Deepwater ecological pond
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.
本发明涉及生态堰塘技术领域，公开了一种深水生态堰塘，包括塘体，塘体包括基础层、设置在基础层上的防渗层和设置在防渗层上的保护层，塘体包括深水区和浅水区，深水区底部到浅水区上端的垂直高度大于2.5m，深水区的防渗层包括钠基膨润土防渗毯，浅水区的防渗层包括防渗黏土层；深水区底部设有调节渗透装置，调节渗透装置包括混凝土围堰、金属筒和浮体，混凝土围堰内侧的防渗层为防渗黏土层，金属筒固定在混凝土围堰上，金属筒的顶部设有开孔；本发明提供的一种深水生态堰塘，能够适应高水位的防渗需求，与此同时也能够满足低水位状态下，保证适当渗漏率，适应低水位的防渗需求，所以不影响地表水与地下水的双向调节，使塘体具有自净能力。
