Pins are evenly distributed at the bottom of the guardrail frame, and support plates are evenly distributed on both sides of the guardrail frame. A fixed base is provided on the side of the support plate closest to the guardrail frame, and through holes are symmetrically provided on the side away from the guardrail frame. A limiting groove is provided at the top of the fixed base. A bolt hole is provided on the side of the fixed base away from the guardrail frame, and an insertion hole is provided on the side of the guardrail frame closest to the fixed base. A fixing rod is installed in a plug-in configuration. One side of the fixing rod contacts the limiting groove. A limiting plate is installed on the end face of the fixing rod away from the guardrail frame. The limiting plate is installed with the end face of the fixing base away from the guardrail frame for limiting. The limiting plate is fixedly connected to the bolt hole by bolts. The pre-installed screw base includes a fixing plate, a threaded cylinder, and a pre-installed screw. A threaded cylinder is coaxially mounted on the bottom of the through hole. The top of the threaded cylinder is integrally set as the fixing plate, and the bottom of the threaded cylinder is integrally set as the pre-installed screw. The through hole and the threaded cylinder are fixedly connected by bolts.

[0008] Preferably, the support plate is evenly provided with plug-in tubes on the side near the guardrail frame, and the bottom of the guardrail frame is evenly distributed with bent bars, which are plugged into the inside of the plug-in tubes.

[0009] Preferably, the guardrail has evenly distributed snap-fit ​​bases on one side and evenly distributed snap-fit ​​plates on the other side.

[0010] Preferably, the fixing rod is provided with a columnar structure, and the limiting groove is opened with an arc-shaped structure, with the fixing rod and the limiting groove having the same center structure.

[0011] In summary, this utility model provides a guardrail for municipal road construction. This patented utility model employs a method where, after a fixed rod is inserted into a socket, a limiting plate and a fixed base are positioned at their ends. The limiting plate and bolt holes are then fixedly connected by bolts, achieving a secure installation of the guardrail frame and support plate, thus strengthening the guardrail frame's stability. Bending rods are provided on both sides of the guardrail frame. As the guardrail frame is inserted downwards, the bending rods are inserted into the socket, further limiting the guardrail frame and strengthening its fixation. The limiting groove positions the fixed rod, and the bolts then connect the limiting plate and bolt holes, further enhancing the guardrail frame's stability. Attached Figure Description

[0017] like Figures 1 to 3 As shown:

[0018] This utility model relates to a protective barrier for municipal road construction, comprising a guardrail frame 1, a support plate 2, a pre-installed screw base 3, and bolts 4. Pins 5 are evenly distributed at the bottom of the guardrail frame 1, and support plates 2 are evenly distributed on both sides of the guardrail frame 1. A fixed base 6 is set on the side of the support plate 2 closest to the guardrail frame 1, and through holes 7 are symmetrically opened on the side away from the guardrail frame 1. A limiting groove 11 is provided on the top of the fixed base 6, and bolt holes 12 are opened on the side of the fixed base 6 away from the guardrail frame 1. An insertion hole 13 is opened on the side of the guardrail frame 1 closest to the fixed base 6, and a fixing rod 14 is inserted and installed into the insertion hole 13. One side of 4 is in contact with the limiting groove 11. The end face of the fixing rod 14 away from the guardrail frame 1 is provided with a limiting plate 15. The limiting plate 15 is limited and installed with the end face of the fixing base 6 away from the guardrail frame 1. The limiting plate 15 is fixedly connected to the bolt hole 12 by bolts. The pre-installed screw base 3 includes a fixing plate 16, a threaded cylinder 17, and a pre-installed screw 21. The bottom of the through hole 7 is provided with a threaded cylinder 17 coaxial with it. The top of the threaded cylinder 17 is integrally set as the fixing plate 16, and the bottom of the threaded cylinder 17 is integrally set as the pre-installed screw 21. The through hole 7 and the threaded cylinder 17 are fixedly connected by bolts 4.

[0019] To address the issue of poor installation stability in existing technologies, this utility model patent employs the following technical structure: Pins 5 are evenly distributed at the bottom of the guardrail frame 1, inserted into the ground for fixed installation. Support plates 2 are distributed on both sides of the guardrail frame 1, with a through hole 7 on one side. A threaded cylinder 17 is pre-installed on the ground at the bottom of the support plate 2, with a pre-installed screw 21 integrally formed at the bottom. A fixing plate 16 is set at the top of the threaded cylinder 17, contacting the bottom of the support plate 2 for stable support. The support plate 2 and threaded cylinder 17 are then installed using bolts 4. The support plate 2 is fixedly installed on the ground, and the guardrail frame 1 is installed between the support plates 2, so that the guardrail frame 1 is clamped and installed by the support plates 2 on both sides. A fixed base 6 is provided on the side of the support plate 2 near the guardrail frame 1. A limiting groove 11 is opened on the top of the fixed base 6. The fixing rod 14 passes through the limiting groove 11 and is inserted into the insertion hole 13. A limiting plate 15 is provided at the end of the fixing rod 14. After the fixing rod 14 is inserted into the insertion hole 13, the limiting plate 15 is limited by the end face of the fixed base 6. The limiting plate 15 is fixedly connected to the bolt hole 12 by bolts, so as to realize the fixed installation of the guardrail frame 1 and the support plate 2, and strengthen the fixed installation of the guardrail frame 1.

[0020] In at least one embodiment, in order to further strengthen the fixed installation of the guardrail frame 1, a plug-in tube 22 is evenly arranged on the side of the support plate 2 near the guardrail frame 1, and a bent rod 23 is evenly distributed at the bottom of the guardrail frame 1, with the bent rod 23 plugged into the inside of the plug-in tube 22.

[0021] Specifically, after the pre-installation of the support plate 2 is completed, the guardrail frame 1 is fixedly installed by inserting it into the ground through the pins 5 set at its bottom. At the same time, the guardrail frame 1 is provided with bending rods 23 on both sides. As the guardrail frame 1 is inserted downwards, the bending rods 23 are inserted into the inside of the insertion tube 22 to further limit the installation of the guardrail frame 1 and strengthen the fixed installation of the guardrail frame 1.

[0022] In at least one embodiment, the guardrail frames 1 are installed by means of: having snap-fit ​​bases 24 evenly distributed on one side of the guardrail frame 1 and snap-fit ​​plates 25 evenly distributed on the other side, with the snap-fit ​​plates 25 inserted into the snap-fit ​​bases 24 to achieve fixed installation between the guardrail frames 1.
