Ngwa Ngwa nke Ndozigharị Asphalt Dị Irè: Ihe Ịma Aka n'Ụlọ Ọrụ;

Tupu anyị eleba anya n'ike nke DY-300, ọ dị mkpa ịghọta ihe ịma aka ndị na-eche ndị otu na-arụzi asphalt ihu n'ụwa niile. Dịka International Road Federation (IRF) si kwuo, ihe karịrị 40% nke okporo ụzọ asphalt zuru ụwa ọnụ chọrọ mmezi n'ime afọ 5-7 nke owuwu, mana ụzọ ọdịnala na-esiri ike imezu ihe a chọrọ. Dịka ọmụmaatụ, igwe e ji aka rụọ - dabere na ngwaọrụ aka - nwere ike ịhazi naanị mita 20-30 nke elu kwa elekere, ebe igwe e ji aka rụọ ochie na-ahapụkarị elu ndị na-adịghị mma nke chọrọ ka e mee ka ha dị nro, na-abawanye oge ọrụ na ọnụ ahịa.

Ọzọkwa, ihe mkpofu ihe bụ nnukwu nchegbu. Nhazigharị ihe owuwu ọdịnala na-ewepụ akwa asfalt dum (ọtụtụ mgbe 5-10 cm) ọbụlagodi na ọ bụ naanị 1-2 cm dị n'elu mebiri emebi, nke na-eduga na oke ihe a tụfuru 30-40% nke na-emesịa banye n'ebe a na-ekpofu ihe.

Dịka American Association of State Highway and Transportation Officials (AASHTO) si kwuo, 1,200–3,000 kwa elekere. Ihe ịma aka ndị a na-egosi mkpa ọ dị maka ngwọta nke na-ahazi ọsọ, nkenke, na nkwado - kpọmkwem ihe igwe igwe DY-300 na-enye.

Ike Ndị Dị Mkpa nke DY-300: Ọkachamara Injinịa Maka Mmegharị Ahụ;

E mere DY-300 iji dozie oke nke usoro ọdịnala site na ọtụtụ atụmatụ dị elu nke na-ebute arụmọrụ, nkenke, na ịdị mfe iji. N'ime isi ya, igwe ahụ na-eji sistemụ hydraulic dị elu nke jikọtara ya na drum igwe nri nke mita 1.8 n'obosara—nke sara mbara karịa drum mita 1.2–1.5 nke ọtụtụ ndị asọmpi. Drum a sara mbara na-enye DY-300 ohere ikpuchi ruo mita 120 nke elu asfalt kwa elekere, mmụba nke 40–60% na mmepụta ma e jiri ya tụnyere igwe igwe nri ọkọlọtọ. Dịka ọmụmaatụ, enwere ike imecha okporo ụzọ okporo ụzọ abụọ nke kilomita 1 (chọrọ mita 4,000 nke igwe igwe nri) naanị awa 34 na DY-300, ma e jiri ya tụnyere awa 50–60 na ụdị ochie.

Nkọcha bụ ihe ọzọ e ji mara DY-300. E ji njikwa omimi nke GPS na teknụzụ nhazi ọkwa laser mee ya, igwe ahụ na-ejigide izi ezi nke omimi igwe nke ±1 mm—dị oke mkpa maka ijide n'aka na nkwadebe elu ahụ dị otu tupu e megharịa ya. Nke a na-ewepụ mkpa ọ dị ime ka ọ dị nro nke abụọ, belata usoro ọrụ ma belata ihe mkpofu ihe. A na-etinye drum igwe n'onwe ya ezé tungsten carbide 80, nke edobere n'usoro gburugburu iji hụ na e bepụrụ ya ma gbochie ya ịdọwa elu. Ezé ndị a nwekwara ike ịgbanwe, ha na-adịgide ruo awa 50-80 nke ojiji na-aga n'ihu—ugboro abụọ karịa ezé ígwè nkịtị—na-ebelata ọnụ ahịa mmezi na oge nkwụsị.

A naghị eleghara ahụmịhe onye ọrụ anya. DY-300 nwere imewe kabọd nwere njikwa ergonomic, ngosipụta ihuenyo mmetụ aka nke inch iri, na visibiliti ogo 360—na-ebelata ike ọgwụgwụ onye ọrụ n'oge ọrụ ogologo oge. Igwe a dịkwa obere (mita 6.2 n'ogologo, mita 2.5 n'obosara) ma nwee radius ntụgharị nke mita 4.8, nke na-eme ka ọ dabara adaba maka mpaghara obodo nwere okporo ụzọ dị warara ma ọ bụ nkuku siri ike. Maka ọrụ buru ibu, enwere ike ijikọ DY-300 na sistemụ mbupu ihe raara onwe ya nye nke na-ebu asfalt a gwuru ozugbo n'ime gwongworo, na-ewepụ mkpa maka nchekwa dị n'etiti na ọrụ ndị ọzọ na-eme ka ọ dị mfe.

