Ⅰ. Rusvingo runodzivirira madhaka rwakaumba mirwi
Forward and reverse circulation bored piles: Forward circulation is that the flushing fluid inotumirwa kuzasi kwegomba nepombi yedhaka kuburikidza netsvimbo yekuchera, yozodzokera pasi kubva pasi pegomba; reverse circulation flushing fluid yakanyatsopesana nenzira yekutenderera mberi.
1 、 Mamiriro evhu anoshandisika: ivhu revhu, silt, jecha rakanaka, jecha riri pakati nepakati, jecha rakaomarara, ivhu rine matombo mashoma nehurungudo (zviri pasi pe20%).
2 、 Application scope: kuvaka engineering; mugwagwa uye mainjiniya emabhiriji; mainjiniya emagetsi.
Percussive DrillingHoleKuzadzaMurwi:Mechanical drilling, simbi pombi kusvinwa kana kuchera kwevanhu kuita mirwi makomba mukati
nheyo ivhu.
1,Inoshandaivhumamiriro: ivhu revhu, ivhu rehupfu, ivhu rejecha, ivhu rekuzadza, ivhu rematombo uye matombo akaomeswa.
2, Chikumbiro chiyero:engineering engineering; mugwagwa uye mainjiniya emabhiriji; mainjiniya emagetsi.
(2)RotaryHoleKuzadzaMurwi:Uchishandisa chibooreso kutenderedza chibooreso muvhu, gomba rekupedzisira rakaumbwa ndiro buri rinotenderera rinozadza.
1,Inoshandaivhumamiriro: ivhu revhu, ivhu rehupfu, ivhu rejecha, ivhu rekuzadza, ivhu rematombo uye matombo akaomeswa.
2, Chikumbiro chiyero:inoshandiswa mukuvaka kwemanisipala, mugwagwa mukuru uye bhiriji, maindasitiri uye kuvaka kwevagari, pasi pevhu
diaphragm rusvingo, kuchengetedza mvura, kudzivirira seepage, kudzivirira materu uye kumwe kuvaka nheyo.
Ⅱ. Dry-basa akafinhwa mirwi
(1) Yakareba Auger Bored Murwi:Dhobora buri neauger drilling rig, chenesa pasi pegomba kusvika pakadzika dhizaini, isa pasi keji yekusimbisa, wodira kongiri mukoramu.
1, Mamiriro evhu anoshanda: ivhu revhu riri pamusoro petafura yemvura, ivhu rejecha uye yekugadzira inozadza ivhu risiri rakaomeswa nevhu, zvine simba.
weathered rock.
2, Chiyero chekushandisa: zvivakwa zvehurumende uye zvemaindasitiri pamusoro petafura yemvura yevhu rakabatana, ivhu rejecha uye nheyo yekurasira marara.
(2) Bored gomba rinowedzera pasi grouting murwi:Chekutanga, shandisa zvakajairwa kubhooresa murwi kuti uteedzere nzira yekuchera yakajairika kudhiraivha mukati meyakagadzirwa dhizaini zvinoenderana nedhayamita yemuviri wemurwi, wobva wabvisa maturusi ekuchera uye kutsiva yakajairwa dhiri neakakosha yekuwedzera yepasi dhiri kusvika pasi. yegomba kuita musoro unowedzera nekuwedzera dhayamita remurwi pasi.
Chekutanga shandisa yakajairika yakabhoweka murwi drill bit kutevedzera yakajairika nzira yekuchera zvinoenderana nedhayamita yemuviri wemurwi kune yakagadzirirwa kutakura layer, wobva wabvisa chishandiso chekuchera, tsiva iyo yakajairwa dhiri nechakakosha pasi-chinowedzera dhiri. pasi pegomba, uye wedzera dhayamita yemurwi pasi kuti uite musoro wekuwedzera.
1. Mamiriro ezvinhu evhu anoshandisika: ivhu rakaoma, repurasitiki rakaomarara riri pamusoro petafura yemvura uye jecha nematombo akaomeswa nematombo ari pamusoro pehutsi hwepakati.
2, Chiyero chekushandisa: zvivakwa zvehurumende uye zvemaindasitiri pamusoro petafura yemvura yevhu rakabatana, ivhu rejecha uye nheyo yekurasira marara.
