Methods and devices for fine reconstruction of sedimentation structures of flumes

A device for fine reconstruction of a sedimentation structure of a flume, comprising:

• a combined bottom plate and a combined freezing flume, wherein
• the combined bottom plate is formed by tiling and splicing a plurality of equal-thickness and rectangular basic bottom plates, a splicing gap is located between adjacent basic bottom plates, the splicing gap is filled with elastic adhesive, and the filled splicing gap is as thick as the basic bottom plates;
• the combined freezing flume includes a plurality of local freezing flumes;
• each of the plurality of local freezing flumes includes:
• a rectangular flume body with an open bottom and a hollow interior,
• at least two channels located on a top surface of the rectangular flume body and communicating with the hollow interior, wherein any one of the at least two channels is used for a freezing medium to enter, and another of the at least two channels is used for the freezing medium to flow out, and
• three metal particles with different diameters located on the top surface of the rectangular flume body at different positions from the two channels;
• each of the basic bottom plates has a local freezing flume that matches the basic bottom plate, the local freezing flume that matches the basic bottom plate satisfies that:
• a thickness of the rectangular flume body is sw/2, a length of the rectangular flume body is LL+sw/2, and a width of the rectangular flume body is LW+sw/2, where sw represents a width of the splicing gap located between the adjacent basic bottom plates, LL represents a length of the each of the basic bottom plates, and LW represents a width of the each of the basic bottom plates.
