    The flow chart illustrates the constructing process of a storage area using concrete canvas.

    概述段

    Overall, the whole procedure consists of 8 steps, beginning with manufacturing concrete canvas and ending at utilizing this area for storage.

    思路要点：
    - 共8步
    - 第一步：组装concrete canvas
    - 最后一步：仓库建成，用于储存

    Body paragraph 1

    The process begins with the production of concrete canvas, which consists of three layers. The top layer is made from a fibrous material, with a dry concrete lying beneath it, and the bottom layer is designed for waterproofing. Afterwards, it is transported to the construction site where it will be unwrapped. The canvas is then spread out on the ground, with one end attached to a truck by a rope. As the truck slowly moves forward, the canvas is extended until it reaches a length of 10 meters. At this point, the four corners are secured to the ground with pegs.

    思路要点：
    - 1concrete canvas由三种材料制成（表层→fibrous material；中间→dry concrete；底层→waterproof）
    - 2随后，concrete canvas会被运输，3以备拆封
    - 4固定concrete canvas（一端由绳子连接在卡车上→卡车缓慢移动，concrete canvas被拉大至10米→四个角落由pegs固定）

    Body paragraph 2

    Pumping air into this canvas is the next step. Once it is inflated to a height of 8 meters, a door is installed in front of the tent. Subsequently, people will spray water onto the canvas. After 20 to 24 hours, the tent is fully set up and ready for the use as a storage area.

    思路要点：
    - 5：加入空气
    - 6：膨胀至8米高，水洗表面
    - 7：放置20-24小时
    - 8：装置完成，用于储存物品
