Asphalt coating: Technology kunye nokuFundiswa

Babulawa ngokusekelwe umxube bituminous indlela igqalwa enye Ipeyinti nenzuzo. Iluncedo, azibizi kwaye ngokubanzi ivumela ukuba iimpawu eziyimfuneko yokusebenza. Kakade ke, ukwenza ngaphandle iziphako, kodwa bakholisa ukuba kwenzeka kwiimeko ubugcisa non-ingqokelela. Kwelinye icala, ngobuchule amalungiselelo asphalt ukutyabeka inika amandla evelisa sezingeni eliphezulu kunye luthambe. Kulo mzekelo, kukho iindlela ezahlukeneyo kuphuhliso iindlela amaqonga, zibangela umahluko apho ukwakhiwa umxube nokupakisha technologies.

Ukudalwa umxube bituminous

technology asphalt Traditional inika phambi isixhobo kwindawo engundoqo ye yezimbiwa lokufaka kunye yokubopha. Iqela lokuqala izinto kuquka zesanti luhlalu. Ngaloo inkunkuma ukuze kufakwe luhlalu nesanti esetyenziswa sonke okanye batyumke.

Kwakhona kuxhomekeka iimfuno ukutyabeka kunye neemeko zayo zokusebenza zingasetyenziswa entle powder bezimbiwa. Ilungu somgquba ubume esisiseko idla Umatshini ngetha. Iimpawu okubangelwa wamkela asphalt eziphathekayo, sizimisele Indlela ekubunjweni umxube isiseko. Umahluko kwiindlela wokwenziwa isicombululo ngenxa Ipharamitha kumacandelwana esetyenzisiweyo. Umzekelo, amahlalutye okanye ilitye nakhandiweyo kungaba ukhethe kunye iqhezu ukususela-10 ukuya kuma-40 mm. Kunye itha ukuze viscosities ezahlukeneyo kunye ingxinano. Ezi kunye nezinye izinto ekugqibeleni kugqibe iimpawu ukutyabeka.

Imiyalelo zokuziswa iikhompawundi kwisiza

Oku ngokuyintloko kumiselwa uhlobo, inombolo kunye nomthamo izithuthi eziya kwenza phakathi kwehlabathi lonke unikezelo. Oku kukhetha ixhomekeke ububanzi bomsebenzi, umthamo umxube kunye izinga wesimeli elizayo. inkqubo yezothutho kubandakanya amanyathelo aliqela, kuquka zalishumi, izinto ngoko nangoko ithuthwa lilahle ukuba ukwamkelwa indawo yokulayisha. Ulondolozo othile, ingxubevange ebandayo kunye ashushu esetyenziselwa ukucoca umzimba dumper leyo sigqunywe ngumthunzi yokhuselo manzi okanye evalekayo. umxube oluxonxiweyo asphalt eziphathekayo oluthi luqokelelane, ihanjiswa kwindawo ebizwa ngokuba yi-Kocher. Le imoto nge thermos-ngabenzi, nasekuboneleleni inkqubo yokuthutha baxube kunye ubushushu nokwakheka. Ngokubhekiselele kwixesha zokuhamba, kwimeko kwimixube ashushu yemastic zixhomekeke iimpawu mixube kunye nezisombululo ngenxa nezithintelo ebandayo ixesha zokuhamba no.

umsebenzi wokulungiselela

Isiganeko esiphambili ngethuba ekulungiseleleni kokugqiba ukubeka mxube isixhobo test ngeso lenyama. Ubude imicwe ezinjalo ubuncinane 200 m, kwaye ububanzi ithathwa ngokungqinelana parameters lokudlula loo Paver. Ngokusekelwe kwiziphumo zovavanyo ingqokelela iteknoloji ukuqinisekisa umxube iresiphi ifanelekileyo, yaye ukuba kuyimfuneko, benze utshintsho kwinkqubo nokubekwa ukugangatheka yayo nobuchwepheshe.

