Kodi bulangeti lopanda madzi la bentonite lopangidwa ndi chiyani:
Ndiroleni ine choyamba ndilankhule za bentonite.Bentonite amatchedwa montmorillonite.Malingana ndi kapangidwe kake ka mankhwala, amagawidwa kukhala calcium-based ndi sodium-based.Makhalidwe a bentonite ndikuti amatupa ndi madzi.Pamene bentonite yochokera ku calcium imakula ndi madzi, imatha kufika pamtundu wake.Sodium bentonite imatha kuyamwa kasanu kulemera kwake pamene ikuphulika ndi madzi, ndipo kukula kwake kumafika nthawi zoposa 20-28.Chifukwa chowonjezera chowonjezera cha bulangeti lopanda madzi la sodium bentonite ndichokwera, tsopano chimagwiritsidwa ntchito nthawi zambiri..Sodium bentonite yotsekedwa pakati pa zigawo ziwiri za geosynthetics (pansi pake ndi geotextile yoluka, ndipo chapamwamba ndi short-filament geotextile), yomwe imagwira ntchito yoteteza ndi kulimbikitsa.Zovala za bulangeti zopangidwa ndi kukhomerera kwa singano zosalukidwa zimapangitsa GCL kukhala ndi mphamvu yakumeta ubweya.
Ubwino wa bulangeti lopanda madzi la bentonite:
1: Kuphatikizika: Pambuyo pa sodium bentonite ikuphulika m'madzi, imapanga kachipangizo kakang'ono kwambiri pansi pa mphamvu ya madzi, yomwe imakhala yofanana ndi 100 nthawi ya 30cm dongo wandiweyani, ndipo imakhala ndi mphamvu zosungira madzi.
2: Madzi: Popeza bentonite imatengedwa kuchokera ku chilengedwe ndikugwiritsidwa ntchito m'chilengedwe, sichidzakalamba kapena kuwonongeka pakapita nthawi yaitali kapena kusintha kwa chilengedwe, kotero kuti ntchito yopanda madzi imakhala yaitali.Koma sangathe kugwiritsidwa ntchito mu high-concentration electrolyte solution yothetsera madzi ndi ntchito zotsutsa-seepage.
3: Umphumphu: kuphatikizidwa kwa bulangeti lopanda madzi la bentonite ndi malo apansi.Pambuyo pa sodium bentonite ikuphulika ndi madzi, imapanga thupi losakanikirana ndi chilengedwe chapansi, limatha kusintha kuti likhale losagwirizana, ndipo limatha kukonza ming'alu pamtunda wamkati mkati mwa 2mm.
4: Chitetezo chobiriwira ndi chilengedwe: Popeza bentonite imatengedwa kuchokera ku chilengedwe, sichidzakhudza chilengedwe ndi anthu.
5: Kukhudzidwa kwa malo omanga: Osakhudzidwa ndi mphepo yamphamvu komanso nyengo yozizira.Komabe, chifukwa cha kutupa kwa bentonite pokhudzana ndi madzi, zomangamanga sizingapangidwe pamasiku amvula.
6: Kumanga kosavuta: Poyerekeza ndi zipangizo zina za geotechnical, bulangeti lopanda madzi la bentonite ndi losavuta kupanga ndipo silifuna kuwotcherera.Muyenera kuwaza ufa wa bentonite pazophatikizira ndikuzikonza ndi misomali.
Cholinga cha bulangeti lopanda madzi la bentonite:
Amagwiritsidwa ntchito mwapadera m'nyanja zopanga, ma waterscapes, malo otayirako, magalasi apansi panthaka, zomangamanga zapansi panthaka, minda yapadenga, maiwe, malo osungira mafuta, mabwalo osungiramo mankhwala ndi ma projekiti ena kuti athetse kusindikiza, kudzipatula, ndi mavuto odana ndi kutayikira, komanso kukana kwambiri chiwonongeko , zotsatira zake ndizabwino kwambiri.
