Description

Technical Field

[0001] The utility model relates to the technical field of manholes, in particular to a manhole module brick. Background Art

[0002] Manholes, also known as sand wells in Hong Kong, Macau and Guangzhou, are underground spaces for the transfer and control of urban underground pipelines. Their ground entrances and exits are called sand well mouths or manholes. Manholes are usually covered by manhole covers. In cities, all public water supplies, sewage channels, telephone lines, and fiber optic networks may be connected through underground passages under manholes. Manholes are their exits to the ground and are covered by manhole covers. Most underground pipelines are straight. When a turn is required, a manhole is set at the turning position to prevent the straight pipeline from being blocked and to facilitate the installation of pipelines.

[0003] The construction of manholes requires the use of special manhole module bricks. The existing bricks are stacked alternately up and down and fixed with concrete. However, manholes are generally deeper during use. Stacking bricks too high during construction will cause the bricks to shift and easily collapse.

[0004] Therefore, it is necessary to provide a manhole module brick to solve the above problems. Utility Model Content
