Anti-settling structure around a road inspection well

Abstract

The utility model provides a kind of anti-settling structure of road inspection well periphery, it is related to municipal road facility technical field, and it includes: well edge support ring, the well edge support ring is circular ring structure, the longitudinal section of well edge support ring is in the form of U structure, support ring cover is covered above the well edge support ring, cement layer is equipped above the support ring cover, pitch layer is laid above the cement layer, the anti-settling structure of the utility model is added to the lower part around road inspection well, the well perimeter of road inspection well is strengthened to support, improve well perimeter ground strength, reduce the irregular pressure caused to well perimeter ground by stress concentration and lead to well perimeter subsidence, enhance the support intensity to well perimeter, solve the problem that the backfilling soil of road inspection well perimeter becomes loose or loss due to construction or seepage, forms weak area, when vehicle repeatedly rolls, soft soil subsides faster than hard wellbore, lead to road surface to be concave with well lid as center, and intensify with time elapses, form vicious cycle.
