| description | The invention provides a freezing and thawing protection method and structure for a ditch. The method comprises the following steps that a plurality of ditch bottom fixing plates are fixed to the bottom of the ditch in a mutually inserted mode; the two sides of each ditch bottom fixing plate are each provided with a side wall movable plate abutting against the side wall of the ditch, and the side wall movable plates are rotatably connected to the two sides of the ditch bottom fixing plates; and a waterproof film is laid on the prefabricated concrete member composed of the trench bottom fixed plate and the side wall movable plate. According to the freeze-thaw protection structure and method, a deformable prefabricated concrete member is provided, the ditch bottom fixing plate at the bottom is used for being fixed to the bottom of the ditch so that it can be guaranteed that the overall trend of the ditch cannot be deformed, and the side wall movable plates on the two sides can be fixed to the bottom of the ditc |
