Pane mutsauko mudiki muchimiro chekushanda kweasphalt gravel synchronous yekuisa chisimbiso marori pamusika, asi pachave nemimwe misiyano muchimiro chemuchina. Iyo asphalt gravel synchronous yekuisa chisimbiso marori anonyanya kushandiswa kune nzvimbo dzemigwagwa, dhizaini redhiza rekudzivirira mvura, uye pasi pekuisa chisimbiso. Gravel sealing process. Mudziyo uyu unoona kuwiriraniswa kwekupararira kweasphalt binder uye kupararira kwematombo, kuitira kuti asphalt binder nematombo zvive nekusangana kwakazara kwepamusoro munguva pfupi uye kuwana yakanyanya kunamatira pakati pawo. Iyo midziyo inonyanya kukodzera kuparadzira asphalt binders inoda kushandiswa kweasphalt yakagadziridzwa kana rubber asphalt. Basa rose nderekupedzisa asphalt kupararira uye matombo achipararira panguva imwe chete.
Iyo asphalt gravel synchronous sealing rori inotora asphalt kubva mutangi reasphalt kuburikidza nepombi yeasphalt, uye yobva yaipfapfaidza kunze kubva kune asphalt yekuparadzira tsvimbo kuburikidza neakatevedzana mavharuvhu uye mapaipi; panguva imwecheteyo, iyo gravel yekuparadzira system inoshandawo synchronously. Mutakuri anoisa aggregate mubhini rekubatanidza rori yekuvharisa pachine nguva. Panguva yekushanda, iyo hydraulic mota inotyaira mabhandi ekutakura (maviri) kutumira matombo kune inopararira hopper. Iyo pneumatic system inodzora silinda kuti ivhure gonhi rezvinhu, uye ma roller anopararira anofambiswa ne hydraulic mota. Pasi pedhiraivha, madhiri ekuyerera anotsemuka uye anokandwa mugedhi rekugezera. Iro gravel yakawaridzwa zvakaenzana pane asphalt pavement kuburikidza negwara rekutungamira, nekudaro kupedzisa synchronous yekuisa chisimbiso cheasphalt gravel.
Iyo hydraulic pombi inotyaira iyo hydraulic mota kuti itenderere, iyo inotyaira bhandi rekutakura kuti rimhanye, kutakura matombo kuenda kudombo rekuparadzira system. Mukova wezvinhu unovhurwa kuburikidza nepneumatic system, uye girafu rinopararira pasi pechiito chehuremu hwematombo uye kutenderera kwekuparadzira roller. Kune maviri ezvinyorwa level sensors mune yekuparadzira system. Iyo yemagetsi control system inoshandisa aya ma sensors maviri kutarisa huwandu hwezvinhu mune yekubatsira hopper uye inodzora kana maviri solenoid mavharuvhu ane simba, nokudaro achidzora kana mota inotakura iri kumhanya uye kuona iyo aggregate kufambisa. Real-time control. Munguva yedebugging, kumhanya kwemota yekudyisa inogadziriswa nekudzora saizi yekuvhura maviri evhavhavhavha. Kazhinji, kumhanya kwekutanga kwemota kunoiswa kune anenge 260r · min-1. Iko kumhanya kwemota kunogona kugadziridzwa zvinoenderana nemamiriro chaiwo ekushanda kuti asangane nezvinodiwa zvekuvaka.
Nheyo yayo inopindirana nemusimboti wegravel inoparadzira hydraulic system. Iko kumhanya kweiyo inoparadzira mota inodzorwa nekugadzirisa throttle valve, uye kutanga uye kumira kwekupararira roller kunoonekwa nekudzora kana solenoid valve ine simba kana kwete.

Basa rakakosha re slurry sealing tekinoroji mukugadzirisa migwagwa
Sezvo kugadzirisa kwemigwagwa kunowedzera kukosha, marori anovhara slurry anoita basa guru mukugadzirisa migwagwa. Mukugadzirisa mugwagwa mukuru, chinhu chikuru che slurry sealing tekinoroji is emulsified asphalt, uye mabasa ayo makuru ndeaya: Izvi zvinotevera zvinhu.
Chekutanga, iyo slurry seal tekinoroji yekuchengetedza chiteshi inovandudza kusapinda kwemvura basa remugwagwa. Iri basa haripatsanurike kubva kune akasiyana kuumbwa uye diki diki saizi yemusanganiswa weslurry. Aya maficha anoitendera kuti igadzire nzvimbo yakaoma mushure mekugadzira. Zvishandiso zvine saizi diki zvinogona kuvandudza dhigirii rekubatanidza yeyakatanga nzira kusvika pamwero mukuru uye kudzivirira zvirinani kunaya kana chando kubva pakupinda mukati mepavement base layer. Muchidimbu, nekuti zvigadzirwa zve slurry sealing tekinoroji hazvina kungoita diki diki saizi asiwo zvine imwe gradation, kugadzikana kweiyo pavement base layer uye ivhu dhizaini inovandudzwa zvakanyanya, uye iyo permeability coefficient yepavement inoderedzwa.
