Special crawling ladder for inspection well
The invention relates to a water supply and drainage facility, and aims at providing a special crawling ladder for an inspection well. The special crawling ladder can be beneficial to use and maintenance of the plastic inspection well. The special crawling ladder for the inspection well comprises a supporting cage and a crawling ladder body. The outer side of the supporting cage is supported by the inner wall of the inspection well. The crawling ladder body is fixed into the supporting cage. The upper end and the lower end of the crawling ladder body are bent so that the middle of the special crawling ladder can get close to the center of the supporting cage. The area between the inner wall of the supporting cage and the special crawling ladder is used by a user to go up and down. The special crawling ladder is located at the positions, below the mouth of the inspection well, of an inner cavity of a shell and an inner cavity of a base body. The special crawling ladder and the mouth of the inspection well are each in the reducing shape with the upper portion thick and the lower portion thin. One steel ring on the special crawling ladder is supported by the reducing part of the inner wall of the mouth of the inspection well. The special crawling ladder is ingenious in structure and convenient to use.
