[0026] When using the concrete formwork with the leakproof slurry, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, bolts 4 are installed at the upper and lower ends of the first connecting rod 3, and nuts 5 are arranged on the outside of the bolts 4, a mounting hole 6 is arranged in the middle of the first connecting rod 3, and a first spring 7 is connected to the left side of the first connecting rod 3, and a handle 8 is connected to the right side of the first connecting rod 3, a sealing ring 10 is installed inside the second mounting groove 9, a connecting block 11 is arranged on the upper right end of the concrete formwork body 1, a second connecting rod 12 is installed inside the right side of the concrete formwork body 1, and a fixing pin 13 is fixed to the right end of the second connecting rod 12, firstly, the sealing ring 10 is installed inside the second mounting groove 9, and then another concrete formwork body 1 is installed on the right side of the concrete formwork body 1, so that the first mounting groove 2 on the left side of the concrete formwork body 1 fits with the outside of the sealing ring 10, and when the concrete formwork body 1 and the concrete formwork body 1 are fit and spliced, the fixing pin 13 is also driven to pass through the hole groove set on the left side wall of the other concrete formwork body 1, and through the mounting hole 6 in the middle of the first connecting rod 3, and the fixing pin 13 is fixed inside the second mounting groove 9. The first clamping block 15 and the second clamping block 16 are continuously fitted with the hole groove to squeeze the second spring 14 to shrink inward. When the fixing pin 13 moves to a certain position, the first clamping block 15 and the second clamping block 16 return to their original positions to stably splice the concrete formwork body 1 with the concrete formwork body 1. In order to ensure its stability, the connecting block 11 is installed at the upper and lower ends where the concrete formwork body 1 and the concrete formwork body 1 are connected. The first connecting rod 3 and the second connecting rod 12 are driven to slide left and right by pushing the handle 8, and the first connecting rod 3 and the second connecting rod 12 drive the bolt 4 to shrink toward the inner wall of the concrete formwork body 1 during movement.
