中文Qhov puv-kev sib hloov thiab cov txheej txheem kev tsim qauv siv yog hu ua Suptop txoj kev hauv Nyij Pooj. Casing hlau yog siv los tiv thaiv phab ntsa thaum lub qhov txheej txheem tsim. Nws muaj cov yam ntxwv ntawm cov pawg zoo zoo, tsis muaj av nkos muaj kuab paug, lub nplhaib ntsuab, thiab txo cov qhob ua vaj tse filling coeffici. Nws tuaj yeem daws cov teeb meem ntawm qhov sib tsoo, caj dab shrinkage, thiab siab sau coefficage, thiab siab siv pawg siv rau hauv nroog siab sau thiab Karst av.
Pob Zeb Drilling
Kev siv tag nrho cov laum muaj zog torque, lub zog nkag thiab cutter taub hau thiab cutter taub hau, uas tuaj yeem ua tiav cov haujlwm ua haujlwm hauv pob zeb tawv. Lub pob zeb hardness uas tuaj yeem txav tuaj yeem ncav cuag: uniaexial compressive lub zog 150-200MPA; Vim nws cov kev txiav txim siab zoo tshaj plaws, nws tau siv dav hauv kev txiav: High-zog bolts, h piles, hlau yeeb nkab piles thiab lwm yam kev tsim kho steel thiab lwm yam kev ua kom zoo.
Cast-in-qhov chaw tsim los ntawm lub qhov tsua
Kev siv lub rigs muaj kev sib txawv hauv qhov chaw tsim kho qhov chaw tsim txom Nrog nws cov kev ua tau zoo ntsug, tsis siv neeg tswj kev ua tau zoo ntawm drilling ceev, thiab torque siab, nws tuaj yeem yooj yim ua tiav txoj haujlwm drilling los ntawm lub qhov tsua. Thaum nchuav pob zeb ua ke hauv lub qhov tsua, nws tau ua nyob rau hauv lub casing, thiab cov pob zeb nrog ntxiv ntawm cov neeg sawv cev nrawm tsis yooj yim los poob. Thiab vim hais tias lub drilling rig muaj lub zog rub tawm, nws kuj tseem tuaj yeem ncua rub tawm. Yog li ntawd, nws tuaj yeem ua tiav txoj haujlwm ua haujlwm ntawm cam-hauv-qhov chaw piles hauv lub qhov tsua.
Muaj qhov tseeb ntsug
Nws tuaj yeem ua tiav qhov tseeb ntsug ntawm 1/500 (teb drilling rigs tuaj yeem ncav cuag 1/100), uas yog ib qho ntawm cov txheej txheem pawg ntawm cov txheej txheem hauv ntiaj teb.
1. Tag nrho-revolving cas-hauv-qhov chaw siv tshuab kev teeb tsa
Cov cuab yeej tseem ceeb thiab cov khoom siv:
1. Tag nrho-revolving drilling rig: qhov kev sib sau
2. Hlau Casing: Phab Ntsa Kev Tiv Thaiv
3. Lub chaw nres tsheb fais fab: muab hwj huam rau tag nrho-revolving lub cav tseem ceeb
4. Cov tshuaj tiv thaiv diav rawg: muab cov tshuaj tiv thaiv kev tiv thaiv kom tiv thaiv lub cav tseem ceeb los ntawm kev hloov pauv thaum muaj kev sib hloov
5. Chav Haujlwm Chav: Ua Haujlwm Platform, Cov Neeg Ua Haujlwm Qhov Chaw
EUXILIALY KHOOM:
1. Teb Drilling Rig Los yog tseb: Av Extraction, Pob Zeb Nkag Mus, Tiav
2. Yeeb nkab rub tshuab: yeeb nkab tawm, tag nrho kev sib hloov los ua kev lom zem
3. Crawler Crane: Nqa lub tshuab loj, chaw nres tsheb hluav taws xob, cov tshuaj tiv thaiv duav, thiab lwm yam; Muab kev txhawb nqa rau cov tshuaj tiv thaiv diav rawg; Lifting hlau tawb, qhob conduit, thawb av, thiab lwm yam;
4. Excavator: leveling lub xaib, tshem tawm slag, thiab lwm yam.
二.Puv Tag Nrho Kev Sib Hloov Hlau Casing Cast-in-chaw pawg neeg siv khoom
1. Siv kev tsim khoom
Cov haujlwm tseem ceeb ntawm kev tsim qauv npaj yog nce qib. Txij li thaum drilling rig yog loj thiab muaj ntau cov khoom siv uas cuam tshuam, muaj qee yam kev xav tau rau nkag mus raws li raws li cov ntaub ntawv thiab ua haujlwm platform. Yog li ntawd, kev tsim txom cov kev tsim txom los txiav txim siab cov kev tsim kho thiab tsim cov phiaj xwm ua haujlwm xws li txheej txheem kev lag luam hlau tawb ua thiab teeb tsa, hlau tawb, thiab pawg hauv lub hauv paus qhib qhob.
