QUESTION
Is there any alternative to concrete rings in open well ?

We have an open well in our agriculture land but the soil from the sides are falling frequently into the well. The soil is preventing the water coming to the well from its sides. We want to fix this permanently but the option we see is concrete rings, but by considering the size of our well it looks a bit expensive option. Please suggest if there is an alternative to this.
