Izinqwaba zamashidi ensimbi, njengezinto ezisekelayo zesakhiwo ezihlanganisa amandla nokuvumelana nezimo, zidlala indima engenakuthathelwa indawo kumaphrojekthi okonga amanzi, ukwakhiwa kokumba kwesisekelo esijulile, ukwakhiwa kwechweba, neminye imikhakha. Izinhlobo zabo ezihlukahlukene, izinqubo zokukhiqiza eziyinkimbinkimbi, kanye nokusetshenziswa okubanzi komhlaba wonke kuzenza zibe izinto ezibalulekile zokuqinisekisa ukuphepha kanye nokwenza ngcono ukusebenza kahle ekwakheni. Lesi sihloko sizohlinzeka ngohlaziyo oluningiliziwe lwezinhlobo eziwumongo zezinqwaba zamashidi ensimbi, umehluko wazo, izindlela zokukhiqiza ezijwayelekile, nosayizi abavamile nokucaciswa, okuhlinzeka ngereferensi ebanzi yabasebenzi bokwakha nabathengi.
Izinqwaba zamashidi ensimbizihlukaniswa ngomumo we-cross-sectional. Izinqwaba zamashidi ensimbi ohlobo lwe-Z- kanye no-U yizona ezikhethwa kakhulu kwezobunjiniyela ngenxa yohlu olubanzi lwezinhlelo zokusebenza kanye nezinzuzo zokusebenza ezivelele. Kodwa-ke, kunomehluko omkhulu phakathi kwalezi zinhlobo ezimbili ngokuya ngesakhiwo, ukusebenza, kanye nezimo zohlelo lokusebenza:
Izinqwaba zamashidi ensimbi amise okwe-U: Afaka isakhiwo esivulekile esifana nesiteshi esinamaphethelo akhiyayo ukuze alingane, okuzivumela ukuthi zivumelane nezimfuneko zokuguquguquka okukhulu kumaphrojekthi wobunjiniyela. Izakhiwo zabo ezinhle kakhulu zokuguquguquka zizenza zisetshenziswe kabanzi kumaphrojekthi wamanzi amaningi aphezulu (njengokulawulwa kwemifula kanye nokuqiniswa kwedamu lamanzi) kanye nokusekelwa komgodi wesisekelo ojulile (njengokwakhiwa ngaphansi komhlaba ezakhiweni eziphakeme). Njengamanje ziwuhlobo olusetshenziswa kakhulu lwenqwaba yeshidi lensimbi emakethe.
Izinqwaba zeshidi lensimbi ezimise okuka-Z: Afaka isigaba esiphambanayo esivaliwe, esimazombezombe esinamapuleti ensimbi aminyene nhlangothi zombili, okuholela kumodulus yesigaba esiphezulu kanye nokuqina okuphezulu kwe-flexural. Lokhu kuvumela ukulawula okunembile kokuguqulwa kobunjiniyela futhi kulungele amaphrojekthi aphezulu anezidingo eziqinile zokulawula ukuwohloka (njengemigodi yesisekelo sefekthri enembile kanye nokwakhiwa kwesisekelo sebhuloho elikhulu). Kodwa-ke, ngenxa yobunkimbinkimbi bobuchwepheshe bokugoqeka kwe-asymmetric, yizinkampani ezine kuphela emhlabeni wonke ezinomthamo wokukhiqiza, okwenza lolu hlobo lwenqwaba yamashidi lube yindlala kakhulu.
Inqubo yokukhiqiza izinqwaba zeshidi lensimbi ithinta ngokuqondile ukusebenza kwabo kanye nezicelo ezisebenzayo. Njengamanje, ukugoqa okushisayo nokugoba okubandayo yizindlela ezimbili eziyinhloko ezisetshenziswa embonini, ngayinye igxile kakhulu ezinqubweni zokukhiqiza, izici zomkhiqizo, kanye nokuma kwesicelo:
Izinqwaba zeshidi lensimbi eligoqelwe ngokushisayoenziwe ngamabhilidi ensimbi, ashiselwe emazingeni okushisa aphezulu, bese egoqwa abe yisimo kusetshenziswa imishini ekhethekile. Umkhiqizo oqediwe unikeza ukunemba okuphezulu kokukhiya namandla aphezulu, okuwenza ube ngumkhiqizo ohamba phambili kumaphrojekthi wobunjiniyela. I-Royal Steel Group isebenzisa inqubo ye-tandem eqhubekayo yokugoqa ukuze inikeze izinqwaba ezimise okwe-U ezinobubanzi obungu-400-900mm kanye nezinqwaba ezimise okwe-Z ezinobubanzi obungu-500-850mm. Imikhiqizo yabo yenze kahle kakhulu emhubheni we-Shenzhen-Zhongshan, okwenza bathole idumela "lokumisa izinqwaba" kumnikazi wephrojekthi, okubonisa ngokugcwele ukwethembeka kwenqubo yokugoqa okushisayo.
