An annular boss 3 is provided on the inner cavity surface of the cavity, and a lower template 4 is placed on the upper surface of the annular boss 3. A plurality of anchor bolt positioning holes 5 are provided on both the upper template 2 and the lower template 4. Among the upper template 2 and the lower template 4, the corresponding anchor bolt positioning holes 5 are coaxially arranged to position the same anchor bolt 6.

[0032] In this embodiment, the main structure 1 is made of carbon structural steel, preferably made of Q235A carbon structural steel.

[0033] The main structure 1 adopts a frustum-shaped structure, and the area of its bottom end is larger than that of the top end. In this way, the main structure 1 is more stable when placed.

[0034] In this embodiment, the upper template 2 and the lower template 4 are also made of carbon structural steel, preferably made of Q235A carbon structural steel. The upper template 2 and the lower template 4 are both square templates. Correspondingly, the horizontal cross-section of the cavity also adopts a square matching the upper template 2 and the lower template 4.

[0035] As Figure 3 - Figure 4 shown in the figure, a positioning groove 7 is provided along the edge of the open top of the main structure 1. The upper template 2 is placed on the positioning groove 7. The edge of the upper template 2 contacts the bottom groove surface of the positioning groove 7. The upper template 2 is supported by the positioning groove 7 to realize the vertical positioning of the upper template 2. The side surface of the upper template 2 fits with the vertical side groove surface of the positioning groove 7 to realize the horizontal positioning of the upper template 2.

[0036] An annular boss 3 is provided at a set position on the inner cavity surface of the cavity. The lower template 4 is placed on the upper surface of the annular boss 3 and is supported by the annular boss 3 to realize vertical positioning.
