I-GB/T 20933 Hot Rolled Q235B Q355B Steel Sheet Pile Locking kanye nokusebenza okungangeni manzi
Umklamo: Inqwaba Yeshidi Lensimbi Exhumeneyo, ukuvuleka kwamanzi ≤1×10⁻⁷ cm/s
AseMelika: Ihlangabezana ne-ASTM D5887 Standard ye-Liner yokunciphisa ukuvuza ngaphansi kwezigubhu
INingizimu-mpumalanga ye-Asia: Ivikela amanzi angaphansi komhlaba ezinkathini zemvula zasezindaweni ezishisayo
Inqubo Yokukhiqiza Inqwaba Yensimbi Eshidiwe Yensimbi ye-GB/T 20933 Eshisayo Egoqwe Q235B Q355B
1. Ukukhethwa Kwezinto Ezingavuthiwe
Ama-billet ensimbi yesakhiwo sekhabhoni esezingeni eliphezulu (Q235B / Q355B) akhethwa ngokucophelela futhi ahlolwe ukuqinisekisa ukuthi ukwakheka kwamakhemikhali kuhlangabezana nezindinganiso ze-GB/T 20933.
2. Ukushisa kwe-Billet
Ama-billet ensimbi ashiswa esithandweni sokushisa esiqhubekayo cishe1150–1250°C, ukuqinisekisa izinga lokushisa elifanayo ukuze kusebenze kahle kakhulu ukugoqa.
3. Ukugingqa Okuyinhloko (Ukugingqa Okungafanele)
Ama-billet afudumele adluliswa ezigayweni ezigoqekayo ukuze kuncishiswe ukujiya futhi kwakhiwe izimo zokuqala.
4. Qedela Ukugoqa
Insimbi icutshungulwa kabanzi ngokusebenzisa izigayo zokuqeda ukuze kufezwe ubukhulu obuqondile, ukujiya, kanye nezakhiwo zemishini ezidingekayo kuma-sheet piles.
5. Ukwakheka Kwephrofayili
Kusetshenziswa imishini ekhethekile yokugoqa, insimbi ibunjwa ibeAma-sheet piles ohlobo lwe-U noma lwe-Z, ukuqinisekisa ukuthi imiphetho exhumene kahle iyasebenza ekwakheni.
6. Ukupholisa Okulawulwayo
Izinqwaba zamashidi zipholiswa umoya ngokulawulwa noma zipholiswe ngokushesha ukuze kulungiswe isakhiwo sokusanhlamvu futhi kufezwe amandla nokuqina okudingekayo.
7. Ukuqondisa Nokuqondanisa
Izinqwaba zamashidi eziqediwe ziqondiswa kusetshenziswa imishini yokulinganisa ukuze kuqinisekiswe ukunemba kobukhulu kanye nokuqondana okufanele.
8. Ukusika Nokwenza Ngokwezifiso Ubude
Izinqwaba zensimbi zinqunywa ngobude obudingekayo (ngokuvamile6m–18m) ngokuqeda noma ukucwebezela okukhethwa kukho.
I-GB/T 20933 Hot Rolled Q235B Q355B Steel Sheet Pile Surface
AseMelika:HDG njenge-ASTM A123 (ingubo encane ye-zinc ≥ 85 µm); ukugqoka kwe-3PE kungakhethwa; konke ukuqeda kuhambisana ne-RoHS.
INingizimu-mpumalanga ye-Asia:Ubukhulu be-hot dip galvanized yi-hollyh (ngaphezu kuka-100μm), futhi kufakwa izendlalelo ezimbili ze-epoxy coating coating tar, ingafuthwa ngosawoti ihlolwe amahora angu-5000 ngaphandle kokugqwala, iyona engcono kakhulu ekusetshenzisweni kwemvelo yasolwandle eshisayo.
ISICELO
1. Inqwaba Yensimbi Yokwakha Ichweba:Isetshenziselwa ukwakha amachweba, amachweba, kanye nezindonga ze-quay, inikeza ukwesekwa okuqinile kwesakhiwo kanye nokuqina kwesikhathi eside ezindaweni zasolwandle.
