Zeziphi iintlobo zezixhobo ezisetyenziswa kulwakhiwo lweendlela ukukhawulezisa iiprojekthi?
Wakha waqhuba imoto wadlula kwindawo yomsebenzi omkhulu waza wazibuza, “ Bakwazi njani ukuhambisa uthuli olungaka ngosuku olunye? ” Impendulo ikwiqela leematshini ezahlukeneyo ngokumangalisayo, nganye yenzelwe umsebenzi othile. Kweli nqaku sizahlulahlula iintlobo zezixhobo ezisetyenziswa ekwakheni iindlela , isizathu sokuba abakhi bakhethe enye kunenye, kunye nendlela umxube ofanelekileyo ogcina ngayo iishedyuli (kunye nohlahlo-lwabiwo mali) zingahambi ecaleni.
Amaqhawe Ahamba Ngomhlaba Anzima: Ukusuka Kwi-Scrapers ukuya Kwi-Scrapers-Plus
Ngaphambi kokuba kubekwe umaleko wokuqala wegrabile, umhlaba kufuneka ulungelelaniswe ube yimeko entle. Ii-motor graders zilawula eli nqanaba, zicheba amabala aphezulu kwaye zizalise aphantsi ngokuchanekileyo okunokumangalisa abaqhubi bokuqala. Ii-scrapers—ezo zitya zinkulu ezinamavili—zirhuqa kwaye zibeke umhlaba kwindawo enye, zinciphisa isidingo seelori ezongezelelweyo. Kwindawo enamatye, i-bulldozer exhotyiswe nge-ripper ikrazula amabala axineneyo ngokukhawuleza kunokuba unokuthi “i-hardpan.” Inyani eyonwabisayo: i-scraper enye yanamhlanje inokuhambisa umhlaba owaneleyo ukuzalisa ichibi le-Olimpiki ngaphantsi kweeyure ezimbini, yiyo loo nto abakhi bafunga ngabo xa ixesha lincinci.
Izinto Zokuzinzisa Umhlaba: Abagcini Abazolileyo Bobomi Bokuhamba Ngeenyawo Bexesha Elide
Xa iprofayili ijongeka ilungile, i-sub-grade isafuneka ihlale injalo. Khangela izinto ezigcina umhlaba ucocekile, oomatshini ababonakala ngathi zii-rototiller ezinkulu kodwa bephethe ubuchule obuphezulu. Bacola amaqhekeza, bafake ilayimu okanye isamente, baze bashiye iqonga eliqinileyo njengelitye. Ukutsiba eli nyathelo kufana nokwakha indlu esihlabathini esikhawulezayo; ewe, ungakwenza oko, kodwa uya kuzisola okokuqala xa kuvela umngxuma ngaphambi kokuba ipeyinti kwi-guardrails yome.
Ii-Asphalt Pavers: Ubushushu obuchanekileyo kwi-160 °C
Xa abantu becinga ngokwakhiwa kwendlela, badla ngokucinga nge-asphalt paver, i-hopper yayo ikhazimla ngomxube omnyama oshushu. Ii-pavers zanamhlanje zisebenzisa ii-sonic sensors ukugcina ubukhulu be-mat bungaphakathi kwe-intshi enye, ngelixa ii-screed plates zingcangcazela nge-3,000 rpm ukuze zikhuphe iipokotho zomoya. Isiphumo? Umphezulu uthambile ngokwaneleyo ukuze umfanekiso we-asphalt entsha ungaphepheki kwi-Instagram. Icebiso lebhonasi: khangela ii-pavers ezine-screeds ezinobubanzi obuguquguqukayo; zivumela abasebenzi ukuba balungelelanise endaweni yokuma ukuze batshintshe ii-plates—ixesha elongiweyo lilingana nemali elongiweyo.
Iimashini Zokuxinana: I-Tandem, i-Pneumatic, kunye ne-Intelligent
I-asphalt entsha ilungile kuphela xa ixinene. Iirola zentsimbi ezidibeneyo zibonelela nge-"breakdown" yokuqala, zilandelwa ziirola zethayi eziphefumlayo ezixovula imathi njengentlama. Iiyunithi zanamhlanje ziqhayisa nge-GPS ekwibhodi erekhoda ubushushu kunye nokubalwa kweepasi ngexesha langempela. Ayinandawo kwaye inkqubo ikhanya ngobomvu; akusekho midlalo yokuqikelela. Ezinye iisayithi zide zisebenzise iirola "ezikrelekrele zokuxinana" ezilungisa ngokuzenzekelayo ubukhulu ngokusekelwe kwimpendulo, ziqinisekisa uxinano olufanayo kulo lonke ububanzi bendlela.
