Pressure-resistant well lid for repair and method for mounting pressure-resistant well lid

Abstract

The invention discloses a pressure-resistant well lid for repair and a method for mounting the pressure-resistant well lid. The outer sidewall of a ring body is provided with a first covered edge, and the inner sidewall of the ring body is provided with a second covered edge. The outer sidewall of a lid body is provided with a third covered edge. The width of the ring body is at least 16 cm. The method for mounting the pressure-resistant well lid sequentially comprises the following steps that firstly, a pit with the same shape as the outer edge of the ring body is cut in the road surface through a special device; secondly, the edge of the pit is evenly expanded outwards by a hoisting width, and the hoisting width is less than 6 cm; and thirdly, the lid body is hoisted onto the ring body and arranged on a through hole of the ring body in a covering mode. The pressure-resistant well lid for repair and the method for mounting the pressure-resistant well lid have the beneficial effects that the construction efficiency is improved; no repair mark and no obvious joint exist between the ring body and the road surface; the area of the ring body and the area of the lid body are expanded, and the well lid is high in strength and resistant to pressure; the surface of a well ring covers repair materials between the edge of the well lid and the edge of the cut pit, the appearance is attractive, the well ring protects the repair materials, and the well lid is not prone to secondary damage after being crushed by vehicles; the well lid is provided with anti-falling hooks and an anti-falling net, thereby being safer in use.

Description

technical field [0001] The invention relates to a well cover, in particular to a pressure-resistant well cover for repair and a method for installing it. Background technique [0002] At present, the existing manhole cover design principle is that the manhole cover is pressed on the well circle, the well circle frame is very narrow, the stress area of ​​the well circle is very small, the pressure of the road surface is transmitted to a small area, and it is easy to cause road damage. The original well circle is pressed on the asphalt On the road foundation, under the asphalt surface layer, the asphalt covers the well circle, and the well circle cannot be seen on the surface. The original manhole cover needs to be lifted after the bottom asphalt is paved, and then the surface layer of asphalt is paved. The lifting process has destroyed the connection between the manhole cover and the underlying road surface, causing damage. Vehicle walking directly causes the road surface aro...

Problems solved by technology

[0002] At present, the existing manhole cover design principle is that the manhole cover is pressed on the well circle, the well circle frame is very narrow, the stress area of ​​the well circle is very small, the pressure of the road surface is transmitted to a small area, and it is easy to cause road damage. The original well circle is pressed on the asphalt On the road foundation, under the asphalt surface layer, the asphalt covers the well circle, and the well circle cannot be seen on the surface

After the original manhole cover is paved with asphalt at the bottom, it is necessary to lift the manhole cover, and then pave the surface layer of asphalt. The lifting process has destroyed the connection between the manhole cover and the underlying road surface, causing damage. Vehicle walking directly causes the road surface around the manhole cover to collapse and damage
