In order to prevent people from accidentally falling into the foundation pit, the baseboard above the foundation pit wall at the construction site is painted black, yellow or white. The red warning can effectively surround the surrounding pedestrians or vehicles.

由于基坑圍欄的網眼很小，因此可以防止碎屑掉入基坑，并防止工人因掉落物體而發生事故。

Due to the small mesh of the foundation pit fence, it can prevent debris from falling into the foundation pit and prevent accidents caused by falling objects for workers.

施工現場圍欄作為地面防護時，可有效防止墜落危險。

When fence is used as ground protection on the construction site, it can effectively prevent the risk of falling.

用作人車分離通道的分離功能，施工現場人員和車輛的有序分離減少了事故的發生。

The separation function used as a pedestrian vehicle separation channel reduces the occurrence of accidents by orderly separation of personnel and vehicles on the construction site.

基坑圍欄也稱為邊緣保護圍欄，基坑圍欄的一般高度為1.2*2米，表面采用更多醒目的顏色比如黃色和黑色，白色和紅色，起到了很好的警告作用。分類不同的產品主要區別在于，金屬絲，鐵板和鋼管的厚度不同，使用壽命也不同。

Foundation pit fences, also known as edge protection fences, generally have a height of 1.2 * 2 meters, and the surface adopts more eye-catching colors such as yellow and black, white and red, providing a good warning effect. The main difference between products with different classifications lies in the thickness and service life of metal wires, iron plates, and steel pipes.

基坑側圍的高度和設施：

The height and facilities of the side wall of the foundation pit:

基坑護欄的側面防護由20×30mm的方形矩形管制成，護欄柱由50×50mm（或40*40mm或60*60）的方形矩形管制成，底座用膨脹螺栓牢固地固定在地面上。

The side protection of the foundation pit guardrail consists of 20 × Made of 30mm square rectangular tube, with guardrail columns made of 50 × Made of 50mm (or 40 * 40mm or 60 * 60) square rectangular tube, the base is firmly fixed to the ground with expansion bolts.

基坑護欄的護欄柱高度不應小于1200mm，離列中間的距離為2000mm。表面應噴涂紅色，白色或黑色和黃色警告涂料，中間位置應設置警告標語牌，底部應設置200mm（180mm）高的紅色，白色或黑色和黃色腳擋。

The height of the guardrail column of the foundation pit guardrail should not be less than 1200mm, and the distance from the middle of the column should be 2000mm. The surface should be sprayed with red, white, black, and yellow warning paint, with warning signs set in the middle and 200mm (180mm) high red, white, black, and yellow foot stops set at the bottom.

基坑排水措施要做好，排水溝設在基坑防護欄桿的外側，可以有效地排水。它不能安裝在基坑周圍有水的地方，以防止因進水而導致基坑倒塌。

The drainage measures for the foundation pit should be taken well, and the drainage ditch should be set outside the protective railing of the foundation pit to effectively drain water. It cannot be installed in areas with water around the foundation pit to prevent it from collapsing due to water ingress.

在基坑護欄周圍設置夜間警告燈，或在基坑護欄上懸掛夜間發光裝置。

Install night warning lights around the foundation pit guardrail, or hang night lighting devices on the foundation pit guardrail.

警告標志可以懸掛在基坑護欄的外部。

Warning signs can be hung outside the foundation pit guardrail.

基坑護欄廣泛用于建筑工地邊界保護，配電維護，電氣維護，改建，運輸，公司警戒線及其他停車場所等。

Foundation pit guardrails are widely used for boundary safety protection at construction sites, power distribution maintenance, electrical maintenance, renovation, transportation, company warning lines, and other parking spaces.

基坑護欄的應用使施工現場更加整潔美觀，文明；防止經過的汽車離基坑邊緣太近而導致倒塌；防止工人意外掉入基坑；防止碎屑掉入基坑中，從而對基坑中的操作人員造成傷害。

The application of foundation pit guardrails makes the construction site cleaner and more beautiful, civilized and safe; Prevent passing cars from being too close to the edge of the foundation pit and causing collapse; Prevent workers from accidentally falling into the foundation pit; Prevent debris from falling into the foundation pit, thereby causing injury to operators in the pit.

加強施工現場的保護非常重要，特別是在容易發生事故的地方，例如基坑保護，地面保護和屋頂保護。

Strengthening the safety protection of construction sites is very important, especially in areas prone to safety accidents, such as foundation pit protection, ground protection, and roof protection.