Chechipiri, chisimbiso che slurry chinowedzera kukwesha kwepamusoro pemugwagwa uye inovandudza anti-skid effect yemugwagwa. Chinhu chakakosha chekugadzira slurry musanganiswa ndeyekufanana, saka ukobvu hweasphalt hunofanira kunge hwakafanana uye zvinhu zvakakodzera zvinofanirwa kushandiswa kudzivirira yakawandisa pavement ukobvu. Kuita uku chinhu chakakosha pakuona kunaka kwenzira, kuitira kuti isatambudzike nekutsvedza kwakanyanya uye kuraswa kwemafuta panguva yekuvharira chisimbiso, izvo zvinozotungamira mukudzikira kwekupokana pamusoro pemugwagwa uye kuita kuti mugwagwa utsvedze. uye isina kukodzera kushandiswa. Kusiyana neizvi, migwagwa mizhinji inochengetedzwa nehunyanzvi hwekuisa chisimbiso tekinoroji ine nzvimbo dzakakasharara dzine hukasha hwakakodzera, uye friction coefficient inowedzera zvakakodzera uye inoramba iri mukati meiyo yakanaka inoshanda. Iyi ndiyo kiyi yekuvimbisa kunaka kwekufambisa, nekudaro kuvandudza zvakanyanya kunaka kwekufambisa. kuvandudza kuchengetedzwa kwekushanda kwemigwagwa.
Chechitatu, slurry sealing layer inozadza nzira yemugwagwa zviri nani, ichiwedzera kutsvedzerera kwemugwagwa uye kuita kuti zvive nyore kutyaira. Sezvo musanganiswa we slurry wakaumbwa mushure mekunge hunyoro hwakakwana hwabatanidzwa, hune humwe hunyoro. Izvi hazvingovimbisi kuyerera kwayo kwakanaka, asi zvakare inotora rimwe basa mukuzadza mitswe yakanaka muasphalt pavement. Kana mitswe yazadzwa, haichakanganisa kutsvedzerera kwenzira. Migwagwa mikuru yepakutanga inowanzotambura nekusapura zviyo uye nzira isina kuenzana. Slurry sealing tekinoroji yakavandudza matambudziko aya kusvika pamwero mukuru, kuve nechokwadi kutsetseka kwenzira, kuvandudza kunaka kwenzira, uye kuderedza kuoma kwekutyaira.
Chechina, tekinoroji yekuisa chisimbiso tekinoroji inovandudza kupfeka kuramba kwemugwagwa, inoderedza kukuvadzwa kwemugwagwa, uye inowedzera hupenyu hwebasa remugwagwa. Chinhu chikuru chinoshandiswa mu slurry chisimbiso is emulsified asphalt. Kubatsira kweasphalt emulsified kunonyanya kuratidzwa mukunamatira kwayo kwakakwirira kune acid uye alkaline mineral materials, iyo inosimudzira zvikuru kubatana pakati pe slurry uye nzira yemugwagwa.
Chechishanu, slurry chisimbiso chinogona kuchengetedza chitarisiko chemugwagwa. Munguva yekushandiswa kwenguva refu kwemigwagwa mikuru, nzvimbo yacho ichapfekwa, ichena, yakwegura uye yakaoma, uye zvimwe zviitiko zvinokanganisa chitarisiko. Izvi zviitiko zvichavandudzwa zvakanyanya mushure mekugadzirisa ne slurry sealing tekinoroji.

Chii chinoita kuti slurry sealing tekinoroji ine chekuita nekugadzirisa migwagwa?
Pamusana pekubatanidzwa kwechimwe chikamu chemvura mumusanganiswa wekuvhara slurry, zviri nyore kubuda mumhepo. Mushure mekunge mvura yaputika, inooma uye yakaoma. Nokudaro, mushure mokunge slurry yakaumbwa, haingotaridzi zvakanyanya kufanana nekongiri yeasphalt yakatsetseka, asi haikanganisi kuonekwa kwemugwagwa. Iyo ine zvakare yakafanana tekinoroji zvimiro seyakakwenenzverwa kongiri maererano nekupfeka kuramba, anti-skid, kudzivirira mvura, uye kutsetseka. Slurry seal tekinoroji inoshandiswa mukugadzirisa mugwagwa mukuru nekuda kwehunyanzvi hwayo hwekuvaka, nguva pfupi yekuvaka, mutengo wakaderera, mhando yepamusoro, kushandiswa kwakakura, kuchinjika kwakasimba, etc. I asphalt ine hupfumi uye hunyanzvi hwepamusoro. Pavement kugadzirisa tekinoroji yakakodzera kushandiswa uye kusimudzirwa.
Mukugadzirisa mugwagwa mukuru, chinhu chikuru che slurry seal tekinoroji is emulsified asphalt, uye mabasa ayo makuru anoratidzwa mune zvinotevera zvinhu.
Kutanga, slurry sealing tekinoroji inovandudza basa rekudzivirira mvura remugwagwa. Iri basa haripatsanurike kubva kune akasiyana kuumbwa uye diki diki saizi yemusanganiswa weslurry. Aya maficha anoitendera kuti igadzire nzvimbo yakaoma mushure mekugadzira. Zvishandiso zvine saizi diki zvinogona kuvandudza dhigirii rekubatanidza yenzira yekutanga kusvika pamwero mukuru uye kudzivirira zvirinani kunaya kana sinou kupinda mukati menzira.
Chechipiri, chisimbiso che slurry chinowedzera kukwesha kwepamusoro pemugwagwa uye inovandudza anti-skid effect yemugwagwa. Chinhu chakakosha chekugadzira musanganiswa we slurry kufanana, saka ukobvu hweasphalt hwakafanana uye zvinhu zvakakodzera zvinoshandiswa kudzivirira kuwanda kwemugwagwa.
