Nguwuphi Umahluko phakathi kweemfumba zeShiti eliqengqelekayo eliHolisiweyo kunye neMigquma yeShiti eliQonxiweyo elibandayo

Kwinkalo yobunjineli boluntu kunye nokwakha,Iimfumba zeShiti leNsimbi(idla ngokubizwa ngokubaukufumba kwephepha) kudala isisiseko seeprojekthi ezifuna ugcino lomhlaba oluthembekileyo, ukuxhathisa kwamanzi, kunye nenkxaso yesakhiwo-ukusuka ekomelezeni komlambo kunye nokhuseleko lonxweme ukuya ekugrunjweni komgangatho ongaphantsi kunye nemiqobo yokwakha yethutyana. Nangona kunjalo, ayizizo zonke iiPiles ze-Steel Sheet ezenziwe ngokulinganayo: iinkqubo ezimbini eziphambili zokuvelisa-i-hot rolling kunye ne-cold form-zivelisa iimveliso ezihlukeneyo, i-Hot Rolled Steel Sheet Piles kunye ne-Cold Formed Rolled Steel Sheet Piles, nganye ineempawu ezizodwa ezenza ukuba zilungele izicelo ezithile. Ukuqonda umahluko wabo kubalulekile kwiinjineli, iikontraka, kunye nabaphathi beprojekthi ukwenza izigqibo ezingabizi kakhulu, eziqhutywa yintsebenzo.

Iintlobo ezimbini zeenkqubo zokuvelisa inqwaba yentsimbi

Iinkqubo zokwenziwa kweentlobo ezimbini zokufakwa kwamaphepha zibeka isiseko seempawu zabo ezahlukeneyo.Iimfumba zeshiti lentsimbi eliqengqelekayoziveliswa ngokufudumeza iibhilithi zentsimbi ukuya kumaqondo obushushu aphezulu kakhulu (ngokuqhelekileyo ngaphezu kwe-1,000 ° C) de isinyithi sibe sithambileyo, emva koko sidlule kuluhlu lwee-rollers ukuze sibumbe kwiiprofayili ezidibeneyo (ezifana nohlobo lwe-U, uhlobo lwe-Z, okanye iwebhu ethe ngqo) echaza i-sheet piling. Le nkqubo yobushushu obuphezulu ivumela ukuba kube nzima, ukuqina kwe-cross-sections kunye nokuqinisekisa ukuxinana kwezinto ezifanayo, njengoko ukushisa kuphelisa uxinzelelo lwangaphakathi kwintsimbi. Okuchasene,Iimfumba zeShiti eliQonxiweyo elibandayozenziwe kwi-pre-cut, iikhoyili zetsimbi ezisicaba ezibunjwe kwiiprofayili ezidibeneyo zisebenzisa ii-roller ezibandayo-akukho bushushu obugqithisileyo obusetyenziswayo ngexesha lokubumba. Inkqubo yokuqengqeleka ebandayo ixhomekeke kwi-ductility yensimbi kwiqondo lokushisa, okwenza kube yinto efanelekileyo yokuvelisa iiprofayili ezilula, ezisemgangathweni, nangona zinokuzisa uxinzelelo oluncinci lwangaphakathi olufuna ukucutshungulwa kwangemva (njenge-annealing) kwizicelo ezithile zomthwalo ophezulu.

