In order to reduce the tensile strain of the reverse arc section of the asphalt concrete panel, the asphalt concrete panel of the reservoir bank and the concrete of the drainage gallery are in straight line lap joint mostly, and the asphalt concrete panel of the dam and the concrete of the connecting plate are in reverse arc lap joint. Therefore, the straight line section and the reverse arc section of the asphalt concrete panel need to be transited through a connection structure.
Because the asphalt concrete panel needs to adapt to the deformation of the rock-fill dam, a reverse arc section is usually arranged to be connected with the connecting plate, and the tensile strain of the reverse arc section is larger. In order to ensure that the bank is in direct contact with the asphalt concrete panel of the dam, the reverse arc section is arranged on the asphalt concrete panel of the bank as much as possible during the previous design. However, the foundation of the asphalt concrete panel on the bank has small deformation, the filling body of the part provided with the reverse arc section is complex, the filling is thick, the construction surface is narrow, the construction quality is difficult to ensure, the reverse arc section often generates large deformation, the asphalt concrete panel is easy to crack and other defects, a centralized leakage channel is formed, and the safety of the dam is endangered.

The technical problem to be solved by the utility model is as follows: aiming at the problems, the connection structure of the straight line segment and the reverse arc segment of the asphalt concrete panel is provided.
The technical scheme adopted by the utility model is as follows: the utility model provides an asphalt concrete panel straight line section and linking structure of anti-segmental arc, has longer dislocation with asphalt concrete panel lapped reinforced concrete drainage corridor and reinforced concrete connecting plate on the plane, and asphalt concrete panel passes through straightway and reinforced concrete drainage corridor overlap joint, and asphalt concrete panel passes through anti-segmental arc and reinforced concrete connecting plate overlap joint, its characterized in that: a spacing groove is formed between the straight line section of the asphalt concrete panel and the reverse arc section of the asphalt concrete panel, a linking structure is arranged corresponding to the spacing groove, the upper surface of the linking structure is in lap joint with the reverse arc section of the asphalt concrete panel, the contact surface of the linking structure and the reverse arc section of the asphalt concrete panel is a reverse arc surface, and the bottom of the reverse arc surface is a reinforced concrete connecting plate.
And a circle of plastic water stopping filling groove is arranged on the periphery of the contact part of the connecting structure and the asphalt concrete panel, and plastic water stopping is filled in the groove.
The utility model has the beneficial effects that: according to the utility model, the connection structure is arranged, so that the asphalt concrete panel on the straight line section of the bank is well connected with the asphalt concrete panel on the reverse arc section of the dam, the problems of large strain caused by the reverse arc section arranged on the asphalt concrete panel on the bank and stress concentration caused by the direct connection of the straight line section and the reverse arc section are avoided, and the risk of generating cracks and other defects of the asphalt concrete panel due to concentrated stress can be effectively reduced. The connection structure is a whole pouring structure, is convenient to construct and high in safety guarantee, provides a channel led out through the dam body for the drainage gallery of the reservoir bank, is novel in arrangement, and has high engineering practical value.
