Imashini ebyiri za Hydrodemolition zarangije gukuraho beto mu nkingi yikibuga mu minsi 30, mugihe uburyo gakondo buteganijwe gufata amezi 8.
Tekereza utwaye imodoka mu mujyi rwagati utabonye inyubako ya miriyoni y'amadorari yagutse hafi - nta muhanda uyobora cyangwa nta gusenya guhungabanya inyubako zikikije. Ibi bintu ntibisanzwe byunvikana mumijyi minini yo muri Amerika kuko bihora bitera imbere kandi bigahinduka, cyane cyane kubikorwa byubunini. Nyamara, iyi nzibacyuho yoroheje, ituje nibyo rwose bibera mumujyi wa Seattle, kuberako abitezimbere bakoresheje ubundi buryo bwo kubaka: kwaguka kumanuka.
Imwe mu nyubako zizwi cyane za Seattle, Arena Climate Commitment Arena, irimo kuvugururwa cyane kandi ubuso bwayo buzikuba kabiri. Ikibanza cyahoze cyitwa Key Arena kikaba kizavugururwa kandi kizongera gufungurwa mu mpera za 2021.Uyu mushinga ukomeye watangiye kumugaragaro mu mpeshyi ya 2019 kandi kuva icyo gihe wabaye intambwe yuburyo bwihariye bwo kubaka no gusenya. Rwiyemezamirimo Redi Services yagize uruhare runini mugikorwa cyo guhindura ibintu azana ibi bikoresho bishya kurubuga.
Kwagura inyubako hepfo birinda akaduruvayo katewe no kwaguka kwa gakondo gakondo - guhindura imiterere yimijyi no gusenya inyubako zikikije. Ariko ubu buryo budasanzwe ntabwo bukomoka kuri izi mpungenge. Ahubwo, guhumeka biva mubyifuzo ninshingano zo kurinda igisenge cyinyubako.
Igishushanyo mbonera cyubatswe na Paul Thiry mu imurikagurisha ry’isi ryo mu 1962, igisenge cyamenyekanye ku buryo bworoshye cyabonye umwanya w’amateka kuko cyakoreshwaga mu mateka n’umuco. Ikimenyetso cyihariye gisaba ko impinduka zose zinyubako zigumana ibintu bigize imiterere yamateka.
Kuva gahunda yo kuvugurura ikorwa munsi ya microscope, buri kintu cyose cyakozwe cyateguwe kandi kigenzurwa. Kwiyongera kumanuka-kongera ubuso kuva kuri metero kare 368.000 kugera kuri metero kare 800.000-byerekana ibibazo bitandukanye byo gutanga ibikoresho. Abakozi bacukuye indi metero 15 munsi yikibuga cyubu na metero 60 munsi yumuhanda. Mugihe urangije iki gikorwa, haracyari ikibazo gito: uburyo bwo gutera inkunga miliyoni 44 zama pound.
Ba injeniyeri naba rwiyemezamirimo barimo MA Mortenson Co hamwe naba rwiyemezamirimo Rhine Demolition bakoze gahunda igoye. Bazakuraho inkingi na buttres zihari mugihe bashiraho sisitemu yo gushyigikira miriyoni yama pound yinzu, hanyuma bakishingikiriza kumfashanyo yamezi yo gushiraho sisitemu nshya yo gushyigikira. Ibi birasa nkaho bitoroshye, ariko binyuze muburyo nkana no gukora intambwe ku yindi, barabikoze.
Umuyobozi wumushinga yahisemo gushiraho sisitemu yingoboka yigihe gito kugirango ishyigikire ikibuga cyikigereranyo, miriyoni nyinshi zama pound, mugihe ukuraho inkingi na buto. Bishingikiriza kuri izi nkunga amezi kugirango bashireho sisitemu nshya ihoraho. Aquajet ibanza gucukura ikuraho metero kibe 600.000. kode. Ubutaka, abakozi bacukuye inkunga nshya. Sisitemu 56 yinkingi yashyizeho superstructure yakoreshejwe mugushigikira by'agateganyo igisenge kugirango rwiyemezamirimo ashobore gucukura kurwego rukenewe. Intambwe ikurikira irimo gusenya fondasiyo yumwimerere.
Kubikorwa byo gusenya ingano nubunini, uburyo gakondo bwa chisel inyundo bisa nkaho bidasobanutse. Byatwaye iminsi itari mike gusenya intoki buri nkingi, kandi byafashe amezi 8 yo gusenya inkingi 28 zose, inkingi 4 zimeze nka V na buttre imwe.
Usibye gusenya gakondo bifata igihe kinini, ubu buryo bufite izindi ngaruka mbi. Gusenya imiterere bisaba ibisobanuro bihanitse cyane. Kubera ko urufatiro rwimiterere yumwimerere ruzakoreshwa nkishingiro ryinkingi nshya, abashakashatsi bakeneye umubare munini wibikoresho byubaka (harimo ibyuma na beto) kugirango bikomeze kuba byiza. Crusher ya beto irashobora kwangiza ibyuma byibyuma kandi bigatera micro-gucamo inkingi ya beto.
