According to a diagonal metric tensor, a set of exact gravitational soliton solutions of Einstein's equations in vacuum is obtained, which discribe two solitons propagating with constant velocity in opposite directions. After collision, they will continue to propagate without changing their original shape. Firally, the singularity and energy density of these solutions are also discussed.
