Embodiment 1

[0023] In the dredged mud stockpile, the following steps are used to achieve rapid deposition and reduce the water content of the dredged mud to achieve the optimal control of the effective volume of the stockpile.

[0024] The specific steps and contents of the construction are as follows:

[0025] (1) Arrange the space drainage system in the weir before mud discharge, such as figure 1 Shown:

[0026] First, the water filter drain pipe 2 is laid step by step in the bottom horizontal direction in the cofferdam 1 and the drain pipe 3-1 is laid in the vertical direction at the bottom thereof, and the water filter drain pipe 2 and the drain pipe 3-1 are connected to each other. connected, and a drainage pipe 3-2 is arranged at the bottom of the cofferdam. The drainage pipe 3-2 communicates with the drainage pipe 3-1 and extends through the bottom of the cofferdam to the outside of the cofferdam, and the outlet of the drainage pipe 3-2 is lower than Elevation of the bottom in th...

Abstract

The invention discloses a storage yard effective volume optimum control method based on dredged sediment original state control. The storage yard effective volume optimum control method based on dredged sediment original state control is used for quickly lowering the water content in the dredged sediment and realizing the optimum control over the effective volume of a storage yard, wherein the dredged sediment is generated during the construction of hydraulic engineering, ports and piers, and navigation projects, and is low in concentration and high in clay content. By having control over theinitial water content of slurry, the deposition rate and the deposition stable concentration of slurry reach the optimal values, high-speed mud and water separation of the storage yard dredged sediment with high water content is realized, and the surplus water formed during dredging deposition is drained by making use of the dead-weight draining effect generated by the interior and exterior waterhead of the storage yard. According to the storage yard effective volume optimum control method based on dredged sediment original state control, the effects of greatly reducing the occupied area and shortening the occupation time of the storage yard are achieved by fully making use of the optimum control of the self original state of the dredged sediment over the deposition rate and the concentration after deposition is completed. The technology is simple, the cost is low, and the method is applicable to engineering practice.

Description

technical field [0001] The invention belongs to the technical field of ports, waterways and water conservancy projects, and is an optimal control for dredging mud produced in the construction of water conservancy, port wharves and waterway projects to promote the rapid separation of mud and water by controlling the initial state to achieve the effective volume of the storage yard. Large-area comprehensive disposal project of low-concentration dredged mud. Background technique [0002] In order to improve the water quality of rivers and lakes, ensure the normal flood discharge capacity of rivers and the smooth flow of inland waterways, my country has to carry out large-scale dredging and dredging projects every year. It is inevitable to produce a large amount of dredging mud. According to incomplete statistics, various types of dredging mud discarded in my country reach hundreds of millions of cubic meters every year, and the engineering volume of dredging mud treatment is hu...
