Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a construction device for compacting asphalt concrete around inspection wells. Background Art

[0002] When compacting asphalt concrete around inspection wells, due to space limitations and high construction difficulty, the problem of insufficient compaction often occurs, which has a negative impact on the service life and safety of the road. During the paving and rolling process of the middle and lower asphalt layers, affected by the raised elevation of the inspection well, the compaction of the asphalt concrete around the inspection well by the roller is poor, resulting in subsequent settlement around the well.

[0003] Chinese patent document CN 118273197 A discloses a sleeve device for the construction of rain and sewage inspection well covers on asphalt concrete pavements, but this device cannot address the problem of the raised inspection well, resulting in insufficient and ineffective compaction around the inspection well during construction; Chinese patent document CN 204000950 U discloses a transition manhole cover for compacting the periphery of inspection wells on asphalt pavements, and it also has the above problems. It cannot overcome the influence of the raised inspection well and cannot cross the inspection well for compaction work around the well, so there are defects in use and improvement is needed. Summary of the Utility Model

[0004] The utility model provides a construction device for compacting asphalt concrete around inspection wells, which solves the problem that during the construction process, due to the space limitation of the road surface layer, it is not possible to effectively compact the asphalt concrete around the inspection well without damaging the inspection well.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a construction device for compacting asphalt concrete around inspection wells, including a clamping unit detachably sleeved outside the inspection well, a cover plate detachably provided on the clamping unit, a plurality of pressing plates are circumferentially arranged on the outside of the clamping unit, and inclined plates are provided on the pressing plates. The cover plate and the plurality of inclined plates cooperate for the roller to walk and compact the road surface.

[0006] In a preferred solution, the clamping unit includes a docking sleeve sleeved on the inspection well, a plurality of adapter seats are slidably connected circumferentially on the outside of the docking sleeve, and adjacent two adapter seats are in contact with each other. The pressing plates are arranged on the outside of the adapter seats.

[0007] In a preferred solution, a step is provided on the inner side of the docking sleeve, and the inner side wall of the step is in contact with the outside of the inspection well.

[0008] In a preferred solution, a plurality of sliding grooves are evenly distributed circumferentially on the outside of the docking sleeve, and screws are provided on the inner side of the adapter seats, and the screws slide in the sliding grooves.

[0009] In a preferred embodiment, an arc-shaped backing plate is provided at the bottom of the adapter base. The inner side of the arc-shaped backing plate fits against the outer side of the docking sleeve. An arc-shaped groove is provided on the upper side of the arc-shaped backing plate, and a gap is formed between the arc-shaped groove and the docking sleeve. The cover plate includes a disc and a sleeve. The sleeve is threadedly connected to the docking sleeve and is located within the gap.

[0010] In a preferred embodiment, the thickness of the sleeve matches the size of the gap.

[0011] In a preferred embodiment, a first threaded hole is provided on the side wall of the arc-shaped groove. One side of the screw is located within the first threaded hole, and the adapter base is connected to the pressure plate by the screw.

[0012] In a preferred embodiment, two second threaded holes are provided in parallel on the outer side of the adapter base. The pressure plate includes a mounting plate.

Specific implementation manners

[0026] As in Figures 1-5 , a construction device for compacting the asphalt concrete around the inspection well includes a clamping unit 2 detachably sleeved outside the inspection well 1, a cover plate 3 detachably provided on the clamping unit 2, and a plurality of pressing plates 4 arranged on the outer side of the clamping unit 2 in the circumferential direction. An inclined plate 402 is provided on the pressing plate 4, and the cover plate 3 and the plurality of inclined plates 402 cooperate for the roller of the road roller to walk and roll.

[0027] Since the inside of the inspection well 1 needs to be compacted layer by layer during the construction and paving of asphalt concrete, however, due to the inspection well protruding from the road surface and the inspection well having a circular cross-section, the roller of the road roller cannot directly apply sufficient force to compact the asphalt concrete around the inspection well 1, resulting in certain quality hidden dangers in later use. And if the road roller directly presses over the inspection well 1, there is also a risk of damaging the inspection well 1, with low construction efficiency and poor construction quality guarantee.

[0028] In a preferred solution, the clamping unit 2 includes a docking sleeve 201 sleeved on the inspection well 1. A plurality of adapter bases 203 are slidably connected to the outer side of the docking sleeve 201 in the circumferential direction. Two adjacent adapter bases 203 are in contact with each other, and the pressing plate 4 is arranged on the outer side of the adapter base 203.

