Geotechnical reinforcement protective filter material

Abstract

The invention discloses a geotextile reinforced protecting reverse filtering material and a geotextile reinforced reverse filtering construction method and a bridge pier protecting construction method thereof. The geotextile reinforced protecting reverser filtering material comprises geotextile fabrics and a skeleton, wherein the skeleton is fixedly connected with at least one layer of geotextile fabric. The invention also discloses the geotextile reinforced reverse filtering construction method of the geotextile reinforced protecting reverse filtering material and the bridge pier protecting construction method of the geotextile reinforced protecting reverse filtering material. The geotextile reinforced protecting reverse filtering material has the advantages that the structure is simple, the splicing is convenient, and the paving is easy; by utilizing the characteristics of large contact area of the geotextile fabric and high strength and dispersed stress of the skeleton, the stress of large stone blocks is dispersed, so the sand stones can integrally settle, and the stone throwing uniformity is realized; and in the bridge pier protection, the material is covered on the water flow flushing area at the periphery of a bridge pier, so the shock energy of the water flow is reduced, the reverse filtering function of the geotextile fabric is utilized, the soil grains under the covering surface cannot be flushed away by the water flow, and the shock on the bridge pier by the foreign matters is reduced by utilizing the elasticity of the geotextile reinforced protecting reserve filtering material with enhanced mechanical property on the bidirectional-tension plastic geotextile grid skeleton.

Description

technical field [0001] The invention belongs to the technical field of geotechnical materials, and in particular relates to a geotechnical reinforced protective anti-filter material, a geotechnical reinforced anti-filter construction method and a bridge pier protection construction method. Background technique [0002] Composite geotextiles are also called soft fabrics. The upper layer of the soft body row is a filter geotextile layer, and the lower layer is a woven fabric layer. Several units are sewn between the upper and lower layers. The periphery of each unit body is filled with sand to form a grid shape with main ribs and auxiliary ribs. , the main ribs are perpendicular to the direction of water flow, and the auxiliary ribs are along the direction of water flow. At present, composite geotextiles have been widely used in land reclamation and bridge pier protection. Due to the good flexibility of the composite geotextile soft row, it can automatically adjust the overa...

Problems solved by technology

However, when the water flow is fast, the discharge will generate underwater agitation, thus emptying the sediment under the discharge body, losing its protective function, and even being washed away by the current. Although the soft discharge is a better bottom protection and filter material, it can adapt to the river bed The change of the bed surface plays the role of overall anti-seepage and bottom protection, but it does not have a good effect on the address and hydrological conditions of large water volume, high flow velocity, serious erosion, and deep silt layer.
