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 toAs Zhao Mingkai said, This unknown dog-like creature has teeth similar to those of salmon, Driven by bite force, it can cause horrible damage to skin, Coupled with the special "X" petal-shaped mouth structure, With the same bite, This mouth shape can cover a larger area, Or can bite a larger target, Although this structure may be more difficult to exert biting force than the common upper and lower structure of the mouth, But I don't know what the bite force of this monster dog is, But what is certain is that it is definitely not small. Special mouth shape + sawtooth salmon-like cut teeth, This also explains why this strange dog, which has always been small, can bite nearly two-thirds of the muscles (watermelon size) of an adult male thigh. Even if it is a small watermelon, if you are interested, you can buy one and put it on your thigh to gesticulate to see how much the volume has reached the total thigh muscle) and tear it off.Take the website of "Learning Power" as an example, the "Red China" section is convenient for everyone to learn about Party history. It has eternal monuments, classic works, red memories, party history study and other columns. The column "Forever Monument" introduces the stories of heroes such as Li Dazhao, Cai Hesen, Liu Hulan, Ma Benzhai, Qiu Shaoyun and Deng Enming. The column "Learning Party History" answered the questions of why founding ceremony's salute fired 28 rounds, why the "Rice and Cotton War" took place in the early days of Shanghai's liberation, and why Mao Zedong affirmed Chen Duxiu's achievements at the Seventh National Congress of the Communist Party of China.少女们度过的快乐、热闹的日子!王穷等人正准备走,却见张家人聚在一块,刚认回来的儿子跟老子娘现算账提条件,不然不回家,都惊奇万分,一齐围上来听,连王尚书和冯大人也竖起了耳朵。电视剧《龙飞相公》阵容强大,由饰演过多部脍炙人口古装剧的关礼杰担当男主角龙飞相公,台湾知名演员吴辰君扮演温柔客栈老板娘殷百雁,误认龙飞是杀父凶手,又与孙耀威扮演的龙飞之孙,有一段缠绵悱恻的感情戏。该剧还大胆起用了两位新人,陈彦和谢元真,清纯可人,给人眼前耳目一亮的感觉。总之,不要当面顶撞,好汉不吃眼前亏,顶撞也要看人的。
