Idamu ledamu ekuqaleni laliwudonga oluwumgogodla, kodwa ngenxa yokuwa kwedamu, ingxenye engaphezulu yodonga oluwumgogodla yanqanyulwa. Ukuze kuxazululwe inkinga ye-anti-seepage ephezulu, udonga oluthambekele oluphikisana nokubona ikhasi lwengezwe ekuqaleni. Ngokokuhlolwa nokuhlaziywa kokuphepha kwedamu laseZhoutou Reservoir, ukuze kuxazululwe indawo evuzayo ebuthakathaka kanye nokuvuza kwesisekelo sedamu okubangelwa ukudilika kwenhlabathi okuningi kwedamu, izinyathelo eziqondile zokunqanda ukugeleza kwamanzi ezifana ne-bedrock curtain grouting, indawo yokuxhumana, ukushaywa kanye ikhethini lokubamba kahle eligcwalisa ikhethini, kanye nodonga lwepuleti lepuleti lesifutho esinomfutho ophezulu we-anti-seepage lamukelwa. Udonga oluphezulu oluthambekele lumbozwe nge-geomembrane eyinhlanganisela ye-anti-seepage, futhi luxhunywe odongeni oluqondile olumelene nokuvuleka phansi, lufinyelele ukuphakama okungu-358.0m (0.97m ngaphezu kwezinga lesheke lezikhukhula)
umsebenzi omkhulu
1. Ukuhlanganisa imisebenzi evimbela ukugeleza kwamanzi kanye ne-drainage, kuyilapho futhi inemisebenzi efana nokuhlukanisa kanye nokuqinisa.
2. Amandla aphezulu ayinhlanganisela, amandla acwebile aphezulu, nokumelana nokubhoboza okuphezulu.
3. Umthamo wokudonsa amanzi onamandla, i-coefficient ephezulu yokungqubuzana, kanye ne-coefficient yomugqa wokunweba ophansi.
4. Ukumelana nokuguga okuhle, ukuguquguquka okubanzi ebangeni lokushisa kwemvelo, kanye nekhwalithi ezinzile.
