Tunnel type composite anchorage

The invention discloses a tunnel type composite anchorage and can effectively solve the problems of the strength and the rheological problems of a bridge location tunnel type anchorage with worse rock quality, and furthermore, the safety of tunnel cavitation is easily guaranteed. The tunnel type composite anchorage comprises a tunnel, an anchor plug body (21) and a front anchor room (22), wherein the anchor plug body (21) is formed by concrete which is filled and poured into the inner section of the tunnel; a rest pier (23) is arranged in the front anchor room (22); a main cable (10) is scattered by a rope scattering saddle at the top of the rest pier (23), and then, is anchored on the front anchor surface of the anchor plug body (21); anchor rods (31) which penetrate into a surrounding rock from the surface of a bedrock are distributed at the arch crown section and two side wall sections of the tunnel at intervals; a primary supporting structure and a secondary lining (35) are inwards arranged in sequence from the surface of the bedrock; a prestressed anchor rope (24) which penetrates through the anchor plug body (21) and the inner end surface of the tunnel and enters a deep rock mass is distributed and arranged along the axial direction of the tunnel; and two ends of the prestressed anchor rope (24) are fixedly connected with the front anchor surface of the anchor plug body (21) and the deep rock mass anchor respectively.