[0029] The docking sleeve 201 can be first positioned outside the inspection well 1. Since the inspection well 1 is made of concrete pipe, the inner diameter of the docking sleeve 1 is slightly larger than the outer diameter of the inspection well 1, reducing the frictional resistance during installation. At the same time, the adapter seat 203 can be quickly installed on the docking sleeve 201 to adjust the position of the docking sleeve 201. Preferably, four adapter seats 203 are provided, and the four adapter seats 203 are respectively vertically arranged. Two of the adapter seats 203 are along the walking direction of the road, and the other two adapter seats 203 are perpendicular to the walking direction of the road. The inclined plate 402 on the pressing plate 4 can guide the roller of the road roller to cross the inspection well 1 after passing over the cover plate 3, and then press the periphery of the inspection well 1, completing the compaction work of the asphalt concrete around the well. At the same time, the cover plate 3 and the inclined plate 402 cooperate to provide a foundation for the road roller to walk, avoiding the problem of the road roller directly contacting the inspection well 1. The cover plate 3 and the clamping unit 2 cooperate with strong bearing capacity, and can evenly distribute the load from the road roller, so as to ensure the consistency of the asphalt concrete around the inspection well 1 during the process of being laid layer by layer. Until the last layer of asphalt concrete is laid, the clamping unit 2, the cover plate 3 and the pressing plate 4 can be completely removed, and the road roller directly presses over the inspection well 1, compacting the asphalt concrete to a state roughly flush with the top of the inspection well 1. The overall construction is efficient and the construction quality is good.

[0030] In a preferred solution, a step 204 is provided on the inner side of the docking sleeve 201, and the inner side wall of the step 204 fits against the outer side of the inspection well 1.

[0031] By providing the step 204, the contact area between the docking sleeve 201 and the outer side wall of the inspection well 1 is reduced, thereby reducing the overall friction force, improving the convenience and smoothness of operation. At the same time, the step 204 ensures full coverage of the periphery of the inspection well 1, providing guarantee for subsequent compaction.

[0032] As Figures 6-8 shown in, in a preferred solution, a plurality of sliding grooves 202 are evenly distributed along the circumferential direction on the outer side of the docking sleeve 201, and a screw 5 is provided on the inner side of the adapter seat 203, and the screw 5 slides in the sliding groove 202.

[0033] By providing the sliding groove 202, the distance between the screw 5 and the adapter seat 203 can be adjusted as needed, so that it can be quickly installed with the docking sleeve 201. At the same time, the bottom of the adapter seat 203 completes the compaction work of the asphalt concrete in the external area of the docking sleeve 201.

[0034] In a preferred solution, an arc-shaped backing plate 205 is provided at the bottom of the adapter seat 203, the inner side of the arc-shaped backing plate 205 fits against the outer side of the docking sleeve 201, an arc-shaped groove 206 is provided on the upper side of the arc-shaped backing plate 205, and a gap 211 is formed between the arc-shaped groove 206 and the docking sleeve 201. The cover plate 3 includes a disc 301 and a sleeve 302, and the sleeve 302 is threadedly connected to the docking sleeve 201, and the sleeve 302 is located in the gap 211.

[0035] By adjusting the gap 211, sufficient installation space can be provided for the cover plate 3. The sleeve 302 applies a downward force on the screw 5. The screw 5 serves as a force transmission part and transmits the force to the docking sleeves 201 and the adapter seat 203 on both sides, ensuring strong overall bearing capacity and uniform load distribution, and providing a guarantee for the paving and compaction of the asphalt concrete around the inspection well 1.

[0036] In a preferred solution, the thickness of the sleeve 302 matches the size of the gap 211.

[0037] The sleeve 302 fits more closely with the docking sleeve 201, the overall structural rigidity is stronger, and the anti-impact effect is better.

[0038] In a preferred solution, a first threaded hole 207 is provided on the side wall of the arc-shaped groove 206. One side of the screw 5 is located in the first threaded hole 207, and the adapter seat 203 is connected to the pressure plate 4 through the screw 5.

[0039] By providing the first threaded hole 207, the installation is convenient, the adjustment is continuous, and the use effect is good.

[0040] In a preferred solution, two second threaded holes 209 are provided in parallel on the outside of the adapter seat 203. The pressure plate 4 includes a mounting plate 401. The inclined plate 402 is connected to the mounting plate 401 through a plurality of support ribs 403. Through holes 404 are symmetrically provided through the mounting plate 401, and the screw 5 is inserted into the through holes 404 and the second threaded holes 209.

[0041] The cross-section of the mounting plate 401 is "L-shaped". It is firmly connected to the side wall of the adapter seat 203 through the screw 5. Then, the support ribs 403 provide sufficient support for the inclined plate 402 from the bottom, can withstand the impact from the roller of the roller compactor, have stable bearing capacity, and are convenient to use.

[0042] In a preferred solution, a notch 405 is provided between the inclined plate 402 and the mounting plate 401. The notch 405 facilitates the installation and removal of the screw 5.

[0043] The operator can conveniently install, remove and adjust the pressure plate 4 through the notch 405, and the use is simple.

[0044] In a preferred solution, contact surfaces 208 and relief surfaces 210 are respectively provided on both sides of the adapter seat 203, and two adjacent contact surfaces 208 are in contact.

[0045] The adjacent contact surfaces 208 can serve as installation references, ensuring high installation accuracy and good effect for the adapter seats 203 with their respective positions and angles. At the same time, it avoids the passivation of the surface 210 on the adapter seat 203 and the safety risks brought by the sharp corners during taking. The overall weight is smaller, and the construction is safer and more stable.

[0046] The above embodiments are only the preferred technical solutions of the present utility model and should not be regarded as limitations to the present utility model. The protection scope of the present utility model shall be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present utility model.
