Lapho ubeka ibhodi lokuvimbela amanzi lomhubhe, kuyadingeka ukuthi ulandele ngokuqinile izinqubo ezilandelayo:
1. Izingxenye eziphumela ngaphandle njengensimbi yensimbi kufanele zisikwe kuqala bese zibushelelezi ngomlotha wodaka.
2. Uma kunamapayipi aphumile, wanqamule bese uwashelela ngodaka.
3. Uma kunengxenye ephumela ngaphandle yenduku yehange yepuleti elingangeni amanzi emhubheni, ingaphezulu lekhanda lesikulufu ligodliwe ngo-5mm bese linqanyulwa, bese liphathwa ngekepisi lepulasitiki.
4. Yenza ubuso bushelelezi futhi bushelelezi ngokufafaza ukhonkolo, futhi inani lokungalingani akufanele lidlule ± 5cm.
5. Phezu kukakhonkolo, i-geotextile engu-350g/m2 kufanele inanyathiselwe kuqala nge-liner, futhi uma kunebhodi lokudonsa amanzi, kufanele linamathiselwe kanyekanye, bese izipikili zikasimende zibethelwe ngesibhamu sezinzipho ukuze kumiswe ihange. , futhi ubude bezinzipho zikasimende akufanele bube ngaphansi kuka-50mm. I-vault evamile ingamaphuzu angu-3-4/m2, futhi udonga oluseceleni lungamaphuzu angu-2-3/m2.
6. Ukuze uvimbele udaka lukasimende ukuthi lungangeni ku-geotextile, qala ngokubeka i-geotextile bese ubeka ibhodi lomhubhe elingangeni manzi.
7. Uma ubeka ibhodi elingangeni manzi, sebenzisa i-welder ekhethekile ye-manual ukuze ushise-uncibilike ku-liner, futhi amandla okubopha kanye nokuxebula kokubili akufanele kube ngaphansi kwamandla aqinile ebhodi elingangeni manzi.
8. Umshini wokushisela okhethekile usetshenziselwa ukuhlangana okuncibilika okushisayo phakathi kwamabhodi angangeni manzi, ingxenye ehlangene akufanele ibe ngaphansi kuka-10cm, futhi amandla okuxebuka okubophayo angabi ngaphansi kuka-80% wamandla aqinile omzimba womzali.
9. Ibanga eliphakathi kwebhondi eyindilinga yebhodi lokuvikela amanzi emhubheni kanye nejoyinti yomugqa akufanele libe ngaphansi kuka-1.0m. Ngaphambi kokuba kubekwe ungqimba wokuvimbela amanzi, ibhodi lokuvimbela amanzi akufanele liqiniswe, futhi ubuso bebhodi buzoxhunyaniswa eduze nobuso be-shotcrete futhi akufanele bukhishwe.
