Description
Technical field
The present invention relates to a kind of pipe jacking tunnel heads to stop husky antipriming into hole, especially a kind of to prevent Wai Shui, Sha
For development machine into during hole, the gap between development machine and hole circle pours in the device in received well.
Background technique
The Oujiang River (one of strong tide area, China) tidal range is big, and push pipe is mud silty sand ground soil into hole soil layer, and soil layer contains height
Artesian water, simultaneously because push pipe well is formed by stretching steel sheet pile enclosure, and leak is serious；Push pipe exists very into hole with this condition
Big construction risk is also very high to construction management and technical requirements.Therefore, it is necessary to design a kind of pipe jacking tunnel head to stop into hole
Husky antipriming.
Summary of the invention
The present invention is to provide for a kind of pipe jacking tunnel head and stops husky antipriming into hole, for preventing Wai Shui, husky tunneling
Into during hole, the gap between development machine and hole circle pours in received well machine.
To solve the above problems, the technical scheme is that a kind of pipe jacking tunnel head stops husky antipriming, tool into hole
There is a wall bushing, the wall bushing inner wall welds a ring shape iron plate, annular is arranged on the annular iron plate front end face
Cord rubber slab can reinforce the sealing performance of annular iron plate Yu development machine shell, effectively water, sand boil be prevented to enter received well；Institute
Annular iron plate rear end face installation rubber moccasin pipe or air bag are stated, supporting role when for the deformation of annular iron plate can be in annular iron
Piece holds out against iron plate when being pressurized, and makes the better tightness of annular iron plate, cord rubber slab and development machine shell.
Further, the annular iron plate has certain bending property, when push pipe head passes through annular iron plate, annular iron
Piece is closely attached to development machine outer wall after being squeezed by development machine, play the role of water blocking, sand.
Further, the wall bushing is made of steel plate, and the annular iron plate is welded on wall bushing center.
Further, the annular iron plate internal diameter is slightly less than push-bench shell；The annular cord rubber slab internal diameter is slightly less than
Annular iron plate internal diameter.
Further, it is equipped with positioning plate behind the rubber moccasin pipe or air bag, positioning plate is welded on wall bushing, passes through
Positioning plate plays the role of positioning, it can be ensured that when push-bench is into hole, annular iron plate, cord rubber slab, rubber moccasin pipe or air bag it is steady
It is qualitative.
Further, fixed plate is welded with behind the positioning plate, fixed plate is using set square and positioning plate composition positioning knot
Structure, and be welded on wall bushing, the stability of antipriming described in set square and wall bushing, positioning plate link enhancement.
The beneficial effects of the present invention are:
Pipe jacking tunnel head of the invention stops husky antipriming into hole, when can solve push pipe or shield, prevent outer water,
During development machine is into hole, the gap between development machine and hole circle pours in received well sand.
Detailed description of the invention
Fig. 1, which is pipe jacking tunnel head of the invention, stops husky antipriming structural schematic diagram into hole；
Fig. 2 is that the pipe jacking tunnel head of invention stops husky antipriming operation schematic diagram into hole.
Specific embodiment
The present invention is further illustrated with embodiment with reference to the accompanying drawing.
As shown in figures 1 and 2, pipe jacking tunnel head of the invention stops husky antipriming into hole, by wall bushing 1, annular iron plate
2, cord rubber slab 3, rubber moccasin pipe or air bag 4, positioning plate 5 form.Wall bushing 1 is made of steel plate, in wall bushing 1
One ring shape iron plate 2 of center weld, annular iron plate 2 have certain bending property, and internal diameter is slightly less than push-bench shell, annular iron
Annular cord rubber slab 3 is installed simultaneously before piece 2, annular 3 internal diameter of cord rubber slab is slightly less than annular 2 internal diameter of iron plate, and the two is being pushed up
It is closely attached on development machine outer wall 7 after being squeezed when pipe is into hole by development machine, plays the role of water blocking, sand block；Rubber is installed after annular iron plate 2
Glue moccasin pipe or air bag 4 play supporting role when annular iron plate 2 deforms, can hold out against annular iron plate 2 when annular iron plate 2 is pressurized,
Make the better tightness of annular iron plate 2, annular cord rubber slab 3 and push-bench shell；It is fixed to weld after rubber moccasin pipe or air bag 4
Position plate 5 play the role of positioning, positioning plate 5 is welded on wall bushing 1, is played the role of positioning by positioning plate 5, it can be ensured that push-bench into
When hole, the stability of annular iron plate 2, cord rubber slab 3, rubber moccasin pipe or air bag 4；Water burst occurs suddenly when if push pipe is into hole
Gush sand；The device can live husky, water blocking, it is ensured that safety of the push pipe into hole.
Fixed plate 6 is welded with behind positioning plate 5, fixed plate 6 forms location structure using set square and positioning plate 5, and welds
It connects on wall bushing 1, the stability of antipriming described in set square and wall bushing 1,5 link enhancement of positioning plate.
Application implementation example of the present invention
Engineering is Wenzhou City's Sewage Treatment Plant river pipe river improvement project, and received well is leaked in the borehole wall by Larsen steel sheet pile enclosure
Water spot is more, and hole nearby has water burst to gush husky phenomenon, and hole water pressure is very big.Therefore, using a kind of pipe jacking tunnel head
Stop husky antipriming into hole, as shown in Fig. 2, antipriming keeps tightly being close to push pipe head, reaches when push-bench is into hole
Hole hermetic seal stops husky effect.
The above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be to the present invention
Embodiment restriction.For those of ordinary skill in the art, it can also make on the basis of the above description
The variation of other shapes and size.There is no necessity and possibility to exhaust all the enbodiments.
