Description

Technical Field

[0001] This utility model belongs to the field of highway isolation technology, and in particular relates to a highway isolation guardrail base structure. Background Technology

[0002] Highway guardrail bases are a key component of road guardrail systems. Highway guardrail bases are mainly rectangular, circular, and triangular. Rectangular bases provide a larger support area, which can better distribute the weight and external forces of the guardrail. Most highway guardrail bases are installed using ground anchors pre-embedded in the road surface to increase the guardrail's stability, making them suitable for road sections with high stability requirements.

[0003] Currently, most highway guardrail bases are fixed using ground anchors. After a period of use, the mounting nuts on the ground anchor surface will rust due to rainwater erosion. Therefore, a highway guardrail base structure is needed that can protect the mounting nuts on the ground anchor surface through a protective structure, reducing the erosion of the mounting nuts by rainwater and ensuring the firmness of the highway guardrail base. Utility Model Content

[0004] The purpose of this utility model is to provide a highway guardrail base structure that can protect the mounting nuts on the ground anchor surface through a protective structure, reduce the erosion of the mounting nuts on the ground anchor surface by rainwater, and ensure the firmness of the highway guardrail base, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A highway guardrail base structure includes a base plate disposed below a pole. The top of the base plate has four symmetrical openings. Anchor bolts are disposed in the inner cavity of the openings. The bottom of the anchor bolts extends through to the bottom of the base plate and is fixedly connected to the road surface. Four symmetrical sleeves are fixedly connected to the top of the base plate. Sealing gaskets are fitted on the surface of the anchor bolts. Fastening nuts are threaded onto the surface of the anchor bolts. An installation head is fixedly connected to the top of the base plate. The surface of the installation head is fitted with a protective shell. The bottom of the pole is adapted to the top of the installation head. The bottom of the pole is in contact with the top of the protective shell. A fixing bolt is provided through the bottom of the pole.

[0006] Preferably, the top of the base plate is provided with a drainage groove, and the right side of the protective shell is provided with a drainage hole, and the drainage groove and the drainage hole are adapted to each other.

[0007] Preferably, two symmetrical connecting plates are fixedly connected to both sides of the upright, and a guardrail is provided between the two uprights. The upright is fixedly connected to the guardrail by the connecting plates and bolts.

[0008] Preferably, the sleeve is located above the opening, the mounting head is square, and the top of the mounting head extends to the outside of the protective shell.

[0009] Preferably, the protective shell is funnel-shaped, the fixing bolt passes through the upright and the mounting head to the other side of the upright, and the protective head is fixedly connected to the top of the upright.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model places the base plate at a suitable position on the road surface, allows the anchor bolts to pass through the opening and enter the inner cavity of the sleeve, and fixes the base plate with a sealing gasket and fastening nut. The protective shell is then placed on the surface of the mounting head, and the upright is placed on the top of the mounting head. The fixing bolt passes through the upright and the mounting head, thus achieving the protection of the mounting nuts on the surface of the ground anchor through the protective structure, reducing the erosion of the mounting nuts on the surface of the ground anchor by rainwater, and ensuring the firmness of the highway guardrail base.

[0012] 2. By using the drainage groove and drainage hole in combination, when water seeps into the top of the protective shell, the water will enter the inner cavity of the protective shell and flow out through the drainage groove and drainage hole, thus preventing water from accumulating in the inner cavity of the protective shell and ensuring the dryness of the inner cavity of the protective shell.

[0020] In the following description, embodiments of the highway guardrail base structure of this utility model will be described with reference to the accompanying drawings.

[0021] Example 1:

[0022] Figure 1-4 This invention illustrates a highway guardrail base structure according to an embodiment of the present invention. It includes a base plate 2 positioned below a vertical post 1. A drainage groove 11 is formed at the top of the base plate 2, and a drainage hole 12 is formed on the right side of a protective shell 9. The drainage groove 11 and the drainage hole 12 are compatible. Through the combined use of the drainage groove 11 and the drainage hole 12, when water seeps into the top of the protective shell 9, the water flows into the inner cavity of the protective shell 9 and flows out through the drainage groove 11 and the drainage hole 12, preventing water accumulation in the inner cavity of the protective shell 9 and ensuring its dryness. Two symmetrical connecting plates 13 are fixedly connected to both sides of the vertical post 1, and a guardrail 14 is provided between the two vertical posts 1. 1. The guardrail 14 is fixedly connected to the connecting plate 13 and bolts. The top of the base plate 2 has four symmetrical openings 3.
