The invention discloses a matching device for curbstones and an electric power well, which is characterized by comprising curbstones and an electric power well. The curbstones are embedded at the periphery of the electric power well; the curbstones are in circular arc transition at one right-angle corner of the electric power well. The matching device has the beneficial effects that a technical scheme that the curbstones with arc corners are preset is adopted to efficiently avoid disadvantages of the curbstones meeting with one right-angle corner; the problem that a traditional curbstone is damaged easily at an acute-angle place of the electric power well, the problem of shortage of standardization of the electric power well and the like are solved radically; the construction difficulty that the traditional construction structure cannot satisfy engineering needs is solved; the technical scheme becomes an effective means for constructing an environment-friendly, energy-saving, efficient and green transformer substation, and the matching device has an important practical significance on construction and running as well as maintaining work of the current transformer substation; good economic and social benefits are also achieved.
