中文Njira yomangira yozungulira komanso yodzaza ndi makoma imatchedwa njira ya SUPERTOP ku Japan. Casing yachitsulo imagwiritsidwa ntchito kuteteza khoma panthawi yopanga dzenje. Ili ndi mawonekedwe amtundu wabwino wa mulu, osaipitsa matope, mphete yobiriwira, komanso kutsika kokwanira kodzaza konkire. Itha kuthetsa bwino mavuto akugwa kwa dzenje, kutsika kwa khosi, ndi kudzaza kwakukulu komwe kumachitika pamene njira wamba zimagwiritsidwa ntchito pomanga milu yoponyedwa m'matauni odzaza ndi ma karst landforms.
Kubowola miyala
Kubowola kozungulira konse kumakhala ndi torque yamphamvu, mphamvu yolowera ndi mutu wodula, womwe umatha kumaliza ntchito zomanga mumipangidwe yamiyala yolimba. Kulimba kwa thanthwe komwe kungabowole kumatha kufika: uniaxial compressive mphamvu 150-200MPa; chifukwa cha ntchito yake yodula bwino, yakhala ikugwiritsidwa ntchito kwambiri podula: midadada ya konkire, ma bolts amphamvu kwambiri, milu ya H, milu yazitsulo zachitsulo ndi zomangamanga zina zoyeretsa.
Kumanga milu yoponyera m'malo kudzera m'mapanga
Zipangizo zobowola mozungulira bwino zili ndi zabwino zosayerekezeka pomanga phanga kuposa njira zina zomangira: safuna kubweza miyala kapena kusungitsa kowonjezera. Ndi ntchito yakeyake yabwino yosinthira mowongoka, kuwongolera kwachangu pakubowola liwiro, kuthamanga kwa kubowola, ndi torque, imatha kumaliza ntchito yobowola mosavuta kuphanga. Mukathira konkire m'phanga, zimachitika mu casing, ndipo konkire ndi kuwonjezera kwa wothandizira mwamsanga sikophweka kutaya. Ndipo chifukwa chobowoleracho chimakhala ndi mphamvu yokoka kwambiri, chimathanso kuchedwetsa kukoka. Chifukwa chake, imatha kumaliza ntchito yomanga milu yoponyedwa m'phanga.
Kulondola kwapamwamba kwambiri
Ikhoza kukwaniritsa kulondola kwa 1/500 (zobowola zozungulira zimatha kufika 1/100), yomwe ndi imodzi mwa njira zopangira maziko omwe ali olondola kwambiri padziko lonse lapansi.
1. Kusintha kwa makina opangira milu yozungulira mozungulira
Zida zazikulu ndi zigawo zake:
1. Kubowola mozungulira mozungulira: kupanga dzenje
2. Chophimba chachitsulo: chitetezo cha khoma
3. Malo opangira magetsi: amapereka mphamvu kwa injini yaikulu yozungulira
4. Foloko yochitira: imapereka mphamvu yochitira kuti injini yayikulu isasunthike panthawi yozungulira mozungulira
5. Chipinda chogwirira ntchito: nsanja yogwirira ntchito, malo ogwira ntchito
Zida zothandizira:
1. Kubowola mozungulira kapena kugwira: kuchotsa nthaka, kulowa miyala, kuyeretsa dzenje
2. Makina ojambulira chitoliro: kutulutsa chitoliro, kuzungulira kwathunthu kuti apange ntchito yoyenda
3. Crawler Crane: kukweza makina akuluakulu, siteshoni yamagetsi, foloko yochitira, ndi zina zotero; kupereka chithandizo kwa foloko reaction; kukweza zitsulo khola, ngalande konkire, kugwira nthaka, etc.;
4. Excavator: kusanja malo, kuchotsa slag, etc.
二.Ntchito yomanga milu yozungulira yachitsulo yozungulira
1. Kukonzekera kwa zomangamanga
Ntchito yaikulu yokonzekera kumanga ndi kusanja malo. Popeza chobowoleracho ndi chachikulu ndipo chili ndi zida zambiri zothandizira, pali zofunika zina zopezera njira ndi nsanja zogwirira ntchito. Chifukwa chake, kukonzekera zomanga kuyenera kuganizira njira zomangira ndi ndege zogwirira ntchito zomwe zimafunikira kuti zizigwira ntchito monga mulu wazitsulo zopangira zitsulo ndi kupanga, mayendedwe a slag, kukweza ndi kuyika konkire yachitsulo, ndikutsanulira konkriti.
