China's first tunnel rapid detection of car manufacturers: Wuhan Wu large outstanding science and technology limited liability company Published: February 2015 <br> <br> to 80 km / h speed driving ran a trip in the tunnel, the health of the tunnel Just master it. On February 9th, the first domestic tunnel rapid inspection vehicle, which was called “tunnel doctor†in the industry, officially went offline, marking China’s success in overcoming the worldwide difficulties in rapid tunnel detection and breaking the rapid measurement equipment and technology of foreign tunnels. monopoly.
At present, China is the country with the most highway tunnels in the world and the fastest growing speed. By the end of 2013, there were more than 10,000 tunnels in China and over 400 special tunnels, ranking among the top countries in the world. Due to geological conditions, terrain conditions, climatic conditions and various factors during the design, construction and operation of the tunnel, tunnels are more prone to diseases than ordinary roads during long-term use, such as cracking of linings, seepage of water in tunnels, and frost damage in tunnels. Lining corrosion and so on. These diseases not only affect the function of the tunnel as a fast and safe traffic channel, but also seriously jeopardize traffic safety.
Subject to the technology, currently most of the detection of disease in tunnels in China is based on manual inspections. Measurements are performed using naked eye observation and drilling methods. Visual observations are greatly affected by human factors. There are problems such as low efficiency, poor accuracy, and the inability to compare historic data. Although drilling methods are intuitive, they have slow detection speeds and can easily damage tunnel waterproof and drainage systems, affecting tunnel life. Both of the above methods are difficult to fully reflect the quality of the entire tunnel and its parts.
“Taking a 1km tunnel as an example, artificial measurement takes about 20 people to take 4 hours to complete.†Mr. Hu Dandan, vice president of Wuhan Wuda Excellence Technology Co., Ltd. introduced that the company’s first tunnel rapid measurement system independently developed by medium-sized truck As an on-board platform, several precision sensors are installed on the platform, with a speed of 80 km/h, daily mileage of up to 500 km, and a crack accuracy of 0.2 mm. Only one driver and one technical operator are required to pass. Nondestructive testing completes the collection of all tunnel data. 
Crash cushion car manufacturer: Xugong Truck Crane Company (hereinafter referred to as Xugong)
Published: February 2015 In February 2015, the collision-proof buffer truck of the expressway against the rear-end vehicle built by XCMG was officially offline. The vehicle minimizes the safety risks of construction vehicles, maintenance personnel, and traffic policemen handling accidents in the maintenance of urban roads and highways.
XCMG's crash cushioning energy-absorbing module of this crash-buffering vehicle is mainly composed of a car crash cushion and a guide sign frame, and acts as a buffer guard behind the construction work vehicle. In the event of a rear-end collision, it is possible to construct a buffer zone between the vehicle in question and the front construction work area, absorb the energy of the impact through deformation of the machine structure, and minimize the chance of collision of the protected personnel and equipment.
The car highlights in four areas. Firstly, the impact buffer energy absorption module adopts the new type “TMA-US-100K†imported from the Netherlands. Its shell is made of lightweight aluminum alloy sheet, and the aluminum alloy film honeycomb energy absorbing material is filled in the middle, and the controlled deformation will be effective. The collision energy is absorbed by the ground and the device has passed the CE certification of the European Union; secondly, the exterior of the crash cushion has been upgraded with a total of eight arc-shaped aluminum tube structures. When the collision occurs, the curved aluminum tube will be deformed first. Absorb huge impact energy from behind vehicles. After the energy overcomes the deformation rate of the aluminum tube, the cushion will absorb the rest of the energy, and double defenses will ensure the safety buffer; the third is the integrated electronic arrow sign, and the arrow sign can guide the left, right, and forbidden passages. Minimize the impact of construction on traffic flow, and ensure safety; Fourth, the rear of the cab is equipped with a crane to increase the auxiliary functions of the vehicle, which can be used to lift heavy objects during construction.
