Iindaba - Iinqwaba zePhepha zeNsimbi zohlobo lwe-Z zaseMalaysia | Iinkcukacha zoBugcisa kunye neSikhokelo sokuLungisa iNdawo

Ishishini lokwakha elikhulayo eMalaysia—ukusuka kwiiprojekthi zokwandisa ePenang nasePort Klang ukuya kwimisebenzi yokukhusela unxweme eSabah kunye nokwakhiwa kweziseko ezinzulu zezakhiwo ezinde eKuala Lumpur—kuye kwakhokelela kwiinjineli ukuba zicingeIinqwaba zeshiti ezimile okwe-Znjengokhetho olukhethwayo. Indawo yabo eyahlukileyo efana no-Z, iipropati ezibalaseleyo zoomatshini, kunye nokusebenza kakuhle kweendleko zihambelana ngokugqibeleleyo neemeko zejoloji ezintsonkothileyo zaseMalaysia (izakhiwo zomhlaba othambileyo ezinamaleko amaninzi, amaza aphezulu) kunye neekhowudi zezakhiwo zesizwe. Esi sikhokelo sigxininisa iiparameter zobugcisa eziphambili, usetyenziso lwasekhaya, kunye nemizekelo yeprojekthi yehlabathi lokwenyani, esebenza njengesalathiso soyilo, ukuthengwa kwezinto, kunye nokwakhiwa.

Imigangatho yoLawulo: Ukuthobela imithetho yengingqi neyehlabathi

Iinqwaba zamaphepha zohlobo lwe-Z zeRoyal Steel Group ezithunyelwe eMalaysia zihambelana ngokupheleleyo nemigangatho yehlabathi neyengingqi, ziqinisekisa ukhuseleko, ukuqina, kunye nokuvunywa kweprojekthi:

- Umgangatho weHlabathi:EN 10248-2:2024 (Iinqwaba zesinyithi eziqengqelekayo ezishushu), ezichaza ubukhulu bokunyamezelana, ukuthe tye, kunye nomgangatho ukuqinisekisa umgangatho ohambelanayo.

- Umgangatho waseMalaysia:Ithobela i-MS EN 1993, i-JKR 2020 Standard Code for Building Works, kunye neCandelo 10 (Pile Foundations) leMisebenzi yeNdlela, ihlangabezana neemfuno zeeprojekthi zikarhulumente nezabucala.

- Isiqinisekiso:Iqinisekiswe yi-CIDB, ithobela imimiselo ye-RoHS/REACH, ifanelekile kwiiprojekthi zonxweme kunye neendawo ezimanzi ezinobuthathaka kwindalo eMalaysia.

IiParamitha zoBugcisa eziPhambili (uthotho lwe-AZ olukhethekileyo lwaseMalaysia)

Iipali zeRoyal Steel ze-AZ ezishushu ezijikelezileyo ze-Z zohlobo lweRoyal Steel zilungiselelwe iimfuno zobunjineli baseMalaysia (iziseko ezinzulu, ukulungiswa kwakhona konxweme, amazibuko). Iiparameter eziphambili (inkqubo yemetrikhi, ehambelana nemikhwa yendawo) ziboniswe ngezantsi:

Imodeli (Uthotho lwe-AZ)	Ububanzi beCandelo eliNqamlezileyo (mm)	Ubude beCandelo eliMnqamlezo (mm)	Ubunzima ngeMitha nganye (kg/m)	Ixesha lokungakhathali (cm⁴/m)	I-Elastic Section Modulus (cm³/m)	Uluhlu lobude (m)
AZ13-770	770	345	79.5	22360	1300	6-12
I-AZ26-700	700	460	102.9	59720	2600	6-18
I-AZ38-700N	700	499	126.4	89610	3795	9-18
I-AZ46-700N	700	501	157.7	110150	4405	12-24

Izinto eziphambili zeParamitha eMalaysia

Indawo yokudlula:Ububanzi obuyi-700-770mm bunciphisa ubungakanani beenqwaba ngemitha nganye, nto leyo ekhawulezisa ukwakhiwa (kubalulekile kwiiprojekthi zezibuko ezixineneyo). Ukuphakama okungu-345-501mm kulinganisela amandla kunye neendleko zeziseko ezinzulu (>15m).

Ubunzima:I-79.5-157.7kg/m ilungele ukuthuthwa/ukuphakamisa izinto zasekuhlaleni. I-AZ13-770 yokuxhasa isixeko okwethutyana; i-AZ46-700N yokubuyisela ulwandle olunomthwalo omninzi.

Ukumelana nokugoba:I-AZ38-700N/AZ46-700N inertia ephezulu (89610-110150 cm⁴/m2) imelana nomhlaba othambileyo kunye noxinzelelo lolwandle—ilungele iiprojekthi zaselunxwemeni.

