Lub pas dej ntawm lub pas dej tauv yog ib qho tseem ceeb ntawm phab ntsa, tab sis vim yog lub pas dej sib tsoo, lub sab sauv ntawm cov tub ntxhais phab ntsa raug txiav. Yuav kom daws tau qhov teeb meem ntawm sab sauv anti-seepage, ib tug anti-seepage inclined phab ntsa yog Ameslikas ntxiv. Raws li kev soj ntsuam kev nyab xeeb thiab kev soj ntsuam ntawm Zhoutou Reservoir dam, txhawm rau daws qhov tsis muaj zog to ntawm qhov chaw thiab lub hauv paus dej ntws los ntawm ntau qhov av nkos ntawm lub pas dej, ntsug los tiv thaiv kev ntsuas xws li bedrock curtain grouting, tiv tauj nto grouting, yaug thiab rub lub tes tsho zoo backfilling curtain, thiab high-pressure spray anti-seepage phaj phab ntsa raug saws. Sab saum toj inclined phab ntsa yog them nrog composite geomembrane rau anti-seepage, thiab txuas nrog ntsug anti-seepage phab ntsa nyob rau hauv qab, ncav ib qhov siab ntawm 358.0m (0.97m saum toj no dej nyab theem).
ua haujlwm loj
1. Kev sib koom ua ke los tiv thaiv cov dej ntws thiab cov dej ntws tawm, thaum tseem muaj cov haujlwm xws li kev sib cais thiab kev txhawb nqa.
2. High composite zog, siab tev lub zog, thiab siab puncture kuj.
3. Muaj peev xwm ua kom muaj zog, kev sib txhuam coefficient siab, thiab qis linear expansion coefficient.
4. Zoo aging kuj, dav adaptability rau ib puag ncig kub ntau, thiab ruaj khov zoo.
