摘要
渠系建筑物防渗结构对于减少渗流,提高输水效率,增大过流能力等方面具有明显优越性,文章对目前传统渠系建筑物防渗结构的应用现状进行了阐述,新型矩型槽长度为2m,是传统U型槽尺寸的4倍;混凝土强度等级C50,抗渗系数F300的混凝土结构,并采用添加镀铜钢纤维增加防锈及抗裂;应用腻子型遇水膨胀橡胶,提高接头变形的相容性,提高抗渗性,是传统的渠道防渗结构U型槽、梯型槽升级换代产品。
The anti-seepage structure of canal system has obvious superiority in decreasing seepage,increasing diversion efficiency and enlarging flow capacity. The current states of the application of anti-seepage structure in traditional canal system are described in this paper. The length of new rectangular groove is 2 meters and 4 times of traditional U-shaped groove diameter. The structure of concrete is made of strength grade of C50 and anti-seepage coefficient of F300,adding copper plated steel fiber is adopted for anti rust and anti crack. Water swellable rubber putty is applied to increase the compatibility of joint deformation and anti-seepage capacity,and is the upgrading product instead of traditional channel impervious structure U type slot and ladder type trough.
