圍擋安裝方法及施工:施工圍擋通常用于道路改造，建設(shè)，樓盤現(xiàn)場(chǎng)施工及房地產(chǎn)項(xiàng)目，圍擋主體結(jié)構(gòu)為鋼結(jié)構(gòu)，多數(shù)情況下以角鋼焊接的方籠為主立柱，在一些特殊路段也有用矩形管、球形網(wǎng)件等連接，地基澆筑大小受施工現(xiàn)場(chǎng)土質(zhì)、受風(fēng)大小影響。面板部分主要用鍍鋅板封面，還有部分用彩鋼板，此種工藝圍擋高度2~8米，畫面及照明設(shè)施，一般與甲方協(xié)商，噴涂企業(yè)名稱、安全、質(zhì)量、文明施工用語及開發(fā)項(xiàng)目商業(yè)廣告，嚴(yán)禁張貼、涂寫垃圾廣告。彩鋼圍擋效率高、機(jī)動(dòng)靈活，快速拆裝簡(jiǎn)單快捷牢固。全新，可反復(fù)拆裝使用，甚可100%回收利用。占用空間小，使用壽命長(zhǎng)，經(jīng)濟(jì)實(shí)用、很有效的降低了工程圍擋建設(shè)的成本。施工圍擋采用鋼管及彩鋼板等材料，具體施工方法如下：

　　Installation method and construction of enclosure: Construction enclosure is usually used for road renovation, construction, on-site construction of real estate projects, and real estate projects. The main structure of the enclosure is a steel structure, and in most cases, square cages welded with angle steel are used as the main columns. In some special sections, rectangular pipes, spherical mesh and other connections are also used. The size of the foundation pouring is affected by the soil and wind conditions at the construction site. The panel is mainly covered with galvanized sheet metal, and some parts are made of color steel plates. This process has a fence height of 2-8 meters, and the image and lighting facilities are generally negotiated with the party A. The company name, safety, quality, civilized construction language, and commercial advertisements for the development project are sprayed, and it is strictly prohibited to post or write garbage advertisements. The color steel fence has high efficiency, flexible maneuverability, and is easy, fast, and sturdy to disassemble and assemble quickly. Brand new and environmentally friendly, can be disassembled and reused repeatedly, and even 100% recyclable. Small space occupation, long service life, economical and practical, effectively reducing the cost of engineering enclosure construction. The construction fence is made of materials such as steel pipes and color steel plates. The specific construction method is as follows:

　　(1)使用的材料：直徑80*80壁厚0.8mm鋼管、黑黃板、20*50U型槽橫管、厚度為0.3-0.5mm彩鋼板，斜撐和背撐。

　　(1) Materials used: steel pipe with a diameter of 80 * 80 and a wall thickness of 0.8mm, black yellow plate, 20 * 50U groove horizontal pipe, color steel plate with a thickness of 0.3-0.5mm, slant support and back bracing.

　　(2)立柱及橫桿的設(shè)置：沿施工區(qū)及臨舍周邊每3.15米設(shè)置一根立柱，要求立柱為80*80壁厚0.8鋼管，每支長(zhǎng)2.5米。立柱下座為50cm×50cm×50cm的C25砼基礎(chǔ)，鋼柱底板四角采用膨脹螺栓與混凝土基礎(chǔ)連接固定。

　　(2) The setting of columns and crossbars: One column is set every 3.15 meters along the construction area and the surrounding area of the temporary building. The columns are required to be 80 * 80 steel pipes with a wall thickness of 0.8, and each column is 2.5 meters long. The lower seat of the column is a C25 concrete foundation of 50cm × 50cm × 50cm, and the four corners of the steel column bottom plate are connected and fixed to the concrete foundation with expansion bolts.

　　(3)擋墻的設(shè)置：用彩鋼板和U型槽管組成框架，在長(zhǎng)向加設(shè)一道橫撐，將彩鋼板用自攻螺絲固定在U型槽架上，要求必須牢固;然后用8#鍍鋅鐵絲將做好成片的彩鋼圍擋固定在橫桿上;為防止大風(fēng)影響，考慮每片彩鋼圍擋間隔10cm，以增加圍擋墻的整體抗風(fēng)性。

　　(3) The setting of the retaining wall: Firstly, a frame is composed of color steel plates and U-shaped groove pipes. A transverse brace is added in the longitudinal direction, and the color steel plates are fixed to the U-shaped groove frame with self tapping screws, which must be firm; Then use 8 # galvanized iron wire to fix the finished color steel fence on the crossbar; To prevent the impact of strong winds, consider spacing each piece of color steel fence by 10cm to increase the overall wind resistance of the fence wall.

　　(4)圍擋的支撐：為了圍擋墻的牢固性，防止被風(fēng)吹倒，每間隔6m設(shè)置一道鋼管斜撐;斜撐上部用架扣固定在橫桿上，底部將底板用膨脹螺絲固定。

　　(4) Support of enclosure: a steel pipe slant support is set every 6m to ensure the firmness of the enclosure wall and prevent it from being blown down by the wind; The upper part of the slant support is fixed on the cross bar of the top layer with a frame buckle, and the bottom plate is fixed with expansion screws.

　　(5)圍擋施工完畢，板與板之間銜接平順，直線要在一條直線上;板與板不得留有縫隙，即在場(chǎng)外不能看見場(chǎng)內(nèi)施工。圍擋沿線設(shè)置紅燈或者隔斷用安全反光錐用于夜間警示。

　　(5) After the fence construction is completed, the connection between the boards should be smooth, and the straight line should be on the same straight line; There must be no gaps between the boards, meaning that construction cannot be seen from outside the site. Red lights or safety reflective cones are set up along the perimeter fence for nighttime warning.
