Description

Technical Field

[0001] This utility model belongs to the field of urban public facilities technology, specifically relating to an adjustment device suitable for the stability and flatness of well rings. Background Technology

[0002] Manholes are important ancillary structures in urban underground infrastructure, widely used for the maintenance and installation of pipelines for power supply, water supply, drainage, sewage, and communications. They are typically installed at pipe junctions, bends, changes in pipe diameter or slope, and at regular intervals along straight pipe sections to facilitate routine inspection and maintenance. However, during the construction of road manholes, due to the inherent slope of urban roads, it is difficult to ensure that manhole covers are perfectly flush with the road surface. This unevenness causes vehicles to experience bumps when passing over them, affecting driving comfort and potentially leading to loss of steering control due to severe vibrations, increasing traffic safety hazards and threatening the safety of drivers and passengers. Furthermore, long-term bumps can accelerate damage to the manholes and surrounding road surfaces, increasing maintenance costs. Therefore, optimizing the installation process of manholes to ensure a smooth connection with the road surface has become a pressing technical problem to be solved in urban road construction. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one aspect of the present invention is to provide an adjustment device suitable for the stability and flatness of a well ring. The adjustment device includes a well ring, a fixed ring, and a flatness adjustment mechanism. The fixed ring is fixedly connected to the flatness adjustment mechanism and is in a vertical position. The well ring and the fixed ring are movably connected through the flatness adjustment mechanism and are in a horizontal position. The well ring and the flatness adjustment mechanism are in a vertical position.

[0004] Preferably, the flatness adjustment mechanism is evenly arranged around the perimeter of the well ring.

[0005] Preferably, the flatness adjustment mechanism has at least three sets.

[0006] Preferably, the shape of the fixing ring is consistent with the shape of the well ring.

[0007] Preferably, the shape of the fixing ring is circular or rectangular, similar to that of the well ring.

[0008] Preferably, bolt holes are provided around the well ring.

[0009] Preferably, the flatness adjustment mechanism includes a positioning bolt, an adjusting nut, and a fastening nut. The middle section of the positioning bolt is fixedly connected to the fixing ring. The positioning bolt passes through the bolt hole and is movably connected to the well ring. The adjusting nut is threadedly connected to the positioning bolt and is located below the fixing ring. The fastening nut is threadedly connected to the positioning bolt and is located above the fixing ring. The diameter of the positioning bolt is smaller than that of the bolt hole, and the diameters of the adjusting nut and the fastening nut are larger than those of the bolt hole.

[0010] Preferably, the flatness adjustment mechanism further includes a locking buckle, the bottom of which is hinged to the adjusting nut.

[0011] Preferably, the well ring is provided with a well cover.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention uses a combination of positioning bolts and adjusting nuts to precisely adjust the height of the manhole ring, ensuring it remains level with the road surface. This effectively prevents vehicle bumps caused by uneven manhole covers, improving driving comfort and safety. The dual locking structure of the fastening and adjusting nuts prevents loosening due to vehicle pressure or vibration, ensuring long-term stability of the manhole ring and reducing maintenance needs. The fixing ring is integrated with concrete pouring, ensuring a tight fit between the manhole ring and the road structure, improving load-bearing capacity and compressive strength, and extending the service life of the manhole. This device is suitable for manhole rings of different shapes and sizes, and the installation process is simple and efficient. It can be widely used in the construction and maintenance of manholes for urban roads and underground pipelines. By optimizing the manhole ring fixing method, it reduces repairs due to settlement or deformation, saves road maintenance costs, and improves the overall reliability of municipal facilities.

[0014] Additional aspects and advantages of this invention will become apparent from the description which follows, or may be learned by practice of this invention. Attached Figure Description
