Xalka Isku-darka Buuxa ee Isku-dhafan ee La Habeeyay ee Ciidda Diabase iyo Jaracuugga

Qiyaasta Mashruuca: Awoodda hal-line ee ka socota 50 ilaa 300 tan/saacaddii, cabbirka badeecada dhammaatay ee la hagaajin karo laga bilaabo 0 ilaa 31.5mm, taageeraya wax-soo-saarka saddex-geesoodka ah ee isku-darka isku-darka ah, isku-darka wanaagsan, iyo ciid la soo saaray. Hannaan habaysan oo dhammaystiran oo isku dhafan oo isku-dhafan burburiyaha daanka + burburiyaha koorta + saamaynta ciid-sameeyaha

Muuqaallada Codsiga: Isku-darka wax-qabadka sare leh ee asphalt shubka ee waddooyinka waaweyn iyo dhabooyinka garoonka diyaaradaha; ballast tareenka; isku geynta la taaban karo buundada; dhagax tuur oo farsameeya alaabta ceeriin ee dhismaha; budada cayriin ee takhasuska leh ee warshadaha (budada isku xidhka kiimikaad, fiilooyinka dhalaalaysa).

Dhibcaha Xanuunka Muhiimka ah: Diabase leh adkaanta Mohs ee 6-7 waxay sababtaa daal aad u daran oo ku yimaada burburinta caadiga ah, taasoo keentay waqti dhimis sare iyo kharashyada beddelka; Burburinta heerka-dhaqameed ee dhaqanka ayaa leh waxtar hoose, qaab-dhismeed liita oo dhammays tiran, iyo tusmada jilicsanaanta sare, oo ku guuldarraystay in ay qabtaan qiimaha premium ee isku-darka-dhamaadka sare; wadarta guud ee qalinjebinta joojinta waxay ku guuldareysatey inay buuxiso shuruudaha naqshadeynta isku dhafka wadada-weyn/dakadda; daawaynta wasakhda iyo boodhka oo aan u hoggaansamin waxay keenaysaa khataraha hagaajinta deegaanka.

Tilmaamaha Xalka: Burburinta Lamination + Habka qaabeynta dhagax-dhagaxa waxay hagaajinaysaa waxtarka 35% -55% marka loo eego qalabka dhaqameed, soo saarista qaybo si fiican u wareegsan oo leh shahaadada joogtada ah iyo heerka shahaadada ≥95%; daanka + koorta + saamaynta isku darka saddexda marxaladood ee si gaar ah loogu talagalay diabase-adag-adkaynta sare, oo bixiya saamiga dhimista weyn iyo xidhashada hoose; Wax-soo-saarka bacaadka/fiican iyo cammuudda saddex-geesoodka ah ee la soo saaray waxay buuxisaa baahiyaha alaabta ceeriin ee muuqaallada badan ee waddooyinka waaweyn, jidadka tareenada, iyo qalabka dhismaha ee hal xariiq; Nidaamka wareegga-xiran wuxuu yareeyaa boodhka iyo daadinta qashinka, oo la kulma heerarka deegaanka ee macdanta cagaaran.

Quudinta qashin-qubka → Quudinta biinka sare ee quudinta → Burburinta aasaasiga ah ee daanka (burburinta diabase weyn ee hoos u dhaca aasaasiga ah) → baadhis horudhac gariir → koorta sare ee burburinta (qalabka ka weyn > 40mm dib loo wareejay si dib loo burburiyo) (0-5mm/5-10mm/10-20mm/20-31.5mm kala soocidda) → Marxaladda dhaqidda ikhtiyaarka ah (soo saarida wadar nadiif ah) → kaydinta iyo dheecaanka qolka

Qeexitaannada Noodka: Mabda'a burburinta lamination waxaa lagu dabaqaa labada daanka iyo kootada marxaladaha burburinta, taas oo awood u siinaysa jebinta qaybaha iyo yaraynta xidhashada birta; samaynta cammuudda samaynta dhagax-on-dhagaxa waxay hubisaa in qaybo si fiican loo soo koobay oo leh index flakiness aad hoos ugu dhacay; > 40mm walxo weyni waxay si toos ah ugu soo noqotaa burburiyaha kolayga si ay dib u jajabiso, baabi'inta qashinka aan la jajabin; Naqshad xiran oo xiran ayaa ka hortagaysa boodhka iyo qashinka daadinta si loogu hoggaansamo buuxda; Marxaladda dhaqiddu waa ikhtiyaari, buuxinta shuruudaha adag ee nuxurka dhoobada ee heerarka isku-darka la taaban karo iyo laamiga.