Izinqwaba zamashidi ensimbi ezakhiwe ngokubandayoakhiwe ngendlela yokushisa ekamelweni, aqede isidingo sokwelashwa okunokushisa okuphezulu. Lokhu kubangela ukuphela kwendawo ebushelelezi kanye nokumelana nokugqwala okungcono okungama-30% -50% kunenqwaba egoqwe ngokushisayo. Afanele ukusetshenziswa ezindaweni ezinomswakama, ezingasogwini, nezithandwa ukugqwala (isb, ukwakhiwa komgodi wesisekelo). Kodwa-ke, ngenxa yemikhawulo yenqubo yokwakhiwa kwezinga lokushisa kwegumbi, ukuqina kwabo kwesigaba esiphambanayo kubuthakathaka. Ngokuyinhloko zisetshenziswa njengempahla eyengeziwe, ngokuhambisana nezinqwaba ezigoqelwe ngokushisayo ukuze kuthuthukiswe izindleko zephrojekthi nokusebenza.
Izinhlobo ezahlukene zezinqwaba zeshidi lensimbi zinezindinganiso ezicacile ze-dimensional. Ukuthengwa kwephrojekthi kufanele kucabangele izidingo ezithile (ezifana nokujula kokumba kanye nobukhulu bomthwalo) ukuze ukhethe ukucaciswa okufanele. Okulandelayo izilinganiso ezivamile zezinhlobo ezimbili ezivamile zamapulangwe ensimbi:
Izinqwaba zeshidi lensimbi ezimise okwe-U: Ukucaciswa okujwayelekile kuvame ukuthi yi-SP-U 400×170×15.5, enobubanzi obusuka ku-400-600mm, ugqinsi kusuka ku-8-16mm, nobude obungu-6m, 9m, no-12m. Ngezidingo ezikhethekile ezifana nokumbiwa okukhulu, okujulile, ezinye izinqwaba ezishisiwe ezimise okwe-U zingenziwa ngokwezifiso zibe ubude obufika ku-33m ukuze zihlangabezane nezidingo ezijulile zokusekela.
Izinqwaba zamashidi ensimbi anomumo ongu-Z: Ngenxa yemikhawulo yenqubo yokukhiqiza, ubukhulu bulinganiselwe ngokuqhathaniswa, ezinobude obunqamulelanayo obusuka ku-800-2000mm nobukhulu obusuka ku-8-30mm. Ubude obujwayelekile ngokuvamile buphakathi kuka-15-20m. Ukucaciswa okude kudinga ukubonisana kwangaphambili nomkhiqizi ukuze kuqinisekiswe ukwenzeka kwenqubo.
Kusukela emachwebeni aseNingizimu-mpumalanga ye-Asia kuya ezindaweni zokugcina amanzi eNyakatho Melika, izinqwaba zamashidi ensimbi, ngokuguquguquka kwazo, ziye zasetshenziswa kumaphrojekthi ahlukahlukene emhlabeni jikelele. Okulandelayo yizibonelo ezintathu ezijwayelekile ezivela kumakhasimende ethu, abonisa inani lawo elisebenzayo:
Iphrojekthi Yokunwetshwa Kwechweba Lase-Philippine: Ngesikhathi sokwandiswa kwechweba e-Philippines, usongo lokukhuphuka kweziphepho okubangelwa iziphepho ezivame ukuvela. Umnyango wethu wezobuchwepheshe uncome ukusetshenziswa kwezinqwaba zensimbi ezigoqelwe ezimise okwe-U ze-cofferdam. Indlela yabo yokukhiya eqinile imelane ngempumelelo nomthelela wesiphepho, iqinisekisa ukuphepha nenqubekela phambili yokwakhiwa kwechweba.
