Kuphatikizika kwa zingwe zopangira chitofu chowotcha, kuyambira pansi pang’anjo kupita kunjira yopangira ng’anjo yapamwamba ~
Mapulani omanga a chitofu chonse cha ng’anjo yoyaka moto amagawidwa ndi opanga njerwa zokanira.
1. Kumanga grouting pansi pa chitofu choyaka moto:
Pansi pa chitofu chowotchacho chatenthedwa ndi miyala, matope osakanizidwa ayenera kugwiritsidwa ntchito kudzaza kusiyana pakati pa miyalayo kuti iwonjezere kusindikiza kwake ndi mphamvu.
Njira ya grouting ndi:
(1) Gwiritsani ntchito pampu yothamanga kwambiri kukanikiza mumatope oponderezedwa, siyani kugwetsa pamene doko lina la gitala latuluka kapena mutu wa chitoliro cha mphira chaphulika, ndikuyamba kumera pa doko lotsatira.
(2) Grouting yonse ikasiya kukakamiza, gwiritsani ntchito pulagi yamatabwa kapena kutsekeka kwa chitoliro kuti mutseke potsegulira. Pambuyo pa mipope yonse ya grouting yodzaza ndi grouting ndipo slurry ya refractory imakhazikika, chotsani chitoliro cha grouting, ndiyeno gwiritsani ntchito mbale yachitsulo kuti musindikize ndi kuwotcherera poyambira.
2. Kupanga koponyera pansi pa chitofu choyaka moto:
(1) Gawo la zoponyedwa, kuchuluka kwa madzi owonjezera, ndi kusakaniza ndi kumanga ziyenera kuchitidwa mosamalitsa motsatira malangizo a fakitale kwa oponyedwa.
(2) Panthawi yothira, kukwera pamwamba ndi flatness ya castable ayenera kufufuzidwa nthawi iliyonse. Iyenera kuwongoleredwa ndi mzere wokwezeka womwe walembedwa pagawo la kabati ndi chipolopolo cha ng’anjo, ndipo chipinda choyaka moto chiyenera kuyendetsedwa ndi zitsulo zowotcherera.
3. Mzere wa chitofu choyaka moto:
Gwiritsani ntchito njira yochotseramo kuti mutulutse mzere wapakati wa mtanda pakati pa kabati ndi chipinda choyaka moto, ndikuyika arc ya khoma ndi chingwe chothandizira cha khoma lachipinda choyaka ndi arc board.
(1) Kumanga khoma la ng’anjo:
1) Ikani ulusi wa ceramic womwe umamveka pafupi ndi pamwamba pa ❖ kuyanika kwa ng’anjo yamoto, ndipo ulusi umamveka uyenera kukhala woyandikana, ndipo makulidwe ake ayenera kukwaniritsa mapangidwe ndi zomangamanga.
2) Pambuyo pomanga ulusi wa ceramic utatha, yambani kumanga njerwa zotchingira zopepuka zopepuka, ndipo pomaliza mumange njerwa zolemetsa zolemetsa zogwirira ntchito.
3) Mangani khoma la chipinda choyatsira moto choyamba, kenaka pangani khoma la regenerator, ndipo potsirizira pake pangani njerwa zomangira, ndikubwereza kumanganso kumtunda komweko.
(2) Kumanga njerwa zophatikizika:
1) Choyamba, tulutsani m’munsi mwa njerwa yopangidwa ndi mphete yakunja ndikuyika chizindikiro pa chipolopolo cha ng’anjo, ndikuyika ndodo yapakati pa dzenje kuti muwongolere malo ozungulira.
2) Mangani njerwa zophatikizika ndi theka loyamba, kuyambira mphete yakunja mpaka mphete yamkati. Mukamaliza kumanga matabwa ozungulira, ikani matayala ozungulira ndikuyamba kumanga njerwa zam’mwamba zozungulira.
(3) Zomangira njerwa za Checkered:
1) Yang’anani kukwera kopingasa, kusalala ndi dzenje la gridi ya kabati, ndi zina zotero, zonse ziyenera kukwaniritsa kapangidwe kake ndi zomangamanga.
2) Pambuyo potsimikizira kuti kabatiyo ndi woyenerera, tulutsani mzere wautali wa njerwa pakhoma lalikulu ndikulemba mzere wa gululi.
3) Pambuyo poyang’ana njerwa pa chipinda choyamba, yang’anani ndikusintha tebulo la njerwa ndi malo a gridi.
