amabhodi okuphepha ensimbi

Ukujula okushumekiwe kwekesi kuzohlangabezana nezidingo zedizayini, futhi ukujula okushumekiwe kuzohlangabezana nezidingo ezilandelayo:
1. Lapho i-casing ingcwatshwa emhlabathini owomile noma emanzini angajulile, ungqimba olungaphansi olungenakunyakaziswa, ukujula kokungcwaba kufanele kube izikhathi ezingu-1.0-1.5 ububanzi obungaphandle be-casing, kodwa kungabi ngaphansi kuka-1.0m; ongqimbeni olungaphansi oluvunyelekayo njengesihlabathi nodaka, ukujula okungcwatshwe kuyafana nangaphezulu, kodwa kuyatuseka ukuthi esikhundleni senhlabathi engenakunyakaziswa ibe ngaphansi kuka-0.5m ngaphansi konqenqema lweshubhu elivikelayo, futhi ububanzi bokubuyisela kufanele budlule ububanzi beshubhu lokuvikela ngo-0.5-1.0m.
2. Emanzini ajulile nasenhlabathini ethambile yomfula kanye nongqimba oluqinile lwe-silt, unqenqema olungaphansi lweshubhu lokuvikela kufanele lungene lujule kungqimba olungangeneli; uma lungekho ungqimba olungangeneki, kufanele lungene ku-0.5-1.0m ongqimbeni olukhulu lwamatshe amatshe.
3. Ezingxenyeni zomfula ezithintwe ukukhuhla, unqenqema olungezansi lweshubhu lokuvikela kufanele lungene ngaphansi kuka-1.0m ngaphansi komugqa ojwayelekile wokukhuhla. Ezingxenyeni zemifula ezithinteke kakhulu ngenxa ye-scour yendawo, unqenqema olungezansi lweshubhu lokuvikela kufanele lungene ngaphansi kuka-1.0m ngaphansi komugqa wendawo.
4. Ezindaweni zenhlabathi eqandisiwe ngezikhathi ezithile zonyaka, unqenqema olungaphansi lweshubhu lokuvikela kufanele lungene ngaphansi kuka-0.5m ongqimbeni lwenhlabathi olungaqandisiwe ngaphansi komugqa oqandayo; ezindaweni ze-permafrost, unqenqema oluphansi lweshubhu lokuvikela kufanele lungene kungqimba lwe-permafrost olungekho ngaphansi kuka-0.5 m. 0.5m.
5. Ezweni elomile noma lapho ukujula kwamanzi kungaphansi kwama-3m futhi kungekho ungqimba lomhlabathi obuthakathaka ngaphansi kwesiqhingi, i-casing ingagqitshwa ngendlela yokusika okuvulekile, futhi inhlabathi yobumba igcwaliswe phansi kanye nendawo ezungezile. i-casing kufanele ihlanganiswe ngezingqimba.
6. Uma umzimba we-cylinder ungaphansi kwama-3m, futhi inhlabathi enodaka nethambile ngaphansi kwesiqhingi ingeqinile, indlela yokungcwaba evulekile ingasetshenziswa; Lapho isando sicwila, ukuma kwendiza, ukuthambekela okuqondile kanye nekhwalithi yokuxhumana ye-casing kufanele ilawulwe ngokuqinile.
7. Emanzini lapho ukujula kwamanzi kungaphezu kwama-3m, i-casing evikelayo kufanele isize ngeplatifomu yokusebenza kanye nohlaka lomhlahlandlela, futhi izindlela zokudlidliza, ukushaya ngesando, i-jetting yamanzi, njll. kufanele zisetshenziselwe ukucwila.
8. Ingaphezulu le-casing kufanele libe ngama-2m ngaphezu kwezinga lamanzi okwakhiwa noma izinga lamanzi angaphansi komhlaba, futhi libe ngu-0.5m ngaphezu kwendawo yokwakha, futhi ukuphakama kwayo kusafanele kuhlangabezane nezidingo zokuphakama kwendawo yodaka emgodini.
9. Ukuze kubekwe ithubhu yokuvikela endaweni, ukuphambuka okuvumelekile kwendawo ephezulu kungu-50mm, futhi ukuphambuka okuvumelekile kokuthambekela kungu-1%.
