Back wall for pipe jacking method connection channel construction

The invention discloses a back wall for pipe jacking method connection channel construction. The back wall comprises a back wall body. The front face of the back wall body is a straight face, and the back face of the back wall body is an arc-shaped face. The back wall body is formed by welding metal, and a circular hole is formed in the middle of the back wall body; and the arc-shaped surface of the back wall body is fixedly connected with a rubber pad. The steel prefabricated back wall is adopted, the strength is high, the construction time is shortened, the steel prefabricated back wall can be repeatedly used, economic benefits are improved, the rubber pad is arranged on the arc-shaped face of the back wall body, so that uneven stress caused by uneven tunnel surface is eliminated, the back wall can be stressed more evenly, shaking of the back wall is avoided, and the service life of the back wall is prolonged. And the use safety is improved. 本发明公开了一种顶管法联络通道施工用后背墙，包括后背墙本体；所述后背墙本体的正面为直面，所述后背墙本体的背面为弧形面；所述后背墙本体
