You could line the inside of the pool with sections of polycarbonate greenhouse panels (can sometimes be found at Lowes). They could be cut to the height of the pond, screwed together with stainless bolts, or perhaps glued with silicone (if it will stick to poly), the top clipped to the pond and the bottom edge sunk into gravel or sand or rocks. It should protect the liner, it is very tough stuff.
