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上个世纪五十年代末期从海外归国，到了一所名叫月亮湾的乡村小学任教。走过了大跃进、文革、新时期、新世纪等不同的历史时期，经历了刻骨铭心的初恋，到结婚生子，直到成为一名白发苍苍的老头……和越国联合？共同对付汉国？范增似乎是自言自语，但是听到项羽的提议之后，就开始陷入沉思。There are two examinations each year in: April and October, before this to the local self-examination office registration (entrusted by the state), for admission ticket, buy books (Wen Kao only takes an examination of pedagogy and psychology), after the examination, you will get the interview of the local education bureau, after the interview, you can receive the qualification certificate and be qualified to be a teacher.再说济世堂这边，等人都走后，方虎带着泥鳅进去找小葱和秦淼。
