CN216194409U - Mountain stream property flood-carrying ecological river channel section form with anti-seepage function - Google Patents

Abstract

The utility model discloses a mountain stream flood-carrying ecological river channel section type with an anti-seepage function, which comprises a river bed and a river channel formed by downward excavation along the outer edge of the river bed, wherein a landscape footpath, a bank slope and a bank top are sequentially arranged on one side of the river channel, which is far away from the river channel, outwards. In the dry season, the amount of the water coming from the river channel is small, and the water flow enters the river channel subjected to anti-seepage treatment, so that the ecological and landscape water level can still be ensured, and a better hydrophilic effect is achieved; a small amount of anti-impact landscape stone is arranged on the riverbed, so that the originally exposed dry riverbed has better appearance. In the flood season, the river channel, the beach river bed and the two bank dykes form a wide flood section, and share the flood function, so that the flood safety requirement of the river channel can be effectively guaranteed; the method is more suitable for mountain stream river channels with small water amount in the dry season and large flood peak amount in the flood season.

As a preferred technical scheme of the utility model, the bank slope adopts ecological anti-impact slope protection materials for bank protection.

As a preferable technical scheme of the utility model, the elevation of the top of the dike is higher than the river water level in the flood season.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. in the dry season, the amount of the water coming from the river channel is small, and the water flow enters the river channel subjected to anti-seepage treatment, so that the ecological and landscape water level can still be ensured, and a better hydrophilic effect is achieved; plants with better landscape are planted in the beach land, so that the originally naked dry riverbed has better appearance.

2. In the flood season, the river channel, the beach river bed and the two bank dykes form a wide flood section, share the flood function and can effectively guarantee the flood safety requirements of the river channel.

3. The method is more suitable for mountain stream river channels with small water amount in the dry season and large flood peak amount in the flood season.

Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present invention, the following description of the preferred embodiments of the present invention is provided in conjunction with specific examples, but it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.

The utility model will be further described with reference to the accompanying fig. 1 and examples, but is not to be construed as being limited thereto.

As shown in fig. 1, the present embodiment provides a section pattern of a mountain stream ecological river with an anti-seepage function, which includes a river channel 1, an anti-seepage layer 2, a river bed 3, a landscape footpath 4, a bank slope 5 and a bank top 6. The river channel 1 is formed by downward excavation along the edge of the river bed 3, the impermeable layer 2 is laid in the river channel 1, the landscape footpath 4 is arranged close to the outer edge of the river channel 1, and the landscape footpath 4 is outwards provided with a bank slope 5 and a dike top 6 in sequence.

In the embodiment, the cross section of the river channel 1 is in an inverted trapezoid shape, and the width and the depth of the cross section are determined according to the average flow of the river channel in the dry period; and in the dry period, the inflow amount of the river is small, and the water level of the river is consistent with the elevation of the bottom 3 of the river bed and is 20-50 cm lower than the landscape footpath. In the dry season, the amount of water coming from the river channel is small, and water flows enter the river channel 1 after anti-seepage treatment, so that the ecology and landscape water level can still be guaranteed, and a good hydrophilic effect is achieved; plants with better landscape are planted in the beach land, so that the originally naked dry riverbed has better appearance. In the flood season, the river channel 1, the beach river bed and the two bank dykes form a wide flood-running section, share the flood-running function, and can effectively guarantee the flood-running safety requirements of the river channel.

Furthermore, an impermeable layer 2 is laid in the river channel 1, and the impermeable layer can be laid according to local conditions according to the geological condition of the river channel, so that the river channel in the dry season still keeps stable water level, and the ecological and landscape effects are better.

In the embodiment, the riverbed 3 is exposed outside in the dry season, and a plurality of anti-impact landscape placing stones 7 are arranged on the riverbed 3; in the flood period, the riverbed 3 can be used as a main flood passage of the riverway.

In this embodiment, the landscape footpath 4 is arranged between the river channel 1 and the bank slope 5; the top elevation of the landscape footpath 4 is 20cm-50cm higher than the water level of the riverway in the dry season, so that the landscape footpath has a good hydrophilic effect.

In this embodiment, the bank slope 5 is connected to the landscape footpath 4 and the bank top 6, and the bank slope 5 can be made of ecological anti-impact slope protection material for bank protection. The elevation of the bank top 6 is determined according to the elevation of the design bank top required by the river channel, and the width of the bank top 6 is determined according to the actual river channel bank level and other relevant factors.
