Umahluko phakathi kwendlela yokuthintela i-hydraulic engafakwanga nzulu kunye nendlela yokuthintela i-hydraulic engafakwanga nzulu – (2)

Iyaqhubeka ukusuka kwinqaku elidlulileyo

3. Kulula ukugcinwa nokusetyenziswa: shallow billed vs deep billed

Kungcwatywe nzuluindlela yokumisa umqobo:

• Iingenelo: Izixhobo ezingaphantsi komhlaba zilungele ukulungiswa nokugcinwa, ingakumbi ukuhlolwa nokulungiswa kwezinto ezifana neenkqubo ze-hydraulic kunye neenkqubo zolawulo. Ekubeni izixhobo zifakelwe ngaphantsi komhlaba, ukumba komhlaba omkhulu akusoloko kuyimfuneko.

• Iingxaki: Izixhobo zinokuba sesichengeni sokuchaphazeleka kokusingqongileyo (njengokuqokelelwa kwamanzi kunye nenkunkuma) ngexesha lokusetyenziswa, kwaye kufuneka kuqwalaselwe ngokukodwa ukhuseleko ngexesha lokugcinwa kwazo.

Indlela efihliweyo nzulu:

• Iingenelo: Ngenxa yobunzulu bayo obukhulu, izixhobo ezifakwe nzulu azichaphazeleki kakhulu yimeko-bume yomphezulu kwaye zinokugcina ukusebenza okuzinzileyo xa zisetyenziswa ixesha elide.

• Iingxaki: Ukugcinwa kwezixhobo ezingcwatywe nzulu kunzima ngakumbi. Ukuba inkqubo ye-hydraulic, inkqubo yokulawula kunye nezinye izinto kufuneka zilungiswe okanye zitshintshwe, inxalenye engcwatywe yezixhobo inokufuna ukugrunjwa kwakhona, nto leyo eyandisa ixesha kunye neendleko.

4. Iindawo ezisebenzayo: ezingaphantsi komhlaba zingcwatywe kakhulu vs ezingcwatywe kakhulu

Indlela engavalwanga kakuhle:

• Iindawo ezifanelekileyo: Zifanelekile kwiindawo ezineemfuno zomjikelo omfutshane wokufakelwa, indawo encinci engaphantsi komhlaba, kunye neemeko zomhlaba, njengeendlela zasezidolophini, iingcango zokungena kwiindawo zorhwebo, kunye nezinye iindawo apho ukwakhiwa okukhulu kungavumelekanga.Iindlela ezivaliweyo ezinganzulu kangakozifanelekile kwiindawo ezineemfuno eziphezulu zokuhamba.

Ngcwatywe nzuluimiqobo:

• Iindawo ezifanelekileyo: Zifanelekile kwiindawo ezineemfuno zokhuseleko eziphezulu kakhulu kwaye zinokumelana nobuninzi bokwakha obukhulu, njengee-arhente zikarhulumente, iziseko zomkhosi, izakhiwo zokhuseleko eziphezulu, njl. Izixhobo ezigqunywe nzulu zinokugcina uzinzo ixesha elide kwaye azichaphazeleki lula kukuphazamiseka kwangaphandle.

5. Uthelekiso lweendleko: I-Shallow buried vs. deep buried

Kungcwatywe nzuluimiqobo:

• Ixabiso eliphantsi: Ngenxa yobunzulu bokufakelwa obunganzulu kangako, ulwakhiwo lulula kakhulu, kwaye iindleko zobunjineli bokwakha ezifunekayo ziphantsi, nto leyo efanelekileyo kwiiprojekthi ezinebhajethi yeendleko ezilinganiselweyo.

Ngcwatywe nzuluimiqobo:

Ixabiso eliphezulu: Ukufakelwa kweemodeli ezingcwatywe nzulu kufuna iziseko zophuhliso ezingaphezulu kunye nexesha elide lokwakha, ngoko ke iindleko zayo zizonke ziphezulu, nto leyo efanelekileyo kwiiprojekthi ezinebhajethi eyaneleyo.

Iingcebiso zokukhetha:

• Uhlobo olungaphantsi komhlaba olungaphantsi komhlaba lufanelekile kwiindawo ezifuna ukufakelwa ngokukhawuleza, ixesha elifutshane lokwakha, kunye nesiseko esilula phantsi komhlaba. Lufanelekile kwezinye iindawo zolawulo lwezithuthi zemihla ngemihla kunye nokhuseleko.
• Uhlobo olugqunywe nzulu lufanelekile kwiindawo ezineemfuno zokhuseleko eziphezulu kakhulu, ingakumbi kwiindawo apho izixhobo kufuneka zisebenze ngokuzinzileyo ixesha elide kwaye zimelane nempembelelo enamandla kakhulu, lunokubonelela ngokhuseleko oluthembekileyo ngakumbi.
