Maloboti awiri a Hydrodemolition adamaliza kuchotsa konkire pazipilala m'mabwalo m'masiku a 30, pomwe njira yachikhalidwe ikuyembekezeka kutenga miyezi 8.
Tangoganizani kuyendetsa galimoto mkatikati mwa mzindawo osaona kukula kwa nyumba zowononga ndalama zokwana madola mamiliyoni ambiri chapafupi—palibe magalimoto amene akudutsa ndipo palibe kugwetsa kosokoneza kwa nyumba zozungulira.Izi sizikudziwika m'mizinda ikuluikulu ku United States chifukwa zikusintha komanso kusintha, makamaka pama projekiti akulu.Komabe, kusintha kosawoneka bwino, kwachete kumeneku ndi ndendende zomwe zikuchitika ku Seattle, chifukwa opanga atengera njira yomangira yosiyana: kukulitsa kutsika.
Imodzi mwa nyumba zodziwika bwino ku Seattle, Climate Commitment Arena, ikukonzedwanso kwambiri ndipo malo ake apansi adzapitilira kuwirikiza kawiri.Malowa poyamba ankatchedwa Key Arena ndipo adzakonzedwanso bwino ndikutsegulidwanso kumapeto kwa 2021. Ntchito yokhumbayi inayamba mwalamulo kumapeto kwa 2019 ndipo kuyambira nthawi imeneyo yakhala siteji ya njira zina zapadera zaumisiri ndi zowonongeka.Makontrakitala a Redi Services adachita gawo lalikulu pakusintha pobweretsa zida zatsopanozi pamalowa.
Kukulitsa nyumbayo pansi kumapewa chipwirikiti chomwe chimabwera chifukwa cha kukulitsa kopingasa kwachikhalidwe - kukonzanso kamangidwe ka tawuni ndikugwetsa nyumba zozungulira.Koma njira yapadera imeneyi sichokera ku nkhawa zimenezi.M'malo mwake, kudzoza kumachokera ku chikhumbo ndi ntchito yoteteza denga la nyumbayo.
Wopangidwa ndi katswiri wa zomangamanga Paul Thiry pa Chiwonetsero Chadziko Lonse cha 1962, denga lotsetsereka lodziwika bwino lomwe lidakhala lodziwika bwino kwambiri chifukwa lidagwiritsidwa ntchito poyambira zochitika zakale komanso zachikhalidwe.Chizindikirochi chimafuna kuti zosintha zilizonse za nyumbayi zisungidwe ndi mbiri yakale.
Popeza ndondomeko yokonzanso ikuchitika pansi pa microscope, mbali iliyonse ya ndondomekoyi yakhala ikukonzekera ndi kuyang'anitsitsa.Kukula kutsika-kukulitsa malowa kuchokera pa 368,000 masikweya mapazi kufika pafupifupi 800,000 masikweya mita-kumabweretsa zovuta zosiyanasiyana.Ogwira ntchitoyo anakumbanso mapazi ena 15 pansi pa bwalo lomwe lilipo pano komanso pafupifupi mamita 60 pansi pa msewu.Pokwaniritsa izi, pali vuto laling'ono: momwe mungathandizire mapaundi 44 miliyoni a denga.
Mainjiniya ndi makontrakitala kuphatikiza MA Mortenson Co. ndi subcontractor Rhine Demolition adapanga dongosolo lovuta.Adzachotsa zipilala zomwe zilipo kale ndikuyikapo njira zothandizira kuti zithandizire mamiliyoni a mapaundi a denga, ndiyeno amadalira chithandizo kwa miyezi kuti akhazikitse dongosolo latsopano lothandizira.Izi zingawoneke ngati zovuta, koma kupyolera mwadala ndi kupha pang'onopang'ono, iwo anachita izo.
