道路臨時圍擋臨時磚砌(牆)裂隙，坍塌現象屢見不鮮，特別是沿街，人行道一側的現象圍牆倒塌，傷及行人的現象時有發生，有的人員受傷。造成這一現象的原因主要有以下幾點。

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.

有些施工單位認為施工現場的牆屬於臨時性，產生臨時想法，所以在施工中沒有引起重視，不按規範要求去施工；其次是為了節約材料，雖然該牆采用粘土砌築，因此工程竣工後，拆掉圍牆磚進行二次利用，但這種做法勢必導致圍牆本身強度過低，穩定性差；三是在林帶和綠化植被邊砌築，在施工過程中不采取預防措施，因常澆林帶及綠化微噴等，導致圍牆基礎不斷下陷，牆皮脫落，牆體傾斜，四是施工現場圍擋一麵大量堆土，堆放砂石料或其他建築材料，造成牆側壓增大，造成牆身坍塌。

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.

針對以上問題，圍擋施工廠家認為，除了臨時性的施工理念外，施工現場的圍護牆，應根據所處環境地質條件的不同及工程周期的長短，分別采取相應的技術措施。下麵幾種較好的施工方法，僅供參考。

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，當原地表麵砌築牆時，基坑挖深不得小於400mm，施工次序為：先用M5水泥砂漿砌二層500寬磚基礎收台砌一層370砌築500高的240寬實心磚砌築M1粘土砌築牆，並以M5水泥砂漿砌築。

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，在鬆軟的地麵，砌築圍牆時，基礎開挖深度不得少於500mm，施工順序為：基槽底部打夯M5水泥砂漿砌築四層磚砌牆時，基礎開挖不得少於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，在設置林帶邊和植被邊砌牆時，要考慮到林帶澆水和綠化微噴的影響，基礎深度不小於600mm，施工次序為：先澆注500寬200mm厚C10混凝土M5水泥砂漿砌築100mm高的240實心牆M1粘土砌築牆。磚石砌好*靠近植被邊的邊牆和牆邊，立即用M5防水砂漿抹平。

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，砌牆時，磚與磚之間的間距應按規範規定設置，一般為3~3，6m；砌築空鬥牆時，必須按“五鬥一眠”砌築，以確保圍牆整體穩定。此外，還應注意，磚牆邊不能堆土，堆放砂石料或其它建築材料。

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.
