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 toHuang Jinbo and Liu Chengjian, who were under covert supervision, also joined the siege.5 No sign, no light, no police intersection, according to the order of let the right-let the left turn-let the straight ahead.李敬文感觉那架势就跟他爹绞麻袋似的。ABC喜剧《喜新不厌旧 Black-Ish》在五月前获预订座落在Freeform的衍生剧，现改名为《成长不容易 grown-ish》（前名《college-ish》），首季为13集，预定在明年1月3日播出。《成长不容易》讲述Zoey在离开家人来到大学后，很快发现这里的生活不能事事如意。母剧演员Deon Cole会在衍生剧继续饰演Charlie，他在大学兼职当市场学教授。Emily Arlook饰演南加州大学新生Miriam，「万事通」的她对人十分坦率，该角在母剧中原本由Mallory Sparks饰演。Chris Parnell饰演南加州大学的事务主任﹑Trevor Jackson饰演一个具有社会意识的大二学生，他们已在后门试映集出场。哼，怕什么，有圣旨在，就算抄错了，横竖要上缴国库，他不过略分一小部分罢了，谁又知道。　　宁城公安大学即将毕业的古岱刚到刑警队实习，就被卷入一场以“游戏”为名的系列作家绑架案——八名悬疑小说家一夜之间被绑销声匿迹。古岱以为自己推理出幕后主办者时，所有线索却都抛向他，他成为这起绑架案的第一嫌疑人。经过缜密的侦查，刑警大队副大队长王梓越发觉得这起绑架事件另有隐情。随着案件的深入，警方和作为游戏参赛者的古岱也逐渐有了头绪，零散的线索渐渐清晰，同为被绑八名作家中一员的真正绑架案元凶浮出水面。此案因古岱而起，也因古岱而终。古岱凭借自己层层推理，配合警方迅速破案。过程中，他也成长为一名合格的人民警察。
