4、注意事項(xiàng)

4. Precautions

1.成品護(hù)欄應(yīng)符合設(shè)計(jì)要求，經(jīng)驗(yàn)收合格后才能進(jìn)場施工。

1. The finished guardrail should meet the design requirements and can only be mobilized for construction after passing the acceptance inspection.

2.焊接點(diǎn)有打磨無法處理平整的及接口處有小孔的，需用原子灰密實(shí)以防進(jìn)水后生銹。

2. If the welding points are polished and cannot be processed smoothly, and there are small holes at the interface, atomic ash should be used to compact them to prevent rusting after water ingress.

3.連接部位需打磨光滑，刷兩道防銹漆，經(jīng)驗(yàn)收后再做表面一致處理。

3. The connecting parts need to be polished smooth, coated with two coats of rust resistant paint, and then subjected to surface consistency treatment after acceptance.

4.焊接時(shí)應(yīng)滿焊，禁止點(diǎn)焊。

4. During welding, full welding should be carried out and spot welding is prohibited.

5.已安裝完成的護(hù)欄上不得涂抹砂漿及掛放雜物。

5. The installed guardrail shall not be coated with mortar or hung with debris.

5、濟(jì)南鐵藝護(hù)欄質(zhì)量要求

1. The specifications, quality, and appearance of the finished guardrail meet the design requirements.

2.安裝位置、標(biāo)高正確，滿足設(shè)計(jì)要求。

2. The installation position and elevation are correct and meet the design requirements.

3.與預(yù)埋件連接牢固，無松動(dòng)、斷裂現(xiàn)象。

3. Connect firmly to the embedded parts without looseness or breakage.

4.護(hù)欄高度、護(hù)欄間距符合設(shè)計(jì)要求。

4. The height and spacing of guardrails meet the design requirements.

5.焊口平滑、焊縫均勻，且需經(jīng)過防銹處理。

5. The welding seam is smooth, the weld seam is uniform, and needs to undergo rust prevention treatment.

6、驗(yàn)收標(biāo)準(zhǔn)

6. Acceptance criteria

1.護(hù)欄的尺寸、高度、間距、油漆顏色符合設(shè)計(jì)要求。
