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"Well, then you go on." I said, after this inquiry, I confirmed that Liu Guangyuan's "dog" and Qi Shicheng's "dog" are completely different. The latter means only a description of behavior, while the former means that this is an explanation of the nature and type of the creature. I also understood at that time that this should be another brand-new "living biological weapon" of the Vietnamese army different from the humanoid monster.In the "Parameters" tab of the "Block Writing Palette", click "Flip Parameters" again, AutoCAD? The command window at the bottom prompts "Specify parameter position or [name (N)/label (L)/description (D)/palette (P)]", captures and clicks on the corner below the triangle on the graphic; The command window then prompts "Specify the endpoint of the projection line" and drags the mouse vertically for a certain distance before clicking the mouse. The command window prompts "Specify Tag Position" and clicks again nearby.该剧是一部讲述犯罪小说家妻子和离婚律师丈夫之间的故事的喜剧悬疑惊悚片，讲述了怀着负罪感做坏事的大人的故事。《可可可心一家人2》是一部以当代中国家庭生活为背景、展现现实生活的系列家庭幽默动画剧。这是一部关注生活、关注家庭、关注儿童成长的动画新作。本片讲述了主人公可可、可心这对既对立又结盟的龙凤胎所在的一个普通家庭、普通的居民小区和普通幼儿园里所发生的各种逸闻趣事，由此折射出了诸如情感、环保、科技、教育、时尚、宠物、人与人之间关系等一系列新世纪下的社会话题。 而商海棠的初恋情人马静安更遭遇了家破人亡的惨痛，在恋人和亲人相继离去的双重打击之下，他落草为寇，靠着过人的智慧和毒辣，成为独霸一方的匪首，一心不择手段想搞垮鲍家，使商海棠重回自己怀抱……讲述2015年那场震惊世界的巴黎恐袭的纪录片。从国家领导人，到消防员，到幸存者、目击证人，各个经历者平静而真实地讲述那一晚发生的事。
