摘要: 为了加强南水北调中线一期工程总干渠未实施防渗墙、土工膜加厚等加强措施的高填方渠段止水功能,需在渠坡和渠底衬砌板混凝土结构缝处涂抹聚脲材料进行止水。所用聚脲材料不仅要与混凝土粘接良好,还应能够适应结构缝伸缩应变。试验选取长江科学院长江工程技术公司研所发的CW680新型慢反应聚脲裂缝修补材料系统,在淅川六标段渠坡的结构缝(通缝)处进行试验,经过3个月的现场应用与试验,效果良好,能够满足该渠段输水的安全运行。

Abstract: In middle route and first stage of South-to-North water diversion project, several high fill sections of main channel were not implemented reinforcing measures such as anti-seepage wall and geomembrane thickening. For the purpose of strengthening waterproof function of these segments, a new polyurea material was used on the structural joint surface of canal slope and bottom. The polyurea material should have good adaptability of temperature deformation for structural joint and good bonding properties for concrete, so the crack repair material system CW680 of novel slow reacting polyurea developed by Changjiang River Engineering Technology Company was applied to repair structural joint of the sixth segment of the canal at Xichuan county in Henan province. Through experiment for 3 months, the waterproof ability of the novel material is testified to be good, and safety operation of the canal can be guaranteed by using the repair material.

Key words: South-to-North water diversion project, high fill canal, structural joint, polyurea, rapair material slow reaction
