Kuvakwa kwetunnel kwagara kuri kwepamusoro pezvirongwa zvekuvaka, uye kwakaoma kuvaka. Pamberi pemakore ekuma1960, musanganiswa wekuchera nekuputika wakashandiswa mukuvakwa kwematanho. Izvo zvisingabatsiri zveiyi nzira zviri pachena, kuchengetedzwa kwekuputika hakuzivikanwi, huwandu hukuru hwekusvibiswa hunogadzirwa, uye chimiro chekuputika kwemugero hachina kurongeka uye hachikwanisi kunyatsodzorwa. Mushure memakore ekuma1960, mwero wekuvaka wemichina wakavandudzwa zvakanyanya. Kushandiswa kweroadheader kwachinja zvachose kuchera uye kuputika maitiro ekuchera tunnel. Mazuva ano, midziyo yakanakisa inosanganisirwa muinjiniya yetunnel, uye mucheki wedhiramu nematombo akaona zvigadzirwa zvenharaunda yeYichen zvine mashandiro akanaka mukuvaka tunnel.

Mazino ekucheka ari padhiramu rekucheka anodhumhana nepamusoro pekuvaka uye kucheka matombo evhu nematombo semhashu, zvichipa nzira itsva uye yehupfumi yekuvaka yekuchera tunnel. Kubva muna Gumiguru 2010, Yichen yekugaya nekuchera muchina wanga wakajeka muinjiniya yemugero.

MuHutubi, Shaanxi, VaLi nomwanakomana wavo vakaita chibvumirano chokuchera mugero wakareba mamita matanhatu uye wakafara mamita mashanu. Mr. Li vakashandura boom yeHitachi 200 excavator kune ruoko rwakatwasuka uye akaisa YF-20RW drum cutter muYichen nharaunda yekuchera tunnel. Kana iri sandstone, sedimentary rock uye silty dombo mukati memugero, kumhanya kwekutyaira kwedhiramu rekucheka kunosvika 10m zuva rega rega, uye kushanda kwekugaya kwakakwira zvakanyanya. Nerubatsiro rweYichen drum cutter, chirongwa chakapedzwa mumazuva makumi mana, ichipfupisa zvakanyanya nguva yekuvaka.

Yichen Rock Saw inogona Kuita Zviri nyore neTunnel Face Kucheka

Munguva yetunneling, dombo rakaoma kwazvo rinosangana dzimwe nguva. Nekuda kwekuoma kwakanyanya, kushandiswa kwedhiramu yekucheka hakugone kuita zvinodiwa pakushanda. Panguva ino, rock saw ichasarudzwa yekucheka. Iyo dombo saw inogadzirwa neyakagadzirwa diamond zvinhu, izvo zvinokwana kubata nedombo rakaoma. Nzira uye kudzika kwekucheka kuchaongororwa maererano nemamiriro chaiwo edombo uye chirongwa chekuvaka chichagadziriswa.

Tichitora Xiamen tunnel project muFujian Province semuenzaniso, China Railway yakasangana negranite tunnel face panguva yekuchera, saka bato rekuvaka rakaisa Yichen YS-20SS pane 20 ton excavator yekucheka basa, ndokuigogodza nenyundo inopwanya mushure mekucheka, kuitira kuti uone kucherwa kwechiso chedombo rakaoma.
