The application of three-axis cement soil mixing piles in SMW construction method walls has been quite mature.Its excellent verticality and controllable overlap width between piles make it a very effective underground structure construction method.However,applying it as a waterproof curtain in deep,medium dense to dense sand layers is a relatively novel attempt.The engineering test results show that using three-axis mixing piles for waterproofing in deep sand layers near the sea area is a relatively economical and feasible method.
