Text of news flash

Group investment, located in Baimajing Town, Danzhou City, Hainan Province. The project consists of three independent islands, Island 1 is a tourist service area, and Islands 2 and 3 are mainly residential areas. Mumianyuan District, located on No. 3 Island, is composed of 19 30-38-story high-rise buildings, some of which have been delivered and the rest suspended for some reasons. Since the beginning of March, the owners of kapok garden on Haihua Island No. 3 have reflected the load-bearing walls and columns of underground garages in the district through different channels, including large area cracking, concrete pulverization and serious corrosion of steel bars. Owners are worried that these problems will seriously affect the structural safety of high-rise buildings and pose a threat to their personal and property safety. In the video provided by the owner, the owner gently kicked the load-bearing column of the basement with his toes, resulting in large chunks of concrete falling off, exposing rusty steel bars. Scratch the surface of the steel bar with your fingers to make it brown and powdered. It is reported that the kapok garden needs to be snapped up by lottery because of its beautiful environment and hot sales. On March 28, some netizens reflected on the "leadership message board" the problem of barbaric extraction of open land on Haihua Island No. 3 Island. After on-site inspection, Danzhou Housing and Construction Bureau found that some of the frame columns and shear walls in the basement were corroded and the protective layer fell off. A notice has been issued to the participating units to organize the construction, design, supervision, construction units and owners' representatives to coordinate the rectification and reform on the site. On May 10, the relevant departments of the Hainan Provincial Housing and Construction Department confirmed that a group of experts had been sent to the scene for investigation. The Danzhou municipal government has coordinated residential construction and other relevant departments to inspect the basement of the kapok garden three times. On March 4, the leaders and technicians of Danzhou Housing and Construction Bureau conducted an on-the-spot investigation and found that the basement ventilation system was never turned on and rusty, and the fire protection system failed acceptance. The test report shows that 9 of the 11 concrete compressive strength specimens are unqualified and the content of chloride ion exceeds the standard by nearly 5 times. The owner suspected that the sea sand was used to build the house, but at present it is only a sampling test and cannot be determined. The sea sand has not been desalinated and the cost is low, but its use will reduce the building life. In 2011, buildings such as the Bihai Resort in Sha Tau Kok in Shenzhen became dangerous buildings more than 20 years after they were completed due to the use of sea sand. Subsequently, national and local governments issued documents to strengthen supervision. The risk of sea sand house has aroused concern, and the owners hope that the relevant departments will thoroughly investigate the problem to ensure the safety of the building. At present, the relevant testing and rectification work is in progress, and the owners are full of expectations for the results.
