Xa usakha iziseko zeemfumba kwiimeko zomqolomba wekarst, nanga amanye amanqaku aphambili ekufuneka uwaqwalasele:
UPhando lwe-Geotechnical: Yenza uphando olunzulu lwe-geotechnical phambi kolwakhiwo ukuqonda iimpawu zomqolomba wekarst, kubandakanywa nokusasazwa kwawo, ubungakanani, kunye neepateni zokuhamba kwamanzi ezinokwenzeka. Olu lwazi lubalulekile ekuyileni iziseko ezifanelekileyo zemfumba kunye nokuvavanya iingozi ezinokuthi zibe kho.
Ukukhethwa kohlobo lwemfumba: Khetha iintlobo zeemfumba ezilungele iimeko zekarst. Iinketho eziqhelekileyo ziquka i-drilled shaft piles, i-drilled steel pipes, okanye i-micro piles. Ukhetho kufuneka luthathele ingqalelo izinto ezinje ngomthamo wokuthwala umthwalo, ukuxhathisa ukubola, kunye nokulungelelaniswa kweempawu ezithile zekarst.
UYilo lwemfumba: Yila iziseko zemfumba ngokusekwe kuphando lwegeotechnical neemfuno zobunjineli. Qwalasela izitenxo kunye nokungaqiniseki okunxulumene neemeko zekarst. Qinisekisa ukuba uyilo lwengqumba luthathela ingqalelo umthamo wokuthwala, ulawulo lokuhlaliswa, kunye nokonakala okunokwenzeka.
Ubuchwephesha boFakelo lwemfumba: Khetha iindlela ezifanelekileyo zokufakela imfumba ngokusekwe kwiimeko zegeotechnical kunye neemfuno zoyilo lwemfumba. Ngokuxhomekeke kwiprojekthi ethile, ukhetho lunokubandakanya ukomba kunye nokugrumba, ukuqhuba imfumba, okanye ezinye iindlela ezikhethekileyo. Qinisekisa ukuba ubuchule obukhethiweyo bunciphisa ukuphazamiseka kumqolomba wekarst kwaye kugcine imfezeko yokwakheka kwamatye ajikelezileyo.
Ukukhuselwa kwemfumba: Khusela i-shafts yemfumba kwimiphumo eyingozi yeempawu zekarst ezifana nokuhamba kwamanzi okanye ukuchithwa. Amanyathelo afana nokusetyenziswa kwe-casing, grouting, okanye i-coatings ezikhuselayo zingasetyenziswa ukukhusela i-shafts yemfumba ekuwohlokeni okanye umonakalo.
Ukubeka iliso: Qalisa inkqubo yokuhlola ebanzi ngexesha lofakelo lweengqumba kunye nezigaba ezilandelayo zokwakha. Ukubeka iliso iiparameters ezifana nokuma kwemfumba, ukuhanjiswa komthwalo, kunye nokuhlaliswa kokuvavanya ukusebenza kweemfumba kunye nokufumanisa nayiphi na imiba enokubakho okanye ukuguqulwa ngexesha elifanelekileyo.
Amanyathelo okhuseleko: Ukuqinisekisa ukuba abasebenzi bokwakha bafumana uqeqesho olufanelekileyo kwaye babambelele kwimigaqo engqongqo yokhuseleko. Ukuphumeza amanyathelo okhuseleko ukunciphisa imingcipheko ehambelana nokusebenza kwiimeko zomqolomba wekarst, njengokubonelela ngezixhobo ezifanelekileyo zokukhusela umntu kunye nokuphumeza amaqonga omsebenzi akhuselekileyo.
Ulawulo loMngcipheko: Ukuphuhlisa isicwangciso sokulawula umngcipheko ojongene nemingeni ekhethekileyo yeemeko ze-karst cave. Esi sicwangciso kufuneka siquke imilinganiselo enokwenzeka, njengokuphatha ukungena kwamanzi okungalindelekanga, ukungazinzi komhlaba, okanye utshintsho kwiimeko zomhlaba. Vavanya rhoqo kwaye uhlaziye isicwangciso solawulo lomngcipheko njengoko iprojekthi iqhubela phambili.
Kubalulekile ukuba uqaphele ukuba iimeko zomqolomba wekarst zinokuba nzima kwaye zingalindelekanga. Ukubonisana neenjineli ezinamava kunye neengcali ezinobuchule kwi-karst geology kucetyiswa kakhulu ukuqinisekisa ulwakhiwo oluyimpumelelo lweziseko zeemfumba kwiindawo ezinjalo.