Woyang'anira projekitiyo adasankha kukhazikitsa njira yothandizira kwakanthawi kuti ithandizire denga lachiwonetsero, la mapaundi mamiliyoni ambiri, ndikuchotsa zipilala zomwe zidalipo kale.Amadalira zothandizira izi kwa miyezi kuti akhazikitse machitidwe atsopano okhazikika.Aquajet poyamba amakumba pansi ndikuchotsa pafupifupi 600,000 cubic metres.kodi.Dothi, ndodo anabowola latsopano maziko thandizo.Dongosolo la zipilala 56 linapanga mawonekedwe apamwamba omwe amagwiritsidwa ntchito pothandizira denga kwakanthawi kuti kontrakitala akhombe kukumba mpaka pamlingo wofunikira.Chotsatira ndicho kugwetsa maziko a konkire oyambirira.
Kwa pulojekiti yowononga kukula kwake ndi kasinthidwe, njira yachikhalidwe ya nyundo ya chisel ikuwoneka ngati yosamveka.Zinatenga masiku angapo kuti agwetse pamanja gawo lililonse, ndipo zinatenga miyezi 8 kuti agwetse mizati yonse 28, mizati 4 yooneka ngati V ndi buttress imodzi.
Kuwonjezera pa kuwonongeka kwachikhalidwe komwe kumatenga nthawi yambiri, njirayi ili ndi vuto lina.Kugwetsa dongosolo kumafuna kulondola kwambiri.Popeza maziko a mapangidwe oyambirira adzagwiritsidwa ntchito ngati maziko a mizati yatsopano, akatswiri amafunikira kuchuluka kwa zipangizo zamapangidwe (kuphatikizapo zitsulo ndi konkire) kuti zikhalebe.Chophwanyira konkire chikhoza kuwononga mipiringidzo yachitsulo ndikuyika chiwopsezo chophwanyira konkriti.
Zolondola komanso zapamwamba zomwe zimafunikira pakukonzanso uku sizikugwirizana ndi njira zachikhalidwe zowononga.Komabe, pali njira ina, yomwe imakhudza njira yomwe anthu ambiri sadziwa.
Kampani yocheperako ya Rheinland Demolition Company idagwiritsa ntchito kulumikizana ndi katswiri wopopera madzi ku Houston Jetstream kuti apeze njira yolondola, yothandiza komanso yothandiza pakugwetsa.Jetstream adalimbikitsa Redi Services, kampani yothandizira mafakitale yochokera ku Lyman, Wyoming.
Yakhazikitsidwa mu 2005, Redi Services ili ndi antchito 500 ndi maofesi ndi masitolo ku Colorado, Nevada, Utah, Idaho ndi Texas.Zopangira ntchito zimaphatikizapo ntchito zowongolera ndi zodzipangira okha, kuzimitsa moto, kukumba ma hydraulic ndi ntchito zovumbula madzimadzi, kuphulika kwa hydraulic, kuthandizira ndi kulumikizana kwa malo, kasamalidwe ka zinyalala, mayendedwe amagalimoto, ntchito zama valve otetezera chitetezo, ndi zina zambiri. Imaperekanso ntchito zamakina ndi zomangamanga kuti zithandizire kupitiriza ntchito yokonza mphamvu.
Redi Services idatsimikizira ntchitoyi ndikuyambitsa loboti ya Aquajet Hydrodemolition pamalo a Climate Commitment Arena.Pofuna kulondola komanso kuchita bwino, kontrakitala adagwiritsa ntchito maloboti awiri a Aqua Cutter 710V.Mothandizidwa ndi 3D poyikira mphamvu mutu, woyendetsa akhoza kufika yopingasa, ofukula ndi pamwamba madera.
"Aka ndi koyamba kuti tigwire ntchito movutikira chonchi," atero a Cody Austin, woyang'anira dera la Redi Services."Chifukwa cha projekiti yathu yam'mbuyomu ya Aquajet loboti, tikukhulupirira kuti ndiyoyenera kugwetsa uku."
Kuti afotokoze zolondola komanso zogwira mtima, womanga nyumbayo adagwiritsa ntchito maloboti awiri a Aquajet Aqua Cutter 710V kugwetsa zipilala 28, ma V-mawonekedwe anayi ndi buttress imodzi mkati mwa masiku 30.Zovuta koma zosatheka.Kuphatikiza pa mawonekedwe owopsa omwe akulendewera pamwamba, vuto lalikulu lomwe makontrakitala onse amakumana nalo pamalopo ndi nthawi.
