Tsim thiab tsim los ntawm peb lub tuam txhab, hydraulic tunnel lining trolley yog ib lub tshuab zoo tagnrho rau kev tsim cov formwork ntawm txoj kev tsheb ciav hlau thiab txoj kev loj. Tsav los ntawm lub cev muaj zog hluav taws xob, nws muaj peev xwm txav mus los thiab taug kev ntawm nws tus kheej, nrog rau lub tog raj kheej hydraulic thiab lub tshuab ntsia hlau siv los tso thiab rov qab tau cov formwork. Lub trolley muaj ntau qhov zoo hauv kev ua haujlwm, xws li tus nqi qis, cov qauv txhim khu kev qha, kev ua haujlwm yooj yim, kev ceev ceev ntawm cov kab thiab qhov av zoo.
Lub trolley feem ntau yog tsim los ua hom steel arch, siv cov qauv hlau sib xyaw ua ke, tsis muaj kev taug kev tsis siv neeg, siv lub zog sab nraud los rub, thiab cov qauv detachment yog txhua yam ua haujlwm tes, uas yog kev siv zog ntau. Hom trolley lining no feem ntau yog siv rau kev tsim kho qhov av luv luv, tshwj xeeb tshaj yog rau kev tsim kho qhov av nrog cov dav hlau nyuaj thiab qhov chaw geometry, kev hloov pauv ntau zaus, thiab cov txheej txheem nruj. Nws qhov zoo yog qhov pom tseeb dua. Qhov thib ob qhov av reinforced concrete lining txais yuav tus qauv yooj yim arch, uas daws cov teeb meem no zoo, thiab tib lub sijhawm, tus nqi engineering qis. Feem ntau ntawm cov trolleys yooj yim siv cov pob zeb cuav pouring, thiab lub trolley yooj yim lining yog puv nrog cov tsheb thauj khoom conveying, yog li qhov rigidity ntawm lub trolley yuav tsum tau txhawb nqa tshwj xeeb. Qee lub trolleys yooj yim lining kuj siv cov hlau formwork, tab sis lawv tseem siv cov pas nrig threaded thiab tsis txav mus los tsis siv neeg. Hom trolley no feem ntau yog puv nrog cov tsheb thauj khoom conveying. Cov trolleys yooj yim lining feem ntau siv cov hlau formwork ua ke. Cov hlau formwork ua ke feem ntau yog ua los ntawm cov phaj nyias.
Yuav tsum xav txog qhov ruaj khov ntawm cov hlau formwork hauv cov txheej txheem tsim, yog li qhov sib nrug ntawm cov hlau arches yuav tsum tsis txhob loj dhau. Yog tias qhov ntev ntawm cov hlau formwork yog 1.5m, qhov nruab nrab ntawm cov hlau arches yuav tsum tsis txhob loj dua 0.75m, thiab qhov sib koom ua ke ntawm cov hlau formwork yuav tsum tau teeb tsa ntawm qhov thawb thiab thawb kom yooj yim rau kev teeb tsa cov formwork fasteners thiab formwork hooks. Yog tias lub twj tso kua mis siv rau kev txhaj tshuaj, qhov ceev ntawm kev txhaj tshuaj yuav tsum tsis txhob ceev dhau, txwv tsis pub nws yuav ua rau deformation ntawm cov hlau composite formwork, tshwj xeeb tshaj yog thaum lub thickness ntawm lining ntau dua 500mm, qhov ceev ntawm kev txhaj tshuaj yuav tsum qeeb. Ceev faj thaum capping thiab nchuav. Them sai sai rau kev nchuav cov pob zeb txhua lub sijhawm kom tiv thaiv cov pob zeb nchuav tom qab sau, txwv tsis pub nws yuav ua rau pwm tawg lossis deformation ntawm lub trolley.
