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 toAfter installation, there will be two jres, one inside the jdk and the other outside the jdk.该作根据畅销小说改编，以位于东京新宿歌舞伎町的都立高中为舞台。龙星凉此次饰演的是不知道“水商”是风俗行业，而在该学校担任社会科的教师，却被学生们卷入了各种纠纷……通过不为人知的风俗业展现浓浓人情味是本剧的一大看点。                        咱们绍兴商界，说是彭老官人统领大局，可大家谁都清楚，是你杨长帆把大家聚一起的。《基本演绎法》正式续订第6季。1943年，特种兵部队奉命深入敌后摧毁日寇大规模杀伤性武器，却遭日寇设计而全军覆没，队长尤龙的遗孀周至柔的小妹周志卿，奉国民党军统高层命令查清此事。调查过程中，周志卿身陷险境，正巧被我地下党人赵凯所救，自此一见钟情。两人通力合作，经历重重险境。周至柔是国民党特种部队“猛龙”大队大队长的妻子，中共高级特工，在“猛龙”大队被日本间谍告密而全军覆没后，她同时执行查处奸细并摧毁日寇的任务。当他们终于查出了真相，并摧毁了日寇的大规模杀伤性武器时，更为严峻的考验接踵而至，日寇的惊天阴谋渐渐浮出水面，而最危险的日谍“枭”仍然潜伏在他们身边……
