Post Pressuregrouting Technique for the Bored Pile Completed with the Borehole Wall Protected by Mud and the Estimating Method of Vertical Bearing Capacity of Single Pile

Abstract:

By giving some construction cases of pilebottom post pressuregrouting conducted in recent years in China, introduction is made on the development of post pressuregrouting pile. Conditions under the pile and relevant technical references are analyzed, estimating methods of vertical bearing capacity of single pile are concluded. And these can be taken as basis for the preliminary design of a pile distribution plan.
