Iirobhothi ezimbini ze-hydrodemolication zigqibe ukususwa kwekhonkrithi ezivela kwi-irena pillars ngeentsuku ezingama-30, ngelixa indlela yemveli iqikelelwa ukuthatha iinyanga ezisi-8.
Khawufane ucinge ukuba uqhuba kwiZiko leSixeko ngaphandle kokukhula kolwandiso lwe-Multimention-Ralrillion-Ralrillion SanOR kufutshane-Akukho trafired trafied kunye nokudilizwa okuphazamisekileyo kwezakhiwo ezingqongileyo. Le meko iphantse imanyazi kwezona dolophu zinkulu eUnited States kuba zihlala zivela kwaye zitshintsha, ngakumbi iiprojekthi zobungakanani. Nangona kunjalo, okuguqukayo, inguqulelo ethe cwaka yile nto yenzekayo kwi-DownTown Seattle, kuba abaphuhlisi bamkele indlela eyahlukileyo yokwakha: ukwanda ezantsi.
Enye yezakhiwo ezidumileyo zeSeattle, i-Isna yokuzibophelela kwemozulu, ihlaziya ireniso kunye nendawo yalo yomgangatho ongaphezulu. Indawo leyo yayibizwa ngokuba yi-Arena kwaye iya kuhlaziywa ngokupheleleyo kwaye iphinde iphinde iphinde iphinde emva kwe-2021. Iinkonzo zeKontraktha Iinkonzo zidlale indima ephambili kwinkqubo yenguqu ngokuzisa ezi zixhobo zinobuchule kwisiza.
Ukwandisa isakhiwo ezantsi kuyakukuphepha isiphithiphithi esibangelwe kukwandiswa okuthe tyaba ngokwesiko Kodwa le ndlela yodwa ayiyonto ingekho ngaphandle kwezi zinto zixhalabisayo. Endaweni yoko, inkuthazo ivela kumnqweno nakwimishini yokukhusela uphahla lwesakhiwo.
Yenziwe ngumntu oliyilayo u-Paul th Isupotion yeHlabathi ye-1962, uphahla olubonakalayo olubonakalayo lufumene imeko yophawu lwembali ngoba lwalusesimo sembali ngoba lwalusetyenziselwa iminyhadala yembali nezenkcubeko. Ukhetho lwemihlaba lomhlaba kufuna ukuba naluphi na uhlengahlengiso kwisakhiwo lugcina izinto zembali.
Kuba inkqubo yokufihla iqhutywa phantsi kwemakroskopu, yonke inkalo yenkqubo iye yavavanywa kunye nokuhlolwa. Ukwanda ezantsi -nda-ukwandisa indawo ukusuka kwi-368,000 yeenyawo ukuya kuthi ga kwi-800,000 yeenyawo ubude beemitha ezahlukeneyo. Iqela labasebenzi bemba ezinye iinyawo ezili-15 ngaphantsi komgangatho wangoku umgangatho we-Adna kwaye malunga neenyawo ezingama-60 ngaphantsi kwesitrato. Ngelixa iphumeza le fean, kusekho ingxaki encinci: indlela yokuxhasa izigidi ezingama-44 ezizigidi zophahla.
Iinjineli kunye neekontraki kubandakanywa ne-Maenswoaddon Co. kunye ne-subcontractor Rhine demolication iphuhlise isicwangciso esinzima. Baza kususa iikholamu ezikhoyo kwaye bathambekele ngelixa befaka inkqubo yenkxaso ukuxhasa izigidi zeendidi zophahla, emva koko baxhomekeke kwinkxaso kwiinyanga zenkxaso. Oku kunokubonakala kuyinkqixa, kodwa kwindlela yokuhlisela ngabom kunye nokuphunyezwa ngamanyathelo ngamanyathelo, bakwenza oko.
Umphathi weProjekthi wakhetha ukufaka inkqubo yenkxaso yethutyana ukuxhasa i-iconic iconic i-Isna's iconic, ephahlani le-pound, ngelixa ususa iintsika ezikhoyo kunye ne-tube. Baxhomekeke kwezi nkxaso kwiinyanga zokufaka iinkqubo ezintsha zenkxaso esisigxina. I-AquaJet iqale yehla kwaye isusa malunga neemitha ezingama-600,000. ikhowudi. Umhlaba, abasebenzi bayayixhasa inkxaso yesiseko entsha. Le nkqubo yentsika ye-56 ye-Pilar yadala i-upersset esetyenziselwa ukuxhasa okwethutyana uphahla ukuze i-contractor inokumba kwinqanaba elifanelekileyo. Inyathelo elilandelayo libandakanya ukupholisa isiseko sekhonkrithi sokuqala.
