为使该边坡防护板整体稳定不至于在安装后发生倾覆并且使其自重相对较小便于施工，设计防护板本体1-1的厚度l₁为5cm，防护壁1-2的厚度l₂为3cm。同理将榫头1-3的尺寸设计成半径r₃为1.5cm，高h₂为3cm，而卯眼1-4的半径r₄设计成1.6cm，便于榫头1-3与卯眼1-4的对接且能保证其相对的稳定性。排水孔1-5的半径r₂设计为2cm则是出于对排水效果的考虑，太小不便于排水，太大又会导致土体大量漏出，不利于稳定。为了进一步对其进行加固，防止因外力作用而倒塌，在防护板本体1-1的左侧设计一半径r₅为1cm的铆钉孔1-6，所述铆钉孔1-6的孔心距离防护板本体1-1底部为防护板本体1-1宽度的2/3，安装完毕后再将铆钉沿铆钉孔1-6打入并固定，能有效防止边坡的浅层滑动。由此导出生态复合型防护板的重量计算公式：To sum up, in view of the consideration of construction difficulty, construction cost, overall strength and aesthetics, the overall length and width of the ecological composite slope protection board are controlled at about 1 meter, and the protection wall 1-2 and the protection A distance of 10cm is reserved at the joints of the plate body 1-1, so for a certain fixed slope ratio, the height of the protective wall 1-2 is firstly determined by the slope ratio and the overall size of the ecological composite slope protection board. h ₁ and radius r ₁ , so that height h ₁ : r ₁ = slope ratio, the size of the slope protection plate in the above-mentioned embodiment 1 to embodiment 5 is determined according to this method, and this size design can ensure that when When the protective plate was installed on the slope corresponding to the slope ratio, its protective wall 1-2 was upright, so as to maintain an attractive appearance and form a certain space to facilitate planting plants on the basis of overall stability.
