Application and Discussion of Pressure Grouting Technology in Bored Piles

Abstract:

Bored Pile with pile-end pressure grouting technology has been widely used in high-rise buildings and large public buildings in Chinas Inner Mongolia region. Due to this bored pile take a osmosis, filled, replacement, consolidation and consolidation effect, it could have a special role on eliminating the dregs at the pile bottom and the holes hidden trouble between the pile soil and it also enhance the strength of the pile body, increasing the binding power of pile and the soil between the piles. With the result of that, the supporting capacity has a significantly improved and this technology has become the advanced scientific method of reducing the settlement of the pile foundation. By using a high-rise building projects pile example that takes bored piles with pile-end pressure grouting and static loading test, observations and determine the settlement value of the single vertical design capacity analysis methods, it shows that the pile-end pressure grouting bored piles, the layer of sand mixed capacity has been significantly improved.
