First, let's understand the construction enclosure. The main function of construction enclosure is to isolate the construction site from the external environment and make the construction site a relatively closed space, so as to ensure the smooth progress of construction and avoid pedestrians entering by mistake and safety accidents.

施工圍擋的結(jié)構(gòu)包括選擇各種砌體材料砌筑圍護結(jié)構(gòu)，選擇各種成形的板材以形成一個整體。保護體通常采用機械膨脹螺栓和化學(xué)螺紋檢測，將柱底部的鋼基板固定在下部底座中心，均勻分布，磚石或混凝土澆筑的下部底座是由土木工程建造的。

The construction enclosure structure includes the selection of various masonry materials to build the enclosure structure, and the selection of various formed plates to form a whole. The protective body is usually detected by mechanical expansion bolts and chemical threads. The steel base plate at the bottom of the column is fixed in the center of the lower base and evenly distributed. The lower base of masonry or concrete pouring is built by civil engineering.

還有一種方法就是將立柱的鋼襯直接埋入墻內(nèi)，直墻體的維修周期得以正式建造;或者將預(yù)制嵌入件放置在壁面上，柱的鋼襯應(yīng)與埋置的部分電熔焊接。設(shè)置時一定要要注意直線和水平線。

Another method is to bury the steel lining of the column directly into the wall until the maintenance cycle of the wall can be formally built; Alternatively, the prefabricated inserts shall be placed on the wall, and the steel lining of the column shall be electrofusion welded with the embedded part. Be sure to pay attention to straight lines and horizontal lines when setting.

另外，為保證在護欄裝置完成后，確保上端和下端的平直度在直線區(qū)間內(nèi)，要采用上下兩條平行線對基準(zhǔn)進行調(diào)整。柱與鋼襯里之間的間距必須與規(guī)劃尺度一致，以確保預(yù)組裝的半成品可以與它連接。

In addition, in order to ensure that the straightness of the upper and lower ends is within the straight-line interval after the completion of the guardrail device, the upper and lower parallel lines shall be used to adjust the benchmark. The dimension of the pre assembled steel column must be consistent with that of the pre assembled steel column to ensure that it can be connected with the finished steel column.

要注意的是，在現(xiàn)場施工中，只有護欄和立柱的橫向襯砌需要連接和固定。所以在離開工廠之前，安裝和連接護欄的橫向和剛性鋼襯里一定要各種軸承點的加固配件。

It should be noted that during site construction, only the transverse lining of guardrail and column needs to be connected and fixed. Therefore, before leaving the factory, the transverse and rigid steel lining of the guardrail must be reinforced with various bearing points.

為營造武漢市整潔、清爽、干凈、美麗的城市形象，將武漢創(chuàng)建成更的文明城市，在當(dāng)前大力建設(shè)發(fā)展的重要時期，推進市政道路施工圍擋及圍擋廣告提質(zhì)提檔，非常重要。

In order to create a clean, refreshing, clean and beautiful city image of Wuhan and build Wuhan into a more advanced civilized city, it is very important to promote the comprehensive improvement of municipal road construction fence and fence advertising in the important period of vigorous construction and development.
