Yesterday, a huge tower crane fell to the ground at the parking lot site under construction on the 12 line. Morning Post reporter Yang Shenlai
The pouring platform of the ground maintenance warehouse of Jinqiao parking lot on 12 line collapsed the night before, killing 5 people and injuring 17 people. At that time, the maintenance warehouse was pouring concrete. According to the introduction of the Municipal Health Bureau, the seriously injured were 1 person, and the vital signs of the other wounded were stable. Another builder fainted due to emotional stress and was taken to hospital for treatment.
The safety supervision department said that the search and rescue work ended around 1 yesterday morning and the cause of the accident is still under investigation.
Shen Jun, vice mayor, presided over a special meeting yesterday afternoon in response to the first casualty accident caused by the collapse of the project under construction on 12 line, demanding that people-oriented efforts be made to treat the wounded, do a good job in the aftermath, and investigate the cause of the accident according to law.
The roof collapsed first.
The metro maintenance depot is located near Jinsui Road, Jinhai Road, Pudong, with a length of about 120m, a width of about 60m and a height of about 10m. According to an on-site reinforcement worker, the maintenance garage is divided into four parts, which are built from south to north in turn, and about a quarter of the roof near the north collapses.
Yesterday, on the construction site, a cordon surrounded the incident. The bamboo on the scaffold is inclined from all sides to the middle, and many cement columns 1 m square stand on the ground. Through the lower scaffolding, you can see some concrete blocks and bamboo on the ground of the maintenance station. There is a concrete pump truck parked next to the maintenance garage, and its pump wall is pressed on the scaffold by the oblique yellow tower crane arm. The yellow tower crane arm bumped into the mud, and less than 3 meters away from it, it was the blue shed of the site material keeper and his wife.
The nurse recalled that his wife was already sleeping in the shed, and he was watching by the concrete pump truck. First, he heard something break. When he looked up, all the bamboo on the scaffold fell in the middle. Next, he heard a bang, the roof collapsed, the tower crane arm hit his shed, and then there was no sound. It all happened in a few seconds, the nurse said. At that time, he was too scared to walk, and he couldn't shout if he wanted to call his wife for her life.
Cai Jinhua, a worker who escaped from the accident, recalled that at that time, machines such as pump trucks roared, and he could not hear the precursor sound of roof collapse at all. He felt suddenly weightless and fell down, surrounded by steel plates and wet concrete. I didn't save myself until the rescuers arrived.
Catch up on work that night
The reporter learned that the winning bidder for garage construction is Shanghai No.2 Construction Co., Ltd.
Outside the warning line at the scene of the accident, the construction workers are still discussing. The day before yesterday was originally the final delivery date of the maintenance depot, and concrete pouring began that afternoon, which is expected to be completed in the evening. * * * About 1.800 square meters of concrete, and there were more than 200 square meters left on the pouring surface at the time of the incident. In order to deliver the project on time, three concrete pump trucks operate at the same time, and the tower crane helps to transport concrete. Before pouring concrete, only 1 or two pump trucks were working.
A steel worker said that near the end of the year, workers need to go home for the New Year, and the handover date is approaching. Recently, the construction site has been rushing to work. It rained and snowed in Shanghai a few days ago. They worked overtime at night and their clothes were soaked.
An escaped bricklayer analyzed that one cubic meter of concrete weighs more than 2 tons, and the weight of the whole roof can be imagined. In addition, the recent low temperature and slow solidification of concrete in Shanghai may be the cause of roof collapse. The tower crane arm was pulled down after the roof collapsed.
After the incident, the city leaders immediately rushed to the scene to direct the rescue. Public security, safety supervision, fire control and other departments in Pudong New Area spared no effort to search and rescue the buried workers. The wounded were then sent to Shuguang Hospital and Gong Li Hospital for treatment, and the search and rescue work ended around 1 yesterday morning.
The accident * * * caused five workers to die, and 17 workers were injured, most of which were fractures, soft tissue injuries and eye burns. Except for 1 patient with severe lumbar fracture, the rest of the wounded were in moderate or mild condition. At present, the vital signs of all the wounded are stable. Among them, 1 minor injuries were discharged yesterday morning. Today, Shuguang Hospital will organize elite soldiers to operate on several fracture patients.
It is understood that another injured family member fainted after arriving at the scene and was also taken to hospital for treatment.
Currently, the cause of the accident is still under investigation.