Kwiprojekthi yokuphazamiseka kolu bukhulu kunye noqwalaselo, indlela yendam ye-chisel hammer ibonakala ingenangqondo. Kuthathe iintsuku ezininzi ukudiliza ngesandla kwikholamu nganye, kwaye kuthatha iinyanga ezisi-8 ukuthoba zonke iikholamu ezingama-28, iikholamu ezi-4 ze-4 v-vamds kunye ne-buttress enye.
Ukongeza kokupheliswa kwendalo okuthatha ixesha elininzi, le ndlela inenye into enokubakho. Ukuchitha ulwakhiwo kufuna ukubakho okungaphezulu. Kuba isiseko sobume obuqu siza kusetyenziswa njengesiseko seentsika ezintsha, iinjineli zifuna inani elithile lezinto ezizezinye (kubandakanya intsimbi kunye nekhonkrithi) ukuya kuhlala kunjalo. Ikhonkrithi yekhonkrithi inokuyonakalisa imivalo yentsimbi kunye nokubeka umngcipheko wokomeleza ikholam yekhonkrithi.
Ukuchaneka kwenqanaba eliphezulu elifunekayo koku kulungiswa ngokungahambelani neendlela zokudilizwa kwemveli. Nangona kunjalo, kukho ukhetho olwahlukileyo, olubandakanya inkqubo abantu abaninzi bengaqhelanga.
Inkampani ye-subcontractor riolical Rheinland yaseRheinalland isebenzise unxibelelwano ne-Houston Goreck Spray Getstream ukufumana isisombululo esichanekileyo, esifanelekileyo nesifanelekileyo sokudilizwa. I-JetStrem icetyiswa iinkonzo ze-redi, inkampani yenkxaso yenkonzo yenkonzo esekwe eLyman, Wyoming.
Ukusekwa ngo-2005, iinkonzo ze-redi inabasebenzi abangama-500 kunye neeofisi kunye neevenkile eColorado, Nevada, i-Utah, i-Idaho kunye neTexas. Iimveliso zenkonzo zibandakanya iinkonzo zolawulo nezenzekelayo, ukucima umlilo, ukugxothwa kwe-hydraulic kunye neenkonzo ze-hydrauli, inkxaso ye-valdraver, i-HodDratic Claring, iZithuthi, ukuThengisa, iRhafu yeVenkile yokuphucula Izakhono eziqhubekayo zenkonzo yesondlo.
Iinkonzo ze-Redi zibonisa lo msebenzi kwaye wazisa i-robhothi ye-robhothi ye-robhothi ye-robot yokwenza umbulelo wemozulu. Ukuchaneka nokusebenza kakuhle, iKontraktha isebenzise i-710v Robots. Ngoncedo lweNtloko ye-3D yokubeka iNtloko ye-3D, umqhubi unokufikelela kwiindawo ezithe tyaba, ezithe nkqo kwaye ngaphezulu.
"Eli lixesha lokuqala sisebenze phantsi kwesakhiwo esinzima," utshilo uCody Austin, uMphathi weNgingqi weeNkonzo zeRedin. "Ngenxa yeprojekthi yethu yerobhothi ye-Aquajot, siyakholelwa ukuba kufanelekile oko."
Ukuze ichaneke kwaye isebenze ngokufanelekileyo, ikhontraktha isebenzise i-AquaJet ezimbini ze-AquaJet i-Aqua Cutter 710v Iirobhothi zokuphelisa iintsika ezingama-28, iimilo ezine v kunye ne-butress enye ngaphakathi kweentsuku ezingama-30. Umngeni kodwa awunakwenzeka. Ukongeza kwisakhiwo esoyikisayo esixhonywe ngaphezulu, owona mceli mngeni omkhulu kubo bonke oontskisha kwindawo yexesha.
