High-efficiency and energy-saving buried pipe used for ground source heat pump

The utility model discloses a high-efficiency and energy-saving buried pipe used for a ground source heat pump. The high-efficiency and energy-saving buried pipe comprises a circular pipe body, a wave-shaped surface is arranged on the outer wall of the circular pipe body in the circumferential direction. Touch arms are arranged on the inner wall of the circular pipe body. A heat preservation layer is paved on the inner wall, at the roots of the touch arms, of the circular pipe body. According to the high-efficiency and energy-saving buried pipe, the wave-shaped surface is arranged on the outer wall of the circular pipe body in the circumferential direction, the touch arms cover the inner wall, the contact area between the pipe and soil and the contact area between the pipe and liquid in the pipe are enlarged, intensity of the pipe is improved, at the same time, not only is heat exchange efficiency of the pipe improved, but also the heat preservation performance of the pipe is improved, heat loss is greatly re
