为了配合荆江分洪南闸的加固设计 ,对 32孔闸门进行了在役结构安全检测。针对闸门的结构型式、运行特征 ,确定了有针对性的检测项目 ,包括外观检测、腐蚀状况检测、材料检测以及铰支座同轴度检测。根据不同检测项目采取了目测、现场测试、无损探伤等检测手段。在大量检测数据的基础上 ,对闸门金属结构的安全性和可靠性进行了评估。建议 :①除个别闸门需彻底更新外 ,大多数闸门可采用更换零部件和适当的加固措施。②针对闸门腐蚀状况 ,宜全部进行防腐涂装。③检出的第 15～ 16号传动轴粗晶缺陷指标超标 ,应予更换。④支铰轴座不同心度及单轴倾斜度超标 ,需对全部支铰轴重新安装测试。
In order to cooperate with the reinforcement design of the South Gate of Jingjiang Flood Diversion, the 32-hole gate was tested for safety in service. According to the structural style and operating characteristics of the gate, the targeted testing items including appearance inspection, corrosion status inspection, material testing and concentricity detection of hinged support were determined. According to different test items to take a visual test, field testing, non-destructive testing and other testing methods. On the basis of a large number of test data, the safety and reliability of gate metal structures were evaluated. Recommendations: ① In addition to the individual gate to be completely updated, most of the gate can be replaced with parts and appropriate reinforcement measures. ② for the gate corrosion, should be all anti-corrosion coating. ③ detected No. 15 ~ 16 drive shaft coarse grain defects exceeded, should be replaced. ④ branch hinge shaft seat of different concentricity and uniaxial inclination exceeded, the need to re-install all the test shaft hinge.