Iphrojekthi yokubuyisela ihabhu yokonga amanzi e-Canadian: Ngenxa yobusika obubandayo endaweni yehabhu, inhlabathi ijwayele ukuguquguquka ngenxa yemijikelezo yokuqhwaza, edinga ukuzinza okuphezulu kakhulu. Umnyango wethu wezobuchwepheshe uncome ukusetshenziswa kwezinqwaba zeshidi elishisayo eligoqelwe elingu-Z ukuze kuqiniswe. Amandla abo okugoba aphezulu angamelana nokushintshashintsha kokucindezeleka kwenhlabathi, okuqinisekisa ukusebenza okuzinzile kwesikhathi eside kwehabhu lokonga amanzi.
Iphrojekthi yokwakhiwa kwesakhiwo sensimbi e-Guyana: Ngesikhathi sokwakhiwa komgodi wesisekelo, iphrojekthi yayidinga ukulawulwa okuqinile kokuguqulwa kwemithambeka ukuze kuqinisekiswe ukuphepha kwesakhiwo esikhulu. Usonkontileka ushintshele ezinqwaba zamashidi ensimbi awakheke ngendlela ebandayo ukuze aqinise isisekelo somgodi wokuthambeka, ehlanganisa ukumelana nokugqwala kwazo nokuvumelana kwazo nemvelo eswakeme yendawo ukuze iqedele iphrojekthi ngempumelelo.
Kusukela emachwebeni aseNingizimu-mpumalanga ye-Asia kuya ezindaweni zokugcina amanzi eNyakatho Melika, izinqwaba zamashidi ensimbi, ngokuguquguquka kwazo, ziye zasetshenziswa kumaphrojekthi ahlukahlukene emhlabeni jikelele. Okulandelayo yizibonelo ezintathu ezijwayelekile ezivela kumakhasimende ethu, abonisa inani lawo elisebenzayo:
Iphrojekthi Yokunwetshwa Kwechweba lase-Philippine:Phakathi nokwandiswa kwechweba ePhilippines, usongo lokuqubuka kweziphepho ezibangelwa iziphepho ezivame ukuvela. Umnyango wethu wezobuchwepheshe uncome ukusetshenziswa kwezinqwaba zensimbi ezigoqelwe ezimise okwe-U ze-cofferdam. Indlela yabo yokukhiya eqinile imelane ngempumelelo nomthelela wesiphepho, iqinisekisa ukuphepha nenqubekela phambili yokwakhiwa kwechweba.
Iphrojekthi yokubuyisela indawo yokonga amanzi yaseCanada:Ngenxa yobusika obubandayo endaweni yesikhungo, inhlabathi ijwayele ukuguquguquka ngenxa yemijikelezo yokuncibilika kweqhwa, edinga ukuzinza okuphezulu kakhulu. Umnyango wethu wezobuchwepheshe uncome ukusetshenziswa kwezinqwaba zeshidi elishisayo eligoqelwe elingu-Z ukuze kuqiniswe. Amandla abo okugoba aphezulu angamelana nokushintshashintsha kokucindezeleka kwenhlabathi, okuqinisekisa ukusebenza okuzinzile kwesikhathi eside kwehabhu lokonga amanzi.
Iphrojekthi yokwakha isakhiwo sensimbi eGuyana:Ngesikhathi sokwakhiwa komgodi wesisekelo, iphrojekthi yayidinga ukulawulwa okuqinile kokuguqulwa kwemithambeka ukuze kuqinisekiswe ukuphepha kwesakhiwo esikhulu. Usonkontileka ushintshele ezinqwaba zamashidi ensimbi awakheke ngendlela ebandayo ukuze aqinise isisekelo somgodi wokuthambeka, ehlanganisa ukumelana nokugqwala kwazo nokuvumelana kwazo nemvelo eswakeme yendawo ukuze iqedele iphrojekthi ngempumelelo.
Kungakhathaliseki ukuthi iphrojekthi yokonga amanzi, iphrojekthi yembobo, noma ukwesekwa komgodi wesisekelo sokwakha, ukukhetha uhlobo olufanele lwenqwaba yeshidi lensimbi, inqubo, kanye nokucaciswa kwayo kubalulekile ukuze kuqinisekiswe ikhwalithi yephrojekthi.
