The invention discloses an occlusive pipe curtain for a bored tunnel in a water-rich stratum and a construction method of the occlusive pipe curtain. The occlusive pipe curtain for the bored tunnel in the water-rich stratum comprises an occlusive pipe curtain body which is horizontally arranged along a tunnel excavation contour line. The occlusive pipe curtain body comprises clay-cement occlusive piles and concrete filled steel tube occlusive piles, wherein every two adjacent clay-cement occlusive piles are spaced from each other by a jump hole, and each concrete filled steel tube occlusive piles is arranged between the corresponding adjacent clay-cement occlusive piles. The invention further discloses the construction method of the occlusive pipe curtain for the bored tunnel in the water-rich stratum. The construction method comprises the following steps that the clay-cement occlusive piles are horizontally constructed along the tunnel excavation contour line; the concrete filled steel tube occlusive piles are constructed between the adjacent clay-cement occlusive piles; and a tunnel section is excavated step by step, and a steel tunnel body supporting frame is erected. According to the occlusive pipe curtain for the bored tunnel in the water-rich stratum and the construction method of the occlusive pipe curtain, a box type waterproof curtain body is formed through the occlusive pipe curtain body arranged outside the tunnel excavation contour line and a grout-preventing wall on the side wall of a transverse construction channel jointly, so that the waterproof effect of the tunnel excavation section is achieved; a supporting system is formed by the occlusive pipe curtain body and the steel tunnel body supporting frame jointly, and the technical effect of effectively controlling the deformation of the stratum can be achieved due to the fact the supporting and bearing capacity of the supporting system is high .
