The Correct Method of Mechanical Destruction
✅ The machines must work on a smooth and firm surface and have a suitable balance weight to prevent overturning during work. be replaced. ✅ sufficient water spraying or other preventive measures should be provided to reduce the pollution caused by dust. The limit of the roofs did not cause vibration and disturbance to the neighboring properties and no damage to the underground facilities.
✅ The car cabin must have impact-resistant glass and have sufficient resistance to protect the operator from falling debris.
Pressure Arm Mechanical Method
The push arm method includes the use of machines equipped with push arm accessories to apply horizontal blows and destroy structural members.
The special conditions for push arm destruction are as follows:
1- The push arm must be made of steel or similar materials and have sufficient resistance for construction works. 2- There must be a minimum safe distance equal to half the height of the building member to be destroyed between the machine and the building, to enter The pressure on the building should be maintained. 3- The pressure point should not be lower than two-thirds of the height of the member. 4- The use of pressure arm method should be limited to buildings with a height of less than 15 meters.
Mechanical Method of Forecasting Forecast
Mechanical method of wire rope stretching
Mechanical demolition by wire rope tension generally involves the use of a moving machine equipped with a strong steel cable to pull down structural members.
Specific conditions for using the wire rope tension method are as follows. is:
1- A safe distance of 1.5 times the height of the destroyed members must be maintained between the machine and the building during the operation. move parallel to the tension line.
3- The wire rope or chain must be made of steel with tensile stress more than 4 times the theoretical force required for tensioning.
4- Any sharp edge that The wire rope must be wrapped around it, it must be covered to minimize the possibility of the rope being cut or worn during the tension. It should be done in a controlled manner. 6- The method of pulling by wire rope should be limited to buildings with a height of less than 15 meters.
