Large lake sludge stacking and filling method
A method for high filling of sludge piles in a large lake comprises the following steps that firstly, a drainage ditch is excavated, and water is drained in the lake; 2, a drainage ditch is excavated in the sludge stacking area; 3, naturally dehydrating and airing the sludge substrate; 4, filling a first layer of earthwork grids; fifthly, the first layer of earthwork grids are backfilled with sludge; 6, naturally airing the sludge in the earthwork grids of the first layer; 7, filling a second layer of earthwork grids; 8, the second layer of earthwork grids are backfilled with sludge; 9, naturally airing the sludge in the second layer of earthwork grids; 10, slope finishing and shaping, and greening and landscaping; according to the method, drainage ditches and water collecting pits are excavated in situ for drainage, sludge is naturally dewatered and aired, a grid cofferdam is filled on an original lake sludge surface, a transport vehicle is supported to enter and exit, an excavator is constructed in situ, and sludge is backfilled in the grid cofferdam in a partitioned, partitioned and layered mode to the designed elevation, so that the problems that according to a traditional sludge filling method, the sludge solidification cost is high, a large amount of tampered land is needed, and the construction efficiency is high are solved. The problems of ecological damage, serious pollution, long construction period and high difficulty in later ecological restoration are solved.
一种大型湖泊淤泥堆高填筑的方法，包含如下步骤：一、开挖排水沟，湖内排水；二、在淤泥堆高区域，开挖排水沟；三、淤泥基底自然脱水晾晒；四、填筑第一层土方格；五、第一层土方格内淤泥回填；六、第一层土方格内的淤泥自然晾晒；七、填筑第二层土方格；八、第二层土方格内淤泥回填；九、第二层土方格内的淤泥自然晾晒；十、修坡整形、绿化造景；本发明采用原地开挖排水沟和集水坑排水，自然脱水晾干淤泥，在原湖淤泥面填筑方格围堰，支撑运输车辆进出和挖机原位施工，再在方格围堰内分区、分块、分层回填淤泥至设计标高，解决了传统淤泥填筑方法，淤泥固化成本高，征拆土地多，生态破坏、污染严重，施工周期长，后期生态恢复难度高的问题。
