This paper starts from the qiwan road anchor retaining wall slope protection system, this paper introduces the construction technology of anchor rod retaining wall, can be used for similar engineering construction engineering and technical personnel reference. Key words: anchor; retaining wall; construction; highway slope protection 1 Introduction Anchor retaining wall is a kind of retaining structure formed by bolt technique. Bolt is a new type of tension member, one end of which is connected with engineering structures, the other end of the drill hole, insert bolt, grouting and maintenance process in the stability of the anchorage formation, to inherit the earth pressure exerted on the structure of the thrust, thus the use of anchor bolt and formation to maintain structure the stable. As a light retaining structure, anchor retaining wall to replace the heavy masonry gravity retaining wall, can save a lot of masonry materials, has been widely used in highway, railway, coal and water retaining engineering, and has received very good effect. 2 Overview There are different forms of anchor retaining wall due to the differences of anchorage stratum, construction method, stress state and structure form. According to the structure of the wall, it can be divided into column, plate, anchor, retaining wall and plank type anchor rod retaining wall. Column plate anchor retaining wall is composed of retaining plate, ribs and anchor ribs is bearing retaining plate, bol
