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作为天启粉丝大本营，启明上更是沸腾起来。网络电视剧「Matching！少年射箭部」是部青春、搞笑、成长电视剧，讲述了网漫作家志愿生的女主人公，为了寻找素材，潜入花美男射箭部后所发生的左冲右撞的故事。那位越国的依兰夫人夫人比西楚国的虞姬夫人更加的美艳动人。项羽则是眉间一冷，目中寒光陡生，质问道：是不是因为你手下那三万人马也是秦国人？尹旭如同坠入冰窖，这才想起项羽刚才所说的是——所有秦国降卒，也包括自己麾下，苏角那三万人马。家事律师markus发现假期艳遇的对象lena怀孕，他以为终于能如愿拥有自己的家室。他决定花多点时间来了解lena,毕竟两人相识的时间不长，然而lena的父亲hartmut对女儿的新男友似乎没什么好感。markus来到鲁尔区营地参加hartmut的50岁生日派对.hartmut竟动员营地所有人来整markus,他与未来的岳父即将展开一场爆笑的大战。"State Pattern Reconstruction"
