With the accelerating pace of urbanization, urban land is increasingly tight, which promotes the construction of high-rise buildings. Many high-rise buildings, due to poor consideration of fire prevention design and other reasons, have many congenital hidden dangers, and fires occur from time to time, causing heavy losses. In order to create convenient conditions for fire fighting and rescue work and ensure the safety of buildings, circular fire lanes should be set up around high-rise buildings. However, regardless of the size of the building, it is indeed difficult to require the circular fire lanes. Lanes can be set up along the two long sides of the building. In order to prevent the collapse of building components in case of fire from affecting the normal operation of the fire lane, the distance between the fire lane and the outer wall should be 5m. There should be no trees, overhead pipelines, etc. that hinder the operation of climbing fire engines between fire lanes and high-rise buildings. If the total length of the building exceeds 220m, a fire lane shall be set up to pass through the building. There is no inner courtyard in the building, there are ring fire lanes around it, and fire engines crossing the building need to be set up. Q: An L-shaped high-rise building has a total length of about 170m, a length of 120m along the street, and a length of 50m along the inner street (residential road). Do you want to set up fire lanes crossing the building? A: The relevant provisions of the "Construction Regulations" and "High Regulations" consider that there is no restriction on the length of the two wings on the premise of meeting the requirements of fire fighting and evacuation. The building only needs to set up a pedestrian passageway connecting the street and the inner courtyard at the part over 80m along the street, and there is no need to set up a fire lane. In the planning of fire lanes, in addition to the relevant provisions of the "Construction Regulations" and "High Regulations", attention should also be paid to月末，夜色沉沉，张家上房门口只挂着一盏灯笼，院子里暗影重重。申道终于明白日本将在2年内毁灭，于是走上了和妖兽战斗的悲惨道路……《我是大侦探》是湖南卫视和芒果TV共同打造的大型情境类益智互动推理秀，由《明星大侦探》原版人马倾情打造，节目将秉承电影级高品质的精良制作水准，以调动“全民动脑”为首要宗旨，再加入极致夸张逗趣的明星角色扮演等综艺元素。一档节目同时融合“综艺感”、“电影感”、“角色扮演”、“演技比拼”、“推理角力”等众多元素，并精心打造超逼真场景，致力于开发最便捷最好玩的互动模式，每期集结6位超强阵容高能玩家，解锁层层悬念，找出关键人物K，引发全民推理热潮。一群人上演了一场啼笑皆非的追逐打斗故事，最后，正义终于战胜了邪恶。It should be noted that: 1.
