Imiyoboro yo mu rwego rwohejuru yo kugurisha

Ibisobanuro bigufi:

Imiyoboro yacu isudira ya karubone ibyuma byashizweho kugirango bihangane n’ibidukikije bikaze, byemeza kwizerwa no kuramba. Waba ukeneye imiyoboro yimishinga remezo, gukoresha ingufu cyangwa ubundi buryo bwo gukoresha inganda, ibicuruzwa byacu byashizweho kugirango bitange imikorere isumba iyindi.

Ibicuruzwa

Imiyoboro yacu ikorwa mukuzunguza ibyuma bya karubone nkeya mubyuma bitobora neza, hanyuma bigakurikirwa nuburyo bukomeye bwo gusudira kugirango uburinganire n'ubwuzuzanye burambye. Ubu buryo bushya bwo gukora budufasha gukora imiyoboro minini ya diametre ibyuma bidakomeye gusa ariko kandi bigahinduka, bigatuma biba byiza muburyo butandukanye bwo gukoresha kuva mubwubatsi kugeza gutwara peteroli na gaze.

Uruganda rwacu ruherereye mu mujyi wa Cangzhou, mu Ntara ya Hebei kandi rwabaye umuyobozi mu nganda z’ibyuma kuva rwashingwa mu 1993. Uru ruganda rufite ubuso bwa metero kare 350.000 kandi rukaba rufite ibikoresho bya tekinoloji n’imashini bigezweho, bidushoboza gukora imiyoboro y’icyuma yujuje ubuziranenge yujuje ubuziranenge mpuzamahanga. Hamwe n'umutungo wose wa miliyoni 680 z'amafaranga y'u Rwanda n'abakozi 680 bitanze, twishimiye ko twiyemeje kuba indashyikirwa no guhaza abakiriya.

Umuyoboro ugomba kwihanganira ibizamini bya hydrostatike bitanyuze mu kashe cyangwa umubiri
Ihuriro ntirigomba gupimwa hydrostatike, mugihe ibice byumuyoboro wakoreshejwe mugushira ahabona byageragejwe neza hydrostatike mbere yo guhuza ibikorwa.

Ibyiza byibicuruzwa

1. Kimwe mu byiza byingenzi byimiyoboro yacu isudira ya karubone ibyuma ni ubushobozi bwo gukora imiyoboro minini ya diameter. Ibi bigerwaho binyuze muburyo budasanzwe bwo gukora burimo kuzunguruka ibyuma byoroheje byubatswe mubitereko byerekeranye na tekinike hanyuma bigasudira.

2. Ubu buryo ntabwo bwongera imbaraga nigihe kirekire cyumuyoboro, ahubwo binemerera guhinduka mugushushanya no kubishyira mubikorwa.

3. Imiyoboro yacu irwanya ruswa kandi irashobora kwihanganira umuvuduko mwinshi, bigatuma iba nziza mubikorwa bitandukanye birimo peteroli na gaze, gutanga amazi, nubwubatsi.

Ibura ry'ibicuruzwa

1. Uburyo bwo gukora, nubwo bukora neza, burashobora gutuma habaho itandukaniro ryiza niba ridakurikiranwe neza.

2. Igiciro cyambere cyambere-cyizaumuyoboro w'icyumairashobora kuba hejuru kurwego rwohejuru rwo murwego rwo hejuru, rushobora kuba gutekereza kubikorwa byimishinga.

3.Mu gihe imiyoboro yacu yagenewe kuramba, irashobora gusaba kubungabungwa buri gihe kugirango irebe kuramba, cyane cyane mubidukikije.

Isoko

Amasoko yacu yingenzi akwirakwira mu turere dutandukanye, tukemeza ko dushobora guhaza ibyo abakiriya bacu bakeneye ku isi. Twishimiye kuba twatanze imiyoboro yo mu rwego rwohejuru itujuje ubuziranenge ariko irenze ibipimo nganda. Ubwitange bwacu bwo kugenzura ubuziranenge no guhaza abakiriya byaduhaye izina nkumuntu utanga isoko ryizewe mubyuma.
