Description

Technical Field

[0001] The utility model relates to the field of urban construction, in particular to a fully silent and adjustable manhole cover. Background Art

[0002] With the development of urban construction and the improvement of people's living standards, the construction of sewers has become more and more developed. Manhole covers can be seen everywhere in residential areas, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet to the ground at every section. The section from the pipeline to the ground is called a manhole. The manhole mouth is usually flush with the ground, so a cover for covering the manhole is called a manhole cover.

[0003] The existing common covers still maintain the traditional production method. The current existing technologies all use manhole covers to be set in the seat. While ensuring the strength and front use of the manhole covers, the sound insulation effect is not considered. Since the current manhole covers have an unsatisfactory sound insulation effect, they have brought great noise troubles to people. For example, you can still hear the sound of flowing water in the dead of night, the construction team will make loud noises during the sewer construction process, and vehicles passing by will also make noises, etc., which all affect people's lives. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a fully silent and adjustable manhole cover, which solves the problem that the existing manhole covers have unsatisfactory sound insulation effects and bring great noise troubles to people.

[0006] A further improvement to the above solution is that the upper surface of the cover plate is provided with anti-slip strips and water leakage holes, and the upper surface of the fixed well ring is provided with annular strips and annular water leakage holes.

[0007] A further improvement to the above solution is that the anti-slip strips are provided in at least one group and can be spliced ​​on the upper surface of the cover plate to form pattern anti-slip strips, logo anti-slip strips, and font anti-slip strips.

[0008] A further improvement to the above solution is that a support beam for supporting the cover plate and a support ring connected to the support beam are provided on the lower surface of the cover plate, and reinforcing ribs are provided inside the support ring.

[0009] A further improvement to the above solution is that the reinforcing rib is an inverted triangle reinforcing rib, and a reinforcing block is provided at one end of the reinforcing rib.

[0010] A further improvement to the above solution is that a protrusion is provided at one end of the cover plate, and one end of the protrusion is connected to the support beam and the support ring to form a triangular support structure.
