Abstract

Изобретение относитс к горному делу. Целью вл етс экономи материальных ресурсов за счет обеспечени многократного использовани устройства. На нагнетательной трубке (Т) 4 устройства установлены основной герметизатор (Г) из упругодеформируемого рукава (Р) 1 и дополнительный Г из Р 7. На торцах Р 1 имеет заделки 3 и 2, а Р 7 - заделки 9 и 8. Смежные заделки 8 и 3 Р 7 и 1 жестко скреплены между собой посредством соединительной втулки 10 с уплотнителем и установлены на Т 4 подвижно. Противоположные заделки 9 и 2 соединены с Т 4 неподвижно. Кольцевые полости 5 и 11 Р 1 и 7 обособлены друг от друга и имеют самосто тельные входы 6 и 12. Причем Р 1 и 7, установленные на Т 4, предварительно упруго сжаты в продольном направлении с возможностью увеличени диаметра и уменьшени их длины. При установке устройства в пробуренный шпур создают давление жидкости в основном Г больше не менее чем в 2 раза по сравнению с давлением в дополнительном Г. В результате происходит перемещение последнего в глубь шпура. После окончани герметизации шпура нагнетают в трещиноватые породы скрепл ющий состав. Разгерметизацию и извлечение устройства после окончани нагнетани состава производ т путем повышени давлени жидкости в обоих Г, последующего сброса давлени в основном Г и вновь повышени в нем давлени . 2 ил.The invention relates to mining. The goal is to save material resources by ensuring reuse of the device. On the delivery tube (T) 4 of the device, the main sealer (G) of the elastically deformable sleeve (P) 1 and the additional G of P 7 are installed. At the ends of P 1, they have seals 3 and 2, and P 7 - seals 9 and 8. Adjacent seals 8 and 3 P 7 and 1 are rigidly fastened to each other through a connecting sleeve 10 with a seal and mounted on T 4 movably. Opposite fittings 9 and 2 are connected to T 4 motionless. The annular cavities 5 and 11 of P 1 and 7 are separated from each other and have independent inputs 6 and 12. Moreover, P 1 and 7, mounted on T 4, are pre-elastically compressed in the longitudinal direction with the possibility of increasing the diameter and decreasing their length. When the device is installed in the drilled hole, the pressure of the fluid is generally greater than G at least 2 times as compared with the pressure in additional G. As a result, the latter moves into the depth of the hole. After the seal is completed, the bore-hole is injected into the fractured rocks by a bonding composition. The depressurization and removal of the device after the end of the injection of the composition is carried out by increasing the pressure of the liquid in both T, then relieving the pressure in the main T and again increasing the pressure in it. 2 Il.

Claims

Claim

A device for injecting fastening compounds through bore holes into fractured rocks, comprising a sealant from an elastically deformable sleeve mounted on the discharge tube with seals at the ends, forming an annular cavity around the discharge tube with an entrance to it, characterized in that, in order to save material resources by to ensure multiple use of the device, it is equipped with an additional sealant installed on the discharge tube from an elastically deformable sleeve with seals at the ends and with a connecting sleeve with a sealant, while adjacent sleeve seals are rigidly fastened together by means of a sleeve with a seal and are mounted on the discharge tube movably, and the opposing terminations are connected to the discharge tube motionlessly, wherein the annular cavity of the additional sealant is separate from the main sealant cavity and has an independent the entrance, and the sleeves installed on the discharge tube are previously elastically compressed in the longitudinal direction with the possibility of increasing diameter and reduce their length.
