施工现场围挡技术介绍

一是有的施工单位认为施工现场的围墙属于临时性的,产生临时观念,故在施工时未加以重视,不按照规范要求去施工;其次是为节省材料,围墙采用粘土砌筑,以便工程完工后拆除围墙砖作二次利用,但此做法势必造成围墙自身强度太低,稳定性差;三是在*近林带和绿化植被边的围墙砌筑,施工时未采取防范措施,由于受到林带经常浇水和绿化微喷的影响,造成围墙基础不断下沉,墙皮脱落,乃致墙体倾斜、倒塌;四是施工现场围墙一侧大量堆土、堆放砂石料或其他建筑材料,对围墙产生较大的侧压力,而导致围墙倒塌。
One reason is that some construction units believe that the walls on the construction site are temporary and have a temporary concept, so they do not pay attention to them during construction and do not follow the standard requirements for construction; Secondly, in order to save materials, the wall is built with clay, so that after the completion of the project, the wall bricks can be removed for secondary use. However, this practice will inevitably result in low strength and poor stability of the wall itself; The third is the construction of walls near forest belts and green vegetation, without taking preventive measures during construction. Due to the frequent watering of forest belts and slight spraying of green vegetation, the foundation of the wall continues to sink, the wall peels off, and the wall tilts and collapses; Fourthly, a large amount of soil, sand, stones, or other building materials are piled up on one side of the construction site fence, causing significant lateral pressure on the fence and causing it to collapse.
根据上述问题,笔者认为施工现场的围墙砌筑,除临时观念外,应根据所处的环境地质条件的不同及工程的周期长短,分别采取相应的技术措施进行施工。以下是笔者认为较好的几种施工方法,仅供同行们参考。
Based on the above issues, the author believes that in addition to eliminating temporary concepts, corresponding technical measures should be taken for the construction of the enclosure wall at the construction site according to the different environmental and geological conditions and the length of the project cycle. The following are several construction methods that the author believes are better, for the reference of colleagues only.
1.在原土地面上砌筑围墙时,基础开挖深度应不小于400mm。施工顺序为:先用M5水泥砂浆砌筑两层500宽砖基础 收台砌一层370 砌筑500高的240宽实心砖砌体 M1粘土砂浆砌筑240空斗墙 M5水泥砂浆围墙压顶。
When building a wall on the original soil surface, the excavation depth of the foundation should not be less than 400mm. The construction sequence is as follows: first, use M5 cement mortar to build two layers of 500 wide brick foundation and one layer of 370 brick masonry with 500 high 240 wide solid brick masonry M1 clay mortar to build 240 empty bucket wall M5 cement mortar to top the wall.
2.在松软的地面上,砌筑围墙时,基础开挖深度应不小于500mm。施工顺序为:基槽底部进行打夯 M5水泥砂浆砌筑四层500宽砖基础 收台砌一层370砖 砌筑1000mm高的240实心砖砌体 M1粘土砂浆砌筑240空斗墙 M5水泥砂浆压顶。图略。
2. When building walls on soft ground, the excavation depth of the foundation should not be less than 500mm. The construction sequence is: ramming the bottom of the foundation trench with M5 cement mortar, laying four layers of 500 wide brick foundation, laying one layer of 370 bricks, laying a 1000mm high 240 solid brick masonry with M1 clay mortar, and laying a 240 empty bucket wall with M5 cement mortar for topping. Sketch.
3.在林带边和植被边砌筑围墙时,要考虑林带浇水和绿化微喷的影响,基础深度应不小于600mm。施工顺序为:先浇注500宽200mm厚C10砼 M5水泥砂浆砌筑100mm高的240实心墙 M1粘土砂浆砌筑240空斗墙 M5水泥砂浆压顶,砌筑完毕*近林带和植被一侧的围墙,墙面就立即用M5防水砂浆抹面。
When building walls along forest belts and vegetation, the first consideration should be given to the effects of watering the forest belts and spraying green trees. The foundation depth should not be less than 600mm. The construction sequence is as follows: First, pour 500 wide and 200mm thick C10 concrete M5 cement mortar to build a 100mm high 240 solid wall, M1 clay mortar to build a 240 empty bucket wall, and M5 cement mortar to press the top. After the construction is completed, the wall on the side near the forest belt and vegetation will be immediately plastered with M5 waterproof mortar.
4.围墙砌筑时,砖垛的间距必须按照规范要求设置,一般为3~3.6m设一个砖垛;在砌筑空斗墙时,必须按照“五斗一眠”进行砌筑,以确保围墙整体稳定性。另外一点需要注意的是,砌筑好的围墙一侧严禁堆土、堆放砂石料或其他建筑材料。
4. When constructing the wall, the spacing between brick stacks must be set according to the requirements of the specifications, usually one brick stack is set at 3-3.6m; When building empty bucket walls, it is necessary to follow the principle of "five buckets and one sleep" to ensure the overall stability of the wall. Another point to note is that it is strictly prohibited to pile soil, sand, stones, or other building materials on one side of the built wall.
