Definitions
- the cushion can be employed when placing either a manhole or valve-box covers that are made of iron, steel or plastic and consists of two parts (a frame and a cover/lid) and are commonly referred to as service covers.
- Such covers form part of a chamber used for access to underground pipe work and are normally constructed in roadways. They often develop structural faults as a result of vibration caused by heavy road vehicles, the visible sign of which is usually a sunken cover, resulting in an uneven and dangerous road surface.
- the Cover Bearing Cushion System consists of a rubber cushion that is bonded to a steel plate which is placed underneath the service cover frame in order to absorb any harmful vibration caused by road vehicles passing overhead. By absorbing such vibration the cushion prevents structural damage being caused to the chamber walls or foundations thereby ensuring that the cover remains at its intended level in relation to the road.

Abstract
A Cover Bearing Cushion comprises of a steel plate with a rubber or similar shock
absorbing materials, with load bearing properties capable of accepting vibrations from
road vehicles passing overhead. A recess runs the entire length of the of the bonded
rubber strip, this is to ensure majority vibrations is attracted to the centre of the
cushion, thereby affording greater edge protection
Description
- The cushion can be employed when placing either a manhole or valve-box covers that are made of iron, steel or plastic and consists of two parts (a frame and a cover/lid) and are commonly referred to as service covers.
- Such covers form part of a chamber used for access to underground pipe work and are normally constructed in roadways. They often develop structural faults as a result of vibration caused by heavy road vehicles, the visible sign of which is usually a sunken cover, resulting in an uneven and dangerous road surface.
- Remedial work to correct any fault is costly and causes inconvenience to road users since any repairs may call for the temporary closure of a carriageway.
- The Cover Bearing Cushion System consists of a rubber cushion that is bonded to a steel plate which is placed underneath the service cover frame in order to absorb any harmful vibration caused by road vehicles passing overhead. By absorbing such vibration the cushion prevents structural damage being caused to the chamber walls or foundations thereby ensuring that the cover remains at its intended level in relation to the road.
- A specific embodiment of the invention will now be described by way of an example with reference to the accompanying drawings: -
- Figure 1. This shows a plan view of the cushion.
- Figure 2. This shows a side view of the cushion (1) and the position of the steel plate (2).
- Figure 3. This show sectional view A-A, as indicated if figure 1, and details the recess (3) that runs the entire length of the cushion. The purpose of the recess is to ensure that the majority of movement is attracted to the centre of the cushion thereby affording greater edge protection.
- Figure 4. This sectional drawing shows the cushion system in situ and consists of the following details - (4) Service Cover, (5) Roadway, (6) Service Cover Frame, (7) Cover Bearing Cushion System, (8) Chamber Wall.
Claims (3)
- A beating cushion that is bonded to a steel plate which is placed underneath drainage manhole service cover frames in order to absorb any harmful vibration caused by road vehicles passing overhead.
- A cushion as claimed in Claim 1 that is placed underneath a valve-box cover to absorb any harmful vibration caused by road vehicles passing overhead.
- A cushion as claimed in Claim 1 that is placed underneath a cable service-box cover to absorb any harmful vibration caused by road vehicles passing overhead
