Embodiment Construction

[0039] like figure 1 As shown, the present invention is an ecological bay based on a permeable dam, including a river 1 and a bay 2 protruding outward on one side of the river 1, and the connection between the bay 2 and the river 1 An ecological island 3 is set at the place, and a permeable dam 5 is set between the upstream side of the ecological island 3 and the river bank 7 . figure 1 The direction indicated by the middle arrow is from the upstream of channel 1 to the downstream of channel 1.

[0040] like Figure 5 As shown, the top of the permeable dam 5 is higher than the normal water level 1a of the river 1 and lower than the flood level 1b of the river 1 .

[0041] like Figure 4 , Figure 5 As shown, the middle of the top of the permeable dam 5 is downwardly provided with a housing chamber 51, and a plurality of artificial bio-barriers 51a are arranged inside the housing chamber 51; the side wall of the housing chamber 51 is a reinforced concrete permeable wall 52,...

Abstract

The invention discloses an ecological bay channel based on a permeable dike. The ecological bay channel based on the permeable dike comprises the permeable dike (5) arranged between the upstream sideof an ecological island (3) and a river bank (7) of a river channel (1). An accommodating chamber (51) is formed downwards in the middle of the top of the permeable dike (5), and a plurality of artificial biological grids (51a) are arranged inside the accommodating chamber (51). The side wall of the accommodating chamber (51) is a reinforced concrete permeable wall (52), and an ecological floatingbed (55) is arranged at the top of the accommodating chamber (51) in a covering mode. The artificial biological gates (51a) are arranged at the bottom of the ecological floating bed (55) in a hung mode. A bay channel body (2) is separated from a main channel body of the river channel (1) by the permeable dike (5) formed by piling up stone, and the water level of the bay channel body (2) is regulated by controlling the elevation of the top end of the permeable dike (5). During the flood season, flood water overflows to the bay channel body (2) through the top end of the permeable dike (5), andthe flood regulation and storage total amount of the river channel (1) can be increased; and after raining, since water is blocked by the permeable dike (5), the water velocity in the bay channel body (2) is much lower than that in the river channel (1), and a suitable place for aquatic animals to live and breed is provided.

Description

technical field [0001] The invention relates to the technical field of river improvement, in particular to a permeable dam in an ecological bay. Background technique [0002] Ecological Bay Road is used for river ecology and habitat restoration. In the floodplain of the river channel, a depression with a slower flow rate than the main channel is created to provide a place for fish and benthic organisms to survive and reproduce. [0003] As a protection strategy for river ecosystems, Eco Bay Road is an important environmental element. In recent years, due to the linearization of rivers and the transformation of river banks, aquatic organisms have not had a good environment for survival and reproduction, and have lost the diversity of river structures, resulting in uneven development of ecosystems. Therefore, in the planning of river improvement, it is very important to expand the environmental elements of its cross section. [0004] In order to solve the above problems, ou...
