Raws li Txoj Cai Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Cov Khoom Siv Hluav Taws Xob, F400 pob zeb yuav tsum tau siv rau qhov chaw ntawm cov qauv uas tseem ceeb, khov khov thiab nyuaj rau kev kho nyob rau hauv qhov txias txias (cov pob zeb yuav tuaj yeem tiv taus 400 lub voj voog khov-thaw). Raws li qhov tshwj xeeb no, F400 pob zeb yuav tsum tau siv rau lub ntsej muag slab thiab ntiv taw slab saum toj no cov dej tuag ntawm lub taub dej sab sauv lub ntsej muag rockfill dam ntawm Huanggou Pumped Storage Power Station, qhov dej hloov pauv ntawm thaj chaw sab sauv sab saud thiab qhov hluav taws xob, qhov dej hloov pauv ntawm thaj chaw qis ntawm qhov nkag thiab qhov hluav taws xob. Ua ntej no, tsis muaj qhov ua ntej rau kev thov ntawm F400 pob zeb hauv kev lag luam dej hauv tsev. Txhawm rau npaj F400 pob zeb, pab pawg tsim kho tau tshawb xyuas cov chaw tshawb fawb hauv tsev thiab cov tuam txhab tsim vaj tsev ua vaj tse nyob hauv ntau txoj hauv kev, tau tso siab rau cov tuam txhab tshaj lij los ua cov kev tshawb fawb tshwj xeeb, npaj F400 pob zeb los ntawm kev ntxiv silica fume, air entraining agent, high-efficiency water reduce agent thiab lwm yam ntaub ntawv, thiab siv rau kev tsim kho ntawm Huanggou Pumped Storage Power Station.
Tsis tas li ntawd, nyob rau hauv qhov chaw txias heev, yog tias cov pob zeb sib txuas nrog dej muaj qhov tawg me ntsis, cov dej yuav nkag mus rau hauv cov kab nrib pleb thaum lub caij ntuj no. Nrog rau lub voj voog khov-thaw tas li, cov pob zeb yuav maj mam rhuav tshem. Lub ntsej muag pob zeb ntawm lub pas dej loj ntawm lub pas dej sab saud ntawm qhov chaw tso hluav taws xob tso dej tau ua lub luag haujlwm ntawm kev khaws dej thiab kev tiv thaiv seepage. Yog tias muaj kev tawg ntau heev, kev nyab xeeb ntawm lub pas dej yuav raug txo qis. Pab pawg tsim kho ntawm Huanggou Pumped Storage Power Station tau tsim ib hom kev sib tsoo resistant pob zeb - ntxiv cov neeg sawv cev nthuav dav thiab polypropylene fiber ntau thaum sib xyaw ua vaj tse kom txo tau qhov tshwm sim ntawm cov pob zeb tawg thiab txhim kho cov Frost tsis kam ntawm lub ntsej muag slab pob zeb.
Yuav ua li cas yog tias muaj kab nrib pleb ntawm lub ntsej muag ntawm lub pas dej ua ke? Pab neeg tsim kho kuj tau teeb tsa cov kab Frost tiv thaiv rau saum npoo ntawm lub vaj huam sib luag - siv tes scraped polyurea ua cov txheej tiv thaiv. Tes scraped polyurea tuaj yeem txiav tawm qhov kev sib cuag ntawm pob zeb thiab dej, ua kom qeeb ntawm kev txhim kho khov-thaw scaling kev puas tsuaj ntawm lub ntsej muag slab pob zeb, thiab tseem tiv thaiv lwm yam khoom xyaw hauv dej los ntawm eroding pob zeb. Nws muaj cov dej tsis zoo, tiv thaiv kev laus, khov thawing tsis kam, thiab lwm yam.
Lub ntsej muag slab ntawm pob zeb lub ntsej muag rockfill dam tsis yog cam khwb cia ib zaug, tab sis tsim nyob rau hauv seem. Qhov no ua rau muaj kev sib koom ua ke ntawm txhua pawg vaj huam sib luag. Cov kev kho mob los tiv thaiv kab mob feem ntau yog los npog cov roj hmab npog phaj ntawm cov txheej txheem sib koom ua ke thiab kho nws nrog kev nthuav dav bolts. Nyob rau hauv lub caij ntuj no nyob rau hauv cov cheeb tsam txias heev, lub reservoir cheeb tsam yuav ua rau cov thicker icing, thiab cov exposed bolt ntawm expansion bolt yuav khov ua ke nrog cov dej khov txheej yuav ua rau cov dej khov rub tawm puas. Huanggou Pumped Storage Power Station innovatively txais cov txheej txheem txheej txheej txheej, uas daws cov teeb meem ntawm cov pob qij txha puas los ntawm cov dej khov rub tawm. Thaum Lub Kaum Ob Hlis 20, 2021, thawj chav tsev ntawm Huanggou Pumped Storage Power Station yuav raug muab tso ua haujlwm rau kev tsim hluav taws xob. Kev ua haujlwm lub caij ntuj no tau ua pov thawj tias hom qauv no tuaj yeem tiv thaiv kev puas tsuaj ntawm vaj huam sib luag cov pob qij txha los ntawm cov dej khov rub lossis Frost expansion extrusion.
Txhawm rau ua kom tiav qhov project tsim kom sai li sai tau, pab pawg tsim kho tau sim ua kom tiav kev tsim kho lub caij ntuj no. Txawm hais tias yuav luag tsis muaj peev xwm ntawm kev tsim kho lub caij ntuj no sab nraum zoov, lub tsev tsim hluav taws xob hauv av, qhov dej xa tawm thiab lwm lub tsev ntawm qhov chaw tso hluav taws xob tso hluav taws xob tau muab faus rau hauv av thiab muaj kev tsim kho. Tab sis yuav ua li cas ncuav qhob nyob rau hauv lub caij ntuj no? Pab neeg tsim kho yuav tsum teeb lub qhov rooj thaiv qhov rooj rau tag nrho cov qhov qhib txuas rau hauv av caverns thiab sab nraum zoov, thiab nruab 35kW cua kub kiv cua hauv qhov rooj; Lub pob zeb sib xyaw ua ke raug kaw tag nrho, thiab cov chaw cua sov tau teeb tsa hauv tsev. Ua ntej sib tov, ntxuav lub pob zeb sib tov nrog dej kub; Muab xam cov ntxhib thiab nplua zoo sib sau ua ke nyob rau lub caij ntuj no raws li tus nqi ntawm cov pob zeb hauv av xav tau rau lub caij ntuj no pouring, thiab thauj lawv mus rau hauv lub qhov rau khaws cia ua ntej lub caij ntuj no. Pab neeg tsim kho kuj ua kom sov cov khoom sib xyaw ua ntej sib tov, thiab muab "paj rwb padded khaub ncaws" rau tag nrho cov tsheb thauj khoom sib tov thauj khoom ua vaj tse kom ntseeg tau tias qhov kub thiab txias thaum lub sij hawm thauj khoom ua vaj tse; Tom qab pib qhov chaw ntawm pob zeb, lub pob zeb nto yuav tsum tau them nrog thermal rwb thaiv tsev quilt thiab, yog tias tsim nyog, them nrog hluav taws xob daim pam rau cua sov. Nyob rau hauv txoj kev no, pab neeg tsim kho tau txo qis qhov cuam tshuam ntawm huab cua txias ntawm qhov project tsim.
