[0026] Please refer to Figure 1-Figure 3The utility model provides a transition structure between a double-layer double-wave guardrail and a concrete guardrail. The transition structure between the double-layer double-wave guardrail and the concrete guardrail comprises a concrete guardrail standard section 1, a concrete guardrail transition wall 3, a double-layer double-wave guardrail standard section 5 and a double-layer double-wave guardrail transition section 7, wherein the concrete guardrail transition wall 3 is connected to the concrete guardrail standard section 1, the double-layer double-wave guardrail standard section 5 is connected to the concrete guardrail transition wall 3 through the double-layer double-wave guardrail transition section 7, a side surface of the concrete guardrail transition wall 3 is provided with an assembly groove 8, an end of the double-layer double-wave guardrail transition section 7 away from the double-layer double-wave guardrail standard section 5 is installed in the assembly groove 8, and the highest surface of the double-layer double-wave guardrail transition section 7 is flush with the highest surface of the side surface of the concrete guardrail transition wall 3. Therefore, by utilizing the concrete guardrail transition wall 3 and the double-layer double-wave guardrail transition section 7 to connect the concrete guardrail standard section 1 and the double-layer double-wave guardrail standard section 5, a good transition connection is formed between the concrete guardrail and the double-layer double-wave guardrail to prevent cracking at the connection from affecting the protective effect. Moreover, an assembly groove is provided on the concrete guardrail transition wall 3, and the highest surface of the double-layer double-wave guardrail transition section 7 installed in the assembly groove is flush with the highest surface of the side of the concrete guardrail transition wall 3, so that the guardrail does not protrude from the highest surface of the concrete guardrail transition wall 3. On the premise that the guardrail plays a guiding role, it is prevented from tripping vehicles and correctly guiding vehicles out, thereby improving safety performance and also having good protective capabilities.

[0027] Specifically, the double-layer double-wave guardrail transition section 7 and the double-layer double-wave guardrail standard section 5 have the same structure, and both are composed of two double-wave guardrails installed side by side up and down, each double-wave guardrail includes a corrugated beam plate 71, a connecting assembly 73 and a column 75, one end of the column 75 is fixed on the road surface, and the corrugated beam plate 71 of the double-layer double-wave guardrail transition section 7 and the corrugated beam plate of the double-layer double-wave guardrail standard section 5 are connected and fixed to the end of the other end of the column 75 through the connecting assembly 73. The column 75 is connected and fixed at the connection between the corrugated beam plate 71 and the double-layer double-wave guardrail standard section 5 to strengthen the strength of the connection and improve the overall strength of the guardrail.

[0028] The connection assembly 73 is composed of a plurality of bolts. The bolt group passes through the corrugated beam plates of the double-layer double-wave guardrail standard section 5 and the double-layer double-wave guardrail transition section 7 to connect the two. The bolt connection is detachable and easy to disassemble and assemble.

[0029] Furthermore, the double-layer double-wave guardrail transition section 7 is fixed to the concrete guardrail transition wall 3 through a connecting member 9. The corrugated beam plate is anchored and connected to the concrete guardrail transition wall 3 through the connecting member 9. Specifically, the connecting member 9 is a steel bar.

[0030] In detail, the collision surface of the concrete guardrail transition wall 3 transitions from the slope surface of the concrete guardrail standard section 1 to a straight wall slope surface. It can be understood that the slope of the collision surface at one end of the concrete guardrail transition wall 3 gradually transitions to the concrete guardrail standard section 1 and forms a straight arm slope surface, so that the connection structure between the concrete guardrail transition wall 3 and the concrete guardrail standard section 1 is smoother.

[0031] In detail, the concrete guardrail transition wall 3 forms a height gradient from high to low from one end close to the double-layer double-wave guardrail transition section 7 to the other end. That is, the height of the concrete guardrail transition wall 3 at one end connected to the double-layer double-wave guardrail transition section 7 is high, and the height gradually decreases toward the other end to be the same as the height of the concrete guardrail standard section 1, so that the structure of the connection section between the two is smoother and more beautiful.

[0032] In another preferred embodiment, the transition structure between the double-layer double-wave guardrail and the concrete guardrail also includes a reinforced corrugated guardrail 10, which is a double-layer double-wave steel beam guardrail, and is also installed in the assembly groove 8, and is installed side by side above or below the double-layer double-wave guardrail transition section 7.

[0033] like Figure 1 As shown, the double-layer double-wave guardrail standard section 5 is also a double-layer double-wave guardrail. Specifically, the double-layer double-wave guardrail is a double-wave steel beam guardrail installed side by side up and down. By installing the double-layer double-wave guardrail, the strength can be effectively enhanced.

[0034] The double-layer double-wave guardrail and concrete guardrail transition structure provided by the utility model connects the concrete guardrail standard section 1 and the double-layer double-wave guardrail standard section 5 by utilizing the concrete guardrail transition wall 3 and the double-layer double-wave guardrail transition section 7, so that a good transition connection is formed between the concrete guardrail and the double-layer double-wave guardrail, preventing cracking at the connection from affecting the protective effect. Moreover, an assembly groove is provided on the side of the concrete guardrail transition wall 3, and the highest surface of the double-layer double-wave guardrail transition section 7 installed in the assembly groove is flush with the highest surface of the side of the concrete guardrail transition wall 3, so that the guardrail does not protrude from the highest surface of the concrete guardrail transition wall 3, and prevents the guardrail from tripping the vehicle while playing a guiding role, and correctly guides the vehicle, thereby improving the safety performance and also having good protection capabilities.

[0035] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
