Cofferdam construction method
The invention discloses a cofferdam construction method, and relates to the technical field of water conservancy construction. The method comprises the following steps: determining an overwater cofferdam lake filling area, carrying out overwater temporary enclosure on the cofferdam lake filling area, installing a dense-mesh net in the area above the water surface, and installing a geomembrane net in the area below the water surface; steel sheet pile driving is started, meanwhile, rock cofferdam filling operation is conducted till the steel sheet piles are in bridge joint with the two banks of the overwater cofferdam lake filling area, and meanwhile rock cofferdam filling operation on the first side face is completed; earthwork backfilling is conducted, and the whole stone cofferdam is completed; the stone cofferdam above the lake bottom is grouted and filled with cement paste; and a traffic relief road and a construction road are laid on the top of the stone cofferdam. According to the cofferdam construction method, the overwater cofferdam lake filling area is determined, the overwater temporary enclosure is conducted on the cofferdam lake filling area, sewage generated in the cofferdam construction process is prevented from entering other areas of the lake surface, and lake water pollution is prevented.
本发明公开了一种围堰施工方法，涉及水利施工技术领域。确定水上围堰填湖区域，将所述围堰填湖区域进行水上临时围蔽，在水面以上区域安装密目网，水面以下区域安装土工膜网；开始钢板桩打桩，同时进行石方围堰填筑作业，直至钢板桩跨接所述水上围堰填湖区域的两岸，同时所述第一侧面的石方围堰填筑作业完成；进行土方回填，完成整体的石方围堰；将湖底以上的石方围堰内进行采用水泥浆进行灌浆充填；在所述石方围堰顶部铺设交通疏解道路及施工便道。本发明提供的围堰施工方法确定水上围堰填湖区域，将所述围堰填湖区域进行水上临时围蔽，避免围堰施工过程中产生的污水进入湖面其他区域，防止湖水污染。
