Abstract

The invention discloses a novel expressway guardrail which comprises bases, the bases are buried in the two sides of an expressway, guardrail mechanisms are fixedly connected to the top ends of the bases, the bottom ends of vertical rods and the top ends of the bases are integrally formed, transverse bars are arranged on the front sides, and the backs of the transverse bars are attached to the vertical rods. The transverse bars are fixedly connected with the vertical rods through bolts, connecting sleeves are arranged above the vertical rods, the multiple vertical rods are connected through the transverse bars, the bottom ends of the connecting sleeves are connected with the top ends of the vertical rods in a sleeving mode, the connecting sleeves are fixedly connected with the vertical rods through bolts, and supporting frames are arranged above the connecting sleeves. The bottom ends of the supporting frames and the top ends of the connecting sleeves are integrally formed. According to the novel expressway guardrail, the noise reduction operation is achieved through a sound insulation mechanism while the functions of a conventional guardrail are guaranteed, the noise reduction capacity is further improved under the action of first sound insulation cotton and second sound insulation cotton so that the influence of night driving noise on nearby residents can be reduced, practicability is high, and popularization is convenient.

Description

technical field [0001] The invention relates to the technical field of expressway guardrails, in particular to a novel expressway guardrail. Background technique [0002] Expressway, referred to as expressway, refers to a highway specially designed for cars to travel at high speed. Expressways have different regulations in different countries and regions, in different eras, and in different research and academic fields. According to China's "Technical Standards for Highway Engineering" (JTGB01-2014), expressways are multi-lane roads that are designed for cars to drive in separate directions and drive in separate lanes, and all access and exit are controlled. The highway guardrail is an important part of the highway. The existing highway guardrail does not have the function of noise reduction, which causes the sound of traffic at night to affect the rest of nearby residents. Contents of the invention [0003] The purpose of the present invention is to provide a novel expr...
