Ua hoʻopau maikaʻi ʻo SWMC 370 subsurface drilling rig i ka papahana grouting kumu o kahi papahana waiwai ma Guangzhou, Kina.

ʻO kahi papahana waiwai ma Guangzhou e uhi ana i kahi o 62,000 m2, nona ka 44,000 m2 ma luna o ka honua a ʻo 18,000 m2 ma lalo o ka lepo.He 25 papa ma luna o ka honua, me 4 papa ma lalo o ka podium a me 4 papa ma lalo o ka honua.ʻO ka nui o ke kiʻekiʻe o ka hale ʻo 108.8m, ʻo ka hohonu o ka lua kumu he 16.9m, a ʻo ka wahi kūloko he 21.1m. Ua hoʻolālā ʻia ka ʻenehana ʻenekinia e like me ka hoʻoikaika ʻia ʻana o ka paʻa paʻa paʻa i ka paia a ua hoʻolālā ʻia ke kumu e like me ke kumu palahalaha.

Ke noʻonoʻo nei i ka hopena anti-floating o ka papahele haʻahaʻa, ua hoʻonohonoho ʻia ka hui bolt anti-floating ma ka podium hema o kēia papahana.He 130mm ka anawaena o ka bolt anti-floating, he 780mm ka spacing, a he 8m ka hohonu o ka lua.

ʻO ke koho ʻana i nā mīkini wili he mana koʻikoʻi i ka holomua maʻalahi o ke kahua anti-floating bolt project.SWMC i koho ʻia ʻo SWMC 370 subsurface drilling machine no ka ʻoihana kūkulu, e pili ana i ʻelua pūʻulu o SULLAIR American 600RH air compressor, me ke kaomi hana o 1.7 Mpa a me ka neʻe ʻana o ka ea o 17m³.Loaʻa iā ia ka hana hana kiʻekiʻe, ka haʻahaʻa haʻahaʻa o ka ikehu, ka hana mechanical maʻalahi, ka hana maʻalahi a me ka mana, hiki ke hoʻololi i ka mana o nā ʻāpana wili i ka manawa maoli, a hiki i kāna hana a me ka pono ke hoʻokō i nā pono o ka papahana.

SWMC 370 subsurface drilling machine he kiʻekiʻe kiʻekiʻe ka hana hoʻoheheʻe ʻana i lalo, e hāʻawi ana i ka hana kiʻekiʻe, hilinaʻi kiʻekiʻe a me nā mīkini hoʻoheheʻe multi-functional no ke kahua grouting engineering.

Ma muli o ka haʻihaʻi nui ʻana o ka pōhaku, ma mua o ka wili ʻana i haki, hui pū ʻia me ka wikiwiki o ka hoʻokuʻu ʻana o ka slag, lalo o ka lua maʻemaʻe, ʻaʻohe mea ʻoki pinepine ʻia, no laila ʻo SWMC 370 hydraulic drilling machine, ʻoi aku ka kiʻekiʻe o ka wili ʻana a me ka hoʻohana ʻana i ka ikehu ma mua o ka rotary maʻamau. wili ʻana.

Hiki iā SWMC 370 drilling rig ke hoʻopau i nā lua wili maikaʻi, ma muli o ka hopena hydraulic DTH o lalo o ka lua, pōkole loa ka manawa percussive rock, ʻaʻole nui ka hopena o ka lithology pōhaku paʻakikī, ʻaʻole maʻalahi ke hana i kahi torque deflection ma ka bit. , pela ka hana ana i na rula o ka puka, maikai maikai, maemae, a hiki pono ke pale aku i ka pohaku paakiki a me ka paʻakikī o ka hoʻoheheʻe ʻana i ka lua inclination o ka pilikia. hoʻemi ʻia, no laila ʻaʻole maʻalahi ka hāʻule ʻana o ka pā puka a me nā pōʻino ʻē aʻe.

Ua mahalo ʻia ʻo SWMC 370 subsurface drilling machine e ka hui kūkulu ʻana i kēia papahana ma muli o kona mau pono e like me ka pilina maʻalahi, ka hana maʻalahi, ke koʻikoʻi maʻemaʻe a me ka wā kūkulu pōkole.I kēia manawa, hoʻohana nui ʻia i nā hana kūkulu hale.
