Joint connection method for concrete core wall and asphalt concrete core wall and filling device for concrete core wall and asphalt concrete core wall

The invention discloses a joint method for a concrete core wall and an asphalt concrete core wall and a filling device thereof. The joint method comprises the steps that the asphalt concrete core wall serves as an expanded section reinforced concrete core wall; an asphalt well with the diameter smaller than that of the reinforced concrete core wall is arranged at the end of the reinforced concrete core wall, and the asphalt well is filled with asphalt; and auxiliary seepage prevention measures such as contact clay are laid on the upstream face of the joint part. According to the concrete core wall and asphalt concrete core wall joint method and the filling device thereof, compared with a traditional construction method, the method has multiple technical advantages, the method can well adapt to the connection problem between an asphalt concrete core wall and a reinforced concrete core wall, the stability, reliability and repairability of an anti-seepage body are improved, and the construction period is shorten
