Iimfumba zamaphepha zisetyenziswa kwizakhiwo zokugcina umhlaba apho kuya kusekwa umphezulu owahlukileyo.Ingqumba yamaphepha yenza ujongano oluthe nkqo.

Iimfumba zentsimbi yentsimbi zisetyenziselwa zombini iindonga zokugcina zethutyana kunye nesigxina.Ulwakhiwo lubandakanya amagumbi angaphantsi komhlaba, iindawo zokupakisha iimoto ezingaphantsi komhlaba kunye neebhulorho eziquka iibhulorho ezidityanisiweyo.

Izinto eziluncedo kwiMveliso:

I-1.Ngomthamo oqinileyo wokuthwala kunye nesakhiwo sokukhanya, udonga oluqhubekayo oluqulunqwe ngeemfumba zeshiti zensimbi lunamandla amakhulu kunye nokuqina.

I-2.Ukuqina kwamanzi okulungileyo, i-lock joint ye-steel sheet pile idibaniswe ngokusondeleyo, enokuthintela i-seepage ngokwemvelo.

I-3.Ulwakhiwo lulula, lunokulungelelanisa kwiimeko ezahlukeneyo ze-geological kunye nomgangatho womhlaba, kunokunciphisa umthamo wokumba womgodi wesiseko, umsebenzi uhlala kwindawo encinci.

I-4.Ukuqina okuhle, kuxhomekeke kumahluko kwindawo yokusetyenziswa, ubomi bunokuba yiminyaka engama-50.

5.Ukwakhiwa kuhambelana nokusingqongileyo, kwaye ubungakanani bomhlaba othathiweyo kunye nekhonkrithi esetyenziswayo iyancipha kakhulu, enokukhusela ngokufanelekileyo izibonelelo zomhlaba.

I-6.Ukusebenza ngokufanelekileyo, kukulungele kakhulu ukuphunyezwa ngokukhawuleza kolawulo lwezikhukhula, ukuwa, i-quicksand, inyikima kunye nezinye iintlekele kunye nokuthintela.

I-7.Izinto eziphathekayo zinokuphinda zisetyenziswe ngokuphindaphindiweyo, kwaye zingaphinda zisetyenziswe ngamaxesha angama-20-30 kwiiprojekthi zesikhashana.

8. Xa kuthelekiswa nezinye izakhiwo ze-monomer, udonga lulula kwaye lunokuguquguquka okukhulu kwi-deformation, efanelekileyo kuthintelo kunye nokunyangwa kweentlekele ze-geological ezahlukeneyo.
