ʻO ka wili heleuma hydraulicHe mīkini hopena pneumatic, ka mea i hoʻohana nui ʻia no ka heleuma pōhaku a me ka lepo, subgrade, slope treatment, underground deep foundation pit support, tunnel a puni ka pōhaku paʻa, landslide prevention and other poʻomanaʻo, underground engineering support and high-rise building foundation treatment. He kūpono ia no ka hoʻomalu ʻana i ka lua hoʻopaʻa hohonu a me ka lepo slope nailing Engineering non prestressed heleuma kākoʻo.
Hoʻohana pinepine ʻia nā ʻano ʻelua no ka hana ʻana i ka paia nailing lepo:
a. Hoʻokumu ʻia ka pahu heleuma mortar ma ka wili ʻana, hoʻokomo i ka hoʻoikaika a me ka grouting. ʻO kēia ʻano hana ka manawa a me nā mea waiwai, a ʻaʻole maʻalahi ke kūkulu ʻana i ka papa one convective a me ka ʻiliʻili;
b. ʻO ia ka hana ʻana i ka hoʻoikaika ʻana i ke kaula, ke kila kihi, ka paipu kila a me nā mea ʻē aʻe i loko o ka mīkini kui lepo, a i ʻole e hoʻokuʻu lima iā lākou i loko o ka papa lepo a i ʻole ka ʻiliʻili e hana i ka paia nailing lepo.
ʻO karig wili heleuma hydraulicua haku ʻia me ka ʻenekini nui, ka pahu hau, ka mea hoʻopā, ke poʻo hāmare, ka ʻoluʻolu, ka ʻauwaʻa ea, a me nā mea ʻē aʻe.
Ma mua o ka hoʻokomo ʻana i ka rig wili heleuma, e ʻike pono ʻia ke kūlana puka a me ka hoʻonohonoho ʻana i ka puka heleuma e ka theodolite a kaha ʻia. ʻO ka hewa ākea o ke koʻokoʻo heleuma ʻoi aku ka liʻiliʻi ma mua o 50mm a ʻo ka hewa kū i lalo o 100mm.
