Iindaba - Iinqwaba zePhepha leNsimbi yohlobo lwe-U kuMzantsi-mpuma we-Asia: Imfuno yeMarike, amaBanga aQhelekileyo, ubungakanani, kunye neSikhokelo sokuThenga

Umzantsi-mpuma we-Asia—ikhaya lezinye zezixeko ezikhula ngokukhawuleza elunxwemeni kunye nemilambo—ixhomekeke kakhulu kwiinqwaba zesinyithi ukuze kuphuhliswe ulwandle, izibuko, kunye neziseko zophuhliso. Phakathi kwazo zonke iintlobo zeenqwaba zeshiti,Iinqwaba zesinyithi zentsimbi zohlobo lwe-Uzezinye zeemveliso ezichazwe rhoqo ngenxa yokunxibelelana kwazo okuqinileyo, i-deep section modulus, kunye nokuguquguquka kwimisebenzi yexeshana nesisigxina.

Amazwe afana neIMalaysia, iSingapore, iVietnam, iIndonesia, iThailand, kunye nePhilippinessebenzisa kakhulu iinqwaba zamaphepha ezi-U-type ekuphuculeni amazibuko, ekukhuseleni unxweme lomlambo, ekulungiseni umhlaba, nakwimisebenzi yesiseko.

Amanqaku aqhelekileyo eNsimbi kuMzantsi-mpuma we-Asia

Ngokusekelwe kwiindlela zokuthenga zengingqi, iinkcukacha zobunjineli, kunye nemigca yemveliso yababoneleli, la manqanaba alandelayo alawula imarike:

●S355 / S355GPIinqwaba zePhepha zeNsimbi zohlobo lwe-U

Ikhethwa kwizakhiwo ezisisigxina

Amandla aphezulu, afanelekileyo kwiindawo zokumba ezinzulu nakwiimeko zonxweme

Ixhaphakile kwiziseko zophuhliso zaselwandle nakwizibuko

●S275Iinqwaba zePhepha zeNsimbi zohlobo lwe-U

Ukhetho olungabizi kakhulu kwiiprojekthi zomsebenzi ophakathi

Isetyenziswa kwimisebenzi eselunxwemeni lomlambo, ii-cofferdams zexeshana, kunye nenkxaso yesiseko

●SY295 / SY390Iinqwaba zePhepha leNtsimbi ze-U (Imigangatho yaseJapan neye-ASEAN)

Isetyenziswa kakhulu kwiinkcukacha eziphenjelelwe yiJapan (ingakumbi eIndonesia naseVietnam)

Ifanelekile ukusetyenziswa kwiinyikima kunye nonxweme

Kutheni le nto ii-hot-rolled U-type piles zilawula?

Iinqwaba zamaphepha ezigoqwe ngobushushu ze-U zibonelela:

Imodyuli yecandelo eliphezulu

Ukuqina okungcono kwe-interlock

Ukuthembeka okukhulu kwesakhiwo

Ubomi benkonzo obude kunye nokusetyenziswa ngcono

Iinqwaba ze-U ezibunjwe ngobandayo zibonakala kwiiprojekthi ezikhaphukhaphu kodwa azixhaphakanga kakhulu kwiziseko zophuhliso ezinkulu.

Iinkcukacha kunye nobukhulu obusetyenziswa kakhulu

●Ububanzi obudumileyo

Ezi zibane zilandelayo zithengwa kakhulu kulo lonke elaseMzantsi-mpuma Asia:

Ububanzi beNqwaba yePhepha	Amanqaku okusetyenziswa
400 mm	Usetyenziso olulula ukuya koluphakathi, oluguquguqukayo kwimilambo emincinci nakwimisebenzi yexeshana
600 mm (Uhlobo oluQhelekileyo)	Isetyenziswa kakhulu kwiiprojekthi ezinkulu zaselwandle, zezibuko, nezezindlu
750 mm	Izakhiwo ezinzima ezifuna i-section modulus ephezulu

● Uluhlu loBunzima obuQhelekileyo

5–16 mm kuxhomekeke kwimodeli kunye neemfuno zesakhiwo
Iindlela ezityebileyo (10–14 mm) ziqhelekile kwimisebenzi yonxweme kunye neyezibuko.

● Ubude

Impahla eqhelekileyo: 6 m, 9 m, 12 m

Ukuqengqeleka okusekelwe kwiprojekthi: 15–20+ m
Iinqwaba ezinde zinciphisa amalungu adibeneyo kwaye ziphucula uzinzo lwesakhiwo.

Unyango Lomphezulu kunye noKhuselo Lokugqwala

Imozulu eshushu nefumileyo eMzantsi-mpuma Asia ifuna amanyathelo athembekileyo okulwa nokugqwala. Olu nyango lulandelayo lusetyenziswa kakhulu:

● Ukucoca nge-Hot-Dip

Ukhuseleko olugqwesileyo kumanzi anetyuwa

Ifanelekile kwizakhiwo zaselwandle ezihlala ixesha elide

● Iingubo ze-Epoxy / i-Coal-Tar Epoxy
