The utility model discloses a three-section type energy-saving water stop screw rod. The three-section type energy-saving water stop screw is composed of a connecting screw with a screw thread, a connecting sleeve with a water stop piece and a PVC plastic pipe. After the concrete is poured and formed, the connecting screw rod with the screw threads at the two ends is detached, and then the two ends of the connecting sleeve with the water stop strip are filled with micro-expansion cement mortar for sealing. The method is simple and fast to operate, and the engineering quality is easy to guarantee. Meanwhile, recycling of the connecting screw rod with the screw thread is achieved, cost is saved, and recycling of resources is achieved. 本实用新型公开了一种三段式节能型止水螺杆；三段式节能型止水螺杆由带丝扣的连接螺杆、带止水片的连接套筒和PVC塑料管三部分组成。待混凝土浇筑成型后，将两端带丝扣的连接螺杆拆掉，然后将带止水片的连接套两端灌入微膨胀的水泥砂浆进行密封。该种方式操作简便快捷，且易于保证工程质量。同时还实现了带丝扣的连接螺杆再利用，既节约成本，还实现了资源的再利用。
