Matters needing attention in treating soft soil foundation by drainage consolidation method

1.Drainage consolidation method is applicable to soft soil with thickness greater than 5m, but soft soil with sensitivity of more than 5 is not suitable.
2.The preloading time of drainage consolidation method should be guaranteed for more than 6 months.
3.The construction section of bridge head should be pre compressed before excavation of pile foundations and caps, so as to avoid the displacement of pile foundations and caps due to preloading.
4.In order to improve the overall stability of the embankment and the drainage performance of the cushion, geosynthetics can be installed in the horizontal drainage cushion.
5.The adjacent sections of the structure should be combined with the plastic drain board combined with overloading preloading, and the height of overloading is generally 30% to 50%, with high filling and tight filling period, the vacuum combined loading preloading can be used.

PARFECT soil stabilization equipment can transfer the soil binder through the air compressor to the mixing head which is mounted on the excavator, and mix with the soil to improve the strength of the foundation.

Treatment of soft soil foundation by high pressure injection method

图片
The method is to use a drilling machine to inject a nozzle pipe into the soil layer. The slurry or water is ejected from the nozzle at high pressure to form a jet stream to destroy the soil layer. When the energy of high speed jet fluctuation was shaped, the dynamic pressure is greater than the strength of soil structure, soil particles stripping down from soil, part of the particles spread out with slurry or water, other soil particles mixed with slurry under the jet impact force, centrifugal force and gravity force, re arrange regularly according to the size of a certain percentage of soil and quality. After the slurry solidified, forming a solidified body in soil, can improve the bearing capacity of the foundation, reduce the settlement, can also improve the effecf of supporting and anti-seepage. It is suitable for foundations of silt, cohesive soil, loess, sandy soil, artificial fill and crushed stone soil. PARFECT soil stabilization equipment can transfer the soil binder t

Geotextile reinforcement method of soft soil foundation treatment

In order to improve the bearing capacity of foundation, reduce the settlement and increase the stability of foundation, the artificial composite soil can be subjected to tensile, compressive, shear or bending action. It is suitable for various soft foundations. The basic principle of reinforcement is to transfer the tensile stress in the soil to the reinforced body through the friction action between the soil and the reinforcement, and the reinforcement is subjected to pulling force. The stress and shear stress of the soil between the reinforcing bars can make the reinforcement and the soil in the reinforced soil play their respective roles. The common geotextiles include geogrids, geotextiles and geocell. In addition to geosynthetics and geogrids, geocell can delay or cut the sliding surface of foundation failure, so that the bearing capacity of foundation is improved. Moreover, geocell can in the soil compartment given three-dimensional constraint, the soil particles become a geocell

Traditional sludge disposal methods

图片
Most of the mud from the small ponds or river in the countryside is directly backfilled to farmlands nearby, which is the most common sludge disposal method used in rural areas in the past few decades. This sludge disposal method has many disadvantages: Some of the sludge has heavy metal pollution, or contains a lot of household waste and construction waste, and farmers refuse to accept it; After returning to the fields, it takes several years to dry. After airing, it needs second treatments. During this period, the fields can not be planted, and the government should pay farmers 1 ~ 2 years’ compensation fees in the form of rent. Cleaned out sludge of coastal rivers, lakes, ponds, and a considerable part of ithave been dumped at sea. In this way, the freight is expensive and tidal, and mud may be washed back inland. In Ningbo, China, the sludge being cleared will be dumped into sea which cost 176 RMB per cubic meter. The river silt in urban areas are often polluted, will usually
