Uhlobo olusha lwepayipi lensimbi eliguquguqukayo elinomfutho ophezulu we-high-pressure lithuthukiswe ngempumelelo futhi lafakwa emakethe.Ukusebenza kungcono kakhulu kunensimbi yendabuko kanye nengilazi, amandla okufaka isicelo.

Ipayipi elisha likawoyela elinengcindezi ephezulu byipayipi lensimbi engenamthungoenenhlanganisela eguquguqukayo enesisindo esilula, eguquguqukayo, ukucindezela okuphezulu, ukumelana nokugqwala, ukulwa nokungcola, ukumelana noketshezi, ukusebenza kokushisa, ukulethwa kwengcindezi ephezulu, impilo ende nezinye izinzuzo.Amandla okuphuka kwe-tensile angu-51.2 MPa, amandla aguquguqukayo angu-30.5 MPa, ngokulandelana, uma kuqhathaniswa nemikhiqizo efanayo akhuphuke ngo-8% no-16% noma ngaphezulu.Lapho ukhonkolo slab imodi longitudinal lapho igebe nge grout livela ukuqhubeka grouting imizuzwana 5 kuya 10 kufanele iyekwe, kukhona amanzi phansi ipuleti, amanzi azovela kusukela imifantu ngaphansi kwengcindezi slurry, bese kudingeka uqhubeke grouting kuze kube. i-slurry ikhishwe imizuzwana emi-5 kuya kweyi-10 ngemuva kwe-(kulokhu ingcindezi ingu-2 ~ 3MPa).Ukuze i-slab kanye nonqenqema kuthathe udaka, ukucindezela akukwazi ukufinyelela inani elidingekayo, bese uvumela i-grout eduze kwe-slurry ephumayo yamahhala iqiniswe, bese iphinda ibhoboza i-grouting, ukucindezela kube ukufeza le mfuneko engenhla.I-slurry evela esikhaleni sepuleti esiseduze noma izikhala zivela lapho ihlombe eliqinile, yeka ukugcwalisa.Udinga ukugcwalisa amabhulokhi kakhonkolo lapho amabhulokhi ekhuphuka ngaphezu kwepuleti elingaphezulu elijwayelekile elingu-1 ~ 2mm, yeka ukugxumeka, ukucindezela kwe-grouting ngalesi sikhathi njengokuhoxiswa kwepuleti ngenxa yokucwiliswa kwamandla adonsela phansi 1 ~ 2mm, vele usule ngepuleti elijwayelekile ( lokhu uma ingcindezi ngokuvamile i-2-4Mpa).Lapho i-press gauge pointer ishaya ngokungavamile noma ukwanda okungazelelwe kwejeneretha yomsindo kufanele kumise ngokushesha ukugcwalisa.Uma kutholakala lapho udaka grouting imbobo kusukela ingcindezi noma ingcindezi esetshenziswa ngokusebenzisa kukakhokho ukuchichima imbobo sicindezelwe imizuzu engu-10, khipha ukhokho nge, le mbobo asikho isidingo grouting.I-Grouting kufanele inake ukuthi ingami phambi kwepayipi elinomfutho ophezulu ukuvimbela ukulimala kwesifutho (amanzi);imishini yokulungisa njalo, elungele ukuswakama, amanzi, umsebenzi kagesi ongavuzi, ukugwema izingozi zokuphepha.
