1. Itekhnoloji yangasemva
Okwangoku, iisistim ze-WIM ezisekwe kwi-piezoelectric quartz sensors weighting zisetyenziswa ngokubanzi kwiiprojekthi ezifana nokubeka esweni umthwalo omninzi kwiibhulorho kunye neekholvethi, ukunyanzeliswa komthwalo ongekho kwindawo yezithuthi ezithutha uhola wendlela, kunye nolawulo lomthwalo ogqithisileyo wobuchwepheshe. Nangona kunjalo, ukuqinisekisa ukuchaneka kunye nobomi benkonzo, iiprojekthi ezinjalo zifuna ukwakhiwa ngokutsha kwepavement yesamente yepiezoelectric quartz enobunzima bokufakelwa kwenzwa kunye nenqanaba letekhnoloji yangoku. Kodwa kwezinye iimeko zesicelo, ezifana ne-bridge decks okanye iindlela ze-trunk zedolophu kunye noxinzelelo olunzima lwezithuthi (apho ixesha lokunyanga i-samente lide kakhulu, okwenza ukuba ukuvalwa kwendlela yexesha elide kube nzima), iiprojekthi ezinjalo zinzima ukuphumeza.
Isizathu sokuba i-piezoelectric quartz yokulinganisa i-sensor ayinakufakwa ngokuthe ngqo kwi-pavement eguquguqukayo kukuba: Njengoko kuboniswe kuMzobo 1, xa ivili (ingakumbi phantsi komthwalo onzima) lihamba kwi-flexible pavement, indawo yendlela iya kuba ne-subsidence enkulu. Nangona kunjalo, xa ufikelela kwi-quartz eqinile ye-piezoelectric enesisindo sommandla we-sensor, iimpawu ze-subsidence ye-sensor kunye ne-interface yendawo ye-pavement ihluke. Ngaphezu koko, inzwa yokulinganisa eqinile ayinakho ukubambelela ngokuthe tye, okubangela ukuba inzwa yokulinganisa iphuke ngokukhawuleza kwaye ihlukane ne-pavement.
(I-1-wheel, i-2-weight sensor, i-3-soft base layer, i-4-rigid base layer, i-5-flexible pavement, i-6-subsidence area, i-7-foam pad)
Ngenxa yeempawu ezahlukeneyo zokuthomalalisa kunye nee-coefficients ze-friction ye-pavement ezahlukeneyo, izithuthi ezidlula kwi-piezoelectric quartz ene-sensor ye-sensor zifumana ukungcangcazela okukhulu, okuchaphazela kakhulu ukuchaneka kobunzima bubonke. Emva kokunyanzeliswa kwesithuthi sexesha elide, isiza sinomonakalo kunye nokuqhekeka, okukhokelela kumonakalo wenzwa.
2. Isisombululo sangoku kulo mmandla: Ukwakhiwa kwakhona kwePavement ye-Cement Concrete
Ngenxa yengxaki ye-piezoelectric quartz weighing sensors azikwazi ukufakwa ngokuthe ngqo kwipavement ye asphalt, umlinganiselo oxhaphakileyo owamkelwayo kushishino kukwakhiwa ngokutsha kwesamente kwipavumente yesamente yepiezoelectric quartz ene weighting area yofakelo lwesivamvo. Ubude bokwakhiwa ngokutsha ngokubanzi buyi-6-24 yeemitha, kunye nobubanzi obulingana nobubanzi bendlela.
Nangona ulwakhiwo lwesamente lwesamente luhlangabezana neemfuno zamandla okufaka i-piezoelectric quartz weighting sensors kwaye iqinisekisa ubomi benkonzo, imiba emininzi inyanzelisa kanobom ukukhuthazwa kwayo ngokubanzi, ngakumbi:
1) Ulwakhiwo olubanzi lwesamente yokuqina kwakhona kwendlela yabahambi ngeenyawo yantlandlolo kufuna isixa esikhulu seendleko zokwakha.
2) Ukwakhiwa kwakhona kwekhonkrithi yesamente kufuna ixesha elide kakhulu lokwakha. Ixesha lokunyangwa kwepavement yesamente iyodwa idinga iintsuku ezingama-28 (imfuneko eqhelekileyo), ngokungathandabuzekiyo ibangela impembelelo enkulu kumbutho wezothutho. Ngokukodwa kwezinye iimeko apho iinkqubo ze-WIM ziyimfuneko kodwa ukuhamba kwetrafikhi kwisiza kuphezulu kakhulu, ukwakhiwa kweprojekthi kuhlala kunzima.
