Kuchengetedza kwekudzivirira kunogona kudzivirira zvirwere zvepavement uye chave chinhu chakakosha chekugadzirisa migwagwa. Inoderedza kuderera kwekuita kwepavement, inowedzera hupenyu hwebasa repavement, inovandudza kushanda kwesevhisi yenzira, uye inochengetedza mari yekuchengetedza nekugadzirisa. Inowanzoshandiswa kumamiriro ezvinhu asati aitika. Pavement yakakuvadzwa kana ine chirwere chidiki chete.
Kubva pakuona kwekudzivirira kuchengetedza kweasphalt pavement, kana ichienzaniswa nemamwe matekinoroji, synchronous gravel sealing tekinoroji haiise pamberi pepamusoro zvinodiwa zvemamiriro ekuvaka. Zvisinei, kuitira kuti uvandudze kushanda kwekugadzirisa, zvakakosha kupa kutamba kwakazara kune zvakanakira iyi teknolojia itsva. Zvakanakira zvichiri kuda mamwe mamiriro. Chokutanga pane zvose, zvakakosha kuongorora kukanganisa kwepamusoro pemugwagwa uye kujekesa nyaya dzinokosha dzichagadziriswa; nyatso funga nezvemhando yemhando yeasphalt binder uye aggregate, senge kunyorova kwayo, kunamatira, kupfeka kuramba, kumanikidza kuramba, nezvimwe; Ita mabasa epaving mukati mechikamu chinotenderwa nehunyanzvi hwekuita; sarudza zvinhu nenzira kwayo uye zvine musoro, sarudza magiredhi, uye shandisa michina yekugadzira nemazvo. Synchronous gravel sealing kuvaka tekinoroji:

(1) Zvivako zvinogara zvichishandiswa: Zvivako zvegiredhi zviya zvinogara zvichishandiswa, uye pane zvakaomesesa zvinodikanwa pakukura kwebwe rinoshandiswa kuvharisa chisimbiso, kureva kuti, matombo akaenzana saizi akakodzera. Tichifunga nezvekuoma kwekugadzirwa kwematombo uye zvakasiyana-siyana zvinodiwa zvekudzivirira-skid kuita kwepamusoro pemugwagwa, kune magiredhi mashanu, anosanganisira 2 kusvika 4mm, 4 kusvika 6mm, 6 kusvika 10mm, 8 kusvika 12mm, uye 10 kusvika 14mm. Iyo inonyanya kushandiswa particle size range ndeye 4 kusvika 6mm. .
(2) Sarudza iyo particle size yedombo zvichienderana nemugwagwa wepamusoro kutsvedzerera uye anti-skid kuita zvinodiwa. Kazhinji, gravel seal layer inogona kushandiswa kudzivirira mugwagwa. Kana kutsvedzerera kwemugwagwa kuri kushoma, matombo ehukuru hwakakodzera hunogona kushandiswa sechisimbiso chepasi chekuenzanisa, uye ipapo chisimbiso chepamusoro chinogona kuiswa. Kana iyo gravel seal layer ichishandiswa seyepasi-giredhi nzira huru, inofanirwa kuve 2 kana 3 akaturikidzana. Iwo madiki saizi ematombo mune imwe neimwe layer anofanirwa kufananidzwa nemumwe kuti abudise embedding mhedzisiro. Kazhinji, musimboti wekukora pazasi uye wakatsetseka kumusoro unoteverwa;
(3) Usati waiswa chisimbiso, nzira yekutanga inofanira kucheneswa. Munguva yekushanda, nhamba yakakwana yerabha-yakaneta migwagwa rollers inofanirwa kuve nechokwadi kuitira kuti kukungurutsa uye kumisa maitiro kunogona kupedzwa munguva isati asphalt tembiricha yadonha kana mushure mekunge emulsified asphalt yabviswa. Uye zvakare, inogona kuvhurwa kune traffic mushure mekuiswa chisimbiso, asi kumhanya kwemotokari kunofanirwa kudzikiswa padanho rekutanga, uye traffic inogona kuvhurwa zvizere mushure memaawa maviri kudzivirira kuputika kwematombo kunokonzerwa nekukurumidza kutyaira;
(4) Paunenge uchishandisa asphalt yakagadziridzwa sebhainda, kuitira kuti uve nechokwadi chekufanana uye kuenzana kwefirimu yeasphalt yakagadzirwa nemhute yekupfapfaidza, kutonhora kweasphalt kunofanira kunge kuri pakati pe160 ° C kusvika 170 ° C;
(5) Kureba kweinjector nozzle yeiyo synchronous gravel yekuvharisa rori kwakasiyana, uye ukobvu hwefirimu reasphalt rakagadzirwa huchasiyana (nekuti kupindirana kweasphalt yakaita sefan-shape asphalt yakapfapfaidzwa nemhuno yega yega yakasiyana), ukobvu. yefirimu yeasphalt inogona kuitwa kuti isangane nezvinodiwa nekugadzirisa kureba kwemuromo. Require;
(6) Rori inonamira matombo inofanira kutyaira yakaenzana nekumhanya kwakakodzera. Pasi pechinhu ichi, chiyero chekupararira kwebwe uye chinhu chinosungirirwa chinofanira kufanana;
(7) Mamiriro ekushandiswa kweiyo gravel seal layer seyepamusoro kana kupfeka layer ndeyekuti kutsvedzerera uye kusimba kweiyo nzira yekutanga inosangana nezvinodiwa.
