Xoolooyinka HDPE Laba Qabiil oo Xaraysan oo loo yaqaan Habaynta Baadhitaanka Mugga Sare

Sareega dhulka la'aanta double wall corrugated ee loo isticmaalo dhexdhexaadka sarrad-guddoonka weyn ay leedahay awoodda inshinarka caafimaad leh oo ka saaraa staandardada cusub ee qof-kala-ka ah ee loo isticmaalo qalabka hoos jidad. Qaabka dib u eegsanaya dual-wall wuxuu kaga koobnaa dhulka sare gacan ku yar, oo ka dhigta gudaha, iyo dhulka korre la'aanta la'aan, oo abaal-cararkan tahay, si ay ula kala qaataan taliyadda hidroolik iyo awoodda mekaniikaaliga ah. Qorsheyaanka inshinarka waxaa imanaysa in sareegtan ay daawato awooda leh ee dhulka iyo xoolooyinka, halka ay sii socoto shaqada geesoodka goobo maamulka dhexdhexaadka. Qaabka la'aanta dhulka korre wuxuu sii kala socon jilicsanaanta jilicsan oo dhan dhulka sareegtii, si ay ilaalin lahaadaan jilicsanaanshaha mahadna leh oo laga yaabaa inay hortagto falalka horreeynta ee sharciga sareegyada single-wall guud. Sareenka inshinarka wuxuu hubiynayaa in thickness dhulka uu dhammaad la’aan yahay kila seensee sareegtii, si ay ilaalin lahaadaan nooc kasta oo jilib aan la’aanayn oo laga yaabaa inay xadgudbin karaan shaqada dheer-dhererka. Sareega hdpe double wall corrugated ee loo isticmaalo dhexdhexaadka sarrad-guddoonka weyn ay leedahay awoodda in la ilaalino stress environmental cracking, sabab muhiim ah ee loo isticmaalo sareegyada ku jira dhulka halka ay sareegtan ku soo baxaan chemistry iyo haalkeenna buluugga kala duwan muddo dheer. Tijaabooyinka lab-ka wuxuu tusayaa in sareegtan ay sii jeedin doonaan awoodda inshaarka iyagoo dura joogitaan muddo bilowdana 50 sano, si ay hubisid inshinarka inay sii jeedin doonaan qorshaha dhexdhexaadka. Qaabka polimerka caafimaad leh wuxuu siiyaa awoodda in la ilaalino oxidation iyo UV degradation, si ay ula jeedin doonaan shaqada marwalba marka ay ku sugan tahay aysaska ciyaarinta ama shaqsiyaadka sare.

Sifada xidhidda haydoolooki ah ee tubba hdpe labaad dhulka laabta ah ee loo isticmaalo dhexdhexaadka badan ee dhexdhexaadka waxbarashada ayaa muujiya horumarka weyn oo aad ugaaraysa farsaminta dhexdhexaadka, ka isticmaalaya qaybta sare ee ku taal si ay kordhibaan sida inay soo jeedin doonaan. Salka gaar ah ee dhowrka leh ayaa samaysa heer yar ah oo Manning's roughness coefficients, kaas oo sanan tahay 0.009 ilaa 0.012, kaas oo si wanaagsan ugu yaraan koridhinta iyo koridhinta midhaha laabta ah ee kale ee kaas oo leh friction factors sii weyn. Sidaas daraaddeed waxay keenaa kordhinta sare, sidoo kale tubagga yar yar ayuu heli kara volume-ka dhexdhexaadka laabta ah, kaas oo iman karta hoos u dhacnaha dhexdhexaadka iyo lacagta hoos u dhacnaha lagaga dhigayo. Xaqiiqda salka gudaha ayaa ilaaliya in khalad la jirto dhexdhexaadka ee laabta ah, kaas oo ilaalinaya inay socotaa laminaar throughout extended pipeline runs. Qeexidda computational fluid dynamics ayaa muujinaysa in hdpe double wall corrugated pipe for largescale drainage projects ay sii kordhibaan khaladka naga horumarayo turbulence iyo wall friction, si ay sistema gravity-fed ay u shaqeeyaan si fiican buuxda iyo hoos u dhacnaha. Salka gudaha ayaa ilaaliya in sediment ay dhaxliyaan iyo in ay dhaxlaan, kaas oo ilaalinaya inay socdaan si kasto mar hore, iyadoo aan la baahnayn in la saajiso si joogto ah. Dhexdhexaadka self-cleaning velocities ayaa la heli kara in ay dhacdo dhexdhexaadka yar yar, kaas oo sii yaraysa shaqsiyadda saajinta iyo lacagta shaqsiyadda degmoyinka. Teknolojiyada ugu horreeya ee ku daranta ayaa abuura salka gudaha gaar ah ee tubagga, ka saabsan inay jiraan joints iyo salka aan laabtin. Qaadashada tubba ayaa ilaaliya inay socdaan circular cross-sections under load, kaas oo ilaalinaya inay socdaan si kasto mar hore, iyadoo aan la baahnayn in la saajiso si joogto ah. Iimtixaanka pressure ayaa leh qaado gravity flow iyo low-pressure applications, kaas oo leh tusaale ha ka mid ah pumping stations ama elevated discharge points. Hdpe double wall corrugated pipe for largescale drainage projects ayaa muujinaysa inay socdaan si kasto mar hore, iyadoo aan la baahnayn in la saajiso si joogto ah.

