Rau qhov chaw xaiv qhov teeb meem nyob rau hauv lub sij hawm thaum ntxov ntawm kev tsim kho ntawm immersed hlab ua los ntawm lub tsev blocks, nws yog tsim nyog los xaiv ib tug kuj qeeb dej ntws thiab nqaim dej nto dav raws li txoj kev pipeline. Nws tseem yog ib qho tsim nyog yuav tsum tau xav txog tag nrho cov dej hauv qab dej geological kom txo cov kev tsim kho nyuaj thiab txo cov nqi tsim kho. Kev tsim kho cov kav dej-immersed raj yuav tsum tau ua tib zoo saib xyuas kev tsim kho. Txhua qhov txuas tseem ceeb heev. Koj tsuas yog yuav tsum tau ua tib zoo saib xyuas cov haujlwm ua ntej kev sib txuas ntawm txhua qhov txuas, xws li kev ntsuas, qhov chaw thiab kev teeb tsa kev tswj hwm, cov khoom siv vuam tswj, kev tiv thaiv corrosion, thiab immersed raj Shen tso tawm ceev, sib npaug, thiab lwm yam kev tswj. Txoj kev tsim kho ntawm cov kav dej hauv qab: Thaum hla cov dej ntws thiab cov dej ntws nrog qhov dav me me, cov yeeb nkab jacking txoj kev los yog cov ntaub thaiv npog tuaj yeem siv rau kev tsim kho.
Muaj thaum hla pas dej los yog straits:
(1) Floating daim ntawv thov txheej txheem. Cov kav dej yog tsim, ua tiav, thiab sib sau ua ke rau hauv cov kav dej hauv av, ntab mus rau kev tso, cov pob qij txha ntawm cov kav dej yog welded rau ntawm lub nkoj ua haujlwm, thiab tom qab ntawd cov kav dej tau poob rau hauv qhov chaw. Kev tso dej hauv qab thiab kev sib txuas ntawm cov kav dej yog txhua yam ua haujlwm los ntawm cov neeg dhia dej. Divers siv cov cuab yeej kev sib txuas lus los sib txuas lus nrog lub nkoj crane, kho qhov chaw nres nkoj ntawm lub nkoj, thiab kev ua haujlwm ntawm cov boom ntawm lub nkoj kom lub tog raj xa dej tau raws li cov kav dej tso.
(2) Underwater towing yeeb nkab tso: Thaum nws yog ib qho nyuaj rau xaiv buoyancy rau ib tug ntev yeeb nkab seem, nws muaj peev xwm towed rau hauv qab dej. Nws tsis tshua muaj kev cuam tshuam los ntawm cua nthwv dej thiab dej ntws thaum thauj, thiab kev ua haujlwm muaj kev nyab xeeb. Nws tsis tas yuav tswj lub nkoj, tab sis lub hauling horsepower kuj loj.
Lub fabrication thiab shaping ntawm lub raj xa dej yog nqa tawm ua ke nrog rau kev khawb ntawm lub trench, los yog nws yog tsim thiab assembled ua ntej. Cov kav hlau sib sau ua ke tau raug rau cov kev ntsuas hydrostatic los ntawm ntu, thiab kev kho cov kab mob ntawm cov yeeb nkab tsuas tuaj yeem ua tiav tom qab dhau qhov kev xeem.
Lub raj xa dej yog ntab tag nrho, thiab cov nozzles ntawm ob qho kawg ntawm cov kav dej yog thaiv los ntawm thaiv cov phiaj ua ntej tso tawm, thiab cov kav dej nkag, cov kav dej, thiab cov li qub tau teeb tsa rau ntawm daim phiaj thaiv.
Kev thaiv cov phab ntsa hauv qab dej: Nws yog siv ntau dua los thaiv cov kav dej loj thiab nruab nrab los ntawm kev tsim cov phab ntsa cib nrog cov cement mortar los yog cov cement av nplaum ua cov khoom siv cement. Nws muaj qhov zoo ntawm kev tshem tawm cov khoom yooj yim thiab cov nyhuv sealing zoo, tab sis qhov tsis zoo yog tias nws nyuaj rau dismantle. Feem ntau, muaj ob hom dej tsis muaj sealing thiab dej puv sealing. Thaum lub sij hawm tsim kho, kev saib xyuas, lossis tshuaj xyuas cov kav dej, feem ntau yuav tsum tau thaiv cov kav dej ib ntus uas hla dej, txwv tsis pub, cov dej num no ua tsis tau. Cov kav dej tsis tuaj yeem txiav tawm cov dej los yog roj tsuas yog kaw lub valve ntawm cov kav dej lossis cov kav dej.
