竹构水塔的开放式剖面

An architectural cutaway illustration of a small bamboo water tower: pitched roof, exposed blue storage tank, cross-braced bamboo supports, ladder up to the tank and a ground-level trough beside a small vegetable garden. One coherent building, plausible construction, fine ink lines and restrained watercolor; no text labels.

绘制一幅竹构小水塔的开放式建筑剖面图：坡屋顶、露出的蓝色蓄水桶、交叉竹支撑、直达水箱的梯子和地面的水槽都清晰可见，旁边有小片菜地。保持单一建筑、可信结构、细线与淡水彩，不写文字标签。
