Well lid module with adjustable base

Abstract

The invention provides a well lid module. The well lid module comprises a base, a lifting ring and a well lid, wherein the base is provided with a substantially cylindrical main body and a flange radially outwards extending from one end of the main body; at least one lap of internal thread is formed on the inner wall of the main body; the lifting ring is provided with a substantially cylindrical main body and a diameter enlarging part positioned at one end of the main body; at least three laps of external threads are formed on the outer wall of the main body of the lifting ring; the diameter enlarging part forms an opening of the lifting ring; the well lid is used for covering the opening; the main body of the lifting ring is mounted in the main body of the base, so that the external threads of the lifting ring can be screwed with the internal thread of the base; and through rotation, the lifting ring selectively moves relative to the base along a longitudinal axis. The well lid modulefurther comprises a base rail for joining with a cement base; the rail base is provided with a substantially cylindrical main body; and the well lid module is mounted relative to the base rail to enable an adjusting device to adjust an inclined angle of the base relative to the base rail.

Description

technical field [0001] The present invention generally relates to a manhole cover assembly, especially a manhole cover assembly used in road construction, wherein the inclination of the base surface of the manhole cover assembly relative to the base rail can be adjusted as required and is equipped with a quick locking device. Background technique [0002] Manhole covers are widely used in urban road construction. With the continuous expansion of urban construction, the quality requirements for road paving are getting higher and higher, and the requirements for manhole covers are also getting higher and higher. It is required that the manhole covers should be as flush as possible with the ground when laying. [0003] In addition, in traditional road construction, after years of use, the road surface may collapse, resulting in unevenness between the manhole cover and the road surface, which is likely to cause damage to vehicles and affect the appearance of the road surface.

Problems solved by technology

[0003] In addition, in traditional road construction, after many years of use, the road surface may collapse, resulting in unevenness between the manhole cover and the road surface, which is likely to cause damage to vehicles and affect the appearance of the road surface

In addition, the pavement needs to be refurbished after many years of use. In the process of re-paving, most of the existing manhole covers need to be completely abandoned and re-manufactured and installed, which is time-consuming, laborious and costly

[0004] In addition, traditional manhole covers are rarely equipped with proper locking devices, so they are prone to bouncing up and down and making noise when vehicles pass by the manhole cover
