The characteristic of color steel plate enclosure is that it does not require bricklaying, cement pier foundation, fading, deformation, and frequent repair. When in use, regardless of whether the equipment is disassembled or not, it is convenient and can be reused. Its strength, fearlessness, and performance are comparable, with rich colors and affordable prices. The front of the colored steel plate enclosure equipment is usually a lower foundation that has been constructed by civil engineering to support brick masonry or concrete pouring.

護欄可通過機械螺栓膨脹和化學螺絲檢查等方式固定在下部基礎的中間，這樣就可以均勻的分布在一條直線上。如果彩鋼板圍擋下部基礎未成型，建議通過增加其長度將柱的鋼襯直接嵌入墻體中，待墻體保護期結束后即可開始施工，或將預制好的預埋件鋪設在墻面上。今后，柱的鋼襯將與預埋件焊接焊接在一起。

The guardrail can be fixed in the middle of the lower foundation through mechanical bolt expansion and chemical screw inspection, so that it can be evenly distributed in a straight line. If the lower foundation of the color steel plate enclosure is not formed, it is recommended to directly embed the steel lining of the column into the wall by increasing its length. Construction can start after the wall protection period ends, or the prefabricated embedded parts can be laid on the wall. In the future, the steel lining of the column will be welded together with the embedded parts.

兩種方式的特點都強于螺栓連接，但預設時改成要注意直線和度線。立柱鋼襯的間隔改成要符合設計標準，預裝的半廢品可以與之連接。在直線區間的全斷面上畫出下限的兩條平行線作為設備調整基準，設備完工后護欄上下端的平直度。

Both methods have stronger characteristics than bolted connections, but when preset, attention should be paid to straight and diagonal lines. The spacing of the column steel lining should be changed to meet the design standards, and pre installed semi-finished products can be connected to it. Draw two parallel lines at the lower limit on the entire cross-section of the straight section as the equipment adjustment benchmark, and measure the flatness of the upper and lower ends of the guardrail after the equipment is completed.

護欄的水平和垂直鋼襯在出廠前已經安裝連接完畢，各受力點的加固配件也已配備到位?，F場施工時，只需將護欄的水平襯與立柱連接固定即可。彩鋼板圍擋作為一種新型圍護結構，目前正在建設單位的建筑工程中使用。

The horizontal and vertical steel lining of the guardrail has been installed and connected before leaving the factory, and the reinforcement accessories for each stress point have also been equipped in place. During on-site construction, simply connect and fix the horizontal lining of the guardrail to the column. Color steel plate enclosure, as a new type of enclosure structure, is currently being used in construction projects of construction units.

因為施工圍擋一般都是設置在一些人群多的地方，所以需要能夠應對施工上的各種情況的發生，比如開挖過程中周邊工地圍擋可能受到影響，可能導致施工圍擋坍塌的危險，這方面需要提前做好防護措施。

Because construction fences are usually set up in crowded areas, it is necessary to be able to cope with various situations during construction. For example, during the excavation process, the surrounding construction site fences may be affected, which may lead to the risk of construction fence collapse. In this regard, protective measures need to be taken in advance.

1、在指揮部、總監辦、駐地監理組的對立指導下，項目部根據施工圍擋塌方的理論情況，采取不同的應急措施，確定行車無危險。

1. Under the opposing guidance of the command center, director's office, and resident supervision team, the project department takes different emergency measures based on the theoretical situation of construction enclosure collapse to ensure that there is no danger in driving.

2、根據總部要求，在每個圍擋后面增加活動支架，在每個施工圍擋，后面增加三根方管支架，利用三角鐵、方管和焊接，將路邊防撞護欄柱作為一個整體進行活動。

2. According to headquarters requirements, movable brackets are added behind each fence, and three square tube brackets are added behind each construction fence. Triangle iron, square tube, and welding are used to move the roadside anti-collision guardrail column as a whole.

3、將原來的每十個圍場一個空心圍場改為每三個圍場一個空心圍場，以減少風的阻力。

3. Change the original one hollow enclosure for every ten enclosures to one hollow enclosure for every three enclosures to reduce wind resistance.

4、每兩個圍擋之間有一個帶有箭頭導向傾向的紅色反光警示牌，有利于夜間行車確定。此外，圍擋上方每隔500米設置一個限速80CM或“慢行”的標志。

4. There is a red reflective warning sign with arrow orientation between each two fences, which is conducive to determining nighttime driving. In addition, a speed limit of 80CM or "slow moving" sign is set every 500 meters above the fence.
