臨邊護欄主要用作施工場所的圍欄，不僅可以節省的費用，還可以延長使用壽命幾年，當然臨邊護欄施工前各方面要預先準備，內容是怎樣的呢？

The edge fence is mainly used as the fence of the construction site, which can not only save the cost, but also extend the service life for several years. Of course, all aspects of the edge fence should be prepared in advance before construction. What is the content?

基礎：施工時，需要預埋柵欄格柵的鐵預埋件。

Foundation: during construction, iron embedded parts of fence grid shall be embedded.

結構：護欄網用55mm鋼管焊接在鋼板預埋件上，連接在一起。

Structure: the guardrail is welded to the steel plate embedded parts with 55mm steel pipe and connected together.

專用工具拉出設備的臨邊護欄。

Pull out the edge guardrail of the equipment with a special tool.

選擇建筑材料時，合理堆放材料，防止損壞材料;

When selecting building materials, stack materials reasonably to prevent damage to materials;

施工前確定施工位置，標出每一個需要立柱的點，確保工程質量;

Before construction, determine the construction position and mark each point requiring column to ensure the project quality;

施工過程中應遵循輕拿輕放的原則，避免損壞材料和地面。同時，施工時應避免噪音過大，以免影響周圍人的工作和生活。

The principle of handling with care shall be followed during construction to avoid damage to materials and ground. At the same time, excessive noise shall be avoided during construction to avoid affecting the work and life of surrounding people.

圍欄施工時，要先放線定位，保證施工時圍欄不會偏移。

During fence construction, setting out and positioning shall be carried out first to ensure that the fence will not deviate during construction.

連接鉤網時避免材料損壞;

Avoid material damage when connecting the hook net;

安裝橫向立柱時，應在固定和焊接前進行點對點和線對線找正;

When installing horizontal columns, point-to-point and line-to-line alignment shall be carried out before fixing and welding;

臨邊護欄施工工程期間，周圍不能進行其他施工。

During the construction of edge guardrail, no other construction can be carried out around.

臨邊護欄在施工初期，基礎是挖掘基坑，保護挖掘基坑，防止施工事故的發生，確保施工期間不發生事故，保證施工進度正常。安裝前的基坑屏障通常構造成使用機械膨脹螺栓，化學螺釘檢查和其他方法形成下部磚或混凝土澆筑和圍欄，以分解支柱鋼襯里部分以減少下面的直線。

At the initial stage of construction, the foundation of the edge guardrail is to excavate the foundation pit, protect the excavation foundation pit, prevent construction accidents, ensure that no safety accidents occur during construction, and ensure the normal construction progress. The foundation pit barrier before installation is usually constructed to form the lower brick or concrete pouring and fence by using mechanical expansion bolts, chemical screw inspection and other methods to decompose the steel lining part of the column to reduce the straight line below.

如果沒有形成下壁底部，鋼襯的長度可以直接埋在墻內，并在墻的固化期后正式建造。或者預先準備預制件，并將預制件和預制件焊接在柱子中。這種方法比螺栓連接更強，但前提是在施工過程中必須注意直線和水平線。鋼柱與鋼襯之間的距離與設計尺寸相同，以確保半成品可以連接到其上。

If the bottom of the lower wall is not formed, the length of the steel lining can be directly buried in the wall and formally constructed after the curing period of the wall. Or prepare the precast units in advance and weld the precast units and precast units in the column. This method is stronger than bolt connection, but the premise is that attention must be paid to the straight line and horizontal line during construction. The distance between the steel column and the steel lining shall be the same as the design dimension to ensure that the semi-finished products can be connected to it.

在直線上繪制兩條平行線，以便整個部分作為安裝和調整的參考。安裝后，確保基坑的上下端平整。護欄的十字架和鋼襯里已經安裝在施工現場之前，每個軸承的加強部分也就位。

Draw two parallel lines on the straight line so that the whole part can be used as a reference for installation and adjustment. After installation, ensure that the upper and lower ends of the foundation pit are flat. Before the cross and steel lining of the guardrail have been installed on the construction site, the reinforcement of each bearing is also in place.
