Background
The water stop screw is usually used for pouring of the shear wall of the basement, and has the functions of fixing the template and controlling the pouring thickness of concrete. Compared with the common wall-through screw, the difference is that 1, a water stop sheet is arranged in the middle of the water stop screw; 2. when the formwork is removed, the common wall-penetrating screw rod is integrally pulled out for repeated use, and the middle section of the water-stopping screw rod is left on the wall body after the two ends of the wall are sawn off, so that the water impermeability of the wall body is ensured.
In the past, in engineering projects such as basements, sewage ponds, water storage ponds and the like constructed all over the country, a construction method that a hole is drilled in a template and a water stop screw rod penetrates through the template is adopted for installing the template. After the template is drilled, 6-9 holes are drilled on the standard clamping plate surface 915 multiplied by 1830 of each plate; after the template is drilled, if the disassembled template is used as a shear wall template or a floor template of an above-ground project for repeated use, on one hand, the original drilled holes leak slurry when the concrete is tamped, which affects the concrete structure and the appearance of the concrete, and the repeated use frequency is only 50-60% of that of the un-drilled plate, which seriously affects the repeated use quality of the template, and relatively increases the project cost; in addition, the water stop ring is arranged in the middle of the water stop screw rod of the underground engineering, the screw rod is very difficult to penetrate when the template is installed, and the template is difficult to detach due to the fact that each template is penetrated by 6-9 screw rods, so that labor is wasted, the workload of workers is greatly increased, and the construction period of the underground engineering is prolonged.
