Matanho ekugadzira zero-carbon tunnels

Kunyangwe paine inotyisa yenguva yakatarwa neParis Accord, zero-carbon tunnels dziri mukati mekusvikika kana mhinduro dzakakodzera dzikaitwa.

Indasitiri yetunneling iri padanho rekusimudzira uko kusimba uye decarbonisation iri pamusoro pemaajenda evatariri. Kuzadzisa chinangwa chekuchinja kwemamiriro ekunze che1.5 ° c panosvika gore ra2050, indasitiri yetunneling ichada kudzikisa kuburitsa kwakananga CO2 kusvika ku zero.

Parizvino nyika shoma uye zvirongwa zvezvivakwa zviri "kufamba hurukuro" uye kutora danho rekudzikisa kabhoni. Zvichida Norway ndiyo imwe nyika inotungamira nzira, uye, sezvakaita misika yavo yemotokari yemagetsi, midziyo yekuvaka yemagetsi iri kuwedzera kushandiswa, nemaguta makuru achange aine carbon neutral kuvaka panosvika 2025. Kunze kweNorway, nyika shoma uye mapurojekiti muEurope semuenzaniso. , varikumisikidza zvinovavarira kudzikisa kabhoni, asi kazhinji nekungotarisa chete kugadzira yakaderera kabhoni kongiri misanganiswa.

Indasitiri yetunneling inopa kuburitswa kwepasi rose CO2 uye ine basa rekuita mukuderedza kabhoni. Iyo indasitiri yakatarisana nekuwedzera kumanikidzwa kubva kune vanogadzira marongero, vanoisa mari, uye vatengi kune decarbonise mashandiro.

Kana danho ratorwa rekuvaka mugero mutsva, dhizaini yakangwara inoteverwa nekuvaka kwakanaka kwakanangana nekabhoni kunozopedzisira kwakonzera kudzikiswa kwemitengo yeprojekiti.

Nepo vamwe vachitenda kuti yakaderera kabhoni tunneling yakaenzana nemitengo yepurojekiti yepamusoro, parizvino maitiro akanakisa mukutonga kabhoni muindasitiri yekuvaka anoratidza neimwe nzira, uye kuburikidza nemaitiro akazara mukati mehupenyu hwepurojekiti, mainjiniya akatarisana nekuchengetedza kabhoni, izvi zvinopa mutengo wese wepurojekiti. zvakare! Aya ndiwo maitiro ari kuseri kweyakajairwa PAS2080 kuCarbon Management muInfrastructure uye yakakodzera kushandisa pamapurojekiti kune avo vanoda decarbonisation.

Tichifunga nezvechishuviro ichi chiri kukura uye kuda kwedecarbonisation, heano masendi angu mashanu: zvinhu zvitatu zvakakosha zvingakuchidzira kuedza kwekubvisa kaboni uye kuita kusundira mberi kuzadzisa chinangwa chekuchinja kwemamiriro ekunze che1.5 ° C - Vaka hungwaru, kuvaka zvine hungwaru, uye kuvaka hupenyu hwose.

Vaka zvakangwara - Izvo zvese zvinotanga nehunyanzvi uye nehanya dhizaini

Iwo makuru decarbonisation anowanikwa mumatanho anouya kubva kusarudzo pamatanho ekuronga uye ekugadzira. Sarudzo dzepamberi dzezvirongwa zvinogoneka dzakakosha kune kabhoni nyaya, kusanganisira yekuvaka zvachose, kana kutarisa kukwidziridza kana kuwedzera hupenyu hwezvinhu zviripo usati watsvaga nzira itsva yekuvaka.

Saka, iko kwekutanga mudanho rekugadzira kuti misiyano yakakosha inoitwa, uye mumatanho ndiyo dhizaini umo chikamu chikuru chekuchengetedza kabhoni chinogona kuitwa. Mabhenefiti edhizaini akadai anogona kuitwa zviri nyore pamapurojekiti emugero kuburikidza nehutungamiriri hwevatengi, semuenzaniso kukurudzira nzira dzekutenga dzinokwezva makondirakiti makuru kuti ape maitiro ekugadzirisa kabhoni ekudzikisa uye zvinhu, izvo zvinosimudzira yakakura tekinoroji yekugovera cheni.

