Road Milling: Ndi Chiyani? Kodi Zimagwira Ntchito Motani?

Kupera mumsewu kungaoneke ngati mphero, koma sikutanthauza kungokonza misewu. Lero, tilowa m'dziko la mphero ndikuphunzira zambiri monga makina, mapindu, ndi zina zambiri.

Kodi Kugaya Msewu/Pavement Milling ndi Chiyani?

Pavement mphero, yomwe imatchedwanso kuti mphero ya asphalt, mphero yozizira, kapena kuzizira kozizira, ndi njira yochotsa mbali yoyalidwa, misewu, ma driveways, milatho, kapena malo oimikapo magalimoto. Chifukwa cha mphero ya asphalt, kutalika kwa msewu sikungawonjezeke pambuyo poyika phula latsopano ndipo zowonongeka zonse zomwe zilipo zitha kukhazikitsidwa. Komanso, asphalt wakale wochotsedwayo atha kugwiritsiridwanso ntchito ngati ophatikiza pama projekiti ena apamisewu. Pazifukwa zambiri, ingowerengani!

Zolinga Zogaya Njira

Pali zifukwa zingapo zosankha njira yophera msewu. Chimodzi mwa zifukwa zofunika kwambiri ndi kubwezeretsanso. Monga tafotokozera pamwambapa, asphalt yakale imatha kubwezeretsedwanso ngati yophatikiza pama projekiti atsopano apamisewu. Recycled asphalt, yomwe imadziwikanso kuti reclaimed asphalt pavement (RAP), imaphatikiza phula lakale lomwe lagayidwa kapena kuphwanyidwa ndi phula watsopano. Kugwiritsa ntchito phula wobwezerezedwanso m'malo mwa phula watsopano popondapo kumachepetsa zinyalala zambiri, kumapulumutsa ndalama zamabizinesi, komanso kumachepetsa kuwononga chilengedwe.

Kupatula kukonzanso zinthu, mphero zimathanso kupititsa patsogolo mawonekedwe amisewu ndikuwonjezera moyo wautumiki, motero kumapangitsa kuyendetsa bwino. Zinthu zomwe mphero imatha kuthetsa ndi kusalinganika, kuwonongeka, kudzipiritsa, kunjenjemera, komanso kutuluka magazi. Kuwonongeka kwa msewu nthawi zambiri kumachitika chifukwa cha ngozi zagalimoto kapena moto. Rutting amatanthawuza mikwingwirima yobwera chifukwa cha kuyenda kwa magudumu, monga magalimoto odzaza kwambiri. Raveling amatanthauza kuphatikizika komwe kumalekanitsidwa wina ndi mzake. Asphalt ikakwera pamsewu, magazi amatuluka.

Komanso, mphero yamsewu ndi yabwino popanga mikwingwirima.

Mitundu Yogaya Misewu

Pali mitundu itatu ikuluikulu ya mphero yamsewu yothana ndi mitundu yosiyanasiyana. Zida zapadera ndi luso zimafunikira pa njira iliyonse yamphero molingana.

Fine-Milling

Fine mphero amagwiritsidwa ntchito kukonzanso pamwamba pa nthaka ndi kukonza zowonongeka. Njirayi ili motere: chotsani phula lowonongeka, konzani zowonongeka, ndikuphimba pamwamba ndi asphalt yatsopano. Kenako, yosalala ndi kusanja pamwamba pa phula latsopano.

Kukonzekera

Mosiyana ndi mphero, kukonza nthawi zambiri kumagwiritsidwa ntchito pokonza zinthu zazikulu monga misewu yayikulu. Cholinga chake ndikumanga malo oti azikhalamo, mafakitale, magalimoto, kapena malonda. The planing ndondomeko zikuphatikizapo kuchotsa lonse kuonongeka mwam'malo m'malo okha pamwamba, ntchito anachotsa particles kulenga akaphatikiza, ndi kugwiritsa ntchito akaphatikiza ku msewu watsopano.