4) Kukula kwa mgwirizano wokulirapo pakati pa njerwa yoyang’anira ndi khoma kuyenera kukhala 20-25mm, ndikukhala mphero yolimba ndi mphero yamatabwa.
5) Malinga ndi zofunikira za kamangidwe kagawo lachiwiri ndi lachitatu la njerwa zomangira, mizere ya gridi yamiyala imayikidwanso pakhoma. Zomangamanga ndi makonzedwe a chigawo chachinayi ndi zofanana ndi zoyamba, ndipo kukula kwapang’onopang’ono kwapamwamba ndi kumunsi kumaloledwa. Kupatuka sikuyenera kupitirira 3mm.
(4) Kumanga kwa chipinda chosungiramo chitofu chowotcha:
1) Dziwani kutalika kwa mzere wa njerwa zomangira zomangira za gawo loyamba la gawo la cylindrical malinga ndi kukwera kwapansi pa njerwa ya catenary arch phazi limodzi. Tsimikizirani kuti ndi woyenera.
2) Pamwamba pazitsulo zamatabwa pa mphete ya pallet iyenera kukonzedwa ndi kuponyedwa kwamphamvu kwambiri.
3) Dziwani malo a malo olamulira a gawo la cylindrical malinga ndi pakati pa dzenje lapamwamba.
4) Pambuyo pa chipinda choyaka moto ndi njerwa zowunikira zimamangidwa ndipo khalidweli likutsimikiziridwa kuti ndiloyenera, yambani kukhazikitsa mbale yapakati.
Gwiritsani ntchito mphira kuti muphimbe chowonjezera chonse, kenaka chotsani mbale yoyaka moto yopachikika, ndipo gwiritsani ntchito chotchinga chotetezera kuti muphimbe chipinda choyaka moto. Ikani shaft yapakati yozungulira, ikonzereni mmwamba ndi pansi pakatikati pa dzenje lakumwamba ndi pa rabara, ikani template ya radian, ndikulemba mzere wa kutalika kwa njerwa pa bolodi.
5) Pamene kutalika kwamiyala kwa gawo la chipindacho kumakwera, kutalika kwa scaffold erection kumakwezedwa molumikizana.
6) Pomanga gawo la chipinda chotchinga, kutsetsereka kwapansi kuyenera kuyang’aniridwa nthawi iliyonse, ndipo cholakwika chovomerezeka chowongolera chiyenera kusinthidwa kuti chikhale chochepera 1mm panthawi.
(5) Mukamaliza kumanga gawo la cylindrical la chipinda chotchinga, yambani kumanga njerwa zolumikizana. Zomangira njerwa zophatikizana ziyenera kuchitika kuchokera pansi mpaka pamwamba. Njerwa zophatikizika zimayalidwa kaye ndiyeno njerwa zolowa pamodzi zimayalidwa.
1) Pomanga njerwa zolowa m’munsi, njerwa zolumikizira ziyenera kuyikidwa poyamba, ndipo zolumikizira ziyenera kusungidwa molingana ndi zofunikira pakumanga, ndipo mfundozo ziyenera kudzazidwa ndi mfundo zokulirapo ndikukhazikika ndi mawaya achitsulo. .
2) Kumanga pamwamba pa njerwa zophatikizika zolumikizira ziyenera kuyang’aniridwa nthawi iliyonse chifukwa cha kukwera kwake, kusalala komanso utali wozungulira wamiyala, ndipo sipayenera kukhala chodabwitsa, ndipo kusintha kwa arc kuyenera kukhala kosalala.
3) Kumanga kwa njerwa zolumikizira kumalizidwa, yambani kumanga njerwa zolumikizira. Popeza njerwa yophatikizikayi sigwiritsa ntchito matope omangira miyala, timizere tating’ono tamatabwa timayenera kugwiritsidwa ntchito kuikonza musanamange.
4) Mukayala cholumikizira chapamwamba, njira yomanga ndi yofanana, koma palibe chifukwa chosungira zolumikizira zowonjezera.
(6) Chipinda chapamwamba chikayikidwa pamtunda wa pafupifupi 1.5 ~ 2.0m kuchokera pa dzenje la chipwirikiti, yambani kuyika matayala okhotakhota kuti amange malo opindika pamwamba.
Pamene kutalika kwa miyala yamtengo wapatali ya arc ikukwera, kupendekerako kumakula pang’onopang’ono. Panthawi imeneyi, makadi mbedza ayenera kugwiritsidwa ntchito kuonjezera bata wa zomangamanga refractory njerwa.
