kusiyana pakati pa kubowola koyima, kuzungulira kwa rotary ndi HDD trenchless

Tanthauzo: Njira yachikhalidwe yobowola yomwe imapanga mabowo olunjika pamwamba pa Dziko Lapansi kuti apeze zinthu zapansi pa nthaka kapena kumanga nyumba zoyima.​

Mfundo Yogwirira Ntchito: Chobowola chozungulira (monga tricone, PDC bit) chimayendetsedwa pansi ndi mphamvu yamakina kapena yamadzimadzi. Madzi obowola (matope) amayendetsedwa kuti aziziritse chobowolacho, kuchotsa zidutswa, ndikukhazikitsa makoma a mabowo.​

Ntchito Zofunika Kwambiri:

• Kutulutsa mafuta, gasi lachilengedwe, kapena mchere (monga malasha, zitsulo).

• Kuboola zitsime zamadzi, zitsime za geothermal, kapena zitsime zowunikira kafukufuku wa zachilengedwe.

Ubwino: Kuzama kwakukulu (mpaka mamita zikwizikwi), kukhazikika bwino, komanso kuyenerera mapangidwe a miyala yolimba.

Zoletsa: Zimafuna malo ambiri pamwamba, zimasokoneza nthaka yapamwamba, ndipo sizingathe kuyenda mopingasa (monga mitsinje, misewu).

2. Kuzungulira

Tanthauzo: Njira yapadera yomangira maziko yomwe imabowola mabowo oyima kapena opendekera pang'ono kuti ike konkire, zitsulo, kapena milu yophatikizika (nyumba zonyamula katundu za nyumba/milatho).​

Mfundo Yogwirira Ntchito: Chobowolera chozungulira chimagwiritsa ntchito chidebe chobowolera kapena chowuzira kuti chikumbe dothi/mwala. Pambuyo popanga dzenje, makhola olimbikitsira amaikidwa, ndipo konkire imathiridwa (nthawi zambiri pansi pa kupanikizika) kuti ipange mulu.​

Ntchito Zofunika Kwambiri:

• Kumanga maziko a nyumba zazitali, milatho, madoko, kapena mafakitale (kuti agawire katundu womangidwa ku zigawo zokhazikika za pansi pa nthaka).

• Kukhazikitsa malo otsetsereka kapena kukonza maziko omwe alipo kale.

Ubwino: Kupangika kwa milu mwachangu, kumasintha nthaka zosiyanasiyana (dongo, mchenga, miyala yofewa), ndipo kumachepetsa kugwedezeka poyerekeza ndi kuyika nyundo.​

Zoletsa: Zimafunika kukonzekera malo osalala, zingayambitse kugwa kwa zitsime m'nthaka yotayirira (yomwe imafunika chidebe), ndipo zimangofunika kuya kosaya kwambiri mpaka pakati (nthawi zambiri pansi pa mamita 100).​

3. HDD Trenchless (Kuboola Molunjika Molunjika)​

Tanthauzo: Njira yatsopano "yosakumba" yomwe imabowola mabowo opingasa kapena olunjika pansi pa nthaka kuti ikhazikitse zinthu zogwiritsa ntchito pansi pa nthaka (mapaipi, zingwe) popanda kukumba ngalande.​

Mfundo Yogwirira Ntchito:

1. "Dzenje laling'ono" limabowoledwa m'njira yopingasa yokonzedwa kale pogwiritsa ntchito mutu wobowolera wowongoka (wotsogozedwa ndi GPS kapena gyroscopes).

2. Bowo loyendetsera ntchito limakulitsidwa (kukonzedwanso) kuti lifanane ndi kukula kwa utility diameter.

3. Chitoliro/chingwe chamagetsi chimakokedwa kudzera m'chitsime chokulirapo.

Ntchito Zofunika Kwambiri:

• Kuyika mapaipi amadzi/zimbudzi, magasi, kapena zingwe za fiber-optic pansi pa misewu, njanji, mitsinje, mabwalo a ndege, kapena madera omwe ali ndi vuto la chilengedwe (monga madambo).​

Ubwino: Kuchepetsa kusokonezeka kwa pamwamba (palibe kukumba ngalande), kumasunga zomangamanga/kuyenda kwa magalimoto, komanso kuchepetsa kuwonongeka kwa chilengedwe.

Zoletsa: Kuzama kochepa (nthawi zambiri pansi pa mamita 100), kumangokhala dothi lofewa mpaka lapakati (miyala yolimba imawonjezera mtengo), ndipo imafuna kuyenda molondola (chiopsezo cha kupatuka kwa njira yobowolera).​
