Three people died of high-speed tire burst in 236 cases of Hangzhou Bay Cross Sea Bridge in July (photo)

Several artificial rainfall brought a little cool to people in parts of Zhejiang Province, but the high temperature heat wave showed no sign of abating At 3:10 p.m yesterday, the ground temperature of Hangzhou Bay sea crossing bridge has risen to 65.7 ℃ -- in the past week, the average maximum temperature of the bridge deck is 64 ℃, of which the highest record has exceeded 67 ℃ According to statistics, in July, there were 236 cases of car tire explosion in Hangzhou Bay Cross Sea Bridge, including 4 cases of high-speed tire explosion It has been said that the high ground temperature of the bridge is mainly due to its steel beam structure - the bridge body is easier to absorb heat than the ordinary road surface However, in the current high temperature weather in Zhejiang Province, the highway pavement temperature is more than 50 ℃, which is normal Yesterday, high-speed traffic police in Hangzhou, Taizhou and Huzhou said that in the past week, the number of vehicle tire bursts in their high-speed road area was basically the same - about 30% higher than usual, and their daily response to tire bursts was about 20 or 30, "not including the vehicles solved by themselves or found and helped by the patrol of rescue vehicles." Three people died in 65 accidents caused by a flat tire last month On July 26, a Mercedes Benz car collided with a large truck in the Tiantai section of the three high-speed highway Ms Mei, the female driver of Mercedes Benz, was seriously injured The accident was related to a flat tire Police officer Chen, who dealt with the accident, said that when it was more than 50 meters away from the truck, the right tire of Mercedes Benz suddenly burst, and then Mercedes Benz seriously deviated to the right and lost control It first hit the right side of the guardrail, then the car's left front half of the body The bumper under the rear of the truck is bent and straight into the right rear of the truck The Benz car is seriously deformed This is actually just one example of the recent frequent blowout accidents Yesterday, the Zhejiang high-speed traffic police team said that they did not make statistics on the accidents of high-speed tires in the province, but there were 65 accidents in July Of the 65 accidents, two were fatal, with three people dead: one occurred in Jiaxing section of the Shanghai Hangzhou Expressway at 1 a.m on July 3 At that time, an Iveco left rear tire burst, the vehicle collided with the right guardrail and then overturned Four people in the car, except the driver, did not fasten their seat belts, resulting in two deaths and one injury On the other hand, it happened in Shaoxing section of Hangjin Quzhou expressway, which was more than 9am on July 28 A truck stopped in the fast lane after a flat tire was hit by a vehicle behind it, killing one person on the truck The high-speed traffic police said regretfully that the accident might not have been so serious, because at that time the truck was able to park on the hard shoulder What kind of car is easy to blow out in hot weather? Drivers should have a look at the Hangzhou high-speed traffic police who have made an analysis and investigation of 123 tire bursts in the four-day hot weather in the area 1 Of the 123 cases of tyre blowout in the eight truck, 99 cases were tyre blowout in the truck, accounting for 80% The reason is that the truck runs on the road for a long time, and the tire runs with high load; secondly, some trucks are overloaded, so that the tire bears too much pressure In addition, some truck owners are trying to save money by loading their cars with old tires or retreading them 2 If the car is more than 30000 km long, the proportion of the car with the most tire bursts is only 20%, but because the car is small and the speed is fast, the risk of tire bursts is higher In the 24 cases of small car tire burst, 17% of them drove below 30000 km, and 83% of them drove above 30000 km The high-speed traffic police said that, in general, cars rarely change tires within 30000 km, which may mean that 30000 km is the "node" of tire use - if not, the probability of tire blowout may rise sharply However, most of the 24 cars that had a tire blowout were small bread and low-end cars, and the high-end cars had a low probability of tire blowout The high-speed traffic police said that the reason may be that the high-end car itself has good tire quality, and many high-end cars are equipped with tire pressure monitoring systems, which can effectively prevent tire blowout 3 Of the 24 high tire burst cases in the rear wheel of the car, 18 occurred in the car But in terms of tyres, rear wheel blowout accounts for the majority, accounting for 15, 83% There is also a reason Because most car owners will change the front wheel to the rear wheel after using the tire for a certain period of time, and change the front wheel to a new tire - that is to say, the rear wheel itself is an old tire at this time, and the probability of tire blowout is relatively high At the same time, there is also a situation that can be ignored When the front wheel is rolled to a foreign body and bounces up, it is easy to puncture the rear wheel and cause a flat tire How to deal with the high temperature tire burst? The high-speed traffic police gave some suggestions First of all, regular inspection shall be carried out In addition to timely replacement of tires that have exceeded the service life, good tires shall pay attention to their tire pressure The tire pressure is generally normal between 2.2kpa and 2.5kpa They suggest that in summer, the tire pressure should be set at the lowest limit of this range, i.e 1-2kpa Speeding is the most important thing In high temperature weather, the ground temperature is high, which will heat the tire If the car is still speeding at this time, the temperature of the tire will be higher and higher Once "hot inflation" occurs, it is easy to blow out the tire If you drive on the road for a long time, you'd better go to the service area more often Parking means that you can let the tires rest and cool down In case of a flat tire, remember to hold the steering wheel tightly with both hands, try to control the steering wheel from turning by itself, and let the car drive in a straight line in the original direction - if you have already turned, do not over calibrate, in fact, it is difficult to calibrate Once the direction is controlled, it is necessary to quickly shift into low gear and use the engine to drag the vehicle Do not step on the brake or pull the handbrake until the engine traction has controlled the speed, so as to avoid the vehicle rolling or overturning accident Quick news: a bus burst and burst through the floor in Hangzhou this morning The bus No 4559 (Yellow Sea type) from Hangzhou passenger transport center to bus north station, went to dawn village, Desheng When the left rear tire burst suddenly, four passengers felt uncomfortable After the hospital inspection, two of them suffered from skin injury and the other two left without any obstacle According to the on-site audience, the floor of the bus has been blown through a hole Three passengers are injured accidentally Two women and one man are injured on their feet At present, the cause of the accident is under investigation In view of the continuous high temperature in the near future, the bus department will immediately strengthen the maintenance to ensure the operation safety.
