Example Embodiment

[0022] Example 1: In a lake in an urban area of ​​a city, thick sludge was deposited on the bottom of the lake. The sludge contains a lot of pollutants, and its pollution and resuspension are important reasons for lake water pollution. The sludge has accumulated, the lake water has deteriorated, the lake volume has shrunk, and the swamping has become serious. I had to make up my mind to rectify it, but piling up sludge takes up land and pollutes the environment; transporting sludge drags water and pollutes roads; landfilling sludge consumes huge amounts of money and land, and the treatment of sludge resources is not easy. Many problems have been plagued the management of lakes.

[0023] The treatment plan of the present invention includes stack yard selection, pile construction, construction of dams, dredging and dredging, pipeline mud transportation, dehydration and solidification, planting and slope protection. It is characterized by selecting a position with a higher terrain ...

Example Embodiment

[0032] Example 2: A certain lake is the water source of a water plant in a certain city. Due to the long-term natural erosion of the upstream water, both banks of the river are constantly being eroded, soil erosion, accumulation over time, and gradually thicker and thicker mud layers are gradually deposited on the bottom of the lake. . This not only increases the river bed, reduces the lake capacity, pollutes the environment, and affects traffic, but also floods during the flood season, endangers the dikes and causes floods. In the past dredging and dredging projects, the dredged silt was piled up by the lake, and the silt by the lake was returned to the lake when it rained, always clearing and silting, silting and clearing. Treatment projects are often symptomatic rather than permanent, and the efficiency of the project is low.

[0033] The treatment plan of the present invention is basically the same as that of Example 1, and it is characterized in that the self-joining sheet ...

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...
