Connect to body；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, it can also be indirect by intermediary
It is connected, can be the connection inside two elements.For the ordinary skill in the art, on being understood with concrete condition
State the concrete meaning of term in the present invention.
As shown in figures 1 to 6, a kind of connector 15 that spiral plastic corrugated pipe ultra-deep is buried, sequentially include end circle wall 2, in
Between connect circle wall 1 and end tail circle wall 3, end circle wall 2, it is intermediate connect circle wall 1 and end tail circle wall 3 is integrally formed, axle center is at one
On straight line, end circle wall 2, intermediate connection circle wall 1 and end tail circle wall 3 surround and accommodate the channel that liquid passes through, intermediate to connect round wall 1
It is made of the outwardly projecting wave crest 4 and trough 5 of interleaved arrangement, the round wall 2 of the diameter of trough 5 and end and end tail circle wall 3
Diameter it is equal, it includes interior chip layer 6 and outer plies 7 that centre, which connects circle wall 1, embedded with snakelike between interior chip layer 6 and outer plies 7
Bearing carrier 8,8 section left end 11 of snakelike bearing carrier and right end 12 are bar shaped, are sandwiched between arch protrusion 10, left end 11,
Right end 12 and the interior chip layer 6 and outer plies 7 form the trough 5, the arch protrusion 10 and interior chip layer 6 and outer plies
7 form the wave crest 4.
In one embodiment of the invention, snakelike bearing carrier 8 uses stainless steel, in another embodiment of the invention
In, snakelike bearing carrier 8 aluminium alloy big using intensity.
In the present invention, by the way that snakelike bearing carrier 8 is arranged in connector 15, so that the bearing capacity of connector 15 is substantially
It improves, sufficiently can completely bear the weight of earthing, in the present invention, buried 15 ring of connector of spiral plastic corrugated pipe ultra-deep
Rigidity (kN/m2) " 16.
Such as Fig. 6-7, a kind of buried system of spiral plastic corrugated pipe ultra-deep, the system is by preceding spiral plastic corrugated pipe 16, spiral shell
Revolve plastic corrugated pipe ultra-deep buried connector 15 and rear screw plastic corrugated pipe 17, the buried company of spiral plastic corrugated pipe ultra-deep
15 one end of connector and preceding spiral plastic corrugated pipe 16 are tightly connected, and the other end and rear screw plastic corrugated pipe 17 are tightly connected.
In one embodiment of the invention, it is tightly connected and is connected using sealing connecting strip 13, sealing connecting strip 13 has two
It is a.When connection, trough one week of 16 outer wall of spiral plastic corrugated pipe before one in sealing connecting strip 13 is wrapped up, another packet
It wraps up in the trough of rear screw plastic corrugated pipe 17 one week, pipe is then protruded into the buried connector 15 of spiral plastic corrugated pipe ultra-deep
Interior, sealing connecting strip 13 is located at the space 14 of the formation of wave crest 4.
Sealing connecting strip 13 is elasticity made of neoprene and Styrene-Butadiene-Styrene Block Copolymer rubber
The preparation process of body, sealing connecting strip 13 can be used neoprene and Styrene-Butadiene-Styrene Block Copolymer rubber
Glue is put into extruder, squeezes out uniform fusant by extruder, forms elastomer in die cavity.
It, should when the water in pipeline passes through connector 15 after the buried system of spiral plastic corrugated pipe ultra-deep is installed and used
Elastomer absorbs water and forms the gel not soluble in water in entire water, and volume becomes larger 2-3 times, by all irregular tables of seam
Face, hole and gap are full of, while generating huge contact pressure, thoroughly prevent from leaking, even if when seam or construction joint occur
Displacement will not leak when gap being caused to exceed the elastic range of material.
The buried connector 15 of spiral plastic corrugated pipe ultra-deep of the invention is prepared by the following method step:
1. the metal object of the wide 57.5-250mm placed in rolls, thickness 0.3-1.2mm unreel.
2. metal object heats.
3. metal object crosses modeling.
4. metal object is cooling.
5. metal object is drawn.
6. the head end of metal object is cut into swallow-tail form.
7. starting molding machine, bending mechanism, is run according to the speed of 1:1.4, metal object is sent into molding machine, is passed through
Edger roll → slicking-in roller → edger roll → molding bumps roller → brake forming mechanism, adjustment second group of roller of bending, the metal after making plastic-coated
The surface of circle is smooth.
8. it is metal rolled to ensure that adjustment is bent third group roller (while toward up-regulation, circle becomes smaller, past circle of lowering becomes larger simultaneously)
At after circle diameter and technique required by it is consistent, form snakelike bearing carrier 8.
9. the snakelike bearing carrier 8 mixed up is served feeder, starting is sent into motor.Allow snakelike bearing carrier
8 run on being sent into frame, adjust the relative position spacer of feeder, it is ensured that and snakelike bearing carrier 8 is operating above smoothness,
The end of snakelike bearing carrier 8 is sent into the upper polytetrafluoro pinch roller of pressure, and adjusts roller guide assembly.And up and down poly- four
Fluorine pinch roller unclamps；Adjust the inclination angle of four-roller winding；The center line at the inclination angle at the inclination angle and roller of upper lower compression roller is protected simultaneously
It holds consistent.
10. first starting die heater, about 45 DEG C of temperature of die heater water are set；Baking oven is opened simultaneously, when snakelike bearing carrier
8 are preheated to suitable temperature (about 100 DEG C), and the first extruder of starting squeezes out interior chip, and it is (same that the second extruder of starting squeezes out outer plate
When also start hot air apparatus automatically), revolving speed is adjusted to process value, depresses upper and lower tetrafluoro pinch roller, then starting molding, bending,
It is sent into motor, is run according to corresponding ratio, while snakelike bearing carrier 8 is penetrated upper tetrafluoro pinch roller, makes snakelike carrying structure
Part 8 is then directed into lower tetrafluoro pressure roller with interior chip, outer plate synchronizing moving.Outer plate blowing device is opened, and adjusts side pressure
Wheel, it is ensured that outer plate is consistent with the shape of snakelike bearing carrier 8.
The length of manufactured product as needed is cut off up to connector of the invention.
