The construction of guardrails needs to meet the following standards:

標準：圍擋護欄的施工必須符合相關的規范和標準，確保人員在施工過程中不會發生意外事故。例如，圍擋護欄應牢固穩定，不得存在松動、傾斜或倒塌的情況。

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.

規范標準：圍擋護欄的施工應符合或地區的相關規范和標準。這些標準包括圍擋護欄的高度、間距、材質、防腐處理等要求，以確保圍擋護欄能夠正常起到隔離和保護作用。

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.

美觀標準：圍擋護欄的施工應考慮到其外觀效果，保證整體美觀性。安裝后應有一致的高度和對齊度，材料顏色搭配合理，與周邊環境相協調。

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.

品質標準：圍擋護欄的施工應使用符合質量要求的材料和工藝，確保圍擋護欄的耐久性和穩定性。材料選擇應符合規范要求，施工過程應嚴格按照工藝要求進行，確保圍擋護欄的使用壽命和性能。

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.

環境標準：圍擋護欄的施工應盡量減少對周圍環境的影響，比如降低施工噪音、減少粉塵揚塵等。需要遵守當地環境保護法律法規，配合相關部門的環境保護要求。

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.

綜上所述，圍擋護欄施工需要滿足、規范、美觀、品質和環境等多個方面的標準，以保證施工質量和使用效果。

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.
