核電站濟南電纜橋架安裝中存在的質(zhì)量問(wèn)題
1.1 橋架拼接點(diǎn)發(fā)生偏移
1.1 Bridge splice point offset
一般情況下,施工現場(chǎng)的環(huán)境的干擾性是影響橋架拼接點(diǎn)位置的關(guān)鍵因素之一,容易造成拼接點(diǎn)實(shí)現不了預期的規范要求,極易導致拼接點(diǎn)距離過(guò)大的情況出現。
In general, the interference of the construction site environment is one of the key factors affecting the position of bridge splice points, which can easily cause the splice points to fail to meet the expected regulatory requirements and easily lead to situations where the distance between splice points is too large.
1.2 錨固質(zhì)量不佳
1.2 Poor anchoring quality
對于電纜橋架安裝中的土建工程而言,錨固工藝仍然具有較大的不足,即使完成錨固板安裝之后,還是與具體過(guò)程進(jìn)展存在差距,難以真正保證橋架的穩定使用,在一定程度上制約著(zhù)土建工程的錨固質(zhì)量,嚴重影響著(zhù)電纜橋架安裝的合理性。
For civil engineering in cable tray installation, the anchoring process still has significant shortcomings. Even after completing the installation of the anchoring plate, there is still a gap with the specific process progress, making it difficult to truly ensure the stable use of the cable tray. This to some extent restricts the anchoring quality of civil engineering and seriously affects the rationality of cable tray installation.
1.3 電纜參數的失真性
1.3 Distortion of cable parameters
通常在安裝人員對濟南電纜橋架安裝工藝進(jìn)行檢查時(shí),往往會(huì )在橋架的電纜路徑間出現托盤(pán)跳躍以及功能標記出錯、數據不全等情況,在一定程度上影響著(zhù)橋架安裝的工程質(zhì)量。
Usually, when the installation personnel inspect the installation process of Jinan cable tray, there are often tray jumps, incorrect functional markings, and incomplete data between the cable paths of the tray, which to some extent affects the engineering quality of tray installation.
2 解決核電站電纜橋架安裝質(zhì)量問(wèn)題的途徑
Ways to solve the quality problems of cable tray installation in nuclear power plants
2.1 更改拼接點(diǎn)設計
2.1 Change splicing point design
針對橋架拼接點(diǎn)不合理的現狀,相關(guān)的核電站電纜橋架安裝企業(yè),要在實(shí)際的工程狀態(tài)的基礎上,對橋架安裝工作進(jìn)行二次安排,科學(xué)對拼接點(diǎn)的位置進(jìn)行合理規劃,并且進(jìn)行體現,貫徹落實(shí)工程的監督職能,對具體拼接點(diǎn)的安裝位置進(jìn)行有效管控,終實(shí)現合理的狀態(tài)。
In response to the current situation of unreasonable splicing points in cable trays, relevant nuclear power plant cable tray installation enterprises should make secondary arrangements for cable tray installation work based on the actual engineering status, scientifically plan and reflect the position of splicing points, implement the supervision function of the project, effectively control the installation position of specific splicing points, and ultimately achieve a reasonable state.
2.2 強化錨固控制
2.2 Strengthen anchoring control
若是遇到在核電站橋架電纜土建工程中發(fā)生錨固等問(wèn)題,需要有效依據橋架的實(shí)際安裝操作規范,對方鋼錨固的位置進(jìn)行移動(dòng),移動(dòng)偏離中心的位置上去,另一方面,還需要在相關(guān)的土建工程位置上焊接好方鋼,在配合好受力點(diǎn)的同時(shí),對土建錨固的受力點(diǎn)進(jìn)行調整,同時(shí)可以在連接螺栓的基礎上,對錨固板進(jìn)行二次安裝,對之前的土建錨固設計進(jìn)行再次的更改。
If there are anchoring and other issues encountered in the civil engineering of cable trays in nuclear power plants, it is necessary to effectively follow the actual installation operation specifications of the cable trays, move the position of the square steel anchoring to a position that is off center. On the other hand, it is also necessary to weld the square steel in the relevant civil engineering positions, adjust the force point of the civil anchoring while coordinating with the force point, and at the same time, install the anchoring plate again on the basis of connecting bolts, making changes to the previous civil anchoring design.
2.3 對電纜標識進(jìn)行監督
2.3 Supervision of cable identification
在核電站電纜橋架安裝的工程單位的實(shí)際工作中,需要嚴格依據相關(guān)的工程監理規范,強調對細節的檢查,強化監理的力度。與此同時(shí),在具體的施工階段內需要對電纜的標識進(jìn)行嚴格的檢查,保證濟南電纜橋架屬性、功能等相。
In the actual work of the engineering unit for the installation of cable trays in nuclear power plants, it is necessary to strictly follow the relevant engineering supervision standards, emphasize the inspection of details, and strengthen the supervision efforts. At the same time, strict inspection of cable identification is required during the specific construction stage to ensure the attributes, functions, and other aspects of Jinan cable tray.
