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三人遂越墙而出。莫菲因为暗恋校草任浩，与转校生林书瑤产生误会，为保住自己在任浩心中的位置，计划把林书瑤打造成不良少女，并与校外街霸团伙“黑天使”产生激烈矛盾，莫菲与林书瑤在相处过程中，逐渐发现彼此身上优点，并忽略了任浩的存在。关键时刻，莫菲为了友情挺身而出，为搭救林书瑤铤而走险。初夏带郭佑拜访勺子叔，勺子叔烧制的菜跟郭佑你奶做的菜味道几乎一样，在郭佑的帮助下两位老人家终于重逢。然而好景不长，奶奶的病终究是回天乏术，患上数字过敏症的阿J也无法挽回。绝望的郭佑打晕阿J后离去。悔恨交加的阿J为了拯救40亿人的性命，决定与Satan比赛谁先破解蚂蚁金服的加密算法，可此时的阿J连数学题都做不了，他能成功吗？Stimulate1895年，一对男女神童降世。两个孩子在同一时辰出生在上海西城某家医院，他们的母亲在产后离开了人间。皇太后因得知天命神童能解救天下贫苦的百姓，便下令在他们出世后立即除掉。尚蔲为了保护天命神童的安全，安排法国人马丁将他们带去法国，并将他们抚养长大。皇太后又派忠臣普顿前往法国追杀这对神童，因这对神童相握手时，会产生无穷的魔力，双方于是展开了激烈的斗争，天命神童战胜了邪恶势力并最终返回到中国；通过更换父亲的碑文，救活了他们自己的父亲。随后天命神童便丧失了魔力成为了两名普通的孩子，并开始了新的生活。Set up a solution
