This invention provides a water-stopping device, relating to the field of building waterproofing technology. The water-stopping device includes a water-stopping steel plate and a drain pipe arranged along the length of the water-stopping steel plate. The drain pipe has a drain outlet along its length, allowing groundwater that has seeped onto the upper surface of the water-stopping steel plate to flow into the drain outlet. By installing this water-stopping device, the water-stopping steel plate can be used to seal the interface joint between pre- and post-cast concrete. If the water-stopping steel plate fails to stop the water flow, and the seeping groundwater flows from the interface joint between the water-stopping steel plate and the concrete to the upper surface of the water-stopping steel plate, the seeping groundwater will flow into the drain pipe through the drain outlet and then into a nearby sump. This prevents groundwater seeping through the concrete interface joint from leaking onto the basement floor surface, making the water-stopping device an integrated blocking and draining system with multiple lines of water-stopping defense, significantly improving the water-stopping effect at the post-cast concrete joint.
