FIELD: construction.
SUBSTANCE: invention can be used in the construction of culverts under embankments of highways in the conditions of the northern construction-climatic zone in the presence of ice and/or strong transport. The culvert includes a concrete pipe, inlet and outlet heads with flaps, laid on a bulk permeable layer. The structure is equipped with a container with a heat-insulated bottom located at the entrance head, filled with saline solution and installed close to the end walls of the entrance head with penetration into the ground, while the upper part of the container at the pipe level has through holes.
EFFECT: simplifying the design and increasing operational reliability.
