Concrete is poured to the designed height between the traditional structure rimstones in the herringbone framework foundation pit and the foundation pit, and cement mortar is poured to the designed height between the traditional structure rimstones in the herringbone framework foundation pit and the foundation pit and filled in a gap between two longitudinally adjacent rimstones. And curing and pouring concrete, removing the support die frame and the bottom edge template after the concrete is to be poured to a certain strength, and forming the one-time finished herringbone framework structure with the slope rimmed stones.

The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
