Uyini Umehluko Phakathi Kwezinqwaba Zensimbi Ezigoqiwe Ezishisayo Nezinqwaba Zensimbi Ezigoqiwe Ezibandayo

Emkhakheni wobunjiniyela bezakhiwo kanye nokwakha,Izinqwaba Zeshidi Lensimbi(okuvame ukubizwa ngokuthiukunqwabelanisa amashidi) sekuyisikhathi eside kuyitshe lesisekelo samaphrojekthi adinga ukugcinwa komhlaba okuthembekile, ukumelana namanzi, kanye nokusekelwa kwesakhiwo—kusukela ekuqinisweni kogu lomfula kanye nokuvikelwa kogu kuya ekumbiweni kwesisekelo kanye nezithiyo zokwakha zesikhashana. Kodwa-ke, akuzona zonke izinqwaba zensimbi ezidalwe zilingana: izinqubo ezimbili eziyinhloko zokukhiqiza—ukugoqa okushisayo kanye nokwakha okubandayo—ukukhiqiza imikhiqizo ehlukile, izinqwaba zensimbi ezigoqiwe ezishisayo kanye nezinqwaba zensimbi ezigoqiwe ezibandayo, ngayinye inezici ezihlukile ezenza zifanelekele izinhlelo ezithile. Ukuqonda umehluko wazo kubalulekile konjiniyela, osonkontileka, kanye nabaphathi bephrojekthi ukuze benze izinqumo ezingabizi kakhulu neziqhutshwa ukusebenza.

Izinhlobo ezimbili zezinqubo zokukhiqiza inqwaba yensimbi

Izinqubo zokukhiqiza zezinhlobo ezimbili zokufaka amashidi zibeka isisekelo sezakhiwo zazo ezihlukene.Izinqwaba Zeshidi Zensimbi Ezigoqiwe Ezishisayozikhiqizwa ngokushisa ama-billet ensimbi kumazinga okushisa aphezulu kakhulu (ngokuvamile angaphezu kuka-1,000°C) kuze kube yilapho insimbi iguquguquka, bese iyidlulisa ochungechungeni lwama-roller ukuze iyibumbe ibe amaphrofayili axhumene (njengohlobo lwe-U, uhlobo lwe-Z, noma i-straight web) achaza ukufakwa kwamaphepha. Le nqubo yokushisa okuphezulu ivumela izingxenye eziyinkimbinkimbi neziqinile futhi iqinisekisa ubuningi bezinto ezifanayo, njengoba ukushisa kuqeda ukucindezeleka kwangaphakathi ensimbini. Ngokuphambene nalokho,Amaqoqo Eshidi Lensimbi Eligoqiwe Elibunjiwe Elibandayozenziwe ngamakhoyili ensimbi asikiwe ngaphambilini, ayisicaba akhiwe ngamaphrofayili axhumene kusetshenziswa ama-roller abandayo—akukho ukushisa okukhulu okusetshenziswayo ngesikhathi sokwakheka. Inqubo yokugoqa ebandayo incike ekuguquguqukeni kwensimbi ekushiseni kwegumbi, okwenza ibe yindawo ekahle yokukhiqiza amaphrofayili alula futhi ajwayelekile, yize ingase ilethe ukucindezeleka okuncane kwangaphakathi okudinga ukucutshungulwa ngemuva (njengokunamathisela) kwezinye izinhlelo zokusebenza ezithwala umthwalo omkhulu.

