Ifomu lokukhipha i-bollard

Faka isigxobo ngokuya ngesizinda senqwaba, bese udweba i-arc eyindilinga nge-lime, bese ugaya umgodi noma umgibeli othambekele, bese ucindezela indawo ephakeme ye-cross inqwaba, bese ucindezela isikhundla senqwaba. Amaphoyinti wesikhungo ahlangatshezwayo, kanye ne-verticality kanye nesikhundla esivundlile se-casing kufanele kulungiswe ngesando somugqa. Izinga lokuthambekela akufanele libe likhulu kune-1%, futhi ukuphambuka akufanele kube kukhulu kune-50ram. Lapho engcwaba amacala, izindawo ezizungezile kufanele zibuyiselwe ubumba esezingeni eliphakeme, futhi zihlanganiswe ngokulinganayo ezingxenyeni ezithile. Ububanzi obungaphakathi be-casing kufanele bubuyiselwe emuva. Kufanele kube ngu-20- 40cm makhulu kune ububanzi be-pile, kanye nokujula okuvinjelwe okujwayelekile ngu-200-400cm. Lapho ungcwaba amacala, kuphakama ama-30cm kunokwemvelo, futhi kuvulwa indawo ethambile phezulu, ebheke emgodini odaka. Ezimweni ezikhethekile, ukujula kwe-casing kungandiswa, futhi ubukhulu bodaka bungandiswa (udaka lungathululelwa ebumbeni), futhi umthelela ungahamba kancane. Ngokungenisa i-Level Yezinga Lamanzi eCasing. Uma umphetho weshubhu elivikelayo uvezwa ngamanzi, okuzungezile kungagcwala ubumba ukuze kuqinise ishubhu elivikelayo. Ukuncishiswa okukhulu nokufuduka kufanele kuphinde kusetshenziswe futhi kushunyezwe kabusha ukuvikela i-casing; Uma udonga lomgodi ovuthayo olushayiwe, lungavuselelwa lube yi-Clay noma i-Green Potassium (i-pot powder) ukuze yenze ukwanda kwengxenye kadaka; Ngemuva kokungcwatshwa kwecala, kufanele kusetshenziswe umugqa wesando nombusi wezinkuni, ukukala ibanga ukusuka emaphethelweni we-casing enkabeni yesikhundla (noma ekuqondisweni okuqondile nokuvundlile kwendlela), futhi wenze amarekhodi okuqala okwakha. Ukuphambuka, ukuphambuka akufanele kube kukhulu kune-5M. Futhi izinhlayiya zonogada zingcwatshwa emlonyeni walowo onogada (ukungcwatshwa endaweni yesiphambano kanye namamaki amane kudonswa), ukuze ophasi abaphethe kanye nomhloli wekhwalithi bangasebenzisa indlela yesiphambano ukuthola isikhundla senqwaba.
