Abstract
Description
Technical Field
[0001] This utility model relates to the field of road design, and in particular to a highly reliable carriageway. Background Technology
[0002] A carriageway, also known as a roadway or driveway, is a road used for vehicles to travel on. In the past, carriageways were simply obtained by directly dividing the land into sections. However, carriageways formed directly from the land had lower strength and a higher probability of developing potholes.
[0003] Therefore, concrete layers are often laid on the land to form driveways to ensure their strength. However, the concrete layers of commonly used driveways are laid directly on the ground. Due to the high density of concrete, it can easily cause localized pressure on the ground, making it prone to collapse after prolonged use, resulting in low reliability. In addition, the surface of the concrete layer is relatively smooth, making it easy for vehicles to slip, thus reducing safety.
[0004] In addition, some roadways have not been equipped with drainage structures, which can easily lead to water accumulation and affect the reliability of the roadways. Utility Model Content
[0005] The purpose of this invention is to provide a highly reliable roadway that can solve one or more of the above-mentioned problems.
[0006] According to one aspect of the present invention, a highly reliable roadway is provided, comprising a roadway body and a drainage mechanism.
[0007] The drainage mechanism is connected to the main body of the roadway.
[0008] The main body of the roadway includes a first crushed stone cushion layer, a first concrete layer, an asphalt tack coat, an asphalt layer, a first cement mortar layer, connecting blocks, and spacers. The first concrete layer is connected to the first crushed stone cushion layer, and the asphalt layer is connected to the first concrete layer through the asphalt tack coat.
[0009] Both the connecting block and the partition block are connected to the first concrete layer through a first cement mortar layer. The first concrete layer has a recess, and the partition block is located in the recess. The partition block passes through the drainage mechanism. One end of the connecting block is connected to the partition block, and the other end is connected to the asphalt layer.
[0010] The beneficial effects of this utility model are as follows: By setting a first crushed stone pad layer at the bottom of the main carriageway, a certain buffering effect can be achieved, reducing the local pressure of the carriageway on the ground and lowering the probability of land collapse. Furthermore, the asphalt layer on top of the carriageway provides high wear resistance and anti-skid performance, allowing vehicles to travel more reliably on the carriageway. Additionally, a drainage mechanism is provided, effectively reducing the probability of water accumulation on the carriageway and further improving its reliability. Moreover, a partition is also provided to isolate the carriageway from other roads, reducing the probability of vehicles detaching from the carriageway during operation.
[0011] In some embodiments, the drainage mechanism includes a second crushed stone cushion layer, a second concrete layer, a drainage seat, a second cement mortar layer, a partition block seat, and a manhole cover mechanism. The second concrete layer is connected to the second crushed stone cushion layer, the drainage seat is connected to the second concrete layer, the partition block seat is connected to the drainage seat, and the partition block is connected to the partition block seat. The drainage seat, partition block, and partition block seat together form a receiving cavity. The second cement mortar layer is connected to the inner wall of the receiving cavity, and the manhole cover mechanism is disposed on the second cement mortar layer. By setting the partition block seat and the drainage seat, the receiving cavity can be effectively formed in conjunction with the partition block, avoiding the obstruction of the partition block by the setting of the drainage mechanism. Moreover, the second cement mortar layer in the receiving cavity can effectively enhance its resistance to water seepage and water erosion.
[0012] In some embodiments, the manhole cover mechanism includes a manhole cover, a manhole cover base, and an angle iron. The angle iron is connected to the manhole cover base and is attached to a second cement mortar layer. The manhole cover is detachably connected to the manhole cover base. The angle iron effectively ensures that the manhole cover base is fully secured.
[0013] In some embodiments, the partition is 150mm above the top of the main carriageway, and the top of the main carriageway is flush with the top of the manhole cover.
[0014] In some embodiments, both the first crushed stone cushion layer and the first concrete layer are connected to the side of the drainage seat, which has a protrusion embedded in the asphalt layer. The protrusion improves the reliability of the connection between the drainage seat and the main roadway.
[0015] In some embodiments, the asphalt layer includes a fine-grained asphalt layer and a medium-grained asphalt layer, wherein the fine-grained asphalt layer is connected to the medium-grained asphalt layer, and the medium-grained asphalt layer is connected to the first concrete layer via an asphalt tack coat. The medium-grained asphalt layer has higher strength than the fine-grained asphalt layer, while the fine-grained asphalt layer has better skid resistance, thus ensuring that the asphalt layer has both high strength and good skid resistance.
[0016] In some embodiments, the thickness of the first crushed stone cushion layer can be between 240 mm and 260 mm, the thickness of the first concrete layer can be between 190 mm and 210 mm, the thickness of the medium-grained asphalt layer can be between 45 mm and 55 mm, and the thickness of the fine-grained asphalt layer can be between 25 mm and 35 mm.

