1998年上半年,焦作市对位于市区中心的群英河中段进行了治理,并在繁华地段修建橡胶坝,以蓄清水形成湖面,净化空气,美化环境,群英湖水面面积约2万m~2,平均水深1.5m,总容积3万m~3。由于群英河为一季节性山洪河道,平时无水,汛期洪水对河道冲刷又较严重,所以人工湖为了能蓄住水又能经得起冲刷,湖底河床采取了砼及浆砌石铺盖加复合土工膜防渗工程措施。从竣工蓄水以来,工程运行情况良好。下边将群英湖施工中采用的复合土工膜产品及其拼接,几个主要部位的铺设、连接形式及施工工艺介绍给大家(下文图中尺寸单位均
In the first half of 1998, Jiaozuo City was able to control the middle of the Qunying River, which is located in the center of the downtown area, and constructed rubber dams in prosperous areas to clean the lake, clean the air and beautify the environment. The surface area of Qunying Lake is about 20,000m 2 , The average depth of 1.5m, the total volume of 30,000 m ~ 3. Because the Qunying River is a seasonal flash flood channel, it usually has no water and the floodwaters flood the river more seriously. Therefore, in order to be able to store water and withstand the erosion, the lake bottom river adopts concrete and masonry to cover and compound Geomembrane seepage control engineering measures. Since the completion of storage, the project is in good condition. Below the construction of Qunying Lake composite geomembrane products and their splicing, the laying of several major parts of the connection form and construction technology introduced to everyone (the following figure size units are