Micro-Milling

Micro mphero, monga momwe dzinalo likusonyezera, amangochotsa wosanjikiza wochepa thupi (pafupifupi inchi imodzi kapena kuchepera) wa phula m'malo mwa pamwamba kapena pansi. Cholinga chachikulu cha mphero yaying'ono ndikukonza osati kukonza. Iyi ndi njira yabwino kwambiri yopewera kuipiraipira kwa msewu. Ng'oma yozungulira yozungulira imagwiritsidwa ntchito pogaya yaying'ono, yokhala ndi mano ambiri odulira nsonga za carbide, mano akugaya pamsewu, oyikidwa pa ng'omayo. Mano ampherowa amaikidwa mizere yosalala bwino. Komabe, mosiyana ndi ng'oma zogaya wamba, mphero zazing'ono zimangoyenda pamwamba mpaka kuya kozama, komabe kuthetsa mavuto omwewo amsewu.

Njira & Makina

Makina ozizira amphero amapangitsa mphero panjira, yomwe imatchedwanso  cold planer, makamaka yokhala ndi ng'oma ya mphero ndi makina oyendetsa galimoto.

Monga tafotokozera pamwambapa, ng'oma yamphero imagwiritsidwa ntchito kuchotsa ndi kupera pamwamba pa asphalt pozungulira. Ng'oma yamphero imazungulira mbali ina ya makina osunthira, ndipo liwiro limatsika. Amakhala ndi mizere ya zonyamula zida, atanyamula mano odula nsonga za carbide, akamsewu mphero mano. Ndi mano odula omwe amadula pamwamba pa asphalt. Zotsatira zake, mano odula ndi zotengera zida zimatha msanga ndipo zimafunika kusinthidwa zikathyoka. Zigawo zimatsimikiziridwa ndi mphero, kuyambira maola mpaka masiku. Chiwerengero cha mano mphero mwachindunji zimakhudza zotsatira mphero. Kuchuluka, kusalala.

Panthawi yogwira ntchito, asphalt yochotsedwa imagwera pa conveyor. Kenako, makina onyamula katundu amasamutsa phula lakale lopangidwa ndi phulusa kupita kugalimoto yoyendetsedwa ndi anthu yomwe ili patsogolo pang'ono pa pulanelo lozizira.

Kuphatikiza apo, mpheroyo imatulutsa kutentha ndi fumbi, motero madzi amathira kuziziritsa mgolo ndi kuchepetsa fumbi.

Pambuyo popukuta pamwamba pa asphalt mpaka m'lifupi ndi kuya kwake, iyenera kutsukidwa. Kenaka, asphalt yatsopano idzayalidwa mofanana kuti iwonetsetse kutalika kwake komweko. Asphalt yomwe yachotsedwayo idzagwiritsidwanso ntchito pamipando yatsopano.

Ubwino

Chifukwa chiyani timasankha mphero ya phula ngati njira yofunika yokonza misewu? Tanena pamwambapa. Tsopano, tiyeni tikambirane zambiri za zifukwa zazikulu.

Zotsika mtengo komanso Zachuma

Chifukwa chogwiritsa ntchito phula lokonzedwanso kapena kubwezeredwa, mtengo wake ndi wotsika kwambiri malinga ndi njira yamphero yomwe mungasankhe. Makontrakitala okonza misewu nthawi zambiri amasunga phula wobwezerezedwanso kuchokera kumapulojekiti am'mbuyomu. Mwanjira imeneyi, amatha kuchepetsa ndalama ndikuperekabe ntchito yabwino kwa makasitomala.

Kukhazikika kwachilengedwe

Asphalt yochotsedwa imatha kusakanizidwa ndi zida zina ndikugwiritsiridwanso ntchito, motero siyitumizidwa kumalo otayirako. Kwenikweni, ntchito zambiri zokonza misewu ndi kukonza zimagwiritsa ntchito phula lokonzedwanso.

Palibe Mavuto a Kukhetsa kwa Madzi & Pavement Kutalika

Mankhwala atsopano a pamwamba amatha kukweza kutalika kwa msewu komanso kuyambitsa zovuta za ngalande. Ndi mphero ya asphalt, palibe chifukwa chowonjezera zigawo zingapo zatsopano pamwamba ndipo sipadzakhala zovuta zamapangidwe monga kuwonongeka kwa ngalande.

Platondi ISO-certified katundu wa msewu mphero mano. Ngati mukufuna, ingopemphani mtengo. Otsatsa athu akadaulo adzafikira kwa inu munthawi yake