Fa’iidooyinka lagu siiyaa in la dhiso odhoobka hdpe labaad midab ku xidhan oo xoog badan ee loo isticmaalo dhexdhexaadii daryeelka ay ka saamaysataan hababka taajiyadda, waxay siiyeen jirro iyo fududnimada aan la leh, taasoo siinaysa kala duwiddood si degdeg ah oo kala duwan iyo khaladka aad u yaraysa, halka annagga shaqaalaha iyo jirridda aysaan ku jirin. Qalloocidda qalabka, gaar ahaan 85% ka qalab kamid ah odhoobka konkreetka, wuxuu kuu kara in la qaato adigga yar yaryar iyadoo caawinaaya gacanta, halka adigga weyn wuu kara in la qaato iyadoo caawinaaya kiraana, taasoo kala duwida lixkooda iyo khaladka qalabka dhammaan meelaha taajiyadda. Hababka isku-dhiska la’aanta waxay kuu karaan in la isticmaalo hababka kala duwan ee taajiyadda, ka dib u dhaca hababka furinta tradishaniga ee geed-tiriilka ilaa hababka sare ee aan geed-tiriil ahayn, sida dowladda hor-taleeedka oo la’aantahay iyo dooshiga odhoobka, taasoo siiyaa injineerarka doorsoono kala duwan oo loo isticmaalo inay rasoobato goobta kala duwan iyo ugu yarayo jirridda dhulka. Habeennimada odhoobkii marka la dhiso wuu kara in la baahnado badan tahay midab iyo qalab kala duwan oo loo baahan yahay midabka qalabka kumid ah, taasoo kala duwida hawlaha lagu helo iyo fududda dhaqdhanka taajiyadda. Toleransiga heerkulka marka la dhiso wuu kara in la sameeyo taajiyadda sanadkii dhammaan, maxaa yeelay odhoobka hdpe labaad midab ku xidhan oo xoog badan ee loo isticmaalo dhexdhexaadii daryeelka wuu haysto fududnimada la xidhiidha in la isticmaalo sanadkii dhammaan, taasoo heerkulka kala duwan sanadkii kasta way kula noqon kartaa inay tahay qalabka qalab kamid ah. Hababka xiisaha arimaha waxay fudud tahay sababtoo ah in ay leedahay tijaabooyin caadiga ah iyo hababka isku-dhiska oo aamin ah oo siiyaa isku-dhasha aan lahayn baddal, taasoo aan yaqaan awoodda kala duwan ama waqtiga dheer ee barasho shaqaalaha taajiyadda. Hababka muduulka ah wuu kuu kara in la sameeyo taajiyadda sawir-sawir ah iyo in la siiyo mashruuc sawir-sawir ah, taasoo kuu kara in horumarinta infrastructuurka si degdeg ah u socdo marka lacagta la helo ama marka sawirrada horumarinta u baahan tahay in la kordhiyo awoodda daryeelka. Xasiloonida astaamaha taajiyadda waxay kuu karaan in ay leedahay astaamaha kala duwan, ka dib u dhaca istaamaha yar-yar ee reerka ilaa istaamaha sareee ee geed-tiriilka, halka astaamaha ring stiffness ay leedahay in ay leedahay shaqada kala duwan iyo aragga dhulka. Waxyaabaha lagu garto iyo lagu buuxsado ma ay tahin caadiga ah midabka tradishaniga, taasoo kala duwida qiimaha waxyaabaha loo soo intee iyo kala duwida waqtiga taajiyadda sababtoo ah fududka tijaabka iyo hababka compaction. Odhoobka hdpe labaad midab ku xidhan oo xoog badan ee loo isticmaalo dhexdhexaadii daryeelka wuu taageero hababka taajiyadda cusub sida slip-lining infrastructuurka hore ee la jaray, si ay u dhammaystooran muddada nagaadka bilaashka ah in la beddelo oo kasto, taasoo kala duwida jirridda magacyada faah-faahsan. Fa’iidooyinka aysaan ku jirin marka la dhiso waxay leedahay kala duwida carbon emissions marka la raacayo qalabka qalab kamid ah iyo kala duwida tirada tijaabka, taasoo taageero hababka taajiyadda sustainable ee inta badan loo baahan yahay agensiyyada xasiloonida iyo shaqaalaha bulshada.
