Description
Technical field
The present invention relates to pipe-line construction corrugated pipe field, and in particular to a kind of small-sized polyethylene helical bellows connect
Mouthful.
Background technology
Polyethylene helical bellows are the newest overall plastic winding pipe developed in the market.The tubing is gathered with high density
Ethene (HDPE) is raw material, and tubing has big external surface area, forms the same resistance to compression of pipeclay.The tubing welding effect is good, enhancing seam
Tensile strength.It is additionally arranged internal rib formations, is advantageous to improve the stability of ring stiffness.Existing each size pipe DN200~
2000mm, pipe length are 6 meters, 9 meters, 12 meters.
The anti-weight bearing power of polyethylene helical bellows：Polyethylene helical bellows have larger specific surface area, expand
Contact surface with soil, uniformly by external force, the backfill inserted in pipeline trough and pipeline are born tube surfaces jointly in itself
The pressure of Soil Surrounding, pipeclay collective effect is formed, external loads can thoroughly be decomposed rapidly and be delivered to whole piece pipeline
In, reduce external loads to greatest extent influences on the impact of pipeline itself.
The ability of the anti-ductile failure of polyethylene helical bellows：There is upright internal-rib among polyethylene helical bellows ripple,
And internal-rib and ripple are continuous winding whole piece pipelines, and structural stability, the stability of ring stiffness of crest can be greatly improved
With the creep resistance of tubing, toughness is greatly improved, and has the ability of excellent anti-ductile failure, resistance to slow crack growth
It can significantly improve.
Polyethylene helical bellows tensile strength：The outer wall construction of polyethylene helical bellows is higher than Hollow wall tube by 40%,
Therefore the bonding plane of the hollow band of internal-rib of polyethylene helical bellows is generouser, considerably increases the tensile strength of seam, so as to
So that tubing has more excellent anti-lateral pull.
Polyethylene helical bellows may be used on：1) industry such as seawater, industry, chemical plant, Medicine Factory arranges corrosive dirt
Waterpipe；2) reconstruction of the old city town, the dirty shunting engineering of rain, sewage treatment plant, destructor plant draining；3) municipal administration, architectural engineering are buried
The heavy constructions such as draining, power plant；4) irrigation and water conservancy irrigation, water drainage etc..
Existing polyethylene helical bellows use spigot-and-socket electric melting connection, and bellmouth with socket is added using real wall PE pipes
Work is formed, and its precision is very high, and electric network is arranged in socket, after socket inserts bellmouth, passes through electric current socket and bellmouth
Surface PE material moltens reach sealing effectiveness together, whole fusion process is controlled using special equipment by temperature and time
Reliably realize, such connected mode not only inherently reduces the possibility of seepage, while ensure that the intensity of interface
With improve lateral pull intensity.
But it is that heating wire is rolled into M shape bandings in the prior art, then carries out electricity on bellmouth inwall with sesame nail nail
It is molten, nailed on after being due to heating wire, be inconvenient to dock in socket joint, easily caused during insertion and come off, and heating wire
Face of weld can not abut between space distance causes greatly very much pipe.
The content of the invention

In art be due to heating wire after nail on, be inconvenient to dock in socket joint, easily cause during insertion and come off, and heating wire
Space distance cause very much the problem of face of weld can not abut between pipe greatly.
The technical proposal of the invention is realized in this way：A kind of small-sized polyethylene helical bellows welding junction, including position
Socket section and faucet section in polyethylene helical bellows both ends, the socket section end set annular table, annular table endpiece
Cladding section is wholely set, the cladding section inwall is provided with the wave copper cash being evenly arranged along inwall, and the wave copper cash is embedding
The maximum distance dimension for entering to coat section inwall and spilling partial distance cladding section inwall is 1mm~3mm, the cladding Duan Shangshe
Put some exhaust holes being evenly arranged；
The faucet section termination sets the anchor ring parallel with annular table inwall.
Further, the quantity of the exhaust hole is six and is mutually 60 ° and is uniformly arranged.
Further, the faucet section outer wall is wholely set limited location circle.
Further, the spacing collar and the distance of anchor ring termination and the distance phase of cladding section inwall and annular table inwall
Deng.
Further, any one described exhaust hole edge sets wire guide, the adjacent exhaust aperture and wire guide
Interior setting copper cash binding post, the copper cash binding post electrically connect with wave copper cash.
By above disclosure, beneficial effects of the present invention are：The invention provides a kind of small-sized polyethylene helical ripple
Line pipe welding junction, due to copper cash be embedded in cladding section inwall, its spill partial distance cladding section inwall maximum distance dimension be
1mm~3mm, such design is far superior in the prior art by electric heating adjusting screw in Nei Bi, when socket section and faucet section are docked,
Do not influence to dock effect, convenient docking, cannot be easily caused during insertion and come off, while copper cash is set in inwall in wave, is increased
The welding area of copper cash and faucet section, makes to be fused together that to reach sealing effectiveness more preferable when carrying out electric melting connection.
