Preferably, the shape of the earth work bag is a rectangular flat shape, and the weight of the earth work bag after being filled with soil is between 200 and 600 kilograms.
Preferably, the geotextile laid on the surface of the soft soil foundation is a layer laid after the surface of the soft soil foundation is drained and leveled, and the layer is connected into a whole geotextile.
Preferably, the geotextile is paved with a plurality of geotextile bags, and the number of the geotextile bags is 4 to 6.
Preferably, the geotextile is provided with geotextile bags, and the long edge of each geotextile bag is perpendicular to the road direction.
Preferably, the geotextile bags are laid on the geotextile, and the gap between each layer of the geotextile bags and the periphery of the geotextile bags is about 10 cm.
Preferably, the geotextile bags are laid on the geotextile, and from the second layer, each geotextile bag is pressed at the cross-shaped joint of the next four geotextile bags, so that the staggered lamination effect is formed.
Preferably, the geotextile is paved with the geotextile, and after each layer of paved geotextile bags are compacted by a road roller, gaps among the geotextile bags are filled with loose soil.
The invention has the beneficial effects that: the technology for treating the soft soil foundation of the road by the geotextile bags is provided, aims to provide a new technology for treating the soft soil foundation in road construction, replaces the conventional method for replacing and filling the soft soil foundation of the road, is convenient and simple to construct, has social benefits of replacing stone with soil in terms of environmental protection, and can greatly reduce the road construction cost in terms of economic benefits.
