HDPE Corrugated Pipe Double Wall: Furfurinimo Siyaasadda Korontada si Gaar ah ee Qaabdhismeedka Hore

Salka hdpe corrugated pipe double wall waxaa la sameeyay farsamada farshaxanka oo ka saamaysan awoodda dib-u-hodbinta iyo xajminta caafimaadka iyo furfurinta shaqada. Habka qabaal wixii kala duwan ayaa leh dhul walba gacan ku wareeg ah oo hubinaya inay leedahdo tijaabooyinka haaydiroliikii fiican, halka dheerka sareynta laga yaabato oo leh tahriib lagu siiyo awood darro badan iyo jiid. Sidaas daraaddeed ayaa habka noocan ah salka inay gaadhato qiimaha korodhka cirka (ring stiffness) sano sanan oo kaliya marka ay haysataan dhul walba yar, taasoo abuunaysa khalbadhigga caafimaadka siinaysa awoodha dib-u-hodbinta. Salka tahriibta sare ee dhexeeya way ku darsan tahay xajmihii la socda oo dhan, ka dhigaysa in xajmihii loo bixiyo goobtayd ah oo kale (localized stress concentrations) taasoo sabab u noqon kara inay dhammaan ama la jebin karaan xajmiga dhexe. Sidaas darteed habka dib-u-hodbinta ayaa salka hdpe corrugated pipe double wall ku dhashaa inay ilaaliyaan dhererka sare ee la dhiso iyo xajmiga la socda, halka ay raacdaan muuqaalka geesiga iyo awoodda diridda. Tabbacarka tabbacsiga ayaa hubinaya inay leedahdo heysiga heysta siisnimnimo iyo sifeynta dhul walba si buuxda, abuunaysa awoodda dib-u-hodbinta mid ah oo dhammaan salla. Qorshaha labaad ee dhul walba ayaa sidaas darteed ku dhashaa inay haysataan dib-u-hodbinta qoto ah, halka dheerka sareynta ay la xajmi jirto xajmihii sarreeynta, halka dheerka hoose ay ilaaliyaan awoodha haaydiroliikii iyo siiyaan taageerad dheeriye. Habkan ayaa ku dhashaa in kala duwanaansho awoodha dib-u-hodbinta si loo hargeliyo xajmiga inkaar-galka, ka duwan hababka qabiilka qofkasta. Salka tahriibta ayaa kordhinaya inkaar-geeska (moment of inertia), siiyaya awood darro badan in la soo noqdo xajmiga la socda iyo jidka la socda. Awoodda dib-u-hodbinta ee salka hdpe corrugated pipe double wall ayaa ka sii kala duwan kartida qabiilka kale, waana awoodda jiidka, taasoo ku dhashaysa inay ilaaliyaan dhibaatada dalka iyo jidka dhowrka (thermal movements) iyagoo la jabin inay abuurto cracks ama jidka loo jabin. Tijaabada calaamadda awoodda dib-u-hodbinta ayaa hubinaya inay fulsanaan xajmihii la socda, taasoo hubinaya inay fulsanaan shaqada ku tiirsan joogga iyo shaqooyinka kala duwan.

Dhisidda haydrolig ah ee hdpe corrugated pipe double wall ayaa ku qorshay dhaawacyada gudaha buuxa oo wanaagsan oo ka dhigaysa in ka hortagga iskushubminta iyo in kala duwanaanshii dhaawac si degdeg ah ay joogto muddo karsheeda. Wartidka warbixinta gudaha ayaa sambar weyn si degdeg ah loo sameeyay, taasoo iskudhufan karta isku dayninta iyo isku dhafkaanka, iyadoo loo hortagi karta in kala duwanaanshii dhaawac. HDPPE corrugated pipe double wall-ka ayaa leh awoodda haydrolig ah si degdeg ah marka loo eego xaaladaha shaqada jaban, sida la hadlay saamaynta alaabta iskushubminta, habaynta kiimikiga, iyo jebinta jiritaanka oo kale ee laga yaabaa inay geedifkaan tahay alaab kale. Warbixintu gudaha ayaa iskudhufan karta in la gooyo alaab, waxayna caawinaysaa in la saaro natiijada iskushubminta marka la socdo, taasoo ku hortagaya in la baadhado iyo in la ilaaliyo in kala duwanaanshii dhaawac. Xisaabinta socodka ayaa muujiyay in ay leedahay awoodda ka bixinta sanasiga badan kama aydhanaan gudaha konkreeti ama dhagax, taasoo oggola in la isticmaalo buubno yar-yar badani marka la socdo, laakiin socodka ma ugu badan. Dhisidda haydrolig ah ayaa leh awoodda in la qabsado socodka kala duwan, ka dibadda socodka yar ilaa waqhtiga dabaaladeed, iyadoo aan kala jarjarin, taasoo oggola in lagu shaqayo si fiican qaarkoodba. Warbixintu gudaha ayaa iskudhufan karta saamaynta kiimikiga ee biyaha biyo-mara, waxayna iskudhufan kartaa in kala duwanaanshii dhaawac oo ka dhigaysa in ka hortagga iskushubminta muddo dheer. Awoodda jebinta ayaa iskudhufan karta in kala duwanaanshii dhaawac si degdeg ah muddo khamriga iyo marka la isticmaalayo biyo ceebla ah ama marka la eego xaaladaha jebinta sare. Dhisidda hdpe corrugated pipe double wall ayaa iskudhufan karta in la jebin karto qalabka soo noqnoqda ee kaloo jira alaab kale, taasoo iskudhufan karta in la socdo si degdeg ah, iyadoo aan kala jarjarin, taasoo iskudhufan karta in kala duwanaanshii dhaawac. Tijaabada haydrolig ah ayaa muujiyay in socodka ayaa si fiican u dhiso mugga, taasoo sheegaya in dhisidda haydrolig ah ayaa sax ah iyo inay leedahay awoodda si degdeg ah qaarkoodba.

