1.1 橋架拼接點(dian)發(fa)生偏(pian)移

1.1 Bridge splice point offset

壹(yi)般(ban)情況(kuang)下(xia)，施(shi)工現場(chang)的環(huan)境(jing)的幹擾性(xing)是影響(xiang)橋架拼接點(dian)位置(zhi)的關(guan)鍵(jian)因(yin)素(su)之(zhi)壹(yi)，容(rong)易造(zao)成(cheng)拼接點(dian)實現不(bu)了(le)預(yu)期(qi)的規(gui)範(fan)要求，極易(yi)導(dao)致拼(pin)接(jie)點(dian)距離(li)過大(da)的情(qing)況(kuang)出(chu)現(xian)。

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(gu)質(zhi)量(liang)不(bu)佳(jia)

1.2 Poor anchoring quality

對於(yu)電(dian)纜橋架安裝(zhuang)中的土(tu)建工(gong)程(cheng)而(er)言(yan)，錨(mao)固(gu)工藝(yi)仍(reng)然(ran)具(ju)有較大(da)的不(bu)足(zu)，即(ji)使(shi)完成(cheng)錨(mao)固(gu)板(ban)安裝(zhuang)之後(hou)，還是與具(ju)體過程(cheng)進(jin)展存在差距，難(nan)以真(zhen)正保證橋架的穩(wen)定使(shi)用(yong)，在(zai)壹(yi)定程(cheng)度上制(zhi)約著(zhe)土(tu)建工(gong)程(cheng)的錨(mao)固(gu)質(zhi)量(liang)，嚴(yan)重(zhong)影響(xiang)著(zhe)電(dian)纜橋架安裝(zhuang)的合理性(xing)。

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(dian)纜參數(shu)的失(shi)真(zhen)性(xing)

1.3 Distortion of cable parameters

通常在(zai)安裝(zhuang)人(ren)員(yuan)對濟南(nan)電(dian)纜橋架安裝(zhuang)工藝(yi)進(jin)行檢(jian)查時(shi)，往(wang)往(wang)會在(zai)橋架的電(dian)纜路徑間(jian)出(chu)現托盤跳躍(yue)以(yi)及功能(neng)標記(ji)出錯、數據(ju)不全等(deng)情況(kuang)，在(zai)壹(yi)定程(cheng)度上影響(xiang)著(zhe)橋架安裝(zhuang)的工(gong)程(cheng)質(zhi)量(liang)。

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(he)電(dian)站電(dian)纜橋架安裝(zhuang)質(zhi)量(liang)問(wen)題的途(tu)徑

Ways to solve the quality problems of cable tray installation in nuclear power plants

2.1 更(geng)改(gai)拼(pin)接(jie)點(dian)設計(ji)

2.1 Change splicing point design

針(zhen)對橋架拼接點(dian)不合理的現(xian)狀，相關(guan)的核(he)電(dian)站電(dian)纜橋架安裝(zhuang)企業(ye)，要在實際的工(gong)程(cheng)狀態的基礎上，對橋架安裝(zhuang)工作(zuo)進(jin)行二(er)次(ci)安排(pai)，科(ke)學(xue)對拼(pin)接(jie)點(dian)的位置(zhi)進(jin)行合理規(gui)劃(hua)，並且(qie)進(jin)行體現(xian)，貫徹(che)落(luo)實工程(cheng)的監(jian)督職(zhi)能(neng)，對具(ju)體拼(pin)接(jie)點(dian)的安裝(zhuang)位置(zhi)進(jin)行有效(xiao)管控(kong)，終(zhong)實現合理的狀態。

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(qiang)化(hua)錨(mao)固(gu)控制(zhi)

2.2 Strengthen anchoring control

若(ruo)是遇(yu)到在(zai)核(he)電(dian)站橋架電(dian)纜土(tu)建工(gong)程(cheng)中發(fa)生錨(mao)固(gu)等問(wen)題，需(xu)要有效(xiao)依據橋架的實際安裝(zhuang)操作(zuo)規範，對方(fang)鋼(gang)錨固(gu)的位置(zhi)進(jin)行移動，移動偏(pian)離(li)中心(xin)的位置(zhi)上去，另壹(yi)方(fang)面(mian)，還(hai)需(xu)要在相關(guan)的土(tu)建工(gong)程(cheng)位置(zhi)上焊(han)接好(hao)方鋼(gang)，在(zai)配合好(hao)受(shou)力點(dian)的同(tong)時(shi)，對土(tu)建錨(mao)固(gu)的受(shou)力點(dian)進(jin)行調整，同(tong)時(shi)可(ke)以(yi)在(zai)連接螺栓(shuan)的基礎上，對錨(mao)固(gu)板(ban)進(jin)行二(er)次(ci)安裝(zhuang)，對之(zhi)前(qian)的土(tu)建錨(mao)固(gu)設計(ji)進(jin)行再次(ci)的更(geng)改(gai)。

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(dian)纜標識(shi)進(jin)行監(jian)督

2.3 Supervision of cable identification

在(zai)核(he)電(dian)站電(dian)纜橋架安裝(zhuang)的工(gong)程(cheng)單(dan)位的實際工(gong)作中，需要嚴(yan)格(ge)依據相關(guan)的工(gong)程(cheng)監(jian)理規(gui)範(fan)，強(qiang)調(tiao)對細(xi)節(jie)的檢(jian)查，強(qiang)化(hua)監(jian)理的力(li)度。與(yu)此(ci)同(tong)時(shi)，在具(ju)體的施(shi)工(gong)階段(duan)內需要對電(dian)纜的標(biao)識(shi)進(jin)行嚴(yan)格(ge)的檢(jian)查，保證濟南(nan)電(dian)纜橋架屬(shu)性(xing)、功能(neng)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.
