Matembenuzidwe a chigawo chimodzi
1. Chigawocho chimakhala chopunduka panthawi yoyendetsa, zomwe zimapangitsa kuti afe kapena kupindika mofatsa, zomwe zimapangitsa kuti chigawocho chitha kukhazikitsidwa.
Kusanthula zomwe zimayambitsa:
a) Mapindikidwe omwe amapangidwa akapangidwa zigawozo, nthawi zambiri amawonetsedwa ngati kupindika pang'onopang'ono.
b) Pamene chigawocho ndi kunyamulidwa, mfundo thandizo si wololera, monga chapamwamba ndi m'munsi khushoni khushoni si ofukula, kapena stacking malo subsidence, kotero kuti membala adzakhala ndi kupindika akufa kapena mapindikidwe pang'onopang'ono.
c) Zigawo zimakhala zopunduka chifukwa cha kugundana panthawi yamayendedwe, nthawi zambiri kumawonetsa kupindika.
Njira zopewera:
a) Pakupanga zigawo zikuluzikulu, njira zochepetsera ma deformation ziyenera kutengedwa.
b) Pamsonkhano, miyeso monga reverse deformation iyenera kutengedwa.Ndondomeko ya msonkhano iyenera kutsata ndondomekoyi, ndipo zothandizira zokwanira ziyenera kukhazikitsidwa kuti zisawonongeke.
c) Poyendetsa ndi zoyendetsa, samalani ndi kasinthidwe koyenera ka ma pads.
Zothetsera:
a) Kupindika kwa membala wakufa nthawi zambiri kumathandizidwa ndi kukonza makina.Gwiritsani ntchito ma jacks kapena zida zina kukonza kapena ndi lawi la oxygen acetylene mutatha kukonza.
b) Pamene kapangidwe ndi mokoma kupinda mapindikidwe, kutenga oxyacetylene lawi Kutentha kukonza.
2. Pambuyo posonkhanitsa mamembala azitsulo zachitsulo, kupotoza kwautali wonse kumaposa mtengo wololeka, zomwe zimapangitsa kuti pakhale kusamalidwa bwino kwachitsulo chachitsulo.
Kusanthula zomwe zimayambitsa:
a) Njira yosoka ndiyopanda nzeru.
b) Kukula kwa ma node osonkhanitsidwa sikukwaniritsa zofunikira zapangidwe.
Zothetsera:
a) Zigawo za Msonkhano kuti zikhazikitse tebulo la msonkhano, monga kuwotcherera pansi pamiyeso ya membala, kuti muteteze kuphulika.Kusonkhanitsa tebulo ayenera aliyense fulcrum mlingo, kuwotcherera kupewa mapindikidwe.Makamaka pa msonkhano wa mtengo kapena makwerero, m'pofunika kusintha mapindikidwe pambuyo udindo kuwotcherera, ndi kulabadira kukula kwa mfundo kuti agwirizane ndi kamangidwe, apo ayi n'zosavuta chifukwa kupotoza chigawo chimodzi.
b) Membala wosakhazikika bwino alimbikitse membala asanatembenuke ndi kuwotcherera, ndipo membalayo ayeneranso kusanjidwa pambuyo potembenuzira, apo ayi membalayo sangawongoleredwe atawotcherera.
3. Components arch, mtengo wowuma waukulu kapena wocheperapo kuposa mtengo wapangidwe.Pamene mtengo wa arch wa chigawocho ndi chaching'ono, mtengowo umaweramitsidwa pambuyo pa kukhazikitsa;Pamene mtengo wa arch ndi waukulu, kukwera pamwamba pa extrusion ndikosavuta kupitirira muyezo.
Kusanthula zomwe zimayambitsa:
a) Kukula kwa chigawocho sikukwaniritsa zofunikira zamapangidwe.
b) Pomanga, miyeso yoyezera ndi yowerengeka sikugwiritsidwa ntchito
