To study the mechanical performances of a new kind of overlapping connection with grouted anchor reinforcements in embedded metal corrugated pipes, a total of 24 groups of 72 specimens were prepared and tested. The overlap connection performance of grouting anchor reinforcements in embedded metal corrugated pipes was studied by bi-directional tension test. The factors such as the diameter of anchor reinforcements, anchor length and location of reinforcements were taken into account. The results show that the bi-directional tension test method can effectively reflect the actual stress state of the overlap connection. When the connection satisfies the structural requirements, the location of the reinforcement has little influence on the anchorage performance of the connection. Under the same conditions, the failure load of the specimens will increase with the increase of the diameter of reinforcements and the anchorage length. Meanwhile, under the same conditions, the average bond stress decreases with the increase of the reinforcement diameter and the anchorage length. Experimental results and analysis show that overlap connection with grout-filled anchor reinforcements in embedded metal corrugated pipe has good anchoring performances, and also has the advantages of simple structure and convenient construction.
