1. Background Technology
Parizvino, masisitimu eWIM akavakirwa papiezoelectric quartz anoyera masensa anoshandiswa zvakanyanya mumapurojekiti akadai sekutarisa kuwandisa kwemabhiriji nema culverts, kusiri kwesaiti kuwandisa kwekuita kwemotokari dzinotakura zvinhu, uye tekinoroji overload control. Nekudaro, kuve nechokwadi chechokwadi uye hupenyu hwesevhisi, mapurojekiti akadai anoda simende kongiri pavement kuvakazve yepiezoelectric quartz inorema sensor yekumisikidza nzvimbo ine yazvino tekinoroji level. Asi mune dzimwe nzvimbo dzekushandisa, dzakadai semabhiriji edhizaini kana migwagwa mikuru yemumaguta ine inorema traffic traffic (apo nguva yekurapa simende yakarebesa, zvichiita kuti kuvharwa kwemigwagwa kwenguva refu kuve kwakaoma), mapurojekiti akadaro akaoma kuita.
Chikonzero icho piezoelectric quartz inoyera sensors haigone kuiswa zvakananga painochinjika pavement ndeiyi: Sezvinoratidzwa muMufananidzo 1, kana vhiri (kunyanya pasi pemutoro unorema) richifamba munzira inochinjika, nzvimbo yemugwagwa ichava neyakakura zvishoma. Nekudaro, kana uchisvika kune yakaoma piezoelectric quartz inorema sensor nzvimbo, iyo subsidence maitiro eiyo sensor uye iyo pavement interface nzvimbo yakasiyana. Uyezve, iyo yakaomesesa yekuyera sensor haina yakatwasuka inonamatira, zvichiita kuti inorema sensor ikurumidze kutyora uye kuparadzaniswa kubva pamugwagwa.
(1-vhiri, 2-inoyeresa sensor, 3-yakapfava base layer, 4-yakasimba base layer, 5-inochinjika pavement, 6-subsidence nzvimbo, 7-furo pad)
Nekuda kweakasiyana hunhu hwekudzika uye akasiyana pavement friction coefficients, mota dzinopfuura nepakati pepiezoelectric quartz inorema sensor inosangana nekudengenyeka kwakanyanya, zvichikanganisa zvakanyanya huremu hwese. Mushure menguva refu yekutsikirirwa kwemotokari, saiti yacho inokanganisa kukuvara uye kuputika, zvichitungamira kukuvadzwa kwe sensor.
2. Ikozvino Solution Mundima Iyi: Cement Concrete Pavement Reconstruction
Nekuda kwedambudziko repiezoelectric quartz inoyera ma sensors ekutadza kuisirwa zvakananga pane asphalt pavement, chiyero chakatekeshera chakagamuchirwa muindasitiri iyi simende kongiri yekuvakazve kwepiezoelectric quartz inorema sensor yekuisa nzvimbo. Iyo yakawanda yekuvaka patsva kureba ndeye 6-24 metres, nehupamhi hwakaenzana nehupamhi hwemugwagwa.
Kunyangwe iyo simende kongiri yekuvaka pavement ichisangana nezvinodiwa zvesimba zvekuisa piezoelectric quartz inoyera masensa uye inovimbisa hupenyu hwesevhisi, nyaya dzinoverengeka dzinomanikidza zvakanyanya kusimudzirwa kwayo kwakapararira, kunyanya:
1) Simende yakawedzera kuomesera kuvaka patsva kwegwagwa rekutanga kunoda mari yakawanda yekuvaka.
2) Cement kongiri kuvaka zvakare kunoda nguva yakareba kwazvo yekuvaka. Nguva yekurapa simende pavement chete inoda mazuva makumi maviri nemasere (chinodikanwa chinodiwa), pasina mubvunzo ichikonzera kukanganisa kukuru kusangano remotokari. Kunyanya mune dzimwe nguva apo WIM masisitimu anodiwa asi pa-saiti traffic inoyerera yakakwira zvakanyanya, kuvaka chirongwa kunowanzo kuoma.
