Uma wakha izisekelo zezinqwaba ezimweni zomhume waseKarst, nanka amaphuzu abalulekile okufanele uwacabangele:
Uphenyo Lobuchwepheshe Bendawo: Yenza uphenyo olunzulu lwendawo ngaphambi kokwakhiwa ukuze uqonde izici zomhume wase-karst, okuhlanganisa ukusabalala kwawo, ubukhulu, kanye namaphethini okugeleza kwamanzi okungenzeka. Lolu lwazi lubalulekile ekwakheni izisekelo ezifanele zezinqwaba kanye nokuhlola izingozi ezingaba khona.
Ukukhetha Uhlobo Lwezinqwaba: Khetha izinhlobo zezinqwaba ezifanele izimo ze-karst. Izinketho ezivamile zifaka phakathi izinqwaba zomgodi ezibholiwe, izinqwaba zamapayipi ensimbi ezibholiwe, noma izinqwaba ezincane. Ukukhetha kufanele kucabangele izici ezifana nomthamo wokuthwala umthwalo, ukumelana nokugqwala, kanye nokuzivumelanisa nezimo ezithile ze-karst.
Umklamo Wezinqwaba: Dala izisekelo zezinqwaba ngokusekelwe ezidingweni zophenyo lwe-geotechnical kanye nobunjiniyela. Cabanga ngokungahambi kahle kanye nokungaqiniseki okuhlobene nezimo ze-karst. Qinisekisa ukuthi umklamo wezinqwaba ucabangela amandla okuthwala, ukulawula ukuhlala, kanye nokuguquguquka okungenzeka.
Amasu Okufaka Izinqwaba: Khetha amasu okufaka izinqwaba afanele ngokusekelwe ezimweni zobuchwepheshe bezwe kanye nezidingo zokuklama izinqwaba. Kuye ngephrojekthi ethile, izinketho zingafaka phakathi ukubhoboza nokufaka i-grouting, ukushayela izinqwaba, noma ezinye izindlela ezikhethekile. Qinisekisa ukuthi inqubo ekhethiwe inciphisa ukuphazamiseka emhumeni we-karst futhi igcina ubuqotho bezakhiwo zamadwala ezizungezile.
Ukuvikelwa Kwezinqwaba: Vikela imigoqo yezinqwaba emiphumeleni yokuguguleka kwezici ze-karst njengokugeleza kwamanzi noma ukuncibilika. Izindlela ezifana nokusetshenziswa kwe-casing, grouting, noma izembozo zokuvikela zingasetshenziswa ukuvikela imigoqo yezinqwaba ekuwohlokeni noma ekulimaleni.
Ukuqapha: Sebenzisa uhlelo lokuqapha oluphelele ngesikhathi sokufakwa kwenqwaba kanye nezigaba zokwakha ezilandelayo. Qapha imingcele efana nokuma kwenqwaba, ukudluliselwa komthwalo, kanye nokulungiswa ukuze uhlole ukusebenza kwenqwaba futhi uthole noma yiziphi izinkinga ezingaba khona noma ukuguquguquka ngesikhathi esifanele.
Izinyathelo Zokuphepha: Qinisekisa ukuthi abasebenzi bokwakha bathola ukuqeqeshwa okufanele futhi balandela izinqubo zokuphepha eziqinile. Sebenzisa izinyathelo zokuphepha ukunciphisa izingozi ezihlobene nokusebenza ezimweni zomhume wase-karst, njengokuhlinzeka ngemishini yokuzivikela eyanele kanye nokusebenzisa amapulatifomu okusebenza aphephile.
Ukuphathwa Kwengozi: Yakha uhlelo lokuphathwa kwengozi olubhekana nezinselele ezihlukile zezimo zomhume wase-karst. Lolu hlelo kufanele luhlanganise izinyathelo eziphuthumayo, njengokusingatha ukungena kwamanzi okungalindelekile, ukungazinzi komhlabathi, noma izinguquko ezimweni zomhlabathi. Hlola njalo futhi ubuyekeze uhlelo lokuphathwa kwengozi njengoba iphrojekthi iqhubeka.
Kubalulekile ukuqaphela ukuthi izimo zomhume wase-karst zingaba nzima futhi zingabikezeleki. Ukubonisana nonjiniyela be-geotechnical abanolwazi kanye nochwepheshe abanolwazi lwe-karst geology kunconywa kakhulu ukuqinisekisa ukwakhiwa okuphumelelayo kwezisekelo zezinqwaba ezindaweni ezinjalo.
