Core Drilling matsime geotechnical kuferefeta

Coring inonzi Drilling, sezvamakaropafadzwa chibooreso kubva mbiru (chinoumba) dombo sanganisika nekuti dombo kuparadza kunoitika chete kumeso mhete. Muzvigadzirwa Drilling turusi rinoumbwa matomu, coring chubhu, chubhu adapters, chibooreso tsvimbo, chibooreso mutungamiriri chubhu uye shwanu. Core Drilling wakatangwa muna 1862 Swiss J. Lesho.

Core mukana nzira iri kuti rinogona akachera zvinenge zvose dombo coring. Kubva chinoumba vanopiwa mukana kuwana mashoko akarurama kupfuura pamusoro Geological chikamu. Core Drilling inoshandiswa mafuta uye gasi kuchera mukati Geological panenge pachivakwa uye Mapping mabasa. Hazvina inokosha nokuda ubanguranyika pamusoro chicherwa deposits, uye rinowanzoshandiswa matsime emvura, muzvidzidzo geochemical uye Geological ouinjiniya kuongorora.

Izvi rworudzi kuchera iri Classified, zvichienderana chinhambwe kubva pasi putswa tudonhwe mabwe dzakadaro kuchera nzira: pakaoma, kunopinda pamwe compressed mhepo, achishandisa Washing mvura (mvura kana madhaka).

Core Drilling rinoshandiswa kuti nokufambisa kwaJehu ivhu rakaoma uye ruhlyakovyh batana matombo. With simba reciprocating kuchera ikakuruma ROP nokuomesa zvichava zvikuru, asi mbiru chinoumba iri akaremara zvikuru, zvichizoita isiriyo mashoko uye zvaasingadi nyaya matsime okugadzira kuitwa akachera. Kana uchityaira pamusoro argillaceous pamatombo kutyora dzavo dzinongoitika marongerwo uye mwando nokuda kudziyisa chinoumba uye deformation (Curling, kana ndichinanavira). Drilling pakaoma weathered pamatombo zvinopawo anotsausa mashoko pamusoro mwero weathering nematombo, chikanganiso chikuru ndechokuti zvinogona (mukati 0.5 m) ari tsanangudzo wokutanga miganhu, saka munhu akaturikidzana nedombo ane goho pamusoro 0.25 kana kupfuura (kusvika 0.5 M ) chinogona kusiyiwa (asina kunyorwa) panguva zvemakore kuti uyewo zvaasingadi geotechnical kuferefeta.

Core Drilling inoshandiswa kubvisa mhepo kana uchityaira dombo Weathered, jecha uye ivhu yakatsiga uye permafrost. Kodzera kushandisa Flushing mvura padombo zvakaoma uye irambe poluskalnyh namatombo. Nzira iyi inopa unhu hwakanaka geotechnical ruzivo.

Core Drilling weathered matombo kuti zvakanakisisa kuchengetedza chinoumba rinoitwa pombi kaviri Mbiru rinoshandisirwa kana ejector coring projectiles. Species nyoro (kukwira Category III), svikiro pokuoma (chikamu IV -V) uye yakasimba (V -VIII) akachera carbide korona. Nokuti dombo rakaoma (IX - XII) uye ubatanidzwewo hwakasimba nedhaimani rinoshandiswa uye bara korona. Kana makirisito kuchera kunokosha kuchengeta kuchera muoti - razruschayuschy axial mutoro pamusoro chokushandisa, projectile kukurumidza (Zvak / Nha) uye pakuitika kubvumira kuti Flushing vhoriyamu (l / Nha) mvura chikafu.