Ibisobanuro nukuri kurwego rwo hejuru bisabwa muri iri vugurura ntabwo bihuye nuburyo gakondo bwo gusenya. Ariko, hariho ubundi buryo, burimo inzira abantu benshi batamenyereye.
Isosiyete ikora ibijyanye no gusenya Rheinland yo gusenya yakoresheje umubonano n’inzobere mu gutera amazi ya Houston Jetstream kugira ngo ibone igisubizo nyacyo, cyiza kandi cyiza cyo gusenya. Jetstream yasabye Redi Services, isosiyete itera inkunga inganda zifite icyicaro i Lyman, Wyoming.
Redi Services yashinzwe mu 2005, ifite abakozi 500 n'ibiro n'amaduka muri Colorado, Nevada, Utah, Idaho na Texas. Ibicuruzwa bya serivisi birimo serivisi zo kugenzura no gukoresha ibyuma, kuzimya umuriro, gucukura hydraulic na serivisi ziva mu mazi, guturika hydraulic, gutera inkunga ibikoresho no guhuza ibikorwa, gucunga imyanda, gutwara amakamyo, serivisi z’umutekano w’umuvuduko, n'ibindi. ubushobozi bwa serivisi zihoraho.
Serivise ya Redi yerekanye iki gikorwa kandi imenyekanisha robot ya Aquajet Hydrodemolition kurubuga rwa Climate Commitment Arena. Kugirango ubashe gukora neza, rwiyemezamirimo yakoresheje robot ebyiri za Aqua Cutter 710V. Hamwe nubufasha bwa 3D umwanya wimbaraga umutwe, uyikoresha arashobora kugera kuri horizontal, vertical and overhead areas.
Umuyobozi w'akarere ka Redi Services, Cody Austin yagize ati: "Ni ubwa mbere dukora mu nzego ziremereye." Ati: “Kubera umushinga wa robot wa kera wa Aquajet, twizera ko ukwiye cyane gusenywa.”
Kugirango bisobanuke neza kandi neza, rwiyemezamirimo yakoresheje robot ebyiri za Aquajet Aqua Cutter 710V kugirango asenye inkingi zigera kuri 28, V-shusho enye na buttre imwe muminsi 30. Ingorabahizi ariko ntibishoboka. Usibye imiterere iteye ubwoba yimanitse hejuru, ikibazo gikomeye abashoramari bose bahura nacyo kurubuga ni igihe.
Austin yagize ati: “Ingengabihe irakomeye cyane. Ati: "Uyu ni umushinga wihuta cyane kandi tugomba kujyayo, gusenya beto, no kureka abandi bari inyuma yacu bakarangiza imirimo yabo kugira ngo bakore ivugurura nk'uko byari byateganijwe."
Kuberako buriwese akora mumurima umwe kandi akagerageza kurangiza igice cyumushinga we, birasabwa gutegurana umwete hamwe na orchestre yitonze birasabwa kugirango ibintu byose bigende neza kandi birinde impanuka. Rwiyemezamirimo uzwi cyane MA Mortenson Co yiteguye guhangana n'ikibazo.
Mugihe cyumushinga aho Redi Services yitabiriye, abashoramari naba rwiyemezamirimo bagera kuri 175 bari kurubuga icyarimwe. Kuberako hari umubare munini wamakipe akora, ni ngombwa ko igenamigambi ryibikoresho naryo ryita kumutekano w'abakozi bose bireba. Rwiyemezamirimo yashyizeho akarere kabujijwe hamwe na kaseti itukura hamwe n’ibendera kugira ngo abantu babe ku kibanza kiri kure y’indege y’amazi y’umuvuduko ukabije n’imyanda iva mu nzira yo gukuraho beto.
Imashini ya Hydrodemolition ikoresha amazi aho gukoresha umucanga cyangwa jackhammers gakondo kugirango itange uburyo bwihuse kandi bwuzuye bwo gukuraho beto. Sisitemu yo kugenzura yemerera uyikoresha kugenzura ubujyakuzimu nukuri gukata, ni ngombwa kubikorwa byuzuye nkibi. Igishushanyo kidasanzwe hamwe no kunyeganyega bitarimo ibyuma bya Aqua bituma rwiyemezamirimo asukura neza ibyuma bitarinze gutera mikoro.
Usibye robot ubwayo, Redi Services yanakoresheje igice cyumunara wongeyeho uburebure bwinkingi. Ikoresha kandi pompe ebyiri zamazi ya Hydroblast kugirango itange umuvuduko wamazi wa 20.000 psi kumuvuduko wa 45 gpm. Pompe iherereye kuri metero 50 uvuye kukazi, metero 100. Huza na hose.
Muri rusange, Redi Services yasenye metero kibe 250 zubatswe. kode. Ibikoresho, mugihe ugumisha ibyuma. 1/2. Ibyuma byuma byashyizwe mumirongo myinshi, wongeyeho inzitizi zo gukuraho.
