电缆桥架安装的平整度检测需通过以下要点进行，确保安装质量符合规范要求：

　　The flatness inspection of cable tray installation should be carried out through the following points to ensure that the installation quality meets the specifications:

　　一、水平度检测

　　1、 Levelness detection

　　整体水平度

　　Overall levelness

　　使用精度0.02mm/m的框式水平仪，沿桥架全长测量，每10m取3个测点，水平偏差平均值≤3mm/m（总偏差≤15mm/10m）。例如10m长桥架总偏差≤20mm。

　　Using a frame level with an accuracy of 0.02mm/m, measure along the entire length of the bridge, taking 3 measuring points every 10m, with an average horizontal deviation of ≤ 3mm/m (total deviation ≤ 15mm/10m). For example, the total deviation of a 10m long bridge is ≤ 20mm.

　　局部调整

　　partial adjustment

　　若局部偏差超标，可在吊架与桥架间垫设0.5-2mm厚的薄钢板微调，多不超过3层，调整后需用螺栓紧固。

　　If the local deviation exceeds the standard, a thin steel plate with a thickness of 0.5-2mm can be placed between the hanger and the bridge for fine adjustment, with a maximum of 3 layers. After adjustment, it needs to be fastened with bolts.

　　二、垂直度检测

　　2、 Verticality detection

　　整体垂直度

　　Overall verticality

　　垂直桥架需用线锤或激光投线仪检测，垂直偏差≤3mm/m（10m高桥架总偏差≤30mm），确保无倾斜。

　　Vertical cable trays need to be inspected with a plumb bob or laser wire projector, with a vertical deviation of ≤ 3mm/m (total deviation of 10m high bridge frame ≤ 30mm), to ensure no tilting.

　　桥架连接处加装定位角钢或导向件，偏差超标时需重新校准或更换变形节段。

　　Install positioning angle steel or guide components at the connection of the bridge frame. If the deviation exceeds the standard, recalibration or replacement of the deformed section is required.

　　拼接处水平度

　　Levelness at the joint

　　桥架拼接时，用水平尺检测拼接面水平度偏差≤2mm，缝隙需均匀（≤1mm），防止电缆卡顿或绝缘层磨损。

　　When splicing cable trays, use a level ruler to check the levelness deviation of the splicing surface, which should be ≤ 2mm, and the gap should be uniform (≤ 1mm) to prevent cable jamming or insulation layer wear.

　　三、验收标准补充

　　3、 Supplementary acceptance criteria

　　外观检查

　　Visual inspection

　　目视检查桥架表面是否平整光滑，无明显划痕、凹陷或树脂脱落，颜色均匀。

　　Visually inspect the surface of the bridge for smoothness, no obvious scratches, dents, or resin peeling, and uniform color.

　　尺寸偏差

　　dimensional deviation

　　桥架与墙面/地面间距≥100mm，大跨度需加加强支撑。

　　The distance between the bridge and the wall/floor should be ≥ 100mm, and reinforcement support should be added for large spans.

　　连接件螺栓拧紧后外露丝扣≥2扣，防腐涂层无起皮、漏涂。

　　After tightening the connecting bolts, the exposed threads should be ≥ 2, and the anti-corrosion coating should not peel or be missed.

　　四、工具与方法

　　4、 Tools and Methods

　　水平仪 ：用于测量水平和垂直度，精度要求高。

　　Level gauge: used for measuring horizontal and vertical levels, with high precision requirements.

　　激光投线仪 ：辅助检测垂直度，尤其适用于高精度场景。

　　Laser projector: assists in detecting verticality, especially suitable for high-precision scenes.

　　塞尺 ：检测拼接缝隙宽度，确保≤0.5mm。

　　Feeler gauge: Check the width of the splicing gap to ensure it is ≤ 0.5mm.

　　通过以上检测方法，可评估电缆桥架安装的平整度及整体质量，确保符合GB50168等规范要求。

　　Through the above testing methods, the flatness and overall quality of cable tray installation can be comprehensively evaluated to ensure compliance with specifications such as GB50168.
