ʻo ke kila piha piha i ka ʻeli ʻana i ka pōhaku ʻo ka pahu heleuma / nā lāʻau heleuma

Hoʻokumu ʻia ka ʻōnaehana Self Drilling Anchor me kahi pahu heleuma hollow threaded me kahi drill bit e hana ana i ka wili, heleuma a me ka grouting i ka hana hoʻokahi.Hoʻohana nui ʻia ka ʻōnaehana heleuma hoʻoheheʻe pilikino i ka slope stabilization, tunneling pre-support, nā kumu me nā micro piles etc.

ʻO nā pono a me nā hiʻohiʻona e like me lalo:

1. ʻAʻole koi ʻia nā pahu, no ka mea, hiki ke wili ʻia nā lāʻau heleuma i loko o nā lepo maloʻo me ka ʻole o nā pahu e kākoʻo i nā lua.

2. ʻO ka hoʻokēʻai wikiwiki a me ka hoʻokomoʻana, no ka mea,ʻo ka hoʻouluʻana, ka hoʻokomoʻana a me ka grouting i loko o ka hana hoʻokahi.

3. ʻO nā kaula kaula ʻelua a me nā kaula trapezoid he paʻa a kūpono hoʻi no ka wili ʻana i ka rotary-percussive a me ka hoʻopaʻa ʻana i kahi kiʻekiʻe o ka pilina me ka luawai gout.

4. ʻAʻole hoʻohana wale ka hollow core no ka flushing i ka wā wili, akā no ka grouting ma hope o ka wili ʻana.

5. ʻO nā lola hoʻomau e hōʻoia i ka hiki ke ʻoki ʻia a hoʻohui ʻia i kēlā me kēia wahi, a i ʻole e hoʻonui ʻia.

6. Loaʻa nā ʻāpana heleuma like ʻole no nā kūlana honua like ʻole.

R pae heleuma pae a i 'ole i kapa 'ia pōhaku bolt, lepo kui, 'o ia ke 'ano o ka threaded hollow bar, bar surface me ke kaula kaula e like me ISO 10208 & 1720. Ua hana mua ia e MAI ma 1960S e hoʻoponopono i ka haʻahaʻa hana wikiwiki ma ka paʻakikī. nā hana ma lalo o ka honua, i kēia mau lā;kaulana loa ia a puni ka honua.
