Indlela yokukhetha umqobo wokugquma isandi ngaphandle kokwazi iinkcukacha?Xa sifuna umenzi wokuthintela ukugquma kwesandi ukuba asinike isicatshulwa, kufuneka siqale sazi imilinganiselo yesithintelo sokugquma isandi ukuze sibale ngokuchanekileyo ixabiso lolu hlobo lwesithintelo sokugquma isandi.Ke ukuba asiyazi inkcazo kwinqanaba lokuqala, singazikhetha njani iinkcukacha ezihambelana neprojekthi?
1. Isithintelo sesandi sentsimbi
Ukuba isetyenziswe kwiiprojekthi ze-expressway, ngokuqhelekileyo kuya kubakho imidwebo evela kwiziko loyilo, kwaye ixabiso lingabalwa ngokuthe ngqo kwimizobo.Ukuba inani lincinci kwaye akukho mizobo, ngoko kufuneka siyile isicwangciso ngokwemiqathango yesayithi.Ubukhulu bephepha lesinyithi ngokubanzi yi-0.7mm, 0.8mm, 1.0mm, 1.2mm, kwaye ngokubanzi sinokusebenzisa .8mm kwiimfuno eziphantsi, kunye ne-1.0mm okanye i-1.2mm kwiiprojekthi zesantya esiphezulu.
2. Isithintelo sesandi esicacileyo
Imiqobo yesandi ecacileyo yamkelwa ngokuthe ngcembe ziiprojekthi zikamasipala.Isetyenziswe ngokudibeneyo kunye nesithintelo sokugquma isandi sentsimbi, esingenako ukugquma isandi esilungileyo kunye nesiphumo sokunciphisa ingxolo, kodwa sinenkangeleko enhle kunye nesisa, esiluncedo kuyilo lwendlela yedolophu.Isithintelo sokufaka isandi esicacileyo sikwahlulwe kwiglasi elaminethiweyo, ibhodi yePC kunye ne-acrylic.Phakathi kwabo, iglasi ye-laminated esetyenziswa ngokuqhelekileyo yi-5mm + 5mm ubukhulu;Ibhodi yePC ine-4mm-20mm, isetyenziswa ngokuqhelekileyo i-6mm;ibhodi acrylic 8mm-20mm.Oku kungasentla kunokwenziwa ngokwezifiso ngokweemfuno ezithile.
Ukuphakama kobunzima bephepha, ngcono isiphumo sokugquma isandi, kodwa akufuneki silandele ii-decibels zengxolo ephantsi, okoko nje ihlangabezana nemigangatho yokhuseleko lokusingqongileyo kwaye ayichaphazeli ubomi obuqhelekileyo babahlali abasingqongileyo, kungenjalo kuya kuba njalo. ukwandisa kuphela iindleko ngaphandle kwesizathu.
