Construction safety should not be empty talk.

Construction safety should not be empty talk, as follows:

On July 23rd, the top of the gymnasium of No.34 Middle School in Qiqihar City, Heilongjiang Province collapsed, causing 1 1 deaths. At present, the public security organs have filed a case for investigation against the relevant responsible persons of the construction unit of the teaching complex, and taken criminal compulsory measures according to law. According to Xinhua News Agency, the Heilongjiang provincial government has set up a joint investigation team to conduct a comprehensive and in-depth investigation into the accident.

The school building collapsed, and more than ten teachers and students were trapped in it. 1 1 lives died innocently, and the building collapse accident happened again, which made people feel worried and even more indignant. Why does the roof of a good gymnasium collapse?

There are three problems in this collapse accident that need to be clarified urgently: First, whether the construction party has illegal construction and illegal storage of building materials. The second is whether there are quality problems in the gymnasium building itself. Third, whether there is supervision dereliction of duty in schools and project-related responsible units and departments.

The preliminary investigation results of the cause of the accident released by Qiqihar press conference on the evening of 24th showed that the main cause of the accident was that the construction unit illegally piled perlite on the roof of the gymnasium during the construction of the teaching complex building adjacent to the gymnasium. Under the influence of rainfall, perlite is soaked in water to gain weight, which leads to the increase of roof load and collapse.

Perlite is a common building external thermal insulation material in the north, which has strong water absorption and weight gain characteristics, so it is often necessary to add waterproof coating to the outer layer in building construction. According to the relevant provisions of the "Regulations on the Administration of Work Safety in Construction Projects", the construction unit should pay attention to the adjacent buildings, structures and underground pipelines that may be damaged due to construction projects;

Special protective measures should be taken. However, such a large number of building materials are piled above the old gymnasium with a history of more than 20 years without any protective measures, and the danger is self-evident. Before construction, do the constructors understand the water absorption and weight gain characteristics of perlite? Has the bearing capacity of the gymnasium roof been evaluated?

Are there any preventive measures against the potential risks caused by local rainfall? If it is found that the relevant responsible person violates the relevant safety management regulations in production and operation, or knows that there is no safety guarantee, or even finds signs of accidents, he still violates the rules and takes risks, which may be suspected of committing a crime.
