In order to prevent the concrete pipe 700 with a longer length from occupying excessive space to affect construction, as a preferred embodiment of the present invention, as shown in fig. 10, a rolling type adaptor 600 is provided on the ground, a rolling roller 601 is installed on the rolling type adaptor 600, the concrete pipe 700 is wound on the rolling roller 601, and it is ensured that the wound portion of the concrete pipe 700 is not flattened, so that the delivery of concrete is not affected, and the messy concrete pipe 700 is tidied, thereby avoiding the occupation of excessive space.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
