iibholi zokhuseleko zentsimbi

Ubunzulu obufakwe kwibhokisi buya kuhlangabezana neemfuno zoyilo, kwaye ubunzulu obunzulu buya kuhlangabezana nezi mfuno zilandelayo:
1. Xa i-casing ingcwatywa kumhlaba owomileyo okanye kumanzi aphantsi, ngenxa yomgangatho ongaphantsi ongenakuthintelwa, ubunzulu bokungcwaba kufuneka bube ngamaxesha angama-1.0-1.5 ububanzi obungaphandle be-casing, kodwa bungabi ngaphantsi kwe-1.0m; kuba umaleko ephantsi permeable ezifana nesanti kunye nentlenga, ubunzulu engcwatyiweyo iyafana ngasentla, kodwa Kucetyiswa ukuba indawo umhlaba ongenamanzi ukuba hayi ngaphantsi kwe-0.5m ngaphantsi komphetho ityhubhu ekhuselayo, kunye nedayamitha replacement kufuneka idlule ububanzi ityhubhu yokukhusela ngu 0.5-1.0m.
2. Kumanzi anzulu kunye nomhlaba othambileyo womlambo kunye nomaleko ongqindilili we-silt, umda ongezantsi wombhobho okhuselayo kufuneka ungene nzulu kumaleko angenakungena; ukuba akukho umaleko ungagxumekiyo, kufuneka ingene kwi-0.5-1.0m kwigrabile enkulu kunye nomaleko wengqalutye.
3. Kwimifula echatshazelwa kukuhlanjululwa, umda ophantsi wetyhubhu yokukhusela kufuneka ungene ngaphantsi kwe-1.0m ngaphantsi komgca we-scour jikelele. Kwimifula echatshazelwa kakhulu yi-scour yendawo, umda ongezantsi wombhobho wokukhusela kufuneka ungene ngaphantsi kwe-1.0m ngaphantsi komgca we-scour wendawo.
4. Kwiindawo zomhlaba ezikhenkcezisiweyo ngamaxesha, umda ophantsi wetyhubhu yokukhusela kufuneka ungene ngaphantsi kwe-0.5m kumaleko omhlaba angenamkhenkce ngaphantsi komgca wokukhenkceza; kwiindawo ze-permafrost, umda ophantsi we-tube yokukhusela kufuneka ungene kwi-permafrost layer engekho ngaphantsi kwe-0.5 m. 0.5m.
5. Kumhlaba owomileyo okanye xa ubunzulu bamanzi bungaphantsi kwe-3m kwaye akukho mhlaba obuthathaka ophantsi kwesiqithi, i-casing inokungcwatywa ngendlela evulekileyo, kunye nomhlaba wodongwe ozaliswe ngasezantsi kunye nokujikeleza kwe-casing kufuneka uhlanganiswe kwiingqimba.
6. Xa umzimba we-cylinder ungaphantsi kwe-3m, kwaye intlenga kunye nomhlaba othambileyo ophantsi kwesiqithi awunzima, indlela yokungcwaba evulekileyo ingasetyenziswa; Xa isando sitshona, indawo yendiza, ukuthambekela okuthe nkqo kunye nomgangatho wokudibanisa we-casing kufuneka ilawulwe ngokungqongqo.
7. Emanzini apho ubunzulu bamanzi bungaphezu kwe-3m, i-casing yokukhusela kufuneka incediswe yiplatifomu yokusebenza kunye nesakhelo sesikhokelo, kunye neendlela zokungcangcazela, ukubetha, ukubetha kwamanzi, njl njl.
8. Umphezulu ophezulu we-casing kufuneka ube ngu-2m ngaphezu komgangatho wamanzi wokwakha okanye umgangatho wamanzi aphantsi komhlaba, kunye ne-0.5m ngaphezu komhlaba wokwakha, kwaye ukuphakama kwawo kufuneka kuhlangabezane neemfuno zokuphakama kwendawo yodaka emngxunyeni.
9. Kwi-tube yokukhusela ebekwe endaweni, ukuphambuka okuvumelekileyo kwendawo ephezulu ngu-50mm, kwaye ukuphambuka okuvumelekileyo kokuthambekela ngu-1%.
