Sandy soil cofferdam system used in still water drainage basin and construction method thereof
The invention provides a sandy soil cofferdam system used in a still water drainage basin. The sandy soil cofferdam system used in the still water drainage basin comprises a sandy soil cofferdam and soil non-diffusion mechanisms. The sandy soil cofferdam comprises a soil cofferdam body, a two-cloth one-membrane and soil bags. The water side of the soil cofferdam body is covered with the two-clothone-membrane. The outer side of the two-cloth one-membrane is covered with the soil bags. The soil non-diffusion mechanisms are arranged on the upstream and downstream of the sandy soil cofferdam correspondingly. Each soil non-diffusion mechanism comprises an antifouling curtain, a buoy, suspension dropping bodies and counter weights, wherein the two opposite ends of the antifouling curtain are fixed to the two banks of a river channel; the buoy is mounted on the top of the antifouling curtain; the suspension dropping bodies are mounted at the bottom of the antifouling curtain; the bottom of the antifouling curtain is spaced from the bottom of the river channel; the counter weights are arranged on the upstream side and the downstream side of the antifouling curtain correspondingly; the counter weights are used for being mounted at the bottom of the river channel and are connected with the top of the antifouling curtain through lifting chains. Through the sandy soil cofferdam system, pollution of soil to water can be reduced during cofferdam construction. The invention further provides a construction method of the sandy soil cofferdam system.
本发明提供一种用于静水流域中的砂性土围堰系统，包括砂性土围堰及土壤防扩散机构，砂性土围堰包括土围堰主体、二布一膜及土袋，二布一膜覆盖于土围堰主体的亲水侧，土袋覆盖于二布一膜的外侧；砂性土围堰的上下游侧均设有土壤防扩散机构，每一土壤防扩散机构包括防污帷幕、浮标、悬坠体及配重件，防污帷幕的相对两端固定在河道两岸，浮标装设于防污帷幕的顶部，悬坠体装设于防污帷幕的底部，防污帷幕的底部与河道底部间隔设置；防污帷幕的上游侧及下游侧均设有配重件，配重件用于置于河道的底部并通过吊链与防污帷幕的顶部连接。该砂性土围堰系统能够减弱围堰施工过程中土壤对水体的污染。本发明还提供该砂性土围堰系统的施工方法。
