Excavation thiab nws cov hom

Excavation - ib tug kab noj hniav uas yog tsim nyob rau hauv lub pob zeb loj tom qab excavation ntawm nws ua ntawm minerals thiab pob zeb.

Nyob ntawm seb lub hom phiaj, ua hauj lwm nrog lub pob zeb raug muab faib ua ntau hom.

Hauj lwm ntawm tus txheej txheem

Underground tsuas yog yus nyob rau hauv uas nws tus ntoo khaub lig no muaj ib tug kaw lub voj voog, hais txog ntawm seb puas muaj mus saib rau ntawm qhov chaw. Nyob rau hauv tas li ntawd mus underground tej hauj lwm yog nqa tawm xws li hais tias mus dhia rau hauv av. Lub qhib excavation muaj qhib lub voj ntoo khaub lig seem.

Thaum lub underground txoj kev ua hauj lwm, nws yuav ua tau:

- tsuas thiab kev tshawb kawm;

- tsuas thiab capital;

- tsuas thiab kev npaj;

- threaded;

- nqi tsev;

- tu.

Excavation, nyob ntawm seb cov lo lus uas, yog ib qho kev tshawb kawm thiab ntau lawm. Tus thawj yog siv rau qhov kev tshawb kawm thiab kev tshawb fawb rau cov tshiab deposits, lub thib ob - rau txoj kev loj hlob ntawm deposits nyob rau hauv kev txiav txim mus rau extract los ntawm cov subsoil minerals. Tu hauj lwm yog subdivided rau hauv pom, kev npaj thiab kev tu.

Kom qhia excavation yog tsim los qhib lub mine thiab kev kawm nkag mus rau mineral kev pab.

Npaj cov ua hauj lwm tau npaj rau txoj kev loj hlob ntawm ib tug kuv teb, thiab nyob rau hauv lub purification txheej txheem ntawm lub ore minerals tawm.

Saib ntawm lub pob zeb thiab txiav txim seb lub tsim los yog kev loj hlob ntawm lub teb yuav ua tau. Tus thawj yog tshaj lub reservoir, lub thib ob - nyob rau hauv lub pov tseg pob zeb.

Excavation yuav raug ncua thiab lub ntim uas yog txiav txim los ntawm tus piv ntawm cov longitudinal seem thiab tus ntoo khaub lig seem thaj tsam ntawm lub kho cov pob zeb. Kev ncua, nyob rau hauv tas li ntawd, muaj kab rov tav, inclined thiab ntsug.

Qhib excavation yog muab faib mus rau hauv trenches, kwj deg, dej, congresses.

tus ntoo khaub lig seem

Tus ntoo khaub lig sectional zoo nyob rau hauv cov kab rov tav txoj kev nyob rau hauv lub pob zeb zog thiab lawv tus mob, cov kev taw qhia thiab lub dag lub zog ntawm cov pob zeb siab, ntev ntawm cov kev pab thiab cov nyiaj them yug qauv.

Arched ntoo khaub lig-sectional zoo muab formulation, uas yog tsis txuas, raws li nws approximates rau cov duab ntawm lub ntuj koov.

Yog hais tias muaj yog tsis muaj sab siab sawmills, ib tus ntoo khaub lig-sectional zoo siv. Nyob rau hauv cov ntaub ntawv no, tso zis yog taag ntoo, zoo los yog espagnolette fastening.

Trapezoidal zoo tiv ob ntsug thiab sab siab. Mounting yog ua los ntawm cov ntoo, precast qhob thiab hlau.

Tus ntoo khaub lig seem kuj yuav yeej, arched thiab arched zoo.

Arched daim ntawv siv nyob rau hauv vaj tse thiab masonry kho.

Arched khawm ris siv nyob rau hauv lub ntsug thiab sab siab ntawm lub pob zeb. Nyob rau hauv cov ntaub ntawv no, txoj kev loj hlob yog muaj zog los ntawm hlau arches.

Thaum tag nrho cov siab yog zoo tshaj plaws haum yeej cross-sectional zoo. Uglespusknye dej yuav kho tsis tau ntawm tag nrho cov. Elliptical ntoo khaub lig seem yog siv, Yog hais tias ib tug ntawm cov siab ntau npaum li cas lwm yam.

Thaum lub sij hawm tsim kho ntawm ntau, hydraulic lug, subways siv elliptical tshuam nrog cov kab rov tav thiab ntsug axis. sectional zoo nyob ntawm lub hom phiaj rau cov uas yog npaj excavation, raws li zoo raws li los ntawm cov tsuas tej yam kev mob. Nyob rau hauv kev, lub zoo vector muaj feem xyuam rau cov nyiaj pab ntau tshaj tej yam siab lub Cheebtsam, uas muaj ib tug uas tig mus axis ntawm lub ellipse.
