Mikana yekushandisa uye zvinonetsa zvegirazi fiber uye zvinhu zvinosanganiswa mumunda wezvivakwa

Nhasi ndinoda kugovera chinyorwa newe:

Makumi gumi apfuura, nhaurirano pamusorozvivakwayaitenderera pakuti imarii yakawedzerwa kuigadzirisa. Asi nhasi kune kusimba kuri kuwedzera kwekusimba nekusimba muzvirongwa zvinosanganisira kuvaka kana kugadziriswa kwemigwagwa yenyika, mabhiriji, zviteshi, magetsi emagetsi, nezvimwe.

Indasitiri inosanganiswa inogona kupa mhinduro dzakasimba dziri kutsvagwa nenyika dzeUS. Nekuwedzera kwemari, sezvakarongwa mubhiri re $ 1.2 trillion yezvivakwa, masangano ehurumende yeUS achange aine mari yakawanda nemikana yekuyedza matekinoroji nemaitiro ekuvaka.

Greg Nadeau, Sachigaro uye CEO weInfrastructure Ventures, akati, "Kune mienzaniso mizhinji muUnited States yese uko kushandiswa kwehunyanzvi hwekugadzira kwakaratidza kushanda, angave mabhiriji kana zvivakwa zvekuvaka zvakasimbiswa. Kukanganisa kukuru kweBridge Infrastructure Act pamusoro pemari yenguva dzose Mari iyi inopa mukana wekuti nyika dzishandise mari idzi kuwedzera kushandiswa nekunzwisisa kwezvimwe zvinhu izvi. Hazvisi zvekuedza, zvinoratidzwa kuti zvinoshanda. "

Composite zvinhuakashandiswa kugadzira mamwe mabhiriji anoshingirira. Mabhiriji muUS kumahombekombe uye kuchamhembe nyika dzinoshandisa munyu mumigwagwa munguva yechando dzakaora nekuda kwekuora kwesimbi mukongiri yakasimbiswa uye zvivakwa zvekongiri zvakasimbiswa. Kushandisa zvinhu zvisingaore zvakaita sembabvu dzakaumbwa zvinogona kuderedza mari inofanira kushandiswa neMadhipatimendi Ezvekufambisa eUnited States (DOTs) pakugadzirisa nekugadzirisa mabhiriji.

Nadeau akati: “Kazhinji, mabhiriji enguva dzose ane upenyu hwakarongwa hwemakore 75 anofanirwa kurapwa zvikuru mukati memakore 40 kana kuti 50. Kushandisa zvisiri zvekuora zvichibva pakusarudza kwako zvinhu zvinogona kuwedzera hupenyu hwesevhisi uye kuderedza kutenderera kwehupenyu hurefu. mari.”

Kune kumwe kuchengetwa kwemutengo zvakare. “Kudai taiva nechinhu chisingaore, magadzirirwo ekongiri angadai akasiyana. Semuyenzaniso, hatingafaniri kushandisa corrosion inhibitors, iyo inodhura madhora makumi mashanu pacubic yadhi,” akadaro Purofesa weYunivhesiti yeMiami uye Director weDhipatimendi reCivil and Architectural Engineering Director Antonio Nanni akadaro.

Mabhiriji anovakwa nezvinhu zvakaumbwa anogona kugadzirwa ane mamwe akakwenenzverwa ekutsigira zvimiro. Ken Sweeney, Mutungamiriri uye Mukuru Injiniya weAdvanced Infrastructure Technologies (AIT), akati: “Dai wanga uchishandisa kongiri, waizoshandisa mari yakawanda nezviwanikwa kuvaka bhiriji kuti ritsigire huremu hwaro, kwete basa raro, Kureva kutakura traffic. Kana iwe ukagona kuderedza huremu hwayo uye uine yakakwira simba-ku-huremu reshiyo, ingave bhenefiti huru: zvingave zvakachipa kuvaka. "

Nekuti mabhawa anoumbwa akareruka kupfuura simbi, marori mashoma anodiwa kutakura mabhawa akaumbwa (kana mabhiriji akagadzirwa kubva kune akaumbwa mabhawa) kuenda kunzvimbo yebasa. Izvi zvinoderedza kubudiswa kwecarbon dioxide. Makondirakiti anogona kushandisa makireni madiki, akaderera-mutengo wakaderera kusimudza zvikamu zvebhiriji munzvimbo, uye zviri nyore uye zvakachengeteka kuti vashandi vekuvaka vatakure.
