Pile grouting can significantly improve the bearing capacity of bored piles. O-CELL test is widely used to test the carrying capacity of piles in foreign countries. Compared with the traditional top-loading method, O-CELL test has the advantages of large loading capacity, small size and low cost. Describes the pile grouting process and the effect of the Puxi West Bridge bored pile bottom pile, and the O-CELL method for static load test
