Abstract

The invention provides a method for de-silting a lake and constructing a lake center island and belongs to a construction technology. The method comprises the following steps of: de-silting and dredging, transporting sludge, carrying out storage yard treatment, curing the sludge, discharging tail water and constructing the lake center island while de-silting. The method disclosed by the invention solves the problem that old problems of de-silted lake water happen again. The engineering cost is reduced, the work period is shortened and the secondary pollution is managed. The method has the characteristics of smaller occupied space, no transferring of pollutants, investment saving and good benefits. According to the method disclosed by the invention, the swampiness problem is solved, the water storage amount is increased, a land resource is increased, a wetland park is established and the pollution recycling is realized. The method is a practical and feasible good method for managing and beautifying the lake.

Description

technical field

[0001] The invention relates to a lake dredging method, and at the same time it is a method for building an island in the center of a lake. Belongs to construction technology. Background technique

[0002] With the rapid economic and social development and the continuous acceleration of urbanization, it is difficult to completely control a large amount of industrial and domestic sewage around the lake, resulting in serious sedimentation in the lake, the pollutant content in the sediment generally exceeds the standard, and the ecological environment is damaged. With the intensification of water pollution, the water quality can no longer meet the normal water supply requirements, and even sudden water quality deterioration events such as "cyanobacteria outbreaks" and "black tides" have occurred, directly threatening regional water supply and ecological security. A large amount of pollutants and garbage are deposited in the lake, accumulating over time, gradual...
