Ngethuba lokwakhiwa kwe-grouting ephezulu, ekupheleni kwe-grouting, ukuchasana kokuhamba kwe-cement slurry kuphezulu kakhulu (ngokuqhelekileyo i-5MPa), kwaye uxinzelelo olusebenzayo lwenkqubo ye-hydraulic luphezulu kakhulu.Isixa esikhulu se-oyile ye-hydraulic ibuyela kwitanki yeoli ngokusebenzisa i-bypass, kunye nevalve ebuyisela umva kwindawo ye-0.Ngeli xesha, xa uqala kwakhona, i-motor kunye ne-oil motor iya kujikeleza, kodwa i-cylinder ye-hydraulic ayiyi kuhamba, kubangele "ukuphazamiseka".Esi sisiphumo sesenzo sesixhobo sokukhusela ukhuseleko lwesixhobo.Ucingo lweplagi olusembindini wesivalo sevalve ebuyela umva kufuneka lususwe, undoqo wevalve uhanjiswe ngentsimbi yentsimbi, emva koko ucingo lweplagi luqiniswe ukuvumela ukusebenza okuqhelekileyo.Kulwakhiwo lwangempela, nokuba ukupheliswa kwegrouting okanye iingozi zokuplaga umbhobho zenzeka, kuya kubakho "ukuphazamiseka".
Le misebenzi ingasentla ayikona nje ukuchitha ixesha kunye neoli, kodwa ibuye iphazamise.Ngoko ke, sizame ukutshintsha ucingo oluvaliweyo kunye nevalve yokumisa (i-valve switch) kumbhobho werhasi enyibilikisiweyo.Xa kwenzeka "ukuphazamiseka", jikelisa i-valve core nge-90 °, kwaye umngxuma omncinci awuvaliwe.Faka i-8 # yentsimbi yentsimbi (okanye intonga yokuwelda ubhedu) kwivalve umva ukuseta kwakhona undoqo wevalve, utsale ucingo lwentsimbi, kwaye uvale isivalo sokumisa ukuze uqalise ukusebenza kwakhona.Oku kwenza kube lula ukusebenza kwaye kuququzelele ukusetyenziswa okuthe ngqo.
Xa i-grouting iphazamiseka ngenxa yokupheliswa kwe-grouting okanye iingozi zokuvala umbhobho, ukwenzela ukuthintela ukubekwa kwimpompo okanye umbhobho woxinzelelo oluphezulu, kuyimfuneko ukukhupha i-slurry kwi-hose ephezulu yoxinzelelo kunye nokugungxula ipompo yokukhupha kunye ne-high-pressure hose. ngamanzi acocekileyo.
Indlela yendabuko kukususa isidibanisi se-rubber ye-rubber ephezulu yoxinzelelo kwaye ikhuphe ngokuthe ngqo.Ngenxa yoxinzelelo oluphezulu lodaka lwesamente kwimibhobho yerabha enoxinzelelo oluphezulu, ukutshiza kunye nokujingalwa kwemibhobho yerabha kuqhelekile kwiingozi zokwenzakala, ezibangela ungcoliseko lwesiza kwaye zichaphazele ulwakhiwo oluphucukileyo.
Ngokohlalutyo, sikholelwa ukuba i-valve yokukhupha iyakwazi ukusombulula le ngxaki, ngoko ke i-tee ene-valve yokuvala ifakwe kwi-sement slurry outlet yempompo ephezulu yoxinzelelo.Xa umbhobho kufuneka ukhutshwe ngenxa yokukrwitsha, vula ivalve yokuvala kwi-tee ukuze unciphise uxinzelelo, uze ususe umbhobho werabha, ugweme iingozi ezahlukeneyo zokukhulula ngokuthe ngqo i-joint, ukwenza lula ukusebenza.
Olu tshintsho lungasentla lwenziwa kwisiza sokwakha, yaye ingxelo yabasebenzi yaba ntle emva kokuthelekisa.Kumsebenzi wesiseko semfumba owenziweyo, itekhnoloji yoxinzelelo oluphezulu lwegrouting yasetyenziswa kwisiseko sokhuselo lwethambeka lomngxuma, kwaye iindidi ezimbini zeevalvu zadlala indima yazo efanelekileyo kulwakhiwo lwegrouting.Xa uphatha iingozi, kulula ukusebenza, ugcina ixesha kunye nomgudu, unendawo ecacileyo yeoli kunye ne-slurry drainage, kwaye inokulawula okuguquguqukayo, ukuqinisekisa ukucoceka kwendawo.Oku kwahluke kakhulu kumboniso wamanye amaqela okwakha ngokungenamkhethe nokucwangcisa igrout ngendlela yodidi lokuqala.Isixhobo asizange sitshintshwe kakhulu, kodwa umphumo uyabonakala, oye wadunyiswa ngumnini kunye nomphathi.
