Kugwiritsa Ntchito Taike Valve Stop Valve mu High Pressure Grouting Accident Treatment

Pakumanga kwamphamvu kwa grouting, kumapeto kwa grouting, kuthamanga kwa simenti slurry kumakhala kwakukulu kwambiri (kawirikawiri 5MPa), ndipo kupanikizika kwa ma hydraulic system ndikwambiri. Mafuta ochulukirapo a hydraulic amabwerera ku thanki yamafuta kudzera podutsa, valavu yobwerera ili pa 0. Panthawiyi, poyambitsanso, injini yamoto ndi mafuta idzazungulira, koma silinda ya hydraulic sidzasuntha, zomwe zimabweretsa "ngozi". Izi ndi zotsatira za zochita za chipangizo chitetezo chitetezo zida. Waya wa pulagi womwe uli pakatikati pa chivundikiro chakumapeto kwa valve yobwerera uyenera kuchotsedwa, phata la valve lisunthidwe ndi chitsulo chachitsulo, ndiyeno waya womangika kuti alole kugwira ntchito bwino. Pakumanga kwenikweni, kaya kuthetsedwa kwa grouting kapena ngozi za plugging mapaipi zimachitika, padzakhala "ngozi".

Ntchito zomwe zili pamwambazi sizongowononga nthawi ndi mafuta, komanso zimakhala zovuta. Chifukwa chake, tidayesa kusintha waya wotsekedwa ndi valavu yoyimitsa (kusintha kwa valve) mupaipi ya gasi yamadzimadzi. "Pakachitika ngozi", tembenuzani pakati pa valve yoyimitsa ndi 90 °, ndipo dzenje laling'ono limatsegulidwa. Ikani 8 # waya wachitsulo (kapena ndodo yowotcherera yamkuwa) mu valavu yobwerera kuti mukonzenso pakati pa valavu, kutulutsa waya wachitsulo, ndi kutseka valavu yoyimitsa kuti ayambirenso kugwira ntchito. Izi zimathandizira kuti ntchito ikhale yosavuta komanso imathandizira kugwiritsidwa ntchito mwapadera.

Pamene grouting imasokonekera chifukwa cha kutha kwa grouting kapena ngozi zapaipi plugging, pofuna kupewa kuyika mu mpope kapena payipi yothamanga kwambiri, ndikofunikira kukhetsa slurry mu hose yothamanga kwambiri ndikutsuka pampu yotulutsa ndi payipi yothamanga kwambiri. ndi madzi oyera.

Njira yachikhalidwe ndikuchotsa cholumikizira cha mphira chothamanga kwambiri ndikuchichotsa mwachindunji. Chifukwa cha kuthamanga kwa simenti slurry mu mkulu-anzanu mphira mapaipi, kupopera mbewu mankhwalawa ndi kugwedezeka kwa mipope mphira sachedwa kuvulazidwa ngozi, amenenso kuchititsa kuipitsidwa kwa malo ndi zimakhudza otukuka zomangamanga.

Malinga ndi kusanthula, timakhulupirira kuti valavu yotulutsiramo imatha kuthetsa vutoli bwino, kotero kuti tee yokhala ndi valve yotseka imayikidwa pa simenti slurry outlet ya pampu yothamanga kwambiri. Pamene chitoliro chiyenera kusamutsidwa chifukwa cha kutsamwitsidwa, tsegulani valavu yotseka pa tee kuti muchepetse kupanikizika, ndiyeno chotsani chitoliro cha rabara, kupewa zoopsa zosiyanasiyana zotsitsa mwachindunji, kuchepetsa ntchitoyo.

Kusintha kwa pamwamba kunachitika pamalo omangawo, ndipo ndemanga za ogwira ntchito zinali zabwino pambuyo poyerekezera. Mu ntchito ya maziko a milu yomwe idapangidwa, ukadaulo wopondereza kwambiri udagwiritsidwa ntchito poteteza malo otsetsereka a maziko, ndipo mitundu iwiri ya mavavu idasewera gawo lawo pakumanga kwa grouting. Pochita ngozi, zimakhala zosavuta kugwira ntchito, zimapulumutsa nthawi ndi khama, zimakhala ndi malo omveka bwino a mafuta ndi slurry drainage, ndipo zimakhala ndi mphamvu zosinthika, kuonetsetsa kuti malowa ndi aukhondo. Izi zikusiyana kwambiri ndi momwe magulu ena omanga amaboola mwachisawawa ndikukonza magalasi m'njira yapamwamba. Zidazo sizinasinthidwe kwambiri, koma zotsatira zake ndi zoonekeratu, zomwe zatamandidwa ndi mwiniwake ndi woyang'anira.
