Abstract: Disclosed are an alarm processing method and apparatus for solving the problem of the waste of resources caused by false detection of an LOF alarm. Specifically, a mechanism configured to detect an LOF pre-alarm is provided. A detection condition of an LOF pre-alarm is detecting that a framing failure lasts for a first duration; and a detection condition of an LOF alarm is detecting that the framing failure lasts for a second duration, wherein the second duration is less than the first duration. Upon detecting the LOF pre-alarm, a network device interpolates a first maintenance signal frame, wherein the first maintenance signal frame supports framing. That is, a network device that receives the first maintenance signal frame can perform normal framing, and does not report an alarm, for example, does not trigger the LOF alarm. Therefore, the network device that receives the first maintenance signal frame does not generate the LOF alarm by mistake because the framing failure lasts for the second duration, and does not report the LOF alarm or execute false switching, thereby avoiding the waste of resources.

Abstract: The present application relates to the technical field of underground structure construction, and specifically relates to an anti-floating anchor cable waterproof structure and a construction method therefor. The anti-floating anchor cable waterproof structure comprises: an anchor cable body, one end of which is buried in a cement grouting body and passes through a concrete cushion layer, a first waterproof coating layer and a first flexible waterproof layer from bottom to top; and a tension member, which is provided on the first flexible waterproof layer and applies a pressing force to the first flexible waterproof layer, wherein the anchor cable body passes through the tension member and is then locked. The first waterproof coating layer and the first flexible waterproof layer are arranged on the concrete cushion layer, and the rigid concrete cushion layer and the flexible first flexible waterproof layer are used in cooperation for waterproofing, which prevents water from leaking when there is a large gap between the concrete cushion layer and the anchor cable body caused by the loosening of the concrete cushion layer during the vertical stretching of the anchor cable body. Once the anchor cable body is stretched, the first flexible waterproof layer may still ensure a tight fit with the anchor cable body, thus ensuring that no groundwater will seep out along the anchor cable body.