Ukusebenza kunye neempawu zesakhiwo seentlobo ezimbini zeemfumba zentsimbi

Ukusebenza kunye neempawu zesakhiwo ziyahlula ngakumbi ezi ndidi zimbini. Iimfumba zamaphepha aqengqelekayo ashushu zinika amandla akhethekileyo kunye nokuqina: ubume bawo obushushu bugqithisa amandla aphezulu, ukomelela kwesivuno, kunye nokumelana neempembelelo, kubenza balungele umsebenzi onzima, iiprojekthi zexesha elide. Umzekelo, iingqumba zamashiti aqengqelekayo ashushu zikholisa ukukhethwa kwiiprojekthi zokwembiwa nzulu (apho iingqumba zamashiti kufuneka zimelane noxinzelelo olumandla lomhlaba) okanye izakhiwo ezisisigxina zokhuselo lonxweme (ezichanabeke kwimozulu embi kunye nomhlwa kwamanzi olwandle). Xa uphathwa nge-coating (efana ne-epoxy okanye i-zinc), i-hot-rolled sheet sheets iphinda ibonelele ukuxhathisa ukuphuculwa kwe-corrosion, njengoko i-uniform material structure iqinisekisa ukunamathela okufanayo kwinqanaba elikhuselayo. Iimfumba zamaphepha ezipholileyo, kwelinye icala, zikhaphukhaphu kwaye zineendleko eziphezulu kwizicelo zomthwalo wexeshana okanye ophakathi. Ubunzima babo obuphantsi benza lula ukuthutha kunye nofakelo-oludinga izixhobo ezincinci kunye nomsebenzi-obenza ukuba balungele ukuxhaswa kwesakhiwo sexesha elifutshane, iindonga zexeshana, okanye iiprojekthi eziphantsi kwendawo yokuhlala, apho umthamo ogqithisayo wokuthwala imithwalo ayiyona imfuneko ephambili. Ngelixa amandla abo ephantsi kunezinye iindlela zabo ezishushu, inkqubela phambili yamva nje kwithekhnoloji yokwenza ukubanda (ezifana ne-alloys yensimbi ephezulu) iye yandisa ukusetyenziswa kwayo kwizakhiwo ezisisigxina.

Iindleko kunye nokufumaneka kweentlobo ezimbini zeentsimbi zentsimbi

Iindleko kunye nokufumaneka zizinto eziphambili ekukhetheni phakathi kwezi zibini. I-Cold Formed Steel Sheet Piles ngokubanzi inexabiso eliphantsi elisezantsi, njengoko inkqubo yokuqengqeleka ebandayo inamandla angakumbi, ifuna izixhobo ezikhethekileyo, kwaye ivelisa inkunkuma yezinto ezincinci xa kuthelekiswa nokuqengqeleka okushushu. Zikwafumaneka ngokulula kubungakanani obuqhelekileyo, kunye namaxesha amafutshane okukhokelela kwimveliso-ibaluleke kakhulu kwiiprojekthi ezineshedyuli eziqinileyo. I-Hot Rolled Steel Sheet Piles, ngokuchaseneyo, ineendleko eziphezulu zemveliso ngenxa yenkqubo yokufudumeza ngamandla kunye nesidingo soomatshini abaqengqelekayo abanzima. Iiprofayili eziqhelekileyo (ezenzelwe iimfuno zeprojekthi eyodwa) nazo zongeza kwiindleko zazo kunye nexesha lokukhokela. Nangona kunjalo, ukuqina kwabo kwexesha elide kudla ngokunciphisa utyalo-mali oluphezulu oluphezulu: kwizakhiwo ezisisigxina, i-Hot Rolled Steel Sheet Piles ifuna ukugcinwa okuncinci kwaye ibe nobomi obude benkonzo, ukunciphisa iindleko zobomi ngokuhamba kwexesha.

Izibonelelo zabo

Isishwankathelo, zombini iimfumba zeshiti ezishushu kunye nezibandayo zidlala indima ebalulekileyo kulwakhiwo lwangoku, kodwa ukungafani kwabo kwimveliso, ukusebenza kunye neendleko kubenza bafaneleke ngakumbi kwizicelo ezithile. Iimfumba zeshiti ezishushu ziyaziwa ngamandla azo, ukuqina, kunye nokufaneleka kwezicelo ezisisigxina, ezinzima, ngelixa iimfumba zamaphepha ezibandayo zibonelela ngeendleko-ukusebenza, ukufakela ngokulula, kunye nokuguquguquka, okwenza ukuba zilungele iiprojekthi zexeshana okanye eziphakathi. Njengoko imfuno yolwakhiwo oluzinzileyo nolusebenzayo luqhubeka nokukhula, iingcali zoshishino ziqikelela ukuveliswa kwezinto ezintsha kuzo zombini iinkqubo, ukusuka kwi-alloys ephuculweyo eyenziwe ngokubanda ephezulu ukuya kwi-eneji eyongayo yetekhnoloji yokuqengqeleka eshushu, ukwandisa ngakumbi ukuguquguquka kweemfumba zeshiti kunye nezisombululo zemfumba yamaphepha kwihlabathi liphela.
