Abstract

The invention discloses an undisturbed sediment and overlying water synchronous acquisition and simulation method. The method includes the following steps that a sediment column is collected at the same position by means of a plurality of organic glass tubes, wherein the bottoms of the organic glass tubes are plugged with rubber plugs, and the sediment column comprises sediment and overlaying water located above the sediment; the overlaying water is extracted from the upper portions of the organic glass tubes by means of a syringe and a rubber tube and is stored in a unified mode; the tops ofthe organic glass tubes are covered with covers so that the tops of the organic glass tubes are plugged; after the rubber plugs are removed, the organic glass tubes are placed into a tank body of an annular water tank; after the covers are removed, the organic glass tubes are lifted upwards synchronously, so that the sediment is discharged from the bottoms of the organic glass tubes gradually under the action of gravity, and is laid in the tank body; the overlaying water which is stored in a unified mode is transferred into the tank body. The sediment and the overlaying water can be collectedat the same time, and meanwhile, the characteristics of the sediment cannot be damaged, so that the water environment state in the river flowing state can be accurately stimulated through the annularwater tank.

Description

technical field [0001] The invention relates to the technical field of sediment and overlying water collection and simulation technology, in particular to a method for synchronously collecting and simulating undisturbed sediment and overlying water. Background technique [0002] The annular water tank is an ideal equipment for simulating the movement characteristics of fine particles and sediment and the law of pollutant transport and transformation. It is mainly composed of an annular groove, a shear ring and a transmission device. Flow effects can simulate infinite uniform flow. At present, its application is mainly concentrated in the related research fields of the characteristics of sediment movement, and the related characteristics of the sediment-carrying water flow movement in the annular tank and the flow velocity distribution in the tank are studied, but there are relatively few studies on the use of annular tanks to explore the laws of pollutant transport and trans...
