Problems solved by technology

Past reclamation projects have added foreign soil or gravel to the seabed nearby. After the seabed landform is damaged, it is easy to pollute the seawater under the repeated washing of waves, making the seawater turbid and affecting the ecology. If there is a breeding area in the surrounding area, the impact will be even more serious , the loss is immeasurable

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] Such as figure 1 , 2 Shown, a kind of anti-filter grille, it mainly comprises geotextile 1, and described geotextile 1 is provided with grid layer 2 with well shape above, described grid layer 2 above is provided with anchor hole 2a, and adopts bolt The geotextile 1 and the mesh layer 2 are fastened and connected. The thickness of the geotextile 1 is 2-10mm, the geotextile 1 is made of polypropylene or polyester material, the thickness of the grid layer 2 is 1-5mm, and the width is 50-100mm. The layer is made of polypropylene or polyethylene material.

[0015] The invention has the advantages that: the reverse filter grid can prevent seabed silt from being taken away by seawater, prevent seawater from being turbid, and reduce pollution to surrounding environment of reclamation area. In addition, the grid layer has high strength and large modulus, and plays the ro...

Abstract

The invention belongs to the technical field of geosynthetics and provides an inverted filter grille. The inverted filter grille mainly comprises geotextile. A #-shaped gridding layer is arranged on the geotextile. Anchor holes are formed in the gridding layer. The geotextile and the gridding layer are fastened and connected through bolts. According to the inverted filter grille, seabed sludge can be prevented from being taken away by sea water, sea water is prevented from becoming turbid, and pollution of surroundings of a reclamation area is reduced. In addition, the gridding layer is large in strength and modulus and capable of achieving the function of ribs.

Description

technical field [0001] The invention relates to an anti-filter grid, which belongs to the technical field of geosynthetic materials. Background technique [0002] At present, with the development of engineering construction in my country, higher requirements are put forward especially for the construction materials of the cofferdam in the reclamation project and the treatment of sea silt around the reclamation area. Past reclamation projects have added foreign soil or gravel to the seabed nearby. After the seabed landform is damaged, it is easy to pollute the seawater under the repeated washing of waves, making the seawater turbid and affecting the ecology. If there is a breeding area in the surrounding area, the impact will be even more serious , the loss is immeasurable. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the object of the present invention is to provide an anti-filter grille. The anti-filter grille can prevent se...