2. Inqwaba Yensimbi Yokuvikela Ibhange Lomfula:Yakhelwe ukuqinisa amabhange emifula, ukuvimbela ukuguguleka kwenhlabathi, nokuvikela ekushayweni kwamanzi kanye nezikhukhula.
3. Inqwaba Yensimbi Yesisekelo Sebhuloho:Kusetshenziswa ekwakhiweni kwamabhuloho ukuhlinzeka ngokusekelwa okujulile kwesisekelo nokuqinisekisa ukuqina kwesakhiwo ngaphansi kwemithwalo esindayo.
4. Isakhiwo Esingaphansi Komhlaba Inqwaba Yensimbi:Kusetshenziswa ezindlini ezingaphansi komhlaba, emihubheni, nasezindaweni ezingaphansi komhlaba ukuze kunikezwe ukwesekwa okuthembekile kokugcinwa komhlaba kanye nokumbiwa.
Kungani Ukhethe Insimbi Yasebukhosini YaseShayina Yezinqwaba Zeshidi Lensimbi
1. Amandla Aphezulu Nokuqina
Amagremu Ensimbi e-Q235B kanye ne-Q355B ahlinzeka ngesivuno esihle kanye namandla okuqina, amandla amahle okuthwala umthwalo kanye nokuzinza kwesakhiwo isikhathi eside endaweni yokwakha enzima njengesicelo sasolwandle kanye nesisekelo.
2. Amaphrofayili Amaningi Ayatholakala
SinikezaIzinqwaba zamashidi ohlobo lwe-U kanye nohlobo lwe-Zngezinhlelo ezinembile zokukhiya, okunikeza umakhi umugqa wezinketho zokuklama eziguquguqukayo ukuze kuhlangatshezwane nezidingo ezahlukene zobunjiniyela okuhlanganisa izindonga zokugcina, ama-cofferdams kanye nezisekelo ezijulile.
3. Izinketho Zokumelana Nokugqwala
Ukuphela kobuso Ukwelashwa ngogesi oshisayo, okuvimbela ukugqwala, impilo yesevisi ithuthuka kakhulu, le mikhiqizo ingasetshenziswa ezindaweni ezibucayi njengamanzi olwandle, ogwini lomfula, indawo enomswakama ophezulu njll.
4. Ukwenza ngokwezifiso okuguquguqukayo
Sisekela ukwenza ngokwezifiso okuphelele kobude (6m–18m), ukujiya, ububanzi, kanye nokucubungula okukhethekile (ukusika, ukubhoboza, ukwelashwa komphetho) ukuze kuhlangatshezwane nezidingo ezithile zomklamo wephrojekthi nobunjiniyela.
5. Isitoko Esikhulu Nokutholakala Okusheshayo
Njengoba sinamathani angaphezu kwe-1000+ esitokwe esilungile, siqinisekisa ukucutshungulwa okusheshayo kwama-oda kanye nokunikezwa okuzinzile, sisiza amakhasimende ukunciphisa ukubambezeleka kwephrojekthi kanye nengcindezi yempahla.
6. Intengo Eqondile Yefektri
Sihlinzeka ngqo kusuka efektri yethu futhi akukho muntu ophakathi nendawo, okusivumela ukuthi sikunikeze intengo engcono kakhulu, ikhwalithi eqhubekayo kanye nensizakalo engabizi kakhulu yama-oda amaningi kanye namaphrojekthi esikhathi eside.
UKUPHAKISHA NOKUTHUMELA
Okwethuizinqwaba zeshidi lensimbizigcwele kahle ngezintambo zensimbi ezinamaphrotheni amaningi ezihambisana namakhona okuvikela ukugwema ukugoba noma ukufiphala ngesikhathi sokuphathwa. Kuma-mountain agqitshiwe noma apendiwe, ukugoqa okuncishisiwe noma ukupakishwa okumboziwe kunganikezwa njengendlela yokuvikela ekugqwaleni ngesikhathi sokuthunyelwa isikhathi eside noma kolwandle. Ama-mountain angathunyelwa ngeziqukathi, ama-flat racks, imithwalo emikhulu futhi konke ukuphathwa kwenziwa ngezinga lokuphepha eliqinile ukuqinisekisa ukuthi uthola ama-mountain esesimweni esihle kakhulu endaweni yakho zingakapheli izinsuku eziyi-7 - 15.