Austin yagize ati: "Kubera ibice byinshi bya rebar, twagombaga guca ku mpande enye zose za buri nkingi." Ati: “Niyo mpamvu robot ya Aquajet ari amahitamo meza. Robo irashobora guca kuri metero 2 z'ubugari kuri pass, bivuze ko dushobora kuzuza metero 2 kugeza 3/2. Buri saha, bitewe n'ahantu hashyirwa. ”
Uburyo busanzwe bwo gusenya buzatanga imyanda igomba gucungwa. Hamwe na Hydrodemolition, umurimo wo gukora isuku urimo gutunganya amazi no gusukura ibintu bike kumubiri. Amazi yaturika agomba gutunganywa mbere yuko asohoka cyangwa akazenguruka binyuze muri pompe yumuvuduko mwinshi. Serivisi za Redi zahisemo kumenyekanisha amakamyo abiri manini ya vacuum hamwe na sisitemu yo kuyungurura kugirango ibemo kandi iyungurura amazi. Amazi yungurujwe asohoka neza mumiyoboro yamazi yimvura hejuru yubwubatsi.
Ikonteneri ishaje yahinduwe inkinzo yimpande eshatu yashenywe kugirango ibemo amazi aturika kandi bitezimbere umutekano wubwubatsi bwuzuye. Sisitemu yabo yo kuyungurura ikoresha urukurikirane rw'ibigega by'amazi no gukurikirana pH.
Austin yagize ati: "Twateje imbere sisitemu yo kuyungurura kuko twabikoze ku zindi mbuga mbere kandi tumenyereye inzira." Ati: “Iyo robo zombi zakoraga, twatunganyaga litiro 40.000. Buri cyerekezo cy'amazi. Dufite undi muntu wa gatatu wo gukurikirana ibidukikije by’amazi y’amazi, harimo no gupima pH kugira ngo yandurwe neza. ”
Serivisi za Redi zahuye nimbogamizi nke nibibazo mumushinga. Ikoresha itsinda ryabantu umunani burimunsi, hamwe numukoresha umwe kuri buri robot, umukoresha umwe kuri buri pompe, umwe kuri buri kamyo ya vacuum, hamwe numuyobozi numu technicien kugirango bashyigikire “amakipe” abiri.
Gukuraho buri nkingi bifata iminsi itatu. Abakozi bashizeho ibikoresho, bamara amasaha 16 kugeza kuri 20 basenya buri nyubako, hanyuma bimura ibikoresho kumurongo ukurikira.
Austin yagize ati: "Rhine Demolition yatanze kontineri ishaje yongeye gukoreshwa igabanywa mu nkinzo z'impande eshatu zashenywe." “Koresha imashini ikora igikumwe kugirango ukureho igifuniko gikingira, hanyuma wimuke ku nkingi ikurikira. Buri rugendo rutwara isaha imwe, harimo kwimura igifuniko gikingira, robot, gushyiraho ikamyo ya vacuum, kwirinda plastike yamenetse, hamwe n’amazu yimuka. ”
Kuvugurura stade byazanye amatsiko menshi abareba. Icyakora, gusenya hydraulic gusenya umushinga ntabwo byashimishije abahisi gusa, ahubwo byanashimishije abandi bakozi kurubuga.
Imwe mumpamvu zo guhitamo hydraulic guturika ni 1/2 santimetero. Ibyuma byuma byashyizwe mumirongo myinshi. Ubu buryo butuma serivisi za Redi zisukura neza ibyuma bitarinze gutera micro-ibice muri beto. Austin yagize ati: “Aquajet“ abantu benshi bashimishijwe-cyane cyane ku munsi wa mbere. ” Ati: “Twari dufite injeniyeri n'abagenzuzi icumi baza kureba uko byagenze. Bose batunguwe n'ubushobozi bwa [Aquajet robot] bwo gukuraho ibyuma n'ubujyakuzimu bw'amazi yinjira muri beto. Muri rusange, abantu bose baratangaye, natwe natwe. . Aka ni akazi keza. ”
Gusenya Hydraulic nikintu kimwe gusa cyuyu mushinga munini wo kwagura. Ikibuga cy’imihindagurikire y’ikirere gikomeje kuba ahantu ho guhanga, guhanga udushya kandi neza. Nyuma yo gukuraho ibyuma byumwimerere byabakozi, abakozi bongeye guhuza igisenge kumurongo uhoraho. Bakoresha ibyuma na beto kugirango bagire aho bicara imbere, kandi bakomeza kongeramo ibisobanuro byerekana kurangiza.
Ku ya 29 Mutarama 2021, nyuma yo gusiga irangi no gushyirwaho umukono n’abakozi bo mu bwubatsi, Ikirere cy’Isezerano ry’ikirere hamwe n’abanyamuryango ba Seattle Krakens, urumuri rwa nyuma rw’icyuma rwazamuwe mu muhango wo gusakara.
