Therefore, a sewage collecting tank, a sewage treatment tank, an initial rainwater tank, a fire-fighting water tank designed for fire fighting and the like need to be built, and if the construction quality of the above water tanks cannot be guaranteed, the consequences are very serious.

The existing foam board is easy to cause slurry leakage and displacement of the foam board due to the characteristics of low strength and poor stability, the slurry leakage of the foam board can cause the expansion joint to be grouted to influence the expansion and contraction of the water pool, the displacement of the foam board can cause the thickness of the reinforcing steel bar protective layer to be different, the protective effect of the reinforcing steel bar is reduced, and the service life of the water pool is reduced. Compared with the original foam board, the construction process of the foam sandwich board is unchanged, raw materials and proportion do not need to be adjusted, only the adjustable fixed steel plate of the foam sandwich board is added, so that the thickness of the steel bar protection layer of the reinforced concrete pool is unchanged, and the strength stability of the foam sandwich board and the sealing degree between the boards are far higher than those of the foam board. Finally, the construction speed and the engineering quality of various pool projects are improved, and the economic benefit and the social benefit are obviously improved.

However, the existing foam sandwich plate is applied to the construction process of the double-wall expansion joint of the large-scale pool, the foam sandwich plate cannot be adjusted and fixed, and the protection effect on the foam sandwich plate is low.