Iipavers zeConcrete Slipform: Xa Amandla Edlula Ukuguquguquka
Iindlela zokuthutha izithuthi eziya kwi-Interstates nakwizikhululo zeenqwelo-moya zithanda i-concrete kuba ihlala amashumi eminyaka. Ii-Slipform pavers zikhupha iribhoni ye-concrete eqhubekayo ngaphandle kweendlela ezizinzileyo, ezikhokelwa zi-laser sensors. Umgangatho wohambo ukhuphisana ne-asphalt, kodwa umphezulu ubonakalisa ubushushu kwaye umelana namatayara agcweleyo. Ukuba wakha wafika kwindawo yokubaleka iinqwelo-moya waza waziva ungafiki, bulela enye yezi zixhobo zibalaseleyo.
Oomatshini Bokugaya: Ukuguqula Okudala Kube Ntsha
Ukwakhiwa ngokutsha okunzulu kubiza kakhulu, ngoko ke abakhi badla “ngokugaya nokuzalisa.” Iiplani ezibandayo ezinencam yedayimani zihlafuna i-asphalt exinzelelweyo ukuya kubunzulu obumiselweyo—ngesiqhelo i-1–4 intshi.—zize ziyithuthe ziye kwiilori ezilindileyo ukuze ziphinde zisetyenziswe. Lo matshini mnye unokwenza imicu yokugungqa okanye iidekhi zebridge ezithambileyo ukuze kuxhathiswe ngcono ukutyibilika. Idrama enye yokugawula inokuthwala ngaphezulu kweebhithi ezingama-300; zitshintshe ngexesha elifanelekileyo kwaye uya kuphepha iphupha elibi lokuqhekeka kweprojekthi phakathi ngexesha lokungxama.
Inkxaso yabaSebenzi: Iiroli ezineTwist, iiLight Towers, kunye neGrunt Work
Nangona abadlali abaphambili befumana udumo, abadlali abaninzi abangaphantsi kwe-radar bagcina umboniso uqhubeka. Abakhulisi beendlela banamathela kwiigreyidi ukuze bolule amahlombe ngaphandle kokwenza umsebenzi owongezelelweyo. Ii-compact track loaders zithutha iipallets zelaphu elenziwe ngeGeo kwiisiseko ezinodaka. Iinqaba ezikhanyayo, ezo zixhaphakileyo "ziibhaluni ezikwintonga," zivumela abasebenzi ukuba bafikelele kwixesha elibekiweyo lokutshintsha ebusuku ngaphandle kokuguqula izithuthi zasekuhlaleni zibe yindawo yokupaka. Kwaye kukho i-plate compactor ethobekileyo; ewe, incinci, kodwa zama ukwakha i-backfill eludongeni ngaphandle kwayo kwaye uya kubona ukuba kutheni abaqhubi beyiphatha njengegolide.
Abagcini beNdalo: Ukunciphisa uthuli kunye neeHybrid Drives
Uxinzelelo olulawulayo luguqula indlela okhethwa ngayo izixhobo. Iziqhoboshelo zokutshiza ngamanzi kwii-crushers zigcina uthuli lwe-silica lungaphantsi kwemida ye-OSHA, ngelixa ii-hybrid pavers zinciphisa ukutshiswa kwepetroli ukuya kuthi ga kwi-15%. Ezinye iinkampani zaseYurophu ngoku zisebenzisa ii-mini-gravators zombane zomsebenzi wokulungisa isixeko—azikhuphi ukukhutshwa kwe-tailpipe, abamelwane abonwabileyo. Lindela ukuba ezi ndlela ziza kufikelela kwi-Atlantic kungekudala; akukho mntu ufuna ukuchazela ibhunga lesixeko isizathu sokuba abantwana abakufutshane nendawo yomsebenzi badinga ii-inhalers.
Ukuhlanganisa Konke: Ukufanisa Umatshini Nomsebenzi
Ukukhetha izixhobo ezifanelekileyo akubandakanyi amandla ehashe kodwa kuxhomekeke kakhulu kwizinto ezifunekayo. Indlela enkulu yasemaphandleni enezithuthi ezimbalwa ingatshintsha i-asphalt paver ngesamente ukuba ilitye lekalika lendawo libiza kancinci. Umsebenzi wasebusuku wasezidolophini unokubangela ukuba oomatshini abancinci bokugaya batsalwe ngaphambi kokuba kuqhutywe umsebenzi kusasa. Yintoni enomdla? Abakhi abaphumeleleyo abanazo nje iimatshini—bazicwangcisa njengeqela laseDaytona.
Ngoko ke kwixesha elizayo xa ujika ujikeleza indawo yokwakha, uya kwazi indlela eyenzeka ngayo le ngxubakaxaka. Ukusuka kwii-motor graders ezicheba umhlaba njenge-bread's blade ukuya kwii-roller ezikrelekrele ezicula xa uxinano lulungile, iyunithi nganye idlala indima. Ukuqonda iintlobo zezixhobo ezisetyenziswa ekwakheni iindlela akupheleli nje ekuneliseni umdla; kunceda iinjineli, ababoneleli, kunye nabahlawuli berhafu babuze imibuzo ekrelekrele—kwaye, ngethemba, bafikelele kwiindlela ezithambileyo ngokukhawuleza.
