Problems solved by technology

[0004] Due to the influence of climate and other environmental factors, ponds with a design water depth greater than 2.5m will also have a low water level for a long time, or even drop below 2.5m. If the low water level remains for a long time, the overall pond The anti-seepage design using sodium bentonite anti-seepage blanket cannot meet the anti-seepage requirements of low water level

Embodiment 1

[0040] Such as Figure 1-Figure 3 As shown, the present embodiment provides a deep-water ecological weir pond, including a pond body 1, and the pond body 1 includes a base layer 2, an anti-seepage layer 3 arranged on the base layer 2 and a protective layer 4 arranged on the anti-seepage layer 3 , the pond body 1 includes a deep water area 5 and a shallow water area 6, the vertical height from the bottom of the deep water area 5 to the upper end of the shallow water area 6 is greater than 2.5m, the anti-seepage layer 3 of the deep water area 5 includes a sodium-based bentonite anti-seepage blanket 3, and the vertical height of the shallow water area 6 The anti-seepage layer 3 includes an anti-seepage clay layer 15; the bottom of the deep-water area 5 is provided with a seepage-adjusting device, which includes a concrete cofferdam 7, a metal cylinder 8 and a floating body 9, and the anti-seepage layer 3 inside the concrete cofferdam 7 is an anti-seepage The clay layer 15, the me...

Embodiment 2

[0045] This embodiment is optimized and defined on the basis of the above-mentioned embodiment 1.

[0046] In order to adjust the floating position of the floating body 9 as required, so that the upper end surface of the floating body 9 is flush with the interface between the deep water area 5 and the shallow water area 6 when the stay rope 10 is tensioned, the floating body 9 is a hollow metal ball or a hollow metal cylinder.

[0047] The weight of the floating body 9 can be adjusted by filling the hollow metal ball or the hollow metal cylinder with water, thereby adjusting the suspension position of the floating body 9 .

[0048] It should be noted that the floating position of the floating body 9 can also be adjusted by adjusting the length of the stay rope 10 .

Embodiment 3

[0050] This embodiment is optimized and defined on the basis of the above-mentioned embodiment 2.

[0051] In order to better realize the fixed pavement of the sodium-based bentonite anti-seepage blanket 3, an anchoring ditch 13 is excavated circumferentially at the junction of the deep water area 5 and the shallow water area 6, and the sodium-based bentonite anti-seepage blanket 3 is close to the wall of the anchoring ditch 13 and the bottom of the ditch, and then backfill the soil body for compaction, and the width and depth of the bottom of the anchor ditch 13 are greater than or equal to 500mm.

Abstract

The invention relates to the technical field of ecological ponds and discloses a deepwater ecological pond which comprises a pond body; the pond body comprises a base layer, an impervious layer arranged on the base layer and a protective layer arranged on the impervious layer; the pond body comprises a deepwater area and a shallow water area; the vertical height from the bottom of the deepwater area to the upper end of the shallow water area is greater than 2.5 m; the impervious layer of the deepwater area comprises a sodium bentonite geosynthetic clay liner; the impervious layer of the shallow water area comprises an impervious clay layer; a permeation adjusting device is arranged at the bottom of the deepwater area and comprises a concrete cofferdam, a metal cylinder and a floating body;the impervious layer on the inner side of the concrete cofferdam is an impervious clay layer; the metal cylinder is fixed on the concrete cofferdam; and a hole is formed in the top of the metal cylinder. The deepwater ecological pond can be adapted to the high water level impervious demand, also can ensure a proper leakage rate in the low water level state, is adapted to the low water level impervious demand, does not affect bidirectional adjustment of surface water and underground water and enables the pond body to have the self cleaning capacity.

Description

technical field [0001] The invention relates to the technical field of ecological weir ponds, in particular to a deep-water ecological weir pond. Background technique [0002] The existing concrete hardening treatment at the bottom of the pond will affect the two-way regulation of surface water and groundwater, and the pond body will become stagnant water with poor self-purification ability. Seepage layer, and according to the difference in anti-seepage requirements, clay and sodium bentonite anti-seepage blankets are selected, both clay and sodium bentonite anti-seepage blankets can ensure an appropriate leakage rate, and both have self-purification capabilities of water. [0003] However, the existing anti-seepage design is mainly suitable for ponds that can maintain a specific water level, that is, when the design water depth of the pond is less than 2.5m, clay anti-seepage design will be adopted; when the design water depth of the pond is greater than 2.5m, sodium-based ...