"Nthawiyi ndi yokhwima kwambiri," adatero Austin."Iyi ndi ntchito yofulumira kwambiri ndipo tikuyenera kulowamo, kugwetsa konkire, ndikusiya ena omwe ali kumbuyo kwathu amalize ntchito yawo kuti akwaniritse kukonzanso monga momwe adakonzera."
Chifukwa aliyense akugwira ntchito yofanana ndikuyesera kumaliza gawo la polojekiti yawo, kukonzekera mwakhama ndi kuyimba mosamala ndikofunikira kuti zonse ziyende bwino ndikupewa ngozi.Makontrakitala odziwika bwino a MA Mortenson Co ali wokonzeka kuthana ndi vutoli.
Munthawi ya projekiti pomwe Redi Services idatenga nawo gawo, makontrakitala okwana 175 ndi ma contract ang'onoang'ono anali pamalopo nthawi imodzi.Chifukwa pali magulu ambiri omwe akugwira ntchito, ndikofunikira kuti mapulani azinthu aziganiziranso za chitetezo cha ogwira ntchito onse ofunikira.Wogwira ntchitoyo adayika malo oletsedwawo ndi tepi yofiira ndi mbendera kuti anthu omwe ali pamalowa azikhala patali kwambiri ndi jeti yamadzi yothamanga kwambiri komanso zinyalala zakuchotsa konkire.
Loboti ya Hydrodemolition imagwiritsa ntchito madzi m'malo mwa mchenga kapena ma jackhammer achikhalidwe kuti apereke njira yofulumira komanso yolondola yochotsera konkire.Dongosolo lowongolera limalola wogwiritsa ntchito kuwongolera kuya ndi kulondola kwa kudula, zomwe ndizofunikira pa ntchito yolondola monga iyi.Mapangidwe apadera komanso osagwedezeka a mipeni ya Aqua amalola kontrakitala kuyeretsa bwino zitsulo zachitsulo popanda kuchititsa ming'alu yaying'ono.
Kuphatikiza pa loboti yokha, Redi Services idagwiritsanso ntchito gawo lina la nsanja kuti likwaniritse kutalika kwa gawolo.Imagwiritsanso ntchito mapampu awiri a Hydroblast othamanga kwambiri kuti apereke kuthamanga kwa madzi kwa 20,000 psi pa liwiro la 45 gpm.Pompoyi ili pamtunda wa 50 kuchokera kuntchito, mamita 100.Agwirizane ndi hoses.
Pazonse, Redi Services idagwetsa ma kiyubiki mita 250.kodi.Zinthu, posunga zitsulo zachitsulo.1 1/2 inchi.Mipiringidzo yachitsulo imayikidwa m'mizere ingapo, ndikuwonjezera zopinga zina kuti zichotsedwe.
"Chifukwa cha zigawo zingapo za rebar, tidayenera kudula mbali zonse zinayi za gawo lililonse," adatero Austin."Ndicho chifukwa chake loboti ya Aquajet ndiye chisankho choyenera.Loboti imatha kudula mpaka 2 mapazi wokhuthala pa pass, zomwe zikutanthauza kuti titha kumaliza mayadi 2 mpaka 3 1/2.Ola lililonse, kutengera kuyika kwa rebar. ”
Njira zowonongeka zowonongeka zidzatulutsa zinyalala zomwe ziyenera kusamaliridwa.Ndi Hydrodemolition, ntchito yoyeretsa imaphatikizapo kuthira madzi komanso kuyeretsa pang'ono.Madzi ophulika amayenera kukonzedwa asanatulutsidwe kapena kubwerezedwa kudzera pampopu yothamanga kwambiri.Redi Services idasankha kubweretsa magalimoto akuluakulu awiri otsekemera okhala ndi makina osefera kuti azikhala ndi kusefa madzi.Madzi osefa amatsitsidwa bwinobwino mupaipi yamadzi amvula pamwamba pa malo omanga.
