Ujeedooyinka ugu muhiimsan ee hagaajinta waxqabadka seismic ee dhuumaha sahayda biyaha waa laba: mid waa in la hubiyo awoodda gudbinta biyaha, si looga hortago dhul ballaaran oo cadaadiska biyaha ah, si loo awoodo bixinta biyaha dabka iyo xarumaha muhiimka ah ee degdega ah; Midda labaad waa in la yareeyo dhaawaca dhuumaha si loo fududeeyo dayactir degdeg ah. Si kale haddii loo dhigo, marka ay la kulmaan masiibooyinka dhulgariir, nidaamka bixinta biyuhu waa inuu lahaadaa la qabsi sare.
Kahortagga nasashada ugu muhiimsan ee biyuhu waxay lama huraan u tahay ilaalinta shaqada caadiga ah ee nidaamka bixinta biyaha. Nidaamka tuubbooyinka PE4710 (oo u dhiganta PE100) ayaa leh suurtogalnimada ugu hooseysa ee dillaaca iyo daadinta tubooyinka biyaha kasta, iyagoo ka caawinaya in la gaaro dhammaan ujeeddooyinka kor ku xusan.
Faafinta mowjadaha iyo qallooca dhulka ee joogtada ah ayaa ah sababaha ugu waaweyn ee burburka dhuumaha. Sababtoo ah jiritaanka xoogga axial iyo culeyska foorarsiga, dhaqdhaqaaqa dhulka wuxuu keenaa ciriiriga iyo foorarsiga dhuumaha. Walxaha leh qallafsanaan sare ( walbahaarka sare ee la oggol yahay) guud ahaan waxay leeyihiin awood xaddidan oo ay ku qalloociyaan. Maaddooyinka ductile ee uu matalo polyetylen (PE) ( walbahaarka la oggol yahay oo hooseeya) ayaa leh awood qallafsan oo wanaagsan.
Awoodda seismic ee nidaamka dhuumaha waxaa ka tarjumaysa la qabsiga cadaadiska dusha sare. ruxitaanka seismic ama hirarka hirarka seismic waxay keeni kartaa culays ku filan dhulka oo waxyeelo gaadhsiiya xataa tubooyinka ugu nugul. Dildilaaca cilladda, dhul go'a, carrada oo isu beddesha dhoobo iyo degitaanka iyo/ama fidinta dambe ee ka dhalata, hoos u dhaca dhulka iyo kor u kaca ayaa keeni kara cadaadis weyn oo dhulka ah, taasoo keenta burbur soo gaara meelo badan oo dhuumo ah oo duugan. Shaxda B-1 waxay taxaysaa xogta culayska dhulka ee lagu arkay aduunka oo dhan iyadoo ay ugu wacan tahay qallooca dhulka ee joogtada ah.

Qiyaasta loo baahan yahay cadaadiska dhulka ee dhuumaha waa inta u dhaxaysa 0.05% iyo 4.5%. Warbixintii 2008 ee Machadka Cilmi-baarista Awoodda Korontada ee Mareykanka, cabirrada awoodda culeyska walxaha PE4710 ayaa la bixiyay. Heerkulka 50°F (10°C), celceliska wax-soosaarka xajinta ee tuubada PE4710 waa 9.9%, halka celceliska cadaadiska ugu dambeeya uu yahay 206%. Tuubada polyetylenka ayaa u dhaqaaqi doonta si ay uga jawaabto dhaqaaqa dhulka, halkii ay iska caabin lahayd culeyska keeni kara in tubooyinka adag ama jajaban ay jabaan. Inta badan dhacdooyinka seismic, tuubada welded (welded) ee cufnaanta sare ee polyetylen (HDPE) way foorarsan doontaa, laakiin ma jebin doonto ama ma kala sooci doonto (isku xidhka aan shaabadda lahayn), sidaas darteed ilaalinta biyaha caadiga ah. Waa in la ogaadaa in dhammaan isku xirka tuubooyinka PE ee leh dhismayaal kale, tas-hiilaad dheeri ah iyo qaybaha laga yaabo inay ku xiran yihiin culeysyo kala duwan. Isku xirka qaybahan waa in si taxadar leh loo qorsheeyaa loona qaabeeyaa si loo yareeyo khatarta dillaaca.
Cadaadiska wax-soo-saarka dhuuban ee tuubada PE4710 waa ku dhawaad labanlaab ka culayska dhulka ee ay sababtay cabbirka ugu sarreeya ee la arkay, iyo culayska ugu dambeeya ee PE4710 wuxuu ka badan yahay 40 jeer cadaadiska dhulka ugu sarreeya. Waxqabadka lagu helay xisaabinta aragtida waxay la socotaa isticmaalka dhuumaha polyetylen ee dhulgariir. Khadka biyaha HDPE ee alxanka leh ayaa si fiican u sameeyay dhulgariirka. Jadwalka B-2 waxa uu bixiyaa indho-indheyn qayb ka mid ah dhulgariirradii hore ee Japan (Omuro iyo Himono, 2018).

Waxqabadka seismic ee dhuumaha waa in la qiimeeyaa, oo ay ku jiraan adayga, awoodda cidhiidhiga axial, radius qaloocin la oggol yahay, xoogga wadajirka ah, xasilloonida iyo xaaladda dhuumaha hadda jira. Tiro badan oo waayo-aragnimo seismic ah ayaa tusinaysa in biyo-bixinta HDPE-da ee dhuumaha waaweyn ee waafaqsan heerarka taxanaha tuubooyinka ASTM ay sii wadi karaan hawlgalka caadiga ah marka loo eego xaaladaha culeyska seismic. Marka shuruudaha waxqabadka seismic ee tuubada ugu weyn ee biyaha ay sarreeyaan, isticmaalka tuubooyinka HDPE ee alxanka leh waa in la tixgeliyaa, sababtoo ah waxqabadka seismic ee tuubooyinka HDPE waa mid la isku halleyn karo, waxayna la qabsan karaan noocyada kala duwan ee dhulka ee dhulgariirka ka dhasha oo ay sii wadaan hawlgalka caadiga ah.
