The application discloses a georaft cushion for river and lake reservoir revetment, which comprises a cage-shaped grid filled with block stone, a planting structure is arranged at intervals within the grid, a filter cushion is installed at the lower part of the grid, and a vegetation cushion is installed at the upper part of the grid. The grid is laid on the Bank of the river and lake reservoir, which can effectively slow down soil erosion and prevent waves; the upper part of the grid is equipped with a vegetation mat, which can plant plants, and can absorb nutrients and purify water through the contact of the filter mat and water; the grid is filled with lumpy stones and planting knots. This kind of good porous structure can be used for planting and cutting of many kinds of plants, which is conducive to the growth and extension of plant roots, and can quickly realize the ecological effect of river and lake revetment. The georaft cushion can be manufactured in a factory and then hoisted for construction. Compared with the traditional hard hydraulic structure, the construction is fast and the cost is low. The earthwork raft used in this application is especially suitable for waterfront soil revetment.

用于河湖库驳岸的土工筏垫以及河湖库驳岸的防护方法
本专利技术涉及驳岸的生态防护领域,具体涉及用于河湖库驳岸的土工筏垫以及河湖库驳岸的防护方法。
技术介绍
现有河湖库驳岸的加固结构多以硬质水工结构为主(如:块石浆砌、格宾石笼、混凝土、钢板桩、植被混凝土等),这种刚性结构,体积大、重量大,加重了河湖驳岸结构压力,而且生态景观效果差,工程造价高,施工周期长。
技术实现思路
本专利技术针对上述问题,克服至少一个不足,提出了用于河湖库驳岸的土工筏垫以及河湖库驳岸的防护方法。本专利技术采取的技术方案如下:一种用于河湖库驳岸的土工筏垫,包括笼状的格栅网,所述格栅网内填装有块状石料,所述格栅网内间隔安装有种植结构,所述格栅网的下部安装有过滤垫,所述格栅网的上部安装有植被垫。格栅网铺设在河湖库驳岸上,且格栅网的下部安装有过滤垫,能够实现与驳岸很好的接触,有效减缓水土流失,而且能够消波防浪,减小波浪对驳岸的冲刷侵蚀,保护驳岸;格栅网的上部安装有植被垫,植被垫上可以种植植物,通过过滤垫和水接触,能够吸附营养物质、过滤净化水质;格栅网中填装块状石料和种植结构,这种良好的多孔性结构,可以进行多种植物的栽植、扦插,有利于植物根系的生长延伸,快速实现河湖驳岸的生态效果,进一步加强对驳岸的防护效果,实现驳岸加固与生态恢复的有机统一。本申请土工筏垫可以工厂化生产,然后吊装施工,相对于传统硬质水工结构而言,施工快,造价低。本申请的土工筏垫特别适用于滨水土质驳岸。于本专利技术其中一实施例中,所述过滤垫为椰毯。于本专利技术其中一实施例中,所述格栅网为PP土工格栅网或钢丝镀锌覆塑网。优选的,格栅网为P ...
