工程施工现场都要圈围，建筑工地用围墙，市政工地除部分有条件的做围墙外，在城区不断交通的情况下，只能用临时围挡，把施工作业区域圈围起来，与不施工或暂时不施工的道路隔开的临时设施。

The construction site of the project should be enclosed. The construction site should be fenced. In addition to some conditional fences, the municipal construction site can only use temporary fences to enclose the construction area and separate it from the roads that are not under construction or temporarily under the condition of continuous traffic in the urban area.

工程施工围挡作用有：

The engineering construction enclosure functions include:

1、在围挡内施工，以减小对周边环境的影响。

1. Construct in the enclosure to reduce the impact on the surrounding environment.

2、防止非施工人员串入影响施工。

2. Prevent non construction personnel from affecting the construction.

3、保护施工机械设备(组成：驱动装置、变速装置等)、成品、半成品。

3. Protect construction machinery and equipment (composition: drive device, speed change device, etc.), finished products and semi-finished products.

4、防止其他人员进入工地发生意外事故。

4. Prevent other personnel from entering the construction site and causing accidents.

工程施工在打围上存在的问题很多：

There are many problems in the siege of the project construction:

一、围挡没有打全，大多只在车行道一侧有围挡，形成;半开放式;，行人在施工作业区穿行，未起到隔离作用，作用是挡住了车行道方向的“眼球。

1、 The enclosure is not fully opened, and most of them only have enclosures on one side of the roadway, forming; Semi open;, Pedestrians walking through the construction area did not play an isolation role, but blocked the "eyeball" in the direction of the roadway.

二、围挡没做到定期整理、清洗、保洁，管理不到位，部分围挡破损、不整齐，有碍观瞻。

2、 Fences are not regularly sorted, cleaned and cleaned, and management is not in place. Some fences are damaged and untidy, which is unsightly.

三、围挡搭设不规范、不统一，有的用高围挡，有的用低围挡，有的用活动档板。

3、 The erection of fences is not standardized and unified. Some use high fences, some use low fences, and some use movable baffles.

四、部分围档搭投不牢，出现歪斜倒塌，形成隐患。

4、 Some fences are not erected and cast firmly, which leads to deflection and collapse, forming potential safety hazards.

五、搭设施工有一定难度，对围挡设置处的路面有条件要求，往往开始围挡搭得还不错，拆移后围挡搭不好。围挡的这些基本作用决定了施工围挡的必要性。

5、 There are certain difficulties in the erection construction. There are conditional requirements for the pavement where the fence is set. The fence is often set up well at the beginning, but it is not good after removal. These basic functions of enclosure determine the necessity of construction enclosure.

以下是围挡施工小编认为较好的几种施工方法，仅供参考：

The following are several construction methods that the enclosure construction team believes are better for reference only:

1.在原土地面上砌筑围墙时，基础开挖深度应不小于400mm。

1. When building the enclosure on the original soil ground, the foundation excavation depth shall not be less than 400mm.

2.在松软的地面上，砌筑围墙时，基础开挖深度应不小于500mm。

2. On the soft ground, when building the enclosure, the foundation excavation depth should not be less than 500mm.

3.在林带边和植被边砌筑围墙时，先要考虑林带浇水和绿化微喷的影响，基础深度应不小于600mm。

3. When building fences near the forest belt and vegetation, the influence of forest belt watering and greening micro spraying should be considered first, and the foundation depth should not be less than 600mm.

4.围墙砌筑时，砖垛的间距须按照规范要求设置。

4. When the enclosure is built, the spacing of brick stacks must be set according to the specification requirements.

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。总之，如果想不出问题的更好的进行施工就要多注意这些事项，更多内容就来我们网站//www.hongdaxinwuliu.com吧。

Another thing to note is that it is strictly forbidden to pile soil, sand and gravel or other building materials on the side of the built fence. In short, if you want to better carry out the construction without problems, you should pay more attention to these matters, and come to our website for more content //www.hongdaxinwuliu.com OK.
