An installation device for a manhole cover

Abstract

A mounting device for an inspection well cover comprises an inspection well opening (110) formed in the top end of an inspection well (100) and the inspection well cover (2) connected with the inspection well opening (110) in a matched mode. A bearing transverse beam column (1) is transversely arranged in the inspection well (100) and located below the inspection well opening (110). A bearing component (3) internally provided with a containing cavity (30) is arranged in the bearing transverse beam column (1). Two deformable fixed arms (21) distributed in bilateral symmetry are integrally arranged at the bottom of the inspection well cover (2). The two deformable fixed arms (21) are inserted into the containing cavity (30) of the bearing component (3) by means of elastic deformation.

Description

technical field [0001] The invention relates to the field of inspection shaft cover connection, in particular to an installation device for inspection shaft covers. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. It is called the inspection shaft, and the inspection shaft mouth is usually flush with the ground, so a cover is needed to cover the inspection shaft cover of the inspection shaft. The existing inspection shaft covers are usually made of reinforced cement, metal, reinforced plastics and other materials. The inspection well mouth is matched, because the inspection well cover is made of metal material, and there is no fixed device to fix it, usually encounters the patronage of thieves, once the thief steals the ...

[0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. It is called the inspection shaft, and the inspection shaft mouth is usually flush with the ground, so a cover is needed to cover the inspection shaft cover of the inspection shaft. The existing inspection shaft covers are usually made of reinforced cement, metal, reinforced plastics and other materials. The inspection well mouth is matched, because the inspection well cover is made of metal material, and there is no fixed device to fix it, usually encounters the patronage of thieves, once the thief steals the inspection well cover, it is easy to cause accidents, such as pedestrians falling into the inspection well Waiting for an accident