2. Muyeso ndi masanjidwe
Choyamba, yang'anani mosamala zogwirizanitsa, kukwera ndi zina zofunikira zomwe zimaperekedwa ndi zojambula zojambula. Mukatsimikizira kuti ndi zolondola, gwiritsani ntchito siteshoni yonse kuti muyale muluwo. Muluwo ukayalidwa, jambulani mzere wopingasa pakati pa miluyo mpaka 1.5m kutali ndikupanga chizindikiro choteteza mulu.
3. Injini yayikulu yozungulira kwathunthu m'malo mwake
Mfundoyo ikatulutsidwa, kwezani chassis yozungulira, ndipo pakati pa chassis kuyenera kugwirizana ndi pakati pa muluwo. Kenako kwezani injini yayikulu, yikani pa chassis, ndipo pamapeto pake yikani foloko yochitira.
4. Kwezani ndikuyika chosungira chachitsulo
Injini yayikulu ikatha, kwezani ndikuyika choyikapo chitsulo.
5. Kuyeza ndi kusintha verticality
Pambuyo pobowola makina ozungulira, gwiritsani ntchito kubowola mozungulira, ndikusindikiza pansi pa casing pamene mukuzungulira kuti muyendetse casing, kotero kuti casing ikhoza kuponyedwa mwamsanga mu mapangidwe. Pobowola chotengera chachitsulo, gwiritsani ntchito chingwe chowongolera kuti musinthe mowongoka munjira ya XY.
6. Kubowola m'khola ndi kuchotsa nthaka
Pomwe bowolo limabowoleredwa pansi, chobowola chimagwiritsidwa ntchito kutulutsa chidebe cham'kati mwa khoma mpaka pansi pa dzenje kuti atulutse dothi pogwira kapena kugwiritsa ntchito chobowola chozungulira kuti achotse dothi.
7. Kupanga ndi kukhazikitsa khola lachitsulo
Pambuyo pobowola mpaka pamalo okwera, yeretsani dzenjelo. Pambuyo podutsa kuyendera ndi kuvomerezedwa ndi kufufuza kwa nthaka, kuyang'anira ndi Party A, ikani khola lachitsulo.
8. Kuthira konkire, kutulutsa m'bokosi, ndi kuthira mulu
Pambuyo pa khola lachitsulo, tsanulirani konkire. Pambuyo pa konkire idzatsanuliridwa pamtunda wina, tulutsani chosungiracho. Chophimbacho chikhoza kutulutsidwa pogwiritsa ntchito makina ojambulira chitoliro kapena makina akuluakulu ozungulira.
三,. Ubwino womanga mozungulira:
1 Ikhoza kuthetsa milu yomanga m'malo apadera, zochitika zapadera zogwirira ntchito ndi strata zovuta, popanda phokoso, palibe kugwedezeka ndi chitetezo chapamwamba;
2 Sagwiritsa ntchito matope, malo ogwirira ntchito ndi oyera, amatha kupeŵa kuthekera kwa matope kulowa mu konkire, zomwe zimathandiza kupititsa patsogolo mphamvu ya mgwirizano wa konkire kuzitsulo zazitsulo; imalepheretsa kubwereranso kwa nthaka, sikukanda khoma la dzenje pokweza kubowola ndikutsitsa khola lachitsulo, ndipo imakhala ndi zinyalala zochepa zoboola;
3 Popanga chobowolera, imatha kuweruza mwachidwi mawonekedwe a stratum ndi miyala;
4 Liwiro lobowola limakhala lachangu, lomwe lingafikire pafupifupi 14m/h pamagawo onse a nthaka;
5 Kubowola kuya ndi kwakukulu, ndipo kuya kwakukulu kumatha kufika pafupifupi 80m molingana ndi nthaka yosanjikiza;
6 Kuyima kwa dzenje ndikosavuta kumva, ndipo kutsika kwake kumatha kukhala kolondola mpaka 1/500;
7 Sizophweka kupanga kugwa kwa dzenje, khalidwe la dzenje ndi lalitali, pansi ndi loyera, liwiro liri mofulumira, ndipo matope amatha kuchotsedwa pafupifupi 30mm;
8 Bowo la dzenje ndilokhazikika ndipo coefficient yodzaza ndi yaying'ono. Poyerekeza ndi njira zina zopangira dzenje, konkire yambiri imatha kupulumutsidwa.
Bowo lobowolalo lidaphwa kwambiri chifukwa dothi lodzazira kumbuyo linali lokhuthala komanso lokhala ndi miyala yayikulu.
Kupanga bowo mphamvu ya zonse casing
Zobowola mozungulira kwathunthu sizimagwiritsidwa ntchito pomanga maziko a milu m'magawo osiyanasiyana ovuta monga quicksand, karst landforms, ndi kubweza kwapamwamba kwambiri, komanso atha kugwiritsidwa ntchito pomanga milu yoluma, mizati yazitsulo zapansi panthaka, ndikuchotsa milu.
