Zusammenfassung: | The invention discloses a jacking sleeve for tunnel guide pipe construction and a jacking device for tunnel construction, and particularly relates to the technical field of tunnel construction.The jacking sleeve is provided with a pressure assembly, a first guide pipe, a second guide pipe, a filtering device and a dust collection ring, so that the dust collection ring can extract smoke dust and impurities generated in the punching process when a drill rod is in contact with a rock stratum and conducts punching, and the drilling efficiency is improved; meanwhile, due to the fact that gas exhausted by a second guide pipe can enter the telescopic pipes on the upper portion and the lower portion along the second guide pipe, the telescopic pipes push the dust collection rings to be in an attached state with the rock stratum all the time, and the dust collection efficiency is improved. The dust collection effect is prevented from being affected by position deviation of the dust collection ring in the construction p |