[0026] The asphalt tack coat 13 is formed by spraying asphalt oil onto the first concrete layer 12. The asphalt layer 14 includes a fine-grained asphalt layer 141 and a medium-grained asphalt layer 142. The medium-grained asphalt layer 142 is obtained by laying medium-grained asphalt (i.e., asphalt with a particle size in the range of 2.36 mm to 0.075 mm) onto the asphalt tack coat 13. The fine-grained asphalt layer 141 is obtained by laying fine-grained asphalt (i.e., asphalt with a particle size in the range of 0.075 mm to 0.05 mm) onto the medium-grained asphalt layer 142. Thus, the fine-grained asphalt layer 141 is connected to the medium-grained asphalt layer 142, and the medium-grained asphalt layer 142 is connected to the first concrete layer 12 through the asphalt tack coat 13. In other words, the asphalt layer 14 is connected to the first concrete layer 12 through the asphalt tack coat 13.

[0029] Both the connecting block 16 and the partition block 17 are connected to the first cement mortar layer 15, that is, the connecting block 16 and the partition block 17 are fixedly connected to the first concrete layer 12 through the first cement mortar layer 15, and the partition block 17 is embedded in the recess 121. At the same time, one side of the connecting block 16 abuts against the partition block 17, and the other side of the connecting block 16 abuts against the asphalt layer 14.
[0030] The drainage mechanism 2 is also connected to the main body of the roadway 1. Preferably, the drainage mechanism 2 includes a second crushed stone cushion layer 21, a second concrete layer 22, a drainage seat 23, a second cement mortar layer 24, a partition seat 25, and a manhole cover mechanism 26.
[0031] The second crushed stone cushion layer 21 can be composed of stones, and the second concrete layer 22 can be composed of C25 concrete. The C25 concrete can be laid on the second crushed stone cushion layer 21 to form the second concrete layer 22, and the second concrete layer 22 is connected to the second crushed stone cushion layer 21.
[0032] The drainage seat 23 can be constructed from bricks and can be built on the second concrete layer 22 so that the drainage seat 23 is connected to the second concrete layer 22. One side of the first crushed stone cushion layer 11 and the first concrete layer 12 are connected to the side of the drainage seat 23. The drainage seat 23 can also be provided with a protrusion 231, which is embedded in the asphalt layer 14, thereby increasing the connection area between the drainage seat 23 and the main body of the roadway 1 and improving the connection reliability between the two.
[0033] The partition seat 25 can be made of stone. The partition seat 25 is placed on the drainage seat 23 and thus connected to the drainage seat 23. The partition 17 will pass through the drainage mechanism 2 and will be placed on the partition seat 25 and connected to the partition seat 25.
[0034] The installed drainage seat 23, partition 17 and partition seat 25 can together form a receiving cavity 101, and the second cement mortar layer 24 is connected to the inner wall of the receiving cavity 101.
[0035] The manhole cover mechanism 26 is disposed on the second cement mortar layer 24. Preferably, the manhole cover mechanism 26 includes a manhole cover 261, a manhole cover seat 262, and angle iron 263. The angle iron 263 is connected to the manhole cover seat 262 by welding, and the angle iron 263 is fixedly connected to the second cement mortar layer 24 by adhesive bonding.

After installation, vehicles can travel on the asphalt layer 14 of the main carriageway 1. The asphalt layer 14 has high wear resistance and anti-skid performance, enabling vehicles to travel more reliably on the main carriageway. Furthermore, the presence of a first crushed stone cushion layer 11 as a buffer effectively reduces the local pressure of the main carriageway on the soil, thereby reducing the probability of soil collapse.
