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 toThen start a container based on the v3 version of the image:直觉告诉他，尉缭留在关中的目的不会那么简单……那好，娄便在山yīn等候尉缭先生大驾，这一路上也有劳先生了。刘哥是一个精明干练的中年人，他很肯定的说道。四个女孩Duchess、Sundae、Mimi和ViewViva住在Jam夫人的公寓里，这栋公寓有一个严格的规定，那就是：不允许男孩进入这栋公寓，但是她们的爱情却都发生在这栋公寓里……罗伯特打算在接下最后一份价值200万的合约后洗手不干，他的任务是去杀死一个专门窃取机密的电脑盗贼并取回一份磁碟。而贝米高也同样接受了这一任务。双方在酒店展开了一场竞争。罗伯特抓住了电脑窃贼伊莉，拿到了磁碟。而贝米高则杀死了前来购买磁碟的国际刑警，并进而追踪到伊莉的寓所。
