中文Txoj kev sib hloov puv thiab puv-casing yog hu ua SUPERTOP txoj hauv Nyij Pooj. Hlau casing yog siv los tiv thaiv phab ntsa thaum lub sij hawm tsim lub qhov. Nws muaj cov yam ntxwv ntawm pawg zoo, tsis muaj av nkos, lub nplhaib ntsuab, thiab txo cov qhob ntim coefficient. Nws tuaj yeem daws tau qhov teeb meem ntawm qhov tawg, lub caj dab shrinkage, thiab siab filling coefficient uas tshwm sim thaum cov txheej txheem zoo tib yam yog siv rau kev tsim cov cam khwb cia hauv qhov chaw hauv nroog siab sau thiab karst landforms.
Pob zeb drilling
Kev sib hloov tag nrho muaj qhov muaj zog torque, lub zog nkag thiab lub taub hau txiav, uas tuaj yeem ua tiav cov haujlwm tsim kho hauv cov pob zeb nyuaj. Lub pob zeb hardness uas tuaj yeem drilled tuaj yeem ncav cuag: uniaxial compressive zog 150-200MPa; vim nws txoj kev ua tau zoo tshaj plaws, nws tau siv dav hauv kev txiav: pob zeb ua pob zeb, lub zog siab bolts, H pawg, steel yeeb nkab pawg thiab lwm yam kev tsim kho.
Cast-in-place pawg tsim los ntawm qhov tsua
Tag nrho cov rotary drilling rigs muaj qhov zoo sib xws hauv qhov tsua kev tsim kho dua lwm cov txheej txheem kev tsim kho: lawv tsis tas yuav rov qab ntim cov pob zeb lossis cov casing ntxiv. Nrog nws tus kheej zoo ntsug hloov kev ua tau zoo, tsis siv neeg tswj kev ua tau zoo ntawm drilling ceev, drilling siab, thiab torque, nws tuaj yeem yooj yim ua tiav cov haujlwm drilling los ntawm lub qhov tsua. Thaum nchuav cov pob zeb hauv lub qhov tsua, nws yog ua tiav hauv lub casing, thiab cov pob zeb ua ke nrog qhov sib ntxiv ntawm tus neeg sawv cev ceev ceev tsis yooj yim poob. Thiab vim hais tias lub pob zeb drilling muaj zog rub, nws tuaj yeem ncua kev rub. Yog li ntawd, nws tuaj yeem ua tiav txoj haujlwm tsim kho ntawm cov cam khwb cia hauv qhov chaw hauv lub qhov tsua.
High ntsug raug
Nws tuaj yeem ua tiav qhov tseeb ntawm 1/500 (rotary drilling rigs tuaj yeem ncav cuag 1/100), uas yog ib qho ntawm cov txheej txheem hauv paus nrog qhov tseeb tshaj plaws ntsug hauv ntiaj teb.
1. Puv-revolving cam khwb cia-nyob rau hauv-qhov chaw pawg tsim kho machinery configuration
Cov khoom siv tseem ceeb thiab cov khoom siv:
1. Puv-revolving drilling rig: qhov sib sau
2. Hlau casing: phab ntsa tiv thaiv
3. Chaw nres tsheb fais fab: muab lub zog rau lub cav loj loj puv puv
4. Reaction diav rawg: muab cov tshuaj tiv thaiv quab yuam los tiv thaiv lub cav tseem ceeb ntawm kev hloov pauv thaum lub sijhawm hloov pauv tag nrho
5. Chav ua haujlwm: kev ua haujlwm platform, cov neeg ua haujlwm chaw ua haujlwm
Cov cuab yeej pabcuam:
1. Rotary drilling rig los yog grabbing: av extraction, pob zeb nkag, qhov ntxuav
2. Yeeb Nkab jacking tshuab: cov yeeb nkab rho tawm, tag nrho kev sib hloov los ua haujlwm txaus
3. Crawler crane: nqa lub tshuab tseem ceeb, chaw nres tsheb fais fab, tshuaj tiv thaiv diav rawg, thiab lwm yam .; muab kev txhawb nqa rau cov tshuaj tiv thaiv diav rawg; lifting steel tawb, qhob conduit, grabbing av, thiab lwm yam.;
4. Excavator: leveling qhov chaw, clearing slag, thiab lwm yam.
二.Tag nrho rotation steel casing cam khwb cia-hauv-qhov chaw pawg txheej txheem
1. Kev npaj kev tsim kho
Lub luag haujlwm tseem ceeb ntawm kev npaj kev tsim kho yog txhawm rau txhim kho qhov chaw. Txij li thaum lub drilling rig yog qhov loj thiab muaj ntau yam khoom siv cuam tshuam, muaj qee yam yuav tsum tau muaj rau kev nkag mus thiab cov chaw ua haujlwm. Yog li ntawd, kev npaj kev tsim kho yuav tsum xav txog cov kev tsim kho thiab cov dav hlau ua haujlwm uas yuav tsum tau ua rau kev ua haujlwm xws li pawg hauv paus steel tawb ua thiab tsim khoom, kev thauj mus los slag, steel tawb nqa thiab kev teeb tsa, thiab pawg hauv paus pob zeb.
