Abstract: This application discloses a communication method and a related apparatus, and relates to the field of communication technologies. The method is applied to an SD-WAN overlay network. A CPE autonomously generates an SD-WAN overlay routing table, so that communication reliability and flexibility are improved. An RR specifies an overlay multicast RPF route to the CPE to implement SD-WAN overlay multicast communication, and the CPE does not need to perform path computation autonomously, so that a computing power requirement of the CPE is reduced. An identifier of the CPE and an identifier of a site are carried in a multicast join message to implement the SD-WAN overlay multicast communication. A standard IP header is carried in a multicast service packet to implement the SD-WAN overlay multicast communication, so that generalization, applicability, and compatibility are improved.

Abstract: A segmented grouting method for ramp drivage in an aquifer is provided. Concerning grouting reinforcement for a ramp in an aquifer, a grouting process is divided into four stages according to a pressure change, that is, micro-pressure filling, low-pressure diffusion, medium-pressure reinforcement, and high-pressure fracturing. In the micro-pressure filling, an initial pressure of a grouting orifice is 0, and a low-concentration single-component grout is used to fill an original fissure of the aquifer. In the low-pressure diffusion, a low-concentration bicomponent grout is used for grouting, the original fissure is expanded, and a grouting radius is increased. In the medium-pressure reinforcement, a high-concentration bicomponent grout is used for grouting, thereby reinforcing the aquifer. In the high-pressure fracturing, a high-concentration bicomponent grout is used to reinforce a new fractured fissure of the orifice caused by a high pressure and the original fissure, thereby forming a confining bed.
