Recently, in Shenhai, Dalian CityHighwaysThere was a serious one happeningTransportationAccident. OneBMW X6Sideslip occurs due to the failure of the brakes, and the impact is continuousIsolation belt, the vehicle was badly damaged. The cause of the accident was icy on the surface of the bend of the bridge, due to the severe cold weather and the heating companyBoiler roomThe cause of the smoke exhaust is that a section of the road about 100 meters long is covered with ice water, which makes the driver unable to control the vehicleTransportationAccidents. This incident has raised concerns aboutHighwaysAttention to the causes of icing on the bridge deck and the solution.
Mr. Li is a truck driver who often drives through Shenhai, Dalian CityHighwaysMakijoyi Bridge. On January 22, Mr. Li was driving through the bend of the Muchengyi Bridge when he noticed a large amount of snow and ice on the road. He quickly slowed down through the icy section, but was in front of him by a carBMW X6However, due to the failure of the brakes, a side slip occurred and a continuous impactIsolation belt, the vehicle was severely damaged. ThankfullyBMWNo people in the car were injured.
Mr. Li believes that if a large truck skiddies on the ice, it may rush outIsolation belt, falling from the bridge. Therefore, he considers it a serious safety hazard.
The reporter's investigation found that the Muchengyi Bridge is located in ShenhaiHighwaysOn the north side of the bridge, there is a heating companyBoiler room。Due to the current harsh winter,Boiler roomThe incessant burning caused a large amount of smoke to be exhausted, drifting down the north wind to the bridge deck. These smoke gases contain a large amount of water vapor, which condenses into water droplets at low temperatures and falls on the bridge deck to form ice. After observation, it was foundBoiler roomIn winter, once activated, it can lead to ice formation on the bridge deck.
The head of the heating company saidBoiler roomIt was built around 2007 using old-fashioned equipment and using a wet desulfurization process. Although the purpose is to meet environmental emission standards, the result is an increase in water vapor emissions. However, the heating company said it would move after the heating season endedBoiler roomand update equipment to reduce the impact on the surrounding environment.
CityTransportationThe department admits that there is an icing problem on the Makijoyi Bridge. They said that due to the high position of the bridge, northerly winds often blow through, resulting in a greater risk of ice on the bridge deck. Currently, they are working on solutions, including adding bridge deck heating equipment and improving the exhaust system.
Aimed at Shenhai in Dalian CityHighwaysThe following solutions can be considered for the icing problem of the Muchengyi Bridge:
1.MigrationBoiler room: Heating companies should move as soon as possibleBoiler roomto avoid smoke emissions directly above the bridge and reduce the possibility of ice formation.
2.Updating equipment: Heating companies are migratingBoiler roomAt the same time, consideration should be given to updating equipment and adopting a more environmentally friendly wet desulfurization process to reduce water vapor emissions and reduce the impact on the surrounding environment.
3.Add bridge deck heating equipmentTransportationDepartments may consider adding deck heating equipment to the bridge to increase deck temperature and reduce the likelihood of icing.
4.Improvement of the exhaust system: heating companies andTransportationDepartments can work together to improve the exhaust system of the heating boiler, reduce the impact of flue gas on the bridge deck, and reduce the risk of icing.
5.Regular inspection and maintenance:TransportationThe department should regularly inspect the bridge and clean up the ice and snow on the bridge deck in time to ensure that the road is smooth and reducedTransportationAccidents.
