iibholi zokhuseleko zentsimbi

Ubunzulu obudityanisiweyo be-casing 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; kwimaleko esezantsi engenekayo njengesanti kunye nentlenga, ubunzulu obungcwatyiweyo buyafana nalapha ngasentla, kodwa Kuyacetyiswa ukuba kuthathelwe indawo ngomhlaba ongenamanzi ukuba ungabi ngaphantsi kwe-0.5m ngaphantsi komphetho wetyhubhu ekhuselayo, kunye nedayamitha yokutshintshwa kufuneka idlule. ububanzi betyhubhu yokukhusela nge-0.5-1.0m.
2. Kumanzi anzulu kunye nomhlaba othambileyo womlambo kunye nomaleko ongqindilili we-silt, umda ongezantsi wombhobho okhuselayo kufuneka ungene nzulu kumaleko angenamanzi; ukuba akukho maleko angagxumekiyo, kufuneka ingene kwi-0.5-1.0m kwigrabile enkulu kunye nomaleko wengqalutye.
3. Kwimifula echatshazelwa kukuhlanjululwa, umgca 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 wetyhubhu 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 maleko abuthathaka omhlaba emazantsi esiqithi, i-casing inokungcwatywa ngendlela evulekileyo, kwaye umhlaba wodongwe uzaliswe ezantsi kunye nokujikeleza. i-casing kufuneka ihlanganiswe kwiileya.
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%.
