Rova simbi yedombo
Nekukurumidza kusimukira kweindasitiri yekuvaka, zvinodikanwa zvezvishandiso mumapurojekiti ekuvaka zviri kuramba zvichiwedzera kuomarara, kunyanya maererano nekusimba uye kutenderera kwehupenyu, izvo zvinoda zvinhu kuti zvikwanise kuenderana neakasiyana nharaunda. Zvisinei, mutsika Concrete Structures, kuparara kwesimbi uye kuputika kwekongiri zvinowanzoitika, kunyanya munzvimbo dzakaoma dzakadai segungwa uye munyu, izvo zvinoisa mungozi kune kuchengeteka uye hupenyu hwebasa rezvirongwa zvekuvaka. Semhando nyowani yefiber composite zvinhu,basalt fiber composite bar (bfrp) inoshandiswa zvishoma nezvishoma mumigwagwa, mabhiriji uye mapurojekiti emugungwa nekuda kwehuremu hwayo, simba repamusoro uye kusagadzikana kwekuora. Sechinhu chakasimba-chakasimba uye chepamusoro-soro, kongiri yepamusoro-yepamusoro (UHPC) ine dense microstructure uye yakadzika kwazvo permeability coefficient, iyo inogona kunyatso kudzivirira kupinda kwekunze kwekukukurwa kwemidhiya uye kuwedzera kusimba kwechisungo pakati pematrix neBFRP mbariro, kuitira kuti ipe kutamba kwakazara kune epamusoro zvinhu zveBFRP mabhawa. Naizvozvo, musanganiswa wemabhawa eBFRP uye UHPC zvinhu zvakakosha zvikuru kuvandudza kusimba kwenguva refu kwemapurojekiti ekuvaka uye kurebesa hupenyu hwesevhisi yezvivakwa zvekongiri.
Basalt fiber composite kusimbisa inopfuura kusimbiswa kwechinyakare maererano nekushanda, uye panguva imwechete, inoitawo zvakanaka maererano nehupfumi hwehupfumi uye kuchengetedza kwezvakatipoteredza. Nekuda kwesimba rayo rekusimba uye kusagadzikana kwekuora, inogona kuderedza huwandu hwezvinhu zvinoshandiswa kune imwe nhanho, nekudaro ichidzikisa mutengo wepurojekiti ne20%. Mukuwedzera, maitiro ayo anoenderera mberi ekugadzira anoita kuti zvikwanise kugadzirisa maererano nehurefu hwechikamu chemugwagwa, kuderedza longitudinal welding process yekusimbisa simbi, uye kuvandudza kushanda kweinjiniya kuvaka. Panguva imwecheteyo, kushandiswa kwebasalt fiber composite reinforcement inogonawo kuderedza mari yekuchengetedza inokonzerwa nekuora kwesimbi yesimbi, iyo ine hupfumi hwepamusoro munguva refu. Sechishandiso chehunyanzvi chezvivakwa zvekuvaka zvemazuva ano, basalt fiber composite yekusimbisa inotora chinzvimbo chakakosha muindasitiri yekuvaka ine yakasarudzika zvivakwa uye yakakura tarisiro yekushandisa. Nekuenderera mberi kwekuenderera mberi kwehunyanzvi uye nekudzika kwekushandisa, zvinotendwa izvozvo basalt fiber composite kusimbisa ichaita basa rakakosha mundima yekuvaka yeramangwana uye kubatsira mukuvaka kwakasvibira uye kusimudzira kwakasimba.