2. Kev Ntsuas thiab Kev Tso Cai
Ua ntej tshaj, ua tib zoo saib xyuas cov chaw ua haujlwm, nce thiab lwm cov ntaub ntawv muaj txiaj ntsig muab los ntawm cov duab kos. Tom qab paub tseeb tias lawv yog qhov tseeb, siv cov chaw nres tsheb tag nrho kom nteg tawm ntawm pawg pawg. Tom qab pawg Pile Center yog nteg tawm, kos ib txoj kab hla kev raws lub nroog pawg rau 1.5m deb thiab ua kom pawg tiv thaiv.
3. Tag nrho-revolving lub cav tseem ceeb hauv qhov chaw
Tom qab lub ntsiab lus tau tso tawm, hoist tag nrho cov chassis, thiab nruab nrab ntawm cov chassis yuav tsum sib txuam nrog qhov chaw nruab nrab ntawm pawg. Tom qab ntawd hoist lub cav tseem ceeb, nruab nws rau ntawm chassis, thiab thaum kawg nruab cov tshuaj tiv thaiv nkhaus.
4. Hoost thiab nruab cov hlau casing
Tom qab lub cav tseem ceeb yog qhov chaw, Hoist thiab nruab cov hlau casing.
5. Ntsuas thiab hloov kho qhov tseeb
Tom qab lub tshuab raj drilling yog nyob rau hauv qhov chaw, ua rau lub cash drilling, thiab nias tseg lub casing thaum tig mus rau tsav lub casing, yog li ntawd lub casing tuaj yeem txav sai rau kev tsim. Thaum Drilling cov hlau hlau, siv tus kav dej los kho qhov tseeb ntawm lub casing hauv cov lus qhia.
6. Casing Drilling thiab Av Extraction
Thaum lub sij hawm lub casing yog drilled mus rau hauv av, ib tug crane siv los tso ib lub thoob sab hauv los ntawm cov av hauv av los ntawm cov av hauv av los yog siv lub rig rig kom rho tawm cov av.
7. Fabrication thiab installation ntawm cov hlau loj
Tom qab drilling rau qhov tsim kom nce, ntxuav lub qhov. Tom qab dhau mus soj ntsuam thiab kev lees paub los ntawm kev tshawb fawb thaj av, kev saib xyuas thiab tog A, nruab tus qauv hlau.
8. Pob zeb ua kom tawg, casing extraction, thiab pawg peting
Tom qab tus hlau tawb hlau tau nruab, ncuav pob zeb ua vaj tse. Tom qab cov qhob tau hliv rau qee qhov siab, rub tawm ntawm lub casing. Lub casing tuaj yeem rub tawm siv cov yeeb nkab rub tshuab lossis kev sib hloov lub cav tseem ceeb.
,. Qhov zoo ntawm kev hloov pauv puv-kev hloov kho:
1 Nws tuaj yeem daws cov chaw tsim kho hauv cov chaw tshwj xeeb, cov haujlwm tshwj xeeb thiab cov suab nrov sib zog, tsis muaj suab nrov thiab muaj kev nyab xeeb siab;
2 tsis siv av nkos, ua haujlwm ua haujlwm yog huv si, tuaj yeem zam kev av nkos nkag mus txhim kho lub zog ntawm cov pob zeb tuav; Tiv thaiv cov av rov qab, tsis kos lub qhov thaiv lub qhov thaum nqa cov laum thiab txo cov khib nyiab hlau, thiab muaj cov khib nyiab tsawg;
3 Thaum tsim lub tshuab khiav tawm drilling, nws tuaj yeem intuitivly txiav txim rau stratum thiab pob zeb tus yam ntxwv;
4 Lub tshuab khiav ceev nrawm nrawm, uas tuaj yeem ncav cuag txog 14m / h rau cov av dav;
5 Qhov tob tob yog loj, thiab qhov siab tshaj plaws tuaj yeem ncav cuag li 80m raws li cov av txheej;
6 Lub qhov ntsug ntawm lub qhov yog ib qho yooj yim rau tsuab, thiab kev sib hloov tau yog li 1/500;
7 Nws tsis yooj yim los cov khoom sib npaug, lub qhov zoo yog siab, hauv qab yog huv, qhov nrawm nrawm, thiab cov av muaj peev xwm tshem tau txog li 30mm;
8 Lub qhov ntawm cov ciav hlau yog cov qauv thiab cov coefficient yog me me. Piv nrog rau lwm txoj kev sib sau, ntau ntawm cov pob zeb ua tau tau txais kev cawmdim.
Lub teb drilling, txheej txheem backiously vim yog cov roj qab av txheej dhau heev thiab muaj cov pob zeb loj.
Qhov kev tsim cov nyhuv ntawm tag nrho cov casing
Kev siv cov pob zeb ua kom tsis muaj tsuas yog siv rau cov pawg ua kom zoo nkauj, tab sis kuj tseem siv tau rau kev tsim kho cov av sai, tab sis kuj tau tshem tawm cov txheej txheem tsheb, subway, thiab pawg tshem tawm.
