Pile splicing formwork

The invention discloses a pile splicing formwork. The pile splicing formwork comprises a barrel made of an arc coiled material. The barrel is provided with an opening. First connecting through holes formed in the height direction are formed in one end of the position of the opening of the barrel. A plurality of rows of second connecting threaded holes corresponding to the first connecting through holes are formed in the other end of the position of the opening of the barrel. A pouring opening and a vibration hole are formed in the barrel in the lateral direction. L-shaped plates are fixed to the two sides of the position of the pouring opening. A lateral inserting groove with an upward opening and an inward opening is defined by each L-shaped plate and the barrel. A supporting plate is fixed to the lower side of the position of the pouring opening. The pouring opening is provided with a pouring hopper and a closed plate. The pouring hopper comprises a bottom plate and a side plate. An inserting plate bent outwards is arranged at the tail of the side plate. The bottom end of the bottom plate is in an arc shape matched with the radian of the side wall of the barrel. The inserting plate of the pouring hopper is inserted in the lateral inserting grooves from top to bottom and is directly led to the supporting plate. The bottom plate of the pouring hopper is located below the pouring opening and is closely attached to the barrel. The closed plate is matched with the side wall of the barrel in radian. According to the pile splicing formwork, a middle damaged pile can be repaired more rapidly and firmly.
