[0029] The reinforcement frame 1 of this embodiment is constructed from multiple steel bars assembled, tied, or welded together. The layout, material, and dimensions of the reinforcement frame are determined based on reinforcement calculations. The concrete U-shaped trough 2 can be cylindrical or rectangular. In the rectangular form, its width is a, its length is b, and its height is h. The U-shaped notch 6 on its lower side has a depth of h2 and a width of a2. Its material and dimensions must meet strength, anti-overturning, anti-sliding, and base stress requirements.

[0030] The concrete U-shaped groove 2 of the foundation structure of a signboard in the embodiment of the present utility model has sufficient strength, anti-overturning and anti-slip capabilities, which provides a fixed installation foundation for the upright pole 4 and the sign board 5, ensuring the safety and stability of the overall structure of the signboard; the U-shaped notch 6 provided on the lower side of the concrete U-shaped groove 2 provides a pre-buried space for the underground pipeline 8, which can solve the problem of signboard installation and construction under limited space and interference from the underground pipeline 8, avoid interference from the underground pipeline 8, and ensure the normal installation and construction of the signboard.

[0031] Furthermore, a plurality of anchor bolts 7 are pre-embedded in the concrete U-shaped trough 2 of this embodiment, and the upper ends of the anchor bolts 7 are bolted to the mounting base 3. The anchor bolts 7 not only connect the mounting base 3 and the concrete U-shaped trough 2 together, but also enhance the structural strength of the concrete U-shaped trough 2.

[0032] Furthermore, the anchor bolt 7 of this embodiment includes a first bent bolt 71 and a second bent bolt 72. The first bent bolt 71 includes a first vertical section, a bent section, a second vertical section, and a first horizontal section that are interconnected; the second bent bolt 72 includes a third vertical section, a second horizontal section, a fourth vertical section, and a third horizontal section that are interconnected. The first and second bent bolts 71 and 72 can strengthen the integrity of the connections between the upper and lower sections and the left and right sections within the concrete U-shaped channel 2, thereby increasing the structural strength of the concrete U-shaped channel 2.

[0033] Furthermore, in this embodiment, multiple anchor bolts 7 are symmetrically embedded in the concrete U-shaped groove 2, that is, multiple first bent bolts 71 are symmetrically embedded in the concrete U-shaped groove 2, and multiple second bent bolts 72 are also symmetrically embedded in the concrete U-shaped groove 2.

Furthermore, it protects the underground pipeline 8 and reduces the impact of construction vibrations on it. Specifically, the thickness of the sand cushion layer 9 is 10 cm.

[0035] The signboard foundation structure of this embodiment is embedded in a roadside slope, earthen shoulder, or green belt, and the foundation must meet bearing capacity requirements. If underground pipelines 8 are located below the signboard and space is limited, the pipelines 8 pass through the U-shaped notch 6. The signboard foundation must meet the requirements of the "Code for Design of Urban Road Traffic Facilities" (GB 50688-2011) and the "Code for Design of Highway Bridge and Culvert Foundations" (JTG 3363-2019).
