Ice Skating in Yard?

My back yard is completely paved in tiles that are pitched to a center water drain. Because of the rain, snow and cold weather these past several weeks the water has left what looks like a large ice skating pond. When the weather warmed up a few days ago, I melted the ice covering the drain with boiling hot water, yet the underground pipe must be frozen because no water would penetrate. Now it is completely covered once again. I’m worried the underground pipe might bust from being frozen. Any suggestions?
