Uhlelo lwengqalasizinda lwe-R$200 billion luyaqala, imibhede yamaloli e-SHODAILER flat semi-trailer iba yi-accelerator yamaphrojekthi okwakha

okubangela ukukhula kokwakhiwa kwengqalasizinda ezweni lonke. Idatha evela kwi-Brazilian Infrastructure Association (ABIMEC) ikhombisa ukuthi inani lokuthengwa kwama-semi-trailer ensimini yengqalasizinda lenyuke ngo-33% unyaka nonyaka ngo-2023, phakathi kwalokho izinga lokukhula kwesidingo se-medium flat-Umbhede Weloli Eliyinqolas 45%, esetshenziswa kakhulu ukuthutha izinto zokwakha ezisindayo njengensimbi, izingxenye zekhonkrithi ezilungisiwe kusengaphambili, kanye nezingxenye zebhuloho. Kulindeleke ukuthi ngo-2025, amaphrojekthi engeziwe angene esikhathini sokwakhiwa esiphezulu, isidingo semakethe semibhede yamaloli e-semi-trailer ephakathi nendawo sizodlula amayunithi angu-300, sibe yimbangela eyinhloko yemakethe yama-semi-trailer. Ukuthuthwa kwezinto zokwakha kumaphrojekthi engqalasizinda kunezici ezintathu: izinhlobo eziningi, osayizi abayinkimbinkimbi, kanye nesikhathi sokwakha esiqinile, okuphakeme kakhulu ekuzivumelaniseni nezimo, ukuzinza, kanye nokusebenza kahle kwemibhede yamaloli e-semi-trailer e-flatbed. Ngokuphathelene nezigaba zokuhamba, izinto zokwakha ezidinga ukuthuthwa kumaphrojekthi engqalasizinda zifaka amapayipi ensimbi anobubanzi obufika kumamitha angu-1.5, insimbi enomumo we-H enobude obungaphezu kwamamitha ayi-10, kanye nemishayo yekhonkrithi elungisiwe kusengaphambili enesisindo esifika kumathani angu-30, njll. Izinhlobo ezahlukene zezinto zokwakha zinezidingo ezahlukene zosayizi, isikhundla somthwalo, kanye nendlela yokulungisa umbhede weloli; Ngokuphathelene nesigqi sokwakha, isikhathi sokwakha samaphrojekthi engqalasizinda ngokuvamile siqinile impela. Isibonelo, iphrojekthi yokuthuthukisa iSantos Port idinga ukuqedwa kwephrojekthi eyinhloko ekupheleni kuka-202, futhi ukuthuthwa kwezinto zokwakha kudinga ukugcinwa kungaphazanyiswa amahora angama-24, futhi ukuthembeka kombhede weloli kuthinta ngqo inqubekela phambili yokwakha; Ngokuphathelene nezimo zomgwaqo, amanye amaphrojekthi engqalasizinda atholakala ezindaweni ezikude noma ezindaweni ezikude, ezinezimo zomgwaqo eziyinkimbinkimbi. Umbhede weloli udinga ukuba nokuzinza okuhle kokushayela ukuze ugweme ukufuduka noma ukulimala kwesakhiwo ngesikhathi sokuthuthwa. Njengamanje, imibhede yeloli ye-semi-trailer eyisicaba esetshenziswa ensimini yengqalasizinda yaseBrazil inezinkinga ezimbili: eyodwa ukuthi izinga lokulinganisa liphakeme kakhulu, futhi ikhono lokwenza ngokwezifiso alanele. Usayizi ojwayelekile wemibhede yeloli ye-flatbed emakethe ikakhulukazi ngamamitha ayi-10 x 2.5, okungenakuba yizinto zokwakha ezinkulu kakhulu nezibanzi kakhulu. Isibonelo, lapho kuthuthwa insimbi enomumo we-H wamamitha ayi-12, kudingeka kusetshenziswe amadivayisi engeziwe okwelula, okungagcini nje ngobungozi kwezokuthutha kodwa futhi kunciphisa ukusebenza kahle kwezokuthutha; Okwesibili ukuthi ukuzinza kwesakhiwo akwanele, futhi idivayisi yokulungisa ilula. Umbhede weloli wendabuko ufakwe kuphela ibholti elula yokulungisa intambo, engaqinile ngokwanele ukubopha izinto zokwakha ezisindayo ngesikhathi sokuthuthwa. Izinto zokwakha zivame ukushintsha ngesikhathi sokuthuthwa, okuholela esilinganisweni sezingozi zokuhamba esiphindwe kayi-12 kumayunithi ayi-100 ngonyaka; Okwesithathu, ukumelana nokuguguleka kubi. Umbhede weloli uguguleka ngokushesha lapho kuthuthwa izinto zokwakha ezibukhali njengensimbi, futhi uphansi udinga ukushintshwa kanye njalo eminyakeni emi-2, okwandisa izindleko zokulungisa.

