    You should go to see houses or real estate companies and see different models, big and small. Do you know how to make them? The materials used for making sand tables are generally: sand table frame, stool, fine sand, soil, ground model, road, paper (cloth) strips of rivers and rivers, sawdust to render topographic tones, pigments, chess of war, team signs and team numbers for battle operations, cards for describing the names of residential areas, highlands and rivers, and bamboo sticks (bamboo sticks). Wooden sign), rope, pin, meter, brush, spade and other tools.
    1. setting up sand table
    Firstly, the sand tray frame should be placed steadily. It's better to make the direction of the sand tray consistent with the site. Then, the sand with 3-5 cm thickness and appropriate humidity should be laid. Then, the sand tray frame should be scraped and compacted with wooden boards as the plane of the lowest contour line. Then, the corresponding grid with the topographic map should be marked and the corresponding number should be marked around the sand tray frame.
    2. accumulation landform
    (1) According to the grid, the selected lowest contour lines on the topographic map can control the basic shape of the contour lines, as well as the top, saddle, foot, tilt transformation points and rivers, etc. to draw on the sand table.
    (2) Bamboo sticks are inserted into the calculated peaks, saddles, foots, tilt points and bends of rivers. The height of the bamboo mark is the thickness of the bottom sand and the height of the point on the sand table.

    (3) In the range from the lowest to the highest line, based on the bamboo sticks and contours, the outline shapes of the top, saddle and back of the mountain are piled up as the backbone, and then the other parts are trimmed. If the sand table is large, it can be stacked and stacked, first stacking in and out of difficult places, then stacking in and out conveniently. When accumulating, the topographic map should be compared at any time to show the relief of the topography correctly, and the sand should be compacted at any time to avoid collapse and deformation. If there are larger rivers and lakes, they should be dug up when dressing the landforms. After the accumulation, the sawdust should be thoroughly checked and trimmed, and scattered layer by layer from high to low in accordance with the color of the ground.

    3. setting objects
    Land objects on sand tables, such as houses, railways, bridges, trees and independent characters, are often represented by similar models. Highways and rural roads are represented by paper with different width and color; rivers are represented by blue paper or sawdust; and forests are represented by twigs or green sawdust. The size of the ground objects should be in line with the horizontal scale, and the relationship position must be correct. To set up objects, they should be set up according to the sequence of water system, residential areas, roads, forests and independent objects. Finally, place the place names, river names, mountain names and elevation notes on the corresponding positions.
    4. setting up tactics
    Tactical situation, usually according to the scheduled combat plan or training scenario, with the system of chess, temporary production of team logo, team number and other settings. When setting up, we first set up the combat demarcation line, and then proceed according to the order of the enemy first and then from the front to the deep. If we need to show the enemy, we should set up the work facilities first, and then set up tactical conditions.
    5. trimming
    After the above-mentioned work is completed, detailed checks shall be made, and the name of the sand table shall be marked, indicating the north arrow and scale, and the coordinate network shall be pulled up with a wire rope when necessary.
    The above information is the latest industry information today. If you want to know the application of sand table model or industrial model, please click on our website: http://www.jnsymx.com!
