The utility model discloses a water and soil conservation device for a dam, which comprises a water-retaining layer, a filter layer, a substrate layer and a flexible protective net layer. The water-retaining layer is formed by laying a high water-absorbing resin, a filter layer is formed by laying a mesh bag with gravel, a water catchment pipe is arranged at the bottom of the filter layer, and a water catchment pipe is connected with a water storage tank, and a water catchment pipe is located at the catchment pipe. A plurality of water inlet holes are arranged at the upper end of the pipe wall of the filter layer; the substrate layer is formed by laying crop straw, the flexible protective net layer is covered on the substrate layer, and the flexible protective net layer is provided with ground nails, which pass through the mesh, the matrix layer, the filter layer and the water-retaining layer of the flexible protective net layer, and are fixed with the dam. The utility model is provided with a water-retaining layer, a filter layer and a substrate layer to jointly play the role of resisting rain erosion, while the substrate layer provides nutrients for plant growth, the water-retaining layer and a filter layer provide water for plant growth, and the growing plants also play the role of water and soil conservation. The utility model has the advantages of simple construction, low cost, strong soil and water conservation capacity, and can be widely applied.
【技术实现步骤摘要】
一种堤坝水土保持装置
本技术属于水土保持
,具体涉及一种堤坝水土保持装置。
技术介绍
我国是水土流失形势比较严峻的国家之一,由于人们对土地的利用,特别是对水土资源不合理的开发和经营,使土壤的覆盖物遭受破坏;在水力侵蚀下,土壤出现表土流失、心土流失和母质流失,最终岩石暴露,使原有的生态环境遭到严重的破坏。目前防止水土流失最常用的装置为土工格栅,土工格栅的作用是通过固定部分松动的土壤,减少地表水冲刷,从而达到治理水土流失的目的;但是在大雨、暴雨天气时,土壤受到较大的水力冲蚀,由于水量较大,当雨水完全漫过土工格栅时,土工格栅则完全不起作用,雨水会对土壤进行冲蚀,导致土壤漫出土工格栅,依然存在土壤大量流失的问题。
技术实现思路
本技术的目的是提供一种堤坝水土保持装置,解决了现有技术中在受到较大的水力冲蚀时,大量的水完全漫过土工格栅,土工格栅完全不起作用,依然存在土壤大量流失的问题。本技术提供了一种堤坝水土保持装置,包括由下到上依次设置的保水层、过滤层、基质层以及柔性防护网层,所述保水层由高吸水性树脂铺设而成,所述过滤层由装有砾石的网袋铺设而成,所述过滤层的底端设有集水管,所 ...
