道路臨時(shí)圍擋臨時(shí)磚砌(墻)裂隙，坍塌現(xiàn)象屢見不鮮，特別是沿街，人行道一側(cè)的現(xiàn)象圍墻倒塌，傷及行人的現(xiàn)象時(shí)有發(fā)生，有的人員受傷。造成這一現(xiàn)象的原因主要有以下幾點(diǎn)。

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(rèn)為施工現(xiàn)場(chǎng)的墻屬于臨時(shí)性，產(chǎn)生臨時(shí)想法，所以在施工中沒有引起重視，不按規(guī)范要求去施工；其次是為了節(jié)約材料，雖然該墻采用粘土砌筑，因此工程竣工后，拆掉圍墻磚進(jìn)行二次利用，但這種做法勢(shì)必導(dǎo)致圍墻本身強(qiáng)度過低，穩(wěn)定性差；三是在林帶和綠化植被邊砌筑，在施工過程中不采取預(yù)防措施，因常澆林帶及綠化微噴等，導(dǎo)致圍墻基礎(chǔ)不斷下陷，墻皮脫落，墻體傾斜，四是施工現(xiàn)場(chǎng)圍擋一面大量堆土，堆放砂石料或其他建筑材料，造成墻側(cè)壓增大，造成墻身坍塌。

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(duì)以上問題，圍擋施工廠家認(rèn)為，除了臨時(shí)性的施工理念外，施工現(xiàn)場(chǎng)的圍護(hù)墻，應(yīng)根據(jù)所處環(huán)境地質(zhì)條件的不同及工程周期的長(zhǎng)短，分別采取相應(yīng)的技術(shù)措施。下面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(dāng)原地表面砌筑墻時(shí)，基坑挖深不得小于400mm，施工次序?yàn)椋合扔肕5水泥砂漿砌二層500寬磚基礎(chǔ)收臺(tái)砌一層370砌筑500高的240寬實(shí)心磚砌筑M1粘土砌筑墻，并以M5水泥砂漿砌筑。

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，在松軟的地面，砌筑圍墻時(shí)，基礎(chǔ)開挖深度不得少于500mm，施工順序?yàn)椋夯鄣撞看蚝籑5水泥砂漿砌筑四層磚砌墻時(shí)，基礎(chǔ)開挖不得少于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，在設(shè)置林帶邊和植被邊砌墻時(shí)，要考慮到林帶澆水和綠化微噴的影響，基礎(chǔ)深度不小于600mm，施工次序?yàn)椋合葷沧?00寬200mm厚C10混凝土M5水泥砂漿砌筑100mm高的240實(shí)心墻M1粘土砌筑墻。磚石砌好*靠近植被邊的邊墻和墻邊，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，砌墻時(shí)，磚與磚之間的間距應(yīng)按規(guī)范規(guī)定設(shè)置，一般為3~3，6m；砌筑空斗墻時(shí)，必須按“五斗一眠”砌筑，以確保圍墻整體穩(wěn)定。此外，還應(yīng)注意，磚墻邊不能堆土，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.
