Problems solved by technology

However, in winter, especially in areas with relatively cold weather, the joint between the manhole cover and the well ring is prone to freeze in snowy weather. When opening the manhole cover, if the ice layer is thick, the ice layer covered on the manhole cover is thicker and is not easy to smash, but if you use too much force, it may cause the whole manhole cover to break

Abstract

The invention discloses an anti-freezing well ring. The anti-freezing well ring comprises an outer well ring mounted on an inspection well, an inner well ring mounted on the inspection well and provided with a well lid, and a compression ring arranged between the inner and outer well ring; the outer well ring is of a Z-shaped structure; the inner well ring is mounted in the outer well ring; a limiting lug is arranged on one side of the outer well ring; the limiting lug is an inclined surface and inclined towards the well hole; an annular groove is formed in the bottom end of inner circumference of the inner well ring; a scraping blade is arranged in the annular groove; the outer periphery of the inner well ring is wound with a temperature self-limiting electric heat tracing tape. The anti-freezing well ring is used for effectively solving the problem of well ring freezing in winter.

Description

technical field [0001] The invention relates to the category of auxiliary equipment for wells, in particular to an anti-freezing well ring. Background technique [0002] At present, with the development of cities and road reconstruction, a large number of communication and power cables installed on the ground need to be moved underground and re-laid. In order to facilitate future maintenance and replacement of these facilities. So just need to build a large amount of inspection wells to meet the needs of maintenance and overhaul replacement of project in the future. The appearance of these inspection shafts has indeed provided great convenience for future maintenance and inspection and replacement. However, in winter, especially in areas with relatively cold weather, the joint between the manhole cover and the well circle is prone to freeze in snowy weather. When opening the manhole cover, if the ice layer is thicker, the ice layer covered on the manhole cover is thicker ...
