Kits na Hydromill

Kits na hydromill suna wakiltar tarin kayan aiki na musamman da aka tsara don yanke ƙasa da dutsen a hankali da kuma daidaita su a cikin aikace-aikacen tushe mai zurfi. Waɗannan tsarin suna da mahimmanci wajen gina bangon diaphragm, labulen katsewa, da sauran shinge masu ɗaukar nauyi ko shinge waɗanda dole ne su tsallake yanayi masu wahala a zurfin da yawanci ya wuce mita 50. Ta hanyar haɗa aikin yanke na'ura tare da juyin slurry na ci gaba, kits na hydromill suna ba da damar hakar tsaye daidai a cikin yanayi inda hakar rami ba tare da goyon baya ba zai haifar da rushewar bango, asarar slurry mai yawa, ko canje-canje marasa kyau daga tsarin zane. Ka'idar aiki ta kit na hydromill tana mai da hankali kan kanƙara mai juyawa da oscillating wanda aka haɗa da kayan yanke da za a iya maye gurbinsu—drag bits, disk cutters, ko wheels na yanke—wanda ke hakar a hankali bisa ga daidaitaccen layin panel. Yayin da shara ke fita, slurry na ma'adinai (yawanci bentonite ko suspensions na polymer) yana riƙe da daidaiton bango ta hanyar ƙirƙirar cake na tace a kan saman da aka bayyana yayin da yake ɗaukar kayan da aka hakar don dawo da su da sake amfani da su. Wannan hanyar goyon bayan slurry tana bambanta ayyukan hydromill daga masu yanke bangon diaphragm na inji kuma tana zama mai mahimmanci a cikin ƙasa mai granules, ƙungiyoyin ruwa, da ƙananan dutsen inda daidaiton inji kawai ba zai wadatar ba. Ana amfani da kits na hydromill a cikin fasahohin tushe mai zurfi daban-daban: bangon diaphragm na dindindin da na wucin gadi, labulen katsewa na muhalli ko zubar ruwa, tsarin bangon gungun secant, bangon haɗin ƙasa-cement, da gyaran tsarin. Dabarar da aka yi amfani da ita a cikin waɗannan aikace-aikacen tana fitowa daga tsarin juyin kai na kanƙara, saurin juyawa da za a iya daidaita (yawanci 8–30 rpm), girman oscillation (0.5–2.0 mita), da kuma ƙirƙirar slurry da za a iya keɓancewa bisa ga lithology da yanayin hydrogeological da aka fuskanta. Cikakken tarin kit na hydromill yana ƙunshe da na'urar kanƙara tare da tsarin yanke da za a iya canza su, tsarin jagorar tsaye (rails na jagora ko tsarin kelly bar don kulawar matsayi), da tsarin gudanar da slurry da aka haɗa. Wannan na ƙunshe da tankunan haɗawa, famfunan juyawa, kayan tsayawa da raba (kayan tacewa, hydrocyclones, ko centrifuges), da layukan sake amfani da su waɗanda ke dawo da halayen slurry don ci gaba da aiki. Girman kanƙara yawanci yana tsakanin 0.8 zuwa 1.5 mita don panels na yau da kullum, yana faɗaɗa zuwa 1.8–2.0 mita don aikace-aikacen da ke buƙatar shinge masu kauri ko faɗi. Kits na zamani suna samun zurfin aiki na 100+ mita, wanda aka iyakance a cikin babban matsin slurry da ingancin tsarin jagora. Zaɓin kit na hydromill mai dacewa yana buƙatar tantance wasu abubuwa masu alaƙa: zurfin hakar da aka sa ran (wanda ke shafar ƙimar slurry da sarrafa matsin), rarraba ƙasa da dutsen (ƙarfin matsin da ba a iyakance ba, rarraba girman hatsi, permeability), buƙatar juriya na bango (canjin tsaye yawanci ±75–150 mm a kowace tsayin panel), da sararin aikin da ake da shi. Bayanan binciken ƙasa daga boreholes da suka gabata da gwaje-gwajen dakin gwaje-gwaje na geotechnical suna bayar da bayani kan waɗannan shawarar, suna tabbatar da cewa ƙayyadaddun kit suna dacewa da yanayin ƙasa na ƙasa da buƙatun zane. Ka'idodin aiwatarwa na masana'antu suna cikin EN 1538 (Aiwar da ayyukan geotechnical na musamman—Bangon diaphragm), wanda ke bayyana ka'idodin inganci ciki har da tsayin panel da juriya na bango. ISO 22475 jerin ka'idodin suna magance hanyoyin binciken shafin kafin a gudanar da hydromill. DIN 4126 yana ba da ƙarin jagororin fasaha na Jamus don aiwatar da bangon slurry da ka'idodin tabbatar da inganci.
