Sealing device is received to balanced pipe pushing jack of varus muddy water of stagnant water rubber slab

The utility model provides a sealing device is received to balanced pipe pushing jack of varus muddy water of stagnant water rubber slab, the device includes tube coupling, stagnant water rubber slab enstrophe mechanism, the tube coupling is the cylinder tubular structure, on the disc, the pipe pushing jack gets into from the one end of tube coupling stagnant water rubber slab enstrophe mechanism suit outside the cylinder of tube coupling, the drill way pipe is installed on the side of tube coupling anterior segment, the rubber division board is fixed at the drill way pipe diameter to in opening some fixed slots to in the rubber division board inserted the tube coupling, the rubber division board is radially to be arranged, the length that the rubber division board inserted in the tube coupling is greater than the distance of waiting to install pipeline section and drill way inside pipe wall. Steel sleeve is U -shaped trough - shaped structure, steel sleeve's one end and drill way sealing of tube. The device improves sealing effect greatly, and automatic level is higher, and is controllable to the stagnant water.
