Embodiment 1

[0033] The invention provides a water diversion purification system of an artificial lake, such as Figure 1 ~ Figure 3As shown, a preferred embodiment of the present invention is shown therein. The diversion and purification system of the artificial lake water body of the present invention is divided into two parts, the water inlet area 2 and the purification confluence area, by the first gabion diversion dam 3 .

[0034] Specifically, the diversion purification system includes a first gabion diversion dam 3 arranged around the lake inlet 1 in the artificial lake water body, and the first gabion diversion dam 3 separates the artificial lake water body into water inlet Area 2 and the purification confluence area, aquatic plants are planted in the purification confluence area, and the first gabion diversion dam 3 includes a dam body 15 arranged on the bottom of the artificial lake water body and a backside of the dam body 15 The backwater slope 16 on the water surface, the slo...

Embodiment 2

[0046] The present invention also provides a construction method of a diversion purification system for an artificial lake water body, the construction method comprising the following steps:

[0047] A. Construct the first gabion diversion dam 3, wherein the gabion is made from the inside to the outside to complete the distribution of water purification filler, geotechnical bag, gabion net 15, and the gabion is stacked in layers to form the dam body 15, At the same time, gravel 14 is used to construct the backwater slope 16, and a permeable material layer 13 is laid on the slope surface of the backwater slope 16.

[0048] The area surrounded by the first gabion diversion dam 3 and the revetment into the lake is the water intake area, accounting for about 1 / 8 to 1 / 5 of the entire artificial lake. Gabions are stacked in layers, and each layer along the direction of water flow is gravel filler 10, zeolite and steel slag mixed filler 12, and backwater slope 16, and the number of s...

Abstract

The invention relates to a diversion and purification system for an artificial lake water body and a construction method thereof. The diversion and purification system comprises a first gabion diversion dam arranged inside the artificial lake water body and around a lake inlet, wherein the first gabion diversion dam divides the artificial lake water body into a water inlet area and a purificationand confluence area; aquatic plants are arranged in the purification and confluence area; the first gabion diversion dam comprises a dam body arranged at the bottom of the artificial lake water body and a downstream slope arranged on the downstream face of the dam body; a water-permeable material layer serves as the slope face of the downstream slope; rock ballasts are filled between the slope face of the downstream slope and the dam body; the dam body is formed by stacking gabions; each gabion comprises a gabion net as an external frame, a geotextile bag filled into the gabion net, and a water distributing and purifying filler filled into the geotextile bag. The diversion and purification system not only can promote circulation of the artificial lake water body in the whole lake area to purify water, but also can reduce the energy loss and enhance the landscape effect of an artificial lake.

Description

technical field [0001] The invention relates to the field of ecological environment, in particular to an artificial lake water diversion purification system and a construction method thereof, which is especially suitable for use in artificial lake water bodies with poor water flow capacity. Background technique [0002] Because of its important role in improving the urban water environment, beautifying the urban landscape, and enhancing the historical and cultural characteristics of the city, urban artificial lakes have been more and more widely used. Different from the natural flow fields and water ecosystems formed by natural lakes, urban artificial lakes have certain flexibility in terms of water supply and water cycle construction, but at the same time, they will also bring some uncertain consequences. For example, when the water cycle is constructed by transforming the river channel, factors such as the change of incoming water quality or the flow field are underestimat...
