Rapid temporary cofferdam construction method
The invention discloses a rapid temporary cofferdam construction method. A cofferdam is formed by sequentially connecting a plurality of cofferdam piles. The method comprises the following steps that1, the size and the depth of the bottom, embedded into silt, of the cofferdam are determined according to the fracture size and depth of the cofferdam between adjacent lake parks at a construction site, and the number and the size of the cofferdam piles are determined according to the size of the cofferdam, and according to a determined construction position of the cofferdam, and a water construction surveying and setting-out method is adopted for surveying and setting-out on the cofferdam; 2, the plurality of cofferdam piles are inserted, driven and assembled one by one along a surveying andsetting-out line in the step 1, and backfill cavities are formed between every two adjacent cofferdam piles through combination; 3, the backfill cavities are internally refilled with silt; 4, water inthe lake parks is pumped out through a water pump, and silt in the lake parks is cleared; and 5, the cofferdam is removed. The construction method is simple, the construction efficiency is high, theconstruction difficulty is small, the cost investment is small, and the cofferdam piles can be recycled and reused.
本发明公开了一种快速临时围堰施工方法，围堰由多个围堰桩依次相连接，该方法包括以下步骤：1、根据施工地点的相邻淀泊之间围埝的断口尺寸以及深度，确定所述围堰的尺寸和底部嵌入淤泥的深度；并根据所述围堰的尺寸，确定所述围堰桩的数量和尺寸；根据所确定的围堰的施工位置，采用水上施工测量放线方法，对围堰进行测量放样；2、沿着步骤1中测量放样出的放样线，对多个围堰桩进行逐个插打及拼装，相邻围堰桩之间组合形成回填腔；3、在所述回填腔内回填淤泥；4、采用水泵将淀泊内的水抽出，并清理淀泊内的淤泥；5、围堰拆除。本发明施工方法简单，施工效率高，施工难度小，成本投入较小，围堰桩可回收重复利用。
