The construction of guardrails needs to meet the following standards:

标准：围挡护栏的施工必须符合相关的规范和标准，确保人员在施工过程中不会发生意外事故。例如，围挡护栏应牢固稳定，不得存在松动、倾斜或倒塌的情况。

Safety standards: The construction of guardrails must comply with relevant safety regulations and standards to ensure that personnel do not experience accidents during the construction process. For example, the guardrail should be firm and stable, and there should be no looseness, tilting, or collapse.

规范标准：围挡护栏的施工应符合或地区的相关规范和标准。这些标准包括围挡护栏的高度、间距、材质、防腐处理等要求，以确保围挡护栏能够正常起到隔离和保护作用。

Norms and standards: The construction of guardrails should comply with relevant national or regional norms and standards. These standards include requirements for the height, spacing, material, and anti-corrosion treatment of guardrails to ensure that they can function properly in isolation and protection.

美观标准：围挡护栏的施工应考虑到其外观效果，保证整体美观性。安装后应有一致的高度和对齐度，材料颜色搭配合理，与周边环境相协调。

Aesthetic standards: The construction of guardrails should consider their appearance to ensure overall aesthetics. After installation, there should be consistent height and alignment, reasonable material color matching, and coordination with the surrounding environment.

品质标准：围挡护栏的施工应使用符合质量要求的材料和工艺，确保围挡护栏的耐久性和稳定性。材料选择应符合规范要求，施工过程应严格按照工艺要求进行，确保围挡护栏的使用寿命和性能。

Quality standards: The construction of guardrails should use materials and processes that meet quality requirements to ensure the durability and stability of the guardrails. The material selection should comply with the requirements of the specifications, and the construction process should strictly follow the process requirements to ensure the service life and performance of the fence.

环境标准：围挡护栏的施工应尽量减少对周围环境的影响，比如降低施工噪音、减少粉尘扬尘等。需要遵守当地环境保护法律法规，配合相关部门的环境保护要求。

Environmental standards: The construction of guardrails should minimize the impact on the surrounding environment, such as reducing construction noise and dust. It is necessary to comply with local environmental protection laws and regulations, and cooperate with relevant departments' environmental protection requirements.

综上所述，围挡护栏施工需要满足、规范、美观、品质和环境等多个方面的标准，以保证施工质量和使用效果。

In summary, the construction of guardrails needs to meet multiple standards such as safety, regulation, aesthetics, quality, and environment to ensure construction quality and effectiveness.