Ukusebenza kanye nezici zesakhiwo zezinhlobo ezimbili zezinqwaba zensimbi

Ukusebenza kanye nezici zesakhiwo zihlukanisa lezi zinhlobo ezimbili. Izinqwaba zamaphepha ezigoqekile ezishisayo zinikeza amandla nokuqina okumangalisayo: isakhiwo sazo esigoqekile esishisayo sinikeza amandla aphezulu okubamba, amandla okukhiqiza, kanye nokumelana nomthelela, okwenza zibe zilungele amaphrojekthi anzima, esikhathi eside. Isibonelo, izinqwaba zamaphepha ezigoqekile ezishisayo zivame ukuthandwa kumaphrojekthi okumba ajulile (lapho izinqwaba zamaphepha kufanele zibhekane nokucindezela okukhulu komhlaba) noma izakhiwo zokuvikela ezihlala njalo zasogwini (ezivezwe esimweni sezulu esibi kanye nokugqwala kwamanzi olwandle). Uma ziphathwa ngesembozo (njenge-epoxy noma i-zinc), izinqwaba zamaphepha ezigoqekile ezishisayo nazo zinikeza ukumelana okuthuthukisiwe kokugqwala, njengoba isakhiwo sezinto ezifanayo siqinisekisa ukunamathela okufanayo kwengqimba yokuvikela. Izinqwaba zamaphepha ezibandayo, ngakolunye uhlangothi, zilula futhi zingabizi kakhulu ekusetshenzisweni kwesikhashana noma komthwalo ophakathi. Isisindo sazo esiphansi senza kube lula ukuthutha nokufaka—kudinga imishini encane kanye nomsebenzi—okwenza zibe zilungele ukwesekwa kwesakhiwo sesikhashana, izindonga zesikhashana zezikhukhula, noma amaphrojekthi angaphansi kwezindlu zokuhlala, lapho amandla amakhulu okuthwala umthwalo akuyona imfuneko eyinhloko. Nakuba amandla azo ephansi kunezinye izindlela zazo ezishiswa ngokushisa, intuthuko yakamuva kwezobuchwepheshe bokwakha amakhaza (njengezinsimbi zensimbi ezinamandla aphezulu) yandise ukusetshenziswa kwazo ezakhiweni ezihlala isikhathi eside.

Izindleko kanye nokutholakala kwezinhlobo ezimbili zezinqwaba zensimbi

Izindleko nokutholakala kwazo nakho kuyizinto ezibalulekile ekukhetheni phakathi kwalezi ezimbili. Ama-Cold Formed Rolled Steel Sheet Piles ngokuvamile anezindleko eziphansi kusengaphambili, njengoba inqubo yokugoqa ebandayo igcina amandla amaningi, idinga imishini ekhethekile kakhulu, futhi ikhiqiza imfucuza encane yezinto ezibonakalayo uma kuqhathaniswa nokugoqa okushisayo. Atholakala kalula futhi ngobukhulu obujwayelekile, anezikhathi ezimfushane zokuhola zokukhiqiza—ezibalulekile kumaphrojekthi anezikhathi eziqinile. Ama-Hot Rolled Steel Sheet Piles, ngokuphambene, anezindleko zokukhiqiza eziphakeme ngenxa yenqubo yokushisa edinga amandla amaningi kanye nesidingo semishini yokugoqa eyinkimbinkimbi kakhulu. Amaphrofayili enziwe ngokwezifiso (aklanyelwe izidingo zephrojekthi ezihlukile) nawo aneza izindleko zawo nesikhathi sokuhola. Kodwa-ke, ukuqina kwawo isikhathi eside kuvame ukuqeda ukutshalwa kwezimali okuphezulu kokuqala: ezakhiweni ezihlala njalo, Ama-Hot Rolled Steel Sheet Piles adinga ukulungiswa okuncane futhi anempilo yesevisi ende, okunciphisa izindleko zomjikelezo wokuphila ngokuhamba kwesikhathi.

Izinzuzo zabo

Ngamafuphi, zombili izinqwaba zamaphepha ezigoqwe ngokushisa kanye nezibandayo zidlala indima ebalulekile ekwakheni kwesimanje, kodwa umehluko wazo ekukhiqizeni, ekusebenzeni, kanye nezindleko zenza zifaneleke kakhulu ekusetshenzisweni okuthile. Izinqwaba zamaphepha ezigoqwe ngokushisa zaziwa ngamandla azo, ukuqina, kanye nokufaneleka kwazo ekusetshenzisweni okuhlala njalo, okunzima, kuyilapho izinqwaba zamaphepha ezibandayo zinikeza ukusebenza kahle kwezindleko, ukulula kokufakwa, kanye nokuguquguquka, okwenza zifaneleke kumaphrojekthi esikhashana noma aphakathi nendawo. Njengoba isidingo sokwakha okusimeme futhi okusebenzayo siqhubeka nokukhula, ochwepheshe bezimboni babikezela ukusungulwa okuqhubekayo kuzo zombili izinqubo, kusukela kuma-alloy anamandla aphezulu akhiwe ngokubandayo athuthukisiwe kuya kubuchwepheshe bokugoqwa ngokushisa obusebenzisa amandla amaningi, okwandisa kakhulu ukuguquguquka kwezinqwaba zamaphepha kanye nezixazululo zezinqwaba zamaphepha emhlabeni jikelele.
