道路临时围挡临时砖砌(墙)裂隙，坍塌现象屡见不鲜，特别是沿街，人行道一侧的现象围墙倒塌，伤及行人的现象时有发生，有的人员受伤。造成这一现象的原因主要有以下几点。

Cracks and collapses of temporary brick (wall) of temporary road enclosure are common, especially along the street and on the side of the sidewalk. The wall collapses and hurts pedestrians occasionally, and some people are injured. The main reasons for this phenomenon are as follows.

有些施工单位认为施工现场的墙属于临时性，产生临时想法，所以在施工中没有引起重视，不按规范要求去施工；其次是为了节约材料，虽然该墙采用粘土砌筑，因此工程竣工后，拆掉围墙砖进行二次利用，但这种做法势必导致围墙本身强度过低，稳定性差；三是在林带和绿化植被边砌筑，在施工过程中不采取预防措施，因常浇林带及绿化微喷等，导致围墙基础不断下陷，墙皮脱落，墙体倾斜，四是施工现场围挡一面大量堆土，堆放砂石料或其他建筑材料，造成墙侧压增大，造成墙身坍塌。

Some construction units think that the walls on the construction site are temporary and have temporary ideas, so they do not pay attention to the construction and do not construct according to the specification requirements; Secondly, in order to save materials, although the wall is built with clay, so after the completion of the project, the wall bricks will be removed for secondary use, but this practice will inevitably lead to low strength and poor stability of the wall itself; The third is to build beside the forest belt and green vegetation, and no preventive measures are taken during the construction process. Due to the frequent watering of the forest belt and green micro-spray, the wall foundation is constantly sinking, the wall skin is falling off, and the wall is inclined. The fourth is to pile up a large amount of soil on the side of the construction site enclosure, and pile up sand and gravel or other building materials, resulting in increased wall side pressure and wall collapse.

针对以上问题，围挡施工厂家认为，除了临时性的施工理念外，施工现场的围护墙，应根据所处环境地质条件的不同及工程周期的长短，分别采取相应的技术措施。下面几种较好的施工方法，仅供参考。

In view of the above problems, the enclosure construction manufacturer believes that in addition to the temporary construction concept, the enclosure wall at the construction site should take corresponding technical measures according to the different environmental geological conditions and the length of the project period. The following several better construction methods are for reference only.

1，当原地表面砌筑墙时，基坑挖深不得小于400mm，施工次序为：先用M5水泥砂浆砌二层500宽砖基础收台砌一层370砌筑500高的240宽实心砖砌筑M1粘土砌筑墙，并以M5水泥砂浆砌筑。

1. When the wall is built on the original surface, the excavation depth of the foundation pit shall not be less than 400mm. The construction sequence is as follows: first build two layers of 500 wide brick foundation with M5 cement mortar, and then build a layer of 370 thick 240 wide solid brick masonry wall with 500 high, and then build the M1 clay masonry wall with M5 cement mortar.

2，在松软的地面，砌筑围墙时，基础开挖深度不得少于500mm，施工顺序为：基槽底部打夯M5水泥砂浆砌筑四层砖砌墙时，基础开挖不得少于500mm。

2. When building the wall on the soft ground, the foundation excavation depth shall not be less than 500mm. The construction sequence is: when the bottom of the foundation trench is rammed with M5 cement mortar to build the four-layer brick wall, the foundation excavation shall not be less than 500mm.

3，在设置林带边和植被边砌墙时，要考虑到林带浇水和绿化微喷的影响，基础深度不小于600mm，施工次序为：先浇注500宽200mm厚C10混凝土M5水泥砂浆砌筑100mm高的240实心墙M1粘土砌筑墙。砖石砌好*靠近植被边的边墙和墙边，立即用M5防水砂浆抹平。

3. When setting up the wall beside the forest belt and vegetation, the influence of forest belt watering and greening micro-spray should be considered first. The foundation depth should not be less than 600mm. The construction sequence is: first pour 500 wide and 200 mm thick C10 concrete M5 cement mortar to build a 240 solid wall with a height of 100 mm and M1 clay masonry wall. The side wall and wall edge close to the vegetation shall be paved with M5 waterproof mortar immediately.

4，砌墙时，砖与砖之间的间距应按规范规定设置，一般为3~3，6m；砌筑空斗墙时，必须按“五斗一眠”砌筑，以确保围墙整体稳定。此外，还应注意，砖墙边不能堆土，堆放砂石料或其它建筑材料。

4. When building walls, the spacing between bricks should be set according to the specifications, generally 3~3, 6 m; The empty bucket wall must be built according to "five buckets and one sleep" to ensure the overall stability of the wall. In addition, it should also be noted that soil, sand and stone or other building materials should not be piled near the brick wall.
