The invention provides a water collection and drainage and anti-liquidation slide-resistant pile and a construction method thereof and belongs to the technical field of slope supporting. The water collection and drainage and anti-liquidation slide-resistant pile is composed of a concrete-filled steel pipe pile, a reinforced concrete foundation pier, an annular water collection iron box, a previousconcrete tubular pile, a reverse filter screen, a water pumping pipe and a handheld water pump. The annular water collection iron box is arranged outside the concrete-filled steel pipe pile in a sleeving mode and arranged on the reinforced concrete foundation pier. The previous concrete tubular pile is arranged on the annular water collection iron box through pouring. The previous concrete tubular pile is sleeved with the reverse filter screen. The water pumping pipe is pre-buried in the previous concrete tubular pile and inserted into the bottom of the annular water collection iron box. Thehandheld water pump is mounted on the top of a pile body and is connected with the water pumping pipe. The slide-resistant pile can be prefabricated or fabricated in a cast-in-place mode and is largein rigidity, strong in shear capacity and high in bearing capacity. According to the structure and an adopted material of the pile, infiltrating surface water can be collected and drained; the adverseinfluence of rising of the underwater level on the slope stability is mitigated. A soil body on the periphery of the pile can be protected against liquefaction under the condition of an earthquake. The water collection and drainage and anti-liquidation slide-resistant pile is easy and convenient to construct and low in construction cost.