Immersion yeeb nkab siv rau steel kav hla dej ntws: A3 steel ncaj seam coil vuam yog siv rau kev tsim cov yeeb nkab, thiab cov yeeb nkab fittings yuav tsum tau tsim raws li lub teb chaws tus qauv "S311".
Kev tiv thaiv ib puag ncig thiab kev tswj hwm kev huv ntawm kev tsim vaj tse nyob rau ntawm qhov chaw tsim kho tshuab ntawm cov khoom siv hauv qab dej rau hla cov kav dej:
1. Lub chaw tsim kho yog nruj me ntsis raws li cov cai ntawm kev tsim kho vaj tse, thiab qhia cov neeg ua haujlwm kom paub meej ua raws li kev tiv thaiv ib puag ncig thiab kev tswj hwm kev huv huv.
2. Nws yog qhov tsim nyog rau kev tso dej tob tob hauv cov kav dej, xws li tso cov kav dej loj hauv hiav txwv. Yog hais tias lub raj xa dej yog prefabricated nyob rau hauv seem, qhov ntev dragging yuav tsum tau ntxiv mus rau seem-by-section interface ntawm dragging pipeline. Qhov ntev ntawm lub raj xa dej rub ib zaug tuaj yeem ncav cuag kaum meters.
3. Cov yeeb nkab tso rau ntawm cov yeeb nkab-ntev nkoj: thauj cov kav dej mus rau cov yeeb nkab-ntev nkoj los ntawm lub nkoj thauj, thiab tom qab txuas cov yeeb nkab seem ntawm cov yeeb nkab-ntev nkoj, txo lawv mus rau hauv qab ntawm cov dej raws li cov slides, cov yeeb nkab. brackets, thiab lwm yam khoom siv ntawm cov yeeb nkab tso nkoj. tus
Ib ntu ntawm cov yeeb nkab yog muab los ntawm nkoj. Txawm tias siv txoj kev twg los xij, qhov kev ntxhov siab ntawm cov raj xa dej yuav tsum tau kuaj xyuas raws li qhov sib txawv ntawm kev ntxhov siab. Yog tias qhov kev ntxhov siab loj dhau lawm, yuav tsum tau ua raws li kev ntsuas kev txhawb nqa.
Ob txoj kev tso rau folded underwater pipelines:
1. Muab tso rau hauv qab dej;
2. faus rau hauv qab dej trench; thaum muab faus rau hauv qab dej trench, qhov tob ntawm cov yeeb nkab ru tsev nyob rau hauv lub trench feem ntau yog 3-4 zaug ntawm txoj kab uas hla ntawm cov yeeb nkab los tiv thaiv cov nkoj los ntawm kev tawg thiab dej scouring.
Txoj kev tsim kho: Thaum hla cov dej ntws thiab cov dej ntws nrog qhov dav me me, txoj kev siv cov yeeb nkab jacking los yog cov ntaub thaiv npog tuaj yeem siv rau kev tsim kho.
Muaj thaum hla pas dej los yog straits:
① Floating daim ntawv thov txheej txheem. Cov kav dej yog tsim thiab ua tiav rau hauv av, welded rau hauv cov yeeb nkab feem ntau pua meters ntev, thiab tom qab ntawd rub tawm hauv qab lossis dej saum npoo av nrog cov khoom siv traction (winch, nkoj, thiab lwm yam), thiab cov kav dej txuas txuas txuas ntxiv mus rau ntawm ntug dej ua ke kom txog rau thaum lub caij nplooj ntoo hlav. pipeline yog rub mus rau qhov predetermined nteg txoj hauj lwm.
Lub qhov dej hauv qab uas tsim los ntawm txoj kev immersed raj muaj ntau qhov zoo dua li txoj kev tiv thaiv. Cov tseem ceeb yog: yooj yim los xyuas kom meej kev tsim kho. Vim hais tias cov yeeb nkab seem yog prefabricated, qhov kev tsim vaj tse yog siab, thiab nws yog ib qho yooj yim rau kev ntsuas dej; cov yeeb nkab ntu yog ntev, nrog ob peb pob qij txha, thiab cov dej xau tau txo qis heev, thiab cov seam tsis xau los ntawm kev siv cov txheej txheem hydraulic siab sib txuas.
