[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0032] like Figures 1 to 6 The shallow anchored movable guardrail shown includes:

[0033] The guardrail assembly 1 includes at least two parallel beams 11 and a plurality of upright posts 12 evenly spaced and connected between the beams 11. It should be noted that the number of upright posts 12 can be one, two, three, or more, depending on the actual length of the beams 11. It should also be noted that the beams 11 can have a variety of shapes, including circular or square cross-sections, wavy shapes, or other shapes.

[0034] The leg assembly 2 includes a base plate 21, two support legs 22 fixedly connected to the base plate 21, and the two support legs 22 and the base plate 21 form a triangular structure. The two support legs 22 and the base plate 21 are fixed to the mounting grooves 23 at the ends of the two support legs 22 away from the base plate 21. The mounting grooves 23 extend perpendicular to the triangular structure surface, and the crossbeam 11 is installed in the mounting grooves 23. It should be noted here that the shape of the mounting grooves 23 is adapted to the shape of the crossbeam 11, and the shape of the mounting grooves 23 is set to match the shape of the crossbeam 11. It should also be noted that there are many ways to connect the base plate 21, the support legs 22, and the mounting grooves 23, which can be welded, screwed, hinged, or a combination of other connection methods.

[0035] The anchoring section 3 includes a guardrail assembly 1 and three leg assemblies 2. It should be noted that the anchoring section 3 is fixedly connected to the ground through three legs.

[0036] The standard section 4 includes a guardrail assembly 1 and a leg assembly 2. It should be noted that the standard section 4 is fixed to the ground via a leg, or supported by a leg.

[0037] Four standard segments 4 are connected to one anchoring segment 3 in a loop via a connecting assembly 5, with the base plate 21 of the anchoring segment 3 connected to the ground. The four standard segments 4 are connected to the anchoring segments 3 at both ends. After being connected via the connecting assembly 5, the mobile guardrail is fixed to the ground via the three legs of the anchoring segment 3 and supported by the legs of the four standard segments 4, providing stability and reducing the number of anchoring locations.

[0038] During the specific installation process, the anchoring section 3 and the standard section 4 are first assembled separately, and then the connecting assembly 5 is used to connect the anchoring section 3 and the standard section 4. Finally, the bottom plate 21 of the anchoring section 3 is connected to the ground, so that the installation of the mobile guardrail is completed; when removing the mobile guardrail, it is only necessary to disassemble the connection position between the bottom plate 21 and the ground to complete the removal.

[0039] The utility model enhances the stability and anti-overturning ability of the overall mobile guardrail through the triangular structural design formed by the base plate 21 and the two supporting legs 22, and further improves the stability of the system by connecting the base plate 21 of the anchoring section 3 to the ground; the guardrail adopts a modular combination of the anchoring section 3 and the standard section 4 to adapt to the requirements of roads of different lengths and shapes, among which the standard section 4 simplifies the installation of the non-anchoring part, and the anchoring section 3 is only used in necessary positions, which reduces the construction difficulty and the requirements for foundation conditions, reduces construction time and labor intensity, and at the same time reduces production and transportation costs, and is suitable for application scenarios of thin pavement layers and temporary sites.

[0040] In some embodiments of the present invention, Figure 2 、 Figure 3 As shown, each guardrail assembly 1 has three columns 12. The three columns 12 effectively improve the overall structural stability of the guardrail, enhance the impact resistance, and at the same time ensure uniform support of the crossbeam 11, reducing the stress burden of a single column 12.

[0041] In some embodiments of the present invention, Figure 2 As shown, the leg assemblies 2 of the anchoring section 3 are arranged in a one-to-one correspondence with the columns 12. This one-to-one correspondence between the leg assemblies 2 of the anchoring section 3 and the columns 12 can effectively improve the overall stability of the guardrail, allowing each column 12 to be independently supported, thereby distributing the load pressure and enhancing the guardrail's impact resistance and load-bearing performance.

[0042] In some embodiments of the present invention, Figure 3 As shown, the leg assembly 2 of the standard section 4 is arranged opposite to the middle column 12. The leg assembly 2 of the standard section 4 is used to support the crossbeam 11. The number of leg assemblies 2 is reduced while ensuring strength. On the one hand, it can play a supporting role, and on the other hand, it can also reduce material cost and weight.

[0043] like Figure 4As shown, to further secure the connection between the column 12 and the beam 11, the column 12 has extensions 12a at both ends. The extensions 12a are in contact with the end faces of the beam 11, and fixings are provided between the extensions 12a and the beam 11. The provision of the extensions 12a improves the connection strength between the column 12 and the beam 11, enhances the impact resistance and stability of the guardrail as a whole, effectively avoids structural deformation or falling off due to loose connections, simplifies the installation process, and improves assembly accuracy and construction efficiency.

[0044] like Figure 6 As shown, the connecting assembly 5 includes an inner sleeve 51 sleeved inside two adjacent beams 11, and a locking member connecting the inner sleeve 51 and the beam 11. By setting the inner sleeve 51 inside the beam 11, wear is reduced on the one hand, and the connection is made more uniform on the other hand.

[0045] In order to make the structure of the square tube more stable, Figure 2 、 Figure 3 As shown, the cross beam 11 and the column 12 are both square tubes. The square tube has excellent bending and torsion resistance, making the overall structure of the guardrail more stable and strong. The cross-sectional shape of the square tube makes it easier to connect with other components and increases assembly accuracy.

[0046] In some embodiments of the present invention, Figure 4 、 Figure 5 As shown, the support leg 22 is a round tube. The support leg 22 adopts a round tube design, which can evenly bear forces in multiple directions and has good bending and compression resistance, thereby improving the overall stability and durability of the guardrail.

[0047] In some embodiments of the present invention, the guardrail assembly 1 and leg assembly 2 are made of high-strength steel. High-strength steel offers excellent weather resistance, resisting corrosion and oxidation, extending the guardrail's service life and reducing maintenance costs. High-strength steel also offers strength while being relatively lightweight, simplifying transportation and installation, and improving construction efficiency.

[0048] In some embodiments of the present invention, the bottom plate 21 of the anchoring section 3 is connected to the ground with a ground spike. The ground spike has a diameter of 30 mm and extends 20 cm into the ground. The ground spike provides a strong grip, meeting the strength requirements without causing excessive damage to the foundation. It is convenient to install and remove, and helps improve the applicability and reuse efficiency of the guardrail.

[0049] Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
