| Abstract: |
| Combining with the construction example of high-pressure jet grouting wall for foundation of drainage gate station of Fuchunjiang dry embankment reinforcement project, under different geological conditions including large-particle sand and pebble layer and silty clay layer, through comparison and selection of construction technology and technical parameters of three-pipe method and two-pipe method, quality control of hole spacing, sequencing and leakage grout treatment during construction process, and quality inspection of high-pressure jet grouting wall are carried out. By means of excavation inspection, borehole coring method, hydrostatic head pressure test and heavy dynamic sounding test, and through comparative analysis of test indexes, the results show that the wall quality of silty clay layer or silty clay layer is better than that of sand and pebble layer with large particle size. |