3) Kuparadzwa kwechimiro chepakutanga chemugwagwa, kukanganisa chitarisiko.
4) Kamwe-kamwe kushanduka kwe friction coefficients kunogona kukonzera skidding phenomena, kunyanya mukunaya kwemvura, izvo zvinogona kutungamirira njodzi nyore nyore.
5) Shanduko muchimiro chemugwagwa dzinokonzeresa kuzununguka kwemotokari, izvo zvinokanganisa kuyera kurongeka kune imwe nhanho.
6) Kuvakazve kongiri yesimende hakugone kuitwa pane mamwe migwagwa, senge mabhiriji akakwirira.
7) Parizvino, mumunda we traffic traffic, maitiro ari kubva kuchena kusvika kune dema (kushandura simende pavement kuenda asphalt pavement). Mushonga wezvino uno unobva kune dema kusvika kuchena, izvo zvisingaenderani nezvinodiwa zvakakodzera, uye zvikwata zvekuvaka zvinowanzoshorwa.
3. Yakavandudzwa yekuisa Scheme Content
Chinangwa chechirongwa ichi ndechekugadzirisa kushomeka kwepiezoelectric quartz inoyera sensors isingakwanise kuiswa yakananga pane asphalt kongiri pavement.
Ichi chirongwa chinoisa zvakananga piezoelectric quartz inoyera sensor pane yakaomesesa base layer, ichidzivirira iyo yakareba isingaenderane nyaya inokonzerwa nekumisikidzwa kwakananga kweiyo rigid sensor chimiro mune inochinjika pavement. Izvi zvinowedzera zvakanyanya hupenyu hwebasa uye hunova nechokwadi chekuti kuyera kurongeka hakukanganisi.
Uyezve, hapana chikonzero chekuita simende kongiri kuvaka pavement payakatanga asphalt pavement, kuchengetedza mari yakawanda yekuvaka uye kupfupisa zvakanyanya nguva yekuvaka, zvichipa mukana wekusimudzira kwakakura.
Mufananidzo 2 idhizaini yechimiro chechimiro chine piezoelectric quartz inoyera sensor yakaiswa pane yakapfava base layer.
(1-vhiri, 2-inoyeresa sensor, 3-yakapfava base layer, 4-yakasimba base layer, 5-inochinjika pavement, 6-subsidence nzvimbo, 7-furo pad)
4. Key Technologies:
1) Pretreatment kucherwa kwechigadziko chimiro kuti ugadzire nzvimbo yekuvakazve, ine slot yakadzika ye24-58 cm.
2) Kukwirisa pasi peiyo slot uye nekudurura zvinhu zvekuzadza. Chiyero chakagadziriswa chejecha re quartz + simbi isina tsvina yejecha epoxy resin inodururwa muzasi pe slot, yakaenzana yakazadzwa, ine kuzadza kwakadzika kwe 2-6 cm uye yakaenzana.
3) Kudururira yakaomesesa base layer uye nekuisa inoyera sensor. Dururira iyo yakaomeswa base layer uye nyudza inoyera sensor mukati mayo, uchishandisa furo pad (0.8-1.2 mm) kuparadzanisa mativi ehuremu sensor kubva kune yakaoma base layer. Mushure mekuoma kwegadziko layer yasimba, shandisa grinder kukuya chinoyera chinoyera uye chakaomarara base layer kune imwe ndege. Iyo yakaoma base layer inogona kuve yakaoma, semi-yakaomarara, kana composite base layer.
4) Kukanda kwepamusoro pedenga. Shandisa zvinhu zvinoenderana neinochinjika base layer kudira nekuzadza hurefu hwasara hweiyo slot. Panguva yekudurura, shandisa kamuchina kadiki kadiki kubatanidza zvishoma nezvishoma, kuve nechokwadi cheyero yese yenzvimbo yakavakwa patsva nedzimwe nzvimbo dzemugwagwa. Iyo inochinjika base layer ndeye yepakati-yakanaka granular asphalt pamusoro layer.
5) Ukobvu chiyero cheyakaomarara base layer kune inochinjika base layer ndeye 20-40:4-18.
