Ungayikhetha njani iNqwaba yePhepha eQokelelweyo eBandayo efanelekileyo kwiiprojekthi?
Kwiiprojekthi ezinje ngokuxhasa umngxuma wesiseko esinzulu, iiprojekthi zokugcina amanzi, kunye nokukhuselwa konxweme, ukukhethwa kweenqwaba zamaphepha ezifanelekileyo kuchaphazela ngqo ukhuseleko lweprojekthi, ukusebenza kakuhle kolwakhiwo, kunye neendleko zeprojekthi. Xa ujongene neentlobo ezahlukeneyo zeemveliso zeenqwaba zamaphepha kwimarike, ungenza njani isigqibo esifanelekileyo? Eli nqaku lihlalutya izinto eziphambili zokukhetha ngokuqala ngeempawu zobuchwepheshe zeInqwaba yePhepha eliSongiweyo elibandayoiimveliso (ze-CRT).
Ukuqonda Iingenelo Zetekhnoloji Zenqwaba Yephepha Eliqengqelekayo Elibandayo Iinqwaba zephepha eziqengqelekayo ezibandayo ezimile okwe-OZ ziyinxalenye ebalulekileyo yeenkqubo zodonga lweenqwaba ezihlanganisiweyo, ezisetyenziswa rhoqo kunye neepayipi ezihlanganisiweyo ze-SSAW kwiprojekthi ezinkulu zokuxhasa. Inkqubo yazo yokuvelisa ihlukile: i-billet yentsimbi iqala ngokuqengqeleka ibe ziikhoyili, kodwa ayidalwanga ngokuthe ngqo kwicandelo lokugqibela elimile okwe-U okanye elingu-Z; emva kokuba ikhoyili yentsimbi ipholile ngokwendalo, emva koko iqengqeleka rhoqo kubushushu begumbi yiyunithi yokugoba ebandayo ukuze ibumbe kancinci kancinci icandelo elinqamlezileyo elingu-Z. Le nkqubo "eshushu emva koko ibanda" inamanyathelo amabini ivumela imveliso ukuba igcine ukuqina okugqwesileyo kwezinto ezisisiseko eziqengqelekayo ezishushu ngelixa ifezekisa ukuchaneka okuphezulu kokugoba okubandayo.
Inqaku eliPhambili loKhetho 1: Iimfuno zeProjekthi kunye neModulus yeCandelo
Xa ukhetha iCold Rolled Sheet Pile, into ephambili ekufuneka iqwalaselwe kukuhambelana phakathi kwe-section modulus kunye neemfuno zoyilo. Iimveliso ezenziwe ngobushushu zibonelela ngeendlela ezahlukeneyo ze-section, ezivumela iinjineli ukuba zikhethe iinkcukacha ezikufutshane neeparameter zoyilo ngaphandle kokunyusa ubunzima kakhulu. Xa kuthelekiswa nee-hot-rolled sheet piles, uyilo oludibeneyo lwee-cold-rolled sheet piles luvumela ukulungiswa okuphezulu kwe-engile yokujikeleza ye-25 degrees, okugqitha kakhulu uluhlu lokujikeleza lwe-7-10 degrees lweemveliso ezenziwe ngobushushu, ezibonelela ngeenzuzo ezibalulekileyo kwiimeko ezinzima ezifana nee-cofferdams ezigobileyo kunye nee-circular foundation pits.
Inqaku lesi-2 loKhetho oluPhambili: Ixesha lokuHanjiswa kunye neendleko zokuThutha
NgelixaIxabiso leeSheet PileKubalulekile ukuqwalaselwa, iindleko zizonke kufuneka zinikwe ingqwalasela engakumbi. Iimfumba zamaphepha ezenziwe ngobandayo ziveliswa ngamanani amakhulu aneeshedyuli zokuqengqeleka eziguquguqukayo, kunye nomjikelo wemveliso oqhelekileyo weeveki ezimbini kuphela, nto leyo enciphisa kakhulu ixesha lokulinda kwiprojekthi. Ngaphezu koko, ngenxa yokusasazwa ngokubanzi kwabathengisi beemfumba zamaphepha, abathengi banethuba elikhulu lokufumana ababoneleli abakufutshane, nto leyo enciphisa kakhulu iindleko zokuthutha umgama omde. "Ukufumaneka lula" kwezinto ngokwazo yinzuzo enkulu yeendleko.
Inkalo Yesithathu Yokukhetha: Ubuchule Bomthengisi
Ukukhetha okuthembekileyoababoneleli ngeenqwaba zephephakuthetha ukufumana kungekuphela nje iimveliso, kodwa nenkxaso yobugcisa kunye neziqinisekiso zokubonelela. Ababoneleli abaziingcali banokucebisa uhlobo lweenqwaba ezifanelekileyo kunye neenkcukacha ezisekelwe kwiimeko zejoloji yeprojekthi kunye nezicwangciso zokwakha, kwaye banikezele ngeenkonzo zokucubungula ezongeziweyo ezifana nokupeyinta kunye nokubhola. Ukusebenzisana nababoneleli abanamava eminyaka emininzi kushishino kuqinisekisa inkqubo egudileyo ukusuka kwingxoxo yokukhetha ukuya ekuhanjisweni kwindawo.
Ukulinganisela ukusebenza kobugcisa kunye neendleko zoqoqosho kubalulekile ekukhetheni ii-sheet piles. Ii-cold sheet piles, kunye nokuguquguquka kwazo kwenkqubo, iingenelo zeendleko, kunye nokuguquguquka kolwakhiwo, ziba lukhetho oluphambili kwinani elikhulayo leeprojekthi zobunjineli. Ukukhetha ababoneleli bee-sheet piles abanamava sisiqinisekiso esinamandla sokuguqula ezi nzuzo zibe yimpumelelo yeprojekthi.
