Self-water-replenishing road concrete construction system

The invention belongs to the technical field of concrete, particularly relates to a self-water-replenishing road concrete construction system, and provides the following scheme aiming at the problems that in the prior art, a self-water-replenishing road concrete construction system cannot achieve the effect of automatically circulating and automatically replenishing water. Meanwhile, a device cannot be fixed when water is replenished again. The device comprises a base, the base is of a hollow structure, a shell is fixedly installed at the top of the base, a water storage pipe is fixedly connected into the shell, a buoyancy plate is slidably connected into the water storage pipe, two pushing plates are symmetrically and fixedly connected to the bottom of the buoyancy plate, and two supporting rods are symmetrically and fixedly connected to the bottom of the base; the bottom of each supporting rod is rotationally connected with a rolling wheel, one side of each rolling wheel is fixedly connected with a gear, th
