钢筋混凝土 U型渡槽吊装后的接缝处理 ,过去多采用麻绳嵌缝 ,玻璃丝布、油膏作“两布三涂”成型。接缝处夏天易膨胀 ,冬季易收缩开裂 ,在输水期经常因气温高和水流冲刷 ,使表层脱落产生大量漏水 ,既危及工程安全又浪费水资源。为防止漏水又不影响原构件安全 ,升钟水库左分干渠? Reinforced U-shaped aqueduct after the lifting of the seams, in the past to use hemp caulking, glass cloth, ointment for the “two cloth three Tu” molding. The seams are easy to swell in summer and easy to shrink and crack in winter. During the water-transferring period, frequent leakage due to high temperature and water flow causes a lot of water leakage, which not only endangers engineering safety but also wasting water resources. In order to prevent leakage without affecting the safety of the original component, ascent of the reservoir left main trunk?
