On the other hand, the invention also provides a large-area concrete on-site water storage and maintenance method, and the large-area concrete on-site water storage and maintenance device comprises the following steps:

step one, after large-area concrete construction is completed, reasonably designing the using quantity of the water baffles according to the area of concrete curing, and connecting the water baffles through a plurality of middle columns and corner columns to form a rectangular frame. The water baffle, the middle column and the corner column are integrally connected with the EPDM waterproof rubber strip, so that the bottom of the maintenance device is closed. Then a water supply system is installed, and the water supply system is sequentially connected with a water storage tank, a water suction pump, a filter and a water inlet hole on the outer side of the water baffle through a water delivery pipe.

Step two, controlling a water inlet hole switch and a water outlet hole switch to open a water inlet hole and a water outlet hole, firstly ensuring that the water inlet hole switch at the water inlet hole connected with a water supply system is in an open state, and all other water inlet hole switches are in a closed state, and then opening all water outlet hole switches; the suction pump extracts a water source from the water storage tank, water is continuously injected into the water inlet hole through the filter, the filter is used for purifying water quality, one part of water flow injected into the water inlet hole enters the interior of each water baffle through the water through hole of the middle column and the water through hole of the corner column, and one part of water flow flows into the upper surface of the concrete to be maintained through the water outlet hole in the inner side of the water baffle. When the water storage height of the concrete curing area reaches a design value, the water level monitor transmits a signal to the water level controller and controls the water suction pump to stop water injection, the water inlet hole and the water outlet hole are closed (the water outlet hole switch and the water inlet hole switch connected with the water supply system can not be closed in the actual curing process so as to reduce the workload), and the water storage curing function of newly-poured concrete is realized. The inside water of breakwater is used for increasing concrete curing means's dead weight for thereby waterproof stripe compression deformation closely laminates with the concrete upper surface, prevents the rivers loss in the maintenance region.

And step three, in the process of water storage and maintenance of the concrete, the automatic water supplementing function is realized through the water level control assembly.
