Njengoba sonke sazi, amapayipi e-PVC nokufakwa kwamapayipi ebusika ekushiseni okuphansi kuzoba buthakathaka ngenxa yezici zemvelo zepulasitiki, okulula ukukhiqiza umphumela wokushaya amagoli. Ngakho-ke, kufanele siqaphele kabanzi mayelana nemvelo yokwakha kanye nokuphathwa kwamapayipi nokufakwa. Eqinisweni, ehlobo elishisayo, izinga lokushisa liphezulu kakhulu ngaphansi kwemvelo yokufaka nokwakhiwa futhi kudingeka ukunaka okwengeziwe. Ngokushisa okwandayo ehlobo, uma ukusebenza kungalungile, kulula ukubangela ukuguqulwa kwepayipi le-PVC ngisho nokuphula ipayipi ngesikhathi sokuhlolwa kwengcindezi.

wax we- yepayipi le-PVC

Kubhekiselwa kolunye ulwazi oluku-inthanethi, izinyathelo zokuphepha zokwakhiwa kwamapayipi e-PVC ehlobo zichazwa kanje:
1. Ukugcinwa
kwamapayipi (1) Lapho ugcina amapayipi ehlobo, ukuphakama kwamapayipi akufanele kudlule i-1.5m, ukuphakama kakhulu kuzoholela ekuhlanganyeleni. extrusion deformation of amapayipi.
(2) Uma ukwakhiwa kungenziwanga isikhathi esifushane, inetha le-shading lizosetshenziselwa ukumboza umzimba wepayipi ngesikhathi ukuze kuvinjelwe ukuguga komzimba wepayipi okubangelwa ukukhanya kwelanga isikhathi eside.
2. Ukuxhumana kwamapayipi
(1) Ukwakhiwa kwepayipi le-PVC elinamathelayo le-TS ehlobo: qaphela ngokukhethekile inani lokunamathela. Ngokobubanzi obuhlukile bephayiphi obuvamile, inani lengcina edingekayo nalo lihlukile, njengobubanzi bepayipi elivamile Φ Lapho ububanzi bepayipi bungaphansi kuka-63mm, inani elinamathelayo lokunamathela liphakathi kuka-0.8g no-5.6g Φ 75mm— Φ 110mm kububanzi obungu-9.0g-18g Φ 140mm— Φ 160mm iphakathi kuka-27g no-35g Φ Kungu-51g-396g ngaphezu kuka-200 mm, futhi okunamathelayo kushabalala ngokushesha ehlobo. Kufanele ifakwe ngokushesha ngemva kokumbozwa, futhi ingahanjiswa kuphela ngemva kwemizuzu engama-30. ekuxhumekeni kwepayipi le-TS, i-joint yokunweba noma i-looper kufanele yengezwe njalo ngamamitha angu-50.
(2) Ukunakwa okukhethekile kufanele kukhokhwe ekugcinweni nasekusetshenzisweni kwe-adhesive:

A. ngemva kokusetshenziswa kwe-adhesive, umlomo webhodlela kufanele uqiniswe ukuze uvimbele ukuhwamuka kwe-adhesive ekuthinteni umphumela wokusetshenziswa;

B. Uma ukwakhiwa kwenziwa endaweni enomoya omubi, kuyadingeka ukugqoka imaski nezinye izinto zokuzivikela;

C. Uma iglue ifafaza emehlweni, hlambulula ngamanzi ngesikhathi.
(3) Ukwakhiwa komkhono we-PVC oguquguqukayo ehlobo: ngenxa yokuthi ipayipi le-PVC linezici zokunwetshwa okushisayo nokufinyela okubandayo, kufanele kube negebe elithile ekuxhumekeni komkhono we-PVC oguquguqukayo ( Φ Cishe u-10 mm ngaphansi kuka-63 mm Φ 75mm- Φ Cishe u-15 mm phakathi kuka-110 mm Φ 140mm- Φ Cishe u-20 mm phakathi kuka-160 mm Φ Cishe u-25 mm ngaphezu kuka-200 mm).
(4) Kunezilwane eziningi ezincane ehlobo. Lapho ipayipi lifakiwe, ukunakwa okukhethekile kufanele kukhokhwe ekumbozweni kwe-orifice yepayipi ukuvimbela izilwane ezincane ukuthi zingangeni epayipini futhi kuthinte umfutho wepayipi kanye nokunikezwa kwamanzi okuvamile.

3. Ukugcwaliswa ngemuva komsele wamapayipi
Imvula ina njalo ehlobo. Ngemuva kokwakhiwa, umsele wamapayipi kufanele ugcwaliswe emuva futhi ugxilwe ngesikhathi ukuze uvikele ukudilika komsele wepayipi ukuthi kuthinte ukwakhiwa okujwayelekile futhi kulimaze umzimba wepayipi. Lapho ugcwalisa i-backfill, inhlabathi izoba inhlabathi enhle, akukho zinto eziqinile ezizothintana ngqo nepayipi, futhi ukuqina komhlabathi omuhle ezinhlangothini zombili nangaphezulu kwepayipi kuzoba ngu-20-30cm.
4. Ukuhlolwa komfutho wepayipi
(1) Ngesikhathi sokwakha, i-valve yokukhipha umoya kufanele ifakwe endaweni ephakeme, futhi indololwane noma i-tee kufanele iqiniswe ngokhonkolo. Ngemuva kokufakwa kwepayipi, ngesikhathi sokuhlolwa kwengcindezi (ubude bepayipi obuyi-500m bufaneleka kakhulu), ukucindezela kufanele kwandiswe kancane, futhi i-valve yokukhipha umoya kufanele ivulwe ngesikhathi, ukuze igesi elisepayipini ikhishwe ngokugcwele. .
(2) Ngemuva kokuthi ingcindezi inyuswe ekucindezelweni okucacisiwe, ingcindezi ingakhululwa kuphela ngemuva kokuba ingcindezi igcinwe ihora elingu-1. Phakathi nesikhathi sokubamba ingcindezi, uma ingcindezi ishintsha phakathi kuka-0.05Mpa, kufakazelwa ukuthi akukho ukuvuza kwamanzi noma ukuphuka epayipini. Uma ingcindezi ishintsha kakhulu, kufakazelwa ukuthi kukhona ukuvuza nokuphuka kwamanzi epayipini. Ukuhlolwa kwengcindezi kuzomiswa ngesikhathi futhi ukulungiswa okuphuthumayo kuzokwenziwa. Ngemuva kokulungiswa okuphuthumayo, ukuhlolwa kokucindezela kuzokwenziwa futhi.
