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
The invention belongs to the earth working material technical field, be specifically related to Earthworking reinforced bar protection filtration material and geotechnique thereof and reinforce anti-filter job practices and Bridge Pier job practices.
Background technology
Composite earthwork cloth also is soft raft.The upper strata of soft raft is anti-filter geotechnique layer of cloth, lower floor is woven layer of cloth, upper and lower is sewn into some cell cubes between two-layer, and each cell cube periphery charges sand and forms the sash shape with main rib and auxiliary rib, its main rib is perpendicular to water (flow) direction, and auxiliary rib is along water (flow) direction.At present composite earthwork cloth reclaim land from the sea and Bridge Pier in be widely applied.Because complex geotechnical textile soft row shape matter for filling sand has good flexibility, in the jackstone process, can automatically regulate whole shape, form the ability of good guard wire and carrying stone, there is certain shore protection, river bottom protection function.But floating, the gauffer of meeting in construction, inconvenience is used; In the jackstone process, due to the softness of soft raft self, can make material because weight is former thereby sink in mud, do not have respective action.When composite earthwork cloth is applied to Bridge Pier, sand pocket and soft raft etc. can be resisted the downward whirlpool that the preshoot of bridge pier pier is struck waters and miscarried and give birth to, and to reach the effect that obviously reduces the pier foundation scour depth, and is protected around can reaching pier footing.But when current are very fast, isostere can produce under water and agitate, thereby wash in a pan the silt under empty isostere, lose safeguard function, even washed away by current, although though soft raft is river bottom protection filtration material preferably, can adapt to River Bed and change the whole antiseepage river bottom protection effect of playing, but large for the water yield, flow velocity is large, washes away address and hydrological regime serious, the mud layer depth and do not have good effect.
