(C250) EN124 Txoj Kev Gully Npog Round Ductile Hlau Manhole Npog thiab Ncej

Tus qauv qib yog c250, uas txhais tau hais tias lub manhole npog tseem tuaj yeem siv tau ib txwm thaum qhov chaw nruab nrab raug quab yuam ntawm 250 kN rau tsib feeb.

Nyob rau hauv European EN124 tus qauv, lub siab ntawm lub manhole npog tau muab faib ua 6 tus qauv hauv qab no: A15, B125, C250, D400, E600, F900

Namely: lub siab yog 1.5 tons, 12.5 tons, 25 tons, 40 tons, 60 tons thiab 90 tons.
Ib qho hnyav ntawm 25 tons yog suav tias yog hnyav
Feem ntau siv hauv nroog tsis yog txoj kev loj thiab cov tsheb me me.Raws li ib txwm muaj, nws tuaj yeem siv rau ntawm txoj kev lossis chaw nres tsheb uas tsis muaj tsheb loj.

Kev txhim kho ntawm cov hlau nplaum manhole npog tsis tiav tom qab nws muab tso rau ntawm phab ntsa ntawm lub qhov dej.Ntxiv nrog rau qee qhov kev saib xyuas, nws kuj yuav tsum tau ntxiv dag zog.Qhov no tsuas yog los txhim kho nws txoj kev nyab xeeb thiab kav ntev, thiab ua kom zoo dua.Txhawm rau kom muaj kev nyab xeeb ntawm cov neeg taug kev ntawm txoj kev thiab qhov zoo ntawm lub manhole npog, nws yuav tsum tau ntxiv dag zog li cas?

1. Txiav txim siab qhov siab ntawm lub qhov dej masonry raws li tus qauv tsim ntawm lub voj voog zoo ntxiv.Ua ntej txhim kho cov ncej steel, lub hauv paus qhov yuav tsum tau muab ntxuav.Lub phab ntsa ntawm cov hlau nplaum manhole npog yuav tsum densely poured nrog qis-qib qhob thiab leveled.Lub thav duab steel yuav tsum tau ua tiav rau hauv cov duab plaub, uas zoo ib yam nrog txoj haujlwm ntawm lub taub hau zoo thaum ntsia, thiab cov txheej tiv thaiv ntawm cov hlau bar yuav tsum tau ua kom ntseeg tau.

2. Lub vaj huam sib luag zoo thiab cov hlua hlau manhole npog kev teeb tsa yuav tsum tau nqa tawm ua ntej kev tsim kho ntawm asphalt nto txheej, thiab cov duab thiab qhov loj ntawm lub voj voog zoo yuav tsum tau txiav txim siab raws li qhov loj ntawm lub manhole npog thiab cov qauv tsim. ntawm lub voj voog zoo ntxiv.Feem ntau, nws yog ib lub xwmfab nrog lub taub hau zoo li qhov chaw, thiab lub tshuab txiav yog siv los txiav cov seam txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws raug nquahu kom siv lub tshuab txiav nrog lub qhov dej zoo.

3. Lub pre-embedded bolts tuaj yeem ntsia tau rau tib lub sijhawm raws li lub qhov dej, lossis lawv tuaj yeem muab tso rau hauv pwm.Cov bolts yuav tsum tau muab tso rau hauv vertically, thiab cov txiv ntseej yuav tsum tau nruj ua ntej nchuav cov pob zeb kom zoo txuas nrog cov pob zeb thiab cov qhov tshwj xeeb ntawm lub qhov dej.
