anti-subsidence manhole cover

Abstract

The invention relates to the field of road engineering, in particular to an anti-settling manhole cover, comprising a cover plate and a well seat, the well seat is located on the top of a masonry wellbore, the cover plate is located in the well seat, and the well seat comprises a bottom plate, a face plate and an annular vertical plate and a number of reinforcing plates, the width of the panel is smaller than the width of the bottom plate, the top of the annular vertical plate is integrally formed with the panel, the bottom of the annular vertical plate is integrally formed with the bottom plate, the reinforcing plate is vertical and the top end is fixedly connected to the panel, and the bottom end and the bottom plate are integrally formed. Fixed connection, side ends are fixedly connected with the annular vertical plate, all reinforcing plates are evenly distributed around the annular vertical plate, and the upper surface of the panel is flush with the road surface. The invention utilizes the blocking limit of the reinforcing plate, so that the pavement material between the two adjacent reinforcing plates cannot escape along the direction perpendicular to the driving direction, so as to avoid the road surface around the well seat from being crushed by the vehicle; the drawer lock is used to lock the cover plate, and only the Only use a special key and special tools such as a spudger to open the cover, which reduces the probability of the cover being stolen.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to an anti-settling well cover. Background technique [0002] The current municipal engineering is vigorously promoting the application of five-proof manhole covers. The five-proofs are anti-settling, anti-noise, anti-theft, and prevention of accidental jumping and closing. In the end, it will not play a real "five defenses" role. [0003] The currently used well cover structure is the well base buried under the road surface and the well cover set on the well base. For the road with heavy load, the road around the well base is easily crushed by the cart, resulting in uneven road surface and potential safety hazards. . Urban pavements are generally maintained once every 3-5 years. On roads with heavy loads, inspection manhole covers will be crushed and damaged within a few months of use, and need to be replaced and repaired.

[0003] The manhole cover structure currently used is the well base buried under the road surface and the well cover set on the well base. For the road with heavy load, the road around the well base is easily crushed by the cart, resulting in uneven road surface and potential safety hazards.

Urban pavements are generally maintained once every 3-5 years, and on roads with heavy loads, inspection manhole covers will be crushed and damaged within a few months of use, and need to be replaced and repaired. This makes the pavement maintenance and manhole cover maintenance periods inconsistent. Road construction personnel cannot maintain the road surface in time, and the workload increases
