Description

Technical Field

[0001] The utility model relates to the technical field of reverse filter layers, in particular to a multi-layer woven cloth sand belt soft reverse filter layer suitable for water-carrying construction. Background Art

[0002] In water conservancy projects, geotextiles are mostly used as filter layers for embankments, rivers, coasts, slope protection, retaining walls, etc., which prevent soil particles from passing through while allowing water or gas to pass freely.

[0003] The laying construction of geotextiles is mostly required to be carried out under dry land conditions. However, when dry land construction conditions cannot be met, the geotextile is relatively light and cannot sink to the bottom by itself, so the geotextile cannot be laid as designed and meet the requirements. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the above-mentioned background technology and provide a multi-layer woven cloth sand belt soft filter layer suitable for water-carrying construction. The filter layer has a simple structure and can sink to the bottom by itself. The construction is simple and efficient, and the requirements of reverse filtration are met at the same time.

[0005] In order to achieve the above-mentioned purpose, the utility model is designed to be suitable for water-carrying construction. The utility model comprises a multi-layer woven cloth sand belt soft filter layer, which comprises a filter layer body, wherein the filter layer body comprises at least two layers of woven cloth stacked together; a plurality of sand belts are sewn at intervals around the filter layer body and along the direction of the water flow, and the sand belts are filled with sand;

[0006] The filter layer body is also provided with a plurality of continuous reinforced anchoring belts sewn at intervals along the direction of the water flow, and a plurality of reinforced belt pull rings are sewn around the filter layer body.

[0007] As a preferred embodiment, a tubular filling cuff is provided on the sand belt on the filter layer body near the estuary side edge.

[0008] As a preferred embodiment, both sides of the abrasive belt are sewn on the filter layer body using nylon thread to form sewing lines.

[0009] As a preferred embodiment, the width of the sanding belt is 300-500 mm.

[0010] As a preferred embodiment, the reinforced anchor belt is a polypropylene reinforced belt, and the width of the reinforced anchor belt is 50-60 mm.

[0011] As a preferred embodiment, the reinforcement belt pull ring adopts a polypropylene reinforcement belt, and the width of the reinforcement belt pull ring is 50-60mm.

[0012] As a preferred embodiment, the filter layer body is formed by stacking two layers of woven fabric, a first woven fabric and a second woven fabric.

[0013] As a preferred embodiment, the spacing distance between two adjacent sand belts of the filter layer body along the direction of water flow is less than or equal to the spacing distance between two adjacent reinforced anchor belts.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] Firstly, compared with the commonly used sand rib soft-body row, gravel bag soft-body row and mixed soft-body row, the multi-layer woven cloth sand belt soft-body row filter layer construction of the utility model suitable for water construction does not require a special laying ship, and the construction is convenient and efficient.

[0016] Secondly, the utility model aims at the situation that the geotextile cannot sink to the bottom when laid directly with water. After the anti-filtration layer is processed according to the requirements, it only needs to be positioned with anchors or small ships, and then filled with sand after positioning, so that it sinks to the bottom and meets the laying requirements of the anti-filtration layer.

[0017] Thirdly, the multi-layer woven cloth abrasive belt soft drainage filter layer of the utility model is suitable for water-carrying construction, has low cost and can adapt to various working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1 to Figure 3As shown, the utility model is a multi-layer woven cloth sand belt soft filter layer suitable for water construction, comprising a filter body 1, the filter body 1 is composed of at least two layers of woven cloth superimposed; a plurality of sand belts 2 are sewn at intervals around the filter body 1 and along the direction of the water flow, and the sand belts 2 are filled with sand bodies; a plurality of full-length reinforced anchor belts 3 are also sewn at intervals along the direction of the water flow on the filter body 1, and a plurality of reinforced belt pull rings 4 are sewn around the filter body 1. A tubular filling cuff 5 is provided on the sand belt 2 near the estuary side edge of the filter body 1. Both sides of the sand belt 2 are sewn on the filter body 1 with nylon thread to form a sewing line 6. The width of the sand belt 2 is 300-500mm. The reinforced anchor belt 3 is a polypropylene reinforced belt, and the width of the reinforced anchor belt 3 is 50-60mm. The reinforcing belt pull ring 4 is made of polypropylene reinforcing belt, and the width of the reinforcing belt pull ring 4 is 50-60mm. The spacing distance between two adjacent sand belts 2 of the filter layer body 1 along the downstream direction is less than or equal to the spacing distance between two adjacent reinforcing anchor belts 3.

[0028] In this embodiment, the filter body 1 is made of two layers of woven fabrics, the first woven fabric 11 and the second woven fabric 12. Sand belts with a width of 300 mm are sewn at a certain distance along the direction of the water flow and around the edges as needed for filling sand. Reinforced anchor belts are set at a certain distance along the edges and along the direction of the water flow for anchoring and positioning. This is suitable for setting up a filter layer that cannot be constructed on dry land. Sand filling ports are reserved on the edge of the sand belt 2 on the estuary side of the filter body according to the convenience of construction. Full-length reinforced anchor belts 3 are sewn at a certain distance along the direction of the water flow. Reinforced belt pull rings 4 are sewn at a certain distance around the edges for anchoring and positioning. After positioning and fixing, sand is filled into the sand belt through the filling cuffs 5, so that the two layers of woven fabrics settle in place by the deadweight of the filled sand body. Compared with the commonly used sand rib soft-body row, gravel bag soft-body row and mixed soft-body row, the anti-filter layer of the utility model does not require a special laying ship for construction, and the construction is convenient. For the situation where the geotextile laid directly with water cannot sink to the bottom, the anti-filter layer of the utility model only needs to be positioned with an anchor or a small ship after processing according to the requirements, and then filled with sand after positioning, so that it sinks to the bottom and meets the laying requirements of the anti-filter layer. Compared with the existing technology, the anti-filter layer of the utility model is simple to construct, low in cost and can adapt to various working conditions.

[0029] The above are only specific implementation methods of the present invention. It should be pointed out that any changes or substitutions that can be easily thought of by any technician familiar with the field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention, and the rest not described in detail belong to the prior art.