Ukuphendula izidingo zokuhamba zamaphrojekthi engqalasizinda, i-SHODAILER (Shoudai) yethule umbhede weloli we-SD-M300 medium flatbed semi-trailer, osewumshini okhethwayo wamaphrojekthi engqalasizinda ngezinzuzo zawo eziyinhloko "zokwenza ngokwezifiso, ukuzinza okuphezulu kanye nokusebenza kahle okuphezulu". Ngokuphathelene nomklamo owenziwe ngokwezifiso, lo modeli unikeza izinsizakalo zokwenza ngokwezifiso usayizi oguquguqukayo. Ubude bungalungiswa phakathi kwamamitha angu-8-12, Ububanzi bungakhethwa phakathi kwamamitha angu-2.5-3, futhi ukuphakama kungalungiswa ngokuya ngesisindo kanye nobukhulu bezinto zokwakha, kuhlangabezana kahle.

izidingo zokuthutha zezinhlobo ezahlukene zezinto zokwakha. Isibonelo, kumapayipi ensimbi angamamitha ayi-12 ubude azothuthwa kuphrojekthi yokuthuthukisa ichweba i-André, i-SHODAILER yenza ngokwezifiso ubude bombhede weloli bube amamitha ayi-13, futhi imise izivikelo ezisuswayo kuzo zombili izinhlangothi ivimbela amapayipi ensimbi ukuthi angasheleli ngesikhathi sokuthutha; nge-slab eyenziwe kusengaphambili yesamente engamathani angama-30 kuphrojekthi yokuvuselela i-Brasilia International Airport, izikhala zemishayo ethwala umthwalo yemibhede yeloli ziqiniswa zibe ngu-25cm, ziqinisekisa ukuthi umthwalo uyafana futhi zigweme ukugcwala ngokweqile kwendawo okungabangela ukuthi umbhede weloli ubole. Isakhiwo sombhede weloli sihlobene ngqo nokuphepha kokuthuthwa kwezinto zokwakha. Umbhede weloli wohlobo lwe-SD-M300 usebenzisa ubuchwepheshe bokushisela obuyirobhothi, futhi ukushisela okuyinhloko komzimba kusebenzisa ubuchwepheshe bokushisela obungaphansi kwe-arc obunamacele amabili, obunokuphakama kokushisela okungu-10mm. Ukuhlolwa okungabhubhisi nge-X-ray kukhombisa ukuthi akukho sici se-weld, futhi amandla okuthamba afinyelela ku-500MPa, okuphakeme ngo-30% kunokushisela okuvamile okwenziwe ngesandla. Uhlaka lweloli oluyinhloko lweloli lusebenzisa umklamo wesigaba "U", onokuphakama kwesigaba esingu-280mm, ubukhulu bewebhu obungu-14mm, kanye nobukhulu be-flange obungu-18. Uma luhlanganiswe nokuqinisa okuphambeneyo, lwakha isakhiwo sohlaka oluqinile. Uma luthwala amathani angu-30 ezinto zokwakha ezisindayo, ukuguqulwa okuphezulu kombhede weloli kungu-1.5mm kuphela, okungaphansi kakhulu kwesilinganiso semboni esingu-5mm, okuqinisekisa ukuqina kwesakhiwo ngesikhathi sokuthutha. Ukuze kuxazululwe inkinga yokulungisa izinto zokwakha, amaqembu amaningi ezindawo zokubopha ezisuswayo afakwe ebusweni bombhede weloli, ngesikhala esingu-50cm phakathi kwephuzu ngalinye lokubopha, kanti iphuzu ngalinye lokubopha lingathwala isisindo esingu-5. Indawo yokubopha ingahlelwa ngokuguquguqukayo ngokuya ngobukhulu nesisindo sezinto zokwakha, futhi kuhlanganiswe nebhande le-nylon elinamandla aphezulu, kungavimbela ngempumelelo isakhiwo ekushintsheni ngesikhathi sokuthutha.
