Low-rise buildings are no longer suitable for the living needs of the broad masses of the people, and the advantages of high-rise buildings are gradually revealed. Due to the complicated accommodation structure of high-rise buildings, it is easy to cause fire hazard. Therefore, in the daily life process, how to safely set fire hydrants is an extremely important practical topic. As the geographical location and building style of each high-rise building will change according to the actual situation, this also puts forward new development requirements for fire hydrant system design. Based on the actual process of fire hydrant system work in high-rise buildings, this paper will continuously find out and solve the actual problems in the process of fire fighting, analyze and solve the problems in depth, and at the same time, improve the fire safety awareness of the masses. Ensure the safety of the actual accommodation of high-rise buildings, thus laying a solid foundation for the safety of daily life of the residents.展开更多
