Description
Technical Field
The invention belongs to the field of earthquake simulation, and particularly relates to an earthquake simulation device for a fire fighting pipeline system.
Background
According to statistics, about more than 500 million earthquakes occur on the earth every year, and about twenty earthquakes which can really cause serious harm to human beings occur. The disasters caused by earthquakes are mainly divided into direct disasters and secondary disasters, the direct disasters are primary phenomena of earthquakes, such as earthquake fault dislocation, and ground vibration caused by earthquake waves, and the caused disasters mainly include: destruction of the ground, destruction of buildings and structures, destruction of natural objects such as mountains, and the like; secondary disasters are caused by direct disasters, mainly: fire, flood, toxic gas leakage, plague, etc. The loss caused by primary disasters in earthquake disasters is 31 percent, and the loss caused by secondary disasters reaches 44 percent.
Although various countries including the united states have made much work on earthquake simulation of building bodies from the beginning of the 20 th century, and related designs are incorporated into respective building design specifications, damage to electromechanical systems or pipeline systems caused by building shaking is very likely to cause secondary disasters such as fire, gas or toxic gas leakage, explosion and the like. Especially, in a fire-fighting pipeline system, when a fire disaster is caused by an earthquake, if the fire-fighting pipeline system is damaged, a large amount of fire-fighting water or gas extinguishing agent cannot play a role in reducing the fire disaster, and secondary disasters such as large amount of water leakage and high-pressure gas explosion can be caused to cause secondary damage. At present, although a plurality of earthquake simulation devices related to the building body are designed and researched in China for improving the design calculation of the structure of the building body, no relevant research is carried out on a fire fighting pipeline system for avoiding the damage caused by the earthquake.
