NgokweKhowudi yoYilo lokuLwa nokuQhotsa kweZakhiwo zeHydraulic, ikhonkrithi ye-F400 mayisetyenziselwe iindawo zezakhiwo ezibalulekileyo, eziqandisiweyo kakhulu kwaye kunzima ukuzilungisa kwiindawo ezibandayo kakhulu (ikhonkrithi mayikwazi ukumelana nemijikelo yokuqandisa engama-400). Ngokwesi sikhokelo, ikhonkrithi ye-F400 mayisetyenziselwe i-face slab kunye ne-toe slab ngaphezulu komgangatho wamanzi ofileyo kwidama eliphezulu le-reservoir face rockfill le-Huanggou Pumped Storage Power Station, indawo yokuguquguquka kwamanzi kwi-inlet ephezulu ye-reservoir kunye ne-outlet, indawo yokuguquguquka kwamanzi kwi-inlet ephantsi ye-reservoir kunye ne-outlet kunye nezinye iindawo. Ngaphambi koku, bekungekho mzekelo wokusetyenziswa kwekhonkrithi ye-F400 kwishishini lamandla ombane wasekhaya. Ukuze kulungiswe ikhonkrithi ye-F400, iqela lokwakha liphande amaziko ophando asekhaya kunye nabavelisi bokuxuba ikhonkrithi ngeendlela ezininzi, lanika iinkampani zobungcali igunya lokwenza uphando olukhethekileyo, lalungisa ikhonkrithi ye-F400 ngokongeza i-silica fume, i-air entraining agent, i-arhente yokunciphisa amanzi esebenza kakuhle kunye nezinye izinto, laza layisebenzisa ekwakheni iHuanggou Pumped Storage Power Station.
Ukongeza, kwiindawo ezibandayo kakhulu, ukuba ikhonkrithi edibana namanzi ineemingxunya ezincinci, amanzi aya kungena kwiimingxunya ebusika. Ngomjikelo wokuqandisa nokunyibilika okuqhubekayo, ikhonkrithi iya kutshatyalaliswa kancinci kancinci. I-face slab yekhonkrithi yedama eliphambili ledama eliphezulu lesikhululo samandla sokugcina amanzi esimpompiweyo idlala indima yokugcina amanzi kunye nokuthintela ukuvuza kwamanzi. Ukuba kukho iimingxunya ezininzi, ukhuseleko lwedama luya kuncipha kakhulu. Iqela lokwakha leSikhululo saMandla sokuGcina i-Huanggou Pumped Storage liphuhlise uhlobo lwekhonkrithi engaqhekekiyo - yongeza i-arhente yokwandisa kunye nefayibha ye-polypropylene xa kuxutywa ikhonkrithi ukunciphisa ukuvela kweemingxunya zekhonkrithi kunye nokuphucula ngakumbi ukumelana neqhwa kwekhonkrithi ye-face slab.
Kuthekani ukuba kukho imingxunya ebusweni bekhonkrithi yedama? Iqela lokwakha likwamisele umgca wokumelana nomkhenkce kumphezulu wephaneli - besebenzisa i-polyurea ekhutshiweyo ngesandla njengengubo yokukhusela. I-polyurea ekhutshiweyo ngesandla inokuphelisa ukudibana phakathi kwekhonkrithi namanzi, inciphise uphuhliso lomonakalo wokuqhaqhazela kwekhonkrithi yeslab yobuso, kwaye ithintele nezinye izithako eziyingozi emanzini ekuboleni kwekhonkrithi. Inemisebenzi yokumelana namanzi, ukulwa nokwaluphala, ukumelana nokunyibilika komkhenkce, njl.njl.
I-face slab yedama le-concrete face rockfill ayiphoswanga ngaxeshanye, kodwa yakhiwe ngamacandelo. Oku kubangela ukuba kubekho i-structural joint phakathi kwecandelo ngalinye lephaneli. Unyango oluqhelekileyo oluchasene nokuvuza kukuvala ipleyiti yerabha kwi-structural joint kwaye uyilungise ngee-expansion bolts. Ebusika kwiindawo ezibandayo kakhulu, indawo ye-reservoir iya kuba phantsi kwe-icing etyebileyo, kwaye inxalenye ebonakalayo ye-expansion bolt iya kubanda kunye ne-ice layer ukuze kubangele umonakalo wokutsalwa komkhenkce. I-Huanggou Pumped Storage Power Station isebenzisa ngendlela entsha isakhiwo sohlobo lwe-compressable coating, esisombulula ingxaki ye-structural joints eyonakaliswe kukutsalwa komkhenkce. Ngomhla wama-20 kuDisemba ngo-2021, iyunithi yokuqala ye-Huanggou Pumped Storage Power Station iya kuqaliswa ukusebenza ukuvelisa umbane. Umsebenzi wasebusika ubonakalise ukuba olu hlobo lwesakhiwo lunokuthintela umonakalo we-structural joints zephaneli ezibangelwa kukutsalwa komkhenkce okanye ukukhutshwa kwe-frost expansion.
Ukuze kugqitywe ukwakhiwa kweprojekthi ngokukhawuleza, iqela lokwakha lizame ukwenza ulwakhiwo lwasebusika. Nangona kungekho ndlela yokuba kwakhiwe ngaphandle ebusika, i-powerhouse engaphantsi komhlaba, i-water transportance tunnel kunye nezinye izakhiwo zesikhululo samandla sokugcina amanzi zigqunywe nzulu ngaphantsi komhlaba kwaye zineemeko zokwakha. Kodwa ungagalela njani ikhonkrithi ebusika? Iqela lokwakha liza kuseta iingcango zokuthintela ubushushu kuzo zonke iindawo ezivulekileyo ezidibanisa imiqolomba engaphantsi komhlaba kunye neyangaphandle, kwaye lifake iifeni zomoya oshushu ezingama-35kW ngaphakathi kweminyango; Inkqubo yokuxuba ikhonkrithi ivaliwe ngokupheleleyo, kwaye izixhobo zokufudumeza zibekwe ngaphakathi. Ngaphambi kokuxuba, hlamba inkqubo yokuxuba ikhonkrithi ngamanzi ashushu; Bala ubungakanani bee-aggregates ezirhabaxa nezicolekileyo ebusika ngokwenani le-concrete earthwork efunekayo yokugalela ebusika, kwaye uzithuthele kwi-tunnel ukuze zigcinwe ngaphambi kobusika. Iqela lokwakha likwafudumeza ii-aggregates ngaphambi kokuxuba, kwaye libeka "impahla egqunywe yikotoni" kuzo zonke iilori zokuxuba ezithutha ikhonkrithi ukuqinisekisa ukuba ubushushu bugcinwa ngexesha lokuthuthwa kwekhonkrithi; Emva kokuseta kokuqala kokugalela ikhonkrithi, umphezulu wekhonkrithi kufuneka ugutyungelwe nge-thermal insulation quilt kwaye, ukuba kuyimfuneko, ugutyungelwe ngengubo yombane yokufudumeza. Ngale ndlela, iqela lokwakha lanciphisa impembelelo yemozulu ebandayo kulwakhiwo lweprojekthi.