Mukuvhurika kumeso, kupfapfaidza kongiri yedombo kutsigirwa kunoshandiswa pasi rose, uye munyika dzakawanda pasirese, kupihwa hupamhi hwayo, yakave yakagamuchirwa zvakanyanya kune isingaperi tunnel linings, iyo inochengetedza pakati pe20-25% yekongiri inoshandiswa mumigero yakajairika. lining systems. Ini ndinotenda kuti mazuva ano akapfapfaidzwa kongiri masisitimu nhasi, achibatanidza akakwira mazinga ePortland Cement kutsiva, polymer fiber uye hunyanzvi hwekudzivirira mvura tekinoroji, zvinopa mikana yekugona kuwana pamusoro pe50% kudzikiswa kwekabhoni mumatanho edu. Asi zvakare, idzi 'Vaka Hungwaru' mhinduro dzinofanirwa kutorwa uye kuitiswa panguva yekutanga dhizaini nhanho kuti uwedzere iyo yakakura kuchengetedza kabhoni. Idzi ndidzo mhinduro dzechokwadi dzekupa kuchengetedza chaiko, uye isu tinogona kuita aya nhanho hombe nhasi neiyo chaiyo timu tsika, dhizaini chaiyo, uye yakabatanidzwa kune inonakidza mhando dzekutenga dzinomanikidza zvinhu zvakanaka kuti zviitike.

Sekudivi kwetete, dambudziko kune yakaderera kabhoni yakapfapfaidzwa kongiri ndiyo inononoka simba kuwana mumaawa mashoma ekutanga mushure mekupfapfaidza. Kuwana simba rekutanga kwakakosha pakuchengetedzwa kwepamusoro uye kubereka mukuvaka akakora akakwana. Zvidzidzo zvinofadza zvatakagadzira nema geopolymers (misanganiswa isina simende yePortland) zvakaratidza kuti tinogona kuwana ultra-low kabhoni kongiri nekukurumidza kuwana simba rekutanga, kunyangwe isu tichiramba tichivandudza inodiwa yenguva refu kuita kuti misanganiswa iyi ishande.

Nhanho inotevera yatingatore takanangana nekabhoni zero tunnel ndeyekunyanya-inoshanda mukati memaitiro ekuvaka.

Kwekutanga kutarisisa - Strategic kudyidzana mukugadzira uye kubatana nemakontrakta uye cheni yekugovera.

Yakaderera uye yakaderera kabhoni yakapfapfaidza kongiri lining zvinhu. New accelerators uye membranes ndiwo akakosha.

BEV yakavakirwa huwandu hweSC tunneling michina yemadhayamita makuru emugero.

SC digitalisation kusimbisa dhizaini. Gadzira realtime SmartScan uye dijitari ecosystems kuburikidza neindasitiri kubatana.

Kudzidziswa kweSimulator, kubvumidzwa kweEFNARC, kuenderera mberi nekuvandudza, kuwedzera kuvandudza komputa inobatsira kupfapfaidza.

Vanhu ndivo kiyi pakugadzira yakaderera kabhoni SCL tunneling basa. Hazvibvi mumutemo wehurumende. Vashandi vechirongwa vanofanira kutungamira.

Maitiro akazara ekugadzira tunnel dhizaini uye kuvaka inodiwa kuti decarbonise indasitiri. Imwe neimwe nhanho yekuita inopa yakakosha kabhoni kuchengetedza chikamu.

Vaka zvinobudirira - Smart midziyo, vanhu uye digitalisation

Kuedza kwakawanda kunozodikanwa kugadzirisa iwo makuru masosi ekuburitsa uye decarbonise. Zviito zvakadaro zvinosanganisira danho rekutsvagisa, kushandiswa kwakasarudzika kwemafuta ekufambisa, magetsi ekutyaira, pamwe nekuchinja kune vanopa magetsi egirini kuti tipe simba zvirongwa zvedu zvekuvaka tunnel.

