July 27, netizens reflected that the inner wall of the half-mountain tunnel black fire layer fell off very seriously, a few days ago the netizen passed here, the next lane above there is a fire coating fell off, fortunately did not cause casualties and property damage. On the morning of the 28th, Hangzhou network reporters went to the scene to verify. In the tunnel opened a circle back and forth, the reporter did not find dropped on the ground fire layer, but the top fire layer fell off more, deep shallow, mottled, with the beautiful goldfish dropped a large number of fish scales, vaguely can also see repair marks. Speed is generally faster, the vehicle driving in which there are safety hazards living along the Qiushi elevated residents Mr. Liu's home stone bridge, in Linping to work, the half-mountain tunnel is his daily commute to work. Mr. Liu recalled that shortly after the completion of the half-mountain tunnel, there was a
coating
shedding phenomenon, falling on the ground every day someone will come to clean up, repair is always there, but no effect. The half-mountain tunnel has a speed limit of 80 km/h, but there are 100 people per hour. Therefore, the speed of the half-mountain tunnel is generally faster, if the falling object hits the vehicle windshield directly, it is very likely to block the driver's driving line of sight, which is a hidden danger to the high-speed vehicles. Since the opening of the Half Mountain Tunnel, Mr. Liu has passed through work almost every day, and although he has not been hit during this period, he is afraid of this phenomenon. Mr. Liu reflected that many car owners complain about this phenomenon quite a lot, although the damaged maintenance units will give compensation, but it will still be very troublesome. Fire layer shedding phenomenon has never rooted out the half-mountain tunnel was completed at the end of March 2012, only three months from the tunnel line open, the paint on the top of the tunnel began to appear small area off the situation. At that time, the person in charge said that the fall of the fire coating, is the previous few days of heavy rain, wet weather caused by the cause. In May 2013,
fire-resistant
in the Half Mountain Tunnel began to fall, but fortunately there was no accident that hit the moving vehicle. At that time, there have been a lot of mass reaction, maintenance units also have maintenance, but the phenomenon of fire layer shedding seems to have not been cured. Builder response: September will carry out a major renovation of the half-mountain tunnel is the construction of Hangzhou underground space construction and development center, the maintenance unit is Hangzhou Road and Bridge Company, but once the fire layer falls off, the repair party is the ground center, the maintenance unit is responsible for the clearance of falling objects and regular fire layer inspection. Lu manager said that the fire layer paint fall off is a sudden phenomenon, regular inspection can not be fully confirmed. In layman's terms, because of the rain weather, humid air, will make the fire layer coating absorb water, such as water to a certain extent, the paint will produce shedding phenomenon, paint fall off is suddenly off, so there is no good preventive measures. In 2014, the fire layer paint fell off seriously, the ground center of the fire layer under a major renovation, when the method was reinforced by steel nails. And this year, because it has been raining for some time now, the fire layer paint fell off very seriously.
Manager Lu said that in September this year, when the weather is dry, there will be another major renovation, this renovation will be all the fire layer good and bad to push away, re-start, rather than the previous repairs. Now the company has generally determined the renovation plan, in consultation with the traffic police to establish a specific time for the re-construction of the fire layer.
