Mainjiniya nemakondirakiti anosanganisira MA Mortenson Co. uye subcontractor Rhine Demolition vakagadzira chirongwa chakaoma.Vachabvisa mbiru dziripo uye buttresses pavanenge vachiisa tsigiro yekutsigira mamiriyoni emapaundi edenga, uye vobva vavimba nerutsigiro kwemwedzi kuti vaise hurongwa hutsva hwekutsigira.Izvi zvingaita sezvinotyisa, asi kuburikidza nekuita nemaune uye nhanho-ne-nhanho kuuraya, vakazviita.
Maneja wepurojekiti akasarudza kuisa gadziriro yenguva pfupi yekutsigira denga renhandare, matenga emamiriyoni epondo, uku achibvisa mbiru nezvitsigiro.Ivo vanovimba neaya matsigiro kwemwedzi kuti vaise mitsva yekusingaperi masisitimu ekutsigira.Aquajet inotanga kuchera pasi uye inobvisa angangoita 600,000 cubic metres.code.Ivhu, vashandi vakachera nheyo itsva yekutsigira.Iyi 56-pillar system yakagadzira superstructure yakashandiswa kutsigira denga kwenguva kuitira kuti kontrakta inogona kuchera kusvika padanho rinodiwa.Nhanho inotevera inosanganisira kuputsa yekutanga kongiri hwaro.
Kune purojekiti yekuputsa iyi saizi uye kumisikidzwa, iyo yechinyakare chisel sando nzira inoita seisina musoro.Zvakatora mazuva akati wandei kuputsa nemaoko koramu yega yega, uye zvakatora mwedzi misere kuputsa makoramu ese makumi maviri nemasere, makoramu mana akaenzana neV uye imwe buttress.
Mukuwedzera kune kuparara kwechinyakare kunotora nguva yakawanda, nzira iyi ine imwe inogona kukanganisa.Kubvisa chimiro kunoda kurongeka kwakanyanya.Sezvo hwaro hwechimiro chepakutanga huchashandiswa sehwaro hwembiru itsva, mainjiniya anoda humwe huwandu hwezvigadzirwa zvemaumbirwo (kusanganisira simbi nekongiri) kuti zvirambe zvakadaro.Iyo kongiri inopwanya inogona kukuvadza simbi mbariro uye njodzi micro-kutsemuka kongiri mbiru.
Kurongeka uye kutsanangurwa kwepamusoro-soro kunodiwa pakugadziridza uku hakuenderane nemaitiro echinyakare ekuparadza.Zvisinei, pane imwe sarudzo, iyo inosanganisira nzira iyo vanhu vakawanda vasingazivi nayo.
Iyo subcontractor Rheinland Demolition Company yakashandisa kusangana neHouston mvura yekupfapfaidza nyanzvi Jetstream kutsvaga chaiyo, inoshanda uye inoshanda mhinduro yekuparadza.Jetstream yakakurudzira Redi Services, kambani yekutsigira basa reindasitiri yakavakirwa muLyman, Wyoming.
Yakatangwa muna 2005, Redi Services ine vashandi mazana mashanu nemahofisi nezvitoro muColorado, Nevada, Utah, Idaho neTexas.Zvigadzirwa zvesevhisi zvinosanganisira kutonga uye otomatiki masevhisi, kudzima moto, kuchera hydraulic uye fluid vacuum masevhisi, hydraulic blasting, nzvimbo inochinja yekutsigira uye kurongeka, manejimendi emarara, kutakura marori, kumanikidza kuchengetedza mavharuvhu masevhisi, nezvimwe. Inopawo michina uye mabasa ekuvaka ehurumende kusimudzira. kuenderera mberi kwekuchengetedza sevhisi kugona.
Redi Services yakaratidza basa iri uye yakaunza Aquajet Hydrodemolition robhoti kunzvimbo yeClimate Commitment Arena saiti.Nekurongeka uye kushanda nesimba, kondirakiti akashandisa marobhoti maviri eAqua Cutter 710V.Nerubatsiro rwe 3D yekumisikidza musoro wesimba, mushandisi anogona kusvika kune yakachinjika, yakatwasuka uye nepamusoro nzvimbo.
"Aka ndekekutanga kushanda pasi pechimiro chinorema kudaro," akadaro Cody Austin, maneja wedunhu reRedi Services."Nekuda kwepurojekiti yedu yeAquajet robhoti, tinotenda kuti yakakodzera kuparadzwa uku."
Kuti zvive nemazvo uye nemazvo, mugadziri akashandisa marobhoti maviri eAquajet Aqua Cutter 710V kuputsa dzimwe mbiru makumi maviri nemasere, maV-maumbirwo mana uye buttress imwe mukati memazuva makumi matatu.Zvinonetsa asi zvisingaite.Pamusoro pechimiro chinotyisa chakarembera pamusoro, dambudziko guru rinotarisana nevese makondirakiti pasaiti inguva.
