Lapho wakha izisekelo zenqwaba ezimweni zomhume we-karst, nanka amaphuzu abalulekile okufanele uwacabangele:
Uphenyo Lwe-Geotechnical: Yenza uphenyo olunzulu lwe-geotechnical ngaphambi kokwakhiwa ukuze uqonde izici zomhume we-karst, okuhlanganisa ukusatshalaliswa kwawo, usayizi, kanye namaphethini okugeleza kwamanzi okungenzeka. Lolu lwazi lubalulekile ekuklameni izisekelo ezifanele zenqwaba kanye nokuhlola ubungozi obungaba khona.
Ukukhetha Uhlobo Lwenqwaba: Khetha izinhlobo zenqwaba ezifanele izimo ze-karst. Izinketho ezijwayelekile zifaka izinqwaba zamapayipi ensimbi, izinqwaba zamapayipi ensimbi, noma izinqwaba ezincane. Okukhethiwe kufanele kucabangele izici ezifana nomthamo wokuthwala umthwalo, ukumelana nokugqwala, nokuvumelana nezimo ezithile ze-karst.
I-Pile Design: Dizayina izisekelo zenqwaba ngokusekelwe ophenyweni lwe-geotechnical kanye nezidingo zobunjiniyela. Cabangela ukungahambi kahle nokungaqiniseki okuhlobene nezimo ze-karst. Qinisekisa ukuthi idizayini yenqwaba ibheka umthamo wokuthwala, isilawuli sokuhlala, kanye nokukhubazeka okungenzeka.
Izindlela Zokufaka Inqwaba: Khetha amasu afanelekile okufaka inqwaba asekelwe ezimeni ze-geotechnical kanye nezidingo zokuklama inqwaba. Ngokuya ngephrojekthi ethile, izinketho zingabandakanya ukubhoboza nokugxusha, ukushayela inqwaba, noma ezinye izindlela ezikhethekile. Qinisekisa ukuthi indlela ekhethiwe inciphisa ukuphazamiseka emgedeni we-karst futhi igcina ubuqotho bokwakheka kwamadwala azungezile.
Ukuvikelwa Kwenqwaba: Vikela imigodi yenqwaba emiphumeleni egugulekayo yezici ze-karst njengokugeleza kwamanzi noma ukuncibilika. Izinyathelo ezifana nokusetshenziswa kwe-casing, grouting, noma okokuvikela kungaqashwa ukuze kuvikelwe ama-shaft enqwaba ekuwohlokeni noma emonakalweni.
Ukuqapha: Ukusebenzisa uhlelo lokuqapha oluphelele ngesikhathi sokufakwa kwenqwaba kanye nezigaba zokwakhiwa ezilandelayo. Gada amapharamitha afana nokuma kwenqwaba, ukudluliswa komthwalo, kanye nokuxazululwa ukuze uhlole ukusebenza kwezinqwaba futhi uthole noma yiziphi izinkinga ezingaba khona noma ukonakala ngesikhathi.
Izinyathelo Zokuphepha: Qinisekisa ukuthi abasebenzi bezokwakha bathola ukuqeqeshwa okufanele futhi banamathele ezimisweni zokuphepha eziqinile. Sebenzisa izindlela zokuphepha ukuze unciphise ubungozi obuhlobene nokusebenza ngaphansi kwezimo zomhume we-karst, njengokuhlinzeka ngezinto ezanele zokuzivikela kanye nokusebenzisa izinkundla zokusebenza ezivikelekile.
Ukulawulwa Kwengozi: Yenza uhlelo lokulawula ubungozi olubhekana nezinselelo eziyingqayizivele zezimo ze-karst cave. Lolu hlelo kufanele lubandakanye izinyathelo eziphuthumayo, njengokuphatha ukungena kwamanzi okungalindelekile, ukungazinzi komhlabathi, noma izinguquko ezimweni zasemhlabeni. Hlala uhlola futhi ubuyekeze uhlelo lokulawulwa kwezinhlekelele njengoba iphrojekthi iqhubeka.
Kubalulekile ukuqaphela ukuthi izimo zomhume we-karst zingaba yinkimbinkimbi futhi zingalindeleki. Ukubonisana nonjiniyela be-geotechnical abanolwazi nochwepheshe abanolwazi lwe-karst geology kunconywa kakhulu ukuze kuqinisekiswe ukwakhiwa ngempumelelo kwezisekelo zenqwaba ezindaweni ezinjalo.
