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是首部以人类学角度呈现中国长角苗族习俗习惯的故事片，讲述的是一个古老而神秘的寨子里发生的故事。这个在世界上仅存5000人的族群，未来如何？他们要怎样面对外界的文化冲突？人性在长期恶劣生存环境中，是如何形成的自我保护意识？需要怎样的族群认同和取暖方式，才可以穿过千年历史沿革，走到我们跟前。《落绕》带你走近她，并了解更多不为人知的人类秘密……这是一部在北美，以及多个电影节上获奖影片，讲述的是亚洲中国古老少数民族的故事。Netflix直接预订Veena Sud负责编剧﹑Gavin O’Connor执导的诗选剧《七秒 Seven Seconds》，定于美国时间2月23日上线，首季10集的《七秒》用了美国时下热门题材，讲述在泽西市因为一个黑人少年受到警察的严重伤害而死，因而黑人市民与白人警察 关系十分紧张。Clare-Hope Ashitey饰演K.J.
