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.

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 toView port mapping information again:父母离奇失踪之后，12岁女孩米雅被安置在一所寄宿学校里。游戏设计师爸爸给米雅留下一本神秘大书，米雅可以通过正确的密码，从现实穿越到书里的精灵王国中去。在精灵王国里，米雅和精灵王子阿莫、精灵战士小优成为了好朋友，并一起保卫王国和精灵们，用团结、智慧和勇气，一次次打败女魔头潘西亚的阴谋诡计。精灵王国有奇异的花草，梦幻般的景色，还有可爱的独角兽。寄宿学校的几个女孩经常欺负米雅，但每当米雅从精灵王国回到现实生活后，她的心灵便得到更多成长，鼓励她用强大乐观的心去面对生活中遭遇的困难。这是一部让女孩学会勇气、智慧和心灵美的片子。Apple的流媒体平台AppleTV+旗下自制剧——太空科幻剧《为了全人类》(For All Mankind)发布预告，这是AppleTV+旗下首部曝光预告的剧集。 该剧由乔尔·金纳曼、莎拉·琼斯(《诅咒》)主演，讲述美国在太空登月竞争中输给了苏联，NASA宇航员们要向火星等更远的地方探索的故事。剧集主创为《太空堡垒卡拉狄加》的幻想剧大手罗纳德·D·摩尔，《冰血暴》制片人马特·沃伯特&本·纳蒂维参与创作。共10集，AppleTV+将在今年秋天上线，具体时间未定。爱情开始的时候，我们往往都不知道是爱情，两个都曾在爱情中受过伤，不相信爱情的人，开始一步一步相识、相知、相爱，有过怀疑和波澜，也有过误会和遭遇人生的低谷，但两人在相爱的过程中，愈发感受到对方才是那个能够托付余生的那个人。偏小葱行事有度，举止大方，由不得人不夸赞。她也没有反抗，反而微笑轻蹙黛眉，似乎被他捏得很痛。