"Nguva yacho yakasimba," Austin akadaro.“Iri ibasa riri kukurumidza kukurumidza uye tinofanira kupindamo, topwanya kongiri, torega vamwe vari shure kwedu vapedze basa ravo kuitira kuti vagadzirise sezvavakaronga.”
Nekuti munhu wese ari kushanda mundima imwechete uye achiedza kupedzisa chikamu chepurojekiti yavo, kuronga zvine hunyanzvi uye kurongeka kwakanyatso kudiwa kuti zvese zvifambe zvakanaka uye kudzivirira tsaona.Iye anozivikanwa kondirakiti MA Mortenson Co akagadzirira kusangana nedambudziko.
Munguva yechikamu chepurojekiti apo Redi Services yakatora chikamu, vanosvika zana nemakumi manomwe nevashanu vekondirakiti nevadiki vaive panzvimbo panguva imwe chete.Nekuti kune huwandu hukuru hwezvikwata zviri kushanda, zvakakosha kuti kuronga zvinhu kutarisewo kuchengetedzeka kwevashandi vese vakakodzera.Kondirakiti yakamaka nzvimbo yakarambidzwa nematepi matsvuku uye mireza kuchengetedza vanhu vari panzvimbo yakachengeteka chinhambwe kubva kune yakakwirira-inomanikidza mvura jet uye marara kubva pakubvisa kongiri.
Robhoti reHydrodemolition rinoshandisa mvura pachinzvimbo chejecha kana nhando dzechinyakare kupa nzira inokurumidza uye yakarurama yekubvisa kongiri.Iyo yekudzora sisitimu inobvumira mushandisi kudzora kudzika uye kurongeka kwekucheka, izvo zvakakosha kune chaiyo basa seizvi.Iyo yakasarudzika dhizaini uye isina vibration-isina mapanga eAqua inobvumira kontrakta kunyatsochenesa masimbi esimbi pasina kukonzera diki-diki.
Pamusoro peiyo robhoti pachayo, Redi Services yakashandisawo imwe shongwe chikamu kugarisa kureba kwekoramu.Inoshandisawo mapombi maviri eHydroblast high-pressure water pumps kuti ape mvura inomanikidzwa ye20,000 psi pakukurumidza kwe45 gpm.Iyo pombi inowanikwa 50 tsoka kubva kubasa, 100 tsoka.Vabatanidze nehosi.
Pakazara, Redi Services yakaputsa 250 cubic metres yechimiro.code.Material, uchichengeta simbi dzesimbi dzakasimba.1 1/2 inches.Mazariro esimbi akaiswa mumitsara yakawanda, achiwedzera zvimwe zvipingamupinyi pakubvisa.
"Nekuda kwematanho akawanda erebar, taifanira kucheka kubva kumativi mana ekoramu yega yega," Austin akadaro.“Ndosaka robhoti yeAquajet iriyo sarudzo yakanaka.Robhoti rinogona kucheka kusvika 2 tsoka dzakakora papfuura, zvinoreva kuti tinokwanisa kupedza 2 kusvika 3 1/2 mayadhi.Nguva nenguva, zvichienderana nekuiswa kwe rebar."
Nzira dzakajairwa dzekupwanya dzinoburitsa marara anoda kutarisirwa.NeHydrodemolition, basa rekuchenesa rinosanganisira kurapwa kwemvura uye kushomeka kwekuchenesa zvinhu.Mvura inoputika inoda kucheneswa isati yaburitswa kana kutenderedzwazve kuburikidza nepombi ine simba guru.Redi Services yakasarudza kuunza marori maviri makuru evacuum ane kusefa masisitimu kuti ave nekusefa mvura.Mvura yakasvibiswa inobudiswa zvakachengeteka mupombi yemvura inonaya iri pamusoro penzvimbo yekuvaka.
Chigaba chekare chakachinjwa kuva nhovo ine mativi matatu yakabviswa kuti igova nemvura inoputika uye kunatsiridza chengeteko yenzvimbo yokuvaka yakabatikana.Yavo yefiltration system inoshandisa akatevedzana matangi emvura uye pH yekutarisa.
"Takagadzira yedu filtration system nekuti takazviita pane mamwe mawebhusaiti kare uye isu tinoziva maitiro," akadaro Austin.“Apo marobhoti ese ari kushanda, takagadzira marita 40,000.Imwe neimwe shanduko yemvura.Isu tine bato rechitatu rekutarisa zvakatipoteredza zvemvura yakasviba, izvo zvinosanganisira kuyedza pH kuti ive nechokwadi chekuraswa kwakachengeteka.
