ama-bollos e-steel
Ukujula okushumekiwe kwecala kuzohlangabezana nezidingo zokuklama, kanye nokujula okushumekiwe kuzohlangabezana nalezi zidingo ezilandelayo:
1. Lapho i-casing ingcwatshwa emhlabathini owomile noma emanzini angajulile, ngesendlalelo esingenamkhawulo, ukujula komngcwabo kufanele kube ngu-1.0-1,5 izikhathi eziyi-1.0-1,5 the auter the casing, kodwa hhayi ngaphansi kwe-1,0m; Ngesendlalelo esingezansi esingezansi njengesihlabathi kanye nesilika, ukunzwa okungcwatshwe kuyafana nangaphezulu, kepha kungakuhle ukufaka esikhundleni senhlabathi engabi nalutho hhayi ngaphansi konqenqemeni lweshubhu elivikelayo, futhi ububanzi bokufakwa esikhundleni kufanele budlule ububanzi be-Tube elivikelayo nge-0.5-1.0m.
2. Emanzini ajulile nangomfula othambile othambile kanye nongqimba olucwebezelayo, umphetho ophansi weshubhu elivikelayo kufanele ujule ungene kungqimba olungenakufinyeleleka; Uma kungekho ungqimba olungafinyeleleki, kufanele ufake i-0.5-1,0m ku-gravel enkulu ne-pebble urler.
I-3. Okokuqala kwathinteka ngokuhlanza, umphetho ophansi weshubhu elivikelayo kufanele ufake ngaphansi kwe-1.0m ngezansi komugqa ojwayelekile. Ukuze ama-Riverbeds athinteka kakhulu esihlahleni sendawo, umphetho ophansi weshubhu elivikelayo kufanele ufake ngaphansi kwe-1.0m ngezansi komugqa wendawo.
4 Ezindaweni ze-permafrost, onqenqemeni oluphansi lweshubhu elivikelayo kufanele ungene engxenyeni ye-permafrost ayikho ngaphansi kuka-0,5 m. 0.5m.
5. Emhlabeni owomile noma lapho ukujula kwamanzi kungaphansi kwama-3m futhi akukho ungqimba lomhlabathi olubuthakathaka phansi esiqhingini, lapho i-casing ingangcwatshwa ngendlela enqunywe khona, futhi inhlabathi yobumba igcwele phansi kanye nokubanjwa kwe-casing kumele kuhlanganiswe ezingxenyeni.
6. Lapho umzimba we-cylinder ungaphansi kwama-3m, futhi inhlabathi ethambile nomhlabathi othambile ezansi kwesiqhingi ayiminyene, indlela evulekile yokungcwatshwa ingasetshenziswa; Lapho isando sicwila, isikhundla sendiza, ukuthambekela okuqondile kanye nekhwalithi yokuxhumana yecala kufanele kulawulwe ngokuqinile.
7. Emanzini lapho ukujula kwamanzi kukhulu kune-3m, ukufundwa okuvikelayo kufanele kusizwe yipulatifomu yokusebenza kanye nezindlela zokudlidliza, nezindlela zokudlidliza, i-hammeng, Jettting, njll. Kufanele isetshenziswe ukucwila.
8
9. Ishubhu elivikelayo elisethwe endaweni, ukuphambuka okuvumelekile kwendawo ephezulu kungu-50mm, futhi ukuphambuka okuvumelekile kokuthambekela kungu-1%.
