Abstract

The utility model discloses a system is reformed transform to reservoir deposits crystallizing field river system, include section ground sills that sets up to go into reservoir mouth upper reaches predetermined distance in the river and locate, the waterwall height that section ground sills was placed in below the riverbed is established to 25~30m, and the upstream face and the back side that cut the ground sills are cascaded domaticly, sloping than establishing to 1: 2.5, the domatic of upstream face has two sections, and the riverbed plane is connected to the one of which section, and dam crest is connected to another section, connect through the platform face between domatic for these two sections, the domatic of back side is one section, many irrigation canals and ditches have been seted up on the mud flat of crystallizing field, irrigation canals and ditches kuan du > 1m, irrigation canals and ditches shen du > the water head in river wet season and dry season, will by irrigation canals and ditches a plurality of ecological islands are separated into to the crystallizing field, and it has arbor, bush or herbaceous plant to plant respectively on ecological island. Be decomposed into a plurality of ecological islands with the large tracts of land mud flat to implement the topography structure to every ecological island, promote its biodiversity level, in order to reach the effect of fixing the sand.

Description

A kind of reservoir deposits crystallizing field waterline classifying system
Technical field
The utility model belongs to reservoir reconstruction technical field, especially reservoir deposits crystallizing field waterline classifying system.
Background technology
The northern reservoir first half carries influence to sediment by river, and long term accumulation very easily forms large-area beach, and silt, rubble are easily piled up, and if things go on like this reservoir capacity will reduce, and affects the effect of its flood retention retaining and adjustment current.
Utility model content
Based on this, be vulnerable to silting cause beach to affect the technical problem of reservoir function for solving reservoir in above-mentioned prior art, the utility model provides a kind ofly to be intercepted silt in river and the beach of formation is resolved into the reservoir deposits crystallizing field waterline classifying system of Eco-Island.
For realizing above-mentioned utility model object, the utility model takes following technical scheme: a kind of reservoir deposits crystallizing field waterline classifying system, comprise and be arranged on section ground sills that river enters preset distance place, reservoir mouth upstream, the dam crest of described section of ground sills is wide is 0.5m, cut ground sills dam body and go deep into both sides, river course basement rock 2m, cut the waterwall height that ground sills is placed in below riverbed and be set to 25 ~ 30m, cutting the upstream face of ground sills and back side, to be staged domatic, slope ratio is set to 1:2.5, the domatic of described upstream face has two sections, one section connects riverbed plane, another section connects dam crest, these two sections domatic between connected by flat upper surface, the domatic of described back side is one section, the beach of crystallizing field offers many irrigation canals and ditches, irrigation canals and ditches width G reatT.GreaT.GT1m, the water-head in trench depth > river wet season and dry season, by irrigation canals and ditches, described crystallizing field is separated into multiple Eco-Island, Eco-Island is planted respectively and is implanted with arbor, shrub or herbaceous plant.
Compared with prior art, the utility model has following beneficial effect: by adopting ground sills technology before river warehouse-in, intercept the silt that river carries; Enter Sediment Siltation place, pool at reservoir, in topography reform mode, large area beach is decomposed into multiple Eco-Island, and terrain configuration is implemented to each Eco-Island, promote its bio-diversity level, to reach the effect of fixing the sand.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 section of ground sills generalized section;
Fig. 2 is the utility model embodiment 1 reservoir deposits crystallizing field waterline classifying entire system top view;
Reference numeral: 1, cut ground sills; 2, dam crest; 3, flat upper surface; 4, irrigation canals and ditches; 5, Eco-Island; 6, waterwall.
Detailed description of the invention
The utility model is described in detail below by way of the drawings and specific embodiments.
Embodiment
Refer to shown in Fig. 1 to Fig. 2, a kind of reservoir deposits crystallizing field waterline classifying system, comprise and be arranged on section ground sills 1 that river enters preset distance place, reservoir mouth upstream, dam body materials is reinforced concrete structure, preset distance in the present embodiment is set to about 300 meters, cutting the dam crest 2 of ground sills 1 wide is 0.5m, for guaranteeing to cut husky effect, cut the waterwall 6 that ground sills 1 is placed in below riverbed and be highly set to 25 ~ 30m, cutting the upstream face of ground sills 1 and back side, to be staged domatic, and adopt geomembrane anti-seepage, dam body gos deep into both sides, river course basement rock 2m, the domatic slope ratio of staged is set to 1:2.5, the domatic of upstream face has two sections, one section connects riverbed plane, another section connects dam crest 2, these two sections domatic between connected by flat upper surface 3, the domatic of back side is one section, by hand excavation's reservoir beach ground, form irrigation canals and ditches 4, guide current, irrigation canals and ditches 4 width G reatT.GreaT.GT1m, the degree of depth > river wet season of irrigation canals and ditches 4 and the water-head in dry season, crystallizing field (being namely the large area beach because silt is formed) is separated into multiple Eco-Island 5 by irrigation canals and ditches 4, each Eco-Island 5 is planted respectively and is implanted with arbor, shrub or herbaceous plant, build and have high and low layered vegetable layer.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
