Abstract：Research purpose: This method of Curtain Grouting had the advantages of selection for construction equipment without limit of time and space, little flush fluid of grout-recycling in the hole and wastewater that are not particularly treated and no pollution to underwater and environment. And then the strengths of all kinds of strata soil treated by this method had a great increment, the permeability of which decreases greatly. And strata soil treated could protect borehole walls and cores. The problem, which was difficulty of forming boreholes in the piles construction of watery strata with high permeability and high confined water head, could be solved by application of curtain grouting and further discussed the application experience of this technology in southwest area of Yangtze River Bridge.
Research method: As the practical engineering of Yangtze River Bridge for example, this paper discussed the key points, construction technology and test method of water proof in situ.
Research result: The result of test in situ revealed that the permeability of all kinds of strata soil was about 10-5 cm/s in an average water pressured state, but maybe increases so that strata soil maybe hydrosplitted in the water pressure that was more than 0.3 MPa.
Research conclusion: The conclusion demonstrated that the curtain grouting technology could prevent water very well when holes were dug.
