梅林水库位于深圳市新洲河的上游,集雨面积4.26平方公里。水库以下河道长度8.3公里,经由下梅林,莲花山西麓与岗厦,在渔农村西侧汇入深圳河。 水库是为缓解东深供水工程十二月份停机检修时用水紧缺的矛盾而修建的,同时作为城市备用水源,并承担水库下游地区的防洪任务。 水库总库容1310万立方米。挡水建筑物为碾压式均质土坝,坝高36.5米,坝顶长602.5米。坝基砂砾石复盖层用地下混凝土连续墙进行防渗,坝身用土工膜防渗,混凝土连续墙与土工膜联合组成防渗体系。输水建筑物为坝下钢筋混凝土压力埋管,内衬直径1600毫米的钢管,输水至梅林转输泵站,坝后设有1600毫米锥形阀,为水库检修放空用,溢洪道布置在右坝端,用露顶式钢弧形闸门控制,闸
Merlin Reservoir is located in the upper reaches of Xinzhou River in Shenzhen City, collecting rain area of 4.26 square kilometers. The length of the river below the reservoir is 8.3 kilometers. After passing under Meilin, Lotus Mountain in Shanxi Province and Gangxia, the Shenzhen River flows into the west of the fishing village. The reservoir was constructed to ease the contradiction between the shortage of water when the Dongshen Water Supply Project was shut down for maintenance in December and serves as a backup source of water for urban areas and undertakes flood control tasks in the lower reaches of the reservoir. The total reservoir capacity of 13.1 million cubic meters. Retaining structures are roller compacted homogeneous earth dams with a height of 36.5 meters and a height of 602.5 meters. Dam foundation sand and gravel cover with underground concrete continuous wall for seepage control, dam with geomembrane seepage, concrete continuous wall and geomembrane joint anti-seepage system. The water conveyance structure is buried under the dam with reinforced concrete pressure and is lined with a steel pipe with a diameter of 1600 mm. The steel pipe is transported to the Merlin transfer pump station. A 1600 mm conical valve is provided behind the dam to drain the reservoir for maintenance. The spillway is arranged on the right Dam end, with open-top steel arc gate control, brake
