[0002] The blind road is a kind of barrier-free municipal facility that is convenient for the visually impaired to travel. However, due to road conditions, the blind road is often used in conjunction with various municipal engineering wells (such as sewage wells, sewer wells, inspection wells, communication wells, and cable TV signal transmission cables). Wells, cable wells, inspection wells, etc.) cross, in this case, the blind road either has frequent turns, or is simply interrupted, which has caused great inconvenience to the travel of the visually impaired, which is different from setting blind roads. The original intention of barrier-free municipal facilities is not in line with

Embodiment Construction
[0020] The invention discloses a "well cover with blind passage function which is not easy to slide and rotate". The following descriptions of embodiments of the invention are merely exemplary in nature, and are in no way intended to limit the application or uses of the invention.
[0021] According to the regulations on blind roads in the "Code for Barrier-free Design of Urban Roads and Buildings", blind roads are divided into two types: driving blind roads and prompting blind roads. The walking blind road is a blind road used to instruct the disabled to walk forward, and the walking blind road is in the shape of a bar; the prompting blind road is used for the starting point, end point and turning point of the walking blind road, and the prompting blind road is in the shape of a dot.
[0022] Similarly, the "manhole cover with the function of blind passage that is not easy to slide and rotate" of the present invention is also divided into two categories, namely "the well cove...

The invention relates to a well cover being less prone to slippage and rotation and having the functions of a blind sidewalk, the well cover comprises the function of the go-ahead blind sidewalk and the function of prompting the blind sidewalk, and strip-shaped bulges or dot-shaped bulges are arranged on the upper surface of a load-bearing main body of the well cover for playing the function of the go-ahead blind sidewalk and the function of prompting the blind sidewalk respectively. The strip-shaped bulges and the dot-shaped bulges are arranged according to the requirements of codes for accessibility design in urban highways and buildings. A positioning block is arranged on the lower surface of the well cover being less prone to slippage and rotation and having the functions of the blind sidewalk. A positioning groove is reserved in the position corresponding to the positioning block on the well peripheral plane supporting the well cover being less prone to slippage and rotation and having the functions of the blind sidewalk according to the size, the shape and the position of the positioning block. When the blind sidewalk is intersected with various municipal engineering wells inevitablely, frequent turns and interruptions of the blind sidewalk can be avoided, thereby providing great convenience for visually impaired people for going outside.
Description
technical field [0001] The invention proposes a manhole cover with blind passage function which is not easy to slide and rotate, and belongs to the technical field of municipal engineering material preparation. Background technique [0002] The blind road is a barrier-free municipal facility that is convenient for the visually impaired to travel. However, due to road conditions, the blind road is often used in conjunction with various municipal engineering wells (such as sewage wells, sewer wells, inspection wells, communication wells, and cable TV signal transmission cables). Wells, cable wells, inspection wells, etc.) cross, in this case, the blind road either has frequent turns, or is simply interrupted, which has caused great inconvenience to the travel of the visually impaired, which is different from setting blind roads. The original intention of accessible municipal facilities is inconsistent. Therefore just need a kind of facility that provides more conveniences for...
