Malinga ndi Code for Anti-freezing Design of Hydraulic Structures, konkire ya F400 idzagwiritsidwa ntchito pazinthu zofunika kwambiri, zozizira kwambiri komanso zovuta kukonzanso m'madera ozizira kwambiri (konkritiyo imatha kupirira kuzungulira kwa 400 kuzizira). Malinga ndi izi, konkire ya F400 idzagwiritsidwa ntchito popanga thabwa lakumaso ndi chala chakumaso pamwamba pa madzi akufa pamwamba pa dziwe la rockfill la Huanggou Pumped Storage Power Station, malo osinthika amadzi olowera kumtunda wakumalo olowera ndikutuluka, kusinthasintha kwamadzi malo olowera pansi ndi malo ena olowera. Izi zisanachitike, panalibe chitsanzo chogwiritsa ntchito konkriti ya F400 m'makampani opangira magetsi apamadzi. Pofuna kukonzekera konkire F400, gulu la zomangamanga anafufuza mabungwe kafukufuku zoweta ndi opanga konkire admixture m'njira zambiri, anapatsa makampani akatswiri kuchita kafukufuku wapadera, anakonza F400 konkire powonjezera silika fume, wothandizila mpweya, mkulu-mwachangu kuchepetsa wothandizila madzi ndi zipangizo zina, ndipo ntchito pomanga Huanggou Pumped Storage Power Station.
Kuonjezera apo, m'madera ozizira kwambiri, ngati konkire ikukhudzana ndi madzi imakhala ndi ming'alu yaing'ono, madziwo adzalowa mu ming'alu m'nyengo yozizira. Ndi kuzizira kosalekeza-kusungunuka, konkire idzawonongeka pang'onopang'ono. Silabu ya konkriti ya dambo lalikulu la nkhokwe ya kumtunda kwa malo opangira magetsi opopera imagwira ntchito yosunga madzi komanso kupewa kuti asasewere. Ngati pali ming'alu yambiri, chitetezo cha damu chidzachepa kwambiri. Gulu lomanga la Huanggou Pumped Storage Power Station lapanga mtundu wa konkire wosamva ming'alu - kuwonjezera zowonjezera zowonjezera ndi ulusi wa polypropylene posakaniza konkire kuti muchepetse ming'alu ya konkire ndikuwonjezera kukana kwachisanu kwa konkire ya slab.
Bwanji ngati pankhope ya konkire ya damu pakhala ming'alu? Gulu la zomangamanga lakhazikitsanso mzere wotsutsa chisanu pamwamba pa gululo - pogwiritsa ntchito polyurea yopukutira pamanja ngati chophimba choteteza. Dzanja scraped polyurea akhoza kudula kukhudzana pakati konkire ndi madzi, m'mbuyo chitukuko cha amaundana-thaw makulitsidwe kuwonongeka kwa nkhope slab konkire, komanso kupewa zosakaniza zina zoipa m'madzi kukokoloka konkire. Imakhala ndi ntchito zoletsa madzi, odana ndi ukalamba, amaundana kukana kusungunuka, etc.
Damu lakumaso la konkriti la rockfill silimaponyedwera nthawi imodzi, koma limapangidwa m'zigawo. Izi zimabweretsa mgwirizano wamapangidwe pakati pa gawo lililonse. Chithandizo chodziwika bwino cha anti-seepage ndikuphimba chivundikiro cha rabara pagulu lolumikizana ndikulikonza ndi mabawuti okulitsa. M'nyengo yozizira m'madera ozizira kwambiri, malo osungiramo madzi amatha kukhala ndi icing yowonjezereka, ndipo mbali yowonekera ya bolt yowonjezera idzaundana pamodzi ndi ayezi kuti awononge madzi oundana. Huanggou Pumped Storage Power Station imagwiritsa ntchito mawonekedwe amtundu wopindika, womwe umathetsa vuto la mafupa owonongeka ndi kutulutsa ayezi. Pa Disembala 20, 2021, gawo loyamba la Huanggou Pumped Storage Power Station lidzayamba kugwira ntchito yopanga magetsi. Opaleshoni yozizira yatsimikizira kuti mawonekedwe amtunduwu amatha kuletsa kuwonongeka kwa maulalo omangika chifukwa cha kukoka kwa ayezi kapena kukulitsa chisanu.
Kuti amalize kumanga ntchitoyi mwamsanga, gulu lomanga linayesetsa kumanga m’nyengo yozizira. Ngakhale kuti palibe kuthekera komanga kunja kwa nyengo yozizira, nyumba yamagetsi yapansi panthaka, ngalande yotumizira madzi ndi nyumba zina za pompano zosungirako magetsi zimakwiriridwa mozama pansi ndipo zimakhala ndi mikhalidwe yomanga. Koma bwanji kutsanulira konkire m'nyengo yozizira? Gulu la zomangamanga likhazikitse zitseko zotsekera pazitseko zonse zolumikiza mapanga apansi panthaka ndi kunja, ndikuyika mafani a mpweya wotentha wa 35kW mkati mwa zitseko; Dongosolo losanganikirana la konkriti latsekedwa kwathunthu, ndipo zida zotenthetsera zimayikidwa m'nyumba. Musanayambe kusakaniza, sambani makina osakaniza konkire ndi madzi otentha; Kuwerengera kuchuluka kwa coarse ndi zabwino aggregates m'nyengo yozizira malinga ndi kuchuluka kwa konkire earthwork zofunika yozizira kuthira, ndi kuwatengera ku ngalande kusungiramo dzinja. Gulu la zomangamanga limatenthetsanso maguluwo asanasakanizidwe, ndikuyika "zovala za thonje" pamagalimoto onse osakaniza omwe amanyamula konkire kuti atsimikizire kuti kutentha kumasungidwa panthawi yoyendetsa konkire; Pambuyo pa kutsanula koyamba kwa konkriti, pamwamba pa konkire iyenera kuphimbidwa ndi quilt yotenthetsera kutentha ndipo, ngati n'koyenera, yokutidwa ndi bulangeti yamagetsi yotenthetsera. Mwanjira imeneyi, gulu lomangalo linachepetsa kukhudzidwa kwa nyengo yozizira pa ntchito yomangayo.