Ngwa Ndị Dị n'Eziokwu: Gosipụta Ịrụ Ọrụ nke Ọma n'Ọrụ;

Arụmọrụ DY-300 abụghị naanị echiche—a kwadoro ya n'ọtụtụ ọrụ mmezi dị elu n'ofe kọntinent. Na 2023, obodo Berlin, Germany, jiri igwe DY-300 iri na abụọ rụzie ụzọ obodo dị kilomita iri na ise tupu nnukwu ihe omume mba ụwa. Ọrụ ahụ chọrọ ịkpụcha mita square mita 60,000 nke elu asphalt nwere omimi ebumnuche nke 2 cm (iji dozie mmebi na mgbawa). Site na iji teknụzụ GPS nke DY-300, ndị otu ahụ nwetara omimi otu ebe n'ofe 98% nke mpaghara ahụ, belata ihe mkpofu ihe site na 35% ma e jiri ya tụnyere ọrụ ha nke 2021 (nke jiri igwe igwe ochie). Emechara ọrụ ahụ n'ime ụbọchị 28—izu abụọ tupu oge eruo—na-ebelata nsogbu okporo ụzọ n'etiti obodo.

Na mba Amerịka, Ngalaba Njem nke Texas (TxDOT) tinyere igwe DY-300 iji rụzie akụkụ dị kilomita iri abụọ nke Interstate 35, nke nwere nnukwu oghere na mgbawa n'ihi nnukwu okporo ụzọ gwongworo. Sistemụ ike DY-300 nyere ya ohere ịkpụ asfalt siri ike (nke gbakọrọ ihe karịrị afọ iri) n'akwụsịghị akwụsị, ebe sistemụ mbugharị ahụ mere ka o kwe omume ibu ihe e ji gwerie ihe mgbe niile. TxDOT kọrọ mmụba 42% na mmepụta kwa ụbọchị ma e jiri ya tụnyere ngwa ha gara aga, e mekwara ka asfalt ahụ e ji gwerie ihe megharịa n'ebe ahụ (gwakọta ya na mkpokọta ọhụrụ) iji mepụta 30% nke asfalt ọhụrụ e ji emegharị ihe—na-ebelata ọnụ ahịa ihe site na $120,000.

Ihe ndị a na-egosi uru dị mkpa nke DY-300: ikike ya imeghari na mkpa ọrụ dị iche iche, site n'okporo ụzọ obodo ruo n'okporo ụzọ ukwu, ma na-enye nsonaazụ na-aga n'ihu n'ihe gbasara ọsọ, nkenke, na nchekwa ego.

Nkwado: Ịdabere na Ebumnuche Gburugburu Ebe Obibi Ụwa;

N'oge a na-elekwasị anya n'ịdịgide, DY-300 pụtara ìhè maka imewe ya nke na-adịghị emebi gburugburu ebe obibi. Dịka ekwuru, igwe igwe na-ebelata ihe mkpofu ihe site na 30–40% ma e jiri ya tụnyere usoro ọdịnala. Ọzọkwa, a naghị atụfu asphalt a na-agbaze (nke a maara dị ka pavement asphalt a gbaghaara agbaze, ma ọ bụ RAP) naanị—enwere ike imegharị ya ka ọ bụrụ ngwakọta asphalt ọhụrụ. Usoro igwe DY-300 na-emepụta RAP nwere nha nha nha, na-eme ka ọ dịrị mfe itinye ya na ngwakọta ọhụrụ (ruo 50% RAP n'ọnọdụ ụfọdụ), na-ebelata mkpa maka ngwakọta virgin na bitumen.

Ike dị ike ọzọ. DY-300 na-eji ọkpọkọ hydraulic nke na-agbanwe agbanwe nke na-agbanwe mmepụta ike dabere na ibu, kama ịrụ ọrụ n'ike zuru oke mgbe niile. Nke a na-ebelata oriri mmanụ site na 15–20% (ma e jiri ya tụnyere ọkpọkọ ndị na-agbanwe agbanwe), na-ebelata mwepụta carbon site na ihe dị ka tọn 0.8 kwa awa 100 nke ọrụ. Igwe ahụ na-emezukwa ụkpụrụ mwepụta ikpeazụ nke Euro Stage V na EPA Tier 4, na-ahụ na e rubere isi na iwu gburugburu ebe obibi zuru ụwa ọnụ siri ike.

Mmechi: DY-300 dị ka ihe na-akpali akpali maka mmezi asphalt mara mma;

Igwe igwe e ji egwe ihe DY-300 abụghị naanị ngwa ọrụ—ọ bụ ngwọta zuru oke nke na-edozi nsogbu ndị bụ isi nke nhazigharị elu asphalt: enweghị ike ịrụ ọrụ nke ọma, enweghị nhazi zuru oke, ihe mkpofu, na mmetụta gburugburu ebe obibi. Site na ijikọta mmepụta dị elu (mita 120 kwa elekere), nkenke pụrụ iche (± 1 mm njikwa omimi), na imewe na-adịgide adịgide (belata ihe mkpofu na mwepụta), DY-300 na-enye ụlọ ọrụ njem na ndị ọrụ nkwekọrịta ohere imecha ọrụ ngwa ngwa, na ọnụ ahịa dị ala, yana obere akara gburugburu ebe obibi.

Ka akụrụngwa ụwa na-akawanye njọ, ọchịchọ maka mmezi dị irè na-amụbakwa, DY-300 na-anọchite anya ọdịnihu nke mmezi asphalt—ọdịnihu ebe a na-arụzi okporo ụzọ ngwa ngwa, n'enweghị nsogbu, na n'ụzọ ga-adịgide adịgide, na-eme ka netwọk njem nọgide na-adị irè ruo ọtụtụ iri afọ ndị na-abịa. Maka òtù ọ bụla na-achọ imeziwanye usoro mmezi asphalt ha, DY-300 abụghị naanị nhọrọ—ọ bụ ihe ngwọta kachasị mma.
