A permeable ecological permeable overflow dam for water purification

Abstract

The invention discloses a permeable ecological permeable overflow dam for water purification, which comprises a dam foundation (1) made of concrete pouring, and a gabion piled up on the top surface of the dam foundation (1). An overflow dam (2), the gabion is filled with stones, the top of the overflow dam (2) is provided with a holding chamber (3) arranged along its length direction, the overflow dam (2 ) are respectively provided with retaining walls (4), and the retaining walls (4) are poured and fixed on the dam foundation (1). The invention guarantees the slow flow of the traditional permeable overflow dam, purifies the water quality and looks beautiful, and at the same time can make it have the function of water diversion, so that it can ensure the passability of the entire dam body in the flood season, and in normal times Can ensure the overall water storage.

Description

technical field [0001] The invention relates to the technical field related to water conservancy equipment, in particular to a permeable ecological permeable overflow dam for water purification. Background technique [0002] The overflow dam is a dam that can discharge flood without a gate on the top of the dam, also known as the rolling dam. The application in the city should also have the function of beauty and water purification. In order to achieve this purpose, the usual method is to use crushed stones combined with gabions to build an overflow dam in the middle of the landscape river. This kind of dam Since there is no adhesive between the stones in the steel wire gabion, the water permeability is better. The main purpose is to reduce the flow rate of the landscape river, and at the same time, it can also have the functions of filtering and waterlogging. In order to make the landscape The permeable overflow dam body in the river is not too abrupt and the dam body can ...

[0002] The overflow dam is a dam that can discharge flood without a gate on the top of the dam, also known as the rolling dam. The application in the city should also have the function of beauty and water purification. In order to achieve this purpose, the usual method is to use crushed stones combined with gabions to build an overflow dam in the middle of the landscape river. This kind of dam Since there is no adhesive between the stones in the steel wire gabion, the water permeability is better. The main purpose is to reduce the flow rate of the landscape river, and at the same time, it can also have the functions of filtering and waterlogging. In order to make the landscape The permeable overflow dam body in the river is not too abrupt and the dam body can also be aesthetically pleasing. At present, there is a kind of accommodating cavity arranged along its length direction reserved on the top of the permeable overflow dam when pouring and forming. , a floating bed is set in the holding chamber, and some aquatic plants are planted on the floating bed, and the aquatic plants are used to filter the water flowing through the holding chamber. The overall drainage performance in the water season is poor
