Road Milling: Chii? Chinoshanda sei?

Kugaya migwagwa kunogona kunzi kugayo, asi kunopfuura kungogadzira migwagwa. Nhasi, tichanyura munyika yekugadzira migwagwa uye tidzidze ruzivo rwakadzama senge muchina, mabhenefiti, nezvimwe.

Chii chinonzi Road Milling/Pavement Milling?

Pavement milling, inonziwo asphalt milling, kutonhora kugaya, kana kutonhora planing, inzira yekubvisa chikamu chenzvimbo yakarongwa, inovhara migwagwa, madhiraivha, mabhiriji, kana nzvimbo dzekupaka. Kutenda kune asphalt milling, kureba kwemugwagwa hakuzowedzeri mushure mekuisa pasi asphalt nyowani uye zvese zviripo zvinokuvadza zvimiro zvinogona kugadziriswa. Zvakare, iyo yekare asphalt yakabviswa inogona kudzokororwa seyakaunganidzwa kune mamwe mapurojekiti epavhu. Kuti uwane zvikonzero zvakawanda, ingoverenga!

Road Milling Zvinangwa

Pane zvikonzero zvakawanda zvekusarudza nzira yekugadzira mugwagwa. Chimwe chezvikonzero zvakakosha ndechekudzokorora. Sezvambotaurwa pamusoro, asphalt yekare inogona kushandiswazve semuunganidzwa wemapurojekiti matsva epavement. Recycled asphalt, inozivikanwawo se reclaimed asphalt pavement (RAP), inosanganisa tara yakare yakagayiwa kana kupwanywa uye asphalt itsva. Kushandisa asphalt yakadzokororwa pachinzvimbo cheasphalt nyowani yemugwagwa kunoderedza huwandu hukuru hwemarara, kuchengetedza mari yakawanda kumabhizinesi, uye kunoderedza kukanganisa kwakashata pane zvakatipoteredza.

Kunze kwekudzokorodza, kugaya migwagwa kunogona zvakare kuwedzera kunaka kwenzvimbo dzemigwagwa uye kuwedzera hupenyu hwesevhisi, nekudaro kuvandudza ruzivo rwekutyaira. Nyaya dzakanangana dzinogona kugadziriswa kugayo nekugaya kusaenzana, kukuvadzwa, kukora, kupenga, uye kubuda ropa. Kukuvadzwa kwemugwagwa kunowanzokonzerwa nenjodzi dzemotokari kana moto. Rutting (Rutting) zvinoreva mitsetse inokonzerwa nekufamba kwemavhiri semarori akatakura zvikuru. Raveling zvinoreva muunganidzwa wakapatsanurwa kubva kune mumwe nemumwe. Kana asphalt ichikwira kumugwagwa, kubuda ropa kunoitika.

Uyezve, kugaya migwagwa kwakanakira kugadzira rumble strips.

Mhando dzeMugwagwa Milling

Kune marudzi matatu makuru ekugadzira mugwagwa wekubata nemhando dzakasiyana dzemamiriro. Midziyo yakakosha uye hunyanzvi hunodiwa kune yega yega nzira yekugaya zvinoenderana.

Fine-Milling

Fine milling inoshandiswa kugadzirisa denga repavement uye kugadzirisa kukuvara kwepamusoro. Maitiro acho ndeaya anotevera: bvisa yakakuvadzwa pamusoro asphalt, gadzirisa iyo yekutanga kukuvadzwa, uye vhara pamusoro neasphalt nyowani. Zvadaro, zvinyoro uye kuenzanisa pamusoro peiyo asphalt itsva.

Kuronga

Yakasiyana nekugaya kwakanaka, kuronga kunowanzo shandiswa mukugadziridza zvivakwa zvakakura senzira huru dzemigwagwa. Chinangwa chayo ndechekuvaka nzvimbo yakaenzana yekugara, maindasitiri, motokari, kana zvekutengesa zvikumbiro. Maitiro ekuronga anosanganisira kubvisa iyo yese yakakanganisika pavement pachinzvimbo chepamusoro chete, uchishandisa zvidimbu zvakabviswa kugadzira aggregate, uye kushandisa aggregate kune itsva nzira.

