Nangula Wowonjezera wa Hydraulic
Water Swelling Friction Bolt imapangidwa ndi chubu champhamvu kwambiri chopindika chodzipindika chokha ndikumangirira kuti chisindikize kumapeto konse kwa bawuti.
Mfundo yogwirira ntchito:
Bolt ikagwiritsidwa ntchito mu dzenje, chitsamba chokhala ndi dzenje chimalumikizidwa ndi chuck ya pampu yamadzi yothamanga kwambiri.Yambani mpope ndikulowetsa madzi mu chubu, khoma lopindika la bawuti limakakamizika kukulitsa.Pampu ikafika pazitsulo zokhazikika, khoma la bolt limagwira pa strata ndipo limapanga mphamvu yotsutsana kwambiri yothandizira.Choncho, chitetezo ndi dongosolo lokhazikika lothandizira limapangidwa.
Kugwiritsa ntchito kwakukulu kwa Hydraulic Expansion Anchor ndikulimbitsa kwakanthawi kwa miyala mu Mining ndi Tunneling.Mphamvu zomangirira pakati pa friction bolt ndi rock mass zimayamba chifukwa cha kutsekedwa kwa mawonekedwe ndi kusamutsidwa kwamphamvu pakati pa khoma la borehole ndi thanthwe lomwe limakulitsidwa ndi kuthamanga kwa hydraulic.
Minda Yogwiritsira Ntchito:
Kulimbitsa mwadongosolo zofukula pansi
Kuwongolera kwakanthawi kochepa
Ubwino waukulu:
Mphamvu yonyamula katundu nthawi yomweyo pamtunda wonse woyikidwa
Kutsika kwamphamvu motsutsana ndi kugwedezeka komwe kumachitika chifukwa cha ntchito zophulika
Kutha kusunga mphamvu yonyamula katundu ngakhale mutakhala ndi ma deformation
Kukhazikitsa kotetezeka komanso kosavuta
Palibe zowonjezera zomangira zomwe zimafunikira pakuyika
Kusinthasintha ngati kusiyanasiyana kapena kusiyanasiyana kwa borehole
fufuzani khalidwe pa aliyense unsembe umodzi
