Full-enclosed type flexible deepwater enclosure

Abstract

A totally enclosed flexible deep water enclosure can effectively separate open water body. The main body comprises a flexible bar shape floating body, a cork rope, a wall cloth, a ground rope, and a stone dragon. The stone dragon is buried in a sealed close bottom end of a silt layer, and the flexible bar shape floating body floats on the water to form separation. A mooring cable is used for fixing the ground rope on two under water wood piles at two sides, preserving degree relaxation in the vertical and horizontal directions. An under water anchoring mooring cable, the ground rope, a wall cloth longitudinal stiffening rib, and the cork rope constitutes the network-shape mechanics structure of the enclosure. The flexible bar shape floating body uses a flue to wrap a flexible closed-hole foam plastic strip, and the outside is protected by a changeable coating for structural durability. The enclosure subsections are connected by zipper fashion blanket stitches, convenient for processing, transportation, installation, dissembling, maintenance, and reuse, and can be used for contemporary separation of part water areas of the open water body, such as the boundary control of water surface project area, the separation and diversion of polluted water mass. The invention is suitable for natural conditions such as deep water (10m above), storm, water current, water level fluctuating, with the service life of 5-10 years.

Description

Technical field: [0001] Water environment engineering, auxiliary (environmental protection) engineering of water engineering. The invention relates to a fully enclosed flexible deep-water enclosure, which is suitable for temporary separation of inland low-velocity water bodies (lakes, reservoirs, plain rivers), such as isolation of locally polluted waters, boundary control of water construction areas, and water surface water quality. Boundary control of purification works, etc. Background technique: [0002] At present, the known temporary separation engineering technologies for inland low-velocity water bodies are as follows: (1) Temporary dikes, built with sand bags or filled with geotechnical bags, suitable for shallow water (generally less than 3m), The cost of construction and demolition increases exponentially with the increase of water depth, and a large amount of sand and soil needs to be transported, which takes a long time for on-site construction; (2) The rigid b...

Problems solved by technology

[0002] At present, the known temporary separation engineering technologies for inland low-velocity water bodies are as follows: (1) Temporary dikes, built with sand bags or filled with geotechnical bags, suitable for shallow water (generally less than 3m), The cost of construction and demolition increases exponentially with the increase of water depth, and a large amount of sand and soil needs to be transported, which takes a long time for on-site construction; (2) The rigid body skeleton supports the shallow water enclosure of membrane water-proof material, which is suitable for small static water bodies with a water depth of less than 2m; ( 3) Floating enclosures (non-enclosed) in the surface water layer are mainly used to control the diffusion and migration of floating pollutants (petroleum, blue-green algae, etc.), and the isolation performance is poor. The effect of isolating blue-green algae in Dianchi Lake from 2000 to 2004 was very poor (4) The fully enclosed flexible shallow water enclosure is widely used in shallow lakes or shallow water areas along the coast, generally limited to less than 3m water depth, and is easily damaged when encountering strong wind and waves, and the segmented rigid floating body (rigid foam plastic cylinder) is easy to wear Broken jacket, poor isolation at the joints, and the overall service life does not exceed 3 years. It was used for boundary protection in the water source area of ​​Taihu Lake from 2002 to 2005, and was severely damaged by wind and waves.

So far, there is still a lack of fully enclosed flexible enclosures suitable for open water (wind and wave heights greater than 1m) and deep water areas (above 5m) with an effective service life of more than 5 years
