[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The casting mold provided by the present invention has the function of eliminating bubbles on the surface of the hydraulic concrete side wall. By arranging a density board on the inner side wall of the supporting formwork, on the one hand, the rigidity of the supporting formwork can be enhanced. On the other hand, since the density board is a porous material, it can absorb bubbles generated on the surface of the hydraulic concrete side wall during the casting process, thereby achieving the function of eliminating bubbles on the surface of the hydraulic concrete side wall and ensuring the durability and structural strength of the hydraulic concrete side wall. The positions of the supporting formwork and the density board are fixed by the baffle, steel bar clamping piece and locking nut located on the tension screw, and the outer side wall of the supporting formwork is reinforced by the steel bar clamping piece and the steel bar, thereby facilitating the casting and forming of the hydraulic concrete side wall.

[0017] 2. The casting mold provided by the utility model has the function of eliminating bubbles on the surface of the hydraulic concrete side wall. The steel bars are fixed by the combination of the steel bar groove of the clamping block and the arc groove of the T-shaped top block. When fixing the steel bars, the steel bars are placed in the arc groove, and the steel bars are fixed by squeezing the steel bars by the clamping block. During the fixing process, the steel bars squeeze the T-shaped top block to compress the compression spring. At the same time, the steel bars can be tightened by the T-shaped top block with the help of the reaction force of the compression spring. BRIEF DESCRIPTION OF THE DRAWINGS
