How do you stop a small wooden porch from caving in? - small wooden dingy boat designs

I have a tree house for my children. The small porch outside is soft and begins to fall. The beam is split into two parts. I want to save this tree house, but I have little money to work. I have also tried to climb with a 4x4, but the ground is too soft and falls to the floor board when it hit me.
