Ujeeddooyinka ugu waaweyn ee hagaajinta waxqabadka seismic-ka ee dhuumaha biyaha waa laba: mid waa in la hubiyo in la iibiyo biyo gudbintiisa, si ay u awoodaan inay biyo u siiyaan dabka iyo tas-hiilaad xasaasi ah xaalad degdeg ah; Ta labaad waa in la yareeyo burburka dhuumaha si loo fududeeyo hagaajinta degdegga ah. Si kale haddii loo dhigo, markii la wajaho masiibooyinka Dhulgariir, nidaam biyo ah waa inuu lahaadaa mid aad u waafajin ka sareysa.
Ka hortagga biyuhu waxay muhiim u tahay joogtaynta hawlgalka caadiga ah ee nidaamka biyaha. PE4710 (U dhiganta PE100) Nidaamka PE100) ayaa leh itimaalka ugu hooseeya ee dillaaca iyo baxsiga tuubbada biyaha, gacan ka geysashada sidii loo gaari lahaa dhammaan ujeeddooyinka kor ku xusan.
Faafinta jajabinta iyo is-xakamaynta dhulka joogtada ah waa sababaha ugu waaweyn ee burburka dhuumaha. Jiritaanka xoogga xoogga iyo culayska, dhaqdhaqaaqa dhulka wuxuu horseedaa xargaha xun iyo foorarka ee dhuumaha. Qalabka leh adkaanta sare (walaac sare oo la ogolaan karo) guud ahaan waxay leeyihiin awood xaddidan oo ku habboon. Qalabka Dantile ee ay mataleen Polyethylen (PE) (PE PE) (walaaca hoose ee la ogolaan karo) waxay leeyihiin awood cagaaran oo wanaagsan iyo adkeyn.
Awoodda seismatic ee nidaamka dhuumaha ayaa laga muujinayaa laqabsashada culeyska dusha sare. Faafinta mawjadda ama mawjadaha mawjadaha ee jajaban ama mawjadaha jajaban waxay sababi karaan culeys dhulka ku filan oo waxyeelo u geysta xitaa tuubooyinka ugu nugul. Jabniintii qaladka, dhul-gariirrada, carrada ayaa loo beddelaa dhoobada iyo dejinta natiijada iyo / ama fiditaanka dambe, hoos udhaca dhulka, taasoo dhalisay waxyeelo weyn, taasoo dhalisay waxyeelo aagagga waaweyn ee lagu aaso. Shaxda B-1 ayaa liis gareeya xogta xasaasiyadeed ee xaragada oo lagu arkay adduunka oo dhan sabab u ah is-dhexgalka dhulka oo joogto ah awgeed.

Baaxadda ugu badan ee loo baahan yahay ee loogu talagalay dhuumaha ayaa u dhexeeya 0.05% iyo 4.5%. Warbixinta 2008 ee ay soo saartay Machadka Cilmi baarista Korontada ee Mareykanka, cabirka khamaarka culeyska ee sheyga PE4710 ayaa la siiyay. 50 ° F (10 ° C), celcelis ahaan culeyska dhalidda ee khafiifka ah ee PE4710 tuubbada ayaa ah 9.9%, halka celceliska dulqaadashada ugu dambeysa uu yahay 206%. Tuubada polyetylene waxay u dhaqaaqi doonaan wax ka qabashada dhaqdhaqaaqa dhulka, halkii ay ka hor imaatinka ka noqon lahaayeen xamuul sababi kara tuubooyin adag ama tuubooyin jilicsan oo jabsan. Dhacdooyinka ugu badan ee seisical, waaxda dharka (welded) Pronenty Proytylent (HDPE) Tlowpe ayaa laaban doona, laakiin ma jabin doono ama kala saari doono (isku xirka aan xirnayn), sidaas darteedna dayactirka biyaha caadiga ah. Waa in la ogaadaa in dhammaan isku xirnaanta PEP ay ku jiraan qaabab kale, tas-hiilaadka dhaqashada iyo qaybaha laga yaabo inay ku hoos jiraan culeysyo kaladuwan. Xiriirinta qaybahan waa in si taxaddar leh loo qorsheeyaa loona habeeyey yareynta halista dillaaca.
Cadaadiska dhalmada ee torta ah ee PE4710 ayaa qiyaastii laba jibaar ah oo ah culeyska dhulka ee ay sababtay ugu badneyd ee la arkay, iyo culeyska ugu dambeeya ee PE4710 ay ka badan tahay 40 jeer oo ka mid ah culeyska ugu sarreeya. Waxqabadka laga helay xisaabinta fikradda ayaa la jaan qaadaya adeegsiga dhuumaha polyetylen ee dhulgariir. Khadka sahayda biyaha ee Hdpe ee HDPE si fiican ayuu u qabtay dhulgariirkii. Shaxda B-2 waxay siisaa qayb ka mid ah indha indheynta dhulgariirkii hore ee Japan (Omono iyo Himono, 2018).

Waxqabadka seismatic ee dhuumaha waa in la qiimeeyaa, oo ay ku jiraan kartida adag, awoodda xasaasiga ah, xoojinta foosha, xoogga wadajirka ah, xasilloonida iyo xaalada dhuumaha ee jira. Tiro badan oo khibrad u badan ayaa muujisay in Biyaha Biyaha ee Biyaha ee HDPE ay la jaan qaadayaan heerarka taxanaha tuubooyinka ASTM inay ilaalin karaan howlgalka caadiga ah ee ka hooseeya xaaladaha rarka caadiga ah. Marka shuruudaha waxqabadka ee seisic ee keega biyuhu ay aad u sarreeyaan, isticmaalka tuubooyinka welleed ee loo yaqaan 'HDPE' waa in la tixgeliyaa, sababtoo ah waxqabadka dhulgariir ee HDPE ee ay ka soo baxaan noocyada dhulka ee ay abuuraan dhulgariirku waxay ka dhaliyaan hawlgal caadi ah.
