Ngesikhathi sokwakhiwa kwe-grouting ephezulu, ekupheleni kwe-grouting, ukumelana nokugeleza kwe-cement slurry kuphezulu kakhulu (ngokuvamile i-5MPa), futhi ukucindezela kokusebenza kwesistimu ye-hydraulic kuphezulu kakhulu. Inani elikhulu likawoyela we-hydraulic ligeleza libuyela ethangini likawoyela ngendlela edlulayo, i-valve ehlehlayo isendaweni engu-0. Ngalesi sikhathi, lapho uqala kabusha, injini kanye ne-oyela motor izojikeleza, kodwa i-cylinder ye-hydraulic ngeke ihambe, okuholela "ekuphahlazeka". Lona umphumela wesenzo sedivayisi yokuvikela ukuphepha kwempahla. Intambo yepulaki ephakathi nendawo yesiphetho se-valve ehlehlayo kufanele ikhishwe, umgogodla we-valve uhanjiswe ngensimbi yensimbi, bese ipulaki iqiniswe ukuze ivumele ukusebenza okuvamile. Ekwakhiweni kwangempela, kungakhathaliseki ukuthi ukuqedwa kwe-grouting noma izingozi zokuxhunywa kwamapayipi zenzeka, kuzoba "nokuphahlazeka".
Le misebenzi engenhla ayikona nje ukuchitha isikhathi namafutha, kodwa futhi ayiphazamiseki. Ngakho-ke, sizame ukushintsha intambo evinjiwe esikhundleni sevalvu yokumisa (i-valve switch) epayipini legesi eliwuketshezi. Esimeni "sokuphahlazeka", zungezisa umgogodla we-valve yokumisa ngo-90 °, bese imbobo encane ivuliwe. Faka i-8 # intambo yensimbi (noma induku yokushisela yethusi) kuvalvu ehlehlayo ukuze usethe kabusha umgogodla wevalvu, ukhiphe intambo yensimbi, futhi uvale ivalve yokumisa ukuze uqalise ukusebenza. Lokhu kwenza kube lula ukusebenza futhi kusiza ukusetshenziswa okuqondile.
Lapho ukufakwa kwe-grout kuphazamiseka ngenxa yokunqanyulwa kwe-grouting noma izingozi zokuxhunywa kwamapayipi, ukuze kuvinjelwe ukufakwa kwepompo noma ipayipi lokucindezela okuphezulu, kuyadingeka ukukhipha udaka epayipini lokucindezela okuphezulu futhi usule iphampu ye-grouting kanye nepayipi lokucindezela okuphezulu. ngamanzi ahlanzekile.
Indlela yendabuko ukukhipha isixhumi sepayipi lerabha enengcindezi ephezulu bese usithulula ngokuqondile. Ngenxa yokucindezela okukhulu kodaka lukasimende emapayipini enjoloba anengcindezi ephezulu, ukufuthwa nokushwitshwa kwamapayipi enjoloba kujwayele ezingozini zokulimala, okuphinde kudale ukungcoliswa kwesizinda futhi kuthinte ukwakhiwa kwempucuko.
Ngokusho kokuhlaziywa, sikholelwa ukuthi i-valve yokukhipha ingaxazulula kangcono le nkinga, ngakho-ke i-tee ene-valve yokuvala ifakwe endaweni yokuphuma kwe-cement slurry yepompo ye-high-pressure grouting. Lapho ipayipi lidinga ukukhishwa ngenxa yokuklinywa, vula i-valve yokuvala phezu kwe-tee ukuze unciphise ukucindezela, bese ususa ipayipi lerabha, ugweme izingozi ezihlukahlukene zokuthulula i-joint, wenze lula ukusebenza.
Uguquko olungenhla lwenziwa esakhiweni, futhi impendulo yezisebenzi yaba mihle ngemva kokuqhathanisa. Emsebenzini wesisekelo senqwaba owenziwe, ubuchwepheshe be-high-pressure grouting basetshenziswa ekuvikelweni komgodi wesisekelo, futhi izinhlobo ezimbili zamavalvu zadlala indima yazo efanele ekwakhiweni kwe-grouting. Lapho kusingathwa izingozi, kulula ukusebenza, konga isikhathi nomzamo, inendawo ecacile yokukhipha uwoyela ne-slurry, futhi inokulawula okuguquguqukayo, iqinisekisa ukuhlanzeka kwendawo. Lokhu kuhluke kakhulu endaweni yamanye amaqembu okwakha ukukrufuka nokuhlela i-grout ngendlela yezinga lokuqala. Imishini ayizange ishintshwe kakhulu, kodwa umphumela uyabonakala, oye wanconywa umnikazi nomphathi.
