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~--~接到周大和陆明的奏报，说是东瓯姒摇送上降表，要直接投降。洪定威本来是香港HKFIRM 律师楼 老板之一兼执业律师，但却因一次上庭时冲动之下冒犯了法官而被吊销了律师执照。屋漏偏逢连夜雨，合伙人这是卷款潜逃，一时令到 HKFIRM 恶名昭著，稍有经验、名声的律师都不敢和HKFIRM扯上关系，怕玷污了自己的名声。葫芦气得逼上前一步，一把揪住老鳖胸前衣裳，瞪眼道：你再瞎说。但是一旦出兵江北，形势就完全变了。　　The 4 different poles — Nick (Pon), Wan (Mo), Beam (Patricia), and Wayu (Godt) — continuously circle around each other, repeatedly clashing and burning in the fire of the collision.
