Chopangidwa ndi kupangidwa ndi kampani yathu, trolley ya hydraulic tunnel lining ndi njira yabwino kwambiri yopangira formwork ya framework ya njanji ndi misewu ikuluikulu. Yoyendetsedwa ndi ma mota amagetsi, imatha kuyenda yokha, ndipo hydraulic silinda ndi screw jack zimagwiritsidwa ntchito kuyimitsa ndikuchotsa formwork. Trolley ili ndi zabwino zambiri zogwirira ntchito, monga mtengo wotsika, kapangidwe kodalirika, kugwiritsa ntchito kosavuta, liwiro la framework komanso malo abwino a tunnel.
Trolley nthawi zambiri imapangidwa ngati mtundu wa arch yachitsulo, pogwiritsa ntchito template yachitsulo chophatikizana, popanda kuyenda yokha, pogwiritsa ntchito mphamvu zakunja kukoka, ndipo template yochotsera yonse imagwiritsidwa ntchito pamanja, zomwe zimafuna ntchito yambiri. Mtundu uwu wa trolley nthawi zambiri umagwiritsidwa ntchito popanga ngalande zazifupi, makamaka pomanga ngalande za konkire yokhala ndi mawonekedwe ovuta komanso malo, kusintha pafupipafupi njira, komanso zofunikira kwambiri panjira. Ubwino wake ndi wowonekera bwino. Mzere wachiwiri wa konkire wolimbikitsidwa ndi ngalande umagwiritsa ntchito kapangidwe kosavuta ka chimango cha arch, komwe kumathetsa mavutowa bwino, ndipo nthawi yomweyo, mtengo wa uinjiniya ndi wotsika. Ma trolley ambiri osavuta amagwiritsa ntchito kutsanulira konkire, ndipo trolley yosavuta imadzazidwa ndi magalimoto onyamula konkire, kotero kulimba kwa trolley kuyenera kukulitsidwa kwambiri. Ma trolley ena osavuta amagwiritsanso ntchito Fomu Yopangira Chitsulo, koma amagwiritsabe ntchito ndodo zolukidwa ndipo sasuntha okha. Mtundu uwu wa trolley nthawi zambiri umadzazidwa ndi magalimoto onyamula konkire. Ma trolley osavuta nthawi zambiri amagwiritsa ntchito fomu yopangira zitsulo zophatikizana. Fomu yopangira zitsulo zophatikizana nthawi zambiri imapangidwa ndi mbale zoonda.
Kulimba kwa chitsulo chopangira chitsulo kuyenera kuganiziridwa popanga, kotero mtunda pakati pa ma arches achitsulo suyenera kukhala waukulu kwambiri. Ngati kutalika kwa chitsulo chopangira chitsulo ndi 1.5m, mtunda wapakati pakati pa ma arches achitsulo suyenera kupitirira 0.75m, ndipo cholumikizira cha chitsulo chopangira chitsulo chiyenera kukhazikitsidwa pakati pa kukankhira ndi kukankhira kuti zitheke kukhazikitsa zomangira za chitsulo ndi zingwe za chitsulo. Ngati pampu ikugwiritsidwa ntchito poika chitsulo chopangira chitsulo, liwiro la chitsulo chopangira chitsulo siliyenera kukhala lachangu kwambiri, apo ayi zidzapangitsa kuti chitsulo chopangira chitsulo chophatikizana chisinthe, makamaka pamene makulidwe a lining ndi oposa 500mm, liwiro la chitsulo chopangira chitsulo liyenera kuchepetsedwa. Samalani mukaika chivindikiro ndi kuthira. Samalani kutsanulira konkire nthawi zonse kuti mupewe kutsanulira konkire mutadzaza, apo ayi zidzayambitsa kuphulika kwa nkhungu kapena kusintha kwa trolley.
