[0002] With the increasing global demand for clean energy, wind power has been widely adopted as an important renewable energy source. Calculations show a strong correlation between wind turbine tower height and power generation; in central China, increasing the tower height from 100 meters to 140 meters can increase annual power generation by more than 15%. To economically increase tower height, existing technologies have proposed prefabricated concrete composite tower structures, such as... Figure 4 As shown, the prefabricated concrete composite tower structure employs segmental assembly construction. Each segment is divided into multiple tube segments, which are circumferentially connected by bent bolts, which are installed inside circumferential connection holes. The segments are connected via flange holes, and prestressed anchor cables are also installed along the entire tower. However, these tube segments are relatively large, with some exceeding 10 meters in diameter, while the assembly accuracy requirement is ±1mm, making their fabrication extremely challenging.

Detailed Implementation

[0028] like Figure 1 , 3 As shown, a prefabricated concrete composite tower segment mold includes an integral bottom mold and a multi-piece top mold. Liquid-passing pipes are provided on the bottom mold and the top mold to control the temperature of the segment mold to a preset temperature by passing liquid through them. At the same time, the temperature of the construction site is also controlled to a preset temperature.

[0029] The bottom mold includes a bottom mold surface, and a bottom mold grid is provided on the back side of the bottom mold surface; the top mold includes a top mold surface, and a top mold grid is provided on the back side of the top mold surface.

[0030] Multiple first liquid inlet pipes are positioned near the bottom and top mold surfaces. The ends of these first liquid inlet pipes connect to connecting hoses, which are used to connect to liquid supply and temperature control devices. This structure allows for the regulation of the entire mold temperature by introducing liquid, such as water, into the liquid inlet pipes. Temperature control is maintained throughout the entire mold-setting and casting process to ensure that the dimensions of the produced pipe segments remain consistent with the dimensions of the pipe segments used in the final on-site construction.

[0031] Example 2:

[0032] The bottom mold includes a bottom mold surface, and a bottom mold grid is provided on the back side of the bottom mold surface;

[0033] The top mold includes a top mold surface, and a top mold grid is provided on the back side of the top mold surface;

[0034] Preferred solutions include Figure 1 , 2 In this structure, multiple isothermal plates are fitted together on the bottom and top mold surfaces. The isothermal plates are made of copper, aluminum, or carbon steel. A second liquid-passing pipe is installed inside the isothermal plate, and the second liquid-passing pipe is connected to a connecting hose via a connector. The connecting hose is used to connect to the liquid supply and temperature control device. This structure allows for better and more uniform temperature diffusion.

[0035] An insulation layer is also provided on the side of the isothermal plate away from the bottom and top mold surfaces. This structure can control the temperature while reducing energy consumption.

[0036] Example 3:

[0037] In the preferred embodiment, multiple temperature sensors are also provided on the mold;

[0038] In a preferred embodiment, temperature sensors are installed at the inlet and outlet of the liquid inlet pipe. This structure allows for feedback on the mold temperature, or further adjustment of the mold temperature based on water temperature feedback.

[0039] Example 4:

[0040] Side molds are fixed on both sides of the bottom mold, protruding above the bottom mold surface to limit the height of the tunnel lining segments. Adjustable side molds are located at both ends within the side molds, with side mold bases at both ends. These side mold bases are connected to the bottom mold bases via side mold screws, allowing for precise adjustment of the side mold positions. This adjustable side mold design improves mold precision. The precision control of this invention reaches 0.02mm. The final assembly precision reaches ±0.5mm, lower than the project's precision requirements, significantly improving the efficiency of on-site assembly and construction.

[0041] A positioning step is provided on the top of the side mold, and a corresponding step is provided on the edge of the top mold to achieve precise positioning of the top mold. The top mold and the side mold are connected by screws. This structure facilitates precise positioning.
