Cov txheej txheem rov qab DTH rauj drilling txheej txheem yog ib feem tseem ceeb ntawm Multi-Tech cua drilling tshuab, thiab tseem ceeb tshaj, nws yog ib qho kev tawg loj ntawm huab cua drilling tshuab.Nws tau ua ke nrog DTH cuam tshuam rau kev tawg pob zeb, yaug qhov nruab nrab rov qab ncig thiab txuas ntxiv mus rau peb txoj kev drilling siab heev rau hauv ib qho system, thiab ib txwm nws tau dhau los ua kev sib xyaw ua ke high-tech drilling cov tswv yim.Lub hollow-dhau DTH, rov qab ncig me ntsis, thiab dual-phab ntsa drilling cuab yeej yog tsim los ntawm qhov chaw nruab nrab, tom qab ntawd cov dej ntws nruab nrab nrog rau qhov chaw nruab nrab los tsim cov kev rov qab, yog li nws tau paub txog kev thauj mus los hauv cov txheej txheem ntawm drilling thiab zoo daws qhov teeb meem ntawm orifice plua plav paug.Tam sim no, qhov kev siv thev naus laus zis no tau txhim kho sai nrog rau daim ntawv thov uas tau nthuav dav zuj zus, thiab nws tau txais cov ntawv thov zoo hauv kev lag luam drilling xws li kev tshawb nrhiav geological core, dej zoo drilling thiab foundation engineering.
Cov thev naus laus zis tseem ceeb ntawm kev thim rov qab DTH rauj drilling
1. Cov qauv tsim ntawm hollow-dhau DTH rauj
Tus yuam sij ntawm kev tsim qauv ntawm DTH rauj yog qhov hollow pore tsim.Lub hauv paus ntawm rauj tag nrho qhov chaw yog lub hollow-los ntawm raj qauv.Lub hollow-los ntawm pore thiab lub pre-thiab-post air chambers yog tag nrho kaw, thiab lub puab raj tsim lub hollow-los ntawm pore yog hla txhua qhov chaw, nrog rau nws sab sauv txuas nrog lub puab raj ntawm laum yeeb nkab thiab sab hauv qab. tsev grafting drilling me ntsis los ua tus rov qab ncig channel.Nyob rau tib lub sijhawm, lub raj sab hauv muaj cov roj faib ua haujlwm.
2 Computerized emulation ntawm DTH rauj
Ua ntej, siv cov kev tshawb xav thiab cov qauv lej los tsim cov qauv lej.Thib ob, raws li qhov sib txawv ntawm qhov sib txawv txoj kev xav los txhim kho lub khoos phis tawj software.Thaum kawg, nws tau ua tiav lub computerized emulation ntawm rauj dynamic txheej txheem, piston reciprocating tsab ntawv tsa suab txoj cai thiab rauj kev ua tau zoo tsis.Nrog lub khoos phis tawj tau pab tsim qhov zoo tshaj plaws, qhov ntsuas qhov ntsuas qhov tseeb yog qhov ua tau zoo nrog lub computerized emulation tsis.Kev ua haujlwm ua haujlwm tau zoo, thiab cov cua sov ua haujlwm zooefficiency yog siab, thiab yog li tsim ntawm rauj ua scientific.Nws hloov cov txheej txheem tsim ib txwm, ua kom lub voj voog txoj kev loj hlob sai, txuag cov nqi tshawb fawb thiab ua kom zoo rau kev ua haujlwm rauj.
