Ulwakhiwo olungagungqiyo lubhekisa kwindlela yokwakha yokubeka okanye yokugalela imibhobho (imibhobho) kwimingxuma embiweyo phantsi komhlaba ecaleni kwendlela.umbhobho.Kukho indlela yokukhwela umbhobho, indlela yokukhwela ikhaka, indlela yokungcwaba engekho nzulu, indlela yokomba umkhombandlela, indlela yombhobho weramming, njl.

(1) Ukuvalwa kwemibhobho:

Izinto eziluncedo: ukuchaneka okuphezulu kokwakhiwa.Ukungalungi: ixabiso eliphezulu.

Ubungakanani besicelo: unikezelo lwamanzi kunye nemibhobho yokuhambisa amanzi, imibhobho edibeneyo: imibhobho esebenzayo.

Ububanzi bombhobho osebenzayo: 300-4000m.Ukuchaneka kolwakhiwo: ngaphantsi kwe±50mm.Umgama wokwakha: mde.

I-geology esebenzayo: iileya ezahlukeneyo zomhlaba.

(2) Indlela yekhaka

Izinto eziluncedo: isantya sokwakha ngokukhawuleza.Ukungalungi: ixabiso eliphezulu.

Ubungakanani besicelo: unikezelo lwamanzi kunye nemibhobho yokuhambisa amanzi, imibhobho edibeneyo.

Idayamitha yombhobho osebenzayo: ngaphezulu kwe-3000m.Ukuchaneka kolwakhiwo: ukungalawuleki.Umgama wokwakha: ubude.

I-geology esebenzayo: iileya ezahlukeneyo zomhlaba.

(3) Umbhobho wolwakhiwo olungekho nzulu (itonela) indlela

Izinto eziluncedo: ukusebenza ngamandla.Izinto ezingeloncedo: isantya esicothayo sokwakha kunye neendleko eziphezulu.

Ubungakanani besicelo: unikezelo lwamanzi kunye nemibhobho yokuhambisa amanzi, imibhobho edibeneyo.

Idayamitha yombhobho esebenzayo: ngaphezulu kwe-1000mm.Ukuchaneka kokwakhiwa: ngaphantsi okanye ukulingana ne-30mm.Umgama wokwakha: mde.

I-geology esebenzayo: iifom ezahlukeneyo.

(4) Ukwemba ngokuthe ngqo

Izinto eziluncedo: isantya sokwakha ngokukhawuleza.Ukungalungi: ukuchaneka kolawulo oluphantsi.

Ububanzi besicelo: iipayipi eziguquguqukayo.

Idayamitha yombhobho esebenzayo: 300mm-1000mm.Ukuchaneka kolwakhiwo: akukho ngaphezu kwe-0.5 amaxesha ombhobho ububanzi bangaphakathi.Umgama wokwakha: mfutshane.

Ijoloji esebenzayo: Ayisebenzi kwisanti, ingqalutye, kunye noluhlu oluqulatha amanzi.

(5) Indlela ye-tamping tube

Izinto eziluncedo: isantya sokwakha ngokukhawuleza kunye neendleko eziphantsi.Ukungalungi: ukuchaneka kolawulo oluphantsi.

Ububanzi besicelo: umbhobho wensimbi.

Umbhobho osebenzayo ububanzi: 200mm-1800mm.Ukuchaneka kolwakhiwo: ukungalawuleki.Umgama wokwakha: mfutshane.

I-geology esebenzayo: i-stratum ethwele amanzi ayifanelekanga, isanti kunye nelitye lelitye linzima.
