The disc was mainly used in war. Now we often see commanders standing in front of terrain models to study battle plans in military movies. So do you know how the sand table is made? Today I want to share with you how to make a sand table model.
1.擺好沙盤
1. Set the sand table
首先將沙盤安 全放置，盡量使沙盤的方位與當?shù)匾恢?，然后鋪?-5厘米厚、濕度適宜的沙子，用木板刮去，在沙盤周圍標出與地形圖相對應的網(wǎng)格，并記下相應的數(shù)字。
First, place the sand table safely, try to make the orientation of the sand table consistent with the local, then lay 3-5cm thick sand with appropriate humidity, scrape it off with a wooden board, mark the grid corresponding to the topographic map around the sand table, and write down the corresponding numbers.
2.堆積地貌
2. Accumulation landform
（1）根據(jù)網(wǎng)格，在地形圖上畫出選定的小等高線，可以控制地形基本形狀的等高線，如山頂、馬鞍、山腳、傾斜過渡點、河流等沙盤上的位置。
(1) According to the grid, draw the selected small contour on the topographic map, which can control the contour of the basic shape of the terrain, such as the position on the sand table such as the top of the mountain, saddle, foot of the mountain, inclined transition point, river, etc.
（2）起伏明顯的計算點，如山頂、馬鞍部分、山腳、傾斜過渡點、河灣等。都是用竹簽插的，竹簽的高度是沙盤上的點的高度加上底層沙子的厚度。
(2) Calculation points with obvious fluctuation, such as the top of the mountain, saddle part, foot of the mountain, inclined transition point, bend, etc. They are all inserted with bamboo sticks. The height of the bamboo sticks is the height of the points on the sand table plus the thickness of the bottom sand.
（3）從min到高線范圍內(nèi)，以竹簽和等高線為基礎，將山頂、馬鞍和山背的粗糙形狀堆砌成樹干，然后修剪其他部分。如果沙盤比較大，可以分塊堆放，先堆放在困難的地方，再堆放在方便的地方。堆放時，應隨時對比地形圖，正確顯示地形起伏，砂層應隨時壓實，
(3) From min to the high line range, based on bamboo sticks and contour lines, stack the rough shapes of the top of the mountain, saddle and back of the mountain into trunk, and then trim other parts. If the sand table is relatively large, it can be stacked in blocks, first in a difficult place, and then in a convenient place. During stacking, the topographic map shall be compared at any time to correctly display the topographic relief, and the sand layer shall be compacted at any time,
避免坍塌變形。如果有的話。
Avoid collapse and deformation. If so.
3.設置地面物體
3. Setting ground objects
沙盤上的地物，如房屋、鐵路、橋梁、樹木、獨立地物等，往往用相似的模型來表示，而道路、村莊則用不同寬度和顏色的紙（布條）來表示；河流以藍紙條或木屑為代表；樹是用小枝或綠木屑來代表的。特征的大小應與水平比例尺相適應，并且關系位置應正確。特
Features on the sand table, such as houses, railways, bridges, trees, independent features, etc., are often represented by similar models, while roads and villages are represented by paper (cloth strips) of different widths and colors; Rivers are represented by blue paper or sawdust; Trees are represented by twigs or green sawdust. The size of the feature shall be appropriate to the horizontal scale, and the relationship position shall be correct. special
征應按水系、居住區(qū)、道路、森林和獨立特征的順序設置。在相應的位置插入地名、河名、山名、海拔筆記等卡片。
The land requisition shall be set in the order of water system, residential area, road, forest and independent characteristics. Insert place names, river names, mountain names, altitude notes and other cards in the corresponding positions.
4.設定戰(zhàn)術態(tài)勢
4. Set tactical situation
戰(zhàn)術情況，通常根據(jù)預定的作戰(zhàn)計劃或訓練來確定，暫時通過使用標準的戰(zhàn)棋、團隊標志和團隊編號來確定。設定時，先設定戰(zhàn)斗分界線，然后按順序，從正面到縱深。如果需要給敵人看的話，在加固工程的時候，先設置好工作設施，再設置戰(zhàn)術態(tài)勢。
The tactical situation is usually determined according to the predetermined battle plan or training, and temporarily determined by using standard chess, team logo and team number. When setting, first set the battle boundary, and then in order, from front to depth. If it is necessary to show the enemy, when strengthening the project, first set up the working facilities, and then set up the tactical situation.
