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

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0018] Such as figure 1 with figure 2 As shown, an anti-freezing well circle includes an outer circle 1 installed on the manhole, an inner circle 2 with a manhole cover 5, and a compression ring 3 arranged between the inner and outer circle; the outer well The ring 1 is a Z-shaped structure, and the inner well ring 2 is installed on the outer well ring 1; the manhole cover 5 is connected to the side of the inner well ring 2 by an arc-shaped bracket 4 inverted, and the manhole cover 5 is divided into an outer layer and a plastic sealing layer 8. The outer layer is a ring structure with a cover, and on the inner circumference of the ring there is a ring groove 9 for laying self-limiting electric heating cables. The encapsulation layer 8 is a polystyrene filled layer, and the bottom of the encapsulation has eight reinforcing ribs 6 arrayed around the center of...

Abstract

The invention discloses an anti-freezing well cementing ring. The anti-freezing well cementing ring comprises an outer walling crib installed on an inspection well, an inner walling crib provided with a well lid, and a compression ring arranged between the outer walling crib and the inner walling crib, wherein the outer walling crib is of a Z-shaped structure, the inner walling crib is installed on the outer walling crib, and the well lid is connected to the edge of the inner walling crib through arc-shaped supports in an overturning mode and is divided into an outer layer and a plastic sealing layer; the outer layer is of a circular ring structure provided with a lid body, and a circular groove where a self-temperature-limiting electric tracing band is laid is formed in the inner circumferential surface of the circular ring of the outer layer. By the adoption of the anti-freezing well cementing ring, the problem of freezing of a well cementing ring in winter is effectively solved.

Description

technical field [0001] The invention relates to the category of auxiliary equipment for well holes, in particular to a well ring for preventing freezing and cementing. 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 t...
