This invention relates to the field of pipeline seepage prevention technology, specifically to a pipeline seepage prevention deformation control support device based on soft soil foundation. The device is installed at the connection point of two adjacent pipelines. The device includes a bearing ring, a support member, and at least n sets of limiting members. Bearing rings are connected to the outer walls of both pipelines near the connection point. Each set of limiting members includes two bearing plates, arranged in an inverted V-shape with alternating front-to-back arrangements. Each bearing plate has a recessed groove containing a friction plate that slides back and forth. When the lower left side of the n bearing plates on the left side of the n sets of limiting members is far from the lower right side of the n bearing plates on the right side, the two friction plates in the same set make relative pressure contact. The support member supports the limiting members. This invention solves the problem that when a support device supports a pipeline, it easily shifts downwards with the settlement of the soft soil foundation, leading to deformation and leakage at the weak connection point of the supported pipeline.
