在城市的建設(shè)進(jìn)程中，工程圍擋是隨處可見(jiàn)的存在。它們不僅是施工現(xiàn)場(chǎng)的 “守護(hù)者”，默默承擔(dān)著多重關(guān)鍵角色，更是城市形象的微妙展示者。

In the process of urban construction, engineering fences are ubiquitous. They are not only the "guardians" of the construction site, silently assuming multiple key roles, but also subtle exhibitors of the city's image.

從類型上看，工程圍擋可謂豐富多樣。彩鋼圍擋以彩鋼板為核心材料，重量輕、耐腐蝕，安裝簡(jiǎn)便靈活，能多次循環(huán)使用，對(duì)于道路施工、橋梁建設(shè)這類短期施工項(xiàng)目或是需要頻繁拆除挪用的工程而言，是絕佳選擇。PVC 圍擋由聚乙烯和鈣粉制成，韌性好、光潔度高、美觀易清潔 ，耐用性長(zhǎng)，常用于房屋建設(shè)、地鐵施工等長(zhǎng)期固定施工場(chǎng)景，盡管安裝稍顯麻煩，拆除再挪用時(shí)會(huì)有一定損耗。金屬圍擋以鋼板為主要材質(zhì)，強(qiáng)度高、不易變形，美觀度和光潔度都較高，使用年限能達(dá)到 3 年以上，多應(yīng)用于高速公路建設(shè)、橋梁施工等重要施工場(chǎng)所，不過(guò)使用時(shí)需注意維護(hù)保養(yǎng)，防止其變形。裝配式圍擋由預(yù)制構(gòu)件組成，標(biāo)準(zhǔn)化設(shè)計(jì)使其便于運(yùn)輸和存儲(chǔ)，可快速安裝和拆除，適合工期在 1 個(gè)月以上的施工現(xiàn)場(chǎng)。砌體圍擋采用空心磚、水泥砂漿等材料砌筑，抗風(fēng)強(qiáng)度高、結(jié)構(gòu)穩(wěn)固，適用于工期較長(zhǎng)、位于特殊地段（如機(jī)場(chǎng)、火車站）的主體結(jié)構(gòu)施工圍擋，但安裝和拆除過(guò)程復(fù)雜耗時(shí)。

移動(dòng)式圍擋包括水馬和鐵馬等，輕便易操作，能根據(jù)施工進(jìn)度快速調(diào)整，適用于工期在 15 天以下的管線改遷施工圍擋。園林綠化工程圍擋適用于 7 天以內(nèi)的園林綠化工程，兩側(cè)設(shè)置砂袋壓重，下腳噴刷黃黑相間的交通安全斑馬紋，既隔離又能融入園林環(huán)境。應(yīng)急搶險(xiǎn)工程圍欄框架采用鍍鋅管和鍍鋅板制作，表面粘貼反光膜，注明工程類型和建設(shè)單位，高可見(jiàn)性和警示效果能在夜間或低能見(jiàn)度時(shí)提供安全警示 ，用于應(yīng)急搶險(xiǎn)工程。

