Geotextile For Soft Soil Foundation

Geotextile For Soft Soil Foundation

Geotextiles play an extremely important role in anti-seepage solutions for soft and frozen soil. A large number of engineering tests have proved that geotextile is an important material for anti-seepage of soft soil and frozen soil.

The characteristics and hazards of soft soil foundation and high-cold frozen soil foundation:
       1. Characteristics: The characteristics of soft soil foundation and high-cold frozen soil foundation refer to the high natural water content, large void ratio, and compression of coastal seas, lakes and marshes, valleys, and river beaches.The base layer is composed of fine-grained soil with high resistance and low shear strength; it has high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, and disturbance The characteristics of high performance, poor water permeability, complex layered distribution of soil layers, and large differences in physical and mechanical properties between layers.


2. Harm: The main cause of the disease of the soil foundation and the high-cold frozen soil foundation is the high water content of the soil layer. Water is the main reason for the stability of the foundation. What kind of construction technology is used to control our load-bearing foundation layer during the construction process Always keep it at the ideal water content and keep it at the same water content forever. Stabilizing the foundation and maintaining the bearing capacity are the keys to ensuring the quality of the project.


Geotextile for soft soil foundation seepage prevention solutions:
      1. Foundation excavation: foundation excavation and backfilling crushed stone original soil, rolling and excavating drainage ditches on both sides of the foundation, backfilling spun yarn on the rolled foundation layer and laying a layer of non-woven geotextile on it;


2. Lay a geomembrane on the geotextile, and a layer of non-woven geotextile on the geomembrane. If the water content of the original soil is not very high during the construction of the original soil, the water content of the backfill foundation can be reduced by layered backfill and sprinkled with quicklime. When the backfill is rolled to a certain thickness, the geomembrane is wrapped and welded to form a permanent support layer that maintains the water bearing capacity.


Geotextile for soft soil foundation can wrap the entire roadbed for construction, and the side slope of the foundation can be backfilled with a planting soil layer. Permanently maintain the strength of the foundation to prevent settlement and deformation damage on the seepage prevention surface. If the water content is higher, it can be pre-buried in the foundation during backfilling
The perforated blind drainage pipe adopts segmented backfilling and rolling combined with vacuum depressurization to extract water from the backfilled soil. Keep the backfill foundation in a more ideal water content range and keep it sealed. The quicklime returns to heat after contacting the moisture in the frozen soil, and the heat can accelerate the thawing of the moisture in the frozen soil. The thawing of the moisture enables us to quickly heat


The moisture in the frozen soil is smoothly removed by rolling and squeezing and vacuum extraction construction technology to maintain the moisture content of the backfill foundation at an ideal position. Without moisture, the freeze-thaw and frost heave damage is reduced.
