Keʻano TRD . Kaʻina Hana

1、Principle: Ma hope o ka ʻoki ʻia ʻana o ka mea hana ʻoki kaulahao a hoʻomau i ka hohonu o ka hoʻolālā ʻana, ua hoʻokuʻu ʻia ʻo ia me ka slurry sima e hana i ka mānoanoa like ʻole a me ka paia sima ʻole;

2、E hoʻokomo i nā mea kumu (he kila H-like, etc.) i loko o ka paia hui ʻana o ka sima o ka mānoanoa like e hana ai i ka hoʻopaʻa ʻana a me ka hale hoʻomaha wai.

Keʻano TRD . Nā hiʻohiʻona a me ka laulā1. Ua pili i ka palolo, one, iliili a me ka iliili papa, a me ka maikai applicability i loko o dense one papa me ka 30-60 maʻamau penetration waiwai a palupalu pōhaku me ka uniaxial compressive ikaika saturated 'aʻole ma mua o 10 MPa.2. Hiki i ka hohonu o ka pā i hoʻopau ʻia ke hiki i 70 mau mika, a ʻaʻole e ʻoi aku ka nui o ka neʻe ʻana o ka verticality ma mua o 1/250 (inā ʻaʻole ʻoi aku ka nui o ka TRD verticality deviationist ma mua o 1/300 i ka wā e hoʻohana ʻia ai e hoʻoikaika i nā paia o loko a me waho. ka paia honua);

3.Wall mānoanoa 550-950 mm;

4. Ua hui like ka sima, a me ka ikaika compressive unconfined 0.5-2.5MPa;

5. He maikaʻi ka pale wai o ka pā, a hiki i ka coefficient permeability ke hiki i ka 1 × 10-6 cm / s i ka 1 × 10-7 cm / s i ka lepo one;

6. Hiki ke hoʻonohonoho pono ʻia ka spacing o nā profile interpolated me ka spacing like, a ʻoi aku ka like o ka rigidity o ka pā;

7. ʻAʻole ʻoi aku ka kiʻekiʻe o nā mīkini hana ma mua o 12 mika. a he haʻahaʻa ke kikowaena o ka umekaumaha o ke kahua kūkulu, me ka paʻa maikaʻi.

Inā loaʻa iā ʻoe nā koi e pili ana i nā rigs drilling rotary, e ʻoluʻolu e kelepona no nā kikoʻī hou aku a me ke kūkākūkā.
