Support pile, dike dam and construction method of dike dam
The invention provides a support pile, a dike dam and a construction method of the dike dam. A groove which is not smaller than the soil retaining height is formed in one end of a pile body on the soil retaining side of the support pile, and the other end of the pile body on the soil retaining side is a plain end; a groove in the cross section of one end of the pile body is in the shape of a broken line, the broken-line-shaped groove comprises a groove edge and a transition edge, and the groove edge is connected with the bottom edge of the pile body through the transition edge, so that a filling cavity can be formed in the soil retaining side of the support pile, and the filling cavity can be filled with inverted filter materials conveniently. The filling cavity is formed in the soil retaining side of the support pile, the filling cavity is conveniently filled with the inverted filter material, the flexible inverted filter layer formed by the inverted filter material can be naturally attached to a pile body joint under the pressure of a rear soil body, the self-adaptive effect is achieved, and soil particle loss is effectively prevented. And the adaptability of the flexible inverted filter structure to pile sinking deviation is high.
本发明提供了一种支护桩和护堤及其施工方法，在所述支护桩挡土侧的桩身一端上设有不小于挡土高度的凹槽，挡土侧的所述桩身的另一端为平口；所述桩身一端横截面的凹槽为折线形，所述折线形凹槽包括凹槽边和过渡边，所述凹槽边与所述桩身的底边通过过渡边连接，这样可以在支护桩挡土侧形成填充空腔，方便在填充空腔内填充反滤材料。本发明在支护桩挡土侧形成填充空腔，方便在填充空腔内填充反滤材料，通过反滤材料构成的柔性反滤层，在后方土体压力下，可使其自然贴合桩身接缝，达到自适应的效果，有效防止土颗粒流失。而且柔性反滤结构对沉桩偏差的适应性强。
