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板栗听了怔住，却依旧不能释然。马列文（陈建斌 饰）是一位实体书店的守望者，他的梦想就是开办实体书店，让城市中的人们有可以沉下心来享受阅读乐趣的一方净土，因而不惜牺牲商业利润来守护精神家园。出于责任，他照顾着身患躁郁症的前妻王忆如（刘威葳 饰），而家庭教师简单（梅婷 饰）的出现为他的生活带来一丝慰藉。简单原是一位中学教师，辞去教职来北京与未婚夫冯春生（涂松岩 饰）结婚却惨遭背叛，简单在马列文的提点下勇敢拒绝了委曲求全的婚姻，并和马列文之间产生了莫名的情愫。马列文复杂的家庭关系使得二人虽已心意相通却彼此克制。而此时马列文前妻病愈归来想要复婚。面对责任、爱情以及岌岌可危的事业，马列文没有选择逃避，决定牵起简单的手，共同面对，最终战胜困难，实现了一直守望的梦想，收获成功，感悟幸福其实很简单。Ariyun几人发愁了：就算找到了这地方，他们只有几个人，又能如何？不说这溶洞九曲十八弯，单是洞中好几千敌人就不是他们能抗衡的。25.
