Head of Investigation Team: The bottom of Ming Yue Wan is too big to rebuild.

Intern Shire This reporter Yi Tiecao Ming Yue Wan Problem Security room investigation team in charge, the state Construction Engineering Quality Supervision and inspection center of Dr. Huang Xuanming, is responsible for the detection of the main construction of Yue Bay housing. He told the China Youth Daily that they had tested concrete strength on all load-bearing walls and floors of 9 buildings, giving each floor a single evaluation result.　　Due to the confidentiality of the test report, the reporter could not get a complete report, but Huang Xuanming said that the most important load-bearing parts do not reach the level of concrete design strength. "Higher building, the ground floor requires concrete strength to reach C35 or C30, but many of the 9 buildings did not reach, some of the difference 1~2 intensity level."　　"Huang Xuanming said. He said that of these 9 buildings, some of them have been built to 18 floors, and some have been built to 9 floors. In the test results, they found some laws: different sections of the floor, concrete strength is not the same, a few layers of strength is not standard, but a few layers but can reach the standard.　　The most problematic floors are concentrated at the bottom, and the ground floor is the most force-bearing part of the whole building. "Need to strengthen the bottom floor, the level of substandard is more serious."　　Huang Xuanming said that because the entire bottom of the concrete strength is not very good, can not be demolished reconstruction. State Construction Engineering Quality Supervision and inspection center of the test report out, by the Chinese Institute of Architecture Research Institute to be responsible for strengthening the design of the project.　　On the part of the owners worried that even after strengthening the building safety or security problems, the demonstration expert Du Yihin said don't worry, "reinforcement can solve the problem." As for the time arrangement of the reinforcement works, Du Yihin said that the construction team and the owners agreed between, because it is still in the demolition phase, has not begun to strengthen.　　However, the owners of the Ming Yue Wan protection room have told reporters that they have not received any notice from the developers about the time they agreed to so far. As early as July, experts conducted a spot check on the wall concrete strength of 6 buildings in area B of Ming Yue Wan. Liu, director of Beijing Construction Quality Management Association, said: "At that time found that some do not meet the design requirements, the amount of substandard is relatively large, so several experts to discuss how to deal with." The result of the discussion is that technical reinforcement is in principle feasible, and there is a conclusion that the test can be done thoroughly. Liu told reporters that when the concrete strength is not up to standard, the first consideration is whether it can be reinforced, thereby reducing losses.　　He also stressed that reinforcement is not a problem, "there are two principles of reinforcement, the first is to ensure the use of security, and second, to ensure the important use of the function." "Reinforcement allows for 1.1 of the use of the function, such as wall thickening, room space is small." But this belongs to the secondary use function, belongs to the small area. "And finally live in accordance with expert opinion decided to demolish 6 of them on the ground part, Liu think, may be because the quality problem is too big, want to solve the problem, without interfering with the use of functions, can only be demolished.
