Xa ubeka ibhodi yokuthintela amanzi kwitonela, kuyafuneka ukuba ulandele ngokuthe ngqo ezi nkqubo zilandelayo:
1. Iindawo ezigqamileyo njengentsimbi yomnatha kufuneka zisikwe kuqala zize zigudiswe ngothuthu lodaka.
2. Xa kukho imibhobho ephumayo, yinqumle kwaye uyigudise ngodaka.
3. Xa kukho inxalenye ephumayo yentonga ye-anchor ye-tunnel yepleyiti engenamanzi, umphezulu wentloko ye-screw igcinwe i-5mm kwaye inqunyulwe, kwaye iphathwa nge-cap yeplastiki.
4. Yenza umphezulu ube bushelelezi kwaye ube mpuluswa ngokutshiza ikhonkrithi, kwaye umlinganiselo wokungalingani akufanele udlule ± 5cm.
5. Kwi-concrete surface, i-350g / m2 geotextile kufuneka ifakwe kwi-liner kuqala, kwaye xa kukho ibhodi yokuhambisa amanzi, kufuneka ifakwe ngexesha elifanayo, kwaye emva koko izikhonkwane ze-samente kufuneka zibethelelwe nge-nail gun ukuze kufakwe i-anchoring. , kwaye ubude bezikhonkwane zesamente akufanele kube ngaphantsi kwama-50mm. Umyinge we-vault ngamanqaku angama-3-4 / m2, kwaye udonga olusecaleni luyi-2-3 amaphuzu / m2.
6. Ukuze uthintele i-sement slurry ukuba ingangeni kwi-geotextile, kuqala ubeke i-geotextile uze ubeke ibhodi ye-tunnel engenamanzi.
7. Xa ubeka ibhodi engangeni manzi, sebenzisa i-welder ekhethekileyo ye-manual ukutshisa-ukunyibilika kwi-liner, kunye nokuqina kwe-bonding kunye ne-peeling yezo zibini akufanele zibe ngaphantsi kwamandla angaphantsi kwebhodi engenamanzi.
8. Isixhobo esikhethekileyo se-welding sisetyenziselwa i-hot-melt bonding phakathi kweebhodi ezingenamanzi, inxalenye edibeneyo ayiyi kuba ngaphantsi kwe-10cm, kwaye ukuqina kwe-peeling yokudibanisa akuyi kuba ngaphantsi kwe-80% yamandla obunzima bomzimba womzali.
9. Umgama phakathi kwebhondi ejikelezayo yebhodi yokuthintela amanzi kwitonela kunye ne-lining joint ayiyi kuba ngaphantsi kwe-1.0m. Ngaphambi kokuba kubekwe umgca wokukhusela amanzi, ibhodi yokukhusela amanzi ayiyi kuqiniswa, kwaye ubuso bebhodi buya kufakwa ngokusondeleyo kumphezulu we-shotcrete kwaye ayiyi kuhluthwa.
