Paʻa heleuma
ʻO ka heleuma ʻo ia hoʻi ke koʻokoʻo e hoʻololi i nā hale a i ʻole ka ukana geotechnical i kahi pōhaku paʻa
ʻO ke koʻokoʻo, drill bit, coupling, plate, grouting stopper and nut.Ua hala
hoʻohana nui ʻia i ka tunnling, mining, slope stabilization, tunneldisease treatment and roof supporting
o na hana malalo.No ka lepo maloʻo (palolo, one friable etc.) Hana ʻia ke koʻokoʻo heleuma hollow
paipu ʻole me ka ikaika kiʻekiʻe.
Nā hiʻohiʻona o ka pahu heleuma hollow grounting
• Pono kūpono no nā kūlana lepo paʻakikī.
• Hiki ke hoʻokō ʻia kahi kiʻekiʻe o ka hoʻokomo ʻana mai ka wili ʻana, kau ʻana a me ka grouting i hoʻokahi hana hoʻokahi.
• Hoʻopau ka ʻōnaehana wili iho i ka pono no ka lua pahu pahu.
• Hoʻouka me ka manawa like wili a me ka grouting hiki.
• Hoʻokomo maʻalahi ma nā ʻaoʻao āpau, a i luna hoʻi.
• He kūpono no ka hana ma nā wahi liʻiliʻi, ke kiʻekiʻe a me nā wahi paʻakikī.
• Pūnaehana post grouting maʻalahi.• Hoʻopaʻa wela wela no ka pale ʻana i ka corrosion
Nā noi ma Tunneling & Ground Engineering
• ʻO ka bolting Radial
• Hoʻopaʻa ʻia ka pali
• Forepoling
• Puʻupuʻu micro injection
• Hoʻopaʻa maka
• heleuma kākoʻo no ka manawa
• Hoʻomākaukau puka
• Ke kui lepo
ʻO ka wehewehe ʻana iā Self-Drilling Anchor Bolt
