All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0021] It should also be noted that, in the description of this application, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances. Example

[0022] This embodiment provides a method for constructing polyethylene sheets for water storage structures, which is characterized by comprising the following steps: (1) Material preparation: Preparation of polyethylene anchor nail 12: The anchor end of anchor nail 12 adopts fish bone spur 121 (refer to Figure 1 ), the bonding surface is flat.

[0023] Design layout: Arrange the steel bars and templates according to the design drawings, and design 12 anchor nail positions between the longitudinal and transverse steel bar gaps.

[0024] Formwork preparation: The formwork is made of wooden plywood, and the formwork is divided into blocks and numbered according to the size of the structure. The formwork of the curved water storage structure is pre-processed with the corresponding curved surface according to the corresponding curvature, and the formwork is laid out and numbered.

[0025] The anchor nails 12 and the template are fixed according to the designed drawings. The anchor nails 12 and the template are fixed with screws. A fixing screw is set at the center of each anchor nail 12. The screw fixing direction is tightened from the template side to facilitate removal when demolding later.

[0026] (2) Steel bar binding Place the rebars in the corresponding positions according to the design drawings. Use a steel ruler or other tool to measure the spacing between the rebars to ensure that they conform to the design layout. Tie the intersections of the rebars securely with steel wire or use spot welding to fix them.

[0027] (3) Concrete pouring Pouring of bottom slab concrete: After the bottom slab concrete is poured and before initial setting, the anchor nails 12 can be directly driven in with a rubber hammer according to the pre-designed anchor nail 12 spacing, and the top surface of the anchor nail 12 is kept flush with the concrete surface.

[0028] Concrete pouring for the side walls and roof: Start pouring the side walls and concrete from the bottom, layer by layer. Each layer should not exceed 500mm in thickness. Use an insert vibrator to ensure the concrete is compacted. During the vibrating process, insert the vibrator close to the outer formwork to prevent damage to the anchor pins 12. Concrete the roof from one end to the other, also in layers. After pouring, maintain a constant maintenance schedule. You can cover the concrete with plastic sheeting, sprinkle water, and other methods to keep the concrete surface moist.

[0029] (4) Template removal Before removing the formwork, remove the screws that fix the anchor nails 12. After all the fixing screws are removed, the formwork can be removed piece by piece. Remove the formwork piece by piece and layer by layer according to the principle of supporting first and then removing, and removing the last support first. Set up a warning area during the removal process to prevent unauthorized personnel from entering.

[0030] (5) Polyethylene plate connected to anchor nail 12 After construction is complete, measure the geometric dimensions of each water-facing surface of the reservoir structure. Design and cut the polyethylene sheets according to the measured dimensions. After finishing the wall surface, remove the dust film from the anchors 12 and install the polyethylene sheets according to the markings. The polyethylene sheets and anchors 12 can be connected by hot-melt welding or gluing. Install the polyethylene anchor sheets piece by piece until the entire tank interior is fully installed.

[0031] (6) Seam welding The welds between the polyethylene sheets are heat-melted using wire made of the same material. The welding temperature, pressure, and speed are adjusted according to the sheet thickness and other parameters. A hot melt machine is used during the construction process to ensure that the weld seams are full and prevent quality issues such as leaks and insufficient penetration.

[0032] The polyethylene board construction method for water storage structures of the present application adopts a pre-buried anchor nail 12 and a polyethylene board post-installation process, which can improve the shortcomings of the existing technology in which the polyethylene and anchor board are installed simultaneously, resulting in a large number of sealing holes in the anchor board in the later stage, causing great construction difficulty and easy formation of leakage points.

[0033] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
