Description

Technical Field

[0001] The invention belongs to the field of highway anti-collision safety, road engineering and energy conservation, and is specifically an assembled FRP-steel-lightweight ceramsite composite highway anti-collision guardrail, which is particularly suitable for engineering structures such as roads and bridges in high-altitude areas in the west. Background Art

[0002] The western region has complex terrain and changeable climate, so the design and material selection of road guardrails need to adapt to different geographical environments and climatic conditions. Affected by the terrain conditions, engineering structures such as roads and bridges are mostly built in the middle of the mountains, and the roads are mostly curved or continuous curves, which are a certain test of driving skills. It is expensive and difficult to achieve full line electrification. In addition, the western region is often at a high altitude and low temperature, and the road surface is prone to snow and ice accumulation, affecting the travel safety of vehicles. Through literature review, it is found that the existing vehicle anti-collision guardrails are mostly made of low-carbon steel or galvanized steel. For example, the base material of the traditional carbon steel highway guardrail is Q235 carbon structural steel, which has the problem of low strength grade. This means that when subjected to strong impact, its anti-collision performance may not be enough to effectively protect the safety of vehicles and passengers. In addition, when used outdoors, especially in high altitude and plateau environments, carbon steel guardrails will gradually rust and thin due to environmental influences, resulting in a gradual decrease in anti-collision performance and may eventually lose their protective function.

[0003] This patent takes into account the characteristics of FRP materials such as light weight, high strength, durability and high corrosion resistance. On the basis of existing road crash barriers, it fully utilizes the characteristics of abundant sunshine and strong wind in the high-altitude areas in the west, and innovatively proposes an assembled FRP-steel-lightweight expanded clay composite highway crash barrier. Summary of the invention

[0004] Purpose of the invention: In order to further improve the anti-collision performance and durability of existing road guardrails and make full use of clean new energy sources such as solar energy and wind energy, the present invention provides an assembled FRP-steel-lightweight expanded clay composite highway anti-collision guardrail. While improving the anti-collision performance of existing road guardrails, a solar energy and wind energy collection and storage device is designed to convert the clean energy into power for road lighting, traffic warnings and accident alarm linkage systems. At the same time, the collected electric energy can also be used for road pavement heating, melting snow and ice, and improving the safety of vehicle travel.

[0010] The FRP-steel-lightweight ceramsite composite columns and the FRP-steel-lightweight ceramsite composite crosspieces all adopt an FRP outer shell with a thin-walled steel pipe embedded in it. The inner wall of the thin-walled steel pipe is embedded with an FRP inner shell, and the FRP inner shell is injected with lightweight ceramsite anti-collision particles. That is, a tubular structure is formed by compounding a layer of FRP, a layer of thin-walled steel pipe (as an interlayer), and a layer of FRP together, and the interior is filled with lightweight ceramsite anti-collision particles, which are used to cushion impacts.

[0011] Preferably, the heat conducting device utilizes the electricity in the electric energy storage device, and generates heat by laying a heating cable under the road surface. The heating cable is powered on to provide the necessary heat for conduction to the road surface, thereby achieving the purpose of melting snow and ice in an efficient and environmentally friendly manner.

[0012] Preferably, the highway anti-collision guardrail is also provided with an intelligent detection device, which is arranged at the bottom of the FRP-steel-lightweight expanded clay composite column. The probe on the surface of the FRP-steel-lightweight expanded clay composite crossbar promptly transmits the impact position information to the warning device so that the color of the section road warning light automatically changes from green to red.

Among them, the density of the fiber composite material is only 1500-2000kg / m 3The density of FRP-steel-light ceramsite composite highway crash barrier is about 1 / 4 of that of traditional steel and 1 / 2 of that of aluminum alloy, while the tensile strength can reach over 3000MPa. The tensile strength of the FRP-steel-light ceramsite composite highway crash barrier in the present invention patent is greatly enhanced. Compared with the traditional metal crash barrier, it can improve the anti-collision performance of the guardrail, reduce traffic accidents caused by the failure of the guardrail, and protect the safety of drivers and passengers. In addition, FRP materials have good resistance to various media such as atmosphere, water, and general concentrations of acids, alkalis, and salts. They will not rust or break after rusting after long-term use, which greatly improves the corrosion resistance and durability of the FRP-steel-light ceramsite composite highway crash barrier.

This power generation mode reduces the use of non-renewable energy such as fossil fuels, reduces carbon dioxide emissions, and protects the surrounding ecological environment. In particular, the wind force in the western region is stronger than in other regions, the sunshine time is longer, and the light intensity is greater. Therefore, the present invention is particularly suitable for anti-collision guardrail structures such as roads and bridge projects in the western region.

[0024] 3. High degree of intelligence.

[0026] The present invention is equipped with an intelligent detection device. When a vehicle hits the guardrail, the probe receives a signal, and the warning light of the road section automatically changes from green, which indicates safe passage, to red to remind the vehicle that a traffic accident has occurred ahead. The accident location is automatically uploaded to the background control system, and an alarm is processed immediately, so that the accident section can be discovered in time to avoid missing the golden rescue time.

[0027] 4. Intelligently remove snow and ice to ensure smooth road conditions.

[0028] The present invention is provided with a heat conduction device. In the western region, due to the high altitude, the climate environment is relatively bad, and there is wind and snow weather all year round, snow and ice are easily generated on the highway. The collected solar energy and wind energy are converted into electrical energy and transmitted to the heat conduction device, and the heat conduction device transmits heat to the ground, which can quickly melt the snow and ice in a short time. The road safety level is improved and the hidden dangers of bad weather environment to driving safety are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Working principle of the present invention: Before use, prepare all components. The contact surface of the FRP-steel-light ceramsite composite column 1 and the ground is connected using an FRP-steel support 11 and an FRP high-strength bolt 4. The FRP-steel-light ceramsite composite crossbar 2 and the FRP-steel-light ceramsite composite column 1 are first connected with an FRP-steel fixing plate 8 and then fastened with an FRP high-strength bolt 4. The FRP-steel-light ceramsite composite crossbar 2 is in the form of two pieces.
