| description | The invention provides a top-down system of a pipe-jacking working well wall in a soft soil area and a construction method and an application thereof. The top-down system of the pipe-jacking working well wall in the soft soil area comprises an annular guide wall, a waterproof curtain, a bottom rigid-flexible combined pile, a connecting ring beam, a well wall reinforcement cage and an inner wall formwork, wherein the annular guide wall is arranged at the periphery of a pipe-jacking working well. The construction method comprises the following steps of (1) constructing the annular guide wall; (2) constructing the waterproof curtain; (3) constructing the bottom rigid-flexible composite pile (inserting H-shaped steel); (4) constructing the connecting ring beam; (5) digging soil in the core ofthe well; (6) binding and welding the well wall cage; (7) hanging the inner wall formwork; (8) pouring well wall concrete, removing the inner wall formwork after the concrete is hardened to a certaindegree, so that the constr |
