Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a manhole cover structure with adjustable height to adapt to road surface slope. Background Technology

[0002] Currently, with the rapid development of my country's economy, urban infrastructure construction has entered a new cycle. Manhole covers are facilities installed in underground pipelines such as communication cables, power lines, gas pipes, and drainage pipes to facilitate access for maintenance personnel and connect to the surface.

[0003] With the rapid development of urban roads, the vast majority of newly constructed underground manholes adopt the precast reinforced concrete manhole scheme, and the spacing between manhole openings is 100 to 150 meters, resulting in a huge demand for manhole covers.

[0004] Traditional manhole covers are basically composed of a cover and a frame. The height and tilt angle of the cover and frame relative to the ground are not adjustable. When paving the road surface, there may be an elevation difference between the manhole surface and the road surface, or an elevation difference between the manhole surface and the sides of the road along the cross slope. This causes the newly paved road surface to fail to meet the cross slope requirements of the new road. This not only seriously affects the safety of pedestrians and vehicles, but also easily leads to excessive material laying, resulting in increased costs. Under long-term vehicle load, the connection between the frame and the manhole seat of traditional manhole covers is not stable enough. The concrete at the joint is prone to fatigue damage due to vibration. In addition, the traditional frame acts directly on the brick manhole, which can easily damage the manhole opening and cause it to sink. The asphalt concrete pavement around the manhole cover cracks and sinks, and the local road surface is severely damaged. Repair is labor-intensive and time-consuming, affecting the normal operation of the road and vehicles. Therefore, a manhole cover structure with adjustable height to adapt to the road slope is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a manhole cover structure with adjustable height to adapt to the road surface slope, so as to solve the above problems.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a manhole cover structure with adjustable height to adapt to road slope, including a manhole cover, an adjuster assembly, and a base. The adjuster assembly is fixedly installed on the base, and several of them are fixedly installed on the base. The bottom of the manhole cover abuts against the top of the adjuster assembly.

[0007] Preferably, a plurality of support platforms are welded and fixed to the top inner side of the base, and the adjuster assembly is snapped and fixed to the support platforms.

[0008] Preferably, the number of support platforms is twice the number of regulator components.

[0009] Preferably, the adjuster assembly includes an arc-shaped support, with hinge seats snapped and fixed to the bottom of both sides of the arc-shaped support. Each hinge seat has an adjusting bolt hinged to its bottom. A locking nut is threaded onto the adjusting bolt. The number of locking nuts is equal to the number of adjuster assemblies. The adjusting bolt passes through the middle of the support platform, and the locking nuts abut against the upper and lower sides of the support platform, respectively.

[0010] Preferably, the base includes an inner ring, an outer ring, and a connecting platform. The inner ring is located below the outer ring, and the connecting platform is welded and fixed to the top outer side of the inner ring. The outer ring is welded and fixed to the outer side of the connecting platform.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. Enables stepless height and tilt angle adjustment of manhole covers, meeting road cross slope requirements and keeping them level with the road surface, thus increasing the safety of pedestrians and vehicles.

[0013] 2. Improved tightness reduces material leakage during asphalt paving and manhole lifting, prevents the formation of holes, and alleviates subsidence around the manhole caused by repeated rolling of vehicle loads over long periods.

[0014] 3. The structure is simple and improves construction efficiency. The base can replace the limiting cylinder used in construction, eliminating the need to repeatedly clean asphalt and insert or remove the limiting cylinder. Attached Figure Description

[0019] The following is in conjunction with the instruction manual appendix. Figure 1-3 The technical solution of this utility model will be described through specific embodiments.

[0020] Example:

[0021] like Figure 1-3 As shown, the present invention provides a manhole cover structure with adjustable height to adapt to road slope, including a manhole cover 1, an adjuster assembly 2, and a base 3. The adjuster assembly 2 is fixedly installed on the base 3, and several of them are fixedly installed on the base 3. The bottom of the manhole cover 1 abuts against the top of the adjuster assembly 2.

[0022] During construction, the base 3 is inserted into the well opening, the regulator assembly 2 is installed on the base 3, and the regulator assembly 2 is adjusted to match the slope around the well opening. Then, the well cover 1 is placed on top of the regulator assembly 2 to complete the installation.

[0023] Several support platforms 31 are welded and fixed to the top inner side of the base 3. The regulator assembly 2 is snapped and fixed on the support platform 31. The number of support platforms 31 is twice the number of regulator assemblies 2.

[0024] The adjuster assembly 2 includes an arc-shaped support 21. Both sides of the bottom of the arc-shaped support 21 are fixed with hinge seats 22. The bottom of each hinge seat 22 is hinged with an adjusting bolt 23. The adjusting bolt 23 is threaded with a locking nut 24. The number of locking nuts 24 is equal to the number of adjuster assemblies 2. The adjusting bolt 23 passes through the middle of the support platform 31. The locking nuts 24 abut against the upper and lower sides of the support platform 31 respectively.

[0025] The base 3 includes an inner ring 32, an outer ring 33, and a connecting platform 34. The inner ring 32 is located below the outer ring 33. The connecting platform 34 is welded and fixed to the top of the outer side of the inner ring 32, and the outer ring 33 is welded and fixed to the outer side of the connecting platform 34.

[0026] Work steps: First, prepare several adjuster components 2 according to actual implementation needs, prepare bases 3 of corresponding size, and the number of support platforms 31 is twice the number of corresponding adjuster components 2. Before construction, screw the adjusting bolts 23 into the locking nuts 24 and then insert them into the support platforms 31. Screw the locking nuts 24 in again so that the two locking nuts 24 are pressed against the upper and lower sides of the support platforms 31. Hinge the hinge seats 22 at both ends of the arc-shaped support 21 to the top of the adjusting bolts 23 respectively, and rotate the locking nuts 24 on the upper and lower sides of the support platforms 31 to place each set of adjuster components 2 to the lowest position.

[0027] During asphalt paving, firstly, a steel plate is placed over the precast manhole opening. The paver lays the bottom layer of asphalt, the steel plate is manually removed, and loose material around the manhole opening is cleaned. After compaction by a roller, the base 3 is inserted into the manhole opening, and the asphalt aggregate around the base 3 is filled. The asphalt aggregate around the base 3 is then compacted with a plate rammer. The manhole cover 1 is then placed on top, and a release agent is applied to the surface of the manhole cover 1. The manhole cover 1 is then removed, and the asphalt aggregate around the base 3 is inspected for defects. Any defects are filled. The locking nuts 24 on the upper and lower parts of the support platform 31 are rotated to raise the height of the adjuster assembly 2. The slope direction of the road is observed, and the locking height of the adjusting bolts 23 on each set of adjuster assemblies 2 is adjusted to create an inclination angle at both ends of each set of adjuster assemblies 2. Through fine height adjustments, each set of adjuster assemblies 2 works in coordination, thereby ensuring that the upper surfaces of each arc-shaped support 21 are on the same plane and parallel to the road surface. Finally, the manhole cover 1 is placed in, the surrounding asphalt aggregate is leveled, and then compacted with a road roller.
