As shown in fig. 1 and 2, the present embodiment provides a structure for draining water in a basement, which includes a bottom plate 1 and a waterproof layer 2. The bottom plate 1 is used as a base bottom plate of a basement. The waterproof layer 2 is disposed on the bottom side of the soleplate 1 for preventing groundwater from infiltrating into the soleplate 1. The bottom plate 1 and the waterproof layer 2 are both formed by pouring concrete. The bottom plate 1 is provided with a space for pouring a post-cast strip. Specifically, the middle part of the surface of the bottom plate 1 is concavely provided with a pouring space for forming a post-pouring belt. And after the bottom plate 1 is poured for a certain time, the post-pouring belt is poured and formed, so that cracks caused by uneven shrinkage in the solidification process of the bottom plate 1 are prevented.
A water stop plate 6 is embedded in the bottom plate 1, and the water stop plate 6 partially extends into a pouring space of the post-pouring belt. The two water stop plates 6 are arranged, the two water stop plates 6 are respectively positioned in the bottom plates 1 at two ends of the post-pouring strip in the width direction, and the two water stop plates 6 respectively penetrate through the corresponding side walls of the post-pouring strip. In order to realize a good waterproof effect, the water stop plate 6 extends along the length direction of the post-cast strip, and two ends of the water stop plate 6 respectively extend to two end faces of the length direction of the post-cast strip.
