In order to standardize the setting and management of safety protection facilities on construction sites and improve the level of safety protection on construction sites, the project department pursues an organic unity of internal quality and external taste, with the goal of "high-quality durability, safety and comfort, economic and environmental protection, and recognition by units at all levels" as the construction safety management goal. The project department has determined the location, installation form, maintenance and replacement of safety protection facilities in key parts of the project, The aim is to improve the convenience, recyclability, and economic practicality of the installation, use, maintenance, and dismantling of safety protection facilities on construction sites. Various safety protection standards are proposed and issued for reference and guidance of the construction personnel of Qinyi Fifth Standard, promoting the development of safety protection facilities on construction sites towards standardization, modularization, assembly, and industrialization.

基坑周围宜操纵钢管+拆卸式护栏停止防护，钢管防护雕栏高度不得小于1.2m，由高低2道横杆构成，雕栏柱间距不得大于2m，钢钢应操纵扣件停止毗连，当钢管护栏施作实现后在外侧装置拆卸式护栏片，吊挂“基坑风险请勿接近”、“制止逾越”、“制止倚靠”等警示标识，同时应在护栏周围设置夜间警示灯。（需注重：临边防护雕栏间隔基坑边缘间隔不得小于0.5m）

Steel pipes and prefabricated guardrails should be used for protection around the foundation pit. The height of the steel pipe guardrail should not be less than 1.2m, consisting of two horizontal bars above and below. The spacing between railing columns should not be greater than 2m. Steel bars should be connected using fasteners. After the construction of the steel pipe guardrail is completed, prefabricated guardrails should be installed on the outside, and warning signs such as "Do not approach the danger of the foundation pit", "No crossing", and "No leaning" should be hung, At the same time, night warning lights should be installed around the guardrail. (Please note that the distance between the edge protective railing and the edge of the foundation pit should not be less than 0.5m.)

基坑临边防护栏在都会中的利用非常遍及，合用规模：基坑临边防护栏合用于基坑周边地区的围护及施工地区的断绝分开。修建施工工地的基坑白菜彩金社区菜园子 罕见的色彩有黄黑相间、红白相间两种，外形既有方管的也有铁丝护栏。基坑白菜彩金社区菜园子 在修建施工现场首要起避免人身危险的须要防护举措措施，它合用于各种施工现场。接纳热浸镀锌资料，严酷根据图纸建造，尺寸准确，焊点安稳，到达宁静防护的目标。基坑白菜彩金社区菜园子 能够让施工现场整齐雅观，文化宁静，能够避免交往的车辆太接近基坑边缘形成塌方而激发宁静变乱，还能够避免施工工人掉进基坑内，避免杂物落入基坑内，从而对基坑内的施工工人形成人身危险。

The application of foundation pit edge protection fence is very common in cities, and its scope of application: The foundation pit edge protection fence is suitable for the enclosure of the surrounding area of the foundation pit and the isolation and separation of the construction area. The common colors for the edge guardrails of foundation pits on construction sites are yellow black and red white, with shapes ranging from square tubes to wire guardrails. The edge guardrail of the foundation pit mainly serves as a necessary protective device to prevent personal injury on construction sites, and is suitable for various construction sites. Made of hot-dip galvanized material, strictly according to the drawings, with correct dimensions and firm welding points, achieving the purpose of safety protection. The edge guardrail of the foundation pit can make the construction site clean and beautiful, civilized and safe, prevent vehicles from coming too close to the edge of the foundation pit and causing safety accidents due to collapse, and also prevent construction workers from falling into the foundation pit, preventing debris from falling into the foundation pit and causing personal injury to construction workers inside the foundation pit.
