Anti-freezing well ring

Abstract

The invention discloses an anti-freezing well ring. The anti-freezing well ring is characterized by comprising a well ring mounted on an inspection well and a well lid mounted on the well ring; a plurality of lugs are arranged at the contact joint of the well lid and the annular base plate of the well ring; the well lid is reversely connected to the edge of the well ring by use of a cambered support; the well lid is divided into two layers, namely an outer layer and a plastic sealing layer; the outer layer is of a circular ring structure with a cover, and an annular ring for laying a temperature self-limiting electric heat tracing tape is formed in the inner circumferential surface of the circular ring. 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 a well hole, in particular to a well ring for preventing freezing. 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 co...

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