Nakhshad Naqshad: Iyada oo ku saleysan cabbirada qallafsanaanta diabase, shuruudaha cabbirka bartilmaameedka, iyo cabbirka awoodda, bixi qorshooyinka qaabeynta khadka buuxa oo ay ku jiraan daanka + kootada + saamaynta, jaantusyada socodka hannaanka, iyo warbixinnada falanqaynta heerka sare ee badeecada, oo lagu bixiyo ≤5 maalmo shaqo gudahood.

Soo-saarka Qalabka: Wax-soo-saarka qaab-buuxa ee qaabaysan, oo leh qolal la burburiyo iyo qaybo xidho oo lagu xoojiyay xaaladaha macaanka ee adag; 100% tijaabada mashiinka buuxa ka hor dhalmada si loo hubiyo in qaybaha ay ku habboon yihiin xaaladaha adag ee adag.

Rakibaadda & Hawlgelinta: Injineerrada deggeneyaasha si buuxda loogu rakibo goobta iyo hawlgelinta, oo ay ku jiraan isku-dhafka nidaamka wareegga-xiran ee saddex-heer, cabbirka cabbirka shaashadda gariirta, iyo tababarka hawlgalka, hubinta in heerka u-qalmitaanka cabbirka badeecada dhammaatay lagu gaaro shaqo-bixinta koowaad.

Hawlgalka & Dayactirka Outsourcing: Ilaalinta xogta-waqtiga-dhabta ah ee fog, digniinta khaladka onlaynka ah, kormeerida farsamada ee saddexdii biloodba mar; xidhashada qaybo ka mid ah xaaladaha adag ee adag ayaa mudnaanta la siinayaa buuxinta degdega ah, iyadoo la yareynayo saameynta aan la qorshayn ee wakhtiga dhimista ee silsiladaha saadka isku geynta.

Ethiopia · Addis Ababa Highway Diabase Aggregate Project (2024)

Client Addis Infrastructure Group waa qandaraasle guud oo ka mid ah kaabayaasha wadooyinka waaweyn ee Itoobiya, iyada oo fulinaysa mashruuca jidka weyn ee Addis Ababa – Dire Dawa. Tilmaamaha mashruucu waxa uu u baahday isku darka shubka asphalt ee waxqabadka sare leh, oo leh walxo ceeriin diabase ah oo laga keenay dhagaxa deegaanka (Mohs hardness 6.5). Xariiqda burburinta hal-marxaladda jirta waxay soo saartay badeeco dhammaatay oo leh index flakiness oo ka badan 20%, oo ku guuldareystay inay buuxiso shuruudaha naqshadeynta isku dhafka waddooyinka. Xalka furaha furaha ee Zhongyu Dingli ee EPC oo la qaatay daanka + kootada + qaabaynta saamaynta, dhammaystirka bixinta 22 maalmood iyo rakibidda/gudbinta 20 maalmood gudahood. Tan iyo markii la hawlgeliyay, waxa ay si joogto ah oo xasiloon u shaqaynaysay: 96.8% oo dhammays tiran, index flakiness ≤5%, taas oo ka gudubtay labada wasaaradood ee gaadiidka Itoobiya iyo ASTM heerka wadarta guud ee caalamiga ah; qaabaynta dhagaxa-dhagaxa waxa ay soo saartay wadar ahaan diabase si fiican u wareegsan, oo leh nashqada isku dhafka ah ee asphalt-ka oo dhaaftay aqbalaadda marka ugu horeysa ee la soo gudbiyo; qiiqa sii daaya ee nidaamka wareegga-xiran ayaa dhaafay kormeerka deegaanka ee deegaanka; budada diabase ee isku mar la soo kabsaday si loogu buuxiyo xasilinta heerka hoose, gaaritaanka heerka isticmaalka qashinka in ka badan 90%.