3) Ukutshatyalaliswa kwesakhiwo sendlela yokuqala, echaphazela ukubonakala.
I-4) Ukutshintsha ngokukhawuleza kwi-friction coefficients kunokubangela i-skidding phenomena, ngakumbi kwiimeko zemvula, ezinokukhokelela ngokulula kwiingozi.
5) Utshintsho kwindlela eyakhiwe ngayo lubangela ukungcangcazela kwesithuthi, okuchaphazela ukuchaneka kobunzima ukuya kuthi ga kwinqanaba elithile.
6) Ukwakhiwa ngokutsha kwekhonkrithi yesamente akunakuphunyezwa kwiindlela ezithile, ezifana neebhulorho eziphakamileyo.
7) Okwangoku, kwintsimi yezothutho zendlela, umkhwa uvela kumhlophe ukuya kumnyama (ukuguqula i-samente ye-samente kwi-asphalt pavement). Isisombululo samanje sisuka kumnyama ukuya kumhlophe, esingahambelani neemfuno ezifanelekileyo, kwaye iiyunithi zokwakha zihlala zixhathisa.
3. Isiqulatho seNkqubo yokuFakelo ephuculweyo
Injongo yesi sikimu kukusombulula intsilelo yepiezoelectric quartz weighing sensors ezingakwaziyo ukufakwa ngokuthe ngqo kwipavement ye asphalt ikhonkrithi.
Esi sikimu sibeka ngokuthe ngqo i-quartz ye-quartz ye-piezoelectric yokulinganisa i-sensor kwi-stid base layer, ukuphepha umbandela wokungahambelani kwexesha elide obangelwa ukufakwa ngokuthe ngqo kwesakhiwo senzwa eqinile kwi-pavement eguquguqukayo. Oku kwandisa kakhulu ubomi benkonzo kwaye kuqinisekisa ukuba ukuchaneka kobunzima akuchaphazeleki.
Ngaphezu koko, akukho mfuneko yokwenza isamente yolwakhiwo lwesamente kwipavumente ye-asphalt yokuqala, ukonga ixabiso elibalulekileyo leendleko zokwakha kunye nokunciphisa kakhulu ixesha lokwakha, ukubonelela ukuba nokwenzeka kokukhuthazwa okukhulu.
Umzobo wesi-2 ngumzobo oqingqiweyo wesakhiwo kunye ne-piezoelectric quartz yokulinganisa inzwa ebekwe kwisiseko esithambileyo.
(I-1-wheel, i-2-weight sensor, i-3-soft base layer, i-4-rigid base layer, i-5-flexible pavement, i-6-subsidence area, i-7-foam pad)
4. IiTekhnoloji eziPhambili:
1) Ukumba kwangaphambili kwesakhiwo sesiseko sokudala i-slot yokwakhiwa kwakhona, kunye nobunzulu be-slot ye-24-58 cm.
2) Ukulinganisa umzantsi we-slot kunye nokugalela izinto zokuzalisa. Umlinganiselo oqingqiweyo wesanti ye-quartz + i-stainless steel sand epoxy resin igalelwe ngaphantsi kwe-slot, izaliswe ngokulinganayo, kunye ne-filler ye-2-6 cm kunye nenqanaba.
3) Ukugalela isiseko esiqinileyo kunye nokufaka inzwa yokulinganisa. Thela isiseko esiqinileyo kwaye udibanise i-sensor yokulinganisa kuyo, usebenzisa i-foam pad (0.8-1.2 mm) ukuhlula amacala e-sensor yokulinganisa ukusuka kwisiseko esiqinileyo. Emva kokuba umaleko wesiseko oqinileyo uqina, sebenzisa i-grinder ukugaya inzwa yokulinganisa kunye nomgangatho oqinileyo wesiseko kwindiza efanayo. Umaleko wesiseko oqinileyo unokuba ngumaleko oqinileyo, ophakathi, okanye odibeneyo wesiseko.
4) Ukuchithwa komgangatho ophezulu. Sebenzisa izinto ezihambelanayo kunye ne-flexible base layer ukuze ugalele kwaye ugcwalise ubude obuseleyo be-slot. Ngethuba lenkqubo yokuthulula, sebenzisa umatshini omncinci wokudibanisa ukuba udibanise ngokukhawuleza, uqinisekisa umgangatho opheleleyo wendawo eyakhiwe ngokutsha kunye nezinye iindawo zendlela. Umaleko wesiseko oguquguqukayo ngumaleko we-asphalt ophakathi ococekileyo ophakathi.
I-5) Umlinganiselo wobunzima bomgangatho oqinileyo wesiseko kwi-flexible layer yi-20-40: 4-18.
