Yiyiphi indlela yokuvelisa izixhobo zokunyibilikisa ibhitumene? Ziziphi iiparamitha zokulinganisa?
Emva kokuba isixhobo sokunyibilika sebhitumene silinganiswe ngemitha kwaye silinganiswe, sithululwa kwibhanti lokuhambisa elijikeleza kude. Isixhobo sokunyibilikisa ibhitumene yebhloko sithunyelwa kwibhanti ethambekele ekuhambiseni ngebhanti lokuhambisa, kwaye i-conveyor yebhanti ethambekeleyo ithuthelwa kwi-hopper yokulinda ngaphakathi komxube ukulinda imiyalelo. Kwangaxeshanye, ikhonkrithi kunye nothuthu lwempukane zithuthwa nge-screw conveyor ukuya kwi-metering yazo kunye ne-calibration hoppers zokulinganisa kunye nokulinganisa. Iimveliso zokunciphisa amanzi kunye namanzi zahlulwe ngeempompo zamanzi ezi-centrifugal kunye neemveliso zokunciphisa amanzi. Ikhonkrithi intywiliselwa kwikhonkrithi kwaye ilinganiswe ngemitha kwaye ilinganiswe kwi-metering efanelekileyo kunye ne-calibration hoppers.
Emva kokuba i-metering kunye nokulinganisa kwezixhobo ezahlukeneyo ze-bitumen zokunyibilikisa ibhloko zigqityiwe, ulawulo lwenkqubo yolawulo lukhupha imiyalelo yokuyibeka ngokuthe ngcembe kwi-mixer yokuxuba. Emva kokuba ukuxuba kugqityiwe, umnyango wokulayisha we-mixer uyavulwa, kwaye ikhonkrithi yesamente ikhutshwe kwi-mixer ngokusebenzisa i-dumping bin, kwaye ingena kwinkqubo yomjikelezo wokusebenza olandelayo.
Isixhobo sokunyibilikisa ibhitumene yebhloko sisebenzisa iteknoloji yolawulo oludibeneyo. Ilinganisa kwaye ibonise iiparitha ezisisiseko zebhloko ye-bitumen yokunyibilikisa izixhobo ngexesha langempela ngokusebenzisa i-sensors, iisekethe zokumisela inkqubo, iipaneli zokubonisa, njl. Ngokweendlela ezahlukeneyo zokusebenzisa ikhonkrithi yesamente, inokwahlulwa ibe yimveliso yebhloko yebhitumene yokunyibilikisa izixhobo kunye neprojekthi yokwakha izixhobo zokunyibilikisa ibhitumene. Izikhululo zokuxutywa kwezorhwebo zisetyenziselwa ukusetyenzwa kunye nokuthengisa ikhonkrithi yesamente, ngelixa izikhululo zokuxuba iiprojekthi zokwakha zihlala zivelisa ikhonkrithi yesamente ukusuka ekuqaleni. Kakade ke, iindlela zokondla ngokuthe ngqo kwezi zimbini nazo zahlukile. Ngoko ke, xa ukhetha isikhululo sokuxuba, kuyimfuneko ukuba ukhethe ngokweemfuno zebhloko izixhobo zokunyibilikisa ibhitumene.
Kwimveliso kunye nokusetyenzwa kwezixhobo zokunyibilikisa i-asphalt ye-asphalt usebenzisa i-samente izinzile koomatshini besikhululo sokuxuba umhlaba, ukuze kuhlangatyezwane kakuhle neemfuno zokwakhiwa, izinto ezifunekayo zokuxuba kunye ne-seasoning ratios zonke zingqongqo. Isixhobo sokunyibilikisa i-asphalt esinebloko sijolise kwiimfuno ezinxulumeneyo kumlinganiselo wokusonjululwa kwishishini loomatshini bokuxuba umhlaba wesamente ozinzile. Ubukhulu bobungakanani besayizi ye-particle ye-aggregate e-coarse kwisixhobo sokunyibilikisa i-asphalt yebhloko akufanele idlule i-30mm.
Isixhobo sokunyibilikisa i-bitumen yeBlock inokuvumela ukuba kufakwe ilitye elincinci le-high-grade oversized, kodwa isabelo salo akufanele sidlule i-2%. I-aggregate ye-coarse kufuneka ithathwe ukugcina umlinganiselo wokuxuba udaka, kunye necandelo elincinci lokusabalalisa ubungakanani be-particle akufanele lidlule i-10%. Isabelo selitye elicikizekileyo ngokwe-0.3 ye-hole hole sieve ayikho ngaphantsi kwe-15%. Umlinganiselo wamanzi wesamente yekhonkrithi kwisixhobo sokunyibilikisa i-asphalt ilawulwa ngaphakathi koluhlu lwe-0.4-0.6, ukudilika kwekhonkrithi yi-14-16cm, umlinganiselo wesamente yamanzi wekhonkrithi kufuneka ube yi-38% ~ 45%, kunye nekhonkrithi engaphantsi kwamanzi kufuneka. ziqhutywe kwiiyure ezimbini emva kokuxuba ikhonkrithi. Ikhonkrithi enempazamo enkulu yokulinganisa ukudilika kwisixhobo sokunyibilikisa ibhitumene yebhloko ayinakungena kwi-hopper, kwaye akuvumelekanga ngokungqongqo ukongeza amanzi kwi-hopper.
