Technical Field

[0001] The utility model relates to the technical field of seepage cutoff walls, in particular to a sheet pile seepage cutoff wall used for water conservancy. Background Art

[0002] Sheet pile cut-off wall, especially for water conservancy projects, is an important engineering technology, mainly used to strengthen embankments, reduce the escape point of the embankment infiltration line, and ensure the safety of the embankment. This technology is constructed by grooving (making holes) on the ground, using mud to solidify the wall in the foundation, digging slot holes or interlocking pile holes, and then backfilling with anti-seepage materials to build an underground continuous wall with anti-seepage performance. Among them, concrete cut-off wall is a commonly used type. During the construction of water conservancy projects, the construction of concrete cut-off walls can effectively avoid leakage problems in the embankment body and embankment foundation. This cut-off wall is formed by grooving on the ground and then filling it with concrete. Its advantage is that it can effectively prevent the penetration of water, thereby improving the stability and safety of water conservancy projects. Sheet pile cut-off wall technology plays an important role in water conservancy projects, and can effectively improve the anti-seepage performance of water conservancy projects and ensure their safe and stable operation.

At the same time, the connecting rod 14 in the fixing groove 8 is inserted into the connecting groove 13 on the fixing rod 7. The connection between the fixed wallboard 4 and the connecting wallboard 5 is more stable through the two-way insertion.

[0049] The anti-seepage plate 21 can block the connection between the wall panels and play an anti-seepage role. Injecting waterproof gel 24 into the anti-seepage groove 19 can make the connection between the anti-seepage plate 21 and the cut-off wall body 3 more stable and fill the connection at the same time, thereby enhancing the anti-seepage effect. The setting of the anti-seepage corner 20 can guide the gap at the connection to the anti-seepage corner 20.