asphalt Test ikhonkrithi uvavanywa iimpawu ezifana lobushushu, umgangatho kwisiseko itywina kunye nemeko t. D. Kuba njongo ubuchwepheshe yolawulo. In, iindlela ezithile ezingezo-otshabalalisayo iisampulu zomphakathi flash-uthatha, leyo ziphandwa ngakumbi kwiimeko elebhu. Ngomhla isiseko sesi sigqibo noochwephetsha banike iingcebiso kumenzi. Ukuba kuyimfuneko, umxube hlengiswe ukuya kwiimeko ezithile yokusebenza ngeso lenyama.

distribution umxube Technique

Phambi kokuba ezisasazwayo kwipleyiti ogqityiweyo wahlala phantsi emphethweni Paver wabeka amaplanga ngaphambili, ukuphakama ongqamana Ebubanzini nwebu kwaneliswa. Ukuze kuthintelwe ukusasazeka kwe umxube, esebenzisa ukutyibilika uhlobo formwork - kufuneka ukuhamba ngaphaya Paver. Ukuba isixhobo onjalo langoku, phambi kokuqala lonikezelo kwicala longitudinal kuyimfuneko ukulungisa umtya metal kufuneka ube malunga-20 m ubude. Ububanzi njengomqobo ngaphantsi kwe ukuphakama ukutyabeka kwakhiwa. Hi ndlela leyi, Ebubanzini asphalt enamathela phezu kumaqondo avareji ukusukela cm-5 ukuya kwali-10. Njengoko imivalo yesinyithi baqhube zicocwe ubeka Kuqukaniswa ubunzima. Ububanzi, owona ngokuqhelekileyo Zenziwe ulwabiwo nomxube egubungele yonke endleleni.

Ukuba isiseko lonikezelo phezu iziphene kumphezulu ziyazibhaqekela, kufuneka siqwalaselwe ngesandla. -Mbini Isenzo sokusebenzisa compactors avumela ngongoma-ukulungisa beentanda evuzayo, amaqhuma kunye nezinye nokungafezeki. Ngokuqhelekileyo, iziphene akhiwa kwi kwezahlulo band abutment ukuya isiqalelo abutment - bar metal efanayo. backfilled ngokwahlukeneyo ne amatshe awayekhotyokiswa. Ezi zoleko asphalt ukutyabeka benziwa umxube ngokufanayo bulk nangoko emva lonikezelo. Ngaphezu koko, izinto kwamaqondo eparticulate nto ingontsi kwi isiseko ukutyabeka isondo lula.

technology seal

inkqubo uphawu kufuneka kuqhutywa kunye ngomzi asphalt ukuba isasaze lo mxube. Kuqukaniswa mqengqeleki runs ngokuqhubekayo likhonkco. Kananjalo gladkovaltsovaya zinokusetyenziswa ezidityanisiweyo Ukusebenzisa umoya-bhasi. Amandla kunye nomthwalo ucinezelo asphalt maleko ashushu nabandayo zokusebenza ibalwa izikhombisi eziliqela. Ngokukodwa, ubuchule ithatha ingqalelo iimpawu lexinene lobushushu kunobukhulu.

Izixhobo asphalt enamathela umxube ashinyeneyo ashushu ezenziwa ngamatywina 0,99 ingumlingani. Pholisa umxube ukuba iqalise ngumba umthwalo we 0.96. coupling Cross imigca eDibanisa amalungiselelo aa Incopho esqwini kwendlela band omnye ngaphandle kokushiya emaweni. Ukuzalisekisa le meko phambi kokuphela zephetshana amalungiselelo zichetyiwe isixhobo ezizodwa a disc kwedayimani.

