stop. Nut 7 and lining b at the beginning of the installation of the injector is placed closer to the end of the clamping nozzle 5 After the blades of the end flange 2 are open and the nut 8 is clamped against the stop, an additional nut 7 is clamped, which presses lining 6 to the wellhead 9, and thus The pipe I is tensioned through the protruding end of the clamping nozzle 5 and the nut 8. From this moment on, the ejector becomes a load-carrying element and it is ready to produce bonding mortar injection and a broken zone of the rock mass. Injection at the same time is conducted also, as well as injectors of the known designs. The removal of the injector is carried out after the injection process is completed before the solution begins to set in the well. To do this, unscrew the nut 8, blow the upper part of the pipe t to loosen the spreading of the blades of the flange 2 and the expanding tampon 3. Remove the pressure fitting 5 with the nut 7, the lining 6, the flange 4. Screw the nut 8 and pull out the pipe 1 with the expansion swab 3 and the end flange 2. The proposed design of the injector expands its technological capabilities and makes it possible to use it without additional temporary supports, as a result, labor costs for the production of combined supports are reduced due to the refusal of drilling holes for anchors (where nstruktivnym reasons of anchors are needed, they can be installed in the well after extraction inektsioiiye injectors). The invention includes an injector including a pipe, an expansion swab placed between two flanges, one of which is installed at the end of the tube, a pressure nozzle protruding from the well, and a nut; characterized in that, in order to expand the technological capabilities of the injector by giving it an additional load carrying function, the end flange of the injector is made in the form of a multi-blade core, and the clamping nozzle is provided with a lining with an additional nut, which are mounted on its protruding end.
