In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example 1
Referring to fig. 1, fig. 2 and fig. 5, a water-swelling elongated accessory water-swelling strip [1] is formed by wrapping water-swelling powder or particulate matter (such as sodium polyacrylate, sodium methyl silicate, water-absorbing resin and the like) with a hydrophilic fabric or water-permeable membrane [2], as shown in fig. 1; the lower part and the middle-lower parts of the four sides of the water absorption expansion strip [1] are wrapped by a non-wetting film [4] (which is soft and can extend suitably) to form a water absorption expansion type surface waterproof strip [3] (the upper part or the same side of the two opposite side surfaces of the water absorption expansion strip [1] is exposed, and the exposed part is suitable for being contacted with waterproof surfaces on the two sides at least) as shown in figure 2; the method comprises the steps of processing the peripheral side surface or the side surface with a waterproof task of a waterproof board (7) with a waterproof function to form a continuous non-wetting surface (8), or processing more surfaces of the waterproof board (7) to form non-wetting surfaces, splicing the waterproof boards (7) together, installing water-absorbing expansion type surface waterproof strips (3) at the joints of the waterproof boards (1) and enabling the exposed parts of the water-absorbing expansion strips (1) to face upwards, as shown in figure 5, preferably enabling the side surfaces of the waterproof boards (7) and the water-absorbing expansion type surface waterproof strips (3) to be contacted tightly as much as possible, enabling the non-wetting surfaces to be well attached together after being installed, and improving the waterproof performance of the waterproof boards per se.
When water flows to the interface of the waterproof board [7], the water firstly contacts with the exposed part on the upper part of the water absorption expansion strip [1] and is absorbed and then is soaked into the water absorption expansion agent in the water absorption expansion strip [1], the water absorption expansion agent absorbs water and then expands, so that the non-wetting surface between the non-wetting surface [8] of the waterproof board [7] and the water absorption expansion type surface waterproof strip [3] is more tightly and uniformly bonded, and fine gaps formed between interfaces of the non-wetting surface during construction are filled and compacted, so that a longitudinally continuous and tightly bonded non-wetting surface is formed between the interfaces, the water leakage can be better prevented, the water cannot seep from the non-wetting film [4], and the waterproof task is completed.
