High-pressure-resistant road surface elastic well lid

The invention discloses a high-pressure-resistant road surface elastic well lid. The well lid comprises a well lid body; bases are installed on two sides of the bottom of the well lid body; limiting columns are installed in the centers of the bottoms of the bases; the bottom ends of the limiting columns pass through holes to be connected with limiting plates; the through holes are formed in two sides of the upper surface of an arch-shaped elastic piece; the tops of the limiting plates are installed on two sides of the bottom of the arch-shaped elastic piece; a wellhead is installed at the bottom of the arch-shaped elastic piece; and a buffer plate is arranged between the wellhead and the arch-shaped elastic piece. According to the elastic well lid, high-pressure-resistant elastic force iseffectively arranged on the well lid, durability reduction caused by abrasion of the well lid and severe abrasion of the wellhead in the later use process is prevented, the situation that the well lidis broken by excessively
