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何坤似笑非笑，扬鞭一直地上几个莽汉：哦？可受伤的是他们。ラプチェアー 南果歩 石橋 保在春天后一百天, 一百万卢旺达难民在massacred 遇到由他 们的头领Hutu 带领一群士兵,并遭到屠杀,使一个非洲小国瞬间变成地狱。野 蛮是在想像力之外。联合国维和士兵是在那里观看。观看但不行动。一个英国的教士和他的年轻随从目睹这一幕，一时间他们的信念, 他们的勇气和心理极限受到极大的冲击, 最后, 他们被迫做出选择，要么留下来要么与难民一起跑。According to Mei Xiangrong, Pacific Century's chief tourism consultant, the "Charm Card" program is mainly embodied in three aspects. The first is the Brand City Plan, "Charming China City" and the City Alliance have opened up the brand promotion of the city. CCTV has provided a "media + industry" urban development platform, while "Charming Card" has inserted the wings of the Internet into the development of the cultural and tourism industry. The second is the brand scenic spot plan. We hope to directly connect the scenic spots of the city brand with the "Charm Card" on the basis of the platform of "Charm Card". The third is the brand establishment plan of Charming China City. In the future, we can rely on the "Charming Card" to let the city's characteristic agricultural products really come to the city and go to the dining table.State mode: Pay attention to encapsulating state-related behaviors, support state changes, and change its behavior when its internal state changes by encapsulating object state.First of all, actionMasked==MotionEvent.ACTION_DOWN in if is definitely not valid. Look at mFirstTouchTarget! = null, if mFirstTouchTarget is not empty, then the child view consumes the down event and will execute to intercepted=onInterceptTouchEvent (ev); This line of code. If mFirstTouchTarget is empty, it means that the sub-View has not consumed the down event, and directly else has intercepted=true; Interception incident. Then look at the default log:
