Question:

What is soft ground treatment?

What is soft ground treatment?

Answer:

. drainage consolidation method is the natural foundation, or in the ground setting sand (sand wick or plastic drainage belt) and vertical drainage body, and then use the weight of the building itself gradually grading loading; or in the building on the site before the first load preloading, the discharge pore water in the soil gradually consolidation at the same time, ground settlement, strength gradually improved.
1., when the silt layer is thicker, it is difficult to carry out the deep treatment in large area, and the pile driving method can be used to reinforce the soil.2. when the silt layer thickness is relatively thin, but also can be used for filling soil and sandy loam, soil, sand, cement and the caisson foundation and other measures were given for sand foundation treatment, is not conducive to the prevention of seepage, and the engineering cost is higher, the general should be local, in exchange for the silt is appropriate.3. grouting is the use of air pressure, hydraulic or electrochemical principles, will be able to solidify some of the grout into the foundation medium or building and the gap of the foundation. The essence of grouting is to inject some solidified grout into natural and man-made cracks or pores by means of air pressure, hydraulic pressure or electrochemistry, so as to improve the physical and mechanical properties of various mediums.
Before the building if the foundation is not strong enough to prevent the building foundation caused by sinking ripping buildings instability accident, need to soft foundation treatment, the settlement became strong enough to improve the soft foundation consolidation degree and stability to the design requirements, this process is called soft foundation treatment, also called soft foundation treatment.
