重庆市长寿区新市街道办事处:
你单位关于长寿区桃花溪流域凤城新市段水土保持治理工程(河道生态治理工程部分)洪水影响评价报告审批申请已收悉,我局组织专家对《长寿区桃花溪流域凤城新市段水土保持治理工程(河道生态治理工程部分)洪水影响评价报告》(送审稿)进行了审查。根据河道管理有关法律法规和专家评审意见,现批复如下:
一、同意长寿区桃花溪流域凤城新市段水土保持治理工程(河道生态治理工程部分)洪水影响评价报告的结论
(一)工程所在河段防洪评价标准为10年一遇。
(二)本工程涉及河流为桃花溪河左岸一级支流纳溪河河口段,本工程河道生态治理3.700km,河道疏浚3.700km,主要涉河建设内容包括新建防洪护岸全长6.997km(左岸3.381m,右岸3.616m),新建9处下河梯步,新建穿堤管涵4处,新建过河汀步7处,改造拦河堰2处。
1.护岸工程
河道堤体及护岸结构分别为格宾镇脚+休闲步道+和景观绿化带。
格宾镇脚顶为河道常年水位。格宾笼挡墙镇脚规格为长×宽×高:1×1×1m和1.5×1×1m,内部按照1m间隔布置隔板。休闲步道位于格宾镇脚顶部,宽度为2.5m,休闲步道顶高程按比河道常年水位高出0.35m进行设计。
2.下河梯步
本工程共设9处下河梯步,其中,左岸有3处,分别位于桩号KZ2+954.22、KZ0+677.21、KZ1+263.19,右岸有6道,分别位于KY3+030.73、KY2+770.28、KY2+248.25、KY2+084.31、KY0+634.79、KY0+965.14。下河梯步采用斜坡坡面梯步:梯步总宽5.0m,均采用C25钢筋砼浇筑,C25钢筋砼梯步厚度为0.15m,下设0.1m厚碎石垫层,两侧设C20砼步带,尺寸为0.4m×0.8m(宽×高)。
3.穿堤管涵
本工程共设4个穿堤管涵,分别位于桩号KZ0+376.69、KY2+051.14、KY3+025.18、KZ3+135.42,采用DN1000钢筋砼预制管,管道基础采用C20砼管形基础,基础厚0.2m,管涵底坡i=0.05。管涵进口设置集水井,出口伸出格宾镇脚至河道。
4.过河汀步
新建汀步7处,汀步置于C20砼基础上,顶部宽2.0m,上游侧直立,下游侧坡比1:1.0,基础置于基岩上,上下游开挖面均采用大块石回填。汀步顶部高程为河道常年蓄水位+0.1m,汀步为M7.5浆砌块石,单个汀步宽度0.5m,长1.5m,高0.8m,汀步间间隔0.4m。
5.拦河堰
本工程拆除重建2座拦河堰,分别位于桩号K0+092、K2+509,拦河堰采用C20砼浇筑,拦河堰顶部宽2.0m,上游侧直立,下游侧坡比1:1.0,基础置于基岩上,上下游开挖面均采用大块石回填。拦河堰顶部设置汀步,汀步为M7.5浆砌块石,单个汀步宽度0.5m,长1.5m,高0.8m,汀步间间隔0.4m。
