[0022] The working principle of the above technical solution is:
[0023] When No. 0 block 17 needs to be poured, first, the pouring formwork 1 is supported, so that the cavity formed inside after the support of several pouring formwork 1 is the specific structure and shape of No. 0 block 17, at this time, the internal blocking block 4 is arranged tightly against the inner wall of the pouring formwork 1, and the through hole 2 is blocked, then pouring operation is carried out, according to the different pouring depth, the vibrating rod 7 of corresponding depth is selected to extend to the inside of the pouring formwork 1 until the external blocking block 8 blocks the outer end of the through hole 2 to avoid the concrete from flowing out, after the vibrating rod 7 is deeply inserted into the pouring cavity, it is started to vibrate the poured concrete, so as to ensure the compactness of the poured concrete and improve the pouring effect of No. 0 block 17. After pouring is completed, the vibrating rod 7 is pulled outward, so that the internal blocking block 4 is reset. Of course, the number and height of the vibrating rod 7 can be set according to the size of No. 0 block 17.
[0024] In an implementable mode, one end of the through hole 2 arranged close to the internal blocking block 4 is provided with a counterbore 3, the diameter and height of the counterbore 3 match the internal blocking block 4, that is, the internal blocking block 4 is located in the counterbore 3 to block the through hole 2, that is, the internal blocking block 4 does not extend into the concrete, and the surface smoothness and effect of the No. 0 block 17 after the pouring is completed.