Muenzaniso wekupa kwedu kwakasimba ndeyedu SmartDrive bhatiri mota dzemagetsi. SmartDrive inopa kuvandudzwa kwekuita ne zero emissions emunharaunda. Vanobvisawo mari yekufambisa mafuta nemafuta uye vane mutengo wakaderera wekugadzirisa michina. Semuenzaniso, maNorwegian tunnel makondirakiti ari kutoshanda kusvika 2050 kabhoni net zero zvinangwa nekushandisa SmartDrive Spraymec 8100 SD marobhoti ekupfapfaidza achichajwa achishandisa hydropower grid magetsi. Isu tinotangawo kuona izvi mumapurojekiti ekumigodhi ari kure uko mafekitari emagetsi emugodhi anopa simba rekuchaja bhatiri rezvikepe zvemigodhi. Iyi i net zero uye 2050 yakagadzirira.

Chakakosha kudzikisa kabhoni kutanga kuyera uye kumisikidza mashandisiro edu kabhoni mumapurojekiti ekugadzirisa nhasi - Isu tinofanirwa kugadzira hwaro hwekuti tiite benchmark kuitira kuti tive nereferensi yekuvandudza mutambo wedu. Kuti ndiite izvi ndinofungidzira shanduko yedhijitari mukupfapfaidza kongiri, ndichishandisa mapuratifomu ekuwana data anodhonza zvinyorwa kubva kune yedu yepasi pemidziyo, batch zvidyarwa nezvimwe, asiwo akangwara uye chaiwo-nguva 3D scanning masisitimu pameso ekuchera anotsigira marobhoti nozzle vanoshanda " kuiwana chaiko kekutanga” pavanogona kupfapfaidza kungave kune inodiwa chimiro kana ukobvu. Aya masisitimu anozotsigirawo mainjiniya kuti aongorore kushandiswa kwezvinhu, geology, uye mhando semuenzaniso. Muchokwadi-chaiyo-nguva mapatya edhijitari ichave yakakosha kune vese vane chekuita uye ichafambisa ongororo yezuva nezuva yekabhoni uye kuderedzwa kwemutengo, uku uchiwana kudzora, nzira dzakachengeteka.

Virtual chaiyo yekudzidzisa mapuratifomu evashandisi akakosha ari kutanga muindasitiri yedu uye Normet's VR Sprayed Concrete Simulator, yakatsigirwa neInternational EFNARC C2 certification scheme, ndiyo yazvino muenzaniso inobvumira vashandi venozzle kukwenenzvera hunyanzvi hwavo munzvimbo yekirasi. Aya masimulator anokurudzira nzira dzakachengeteka, dzakasimba dzekupfapfaidza uye kuratidza nzvimbo dzekuvandudza, zvichibatsira kune ava vanodzidzira kukudziridza hunhu hwakanaka uye maitiro anodiwa munzvimbo chaiyo yepasi pevhu.

Vaka kwehupenyu hwese

Isu ntinofanirwa kunge tiri vashoma venzanga inorasa, kunyanya kunyangwe muhupenyu hwedu hwekuita! Normet kuvaka midziyo kuti igare, uye kwese kwatinogona isu tinodzokorora nekugadzirisa zvakare zvikamu uye zvekushandisa kuvaka midziyo mitsva nezvinhu zvitsva zvekuvaka.

Uyezve, kana isu tisingafanirwe kuvaka matanoro matsva, tinogona kupa nzira dzekupa hupenyu hutsva hwekushanda kune dzakaneta uye dzakasakara zviripo zvepasi pevhu tichishandisa kure, kwakaringana maturusi ekuongorora maturusi, akasanganiswa nehurongwa hwehungwaru hwekudzoreredza matekinoroji uye maitiro.

Chekupedzisira, ngatikurudzirei kushandiswa kwekabhoni yakapfapfaidzwa kongiri tekinoroji kuvaka zvimwe zvivakwa zvakatsiga kutsigira hupenyu huri nani kunharaunda dzedu dzazvino nedzemangwana. Hunhu hwepamusoro hwenharaunda hwave kutoyerwa nekufarirazve kwakawedzera simba muzvirongwa zvepasi pevhu rekuchengetedza simba, senge pombi yehydro uye inotarisirwa kuchengetedza hydrogen, asiwo yakaderera purojekiti mugero mhinduro kubatanidza zvachose nharaunda dzedu dziri kure.

Muchidimbu, kuedza kwakawanda pamatanho akasiyana-siyana kunodiwa kukurumidza kuedza decarbonation. Haisi kungoita yakaderera kabhoni kongiri. Tese tine rimwe basa rekuita, saka ngatisvike pazviri uye tive nekwakakodzera, "yakaderera-carb" tunnel.
