[0034] A plurality of composite plates 11 are hoisted and assembled so that adjacent composite plates 11 are spaced apart from each other to form gaps 12, and then a connecting template structure 13 is installed at each gap 12; the connecting template structure 13 in this embodiment allows the gap 12 to be narrower, for example, it can be set to 50-100 cm; the steps of installing the connecting template structure 13 include: setting a bottom mold 14 below the gap 12, passing through the bottom mold 14 from bottom to top with a lower end screw 15 and then connecting to a conical connector 16 padded on the bottom mold 14, supporting a top mold 19 corresponding to the bottom mold 14 on the composite plate 11 through a sleeve 17 and a support screw 18, and then passing through the top mold 19 through an upper end screw 20 of a corresponding conical connector 16 and then connecting to the upper end of the conical connector 16; the bottom mold 14 can be a whole plate extending along the length of the gap 12, or it can be a plurality of closely overlapped plates; the top mold 19 can be a plurality of strip plates spaced along the length of the gap 12 and spanning the width of the gap 12.

[0035] A steel mesh 21 is tied to the composite plate 11, and the steel mesh 21 passes through the gap 12, that is, it is not broken at the gap 12;

[0036] Concrete 22 is poured on the composite plate 11 and fills the gap 12; the concrete 22 wraps the steel mesh 21 to form a reinforced concrete 22 body on the composite plate 11; the concrete 22 enters the gap 12 and is laid on the composite plate 11, thereby forming an integral structure of the composite plate 11, the steel mesh 21, and the concrete 22 body;

[0037] After the concrete 22 reaches a set strength, the connecting formwork structure 13 is removed, and grouting is injected into the sleeve 17 in the concrete 22 .

[0038] The anti-seepage construction method of the composite plate joints in the present scheme leaves a gap 12 between the composite plates 11, installs a connecting formwork structure 13 at the gap 12, and forms a reinforced concrete 22 structure on the composite plates 11 by tying steel bars and pouring concrete 22, which has the beneficial effect of convenient and quick construction. The connecting formwork structure 13 in the present scheme adopts the connection form of upper and lower end screws 15 and conical connecting parts 16 to reliably support the top form 19 and the bottom form 14.

The conical connector 16 is provided here, which increases the water flow line, makes the concrete casting surface form an integral whole, and does not produce holes penetrating the board surface after the mold is removed, avoiding leakage in the later stage.
