秧田箐水库除险加固工程设计(附CAD图纸)(含选题审批表,任务书,开题报告,中期检查表,论文说明书12800字,CAD图纸7张)
摘 要:秧田箐水库位于楚雄州禄丰县秧田箐村,是一座以灌溉及防洪为主的综合性水利工程。本设计主要是对秧田箐水库坝体,溢洪道及输水涵洞进行除险加固。对大坝坝基及两岸坝肩进行帷幕灌浆;溢洪道底板砼衬砌,浆砌石侧墙拆除重建;修补输水涵洞裂缝并进行回填灌浆,使其满足设计要求。
关键词:病险水库;除险加固;帷幕灌浆;翻修衬砌
Design of Danger Elimination and Reinforcement for YangTianJing Reservoir
Abstract: Yang Tianjing reservoir is located in Yang TianJing village ,LuFeng county , ChuXiong prefecture .It is a comprehensive water conservancy project that mainly in irrigation and flood control . This design is mainly let the Yang Tianjing’s reservoir dam, spillway and water tunnel safety operation. Curtain grouting on both sides of the dam and the abutment ; With concrete lining the spillway backplane and rebuilding the PlasmaQiShi side wall ; In order to meet the design requirements, repaired the crack of water culverts and empty culverts of backfill grouting.
Key words: sickness danger reservoir; danger elimination and reinforcement; curtain grouting;
overhaul lining
工程概况
秧田箐水库位于楚雄州禄丰县勤丰镇秧田箐村,秧田箐水库流域近似呈扇形,整个流域属构造侵蚀中低山地形,其地势西南高东北低。秧田箐水库流域面积10.71km2,主河道长4.55km,主河道平均比降36.6‰。现状坝顶高程为1944.75~1945.18m ,坝轴线长82m,总库容120万m3(实测)。秧田箐水库坝址以上控制径流面积10.71 km2,现状枢纽建筑物主要由大坝、溢洪道和输水涵洞组成。大坝坝型为均质土坝,坝轴线长82m,坝顶宽5m,现状坝坡坡比分别为:大坝上游坝坡为:从1944.75m~1941.83m为1:2.4,其下到河床坝坡为1:2.8。大坝下游坝坡为:从1944.75m~1939.75m为1:1.9,从1939.75m~1930.20m为2.66,从1930.20m~1923.90为2.58,1924.50m高程处为排水体,宽1.57m,其下到河床外坡比为1:2.0。溢洪道位于大坝右岸坝肩上,开敞式有闸控制宽顶堰。溢流堰堰顶高程为1941.78m,溢洪道全长125m,输水涵洞位于大坝顺流右岸山体内,总长87m,洞身长79m,量8.50 m3/s。输水涵洞主要由启闭塔、洞身段及工作桥组成。进口底板高程1930.33m,出口底板高程1929.92m,底坡i=0.005,最大流量8.50 m3/s。输水涵洞主要由启闭塔、洞身段及工作桥组成。
