Ungayikhetha Kanjani Inqwaba Yeshidi Eligoqekile Elibandayo Elifanele Yamaphrojekthi?
Kumaphrojekthi afana nokusekelwa kwesisekelo esijulile, amaphrojekthi okulondolozwa kwamanzi, kanye nokuvikelwa kogu, ukukhethwa kwezinqwaba zamaphepha ezifanele kuthinta ngqo ukuphepha kwephrojekthi, ukusebenza kahle kokwakhiwa, kanye nezindleko zephrojekthi. Uma ubhekene nezinhlobo ezahlukene zemikhiqizo yezinqwaba zamaphepha emakethe, ungenza kanjani isinqumo esifanele? Lesi sihloko sihlaziya izici ezibalulekile zokukhetha ngokuqala ngezici zobuchwepheshe zeInqwaba Yeshidi Eligoqiwe Elibandayoimikhiqizo (ye-CRT).
Ukuqonda Izinzuzo Zobuchwepheshe Zenqwaba Yeshidi Eligoqekile Elibandayo Ama-sheet pile anomumo we-OZ aqoqekile ayingxenye ebalulekile yezinhlelo zodonga lwezinqwaba ezihlanganisiwe, ezivame ukusetshenziswa kanye namapayipi e-SSAW ahlanganisiwe ajikelezayo kumaphrojekthi amakhulu okusekela. Inqubo yawo yokukhiqiza ihlukile: i-billet yensimbi iqala ngokugoqeka ngokushisa ibe ama-coil, kodwa ayikhiwanga ngokuqondile engxenyeni yokugcina enomumo we-U noma u-Z; ngemva kokuba i-coil yensimbi ipholile ngokwemvelo, bese igoqeka njalo ekamelweni lokushisa yiyunithi yokugoqa ebandayo ukuze ibumbe kancane kancane ingxenye eqondile enomumo we-Z. Le nqubo enezinyathelo ezimbili "eshisayo bese kubanda" ivumela umkhiqizo ukuthi ugcine ukuqina okuhle kwezinto eziyisisekelo ezigoqekile ngokushisa ngenkathi kufezwa ukunemba okuphezulu kokugoqa okubandayo.
Isici Sokukhetha Okubalulekile 1: Izidingo Zephrojekthi kanye neModulus Yesigaba
Uma ukhetha i-Cold Rolled Sheet Pile, okubalulekile okufanele ukucabangele ukufana phakathi kwe-section modulus kanye nezidingo zomklamo. Imikhiqizo eyenziwe ngomumo obandayo inikeza izinketho eziningi zesigaba, okuvumela onjiniyela ukuthi bakhethe imininingwane eseduze nemingcele yomklamo ngaphandle kokukhulisa isisindo kakhulu. Uma kuqhathaniswa nezinqwaba zamaphepha ezigoqwe ngokushisa, ukwakheka okuxhumene kwezinqwaba zamaphepha ezigoqwe ngokushisa kuvumela ukulungiswa okuphezulu kwe-engeli yokujikeleza kwama-degrees angu-25, okudlula kakhulu ububanzi bokujikeleza kwama-degrees angu-7-10 bemikhiqizo egoqwe ngokushisa, okunikeza izinzuzo ezibalulekile ezimweni eziyinkimbinkimbi njenge-cofferdams egobile kanye nemigodi yesisekelo esiyindilinga.
Isici Esiyinhloko Sokukhetha 2: Isikhathi Sokulethwa Nezindleko Zokuhamba
NgesikhathiIntengo Yenqwaba YeshidiKubalulekile ukucatshangelwa, izindleko zizonke kufanele zinikezwe ukunakwa okwengeziwe. Izinqwaba zamaphepha ezibandayo zikhiqizwa ngamaqoqo amakhulu anezinhlelo zokugoqa eziguquguqukayo, ngomjikelezo wokukhiqiza ojwayelekile wamasonto amabili kuphela, okunciphisa kakhulu isikhathi sokulinda iphrojekthi. Ngaphezu kwalokho, ngenxa yokusatshalaliswa kabanzi kwabahlinzeki bezinqwaba zamaphepha, abathengi banethuba elikhulu lokuthola abahlinzeki abaseduze, okunciphisa kakhulu izindleko zokuhamba ibanga elide. "Ukutholakala kalula" kwezinto zokwakha ngokwakho kuyinzuzo enkulu yezindleko.
Isici Sesithathu Sokukhetha Okubalulekile: Ubuchwepheshe Bomhlinzeki
Ukukhetha okuthembekileabahlinzeki benqwaba yeshidikusho ukuthola hhayi imikhiqizo kuphela, kodwa nokusekelwa kobuchwepheshe kanye neziqinisekiso zokuhlinzeka. Abaphakeli abangochwepheshe bangancoma uhlobo lwenqwaba olufanele kakhulu kanye nemininingwane ngokusekelwe ezimweni zejiyoloji yephrojekthi kanye nezinhlelo zokwakha, futhi banikeze izinsizakalo zokucubungula ezingeziwe njengokupenda nokubhoboza. Ukubambisana nabaphakeli abanolwazi lwamashumi eminyaka embonini kuqinisekisa inqubo ebushelelezi kusukela ekubonisaneni ngokukhetha kuya ekulethweni endaweni.
Ukulinganisela ukusebenza kobuchwepheshe kanye nezindleko zezomnotho kubalulekile ekukhetheni izinqwaba zamaphepha. Izinqwaba zamaphepha ezigoqiwe ezibandayo, kanye nokuguquguquka kwazo kwenqubo, izinzuzo zezindleko, kanye nokuzivumelanisa nokwakhiwa, seziba ukukhetha okujwayelekile kwenani elikhulayo lamaphrojekthi obunjiniyela. Ukukhetha abahlinzeki bezinqwaba zamaphepha abanolwazi kuyisiqinisekiso esinamandla sokuhumusha lezi zinzuzo zibe yimpumelelo yephrojekthi.
