step two: transversely placing a plurality of prefabricated drainage concrete modules (10) in a straight line to form a first module layer; when the drainage concrete formwork is placed, the lower bottom panel (5) is horizontally arranged, the inclined panel (11) faces the upstream face and aligns the hollows of the left and right adjacent drainage concrete formworks (10) to form a transverse drainage channel (2);
step three: filling a dam body (9) behind each vertical panel (3) in the first module layer, and enabling the connecting anchor bars (8) to be in anchoring connection with the dam body (9);
step four: when a filling dam body (9) is filled to the same height as the vertical panel (3), a plurality of drainage concrete modules (10) are continuously and transversely placed in a straight line on the upper portion of the first module layer to form a second module layer, a base panel (4) of each drainage concrete module (10) in the second module layer and an upper top panel (6) of each drainage concrete module (10) in the first module layer are placed in an up-and-down overlapping mode, and vertical drainage through holes (7) in the base panel (4) and the upper top panel (6) are aligned up and down to form a vertical drainage channel;
step five: repeating the step four until the dam body (9) reaches a preset elevation;
step six: and an impermeable layer (1) is laid on the inclined plane plate (11) of each module layer.
8. The method for constructing a dam made of low-plasticity concrete material according to claim 7, wherein the concrete method for prefabricating the drainage concrete module in the first step is as follows:
the first step is as follows: calculating an included angle a between the upper top panel (6) and the vertical panel (3) according to a preset slope ratio m of the upstream impermeable layer (1);
the second step is that: according to the technical scheme, the base panel (4) is horizontal, the vertical panel (3) is vertical to the base panel (4), the inclined panel (11) is arranged in an inclined mode, the bottom end of the inclined panel (11) is connected with the base panel (4) through the lower bottom panel (5), the top end of the inclined panel (11) is connected with the vertical panel (3) through the upper top panel (6), and the upper top panel (6) is parallel to the lower bottom panel (5); the included angle between the upper top panel (6) and the vertical panel (3) is set as the angle a calculated in the first step; vertical drainage through holes (7) which penetrate through the board surface from top to bottom are formed in the upper top board (6) and the lower bottom board (5) to carry out one-step forming cast-in-situ manufacturing, and an integral structure of the pentagonal drainage concrete module (10) with a hollow cross section is formed.