Micro-Milling

Micro milling, sezvinoratidzwa nezita racho, inongobvisa yakatetepa (inenge inch imwe kana zvishoma) yeasphalt pachinzvimbo chepamusoro pese kana pavement. Chinangwa chikuru che micro milling ndechekugadzirisa kwete kugadzirisa. Iyi inzira yakanakisa yekudzivirira mugwagwa kubva pakuipa. Chigubhu chinotenderera chinoshandiswa mukugaya, nemazino akawanda ekucheka ane carbide-tipped, aka mugwagwa wekugaya mazino, akaiswa padhiramu. Aya mazino ekugaya mugwagwa akarongwa mumitsara kuti agadzire nzvimbo yakatsetseka. Zvisineyi, kusiyana nemadhiramu ekugayo, micro milling inongogadzira pasi kusvika pakadzika pasi, asi ichigadzirisa matambudziko mamwe chete emumugwagwa.

Maitiro & Machina

Muchina wekugaya unotonhora unoita pavement milling, inodaidzwawo kuti cold planer, kunyanya inosanganisira dhiramu rekugaya neconveyor system.

Sezvataurwa pamusoro apa, dhiramu rekugaya rinoshandiswa kubvisa uye kukuya asphalt pamusoro nekutenderera. Iyo dhiramu yekugaya inotenderera ichienda kune yakatarisana neyainofamba nemuchina, uye kumhanya kwakadzikira. Iyo ine mitsetse yezvibatiso zvemidziyo, yakabata carbide-tipped mazino ekucheka, akamugwagwa unogaya mazino. Ndiwo mazino ekucheka anocheka nzvimbo yeasphalt. Nekuda kweizvozvo, mazino ekucheka uye zvibatiso zvemidziyo zviri nyore kupera uye zvinoda kutsiviwa kana zvatyoka. Nguva dzepakati dzinotemerwa nechigayo, kubva pamaawa kusvika kumazuva. Nhamba yemazino ekugaya mugwagwa inokanganisa zvakananga mhedzisiro yekugaya. Kunyanya, kutsetseka.

Panguva yekushanda, asphalt yakabviswa inowira kubva kune conveyor. Zvadaro, conveyor system inotamisa asphalt yakare yakagayiwa kuenda kurori inotyairwa nemunhu iyo iri pamberi zvishoma pane inotonhora planer.

Pamusoro pezvo, kugaya kunoita kupisa neguruva, saka mvura inoshandiswa kutonhodza dhiramu uye kuderedza guruva.

Mushure mokunge nzvimbo yeasphalt yakagayiwa kusvika pahupamhi hunodiwa uye kudzika, inoda kucheneswa. Zvadaro, asphalt itsva ichaiswa zvakaenzana kuti ive nechokwadi chehurefu hwakafanana. Iyo asphalt yakabviswa ichashandiswa zvakare kumapurojekiti matsva epavement.

Benefits

Sei tichisarudza kugaya asphalt senzira yakakosha yekugadzirisa nzira? Tataura pamusoro. Zvino, ngatikurukurei zvimwe zvezvikonzero zvakakosha.

Affordable uye Economic Efficiency

Nekuda kwekushandisa yakadzokororwa kana kudzoreredzwa asphalt, mutengo wakaderera chero ipi nzira yekugaya yaunosarudza. Makondirakiti ekugadzirisa migwagwa anowanzo chengetedza asphalt yakadzokororwa kubva kumapurojekiti epavement apfuura. Nenzira iyi chete, ivo vanokwanisa kuderedza mitengo uye vachiri kupa basa rakakura kune vatengi.

Kuchengetedza kwezvakatipoteredza

Yakabviswa asphalt inogona kusanganiswa nezvimwe zvinhu uye kushandiswazve, nekudaro haizotumirwe kunoraswa. Chaizvoizvo, mazhinji emigwagwa uye mapurojekiti ekugadzirisa anoshandisa asphalt yakadzokororwa.

Hapana Drainage & Pavement Height Issues

Mishonga mitsva yepasi inogona kukwidza kureba kwepavement pamwe nekukonzera nyaya dzemvura. Nekugaya asphalt, hapana chikonzero chekuwedzera akawanda matsva maturu pamusoro uye hapazove nematambudziko ezvimiro senge kukanganiswa kwemvura.
