Method for banking with silt filled geotextile bags

Abstract

The invention discloses a method for banking with silt filled geotextile bags, and relates to dike construction. Silt, the geotextile bags, plastic drainage plates and precipitation wells are used for constructing a dike; the method is characterized in that the content of particles of which the particle size is greater than 0.075mm in the silt do not exceed 50 percent of the total mass; side faces of the geotextile bags are made of composite geotextiles, and upper and lower surfaces of the geotextile bags are made of woven fabrics; two sides of the dike are provided with prisms formed by the geotextile bags filled with silt, silt is filled in the middle of the dike to form a core, and the horizontal plastic drainage plates are buried among the silt filled geotextile bags to form a horizontal drainage channel; during construction, the silt in a borrowing area is borrowed and filled to the core by a hydraulic fill process, and the silt is taken from the core to fill the geotextile bags to form the bagged silt prisms; after the silt is filled to the core, the precipitation wells and low-energy-level dynamic consolidation are adopted, the drainage consolidation of the silt filled core is quickened, and the compactness and the bearing capacity of the core are improved. The method is suitable for causeway, cofferdam, revetment, approach bank, breakwater, seawall, embankment construction.

Description

technical field [0001] The invention relates to a project of using silt to fill geotextile bags to build embankments to form embankments. Background technique [0002] At present, in the professional fields of ports, water conservancy, rock and soil, municipal administration, and highways, in the completed and ongoing embankment projects of geotextile filling bags to form dams, the current regulations require that sandy soil should be used as filling materials, and particles with a particle size greater than 0.075mm The content should be greater than 50%, which is relatively easy to achieve in areas with rich sand sources and has good application value. However, in areas where sandy soil is scarce and silt resources are abundant, due to the finer silt particles, poor drainage and soil retention, and slow consolidation of dam soil, there are currently few domestic embankments that use silt to fill geotextile bags. success case.

Problems solved by technology

[0003] The problem to be solved in the present invention is to develop a method of filling geotextile bags with silt instead of sandy soil to build embankments under the condition of lack of sandy soil and abundant silt resources, so as to solve the problem of slow drainage and consolidation of silt and uneven foundation bearing capacity. low problem
