Emergency Method to Handle Blockage Pipe and Fracture of Bored Pile |
| |
| Abstract: | In case,fracture of the cast in-situ pile occurs due to the blockage of vetical pipe in casting or due to the pipe pulling out,the method of embedding another vertical pipe should be used.And then,the pile is casted in-situ again or the bottom is cleaned with mud and a new pipe is embedded by 3 meters with fat motor.The methods can prevent pile from fracturing and ensure the quality of construction to relieve the loss of supplementary pile. |

| Keywords: | secondary pipe-embedding cleaning the bottom with fat mortar |
