[0020] The following is a detailed description of a concrete pump pipe fixing device provided by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent through the following description. It should be noted that the accompanying drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0021] Combine Figure 1 and Figure 2 As shown, the pump pipe 1 includes a horizontal pump pipe and a vertical pump pipe, and the vertical pump pipe at the bent portion is fixed by a concrete pump pipe fixing device. The concrete pump pipe fixing device provided in this embodiment includes a pump pipe fixing member 2, a connecting member 3, a spring assembly 4 and a bearing pier 5.

[0022] The pump pipe fixing 2 is a clamp with a rubber pad inside the clamp, which is tightened with an M20 hexagonal bolt to firmly fix the clamp to the vertical pump pipe. The clamp is provided with a connector, which can be an annular steel plate, which can be welded to the clamp.

[0023] The supporting pier 5 is made of reinforced concrete with a concrete strength of C30. A groove is provided on the side facing the pump pipe. The groove includes an end face and two or four sloped surfaces. For example, the supporting pier is 1000mm high, 700mm wide, and 565mm thick. The groove is 165mm deep, and the angle between the sloped surface and the end face is 135 degrees.
