The construction site was reinforced by a single pillar of the jinan roundabout。
The journalists were informed by the jenan city road administration that, after more than three months of intensive construction, the construction of a high-speed ying jia forest maintenance bridge in g2001 around the city will be completed in the near future. It is known that this was the first time in shandong province that the highway stand-by was reinforced。
In recent days, journalists have driven to g2001, around the town of zinan, to visit each other on site. At this point, the construction team of jinan king road engineering ltd. Is in the process of strengthening the stand alone pillar. At the site, a large construction convoy of forklifts, cranes, concrete pumps, etc., is working in an orderly and intense manner. Journalists noted that two new tubes had just been added next to the original stand, and that the workers had then injected concrete into the pipe。
“the two new pillars and bridges are compact and inoperable; however, they can provide a supporting support if the bridges are tilted.” wang qi, director general of engineering projects, told reporters that since may 16th, zenan king the construction team of road engineering ltd. Is stationed on the yin jia forest bridge to reinforce the four monolithic bridges of a, b, c and d. In accordance with the design programme of the transport planning and design institute of shandong province, the construction personnel were first reinforced on the basis of the original undertaking, then installed french plates, steel poles and reinforced the bridge in the form of self-concrete concrete。
According to the information received, the reinforcement of the high-speed yin forest around chinan is the first highway stand in shandong province. As a result of the reinforcement work, which was described by the relevant experts in the transport industry in my province, it was possible to improve the safety of highways and bridges by preventing the collapse of the bridge due to the uneven capacity of the monovalent continuum in the operation。
In the event of a security accident on a high-speed bridge, the result is often alarming. On 24 august 2012, the bridge at harbin sunming beach collapsed and four large trucks crashed, resulting in a tragedy of three deaths and five injuries. Indeed, the collapse of the junction bridge is not uncommon. For example, in july 2009, the bridge collapsed at the qinjin expressway terminal 800 metres away, causing six deaths and four injuries to five trucks。
In these accidents, overloads are often the focus of investigations. Because of the severe overload, the design life of highway bridges is often significantly compromised by these human factors。
At the 2013 economics and finance forum, shandong express group limited, chairman and secretary of the party, sun liang, “is still having a fairly high overload rate, and 40% of traffic accidents on the highway are caused by overload.” according to the leader of the highway industry in shandong province, a 49-ton cargo truck was able to reach 100 tons and 120 tons of cargo, and because of the increasing cost of highway maintenance due to overloading, the high-speed company had to increase its investment in maintenance to secure the road bridge. He cited the fact that the highway, which had been overhauled once in 10 years, was now overhauled once in six years, increasing the unit cost from $1. 5 million to $6 million。
