Nānā nui o ka Pipe Steel Grouting no Bridge Pile Foundation
ʻO ka paipu kila Grouting he mea hoʻohana nui ʻia i nā mea hana e like me ka hoʻolālā, tunnels, a me ka ʻenekinia lalo.ʻO kāna hana nui ka hoʻokomo ʻana i nā mea grouting i loko o nā lua lalo, hoʻopiha i nā āpau, a hoʻomaikaʻi i ka hiki ke hāpai a me ke kūpaʻa o ke kumu.Loaʻa i nā paipu grouting nā mea maikaʻi o ka hana maʻalahi, hana maʻalahi, a me nā hopena koʻikoʻi, no laila ua hoʻohana nui ʻia lākou i ka ʻenekinia lalo.
ʻO ka wehewehe ʻana o ka Pipe Steel Grouting no ka Bridge Pile Foundation

Hoʻohana i nā paipu kila grouting
ʻO ka paipu hao hao he mea hoʻohana maʻamau i ka pipeline, hoʻohana nui ʻia i nā ʻoihana, mālama wai, kūkulu, pale ahi, a me nā māla ʻē aʻe.Loaʻa iā ia ke kūpaʻa corrosion maikaʻi a me ke kūpaʻa ʻana, a loaʻa kekahi ikaika compressive.
ʻO nā paipu hoʻoheheʻe kila i hana mau ʻia me ke kila kila a no laila ke kūpaʻa maikaʻi ka corrosion.Eia kekahi, ʻo ke kila grouting paipu kekahi i kekahi ikaika compressive a hiki ke kū i kahi nui o ke kaomi.Eia kekahi, ʻo ke kila grouting paipu hoʻi he pale pale a hiki ke hoʻohana ʻia no ka manawa lōʻihi.