Ukulungiswa asphalt eziphathekayo yabahambi Guide

Ngaphambi kokuba lokwenza imisebenzi wokulungisa wenza uphando network. Ukuza kuthi ga ngoku, umphezulu leyo mayicocwe ngoncedo iibhrashi yendlela, ngoko izixhobo geodesic isetyenziswa ukuba ukujonga evenness na ukutyabeka. Kuxhomekeka kwisimo iziphene ezichongiweyo, imisebenzi ukulungiswa efanelekileyo. Ukuqinisekisa ngakumbi ukuba evenness ezi zoleko eliphawulwe ngokusebenzisa kwizikhondo indawo yokubeka. Bha nge kwinqanaba isicelo ukutyabeka wayesaphila. Beka endaweni umtya, apho ukuhla ubukhulu kubonisiwe, ithathwa njengokuba umgca elizayo ngombala ezinqamlezayo. Kwakhona, ukulungisa yabahambi asphalt angabonelela layers umthamo nokusebenza. Ngokuqhelekileyo, ezi ziganeko ziyasetyenziswa kwisixhobo ukutyabeka, ndinibumbela emaquleni. Ukuze wenze oku, ingasetyenziswa ifaka ezizodwa kwaye luqiniswe amacandelo eziphathekayo.

isaziso zokhuseleko

Nokuba ngaphambi kokuqalisa ekujoliswe inxenye yomsebenzi kufuneka zikhuselwe ngemiqondiso yendlela efanelekileyo. Ukusebenza abantu on-site kufuneka iovaroli, ngokwemigangatho emiselweyo. Ebusuku, lo ndawo kufuneka kwakhona kubonelelwa ukukhanyisa kunye izibane ezibengezelayo. amanyathelo Ezinye ukhuseleko zibonelelwa ukuba unyango kwezisombululo zeenkqubo. Ngoko, xa ukothula lo yenethiwekhi kunye nomxube abantu aziyi kuvunyelwa phakathi isithuthi kunye hopper ngezinto. Ngethuba ubeka Kuqukaniswa iindlela asphalt enamathela kufuneka bakhululeke izinto zangaphandle kunye nabasebenzi. Emva kokugqitywa imisebenzi lonke uluhlu, izixhobo kunye nezinto kufuneka zisuswe ukutyabeka kwaye zisiwe kwindawo yokugcina efanelekileyo.

ngeso lenyama control Quality

Uvavanyo lwe-inshorensi amalungiselelo umgangatho wenziwa ngoncedo izixhobo ezikhethekileyo. Ngokukodwa, sebenzisa izixhobo automated ukukala for yokulinganisa, kwakunye nezixhobo ezizodwa evumela umboniso ezihlangeneyo output data eqhutywa. Phakathi kwiimpawu zixhaphakileyo, nto leyo kuqikelelwa ngokusekelwe "umsebenzi" Ipeyinti asphalt, kukho ukungqinelana parameters uyilo balo babulingana nobubanzi, flatness umaleko, ukuthambeka, iqondo lobushushu kunye nomgangatho beentanda phakathi ubumba.

isiphelo

NemiSebenzi, engamzondi asphalt i iseti amanyathelo technical. Ngoko ke kubaluleke kakhulu ukusuka kwindawo umbono yokutshata endleleni ezikumgangatho ophezulu kufuneka izibalo ekuqaleni kuyilo sebhodi. Nokuba kunye nokubekwa ukhuthele nokwaleka uphawu ayiyi kuba nako ukwenza umsebenzi wabo ukuba umxube engafanelekanga kukhethwa. Nangona basic ukutyabeka technology asphalt kubandakanya ukusetyenziswa iseti eqhelekileyo yeekhomponenti kwanasekundilungiseleleni isisombululo ukulungiselela ufakelo parameters zabo ziyahluka. Ngoko ngokubekwa imixube kwetyala kwenziwa ezinika ukuqonda ngakumbi iimpawu nenzuzo ye ukutyabeka ukuba site ethile. Kwaye inoxanduva umgangatho wendlela idlula ngqo kwiqela yokusebenza ukuba isasaze kwaye Oluma ubunzima asphalt eziphathekayo.
