② Ua ib qho cim, ntsuas qhov loj me ntawm qhov kev teeb tsa tiag tiag raws li ntu ntu cim, thiab sau nws ntawm daim duab kos duab;Tom qab ntawd, xyuas seb cov kav dej thiab cov khoom siv puas tau muab los ntawm cov chaw tsim khoom, thiab tom qab paub tseeb tias lawv yog lawm, prefabricate raws li qhov ntsuas qhov loj ntawm daim duab kos (Tshuaj kav, fittings, proofreading, pawg naj npawb ntawm cov yeeb nkab seem, thiab lwm yam).
③, qhuav yeeb nkab installation
Lub riser yuav tsum tau nqa los ntawm sab saum toj mus rau hauv qab los txhim kho cov clamps, thiab qhov siab ntawm cov clamps nyob ze ntawm phab ntsa shear yuav tsum yog 1.8 meters, los yog steel composite bracket yuav tsum tau nruab rau ntawm cov yeeb nkab zoo taub hau, thiab cov risers prefabricated yuav tsum tau nruab. nyob rau hauv ib tug hierarchical kev txiav txim raws li tus naj npawb.Ncaj.Cov plugs ib ntus yuav tsum tau muab tso rau ntawm cov ceg kav dej.Kev taw qhia kev teeb tsa ntawm lub riser valve yuav tsum yooj yim rau kev ua haujlwm thiab kho.Tom qab kev teeb tsa, siv lub xaim pendant kom ncaj nws, kho nws nrog clamps, thiab ntsaws lub qhov hauv pem teb hauv kev koom tes nrog kev tsim kho pej xeem.Lub installation ntawm ntau risers nyob rau hauv lub raj zoo yuav tsum tau ntsia nyob rau hauv kev txiav txim ntawm lub sab hauv ua ntej thiab ces sab nraum, thawj loj thiab ces me me.Lub cim ntawm cov kav dej hauv tsev yog lub teeb ntsuab, cov yeeb nkab hluav taws yog xim liab, cov yeeb nkab dej nag yog dawb, thiab cov yeeb nkab hauv tsev yog dawb.
④ Ceg yeeb nkab installation
Rau kev zais daim ntawv thov ntawm ceg kav dej hauv chav dej, qhov ntev ntawm ceg kav dej yuav tsum tau txiav txim siab thiab tom qab ntawd kos thiab muab tso rau.Lub teeb yuag phab ntsa yog slotted nrog lub tshuab slotting, thiab cov kav dej prefabricated tau muab tso rau hauv grooves.Tom qab kev sib tw thiab kev sib tw, siv cov ntsia hlau ntsia hlau los yog cov ntsia hlau los khi cov hlau galvanized hlau los kho cov yeeb nkab;Lub valve thiab detachable qhov chaw yuav tsum tau muab nrog rau kev soj ntsuam qhov;Txhua qhov chaw faib dej yuav tsum tau muab nruab nrog cov yeeb nkab bulkhead nrog qhov ntev ntawm 100mm lossis 150mm, thiab ua kom zoo thiab ua kom zoo, thiab tom qab ntawd ua qhov ntsuas siab ntawm cov kav dej zais.Tom qab qhov kev xeem raug lees txais, cov yeeb nkab zawj yuav tsum tau them nrog cov cement mortar nyob rau lub sijhawm.
⑤, kev ntsuas lub raj xa dej
Cov kav dej uas zais thiab insulated yuav tsum tau kuaj ib tus zuj zus ua ntej muab zais, thiab qhov system yuav tsum tau sim tom qab kev teeb tsa cov kav dej.Hauv kev sim hydraulic, cov huab cua sab hauv yuav tsum tau ntws ua ntej, thiab tom qab ntawd cov dej yuav tsum tau ntim rau hauv cov kav dej.Lub siab maj mam nce mus rau qhov yuav tsum tau ua rau 6 teev.Tsis muaj qhov xau hauv thawj 2 teev.Tom qab 6 teev, lub siab poob qis tsis tshaj 5% ntawm qhov kev sim siab kom tsim nyog.Tus neeg cog lus dav dav, tus saib xyuas thiab cov neeg ua haujlwm cuam tshuam ntawm Party A tuaj yeem raug ceeb toom txog kev lees paub, mus dhau cov txheej txheem vixaj, thiab tom qab ntawd tso dej, thiab sau cov ntaub ntawv ntsuas cov kav dej hauv lub sijhawm.
