Problems solved by technology

[0002] Due to the different particle composition and physical properties of the soil and the different thickness of the soil layer, especially for soft soil and other special soils, the filling soil of the existing road embankment is often difficult to control the settlement, and the settlement time is also long, because the stiffness between the soil The difference also produces uneven settlement, and it is also easy to cause the instability of the roadbed slope, and also cause cracks on the road surface due to the shrinkage and expansion of the soil.
At present, the commonly used method is to replace the soil or improve the soil. The construction period is long and the investment is large.

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] In the figure, the soil and rocks excavated on-site or nearby are put into geotechnical woven bags to form a geotechnical bag 1, which is stacked on the side of the subgrade base 2 for use; after the subgrade base 2 is sorted out according to the specifications, the subgrade base The geotechnical bags 1 filled on both sides are criss-crossed and stacked layer by layer to form the geotechnical bag subgrade 3 to the road surface 4; the gaps between the geotechnical bags 1 are filled with site soil or gravel; each layer of geotechnical bags is compacted mechanically or manually; the road surface 4 Laying of asphalt, concrete or gravel to specification; surface protection5.

[0015] In cold regions, the geotechnical bag 1 formed by filling the gravel in the geotextile bag can prevent the rise of underground capillary water, prevent...

Abstract

A soilbag roadbed and a method. The soilbag roadbed comprises soilbags, a roadbed substrate, a soilbag roadbed, a pavement and a surface protection. Soilbags are staggered vertically and horizontally and stacked up layer by layer from the roadbed substrate to be tightly combined with asphalt, concrete or broken stone paved on the pavement. The invention is simple, practical, thrift and economical and has substantial social and economic benefits.

Description

technical field [0001] The invention relates to a road subgrade and a method, in particular to a road geotechnical bag subgrade and a method. Background technique [0002] Due to the different particle composition and physical properties of the soil and the different thickness of the soil layer, especially for soft soil and other special soils, the filling soil of the existing road embankment is often difficult to control the settlement, and the settlement time is also long, because the stiffness between the soil The difference also produces uneven settlement, and it is also easy to cause the instability of the embankment slope, and also cause cracks on the road surface due to the shrinkage and expansion of the soil. At present, the commonly used method is to replace the soil or improve the soil. The construction period is long and the investment is relatively large. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and provides...
