分开铺设的护底软体排和袋装砂在工况条件复杂情况下难以确保铺设质量,施工进度受到制约,施工成本增加.通过技术革新,改变常规的排袋加工工艺及施工方法,将尺寸较短的两张软体排和一张砂袋体加工为一张通长的联体排袋,进行整体铺设及充灌,解决了常规铺设软体排及袋装砂的施工质量问题,大幅度提高了施工效率,降低了施工成本,创造了较高的经济效益.%Separate laying of the bottom protection soft mattress and sand bags in the complex working conditions is difficult to ensure the laying quality, the construction progress is restricted, and the construction cost is increased. Through technical innovation, we changed the conventional processing technology and construction method of the soft mattress and sand bags, connected two short soft mattresses and a sand bag into a long couplet platoon, which was laid and filled in the water as a whole. It has solved the laying construction quality problems of soft mattress and sand bags, and greatly improved the construction efficiency, reduced the construction cost, created a high economic efficiency.
