Beschreibung
Zusammenfassung:	The utility model discloses an oil cylinder grouting hole packer which comprises a grouting barrel, the grouting barrel is connected with a grouting pipeline, a first one-way check valve and a second one-way check valve are sequentially arranged on the grouting pipeline, the first one-way check valve and the second one-way check valve are arranged in opposite directions, a piston oil cylinder is connected between the first one-way check valve and the second one-way check valve through a pipeline, and the piston oil cylinder is connected with the grouting barrel through a pipeline. The piston oil cylinder is connected with a pushing oil cylinder which is connected with a quick advancing and retreating connector of the multi-way reversing valve through a high-pressure oil pipe. The drilling machine pump station is used for directly providing working pressure, power comes from a working site, pressure loss is avoided, gas extraction concentration is improved, extraction purity is improved, hole sealing cost is e
