[0032] S2, positioning and laying out the guide wall steel bars according to the guide wall structure size, and installing the guide wall template 4 on both sides of the guide wall steel bars;

[0033] S3, adjust the length of the first limiting rod 31 inserted into the second limiting rod 32, so that the wooden squares 14 at the lower ends of the first supporting tube 11 and the second supporting tube 12 are connected to the guide wall template 4, and at the same time, the first supporting tube 11 and the second supporting tube 12 are respectively vertically connected to the first limiting rod 31 and the second limiting rod 32, and then the wooden squares 14 on the first supporting tube 11 and the second supporting tube 12 are respectively fixedly connected to the guide wall template 4, and the first limiting rod 31 and the second limiting rod 32 are fixedly connected by a latch;

[0035] S5, pouring and curing the guide wall concrete. Waterproof concrete should be used during the pouring process. The concrete should be fully vibrated to prevent honeycomb surface. After the pouring is completed, the concrete should be cured in accordance with the relevant requirements for waterproof concrete curing.

[0040] In order to solve the problem of water leakage when using traditional tension screws in guide walls in humid areas, and the lack of working surface for reinforcing the side formwork of the structural edge-sealed guide wall, and considering multiple factors such as construction efficiency, cost, and quality, a sleeve rod transmission openable and closable tool-type guide wall formwork system was invented. The specific principle of the installation of the guide wall side formwork is as follows:

[0041] 1. The entire formwork system is composed of square steel pipes as lateral reinforcement fixtures, with two angle irons welded on the side (the number of angle irons can be appropriately increased according to the actual casting conditions of guide walls of different sizes) supporting wooden squares and plywood as the side formwork of the precast guide wall.

[0042] 2. The side welded connection hinges of the square steel pipes on both sides are connected to each other through a limit mechanism, and the limit mechanism can be retracted to adjust the length so that the tool-type guide wall template system can adapt to guide walls of different widths;

[0043] 3. An adjustable sleeve rod is welded on the top of one side of the square steel pipe. When the length of the limit mechanism is adjusted and determined, the top sleeve rod is rotated to make the square steel pipes on both sides form a support to clamp the side form of the guide wall to be poured at the bottom, and tighten the formwork system as a whole.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
