[0002] Expressways, or highways for short, are roads designed for high-speed driving of cars. Expressways have different regulations in different countries, regions, eras, and scientific research fields. According to China's Highway Engineering Technical Standards (JTG B01-2014), expressways are multi-lane roads designed for cars to drive in different directions and lanes, with full access control. The average annual daily design traffic volume of expressways should be more than 15,000 passenger cars, with a design speed of 80 to 120 kilometers per hour.

[0003] After a certain period of use or when the traffic intensity is high, the ground of the existing expressways is prone to settlement, causing damage to the expressways and affecting driving safety. At present, the method to reduce the settlement of expressways is generally to use better fillers as the roadbed and compact the roadbed as much as possible, but the anti-sedimentation effect of such ground is not good enough and cannot meet the use requirements.

[0016] The following is a further detailed description through specific implementation methods:

[0017] like Figures 1 to 3 As shown:

[0018] A highway anti-settling structure includes a highway body composed of an asphalt pavement 1, a concrete road body 2, a roadbed 3 and a ground surface 4 arranged in sequence from top to bottom;

[0019] The anti-settling structure of the expressway also includes a plurality of anti-settling mechanisms 5, each of which is evenly arranged in the roadbed 3, and each of which is installed on the top of the ground 4. The anti-settling mechanism 5 includes a base 51, a support pipe 52, a plurality of extended branch pipes 54, a movable screw sleeve 55 and a steel frame 57. The base 51 is an inverted bucket-shaped structure, and the base 51 is placed on the ground 4. The support pipe 52 is fixedly installed on the base 51, and a plurality of extended branch pipes 54 are arranged on the side wall of the support pipe 52. The extended branch pipe 54 is used to increase the contact surface between the support pipe 52 and the roadbed 3, so that when the support pipe 52 and the extended branch pipe 54 are embedded in the roadbed 3, , anti-settling effect; a connecting thread 53 is provided on the outer side of the top of the support pipe 52, and the connecting thread 53 enables the movable screw sleeve 55 to be screwed on the top of the support pipe 52, and a steel frame 57 is provided at the movable screw sleeve 55. By adjusting the position of the movable screw sleeve 55 on the support pipe 52, the height position of the steel frame 57 can be adjusted. When pouring and constructing the concrete road body 2, concrete is poured into the anti-settling mechanism 5 simultaneously, so that the movable screw sleeve 55, the support pipe 52, the extended branch pipe 54 and the base 51 are all poured with concrete, and the steel frame 57 is poured in the concrete road body 2, so that the concrete road body 2 and the anti-settling mechanism 5 are fixed as one.

[0020] A plug 56 is installed at the top of the movable screw sleeve 55 to prevent the filler from entering the anti-settling mechanism 5 when the roadbed 3 is filled with filler.

[0021] The base 51 is in a bucket-shaped structure. The base 51 is connected to the support pipe 52 . Concrete is poured inside the base 51 , so that the pressure-bearing effect of the base 51 is better.

[0022] The specific implementation process is as follows:

[0023] When using the anti-settling structure of the expressway, firstly, the ground 4 is leveled and compacted, and then each anti-settling mechanism 5 is installed on the ground 4 so that the base 51 is close to the ground 4, and then the filler for constructing the roadbed 3 is filled on the ground 4 so that the roadbed 3 wraps the anti-settling mechanism 5, and then the roadbed 3 is compacted and leveled; then the steel frame 57 and the movable screw sleeve 55 of the anti-settling mechanism 5 are rotated, and the height position of the steel frame 57 is adjusted so that the steel frame 57 is adjusted to the top of the roadbed 3, and the plug 56 at the top of the movable screw sleeve 55 is opened; then concrete is poured on the roadbed 3 to construct the concrete road body 2, and the concrete enters the support pipe 52 and the extension branch pipe 54 and the base 51 through the movable screw sleeve 55, and the steel frame 57 is wrapped and embedded in the concrete road body 2, so that the concrete road body 2 is integrally formed with the anti-settling mechanism 5; finally, the asphalt pavement 1 is poured on the top of the concrete road body 2.

[0024] The anti-settlement structure of the expressway is provided with a plurality of anti-settlement mechanisms 5 on the ground 4, so that the anti-settlement mechanisms 5 are embedded in the roadbed 3. Meanwhile, when constructing the concrete road body 2, concrete is poured into the anti-settlement mechanisms 5, so that the concrete road body 2 and the anti-settlement mechanisms 5 are connected and combined into one. Each extended branch pipe 54 of the anti-settlement mechanism 5 can effectively enhance the contact area between the support pipe 52 and the roadbed 3, so that the roadbed 3 can better support the anti-settlement mechanism 5, thereby reducing the possibility of settlement between the concrete road body 2 and the asphalt pavement 1, and making the anti-settlement performance of the expressway better.
