Problems solved by technology

When it is necessary to open the manhole cover, the raised manhole cover is turned backwards, and the angle of the manhole cover turned backwards is limited by the hinge of the well seat. The raised manhole cover forms an obstacle on the road during construction, and various traffic accidents are prone to occur
Therefore, in the various constructions that need to open the pipeline manhole cover on the road, the construction party must carry the relevant traffic warning signs and place them on the road by a special person, which not only increases the construction cost, but also easily causes accidents.

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0017] A glass bead safety warning manhole cover such as figure 1 As shown, it includes a well cover 1, a well seat 2 and a hinge 3. The hinge 3 is used to connect and limit the well cover 1 and the well seat 2. The bottom view of the manhole cover is like figure 2 As shown, the bottom surface is provided with a groove with the words "under construction", and glass beads are pressed in the groove. The cross-sectional view of the well cover is shown in 3. The angle between the hinged limit manhole cover and the well seat is 50°, that is, when the manhole cover is lifted, the angle between the manhole cover and the ground is 50°, such as figure 1 As shown, it conforms to the viewing angles of various vehicle drivers and pedestrians.

[0018] In the process of casting the manhole cover, the manhole cover is made of a composite material of cast iron and glass...

Abstract

The invention discloses a glass microsphere safety warning well cover. The glass microsphere safety warning well cover comprises a well cover, a well base and a hinge by which the well cover and the well base are connected and the well cover and the wall base are limited, wherein a limit angle of the hinge is between 30 and 60 degrees; the lower bottom surface of the well cover is provided with safety warning contents; and the safety warning contents are pressed on the well cover by glass microspheres. The glass microsphere safety warning well cover can reduce construction cost, improve working efficiency, warn and prompt running vehicles and pedestrians, and reduce traffic accidents.

Description

Technical field [0001] The invention relates to a manhole cover, particularly a manhole cover capable of warning pedestrians. Background technique [0002] In urban roads, traditional manhole covers for waterway, communication, gas, electricity and other pipelines are mostly produced and processed by iron materials and synthetic materials. In order to prevent theft and loss, they are generally designed as an integral design with the manhole seat, and the connecting hinges are in the manhole cover and Between well seats. When the manhole cover needs to be opened, the lifted manhole cover flips backwards, and is limited by the hinge of the shaft seat and maintains the angle of the manhole cover flipping backward. The manhole cover lifted during construction forms an obstacle on the road and is prone to various traffic accidents. Therefore, in various constructions on the road that require opening of the pipe and manhole cover, the construction party must additionally carry the rel...
