Abstract

The utility model discloses an ecological floating bed for slope protection for the water-level-fluctuating zone of a reservoir. The ecological floating bed is characterized by comprising a piece of planting net, floating balls and fixing piles, wherein the floating balls are tied to the edge of the planting net; the upper end of the planting net is connected together with the fixing piles; and a plurality of such ecologic floating beds can be connected together for use through connection holes. Herbaceous plants capable of growing in water as well as on dry land are selected and planted on the floating bed, so as to form a grass blanket. In dry seasons, the floating bed covers the water-level-fluctuating zone of the reservoir to improve landscape and prevent water loss and soil erosion; and in wet seasons, the floating bed floats on shore water and can absorb nitrogen, phosphorus and other nutrient substances in the water to weaken the eutrophication of the water body of the reservoir area.

Description

The floating bed of reservoir drawdown band slope protection ecologic

Technical field

The utility model relates to a kind of biological floating bed, more particularly, is the floating bed of slope protection ecologic that a kind of reservoir drawdown band is used.

Background technology

The reservoir drawdown band is claimed the falling zone again, is the distinctive a kind of phenomenon of reservoir, is meant that the seasonal fluctuation in stage of reservoir makes the reservoir area be submerged soil periodicity exposure in the zone of the water surface.Expert's research is thought; Before the falling zone forms; The vegetation that is grown in the two sides, reservoir area is one natural ecological protective screen; To from the pollution of storehouse bank particularly widespread pollution from the overuse of fertilizers and pesticides in rural area play certain interception and filtering function, quite a few is digested and assimilated the nitrogen that surface flow carries, phosphorus etc. by vegetation, prevents to get into the reservoir area water body.And after the falling zone formed, the vegetation that disappears disappeared basically, the dry season; The falling zone exposes at the water surface, hinders view, receives the etch of rainwater and water wave; Severe water and soil erosion, even cause the bank body to cave in, the falling zone vegetation disappears; Pollution interception and filtering function to from the storehouse bank disappear, and more pollutant such as the nitrogen that surface flow carries, phosphorus will get into water body, cause reservoir area eutrophication degree to increase the weight of day by day.

The utility model content

The purpose of the utility model be to provide a kind of be used for the reservoir drawdown band bank protection is arranged, prevent erosion, tackle and purifies the surface flow pollutant; Absorb in the water nutriments such as nitrogen phosphorus, reduce function such as reservoir eutrophication and have the biological floating bed of ornamental value simultaneously again.

For realizing above-mentioned purpose, the utility model has adopted following technical scheme:

A kind of reservoir drawdown band is biological floating bed, it is characterized in that: be made up of plantation net, ball float and spud pile, the plantation selvage is along being tied with ball float; There is connecting hole at the edge; Can pass with spud pile with rope and be held together, through connecting hole, can also be with a plurality of so biological floating bed uses that link together.

Described ball float can difference on demand be tied up a plurality of arbitrarily.

The utlity model has following beneficial effect:

(1) protection reservoir drawdown band reduces soil erosion, improves reservoir drawdown band view, the pollutant in the surface flow of interception and purification storehouse bank;

(2) nutriments such as the nitrogen in the absorption water body, phosphorus reduce the big degree of body eutrophication.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is plant figure on the utility model kind;

Falling zone sketch map when Fig. 3 hangs down for the utility model is installed in water level;

Fig. 4 is installed in the falling zone sketch map of water level when high for the utility model.

Wherein, the 1-kind is planted net, 2-connecting hole, 3-rope, 4-spud pile, 5-ball float.

The specific embodiment

Like Fig. 1, shown in Figure 2; The floating bed of a kind of reservoir drawdown band slope protection ecologic is characterized in that: be made up of plantation net 1, ball float 5 and spud pile 4, plantation net 1 edge is tied with ball float 5; There is connecting hole 2 at the edge; Can pass with spud pile 4 with rope 3 and be held together, through connecting hole 2, can also be with a plurality of so biological floating bed uses that link together.

Described ball float 5 can difference on demand be tied up a plurality of arbitrarily.

As shown in Figure 3, when the lake water water level is lower, the reservoir drawdown band is biological floating bed just to be dropped on the falling zone through spud pile 4, has fabulous ornamental value; As shown in Figure 4, when lake water water level rising, the biological floating bed ball float 5 in falling zone can lift whole floating bed, prevents that top vegetation is submerged.

Can grow in a kind of water of the biological floating bed main plantation of this reservoir, the herbaceous plant that also can grow in the nonirrigated farmland is as a careless blanket.

Claims

1. a reservoir drawdown band is biological floating bed; It is characterized in that: constitute by plantation net (1), ball float (5) and spud pile (4); Plantation net (1) edge is tied with ball float (5), and there is connecting hole (2) at the edge, can use rope (3) to pass with spud pile (4) and be held together; Through connecting hole (2), can also be with a plurality of so biological floating bed uses that link together.

2. a kind of reservoir drawdown band according to claim 1 is biological floating bed, it is characterized in that: described ball float (5) can difference on demand be tied up a plurality of arbitrarily.
