Float-type surface water draining device and method

Abstract

The invention discloses a float-type surface water draining device and method. The device comprises a float ring and a drainage filter body; the centre of the float ring is provided with a cylindrical cavity; the float ring is provided with a mooring ring; the drainage filter body is a cylindrical framework; the external diameter of the drainage filter body is equal to the radius of the cylindrical cavity; the drainage filter body is internally provided with a plastic blind groove as a bracket; the bottom of the drainage filter body is provided with a permeable filter material layer; a sealing layer is covered on the outer part other than the bottom side; and the top is provided with a soft vacuum pipeline for connecting the inside of the drainage filter body with a vacuum source. The float-type surface water draining device can be used for solving the problem that the surface water can not be extracted under the condition that water can not be drained by a regular drainage device in sludge storage yards or hydraulic fill spaces by absorbing water on the sludge surface through the soft vacuum pipeline, and has the advantages of simplicity in operation, high efficiency and low drainage cost.

Description

technical field [0001] The present invention relates to a floating surface water drainage device and method for pumping out surface water used in silt storage yards and dredging land reclamation sites. The utility model relates to a drainage device designed to float and extract surface water when conventional drainage equipment cannot be used for drainage construction, and belongs to related technical fields such as geotechnical engineering and environmental engineering. Background technique [0002] In river dredging and dredging projects and sea reclamation projects, the problem of dredging and filling consolidation of soil with high water content will be encountered. For the site filled with high water content silt, a layer of surface water layer with a certain thickness will be formed in a short time, and the soil below the water layer still maintains a high water content, even a level close to the initial semi-fluid state; in the case of such a surface water layer and ...
