Pressure-resistant manhole cover for repair and method of installing same

Abstract

The invention discloses a pressure-resistant manhole cover for repair and a method for installing it. The outer wall of the ring body and the inner wall of the ring body are respectively provided with a first wrapping edge and a second wrapping edge, and the outer wall of the cover body is The third edge is provided, and the width of the ring body is at least 16cm; the method for installing the pressure-resistant manhole cover includes the following steps in turn: cutting and opening a pit with the same shape as the outer edge of the ring body on the road surface; Expand a hoisting width outside, the hoisting width is less than 6cm; hoist the cover body on the ring body, and cover it on the through hole of the ring body. The invention has the beneficial effects of: improving construction efficiency; no repair traces and obvious joints between the ring body and the road surface; the area of ​​the ring body and the cover body is enlarged, with high strength and compression resistance; the surface of the well ring covers the edge of the well cover and the cut , The repair material between the edges of the pit is beautiful, the well ring protects the repair material, it is not easy to be damaged again after the vehicle is rolled, it comes with anti-fall hooks, anti-fall nets, and it is safer to 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 the same. Background technique [0002] At present, the existing design principle of manhole cover is that the manhole cover is pressed on the well circle, the frame of the well circle is very narrow, the area of ​​the well circle is very small, and the road pressure is transmitted to a small area, which is easy to cause road damage. The original well circle is pressed on the asphalt Above the road foundation and below the asphalt surface, the asphalt covers the well circle, and the well circle is not visible on the surface. After the original manhole cover is paved with asphalt at the bottom layer, the manhole cover needs to be lifted, and then the surface layer asphalt is spread. The lifting process has destroyed the connection between the manhole cover and the underlying pavement, causing injury, and the vehicle walking directly ...

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
