Description

Hole water stop device for pipe jacking engineering Technical Field The utility model relates to the technical field of hole water stop, in particular to a hole water stop device for pipe jacking engineering. Background The pipe jacking construction is to overcome the friction force between the pipe and the surrounding soil, push the pipe into the soil according to the designed gradient, transport away the earth, push the pipe into the soil continuously by the second section of pipe after the pipe is pushed into the soil layer, the principle is to push the tool pipe or the heading machine from the working pit to the receiving pit all the time through the soil layer by the thrust between the main top oil cylinder and the pipe and between the pipe and the relay, and lift the pipe immediately after the tool pipe or the heading machine, and embed the pipe between the two pits. The water body that needs to use entrance to a cave sealing device to flow out to the entrance to a cave in the push pipe engineering at the present stage is stopped water through the stagnant water pad to its inside packing looks adaptation basically to current stagnant water mode, because stagnant water pad size is comparatively fixed not suitable for all the entrance to a cave, it needs the supplementary beating just can carry out the stagnant water installation in addition, stagnant water pad has certain weight simultaneously, need great amount of labour when raising the stagnant water pad to certain altitude installation to reduce the efficiency of construction, for this reason, we propose an entrance to a cave sealing device for push pipe engineering to solve above-mentioned problem.
