[0002] With the acceleration of urbanization, the demand for new road construction has surged, and the continuous addition of asphalt layers has resulted in roads rising higher than manhole covers. In areas with poor geological conditions, such as soft soil, insufficient soil bearing capacity can easily lead to road foundation settlement. Construction quality issues can also cause road settlement, which in turn affects the proper use and maintenance of municipal inspection wells. The height difference between manhole covers and the road surface not only increases driving bumps and the risk of traffic accidents, but can also obstruct drainage systems and exacerbate urban waterlogging. Furthermore, manhole cover maintenance becomes more difficult and costly, sealing performance degrades, and the well structure may deform or damage, posing safety risks.

[0003] Therefore, it is necessary to provide a lifting and adjustable municipal inspection well structure to adapt to changes in the road surface, thereby solving problems caused by road subsidence, new paved roads, etc., ensuring the flatness and safety of the road, and improving the adaptability and functionality of municipal facilities.

[0028] See also Figure 2In one embodiment, a cavity 24 is defined between the outer side of the manhole cover 6 and the sand box 2. The cavity 24 is filled with a second sand 7. The top height of the second sand 7 is equal to the top height of the manhole base 1. The structure of the second sand 7 can be the same as that of the first sand 3.

[0029] See also Figure 1 In one embodiment, the lift-adjustable municipal inspection manhole structure 100 of the present invention further includes an asphalt layer 8, which is laid above the manhole base 1 and sand box 2 and surrounds the manhole cover 6. Specifically, the thickness of the asphalt layer 8 can be 4 cm, but is not limited to this. The specific material and structure of the asphalt layer 8 are well known to those skilled in the art and will not be described in detail here.

[0030] Combine Figures 1 to 4 The specific construction steps of the lift-adjustable municipal inspection well structure 100 of the present invention are as follows:

[0031] (1) Production and quality inspection of manhole cover 6 and sand box 2;

[0032] (2) After the well body is constructed, a well base 1 of an annular structure is cast on the top. Ring reinforcement 12 and stirrups 13 are arranged in the concrete layer 11 of the well base 1. The inner side of the well base 1 is cast together with four sand boxes 2. The four sand boxes 2 are evenly and symmetrically distributed on the inner side of the well base 1. Each sand box 2 is reserved with sand filling holes 22 and sand leakage holes 23 arranged up and down. The filling sand will be detachably inserted into the sand filling hole 22, and the sand leakage piece 5 can be detachably inserted into the sand leakage hole 23.

[0033] (3) According to the elevation requirements of the manhole cover 6, tighten the sand filling parts 4 and the sand leakage parts 5, and fill the well-graded first sand 3 (medium-coarse sand can be used) into the accommodating cavity 21 of the sand box 2 from the top of the sand box 2 to the predetermined elevation. During the filling process, vibration or other methods are used for compaction;

[0034] (4) Install the manhole cover 6. Place the manhole cover support 61 on the first sand 3 in the sand box 2. Fill the cavity 24 between the well base 1 and the manhole cover support 61 with well-graded second sand 7 until the height of the sand is flush with the top of the well base 1. Lay a 4 cm thick asphalt layer 8 on the top of the well base 1.

[0035] (5) When the road surface sinks and the road surface height is lower than the height of the manhole cover 6, dig the road surface along the periphery of the manhole cover 6, screw out the sand leakage piece 5, and use a vacuum pump or other device to extract the sand material in the sand box 2, lower the height of the sand material in the sand box 2, and stop extracting the sand material after the manhole cover 6 is flush with the road surface. Tighten the sand leakage piece 5, use the second sand 7 to fill the newly appeared cavity 24 between the manhole cover support 61 and the well base 1, and re-pave the asphalt around the inspection well to restore the road surface;

[0036] When the asphalt pavement is repaved and causes the pavement elevation to be higher than the height of the manhole cover 6, the pavement is dug up around the manhole cover 6, the first sand 3 between the manhole cover support 61 and the well base 1 is removed, the manhole cover 6 is lifted to the same elevation as the pavement using the suspension structure, the sand filling piece 4 is unscrewed, and sand is injected into the sand box 2 using a pressurizing device or an air compressor to fill the accommodating cavity 21 of the dense sand box 2. After ensuring that the height of the manhole cover 6 is consistent with the pavement elevation, the sand injection is stopped, the sand leakage piece 5 is tightened, the suspension structure is removed, and the second sand 7 is used to fill the cavity 24 between the manhole cover support 61 and the well base 1. The asphalt layer 8 is repaved around the inspection well to restore the pavement.

[0037] In summary, the liftable and adjustable municipal inspection well structure 100 of the present invention can lift and adjust the height of the well cover 6 to adapt to changes in road surface height, thereby solving problems caused by road subsidence, newly paved roads, etc., ensuring the flatness and safety of the road, and improving the adaptability and functionality of municipal facilities.
