Pali zovuta zina zomwe zimachitika nthawi zina pobowola mozungulira.Mavuto omwe amapezeka pamapulojekiti obowola mozungulira ndi mayankho ndi awa:
1.Piling chida chopanikizana
Zifukwa zomwe zikuchitika:
1) Mumchenga wosanjikiza dzira ndi mchenga wosanjikiza, khoma la dzenje limachitika mosavuta malo akulu ophwanyika ndikupangitsa kuti chida chochulukira chodzaza.2) Pakapita nthawi kulowa mozama kwambiri mu dongo, chibowo chobowoleredwa ndi chida chodzaza.
Zothetsera:
1) Njira yokwezera, mwachitsanzo, kuikweza ndi crane kapena makina onyamula ma hydraulic.
2) Njira yotsekera, mwachitsanzo, yeretsani zisenga kuzungulira chubu chobowola pobweza kapena kudula pansi pamadzi, kenako kwezani.
3) Kukumba njira, mwachitsanzo, ngati malo a jamming si ozama, kukumba ndi kuyeretsa dregs.
2.Chingwe chachikulu cha windlass chimaduka
Chingwe chachikulu cha waya wa windlass ndikuswa mosavuta ngati kuli kosayeneraogwira ntchito.Ndiye mphepo yamkuntho ikugwedezekachingwe ndi kumasula chingwe sayeneraZachiwawa kapena zotayirira kwambiri.Ngati wayachingwe ndi flokkated, ayenera m'malom'kupita kwa nthawi, kupewa kusweka ndi kuyambitsa
kugwa pansi.
3.Kuvala ndi kutayikira kwa mutu wa mphamvu mkati mwa chitsamba
Kupatula kuwonongeka kwa kapangidwe, izi ndichifukwa cha kubowolakuthekera kwakukulu kopanga.Choncho ayenera kulabadiraluso lopanga makina,musagwire ntchito mochulukira.
4.Hole kugwa
Zimayamba chifukwa chosagwiritsa ntchito bentonite kapena kugwiritsa ntchito bentonite yochepa pobowola.Pofuna kupewa kugwa kwa dzenje pobowola, kuyenera kusunga mlingo wa madzi mu dzenje pamwamba pa mlingo wa madzi apansi panthaka, ndikuwongolera kuthamanga ndi kutsika.
5.Kutulutsa bentonite
Zimagwirizana ndi msinkhu wa madzi apansi panthaka komanso ntchito ya bentonite.Ngati dera lalikulu la bentonite likutuluka, liyenera kudzazidwa.Ngati kutayikira si kwambiri, ndiye kusintha ntchito bentonite.Ikhoza kuyika konkire mu bentonite, kusakaniza ndikugwiritsa ntchito.
6.Kubowola kuya sikuchulukira

Miyezo: Ngati itsetsereka, sinthani mano ndi ngodya ya 60 °, mutha kuyithetsa poponya mwala mudzenje, kusintha ndi mutu wobowola kapena chobowola.
7.Kuthira nthaka movuta
Nthawi zina matope omwe ali mkati mwa bowolo amakhala ovuta kutulutsa chifukwa matopewo amakhala omata kwambiri.Itha kuthetsedwa powotcherera mabowo pamutu wobowola.
