Description

Technical Field

[0001] The utility model relates to the technical field of artificial wetlands, in particular to a graded waterfall stepping stone for surface flow wetlands. Background Art

[0002] Constructed wetlands are controllable, engineered water treatment systems designed and constructed to mimic natural wetlands. They utilize the synergistic effects of physical, chemical, and biological processes within the system to purify water. They are a key technological tool for rainwater storage, runoff treatment, tailwater ecological purification, and surface water quality improvement. To maximize the multiple functions of wetland systems and reduce construction costs, surface flow constructed wetlands (also known as surface flow wetlands) are generally preferred in sponge city construction.

[0003] Due to the geographical differences in height within wetlands, single or multiple steps of waterfall stepping stones are arranged according to the drop in the water, dividing the surface flow wetland into different levels. Each level of surface flow wetland is demarcated by a waterfall stepping stone. Stepping stones are a type of stepping stone, arranged at regular intervals in shallow water, slightly exposed above the surface, creating an aesthetically pleasing landscape and a waterway. Existing waterfall stepping stones have the following problems: 1. Further water purification facilities are lacking within the waterfall stepping stone interception area; 2. Once the waterfall stepping stone has a fixed height, raising it is complex and cumbersome. Utility Model Content

[0004] The purpose of the utility model is to provide a graded waterfall stepping stone for surface flow wetlands with a reasonable structure and reliable use to solve the above problems. The utility model is convenient for adjusting the height and has a wide range of applications. At the same time, an aeration structure is added to enhance the water purification degree.

The hand gate includes two vertical rails, a gate plate arranged between the two vertical rails, and a handle arranged on the top of the gate plate.

[0009] The above-mentioned graded waterfall stepping stone for surface flow wetland has a supporting foundation of a mortar masonry layer, and a cement mortar layer is provided on the surface of the mortar masonry layer.

[0012] 1. An aeration structure is provided on the upper surface of the horizontal section of the supporting foundation. When in use, oxygen is introduced into the aeration structure through the air inlet pipe. The oxygen is exposed to the waterfall stepping interception area through the aeration port to further purify water resources.

[0013] 2. An inverted U-shaped cover plate is installed on the top of the vertical section of the support base. When the height of the entire waterfall step needs to be adjusted, the inverted U-shaped cover plate is lifted to raise or lower the height of the support base, and then the inverted U-shaped cover plate is replaced, eliminating the need to reinstall the stepping platform. This convenient operation and height adjustment are convenient and widely applicable, while ensuring the stability of the stepping platform. The sealing layer between the inverted U-shaped cover plate and the support base also prevents water from flowing through the seam. BRIEF DESCRIPTION OF THE DRAWINGS
