The water stop screw is a structure which plays roles of stopping water, reinforcing and controlling templates, and is widely applied to construction of basement shear walls or civil air defense walls.

The water stop screw rod commonly used in the prior art comprises an inner rod provided with a water stop piece, two connecting pieces, two plugs and two outer rods. When the water stop screw is used, the water stop screw is firstly assembled together, then the water stop screw is assembled on a wall form according to a standard construction flow, and finally, the subsequent pouring work is carried out. After the wall pouring work is completed, the inner rod is left in the poured wall, so that the water stopping effect can be achieved, and the outer rod, the connector and the plug can be detached for subsequent reuse. However, the water stop screw in the prior art often has the following defects when in use:

(1) Inaccurate plug installation position

In the process of assembling the existing water stop screw, a limiting part for limiting the installation position of the plug is not available at present, the condition that the installation position of the plug is inaccurate easily occurs, when the water stop screw with the inaccurate installation position of the plug is assembled on a wall form and a wall body is poured, the plug cannot cover the hole of the wall form, which is inserted into the outer rod, and then liquid concrete flows out of a gap between the hole and the outer rod, so that the construction quality is seriously affected.

(2) Poor water-stopping effect

Only one water stop sheet is arranged on the inner rod of the existing water stop screw, and only one water stop sheet is arranged on the inner rod of the poured wall after construction is completed, so that the water stop effect is poor.

(3) Outer rod and plug are inconvenient to detach

After the wall pouring work is finished, the outer rod is usually directly rotated by hands when the outer rod needs to be disassembled, and time and labor are wasted. When the plug is required to be taken out, as the plug is positioned in the poured wall, the Bao Tiepian is usually inserted into a gap between the plug and the wall and the plug is pried out forcefully, and the plug is time-consuming, labor-consuming and easy to damage.