"Ithayimthebhile ingqongqo kakhulu," utshilo uAustin. "Le yiprojekthi esele ikhawulelwe kakhulu kwaye kufuneka singene apho, sidilize ikhonkrithi, kwaye bayeke abanye abasemva kokugqiba kwakhe bagqibe umsebenzi wabo ukuze basebenze."
Kuba wonke umntu usebenza kwintsimi enye kwaye uzama ukugqiba inxalenye yeprojekthi yabo, ucwangciso lokukhuthala kunye nokucwangciswa ngononophelo kuyafuneka ukugcina yonke into iqhuba kakuhle kwaye ithintele ingozi. Ikhontraktha eyaziwayo Manueson Counsdon CO. ikulungele ukudibana nocelomngeni.
Ngexesha lesiGaba seProjekthi apho iinkonzo ze-redi zithathe inxaxheba kwiikhontrakthi ezili-175 kunye neekontraki ezi-175 kunye nabaphathi bendawo ngexesha elinye. Kuba kukho inani elikhulu lamaqela, kubalulekile ukuba ukucwangciswa kwezinto kuqwalasele ukhuseleko lwabo bonke abasebenzi abachaphazelekayo. Ikhontraktha iphawula indawo enesithintelo nge-Red Tape kunye neeflegi ukugcina abantu kwindawo leyo kumgama okhuselekileyo ukusuka kwijethi yamanzi e-jet kunye nenkunkuma kwiNkqubo yokuShuma kwekhonkrithi.
I-hydrodemolication irobhothi isebenzisa amanzi endaweni yesanti okanye i-jackshamed yemveli yokubonelela ngendlela ebonakalayo nechanekileyo yekhonkrithi. Inkqubo yolawulo ivumela umqhubi ukuba alawule ubunzulu nangokuchaneka kwesikithi, esibalulekileyo kumsebenzi ochanekileyo ngolu hlobo. Uyilo olwahlukileyo kunye ne-viction-ngaphandle kwe-Aqua ivumela iKontraktha icoceke ngokupheleleyo imivalo yentsimbi ngaphandle kokubangela imicro-rocks.
Ukongeza kwirobhothi ngokwayo, iinkonzo ze-redi nazo zikwasebenzisa icandelo leNceba leNdoda yokulungiselela ukuphakama kwekholamu. Ikwasebenzisa impompo ezimbini zoxinzelelo lwe-hydroblast ukubonelela ngoxinzelelo lwamanzi angama-20,000 psi ngesantya esingama-45 i-GPM. Impompo ifumaneka iinyawo ezingama-50 zomsebenzi, iinyawo ezili-100. Dibanisa ne-hoses.
Iyonke, iinkonzo ze-redi zidilize iimitha ezingama-250 ze-cuic. ikhowudi. Izinto, ngelixa ugcina imivalo yentsimbi. I-1 1/2 i-intshi. Imivalo yentsimbi ifakwe kwimiqolo emininzi, yongeza imiqobo eyongezelelweyo yokususwa.
"Ngenxa yamanxuwa amaninzi okhubazekile, kwafuneka sisike kuwo onke amacala amane kwikholamu nganye," Austin watshoyo. Yiyo loo nto i-aquaJet irobhothi lukhetho olufanelekileyo. Irobhothi inokusika ukuya kwi-2 yeenyawo ezinobunkunkqele kwipass nganye, oko kuthetha ukuba singayigqiba i-2 ukuya kwi-3/2 iiyadi. Ngeyure, kuxhomekeka kwindawo yophando. "
Iindlela zokudiliza eziqhelekileyo ziya kuvelisa inkunkuma ekufuneka ilawulwa. Ngomsebenzi we-hydrodemolide, umsebenzi wokucoca ubandakanya unyango lwamanzi kunye nokucocwa komzimba okuncinci. Amanzi avuthayo kufuneka aphathwe ngaphambi kokuba akhutshelwe okanye aphinde abuyele kwimpompo yoxinzelelo oluphezulu. Iinkonzo ze-redi ikhethe ukwazisa iilori ezimbini ezinkulu ze-vacuum ngeenkqubo zokuziqhelanisa nokuqulatha kwaye zicoce amanzi. Amanzi atyhidiweyo akhutshelwe ngokukhuselekileyo kumbhobho wamanzi emvula ngaphezulu kwendawo yokwakha.
