Mupi wezvishandiso zvekuvaka kwemakore makumi matatu.
Kusarudza banga redhaimani hakusi kungosarudza dhayamita chaiyo uchitarisira kuti banga racho richakukanganwira. Banga racho rinofanira kuenderana nechinhu chakagadzirwa, saha, kudzika kwekucheka uye mamiriro ebasa. Konkriti, asphalt uye slabs dzakasimbiswa zvese zvinogona kutaridzika se "zvinhu zvakaoma" kana uri kure, asi kune banga redhaimani zvinoita zvakasiyana zvikuru.
Mutemo wekutanga uri nyore: zvinhu zvakaoma zvinowanzoda chisungo chakapfava, nepo zvinhu zvakapfava uye zvinokwesha zvinoda chisungo chakaoma. Norton Abrasives inotsanangura kusarudzwa kwesimbi yesimbi yedhaimani nepfungwa imwecheteyo yezvakapesana: zvisungo zvakasimba zvinoenderana nezvinhu zvakapfava zvinokwesha senge asphalt, nepo zvisungo zvakapfava zvichienderana nekongiri yakaoma. Pakutanga zvinonzwika sezvisingatarisirwi, asi zvine musoro kana ukayeuka kuti chisungo chesimbi chinofanira kupera nekukurumidza kwakakodzera kuti madhaimani matsva abudiswe pachena.
Mutemo wekukurumidza: sarudza banga nechinhu chekutanga, wobva wasimbisa mhando yechisungo, dhizaini yechikamu, saizi yesaha, kudzika kwekucheka uye kushandiswa kwakanyorova kana kwakaoma.

Shandisa chati iyi sesefa yekutanga. Kana uchida kuenzanisa kwakadzama pakati pezvinhu zvekufamba netsoka, verenga gwara iri pa Sarudzo yebanga resaha rekongiri vs asphalt Sarudzo yekupedzisira yebanga inoenderana nedhayamita yebanga, saizi yearbor, simba resaha, kudzika kwekucheka, RPM rating uye kana mvura iripo.
Kongiri yakagadzirwa yakaoma, kunyanya kana iine aggregate yakakora. Inodzima madhaimani akafumurwa, saka chisungo chinofanira kupfeka zvakakwana kuti chibudise madhaimani matsva. Madhaimani ekushandisa blade anowanzo tora kongiri iri pa3,000 psi kana pasi sechinhu chakapfava uye kongiri iri pa6,000 psi kana kupfuura sechinhu chakaoma. Izvi zvinopa mainjiniya nevatengi nzvimbo inobatsira yekutanga vasati vatarisa mhando ye aggregate uye simba rayo.
Asphalt yakapfava pane kongiri yakagadzirwa, asi inonyanya kukwesha. Jecha nejecha riri muasphalt zvinogona kudya muromo webanga kana panga isiriyo zvikashandiswa. Ndosaka banga redhaimani reasphalt richiwanzoshandisa chisungo chakasimba uye dziviriro isina kuchekwa. Mumutauro wakajeka, asphalt haisi "kongiri iri nyore." Imuchina wekukuya blade wakapfeka jira remugwagwa.
Masirabhu akasimbiswa anowedzera rimwe dambudziko: simbi. Chidimbu chedhaimani chekongiri chine rebar chinoda zvikamu zvakasimba, kumanikidzwa kwakasimba kwekudya uye kutonhodza zvakanaka. Kucheka nemvura kazhinji ndiyo sarudzo yakangwara nekuti kubata simbi kunokonzera kupisa nekukurumidza.
| Rudzi rweBond | Zvakanakira | Kana Zvikashandiswa Zvisizvo |
|---|---|---|
| Chisungo chakapfava | Kongiri yakasimba, kongiri yakaoma, kongiri yakasimbiswa | Inopfeka nekukurumidza zvakanyanya muasphalt |
| Chisungo chepakati | Basa rekongiri nemabasa akasiyana-siyana | Zvinogamuchirwa, asi hazvisi nguva dzose zvakanaka |
| Chisungo chakaoma | Asphalt, kongiri yegirini, bhuroko rinokwesha | Inogona kupenya pakongiri yakaoma |
Aggregate inokoshawo. Mamwe magwara ekusarudza mablade anoronga aggregate yakakura kupfuura 3/4 inch seaggregate hombe, nepo aggregate iri pasi pe 3/8 inch iri nyore kucheka asi inogona kupfeka bande nekukurumidza. Ndosaka ma slabs maviri ane simba rakafanana rekumanikidza achigona kucheka zvakasiyana. Konkriti ine pfungwa yekuseka, uye inowanzoiviga mukati meaggregate.
Kana iri kongiri yakagadzirwa zvakanaka, tanga nebanga redhaimani rekongiri rakapatsanurwa. Kana kongiri yacho yakaoma kana kuti banga rikatanga kupenya, enda kune chisungo chakapfava. Kana kongiri yacho yakapfava uye ichikwesha, enda kune chisungo chakaoma. Kuti uwane dzimwe nzira dzekushandisa dzakabatana, unogona zvakare kutarisa pane banga resaha rekongiri peji.
Sarudzo yebanga resaha rekongiri inofanirawo kuenderana nesaha. Semuenzaniso, Husqvarna K 770 zvirevo nyora banga re 14 inch , kudzika kwekucheka kwe 5 inch , kubuda kwe 5 hp uye kumhanya kwe peripheral kwe 18,000 fpm . Nhamba idzodzo dzinotiyeuchidza kuti kusarudza banga hakusi kwechinhu chete. Dhayamita, saizi ye arbor uye chiyero chekumhanya zvinofanirwa kuenderana nemuchina.
