Hoʻohana ākea ʻo SWMC 370-DTH subsurface drig rig i nā kahua kūkulu

Ua hoʻopau kūleʻa ʻo SWMC 370 subsurface drig rig i ka papahana grouting kahua o kahi papahana waiwai ma Guangzhou, Kina.

Kuhi ʻia kahi papahana waiwai ma Guangzhou i kahi o 62,000 m2, a nona ka 44,000 m2 ma uka a me 18,000 m2 i lalo o ka honua. Aia he 25 mau papahele ma luna o ka honua, me nā papahele he 4 ma lalo o ka pahu a he 4 mau papa ma lalo o ka honua. ʻO 108.8m ka nui o ke kiʻekiʻe o ka hale, ʻo 16.9m ka hohonu o ka lua o ke kahua, a ʻo 21.1m ka wahi o ka wahi.

Ke noʻonoʻo nei i ka hopena anti-lana o ka papahele o lalo, ua hoʻonohonoho ʻia ka pūʻulu anti-lana i ka podium hema o kēia papahana. ʻO ke anawaena o ka hoʻopaʻa anti-lana i 130mm, ʻo ka spacing ka 780mm, a ʻo ka hohonu o ka lua he 8m.

He mana koʻikoʻi ka koho ʻana o nā mīkini ʻeli i ka holomua o ka papahana anti-lana i hoʻokumu ʻia. Ua koho ʻo SWMC i kahi mīkini ʻeli lalo SWMC 370 no ka ʻoihana kūkulu, kahi i kūlike i ʻelua mau set o ka compressor air SullAIR American 600RH, me ka hana hana o 1.7 Mpa a me ka neʻe ʻana o ka ea o 17m3. Loaʻa iā ia kahi hana kūpono kiʻekiʻe, hoʻemi i ka ikehu haʻahaʻa, hoʻolālā mechanical maʻalahi, hana maʻalahi a me ka kaohi, hiki ke hoʻololi i ka kaohi o nā ʻeliʻeli i ka manawa maoli, a me kāna hana a me kāna hana e hiki ai ke hoʻokō i nā pono o ka papahana.

ʻO SWMC 370 subsurface drilling machine kahi mīkini ʻeli hoʻomohala honua kiʻekiʻe, e hāʻawi ana i ka pono kiʻekiʻe, pono kiʻekiʻe a me nā mīkini ʻeli he nui no ka hoʻokumu ʻana i ka ʻenekini grouting. Ma kēia papahana, ʻo ka noi o SWMC 370 subsurface drilling machine, hoʻomaikaʻi maikaʻi i ka pono kūkulu.

Ma muli o ka pōhaku i haki maoli ʻia, ma mua o ka haki ʻana o ka pōhaku, hui pū ʻia me ka wikiwiki o ka hoʻokuʻu slag kiʻekiʻe, lalo o ka puka maemae, ʻaʻohe hanana haki hou, no laila ʻo SWMC 370 mīkini hoʻoheheʻe hydraulic, he ʻoi aku ka maikaʻi o ka ʻeli a me ka hoʻohana ʻana o ka ikehu ma mua o ka rotary maʻamau ʻeli ʻana.

Hiki i ka SWMC 370 drig rig ke hoʻopau i kahi lua o ka ʻeli ʻana, ma muli o ka hopena DTH hydraulic o ka lua o ka lua, pōkole loa ka manawa pōhaku percussive, loli ʻole ka lithology paʻakikī paʻakikī i ka hopena o ka haki ʻana ʻaʻole maʻalahi, ʻaʻole maʻalahi e hana i ka ʻenekini deflection ma kahi liʻiliʻi. , no laila ke hoʻokumu nei i nā lula o ka lua, maikaʻi maikaʻi, maʻemaʻe, a hiki ke pale pono i ka pōhaku paʻakikī a me ka hoʻokumu ʻana i ka lua o ka pilikia. Ma muli o ka wikiwiki o ka wikiwiki o ka hana ʻeli ʻana, ʻo ka manawa o ka hoʻokuʻi ma waena o nā mea ʻeli a me ka paia o ka puka hoʻemi ʻia, no laila ʻaʻole maʻalahi ka hāʻule o ka paia hole a me nā pōʻino ʻē aʻe.

Ua mahalo ʻia ʻo SWMC 370 subsurface mīkini ʻeli e ka ʻaoʻao kūkulu ma kēia papahana no ka mea o nā mea maikaʻi e like me ka pilina maʻalahi, ke kūkulu kūpono, ka pilikia maopopo a me ka wā pōkole kūkulu. I kēia manawa Hoʻohana nui ʻia ia i ke kūkulu ʻana i nā papahana kūkulu.
