AI Technical Summary

Technical Problem

Existing manhole cover systems are prone to damage under heavy loads, leading to manhole cover settlement, displacement, and vibration, which affects passenger comfort and driving safety. Furthermore, the connection between the manhole ring and the road surface is prone to breakage due to friction.

Method used

The manhole cover body and manhole ring body are located above the rubber bushing. The rubber bushing reduces the friction between the manhole ring and the road surface. The height of the manhole cover is adjusted by adjusting screws, limit screws and support springs. Combined with the top support rod and support pulley structure, the manhole cover is supported to prevent settlement and breakage.

Benefits of technology

It effectively prevents manhole cover settlement and manhole ring breakage, reduces maintenance costs, improves passenger comfort and driving safety, and is easy to operate and maintain.

Abstract

本发明公开了一种具有高度调节功能的防沉降井盖及其方法,属于防沉降井盖技术领域。一种具有高度调节功能的防沉降井盖及其方法,包括井道主体、井圈主体和井盖主体,还包括顶撑回形杆,其设置于井道主体的内部,所述井道主体包括下井道和承接井道。为解决荷载会直接作用在井圈和井盖上,但井盖在长期荷载作用下,不断发生弹性变形,使井周沥青在井盖边框反复作用下变形至极限造成疲劳破坏,断裂破损的问题,当井盖主体和井圈主体受到来自车辆的冲击时,作用力会通过井盖和井圈向下传递给橡胶衬套,利用橡胶衬套来降低井圈与柏油路面之间的摩擦,从而避免井圈与路面之间的连接处在反复作用下出现断裂破损的情况。
