Abstract

The invention relates to the field of urban infrastructure, in particular to an anti-falling safety supporting device special for an inspection well. The device comprises a supporting cylinder, the middle of the outer wall of the supporting cylinder is in threaded connection with a moving sleeve, an annular groove is formed in each of two sides of a threaded section positioned in the middle of theouter wall of the supporting cylinder, a rotating sleeve is arranged in each annular groove and rotates in the same under action of external force, and at least three supporting structures are uniformly distributed on the outer wall of each rotating sleeve. By adopting the device, falling of pedestrians or animals into a sewer due to falling into the inspection well can be prevented effectively,personal safety of the pedestrians or the animals is improved, and drowning accidents under the circumstance of accumulated water are avoided.

Description

technical field [0001] The invention belongs to the field of urban infrastructure, in particular to a special anti-falling safety supporting device for inspection wells that prevents pedestrians or animals from falling into the inspection wells. Background technique [0002] The sewer is a pipe used to remove sewage and rainwater in the city. In order to facilitate the inspection and dredging of the sewer, inspection wells are installed at the turns and branches of the sewer; in order to facilitate maintenance or cable replacement, underground cable channels for municipal use There are also inspection wells equidistant along the line. The wellhead of the inspection well is usually flush with the ground, and the size of the inspection wellhead is usually about 1 meter, so the wellhead of the inspection well needs a inspection well cover to prevent pedestrians from falling into the inspection well, and also prevent the foul gas in the sewer from entering the air in the city. ...