2. Kev ntsuas thiab kev teeb tsa
Ua ntej, ua tib zoo tshuaj xyuas cov kev tswj xyuas, qhov siab thiab lwm cov ntaub ntawv cuam tshuam los ntawm kev tsim cov duab kos. Tom qab paub meej tias lawv yog lawm, siv tag nrho cov chaw nres tsheb los nteg tawm qhov chaw pawg. Tom qab qhov chaw nruab nrab tau tso tawm, kos ib txoj kab hla ntawm pawg pawg mus rau 1.5m deb thiab ua ib qho kev tiv thaiv pawg.
3. Puv-revolving lub ntsiab cav nyob rau hauv qhov chaw
Tom qab lub ntsiab lus raug tso tawm, tuav lub chassis tag nrho, thiab qhov nruab nrab ntawm lub chassis yuav tsum coincide nrog qhov nruab nrab ntawm pawg. Tom qab ntawd hoist lub ntsiab cav, nruab rau ntawm lub chassis, thiab thaum kawg nruab cov tshuaj tiv thaiv diav rawg.
4. Hoist thiab nruab cov hlau casing
Tom qab lub ntsiab cav nyob rau hauv qhov chaw, hoist thiab nruab lub steel casing.
5. Ntsuas thiab kho verticality
Tom qab lub tshuab drilling yog nyob rau hauv qhov chaw, ua rotary drilling, thiab nias rau hauv lub casing thaum tig los tsav lub casing, thiaj li hais tias lub casing yuav tau sai drilled rau hauv lub tsim. Thaum drilling cov hlau casing, siv cov kav dej los kho qhov ntsug ntawm lub casing hauv XY cov lus qhia.
6. Casing drilling thiab av extraction
Thaum lub casing yog drilled rau hauv av, ib tug crane yog siv los tso ib lub thoob nyob rau hauv lub puab phab ntsa ntawm lub casing mus rau hauv qab ntawm lub qhov kom rho tawm av los ntawm lob los yog siv ib tug teb drilling rig mus rho tawm av.
7. Fabrication thiab installation ntawm steel tawb
Tom qab drilling mus rau qhov siab tsim, ntxuav lub qhov. Tom qab dhau qhov kev tshuaj xyuas thiab kev lees paub los ntawm thaj av daim ntawv ntsuam xyuas, kev saib xyuas thiab Party A, txhim kho lub tawb steel.
8. Qhob pouring, casing extraction, thiab pawg pouring
Tom qab lub tawb steel yog ntsia, ncuav pob zeb. Tom qab lub pob zeb tau nchuav rau ib qhov siab, rub tawm lub casing. Lub casing tuaj yeem rub tawm los ntawm kev siv lub tshuab yeeb nkab jacking lossis lub tshuab ua haujlwm puv puv.
三,. Qhov zoo ntawm kev siv tag nrho kev sib hloov:
1 Nws tuaj yeem daws cov teeb meem kev tsim kho hauv cov chaw tshwj xeeb, kev ua haujlwm tshwj xeeb thiab cov txheej txheem nyuaj, tsis muaj suab nrov, tsis muaj kev vibration thiab kev ua haujlwm siab;
2 Tsis siv cov av nkos, qhov chaw ua haujlwm huv si, tuaj yeem zam cov av nkos nkag mus rau hauv cov pob zeb, uas yog qhov tsim nyog rau kev txhim kho lub zog ntawm cov pob zeb rau cov hlau tuav; tiv thaiv cov av rov qab, tsis khawb lub qhov phab ntsa thaum nqa lub laum thiab txo qis hauv lub tawb steel, thiab tsis muaj cov khib nyiab tsawg dua;
3 Thaum tsim lub drilling rig, nws muaj peev xwm txiav txim siab lub stratum thiab pob zeb yam ntxwv;
4 Lub drilling ceev ceev, uas tuaj yeem ncav cuag li 14m / h rau cov txheej av dav dav;
5 Qhov tob qhov tob yog qhov loj, thiab qhov siab tshaj plaws tuaj yeem ncav cuag li 80m raws li cov av txheej txheej;
6 Lub verticality ntawm lub qhov yog yooj yim los tuav, thiab lub verticality yuav raug rau 1/500;
7 Nws tsis yooj yim rau kev tsim lub qhov tawg, lub qhov zoo yog qhov siab, hauv qab yog huv si, ceev ceev, thiab cov khib nyiab tuaj yeem tshem tawm txog li 30 hli;
8 Lub qhov taub yog tus qauv thiab cov coefficient filling me me. Piv nrog rau lwm txoj hauv kev tsim lub qhov, qhov loj ntawm pob zeb tuaj yeem cawm tau.
Lub qhov rotary drilling qhov tau tawg loj heev vim tias cov av rov qab txheej yog tuab heev thiab muaj cov pob zeb loj.
Qhov-forming nyhuv ntawm tag nrho cov casing
Tag nrho cov rotary drilling rigs tsis yog tsuas yog siv rau pawg hauv paus kev tsim kho nyob rau hauv ntau yam complex strata xws li quicksand, karst landforms, thiab super-high backfill, tab sis kuj siv tau rau tom pawg tsim, subway steel kab, thiab pawg tshem tawm.
