The invention discloses an anchor pipe timber support and a timbering method. The timbering method includes the following steps: (a1) fixing the place on a slope for an anchor pipe timber support and setting aside a place for a construction platform through temporary brushing and filling; and (a2) constructing an anchor pipe timber support on the construction platform, including: (a21) boring a plurality rows of holes on the strong-strength layers with good stability in different angles on the construction platform, (a22) placing reinforcement ribs in the plurality rows of holes, (a23) injecting slurry in the plurality rows of holes in which the reinforcement ribs are placed to form a plurality rows of steel tube piles, and (a24) building a top beam for the timber support at the top partsof the plurality rows of steel tube piles and prearranging anchorage cable holes. The main body of the anchor pipe timber support can be constructed mechanically; the construction is quick, safe and reliable and cannot cause big damage to the environment; the construction plant is small and after the project is finished, the ecology can be recovered. In addition, the whole body of the anchor pipetimber support bears stress, so the anchor pipe timber support is more reasonable in stress strain and is more reliable.
