Crack the Nanjing Hanzhong Gate Bridge Construction Committee to trace in the end not shield their mistakes – Hanzhong Gate Bridge, railings cracking, Nanjing Construction Committee – Construction Mac
Railings cracks have basically been identified, the construction unit of money or get a new one will be
Hanzhong Gate Bridge just one year, and railings on the crack, Express series of reports on the matter, cause the relevant departments attach great importance. Yesterday, Nanjing Construction Committee is responsible for the scene who view the statement, the responsible person should be held responsible, not defend their blunders. Yesterday afternoon, the Nanjing Municipal Engineering Quality Supervision Station Leader arrived Express, out of the cracks on the railing of Hanzhong Gate investigation and the preliminary treatment suggestions.
Construction unit without authorization to use glue "paste" crack According to Nanjing Municipal Engineering
person in charge of quality inspection stations, Hanzhong Gate Bridge railing installation time for the June 2, 2008, by the Construction and Installation Company in Nanjing Root Construction, reported in the Express before, municipal bureau staff have found There railings cracks, has asked the original building, construction and design departments to identify the reasons for the implementation of treatment programs. However, in the Express reports, the construction unit even individual cementing material unauthorized use of closed cracks, the adverse social impacts. Quality inspection station official said that to do so is absurd, because the adhesive can not guarantee the strength and safety railings, purely a "paste ghost."
They had ordered the construction unit to take immediate and effective measures, from today on the railings for Wei Dang, and set up warning signs to ensure public safety, immediately organized relevant experts and construction, construction and design units to remove parts of the serious cracks inspection, testing and further analysis of the causes of cracks. According to test results, and then decided to further treatment advice. Next, all stone will crack the railings to be replaced, because stones procurement will take some time, it is estimated the repair work required more than a month.
Cracking the basic identification of the bridge railing
Municipal Engineering Quality Supervision Station official said, now railing has basically identified the reasons for cracking the next step, but also by the design unit of the bridge railing design review, and giving top priority in the city to inspect stone railing and eliminate hidden dangers.
Global China Construction Group Co., Ltd. Nanjing Company chief engineer Urban Design Institute of Caoming Xu told reporters, after they see, Qiaolan cracking due to abutment of a settlement, Hexi are soft, bridge fill soil subsidence crack the barrier , while the bridge is the main pile, the settlement small. Another reason is the continuous prestressed concrete bridge steel and granite stone Qiaolan shrinkage deformation coefficient is not, he and municipal engineering quality inspection stations that not reasonable to set the bridge railing, deformation caused by lack of coordination is the main root fracture reasons.
Then there is no way to avoid these problems then? Caoming Xu said, completely avoidable, such as the settlement of pile foundation can be used to play deep, pre-compression and other methods to solve the shrinkage deformation coefficient is inconsistent, you can set aside in the assembly Qiaolan reasonable gap to avoid. He admitted, stone construction techniques are required, many masons technology live a bit rough, responsibility, and seriously inadequate, and caused such a result. However, the good news is, experts agree that, after site inspection, the main structure of the bridge there is no major safety problems, the public need not worry.
Repair costs incurred by the construction unit Cut
Removal and replacement of the stone railings, will not crack over time again? Caoming Xu and quality inspection stations that charge per person: no. The reason is that some settlement has been basically put in place, the settlement will not be significant, and the same time, railing replacement units when the construction supervision of all parties under the weight, will greatly enhance the sense of responsibility and will not again put in place to install slot is not reserved for the situation. Quality inspection station official told reporters that the cost of replacing the bridge railing government certainly will not pay to be paid by the construction unit, the same time, they will pursue the responsible person's responsibility. He admitted that such a short time railing on the crack is definitely not normal, design, construction, supervision and other aspects are likely to have a corresponding responsibility, which they will be accountable and the results communicated to the Express.
Municipal engineering quality inspection stations this year has 180 administrative penalty, the lightest is the city's notice of criticism, while in leaving a bad record and to take administrative penalty, fine. This "bridge crack crack", will certainly be someone held accountable, Nanjing Construction Committee made it clear, strictly investigated, not shield their mistakes. Express reporter Bao Ming East
