Idizayinelwe futhi yathuthukiswa inkampani yethu, i-hydraulic tunnel lining trolley iwuhlelo olufanele lolwelwesi lukajantshi wesitimela nothelawayeka. Ishayelwa amamotho kagesi, iyakwazi ukuzinyakazisa futhi izihambela yodwa, kusetshenziswe isilinda esisebenza ngehydraulic kanye nesikulufa sikajack ukuze simise futhi sibuyise i-formwork. I-trolley inezinzuzo eziningi ekusebenzeni, njengezindleko eziphansi, isakhiwo esithembekile, ukusebenza okulula, isivinini somugqa osheshayo kanye nomhubhe omuhle.
I-trolley ngokuvamile iklanywe njengohlobo lwe-arch yensimbi, kusetshenziswa ithempulethi yensimbi ehlanganisiwe evamile, ngaphandle kokuhamba ngokuzenzekelayo, kusetshenziswa amandla angaphandle ukudonsa, futhi ithempulethi ye-detachment yonke iqhutshwa ngesandla, esebenza kanzima. Lolu hlobo lwe-trolley yomugqa ngokuvamile lusetshenziselwa ukwakhiwa komhubhe omfushane, ikakhulukazi ekwakhiweni komugqa kakhonkolo womhubhe ngendiza eyinkimbinkimbi kanye nejometri yesikhala, ukuguqulwa kwenqubo njalo, kanye nezidingo eziqinile zenqubo. Izinzuzo zayo zisobala kakhulu. Umugqa wesibili oqiniswe ukhonkolo wamukela uhlaka olulula lwe-arch, oluxazulula lezi zinkinga kahle, futhi ngesikhathi esifanayo, izindleko zobunjiniyela ziphansi. Iningi lama-trolleys alula lisebenzisa ukuthulula ukhonkolo wokwenziwa, futhi i-trolley ye-lining elula igcwele amaloli epompo ahambisa ukhonkolo, ngakho-ke ukuqina kwe-trolley kufanele kuqiniswe ikakhulukazi. Amanye ama-trolleys alula asebenzisa i-inteel Steel Formwork, kodwa asasebenzisa ama-threaded rods futhi awanyakazi ngokuzenzakalelayo. Lolu hlobo lwe-trolley luvame ukugcwaliswa ngamaloli epompo yokulethwa kukakhonkolo. Ama-trolleys alula ngokuvamile asebenzisa i-formwork yensimbi ehlanganisiwe. I-formwork yensimbi ehlanganisiwe ngokuvamile yenziwa ngamapuleti amancane.
Ukuqina kwe-formwork yensimbi kufanele kucatshangelwe enqubweni yokuklama, ngakho-ke isikhala phakathi kwama-arches ensimbi akufanele sibe sikhulu kakhulu. Uma ubude besakhiwo sensimbi buyi-1.5m, isilinganiso esimaphakathi phakathi kwamakhothamo ensimbi akumele sibe sikhulu kuno-0.75m, futhi ijoyinti le-longitudinal le-formwork yensimbi kufanele isethwe phakathi kokuphusha nokucindezela ukuze kube lula ukufakwa kwezibophelelo ze-formwork. kanye nezingwegwe ze-formwork. Uma iphampu isetshenziselwa ukumnika, isivinini sokumnika akufanele sisheshe kakhulu, ngaphandle kwalokho kuzodala ukuwohloka kokwakheka kwensimbi eyinhlanganisela, ikakhulukazi lapho ukushuba kolwelwesi kungaphezu kuka-500mm, isivinini sokumnika kufanele sehliswe. Qaphela lapho uvala futhi uthela. Naka ukuthululwa kokhonkolo ngaso sonke isikhathi ukuvimbela ukuthulula ukhonkolo ngemva kokugcwalisa, ngaphandle kwalokho kuzobangela ukuqhuma kwesikhunta noma ukuguqulwa kwetrolley.
