Method for constructing seepage-proofing ecological channel of farmland
The invention relates to a method for constructing a seepage-proofing ecological channel of a farmland. The method comprises the following construction steps that 1) the longitudinal route of the channel is designed according to the original topographic conditions of the farmland, manual or mechanical excavation is carried out to reach the design size of the cross section of the channel, and excavated channel bottom and slopes on the two sides are subjected to leveling and punning work; 2) gridding cloth, a waterproof film, a diablement fort layer and plastic grids are sequentially laid in thechannel obtained after leveling and punning work is carried out, the edges of the two sides of the gridding cloth, the waterproof film, the diablement fort layer and the plastic grids extend to the slope tops of the slopes of the two sides of the channel correspondingly, and excavated earthwork is used for covering and compacting; and 3) after the gridding cloth, the waterproof film, the diablement fort layer and the plastic grids are laid in the channel, transitional inclined plates are arranged in the longitudinal direction of the channel at equal intervals, and every two adjacent transitional inclined plates are arranged in a crossing manner. According to the method, the channel has a seepage-proofing function, and meanwhile the ecological system integrity in the channel and of a wholefarmland area is maintained.
本发明涉及一种农田防渗型生态渠道的构建方法，包括有以下构建步骤：1）根据农田的原有地形条件设计渠道的纵向走向路线，采用人工或机械方式开挖至渠道横截面的设计尺寸，并对开挖后的渠底及两侧边坡进行平整和夯实作业；2）在完成平整和夯实作业后的渠道内依次铺设网格布、防水膜、棉麻布层、塑料网格，网格布、防水膜、棉麻布层、塑料网格的两侧边缘分别延伸至渠道两侧边坡的坡顶，并用开挖的土方进行覆盖压实；3）渠道内铺设完成网格布、防水膜、棉麻布层、塑料网格后，沿渠道纵向方向上等间距布置过渡斜板，相邻的两个过渡斜板之间为交叉排布。本发明的渠道具有防渗作用，同时维持渠道内和整个农田区域的生态系统完整性。
