1. Fence positioning

依据业主下发的施工平面图和现场状况，对临时围挡进行测设定位。放完线后，请业主予以确认，与图纸不符部位及时进行调整。

Based on the construction plan and site conditions issued by the owner, measure and locate the temporary enclosure. After setting out the line, please confirm with the owner and make timely adjustments to any discrepancies with the drawings.

2、立柱及板块制作

2. Production of columns and plates

依据图纸及现场测量尺寸，计算出需要制作立柱与板块的数量。钢材进行防锈处理，刷红丹防锈漆两遍再将彩钢板用铆钉连接到方管龙骨上制成板块，制作好的立柱及板块龙骨都要进行防锈处理，涂刷两遍防锈漆。

Based on the drawings and on-site measurement dimensions, calculate the number of columns and plates that need to be made. The steel should be treated with rust prevention, painted with two coats of red lead rust prevention paint, and then riveted to the square tube keel to form a plate. The fabricated column and plate keel should be treated with rust prevention and coated with two coats of rust prevention paint.

3、基础施工

3. Foundation construction

，根据弹设好的围墙位置线及设计图纸要求，开挖基坑，基坑尺寸600mm*600mm*600mm，及400mm*400mm*400mm，开始浇筑C20混凝土基础;同时将制作完成的预埋件安装固定，预埋板采用150mm*150mm钢板，混凝土浇筑过程中严格按照标准施工。浇筑完毕后，及时覆盖并养护。

Firstly, according to the snapped position line of the fence and the requirements of the design drawings, excavate the foundation pit with dimensions of 600mm * 600mm * 600mm and 400mm * 400mm * 400mm, and start pouring C20 concrete foundation; At the same time, the completed embedded parts will be installed and fixed. The embedded plate will be made of 150mm * 150mm steel plates, and the concrete pouring process will be strictly carried out in accordance with national standards. After pouring, cover and maintain in a timely manner.

4、围挡板块安装

4. Installation of enclosure plate

待基础砼达到一定强度后，进行立柱、板块安装，均匀分隔，焊机焊接 到预埋板上，全部焊接完毕后，对焊接情况进行验收，合格后进行板块安装。彩钢板厚度为0.7mm，彩钢板间骨架横向方钢规格50mm×50mm×2.5mm，纵向方钢60mm×60mm×3.5mm，在每2.5米加焊斜撑 ，并且焊接完的位置重新做涂刷防锈处理。

After the foundation concrete reaches a certain strength, the columns and plates should be installed, evenly separated, and welded to the embedded plate by a welding machine. After all welding is completed, the welding situation should be inspected and accepted. After passing the inspection, the plates should be installed. The thickness of the color steel plate is 0.7mm, and the horizontal square steel specification between the color steel plates is 50mm × 50mm × 2.5mm, longitudinal square steel 60mm × 60mm × 3.5mm, slant support shall be welded every 2.5m, and the welded position shall be repainted for rust prevention.

5、围挡的维护：

5. Maintenance of enclosure:

围挡的作用的发挥以及良好的外部形象的体现关键在  日常的维护。安排一组人员进行维护。日常维护包括：破损的维修，人员分别安排1名员带领2名维护工人进行巡查维护。在夜间施工期间以及特殊天气期间增派人员进行巡查维护，确保。

The key to the safety function of the enclosure and the embodiment of a good external image lies in daily maintenance. Arrange a group of personnel for maintenance. Daily maintenance includes repairing damaged parts, with one safety officer and two maintenance workers arranged for inspection and maintenance. During nighttime construction and special weather periods, additional personnel are dispatched for inspection and maintenance to ensure safety.

二、质量保证措施：

2、 Quality assurance measures:

1、围挡的搭设应整齐、严密、牢固、美观。

1. The installation of fences should be neat, tight, firm, and aesthetically pleasing.

2、围挡施工过程中，彩钢板不能出现锈迹，要涂有保护材料。

2. During the construction process of the enclosure, the colored steel plate should not show rust and should be coated with protective materials.

3、围挡施工完毕，彩钢板与钢管之间、钢管与钢管之间必须连接牢固，不得有松动现象。

3. After the enclosure construction is completed, the connection between the color steel plate and the steel pipe, as well as between the steel pipe and the steel pipe, must be firm and there must be no looseness.

4、围挡施工完毕，板与板之间衔接平顺，直线段要在一条直线上；板与板之间不能留有明显较大缝隙

4. After the enclosure construction is completed, the connection between the boards should be smooth, and the straight section should be in a straight line; There should be no significant gaps between the boards
