It is convenient for fighting and evacuation, and a circular fire lane should be set up. 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这些人见张杨之妻曹氏病着。上古禁決，生死爭奪競存亡。先德集团的大老板林德诚因心脏病并发多种病症，眼看就要不行了，他把妻子秦淑贞唤到病床前，说出了一桩在心底埋藏多年的秘密。原来，二十年前，林德诚随贸易代表团赴香港，恰遇大学时的恋人、现定居台北的田越，久别重逢，别有一番滋味，两人在酒店客房里发生了一夜情。林德诚没有想到，这一夜情竟产生了“遗留问题”。田越返回台北后发现自己有了身孕，她犹豫再三，没有打掉孩子，毅然生了下来，取名“林小凡”。田越把婴儿照片寄给远在上海的林德诚，告之将独自抚养女儿。此后一隔就是十来年，双方皆无音信。现在，林德诚眼看自己已经走到了生命的尽头，他提出想见见这个台北女儿。妻子秦淑贞如闻霹雳，万万没有想到，丈夫竟有一个私生女，她失声痛哭秦朝末年，苛捐杂税重如山，民不聊生。富家千金吕雉虽为女儿身，却胸怀大志，女扮男装外出寻找有志之士。她发现了时任泗水亭长刘邦宅心仁厚，对他渐渐生出好感。项羽密谋起义，为了招揽黥面贼英布，单枪匹马闯入秦军军中将英布的仇人将领赵常斩杀，终于将英布收到帐下。刘邦发现了项羽的秘密。项羽本来想杀他灭口，但刘邦却对他表现得十分敬畏，哭诉了暴秦令人民生活凄苦，因此愿为他效力推翻暴君。于是项羽被感动了，决定招揽他，两人更以兄弟相称。随后，吕雉主动嫁给了刘邦，她知道自己将会辅助刘邦成就大业。秦始皇病逝，赵高扶立秦二世，秦二世荒淫无度，更引得天下大乱，群雄并起。项羽时势造英雄，终于揭竿起义了！
