River way anti-seepage restoring ecological recovery device

Abstract

The invention discloses a river way anti-seepage restoring ecological recovery device. The device comprises a flexible anti-seepage cushion layer laying on a riverbed fracture surface, an L-shaped stop block is arranged on the surface of the flexible anti-seepage cushion layer, the bottom of the L-shaped stop block is embedded into the flexible anti-seepage cushion layer, the two sides of the flexible anti-seepage cushion layer extend to the two sides of an embankment, and ecological stone cage embankments are arranged on the two sides of the embankment; the flexible anti-seepage cushion layercomprises bottom-layer geotechnical cloth, an anti-seepage soil body and upper-layer geotechnical cloth which are arranged from bottom to top; the L-shaped stop block comprises an L-shaped pervious concrete stop block, a fixed wood pile, pebbles and gravel as well as aquatic plants; and each ecological stone cage embankment comprises living willow wood piles, surrounding rattan, binding bamboo sheaths, soil fixation flood control stones and fixing covers. According to the device, the anti-seepage and restoring of the river way is realized, so that the problem that the original seasonal waterface and water storage of the river way are difficult is solved; and the permeability coefficient of the riverbed can be reduced through the flexible anti-seepage cushion layer, the downward seepage speed of river water is relieved, and finally the purpose of anti-seepage water storage is achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy and ecological environment, in particular to a river channel seepage-proof heavy storage ecological restoration device. Background technique [0002] In many basins and river areas, especially in the northern region, most of them are seasonal rivers. There is no water in the rivers all year round. Only in the wet season will there be rainfall. The water level of the rivers will not exceed a few days before returning to a dry state, such as Linzhou Lushui River, Beijing Yuanmingyuan Pool, etc. At the same time, these rivers also have ecological problems such as lack of anti-waterlogging functions, lack of river bank vegetation, and silt clogging. [0003] In view of such problems, according to the requirements of river course management, water storage is required to form the water surface, and the rationality and economy of the anti-seepage scheme must be fully considered, so as to achie...
