[0002] The gland plate is a device relative to the manhole cover. It is a protective device used to cover underground pipeline wells and inspection wells. The difference between it and the manhole cover is that the manhole cover is a protective device used to cover the ground, while the gland plate is a protective device used to cover underground pipeline wells and inspection wells. The pipeline system is an indispensable infrastructure for modern cities. Because it follows the design and construction concepts of the past, in some areas, due to reasons such as engineering quality and equipment aging, the pipeline system has potential safety hazards. The existence of the gland plate can effectively protect the safe operation of the pipeline system and avoid pipeline leakage and environmental pollution. In order to improve the protection of personal safety, a gland plate is needed, but the existing gland plate still has the following shortcomings:

[0003] When the existing gland plates are used, since most of the gland plates have average overall sealing performance, they cannot protect the pipeline when it leaks. At the same time, garbage, weeds and other debris can easily enter the pipeline well, thereby affecting the normal use of the pipeline well and increasing maintenance costs, resulting in reduced practicality of the gland plates and reduced efficiency of use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-sealing pressure plate gland is proposed. Utility Model Content
