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嫡女元倾澄被未婚夫程文泰与表妹元衣瑶联手杀害，幸得古若尘出手相助，换脸之后，以礼仪老师的身份重返元府，开启复仇之路，在陷害中力挽狂澜，在刺杀中以弱胜强，但最终双拳难敌四手，而这时古若尘的真实身份出现，他竟然是当朝……否则岂非要寒了功臣之心，而且同为越王手下，难免会伤了和气与情分。最让他们没有想到的是，最后一道屏障坚固的咸、阳城，子婴竟然没有做任何抵抗。　　在「50」重案组的帮助下，McGarrett发誓要了结父亲遇害的案子，让父亲得到安息。与此同时，他也将带领自己的战友扫清这座美丽岛屿上的一切邪恶，让夏威夷－－美国的第「50」个州－－永远是人间天堂。What you see today is that I am no longer the same as I was three years ago when I was only Nuo Nuo and was jittery.