Fa’iidooyinka lagu siiyo in la dhiso tubaalka hdpe corrugated pipe double wall ay si toos ah ugu horreeya khalad aad u qorsheyn karta iyo xirfadaha mashruucadda oo dhan iyagoo ka caawinaya maamulka, madaxweynayaasha iyo waalidiyada magaalada ee dhammaan nolosha mudahooda. Tubaalka yar bixinta ay kordhinayso baahimaha mashinarka loo baahan yahay marka la tixgeliyaa iyo marka la dhiso, taasoo saameyn ku jirta in kala jarida lama baahno iyo khaladka inta la tixgelinayo tubaalka. Xirfadda in la dhiso tubaalka hdpe corrugated pipe double wall waxay leedahay mid walba in la dhiso, iyadoo leh in la tixgelin karo tiro, dib u hakansho iyo helitaanka tubaalka, taasoo iibsaasi u yeelanaya in la yaabiyo shaqada sare iyo khaladka dib u habboon. Qudhmin karta mudafalka ay leedahay waxay kordhinaysaa in tubaalku ka baxdo mudafalka hore iyo xoolooyinkana iyado ma baahna tahay kaafi ama helitaannada gaaban, taasoo kordhinaya xirfadda mashruucadda iyo khaladkooda. Hababka joint ee lagu gundhisiyey tubaalka hdpe corrugated pipe double wall waxay iibsaasi u yeelanaan tahay in la samayn karaa dambiyada si gooniyeed sharafta, taasoo kordhinaya wakhtiga la tixgeliyaa iyo khaladka laboor-ka ka dib marinka soo guurida. In tubaalku ilaaliyo khaladka marka la tixgeliyaa ay kordhinayso khaladka dib u samaysida iyo beddelida marka la shaqeysiiyaa, taasoo hubinaya in mashruucaddu yihiin daaqda iyo badhanka aad u socotaa heerka. Wajiidka in la tixgeliyo tubaalka hdpe corrugated pipe double wall ay ka yar tahay tubaalka rigida, taasoo kordhinaya khaladka baahimaha iyo wakhtiga la tixgeliyaa, halkaas oo kale wajibaadka jiidka saxda ah ay ka hadlin tahay. Qodobka in tubaalku ilaaliyo korrosion ay kordhinayso khaladka in la samayn karo daryeelka cathodic ama isku daynta ilaalinta, taasoo kordhinaya khaladka la tixgeliyaa marka hore iyo khaladka dib u eexidda dheer suurta ah. Xiriirka awoodga aad u habboon marka loo abuuray tubaalka ay hubinaysaa in ay tahay mid sameyn kasta iyo wakhtiga la tixgeliyaa, taasoo kordhinaya wajibaadka sharafta oo kale ay ka dambeeyeen in ay dabadeed ka dambeeyeen. Tubaalka hdpe corrugated pipe double wall ay u baahimaan khalad aad u yar nolosha wakhtiga, iyadoo leh in la fiiriyo iyo la safarayo si fudud sababtoo ah runta aragtida sare iyo qodobka ilaalinta kiimikada. Nolosha mudnaanta ay ka weynaa 100 sano sharafta caadiga ah, taasoo iibsaasi u yeelanaa in lacagta lagu soo saaray ay ka wayn tahay tubaalka caadiga ah oo periodic ay baahnaan in la beddelo ama la dib u habboono. Sababtoo ah in ay noqon karaan dhici lahayd HDPE marka nolosha ay joogto ay iibsaasi u yeelanaan fa’iidooyin ekobeen iyo maaliyadeed, taasoo taageeraya horumarinta infrastructuur ee macaamil ah iyo khaladka dib u keynta dheer suurta ah.
