Abstract

The invention discloses an anti-freezing inspection well. The anti-freezing inspection well is characterized by comprising an outer well ring mounted on the 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 and a limiting lug is arranged on one side of the outer well ring; the inner well ring is mounted in the outer well ring and the well lid is connected to the inner well ring; an annular bracket is arranged between the inner well ring and the outer well ring; a thermal insulating part is arranged between the annular bracket and the well lid. The anti-freezing inspection well 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 antifreeze inspection well. 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 thick...
