Embodiment Construction

[0025] Such as figure 1 , figure 2 , image 3 As shown, the anti-settling cable well cover includes a frame body 1 and a cover body 2, the frame body 1 includes a body 3 matched with the cover body 2, and a section of flange 4 connected to the pavement structure layer, the body 3 It includes a mounting seat 31 for the well cover installation and a socket part 32 extending into the well body. The socket part 32 is closely matched with the inner wall of the well body. The flange 4 includes a horizontal section parallel to the road structure layer. A pressure-bearing section 41 and an inclined section 42 extending into the pavement structure layer. The body 3 is provided with a rubber strip 5 that reduces the vibration between the frame body 1 and the cover body 2. The cover body 2 is provided with a The limit projection 20 of the body 3, the cover and the frame are all made of ductile iron, and when in use, they are inserted into the road structure layer through the flange, t...

Abstract

The invention discloses an anti-settling cable well lid. The anti-settling cable well lid comprises a frame body and a cover body, wherein the frame body comprises a body and a flange plate, and the body comprises a mounting base and a bearing and inserting part; the flange plate comprises a horizontal pressure-bearing section and an inclined section, and a rubber strip for reducing vibration between the frame body and the cover body is arranged on the body. The anti-settling cable well lid has the advantages that the frame body is arranged into the structure of the body and the flange plate,a whole body is formed by the body and a pavement structure layer through the flange plate, the whole well lid is enabled to be a complete part of the pavement, load can be directly dispersed to the pavement structure layer, the asphalt pavement around the well lid is protected, and the settling is prevented; and the mounting base for installing the well lid and the bearing and inserting part extending into a well body are arranged through the body, the load pressure of the upper part is dispersed to the structural layer of the pavement through the flange plate, so that the load borne by the well body is enabled to be reduced by 80% or above, so that the possibility that a well mouth is damaged or the well lid sank is reduced, the flange plate plays a good role in protecting the pavement surface around the well lid, and the service life of the well lid is prolonged.

Description

technical field [0001] The invention relates to an anti-subsidence cable well cover. Background technique [0002] At present, in order to promote urbanization, since the continuous reconstruction of old urban areas, the widening of roads, and the distribution of a large number of manhole cover facilities in urban roads and sidewalks, traditional circular manhole covers have thin walls and external hinges. When passing through quickly, there is not only vertical downward pressure on the inspection shaft, but also horizontal impact. Under the action of continuous impact force, the position of the well frame moves, causing the surrounding asphalt layer to crack, the area of ​​the manhole cover frame to sink or protrude, and the contact surface of the manhole cover frame is not smooth. , The traditional manhole cover uses ordinary rubber strips, and the fixation is also glued or screwed on the steel structure, so the rubber strips are easy to fall off and aging, and ultimately...
