池塘护坡的三种简易做法

池塘护坡的三种简易做法,用砖瓦厂废弃的坏砖,不合格的瓦片作为护坡材料,用蛇皮袋,泥土作为护坡材料,用聚氯乙烯网布作为护坡材料.
一、用砖瓦厂废弃的坏砖、不合格的瓦片作为护坡材料
首先,挖掉池底淤泥,在埂土上用瓦片逐行有序地排列。在每行之间要有一定的坡度,并逐层填土。在排列到1米高后再用废弃的坏砖将瓦片到坡顶之间填实压紧即可。这种方法成本稍高,但扩坡的效果佳,每年在小水时将扩坡处再修补,可确保多年的护坡效果,且原材料可重复利用。
二、用蛇皮袋、泥土作为护坡材料
这种方法同样要挖掉淤泥,将装有泥土的蛇皮袋平放在埂土上,加到2~3层后在外围填土,在逐层相加过程中要有一定的坡度,以防蛇皮袋下滑。为达到更好的防滑效果,可在装土的袋子外用木桩打进土里,木桩伸到蛇皮袋外的高度不宜过高。这种方法方便实用,成本低,效果好,经久耐用。
三、用聚氯乙烯网布作为护坡材料
在扩坡前要将坡面上的杂草清除干净,使坡面平整。在网布护坡之前要缝一个可装进卵石的网袋,装上卵石后再缝合在护坡的网布下方,将卵石埋入坡底的泥土中。上部网片用绳固定后用土将上缘埋入土中,以防滑落,同时确保网片与坡面紧贴以便有较好的护坡效果。