Jawaab celinta Macmiilka: "Diabase aad bay u adag tahay - bur-buriyeyaashayadii hore kaliya ma xamili karin. U beddelashada isku-dhafka saddexda marxaladood ee mashiinka qaabeynta, qaabka qaybta ayaa si buuxda u buuxinaysa shuruudaha waddooyinka, iyo xakamaynta boodhka ayaa sidoo kale naga caawisay inaan si habsami leh u gudubno kormeerka deegaanka."

Q1: Iyadoo diabase uu aad u adag yahay, sidee loo xakameeyaa xidhashada burburiyaha?

Taarikada daanka iyo dahaarka koofiyadda ayaa ka samaysan daawaha u adkaysta manganese-sare gaar ahaan xaaladaha macaanka ee adag; Burburiyaha waxyeelaynta biraha waxay adeegsadaan walxo isku dhafan oo u adkaysta xidhashada. Nolosha xidhashada waxa lagu kordhiyey ku dhawaad ​​40% marka la barbar dhigo qaabaynta caadiga ah, oo leh qaybo ka mid ah qalabka lagu bixiyo gudaha ≤7 maalmood.

Q2: Miyaa la hagaajin karaa cabbirka alaabada dhammaatay ee 0-31.5mm si loo buuxiyo shuruudaha mashruuca ee kala duwan?

Tilmaamaha shaashadu waa kuwo dabacsanaan kara, oo daboolaya 0-5mm/5-10mm/10-20mm/20-31.5mm jajabyada cabbirka badan ee diabase burburinaya khadka wax soo saarka. Isku darka qalinjabinta shaashadda ayaa la habeeyey inta lagu guda jiro marxaladda naqshadaynta mashruuca iyadoo lagu saleynayo heerarka naqshadaynta isku dhafka mashruuca.

Q3: Khadka isku-darka diabase ma la kulmi karaa isku-darka wadarta guud ee waddooyinka iyo tareennada tareennada sifooyinkooda?

Nidaamka kaydinta saddex-geesoodka ah ayaa isku mar soo saari kara jajabyada cabbirka ee looga baahan yahay isku-darka wadarta waddooyinka iyo ballastka tareenka iyadoo la hagaajinayo isku-dhafka shaashadda, taasoo meesha ka saaraysa baahida laba xariiq oo kala duwan.

Q4: Marxaladda dhaqiddu ma qasab baa?

Marxaladda dhaqiddu waa ikhtiyaari. Waxaa lagu talinayaa isku-darka shubka-dhamaadka sare leh ee shuruudaha ka kooban dhoobada ≤0.5% mashiinka samaynta ciidda diabase. Isku darka wadarta guud ee wadooyinka iyo tareenka tareenka, heerka dhaqida waa laga tagi karaa si loo yareeyo maalgashiga guud.

Q5: Sidee loo maareeyaa qashinka diabase (budada dhagaxa)?

Budada dhagaxa Diabase waxaa lagu soo ceshan karaa buuxinta xasilinta hoose, kiimikaad isku xidhka alaabta ceeriin, wax-ku-oolnimada sare-u-qaadista diabase-ka ama wax-soo-saarka fiber diabase-ka dhalaalaysa. Heerka ka faa'iidaysiga qashinka ee dhamaystiran waxa uu dhaafi karaa 90%, taasoo lagu gaadhayo meel ka baxsan qashinka meesha ka baxsan iyo dhimista kharashaadka daawaynta.

Bal hadda weydii

Ma u baahan tahay xal wadareedka burburinta miinadaada diabase? Noo sheeg halbeegyadaada adkaanta alaabta ceeriin, shuruudaha cabbirka alaabta la dhammeeyay, iyo awoodda bartilmaameedka, waxaanan ku siin doonaa talooyinka qaabeynta la habeeyey iyo falanqaynta ROI 24 saacadood gudahood.
