Q:What is a door rack for a construction site? How high is it generally?

This depends on the erection of the height of the general 3 steps and within 5-6 yuan a meter, assuming the erection of 4.5 meters high, 22.5-27 yuan a square. This is calculated in accordance with single-layer, the higher the more expensive, 9 meters in 65 yuan or so square. In accordance with the establishment of meters, in accordance with the erection of the volume of the calculation.

Q:What measures can effectively reduce the construction accident rate?

Hefei construction workers training _ fail safe design: in the part of the system, equipment malfunction or damage, can also ensure the safety of safety and technical measures known as fault - Safety Design in a certain period of time (fail-safe). Generally speaking, through careful technical design, the system and equipment are in a low energy state when the fault occurs, thus preventing the unexpected release of energy. For example, a fuse in an electrical system is a typical fault - Safety Design; when the system is overloaded, the fuse is fused and the circuit is disconnected to ensure safety. Although the fail safe design is an effective measure of safe technology, but considering the fail safe design itself may not work due to failure, so the choice of safety technical measures should not give priority to the use of.