Isikhongozeli sakudala siguqulwe saba yikhaka eliya kuba sisiseko esikwisithathu esakhutshiwe ukuba siqulathe amanzi aqhumayo kunye nokuphucula ukhuseleko lwendawo yokwakha exakekileyo. Inkqubo yabo yokuqulunqa isebenzisa uthotho lweetanki zamanzi kunye nokubeka iliso.
"Siphuhlise inkqubo yethu yokufihlakeleyo kuba siyenzile kwezinye iisayithi ngaphambi kwaye siyayazi inkqubo," Austin ichaza ngaphandle. "Xa zombini iirobhothi bezisebenza, sisenza iilitha ezingama-40,000. Utshintsho lwamanzi ngalunye. Sinomntu wesithathu ukubeka iliso kwimiba yokusingqongileyo yamanzi amdaka, equka ukuvavanya i-PH ukuqinisekisa ukhuseleko olukhuselekileyo. "
Iinkonzo ze-redi ihlangabezane nezithintelo kunye neengxaki kwiprojekthi. Isebenzisa iqela labantu abasibhozo yonke imihla, umqhubi omnye kwi-robhothi nganye, umqhubi omnye kwimpompo nganye, kunye nesuphavayiza nganye ye-vacuum "kunye nengcali ye-robot". "
Ukususwa kwekholamu nganye kuthatha malunga neentsuku ezintathu. Abasebenzi bafake izixhobo, bachitha iiyure ezili-16 ukuya kwezi-20 ezibeka isakhiwo ngasinye, emva koko basusa izixhobo kwikholamu elandelayo.
"Ukudiliza kweRhine kwanika isikhongozeli sakudala esakha sasetyenziswa saza sanqunyulwa zizihlangu ezinamacala amathathu ezazikhutshelwe," utshilo uAustin. "Sebenzisa umphetho kwisithukuthezi sakho ukususa ikhava yokukhusela, emva koko uye kwikholamu elandelayo. Intshukumo nganye ithatha malunga neyure, kubandakanya ukuhambisa ikhava yokukhusela, irobhothi, ukuseka ilori ye-vacuum, ukuthintela iplastiki echithekileyo, kunye nee-hoses ezihamba. "
Ukuhlaziywa kwebala lemidlalo kuzisa abantu abaninzi abanomdla. Nangona kunjalo, indawo yokudiliza ye-hydralic yeprojekthi ayitsali nje kuphela abadlula, kodwa batsalela ingqalelo abanye abasebenzi abakwindawo.
Esona sizathu sokukhetha i-hydraulic blating yi-1 1/2 i-intshi. Imivalo yentsimbi ifakwe kwimiqolo emininzi. Le ndlela ivumela iinkonzo ze-refu ukuba icoceke ngokupheleleyo imitya yentsimbi ngaphandle kokubangela imicros ezincinci kwikhonkrithi. UAustin wathi u-Austin wathi: "Uninzi lwabantu lwaluchukumiseka - ngakumbi ngosuku lokuqala," utshilo uAustin. "Sasinenjineli yeshumi elinambini kunye nabahloli beyokubona okwenzekileyo. Bazothuswa bonke bunokwazi [i-AquaJet] Ukukwazi ukususa imivalo yentsimbi kunye nobunzulu bokungena kwamanzi kwikhonkrithi. Ngokubanzi, wonke umntu wachukumiseka, kwaye kunjalo. . Lo ngumsebenzi ogqibeleleyo. "
Ukudilizwa kwe-hydralic kuphela yinkalo enye yeProjekthi yandisa ukufundwa. Isithembiso semozulu i-Arena sihlala siyindawo yokuyila, iindlela ezinobuchule kunye nezisebenzayo nezixhobo. Emva kokususa inkxaso yenkxaso yoqobo, abasebenzi baphinda baphinde bopha eluphahleni kwiikholamu zenkxaso esisigxina. Basebenzisa iifreyimu zensimbi kunye nekhonkrithi ukwenza indawo yokuhlala yangaphakathi, kwaye uqhubeke ukongeza iinkcukacha ezicebisa.
NgoJanuwari 29, 2021, emva kokupeyinta kunye nokusayinwa ngabasebenzi okwakha, isithembiso semozulu ye-Arna kunye namalungu e-Beaken krakens, umlenze wentsimbi wokugqibela waphakama endaweni yomsitho wokuphefumla.
