Tower Crane Emergency Plan
I. Policy and Principles of Emergency Plan
Better adapt to the requirements of the law and economic activities; provide a better and safer environment for the work of the enterprise's employees and the surrounding residents of the construction site; ensure that all kinds of emergency resources are in a good state of readiness; and guide the emergency operations in an orderly manner according to the plan; Prevent the emergency rescue from being delayed due to poor organization of the emergency action or the disorder and confusion of the rescue work on site; effectively avoid or reduce casualties and property losses; help to achieve rapid, orderly and efficient emergency response; fully embodies the "emergency spirit" of emergency rescue. Adhere to the policy of "safety first, prevention first", "prioritize the protection of personnel safety, environmental protection", and implement the principle of "constant preparedness, unified command, efficient coordination, and continuous improvement". The principle.
Two, emergency planning
(a) Project Overview
This project is located in Shenzhen City, Liantang, the west side of the first road, the terrain is low in the north and south of the state of high, the plot of land on the south side of the east and west side of the city has been built in the residential area, the north can be seen in the mountain scenery. No.1 Road extends to Xianhu Botanical Garden. The project includes B1, B2 two tower residential buildings and semi-open underground parking garage. The project ±0.00 corresponds to the absolute elevation of the Yellow Sea Elevation 43.0 m; the building area is 6500 m2 The structure type is frame structure, and the seismic intensity is 6 degrees. It consists of two twelve-story residential buildings, with the garage on the first underground floor and one~twelve-story residential buildings.
(II), emergency plan workflow
According to the characteristics of the project and the actual situation of the construction process, carefully organized the identification and evaluation of hazardous sources and environmental factors, specially formulated for this project in the event of an emergency or an accident emergency measures, to carry out education on emergency response knowledge and emergency response drills, to improve the emergency response capability of the site operators, to reduce the damage caused by the emergencies and adverse environmental impact.
(3) major accidents (hazards) development process and analysis tower crane operation suddenly safety limit device out of control, impact on guardrail and adjacent tower crane or falling objects, or violation of safety regulations for operation, resulting in major accidents (such as tipping, broken arm); operation of electrical equipment failure or serious leakage of the line; other operations may occur in the event of major accidents (fall from height, lifting injuries, electrocution, etc.) The resulting casualties, property damage, and environmental damage.
(D) risk analysis and prevention of emergencies
In order to ensure normal construction, prevention of tower cranes in the use of the process of emergencies as well as some unforeseen, irresistible events, beforehand, there are sufficient technical measures to prepare, the reserve of emergency supplies, to minimize injuries and deaths, national property and economic losses, must be carried out to analyze the risk and take effective Preventive measures.
1, contingencies, emergencies and risk analysis
According to the characteristics of the project, in the identification, analysis and evaluation of the tower crane in the use of risk factors and risk based on the tower crane in the use of the process of determining the major risk factors are tower crane operation in a sudden loss of control of the safety limiting device, the occurrence of the impact of the guardrail and the neighboring cranes or falling objects, or violation of the safety regulations operation, resulting in major accidents (eg. Failure of electrical equipment or serious leakage of electricity in the line during operation. In the site has been taken on the basis of mechanical and electrical management, safety management of a variety of precautions, but also need to develop the tower crane tipping emergency program, as follows: assuming that the tower crane foundation collapse may be tipping; assuming that the tower crane torque limit failure, the crane driver violates the rules of operation of the crane is seriously overloaded lifting, may cause the tower crane tipping.
2, contingencies and risk prevention measures
From the analysis of the above risk situation, if the corresponding effective preventive measures are not taken, not only to the construction of the project has a great impact, but also a threat to the safety of construction workers.
f tower crane operation and use should be in accordance with the following provisions:
① tower crane before the operation, should check the metal structure, connecting bolts and wire rope wear and tear; before power supply, the controller handle should be in the zero position, no-load operation, test the institutions and safety devices and confirm normal.
② tower crane operation is strictly prohibited overloading, diagonal pull and lifting buried in the ground and other unknown weight objects;
③ lifting bulk objects, should be made of special cages or containers, and should be guaranteed that the material will not fall off in the process of lifting. The cage or container should be tested according to twice the load of the permissible carrying capacity before use, and should be inspected regularly during use;
④When lifting long materials such as multiple steel pipes and reinforcement bars, it is necessary to make sure that the slings are securely tied to prevent the slings from slipping and the materials from falling out during the lifting process;
5The distance between any part of the tower crane (including the lifting objects) should not be less than 2m between two or more tower cranes. When the requirements can not be met, measures should be taken to adjust the working height of adjacent tower cranes, add travel limit, slewing limit device, and other measures, and formulate the operating procedures for cross operation;
⑥ cables hanging vertically along the tower should be suspended using a reliable device that is not stretched and abraded by the weight of the cables;
1) the completion of the operation, the lifting arm should be turned to the downwind direction, and should be released to swing Brake, lifting trolley and counterweight should be placed in a non-working state.
g In order to prevent accidents, the tower crane must be installed and dismantled by qualified professional team, the tower crane driver must be licensed, after installation by the Technical Supervision Bureau of Special Equipment Safety Inspection Center or the Construction Management Bureau of the Safety Supervision Station acceptance before being put into use.
h tower crane driver operation, must be strictly in accordance with the operating procedures, are not allowed to work against the rules, the strict implementation of the "ten do not hang", before the operation must have a safety and technical briefing records, and fulfill the signature in the sequel.
(5), laws and regulations
"Construction tower crane safety operation technical regulations", "on the provisions of the administrative responsibility for large-scale safety accidents," Article 7, Article 31; "production safety law" Article 30, Article 68; "construction safety regulations", "safety license regulations".
