Umsebenzi we-welding chambered ameva emzimbeni wepayipi ukuvimbela ukungena kwesihlabathi noma ezinye izinto ekuvimbeleni imbobo ye-grouting.

Ipayipi lezimbali lensimbi liyindlela yenqubo ku-tunneling kanye nenqubo yokwakha yephrojekthi yokwesekwa kwemithambeka. Isetshenziselwa kakhulu indawo yokuphuka ebuthakathaka, ingxenye engcwatshwe kancane, ingxenye echemile yokungena emhumeni, ingxenye yesihlabathi, ingxenye yesihlabathi, nengxenye yetshe phakathi nesikhathi sokuzinzisa. Ukuvikela okukhokhelwa kusengaphambili kwezindawo ezifana nezindawo zokuphuka kwamaphutha.

Ipayipi lembali yensimbi iyindlela ephumelela kakhulu yokwakha eyisizayo ngaphandle kokumbiwa kwesiphithiphithi sobuso obusebenzayo. Ekwakhiweni kwamadwala abuthakathaka futhi aphukile, imigudu emincane ehamba phambili ingaqinisa ukwakheka kwamadwala okuxekethile. Ngemuva kwe-grouting, ukuqina kwamadwala azungezile akhululekile futhi abuthakathaka kuyathuthukiswa, okuzuzisa ukwakhiwa kwedwala elizungezile ngemva kokuphothulwa kokumba futhi ngesikhathi sokusekelwa kokuqala Ngeke kube nesiphithiphithi, futhi idwala elizungezile ngeke lilahlekelwe ukuzinza. noma imbala.
