| titleOfInvention | A kind of rotary digging stake pile-end post-grouting method |
| abstract | The present invention relates to a kind of rotary digging stake pile-end post-grouting methods.Post-grouting method, comprising the following steps: 1), madjack pipe prepares: with metal tube in lower end drilling processing slurry outlet, axially upper spacing is 40~60mm to adjacent two rows slurry outlets in pipe, and along the oblique arrangement that is staggered of pipe circumferential surface spiral shape；Iron filings in pipe are cleaned out after drilling, pulp aperture rubber skin is wrapped up and tied up, and rubber skin width is 50~80cm, and mud jacking infratubal port uses the steel plate slightly larger than pipe outside diameter to close；2), madjack pipe is fixed on steel reinforcement cage, and a stake side pressure grouting pipe and a pile base grouting pipe are at least set, steel reinforcement cage 30cm or more is stretched out in pile base grouting pipe lower end, and the main reinforcement spot welding of madjack pipe and steel reinforcement cage is simultaneously bound close；Then madjack pipe is transferred in stake holes with steel reinforcement cage；3) pile concrete, is poured.The present invention has stronger Popularizing of A, convenient for being widely popularized universal use. |
