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二十世纪七十年代，揭西凤凰山下的凤凰小镇。何三妹与同在毛泽东思想宣传队工作的李大庆日久生情，一次约会，被当场抓“奸”，抓“奸”人正是疯狂追求何三妹的杨豆筋，何三妹被开除宣传队回到河东小学教书，这对于条件艰苦的河东小学来说无疑是一股温暖的春风。然而，李大庆入伍，何三妹的信件被杨豆筋做了手脚，导致何三妹与李大庆感情上的误会，杨豆筋骗取了何三妹的信任，新婚之夜，何三妹发现了杨豆筋的骗局，但木已成舟，从此，苦难和煎熬折磨着何三妹。何三妹面临着爱情的折磨、家庭的苦难，毅然坚持着辅导教育孩子们，培养了一批批国家有用人才。一个偶然的机会，一位记者采访到了何三妹，在人民日报头版发表了《山沟里真正飞出了金凤凰》的感人报到，轰动全国，国家给予了何三妹最高的荣誉“人民的好教师”的称改编自美国同名青春电影。I.
