Building demolition is a high-frequency site for excavator application. Strong excavators have strong breaking force, which is unprecedented in front of buildings. However, due to its own characteristics, building demolition often causes casualties. Now, there is the long arm excavator. The long arm excavator increases the arm length on the basis of the conventional excavator, thereby increasing the scope of construction. At the same time, the lengthening arm is divided into two-segment lengthening arm and three-segment lengthening arm. The lengthening arm of two-stage excavator is mainly suitable for earthwork foundation and deep cutting excavation, River dredging, and the lengthening arm of three-stage excavator is mainly suitable for the disassembly of high-rise buildings and other projects. According to leverage principle and mechanics principle, the force of the extended arm excavator is less than that of the original excavator, and the construction should be avoided as far as possible. Here are some tips for long arm excavators to demolish buildings.
1. The bottom needs to be padded with some fillers, which can be some mud or industrial waste, not only to enhance the stability of the operation of the long arm excavator, but also to enable the excavator to lift the impact hammer to get the roof.
2. When the excavator opens the filler, it will be stabilized first, and there will be enough turning space.
3. Use the hammer to hit the wall in the vertical wall (about 1 meter from the top), open a hole in the wall, push the debris in, don't let it fall and hit yourself.
4. To enlarge the hole, do not move the beams and columns. When the long arm excavator opens the brick wall, it hits the pillars, so that the beams on it can't support and fall into it, so as to guarantee itself.
In the operation, there are also matters needing attention, that is, can not be broken in water or mud. If the very hard object is broken, it can be broken from the edge, there is a certain degree of skill, such as from the edge to make the work of breaking, which will be much more convenient. But it also needs attention. Do not repeatedly knock in one place, not knocked out, it means that the very internal structure is very hard, in general, the same place on the best knock not more than a minute, so as to avoid burning or overheating of the drill rod.
If the heavy objects need to be pushed in the demolition, then don't use the crushing hammer. If the heavy objects are pushed, the crushing hammer will also be damaged, which will lead to overturning seriously.
