The edge guardrail is not uncommon in life. It can effectively protect the safety of personnel, prevent personnel from falling into the well, prevent safety accidents and prevent construction personnel from slipping and falling into the foundation pit. It is a good safety protection equipment to ensure the construction personnel, so the construction of the border guardrail is very important. So do you know the use effect of the edge guardrail?

　　臨邊護欄是根據地基施工方向、地基高度和地基平面尺寸挖的坑。主要用于打地基。通常業內人士比較了解基坑邊沿護欄的客戶，有時會解釋說用柱子連接的施工坑起到維護作用，其中高約1.2米，長約2米，并且有警告噴霧標志。

　　Adjacent guardrail is a pit dug according to foundation construction direction, foundation height and foundation plane size. It is mainly used for foundation. Generally, industry insiders who understand the guardrail on the edge of the foundation pit will sometimes explain that the construction pit connected by columns plays a maintenance role, which is about 1.2 meters high and 2 meters long, and has a warning spray sign.

　　公告顏色為黃色、黑色或紅色和白色。你應該知道基坑邊緣護欄的施工方法。現場澆筑基礎，人工開挖基坑。對于人工挖不到的部分巖石，請用氣鎬或氣槍挖一個淺孔，輔以弱爆破，挖土坑壁，下層巖坑壁垂直。

　　Announcement colors are yellow, black or red and white. You should know the construction method of the guardrail on the edge of the foundation pit. Site casting foundation, artificial excavation foundation pit. For the part of the rock that cannot be dug manually, please dig a shallow hole with an air pick or air gun, supplemented by weak blasting, dig the pit wall, and the lower pit wall is vertical.

　　臨邊護欄基坑開挖坡度取決于地面，基坑尺寸應符合基坑輪廓。安裝混凝土基礎前，及時檢查基坑的尺寸、平面方向、地面平整度和密封性，然后繼續進行基礎施工。基礎檢查：在灌注基礎混凝土之前，應進行隱蔽工程檢查。

　　The excavation slope of the adjacent guardrail depends on the ground, and the size of the foundation pit should conform to the contour of the foundation pit. Before installing the concrete foundation, check the size, plane direction, flatness and tightness of the foundation pit in time, and then continue the foundation construction. Foundation inspection: Concealed works should be inspected before foundation concrete is poured.

　　搭設臨邊防欄時，應符合規定，比如防護欄桿應由上、下兩道橫桿及欄桿柱組成，桿離地高度為1.0～1.2m，桿離地高度為0.5～0.6m。坡度大于1/2.2的屋面，防護欄桿應高1.5m，并掛網。除經設計外計算外，橫桿長度大于2m時，必須加設欄桿柱。

　　When the border guard railing is built, it should comply with the provisions. For example, the protective railing should be composed of the upper and lower two bars and the railing column. The height of the bar from the ground is 1.0 ~ 1.2m, and the height of the bar from the ground is 0.5 ~ 0.6m. For roofs with a slope greater than 1/2.2, the protective railing should be 1.5m high and a safety net should be hung. In addition to the design calculation, when the length of the crossbar is greater than 2m, a railing column must be added.
