| Abstract: | There were many bored piles with large diameter of 3.0 m and 2.5 m in the substructure of piers in the main bridge located in the Mulan River bridge of the avenue of Chenggang. After pouring concrete we detected that some bored piles were so deficient that the quality of the bridge was seriously affected. We used the method of boring hole to pour grout to handle the problem. We found the piles with some defects accorded with the design demand through this process. |
