The post-pressure grouting to the pile tip and pile lateral technology of cast-in-place bored pile and its application

With the typical project example,this paper introduces the principle,methodology and application of post-pressure grouting technique to the pile tip and pile lateral of reinforced concrete cast-in-place bored pile.The technology is applied by post-pressure grouting to the pile tip and pile lateral on condition that the pile has certain intensity,so as to increase the bearing capacity of single pile and pile group.Static loading test has proven that the bearing capacity has been increased by more that 30%.