Pakucheka asphalt, shandisa banga redhaimani reasphalt rakatsaurirwa. Rinofanira kunge rakasimba, rakachekwa zvakanaka uye rakadzivirirwa. Norton anoti kucheka pasi pevhu kunogona kukonzera kurasikirwa nechikamu, uye anokurudzira kuchengetedzwa pasi pevhu kana kuwedzera kwemvura apo zvinhu zvinokwenya zvinorwisa simbi.
Chidimbu chakajairika cheasphalt chinoratidza kuti zvishandiso izvi zvinogona kunge zvakagadzirwa sei. CMT inonyora banga reasphalt re 300 mm ine chikamu chakachengetedzwa chisina kuchekwa che 8 mm , bhora re 20 mm uye 6,400 rpm yepamusoro , uye inoratidza kuti haina kukodzera kongiri kana kongiri yakasimbiswa. Pamabasa ekufamba neasphalt, batanidza banga nekucheka kwakakodzera, senge muchina wekucheka kongiri yepeturu wekucheka nzira yeasphalt nekongiri .
Kana iri kongiri yakasimbiswa, shandisa banga rakarongwa kuti ribate rebar. Chisungo chakapfava kusvika chepakati chinobatsira kuti banga rirambe richicheka kongiri yakaoma, nepo kuvakwa kwakasimba kwakapatsanurwa kuchibatsira kuti irambe ichirarama pakupisa uye pakurovera kana simbi yaonekwa. Zvikamu zvakasungirirwa nelaser zvinowanzo shandiswa pakucheka kwakakura nekuti kubatana kwezvikamu kwakasimba kana paine mamiriro akaoma.
Usamanikidza banga kana rasvika pachigadziko. Chengeta chikafu chakadzikama, shandisa mvura kana zvichibvira uye usatenderedza saha riri pamucheto wekucheka. Kana banga rikatanga kupfungaira, saha rinotanga kusvetuka-svetuka, kana kuti mushandi anotanga kutaurirana nemuchina, mira woongorora kuti chii chakagadzirwa.
Kucheka netsvina hakusi kungoshanda kwenguva refu kwebanga chete. Nhungamiro yekuvaka silica yeOSHA inoisa mwero wekushanda kwesimbi inofema inofema pa25 μg/m³ uye muganho unobvumidzwa wekuratidzwa pa50 μg/m³ , zvese seavhareji yenguva inorema maawa masere. Izvi zvinoita kuti kuchekwa kwemvura kuve sarudzo yekudzora guruva pamwe nesarudzo yekutonhodza.
Kucheka netsvina kunobatsira pakucheka netsvina pfupi uye pakugadzirisa, asi chete nebanga rakarongwa kuti rishandiswe netsvina. Usambofa wakaomesa nebanga rakanyorova chete. Izvozvo hazvisi zvekugadzira simbi; inzira inokurumidza yekupisa, kuiisa mugirazi uye banga rinongoerekana rava simbi yakachekwa inodhura zvikuru. Kuti uwane kuenzanisa kwakadzama, verenga kucheka kongiri yakanyorova vs yakaoma .
Banga rakanaka pajecha risiri iro rinoramba richipa mhedzisiro yakaipa. Usati wacheka, simbisa dhayamita rejecha, saizi yearbor, RPM yepamusoro, kudzika kwekucheka, simba remvura uye simba rejecha. Kana basa iri richisanganisira kucheka nzira refu, kugadzirisa mugwagwa kana kugadzira trenching, gwara iri riri pamusoro nzira yekusarudza mugwagwa wakakodzera wekucheka kongiri neasphalt ndiyo nhanho inotevera iri nani.
Kune varidzi vemakondirakiti vachienzanisa michina, gwara guru rekugadzira matombo ekongiri nemichina yekucheka migwagwa inopa ruzivo rwakawanda pamusoro pemhando yemuchina, kudzika kwekucheka uye basa rekufamba netsoka. Kana uchida maonero akafara ekushandiswa, chinyorwa pamusoro pe mabhenefiti ekugadzira kongiri, asphalt uye nzira dzemugwagwa zvakare inyaya inobatsira yemukati.
Chikanganiso chekutanga kushandisa banga rimwe chete pakugadzira kongiri, asphalt uye slabs dzakasimbiswa. Chechipiri kuregeredza kuoma kwebond. Chechitatu kupomera saha mhosva kana dambudziko guru riri remagirazi ebanga, RPM isiriyo, kutonhora kusina kunaka kana kuti material match isiriyo.
Kana banga redhaimani rikarega kucheka, tarisa chisungo, zvinhu, kumhanya kwesaha uye mvura usati wasunda zvakasimba. Banga rakanaka rinofanira kucheka nekumanikidzwa kwakasimba. Kana uchifanira kusveta saha, banga racho ringangodaro riri kukuudza chimwe chinhu. Kana ukatadza, shandisa gwara iri pa kupenya kwebanga redhaimani uye chikonzero nei banga richimira kucheka .
Shandisa chati yekusarudza banga redhaimani kuti usarudze, wobva wasimbisa zvinhu zvina: zvinhu, chisungo, saw match uye nzira yekucheka. Kana uchida simende, funga nezvesimba uye aggregate. Kana uchida asphalt, funga nezve abrasion uye kudzivirira pasi pekucheka. Kana uchida simende yakasimbiswa, funga nezvesimbi, kupisa uye kutonhora.
Banga rekurudyi haringocheki nekukurumidza chete. Rinotonhorera, rinogara kwenguva yakareba, rinoderedza nguva yekushanda uye rinoita kuti mushandi aite seakaronga zvese kubva pakutanga.