Chidebe chakale chinasinthidwa kukhala chishango cha mbali zitatu chomwe chinaphwasulidwa kuti chikhale ndi madzi ophulika ndi kuwongolera chitetezo cha malo omangapo otanganidwa.Makina awo osefera amagwiritsa ntchito matanki angapo amadzi ndi kuwunika kwa pH.
"Tinapanga makina athu osefera chifukwa tidachita kale pamasamba ena ndipo tikudziwa bwino zomwe zimachitika," adatero Austin."Maloboti onsewa akamagwira ntchito, tidakonza magaloni 40,000.Kusuntha kulikonse kwa madzi.Tili ndi gulu lachitatu loyang'anira momwe madzi akuwonongeka, omwe amaphatikiza kuyesa pH kuti atsimikizire kuti atayidwa bwino. ”
Redi Services idakumana ndi zopinga ndi zovuta zochepa pantchitoyi.Imalemba gulu la anthu asanu ndi atatu tsiku lililonse, wokhala ndi wogwiritsa ntchito m'modzi pa loboti iliyonse, wogwiritsa ntchito m'modzi pampope iliyonse, m'modzi pagalimoto iliyonse ya vacuum, komanso woyang'anira ndi katswiri wothandizira "magulu" awiri.
Kuchotsa gawo lililonse kumatenga masiku atatu.Ogwira ntchitowo anaika zipangizozo, anathera maola 16 mpaka 20 akugwetsa nyumba iliyonse, kenako n’kusamutsa zipangizozo n’kupita nazo pamndandanda wotsatira.
"Rhine Demolition inapereka chidebe chakale chomwe chinagwiritsidwanso ntchito ndikudulidwa mu zishango za mbali zitatu zomwe zinaphwasulidwa," adatero Austin."Gwiritsani ntchito chofukula ndi chala chachikulu kuti muchotse chivundikiro choteteza, kenako ndikusunthira ku gawo lotsatira.Kusuntha kulikonse kumatenga pafupifupi ola limodzi, kuphatikiza kusuntha chivundikiro choteteza, loboti, kuyimitsa galimoto yochotsa vacuum, kuteteza mapulasitiki otayika, ndi mapaipi osuntha. ”
Kukonzanso bwaloli kunabweretsa anthu ambiri achidwi.Komabe, kuwonongeka kwa ma hydraulic kwa polojekitiyi sikungokopa chidwi cha anthu odutsa, komanso kukopa chidwi cha antchito ena pamalopo.
Chimodzi mwazifukwa zosankhira kuphulika kwa hydraulic ndi mainchesi 1 1/2.Mipiringidzo yachitsulo imayikidwa m'mizere ingapo.Njirayi imalola Redi Services kuyeretsa bwino zitsulo zachitsulo popanda kuchititsa ming'alu yaying'ono mu konkire.Aquajet "anthu ambiri adachita chidwi makamaka tsiku loyamba," adatero Austin."Tinali ndi mainjiniya khumi ndi awiri omwe adabwera kudzawona zomwe zidachitika.Onse anadabwa ndi kuthekera kwa [Aquajet robot] kuchotsa zitsulo ndi kuya kwa madzi kulowa mu konkire.Mwambiri, aliyense anachita chidwi, ndipo ifenso tinachita chidwi..Iyi ndi ntchito yabwino kwambiri. "
Kugwetsa ma hydraulic ndi gawo limodzi lokha la projekiti yayikuluyi.Bwalo la malonjezano a nyengo likadali malo opangira njira zopangira, zatsopano komanso zogwira mtima komanso zida.Pambuyo pochotsa zibowo zoyambira zothandizira, ogwira ntchitowo adalumikizanso denga ndi mizati yothandizira yokhazikika.Amagwiritsa ntchito mafelemu achitsulo ndi konkire kuti apange malo okhala mkati, ndikupitiriza kuwonjezera mfundo zomwe zimasonyeza kutha.
Pa Januware 29, 2021, atapakidwa utoto ndikusainidwa ndi ogwira ntchito yomanga, Climate Promise Arena ndi mamembala a Seattle Krakens, mtengo womaliza wachitsulo udakwezedwa m'malo mwamwambo wakunyumba.
