Cause analysis

After investigation, Yuejin Printing and Dyeing failed to follow the requirements of the construction design drawings, took the initiative to change the design structure of the sewage pool during construction, and violated the process design requirements by long-term use of aluminum trichloride solution assewage Treatment chemicals cause a large amount of corrosion and breakage of the steel bars in the concrete beams and concrete walls of the sewage pool. The tensile load-bearing capacity of the beams and the bending load-bearing capacity of the walls exceed the limit state of the load-bearing capacity of the beams and walls. Due to the structural The collapse of the pool caused by local damage is the direct cause of the accident.

The accident investigation team found that the failure of Yuejin Printing and Dyeing’s main responsibility for safety production, irregular construction management of Hengxing, and Shengli’s environmental protection illegal design were indirect causes of the accident. Specifically:

The process design was changed without authorization to use aluminum trichloride solution as a sewage treatment agent. Especially after the company failed to pay enough attention and strengthen production safety work after a fatal accident occurred on March 9, 2021, safety awareness was extremely weak.

2. Zhejiang Hengxing Construction Co., Ltd. The internal management is chaotic, the project manager does not have a construction engineer professional qualification certificate, and the construction is not carried out in accordance with national standards. The constructionquality does not meet the relevant national construction engineering safety standards, and construction changes are not formally designed. .

3. Shaoxing County Shengli Environmental Protection Engineering Equipment Factory. Without formal design certification, the process design was changed according to Yuejin Printing and Dyeing’s requirements, process design drawings were issued, and the height of the pool was increased.
