A, accident after 8 am on September 10, 20, 2011, in xi 'an not ended drum xuan building project construction site, by scaffolding frame body overall collapse suddenly, that is the east building facade on the overall lift scaffolding frame and metope of furring brick construction and clean 12 workers, since the 19th floor, falling, killing 10 people, 1 person seriously injured, one minor injuries (
On-site killed seven people, by the hospital to rescue invalid death 3 people)
, a direct economic loss of about 8. 9 million yuan.
On the afternoon of September 9, 2011, shaanxi construction group construction engineering co. , LTD. 11 KaiXuan collapse case 149 building project department production Du Mou arranged outside the frame, head of the led monitor Liang Mou scaffolder the overall ascension of scaffolding from 20 to 16 layers.
On September 10, 5 PM in the morning, eight outer wall decorate personnel at KaiXuan 20 floors high building scaffolding to start cleaning and blunt;
7 when 20 points, an outer layer monitor Liang Mou lead eight scaffolder staff began to improve scaffolding down the whole frame work, at the same time, the frame body and above eight workers in the outside walls cleaning, and cleaning personnel are concentrated in the east building of the frame body.
At 8 around 20 points, adhesive lifting scaffolding on the south, a total of four seats, length of about 22 m, height of 14 m lifting frame scaffold overall collapse, causing 12 workers (
Metope brick jointing workers 6 people, 2 people install drain pipe workers, frame body frame 4 workers)
Along with the frame body to fall to the ground outside.
2, 1, accident cause analysis directly recognized by investigation and analysis, is the direct cause of the accident: scaffolding elevator operator in not good hanging electric hoist hook and pull out on the rack body under the condition of construction personnel violate compasses to dismantle positioning bearing component, violations caused by scaffolding down aircraft operations.
2, indirect accident reason (
Shaanxi some construction labor services limited liability company with no quality violations contracting contract KaiXuan building construction and organization construction, the lack of strict and effective management on construction site, is the main cause of the accident.
2, shaanxi construction group construction engineering co. , LTD. 11, no construction general contracting unit security duties according to law, to subcontracting to units without professional qualifications, unified supervision on construction site, check and acceptance, coordination does not reach the designated position, is the important reason for the accident.
3, to KaiXuan building exterior wall decoration and scaffolding lifting operations such as greater danger engineering and technology, safety supervision does not reach the designated position, is the main cause of the accident.
Three, revelation 1, to further establish and improve the safety management system, with emphasis on the safe production responsibility system, strengthen the construction site and dynamic management of high risk operation, the system of construction project department leadership shift and line supervisors job security responsibility to implement.
Must strengthen the construction general contractor in engineering construction and comprehensive, whole process management of safety in production, strict procedures, strictly controlled.
2, according to the procedure construction, is to ensure that the basic conditions of construction safety.
The accident is because the scaffolding elevator operator in not good hanging electric hoist hook and pull out on the rack body under the condition of construction personnel violate compasses to dismantle positioning bearing component, violations caused by scaffolding down aircraft operations.
3, different groups in the same site operation, when different, relevant personnel to do a good job, coordination, management, supervision and guidance of blind you to do your, I dry my, is bound to happen some accident can be expected, but unfortunately, the scene of the accident management, homework personnel on the scene no hazard identification, no forecast possible consequences, the illegal operation, eventually led to the accident.
