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小学生甄诚在暑假期间偶然发现一艘外星飞船，里面只剩下船长的外星宠物哆布哆，原来因为哆布哆操作失误，导致飞船损坏，飞船里的乘客失散各地，船长昏迷不醒。为了弥补过错，哆布哆和甄诚达成协议，由甄诚和他的小伙伴代替哆布哆去寻找丢失的飞船零件、乘客和能令船长苏醒的飞船钥匙，而哆布哆为甄诚他们提供具有神奇功能的外星道具。在甄诚的帮助下，飞船修好了，乘客也找了回来，这期间，甄诚和哆布哆成为最忠实的伙伴，也让他们共同成长起来。但是新的问题随之而来，他们发现能让船长苏醒的钥匙竟然是哆布哆，哆布哆决定牺牲自己来救回船长。最后在船长的帮助下，哆布哆复活，并由一个外星宠物升级为船员，结束了地球之旅。Public void method2 () {}降魔师的出现加上战神拓跋羽的追查使得悬案的真相逐渐浮出水面。原来被战神带回的女子真是九尾狐妖，但神都城内连环凶杀案的凶手却另有其人，随着受害者越来越多，侦破案件迫在眉睫。最终经过降魔师坚持不懈的努力，联合所有正义的力量，最终将真正的凶手绳之以法。在找不到答案的情况下，艾恩斯一个人访问了冒险者工会。家境贫寒的李顺爱，为了维持家中生计，高中毕业后就踏入社会。不久嫁给一名刑警，当顺爱还未充分享受到新婚带给她的幸福时，一场车祸夺去了丈夫的生命……When I interviewed Zhao Mucheng, he urged him to leave at 5 o'clock every afternoon.