From the perspective of types, engineering enclosures can be described as diverse and abundant. Color steel fence is made of color steel plate as the core material, which is lightweight, corrosion-resistant, easy and flexible to install, and can be reused multiple times. It is an excellent choice for short-term construction projects such as road construction and bridge construction, or projects that require frequent demolition and diversion. PVC fences are made of polyethylene and calcium powder, with good toughness, high smoothness, beautiful appearance, easy cleaning, and long durability. They are commonly used in long-term fixed construction scenarios such as housing construction and subway construction. Although installation may be a bit cumbersome, there may be some wear and tear when dismantled and reused. Metal fences are mainly made of steel plates, which have high strength, are not easily deformed, have high aesthetics and smoothness, and can be used for more than 3 years. They are mostly used in important construction sites such as highway construction and bridge construction. However, maintenance and care should be taken during use to prevent deformation. Prefabricated enclosures are composed of prefabricated components, standardized design makes them easy to transport and store, can be quickly installed and removed, and are suitable for construction sites with a construction period of more than one month. The masonry enclosure is made of hollow bricks, cement mortar and other materials, with high wind resistance and stable structure. It is suitable for the construction of main structures in special areas with long construction periods (such as airports and train stations), but the installation and removal process is complex and time-consuming. Mobile enclosures include water horses and iron horses, which are lightweight and easy to operate. They can be quickly adjusted according to the construction progress and are suitable for pipeline relocation construction enclosures with a construction period of less than 15 days. The enclosure for landscaping projects is suitable for landscaping projects within 7 days. Sand bags are placed on both sides to press and yellow and black traffic safety zebra stripes are sprayed on the bottom of the fence, which not only isolates but also integrates into the landscaping environment. The fence frame for emergency rescue projects is made of galvanized pipes and galvanized sheets, with reflective film pasted on the surface, indicating the project type and construction unit. The high visibility and warning effect can provide safety warnings at night or in low visibility, and is used for emergency rescue projects.

這些圍擋的功能不容小覷。首要功能是分隔施工區(qū)域，明確劃分出施工場(chǎng)地與外部環(huán)境的界限，阻止無(wú)關(guān)人員隨意進(jìn)入施工區(qū)域，保障施工安全有序進(jìn)行，同時(shí)也讓行人免受施工過(guò)程中的潛在危險(xiǎn)。在降噪防塵方面，圍擋能有效降低施工噪音向外傳播，減少對(duì)周邊居民和環(huán)境的干擾；阻擋施工產(chǎn)生的塵土飛揚(yáng)，一定程度上改善空氣質(zhì)量。而且，圍擋還具備安全警示功能，通過(guò)在圍擋上設(shè)置醒目的安全警示標(biāo)志、標(biāo)語(yǔ)，提醒過(guò)往行人、車輛注意施工安全，避免發(fā)生意外事故。從城市形象展示角度來(lái)講，設(shè)計(jì)美觀、內(nèi)容積極的圍擋能成為城市街頭獨(dú)特的風(fēng)景線。比如在圍擋上張貼城市文化宣傳畫、公益廣告、項(xiàng)目效果圖等，不僅美化了施工區(qū)域周邊環(huán)境，還傳播了城市文化、展示了項(xiàng)目特色，提升了城市的整體形象和文化內(nèi)涵 。

The function of these fences should not be underestimated. The primary function is to separate the construction area, clearly delineate the boundary between the construction site and the external environment, prevent unrelated personnel from entering the construction area at will, ensure safe and orderly construction, and also protect pedestrians from potential dangers during the construction process. In terms of noise reduction and dust prevention, enclosures can effectively reduce the outward propagation of construction noise and minimize interference with surrounding residents and the environment; Blocking the dust generated by construction can improve air quality to a certain extent. Moreover, the fence also has a safety warning function. By setting up prominent safety warning signs and slogans on the fence, pedestrians and vehicles passing by are reminded to pay attention to construction safety and avoid accidents. From the perspective of urban image display, well-designed and actively designed fences can become unique scenic spots on the streets of the city. For example, posting urban cultural propaganda posters, public service advertisements, project renderings, etc. on the fence not only beautifies the surrounding environment of the construction area, but also spreads urban culture, showcases project characteristics, and enhances the overall image and cultural connotation of the city.

工程圍擋的類型與功能緊密相連，共同服務(wù)于城市建設(shè)，在保障施工安全、維護(hù)城市環(huán)境、展示城市形象等方面發(fā)揮著不可或缺的作用 。我們應(yīng)重視工程圍擋的合理選擇與設(shè)計(jì)，讓其在城市發(fā)展中展現(xiàn)更大價(jià)值。

The types and functions of engineering enclosures are closely linked, serving urban construction together and playing an indispensable role in ensuring construction safety, maintaining the urban environment, and showcasing the city's image. We should attach importance to the reasonable selection and design of engineering enclosures, so that they can demonstrate greater value in urban development.
