Film bag sand cofferdam construction method
The invention provides a film bag sand cofferdam construction method. The film bag sand cofferdam construction method comprises the following steps that a riverbed is trimmed; base layer film bag sand is laid and filled; a sublayer film bag sand set is laid and filled, wherein the sublayer film bag sand set comprises two or more layers of sublayer film bag sand, and when the sublayer film bag sand set is laid and filled, the sublayer film bag sand is laid and filled layer by layer from the base layer film bag sand to the preset water surface elevation till the sublayer film bag sand set reaches the preset water surface elevation; a top layer film bag sand set is laid and filled, wherein the top layer film bag sand set comprises at least one layer of top layer film bag sand, and when the top layer film bag sand is laid and filled, the top layer film bag sand is laid and filled layer by layer from the sublayer film bag sand set to the preset height till the top layer film bag sand set reaches the preset height; and steel sheet pile construction is conducted, wherein after the base layer film bag sand, the sublayer film bag sand set and the top layer film bag sand set are laid and filled, steel sheet piles are inserted and hit on the inner surge side in the riverbed width direction, and the base layer film bag sand and the sublayer film bag sand set abut against the steel sheet piles. According to the film bag sand cofferdam construction method, a cofferdam body can be prevented from sliding seriously, and the stability of a cofferdam can be improved.
本发明提供一种膜袋砂围堰施工方法，包括以下步骤：河床修整；铺填基层膜袋砂；铺填次层膜袋砂组：次层膜袋砂组包括两层以上的次层膜袋砂，次层膜袋砂组铺填时，自基层膜袋砂向预设水面标高逐层铺填次层膜袋砂，直至次层膜袋砂组达到预设水面标高；铺填顶层膜袋砂组：顶层膜袋砂组包括至少一层顶层膜袋砂，顶层膜袋砂铺填时，自次层膜袋砂组向预设高度逐层铺填顶层膜袋砂，直至顶层膜袋砂组达到预设高度；钢板桩施工：在基层膜袋砂、次层膜袋砂组和顶层膜袋砂组铺填完成后，在内涌侧沿河床宽度方向插打钢板桩，并使基层膜袋砂、次层膜袋砂组抵靠在钢板桩上，该膜袋砂围堰施工方法能够防止堰体发生严重滑移且可提高围堰的稳定性。
