Kumukūʻai kūʻai nui no ka mea wehe puka HDD 40 ʻīniha me ke kumu kūʻai hoʻēmi

ʻO ka mea kūʻai nui 40 Inches HDD Horizontal Directional Drilling Hole Opener no Trenchless ma ka waihona mai ka hale hana Kina.
ʻO nā lawelawe Hikina Loa no nā mea kūʻai aku e hana ana i ka ʻeli ʻana i ka pōhaku paʻakikī HDD a me nā kūlana paʻakikī mai ka makahiki 2009, ke hoʻomākaukau maikaʻi nei mākou e hana i kēlā me kēia manawa a me nā wahi āpau.
Kaʻina hana maʻamau no ka mea wehe puka:
KaʻAnuʻu Hana 1: E wili i kahi lua hoʻāʻo
Hāʻawi mākou i nā ʻāpana pailota tricone i hoʻopaʻa ʻia me ka maka metala a me ka elastomer, ʻo nā nui maʻamau e komo pū me 5 1/2", 6", 6 1/2", 7 1/2", 7 7/8", 8 1/2", 9 1/2", 9 7/8", etc.

He loea ka mīkini wehe lua a me ka pailota HDD o Kina Hikina Mamao i ka ʻeli ʻana i nā pōhaku paʻakikī, hiki iā ia ke ʻeli i kekahi ʻano kūlana pōhaku. Inā he pono kikoʻī kāu no ka mea wehe lua, e haʻi mai iā mākou, ke hoʻomākaukau maikaʻi nei mākou e hāʻawi i nā hopena kūpono loa.
Nā kikoʻī
