[0070] When installing the standing stone 3, while aligning the first positioning groove 31 at the bottom of the standing stone 3 with the positioning plate 61, align the third positioning rod 81 with the third positioning groove 52. As the standing stone 3 is installed from top to bottom between the leaning stone 5 and the flat stone 4, the bottom of the third clamping plate 84 abuts against the leaning stone 5. Under the action of the leaning stone 5, the top of the third clamping plate 84 drives the third ring 82 to move toward the direction close to the standing stone 3, and the bottom of the third clamping plate 84 drives the third sliding rod 85 to move vertically downward, so that the third spring 83 is in a compressed state. As the standing stone 3 moves downward, the third clamping plate 84 gradually enters the third working groove 36 completely. Until the third clamping plate 84 moves to one side of the third clamping groove 53, the third clamping plate 84 can be clamped in the third clamping groove 53 under the action of the third spring 83, thereby further improving the stability and overall strength of the side stone.

[0071] The implementation principle of a road curb structure in the embodiment of the present application is as follows: during installation, the foundation is first poured, and the first steel bar 11 and the second steel bar 12 are buried in the foundation at the same time. Then, the first positioning hole 21 on the curb base 2 is aligned with the first steel bar 11, and the second positioning hole 22 is aligned with the second steel bar 12. The curb base 2 is inserted from top to bottom into the first steel bar 11 and the second steel bar 12 to complete the installation of the curb base 2. After the curb base 2 is installed, the first limiting groove 41 at the bottom of the flat stone 4 is aligned with the first steel bar 11, and the flat stone 4 is installed on the curb base 2. The second limiting groove 51 at the bottom of the leaning stone 5 is aligned with the second steel bar 12, and the leaning stone 5 is also installed on the curb base 2. After the flat stone 4 and the leaning stone 5 are installed, the reserved space between the flat stone 4 and the leaning stone 5 is adapted to the size of the standing stone 3.

[0072] Then install the standing stone 3, align the first positioning groove 31 at the bottom of the standing stone 3 with the positioning plate 61, align the second positioning rod 71 with the second positioning groove 42, and align the third positioning rod 81 with the third positioning groove 52. As the standing stone 3 is installed from top to bottom, the bottom of the standing stone 3 first abuts against the first clamping plate 62, so that the first clamping plate 62 rotates in the direction close to the hinge plate 63, driving the first spring 64 to be in a compressed state; until the first clamping plate 62 moves into the first clamping groove 32, the first clamping plate 62 rotates in the direction away from the hinge plate 63 under the action of the tension of the first spring 64, so that the first clamping plate 62 is stuck in the first clamping groove 32; at the same time, the bottom of the second clamping plate 74 abuts against the flat stone 4, and under the action of the flat stone 4, the top of the second clamping plate 74 drives the second ring 72 to move in the direction close to the standing stone 3, and the bottom of the second clamping plate 74 drives the second slide rod 7 When the locking cam 72 is in the unlocking state, the locking cam 72 is in the unlocking state, and the locking cam 72 is in the unlocking state, so that the second locking cam 72 is unlocked and the locking cam 72 is locked.

[0073] The present application also discloses a method for constructing road curbstones, comprising the following steps:

[0074] S1, pouring the foundation and burying the embedded steel bar group 1 in the foundation;

[0075] S2. Position the curb base 2 on the foundation by embedding the steel bar group 1 and install and fix the curb base 2;

[0076] S3, install the side stone 5 and the flat stone 4 in sequence on top of the side stone base 2;

[0077] S4. Install the standing stone 3 between the side stone 5 and the flat stone 4. Fix the standing stone 3 to the side stone base 2 through the first fixing assembly 6. Fix the standing stone 3 to the flat stone 4 through the second fixing assembly 7. Fix the standing stone 3 to the side stone 5 through the third fixing assembly 8.

[0078] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
