Problems solved by technology

[0006] (3) It is inconvenient to maintain during long-term use, and some rumble belts cannot be repaired;
[0007] (4) It requires professional mechanical personnel to operate, the efficiency is not ideal, and the quality is difficult to control;
[0008] (5) When the light is poor, vehicles may stray into the rumble belt, resulting in unnecessary noise;
[0009] (6) Part of the rumble belt is formed by destroying the road surface, which will cause water seepage on the road surface during construction and use, and lead to premature aging of the road surface
[0010] (7) It is impossible to remove snow and ice by itself in winter, and it needs to be cleaned by mechanical, manual or chemical methods (although the efficiency of mechanical snow removal is high, it cannot clean the thinner snow layer; the effect of manual cleaning is better, but the snow removal speed is slower and labor costs Higher; the chemical method uses snow melting agent to melt snow faster and has a better cleaning effect, but it will pollute the atmosphere and the soil on both sides of the road, destroy the ecological environment, corrode the road surface and facilities on the road, and reduce the service life)

Embodiment 1

[0045] A multi-functional rumble belt includes a plurality of rumble belt monomers 1, rubber plugs 2 and heating cables 3 which are assembled by mortise and tenon devices along the width direction; wherein, the rumble belt monomer 1 includes a first surface layer 11, the first base layer 12 and the first base layer 13, the upper layer of the rumble belt monomer is provided with a curved first surface layer 11, and the middle layer of the rumble belt monomer is provided with the first base layer 12 to bear and transmit the upper load, The lower layer of the rumble belt monomer is provided with a first bottom layer 13 that has undergone anti-slip treatment. The edge of the first bottom layer 13 is provided with a first inward slope 15. The first bottom layer is provided with two horizontal Through the first rectangular groove 14 of the first bottom layer, the heating cable 3 is laid in the first rectangular groove 14, the rumble belt monomer 1 is provided with a vertically penetr...

Embodiment 2

[0052] A multifunctional rumble belt includes a plurality of rumble belt monomers 1 , a rubber plug 2 , a heating cable 3 , a high-frequency noise early warning device 4 and a trapezoidal early warning device 5 formed by mortise and tenon arrangement along the width direction.

[0053] The rumble belt monomer 1 includes a first surface layer 11, a first base layer 12 and a first bottom layer 13, the upper layer of the rumble belt monomer is provided with a curved first surface layer 11, and the middle layer of the rumble belt monomer is provided with In order to bear and transmit the first base layer 12 of the upper load, the lower layer of the rumble belt monomer is provided with a first base layer 13 that has undergone anti-slip treatment, and the edge of the first base layer 13 is provided with a first inward slope 15, The first bottom layer is provided with two first rectangular grooves 14 horizontally penetrating through the first bottom layer, the heating cable 3 is laid ...

Embodiment 3

[0065] When the rumble belt has a three-level early warning function, during the construction of the first surface layer of the road, at the place where the rumble belt is laid, a groove with a width of 720 mm and a depth of 100 mm is perpendicular to the carriageway and has a rectangular cross-section (the specific depth depends on the design). The degree of compaction, the thickness of the first surface layer and other actual conditions shall be adjusted, but it is necessary to ensure that the depth of the groove after the compaction work is not less than 100mm), after the completion of the road surface compaction work, lay the heating cable 3 , and then put the rumble belt monomers 1 one by one in the groove, and connect them sequentially through the mortise and tenon devices of the rumble belt monomers with the three-level early warning function.

[0066] The width of the first rectangular slot is about 720mm.

[0067] The depth of the first rectangular groove is about 100...

Abstract

The invention discloses a new type of multi-functional rumble belt, which comprises a plurality of rumble belt monomers arranged and joined together by a mortise and tenon device along the width direction, a rubber cork, a heating cable, a high-frequency noise early warning device and a trapezoidal early warning device; The invention uses colored self-luminous recycled concrete to achieve the effect of easy identification for drivers, uses heating cables to achieve the function of melting snow in winter rainy and snowy weather, reduces the probability of vehicles rushing out of the road, and uses recycled concrete to actively respond to the national promotion of energy-saving and low-carbon technologies. It has the characteristics of convenient installation, low cost, resource saving, etc., and is suitable for long-term promotion and application.

Description

technical field [0001] The invention relates to the technical field of rumble strips, in particular to a multifunctional recycled concrete rumble strip. Background technique [0002] Rumble strips have proven to be an effective safety measure in reducing road departure accidents. According to research, the collision accidents caused by rushing off the road account for 64.4% of all collision accidents, and about 95.1% of the reasons are related to the driver. Further analysis also revealed that the main key causes of the accident were driver distraction, excessive steering compensation, poor directional control, excessive speed when cornering and drowsiness. According to the US Accident Analysis and Reporting System data, about 55% of fatal collisions can be reduced by the rumble belt. Furthermore, for two-lane roads in townships, this value increases to approximately 66%. [0003] Rumble strips are a relatively low-cost road safety measure. Economic analysis shows that th...