Ubude:I-6-24m igubungela uninzi lweemfuno; ukufakelwa okwenziwe ngokwezifiso kuhambelana nemigangatho ye-JKR kwiiprojekthi ezikhethekileyo.

Iiparameter zezinto: Ezilungelelaniswe neMozulu yaseMalaysia

Imekobume eshushu, efumileyo neyonxweme lwaseMalaysia ifuna ukumelana nokugqwala okuphezulu.Iinqwaba zohlobo lwe-Zsebenzisa intsimbi yolwakhiwo esemgangathweni ophezulu ngezi nkcukacha zibalulekileyo:

Inqanaba:Isinyithi esitshintshayo se-S355GP/S355J2W (isivuno esingu-≥355MPa, ukutsalwa okungu-470-630MPa, ukunwebeka okungu-≥21%) ukuze sihlale ixesha elide kwiimeko ezinzima.

Ukhuseleko lokugqwala:I-hot-dip galvanizing (Zn ≥80μm) okanye i-epoxy coating (≥200μm) yandisa ubomi benkonzo ukuya kwiminyaka engama-50+ kwiindawo eziselunxwemeni—iphinda kabini ubomi beepile eziqhelekileyo.

Amandla Oomatshini:Amandla empembelelo ≥34J (-20℃) athintela ukwaphuka okubuthathaka ngexesha lokuthuthwa/ukufakwa, nto leyo ehlangabezana neemfuno zoxinzelelo lwe-JKR.

Amatyala eProjekthi yasekuhlaleni: IiPiles zohlobo lwe-Z ziyasebenza

Iiprojekthi zokwenyani eMalaysia zibonisa ngokupheleleyo iziphumo ezibalaseleyo ezifunyenwe yi-Iinqwaba zesinyithi zentsimbi zohlobo lwe-Z:

Iprojekthi Yokwandisa Izibuko lasePenang:Iipali ze-AZ38-700N(Iimitha ezili-12-18 ubude, ixesha lokungakhathali eliyi-89610 cm⁴/m) zasetyenziswa ukuxhasa isiseko esinzulu sechweba. Amandla azo aphezulu okugoba anokumelana namandla aqinileyo okuhamba kwamanzi kunye noxinzelelo lomhlaba oluthambileyo, kwaye xa kuthelekiswa neenqwaba ze-U-type, ixesha lokwakha lifinyezwe nge-15%. Ukuthobela imigangatho yeSebe leMisebenzi yoLuntu (i-JKR) kuqinisekisile ukuvunywa kweprojekthi ngokulula.

IProjekthi yoBuyiselo lweSutera Bay, eSabah:Iipali ze-AZ46-700N (157.7 kg/m, i-epoxy coating) zasetyenziselwa ukuvuselela unxweme. Uyilo lwazo oluqinileyo kunye nokukhuselwa kokugqwala kumelana nokutshizwa kwetyuwa kunye notshintsho oluqhelekileyo lolwandle, okunciphisa iindleko zokulungisa ngama-40% kwiminyaka emihlanu. Iinqwaba ezenziwe ngokwezifiso eziziimitha ezingama-20 ubude zihlangabezane neemfuno zale projekthi emanzini anzulu.

Iziseko zeZakhiwo eziPhakamileyo zaseKuala Lumpur:Iipali ze-AZ13-770(iimitha ezi-6-10) zasetyenziselwa ukuxhasa isiseko sendawo okwethutyana. Uyilo lwayo olukhaphukhaphu (79.5 kg/m) lwenza kube lula ukusebenza kokuphakamisa kwiindawo zasezidolophini, ngelixa i-section modulus yayo ye-1300 cubic centimeters/m iqinisekisa uzinzo lwesakhiwo kumhlaba othambileyo wasezidolophini.

Intsimbi yasebukhosiniIinqwaba zesinyithi zentsimbi zohlobo lwe-Zdibanisa iiparameters ezimiselweyo, ukuthobela imithetho yendawo kunye nokusebenza okuqinisekisiweyo kweprojekthi—ilungele iiprojekthi zeziseko zophuhliso zaseMalaysia. Iqela lethu lobuchwephesha lendawo libonelela ngesikhokelo kwindawo yokukhetha iiparameters, ukufakela kunye nokugcinwa kwazo.

QhagamshelanaIqela leNsimbi yasebukhosininamhlanje ukuze ufumane incwadi yemiyalelo yobugcisa eneenkcukacha kunye nesicatshulwa esenziwe ngokwezifiso seepali zesinyithi zohlobo lwe-Z esilungiselelwe iprojekthi yakho yaseMalaysia.
