[0035] The following is in conjunction with the appendix Figure 1 -6 provides further detailed information about this application.

[0036] This application discloses a seepage-proof wall structure for water plant construction. (Refer to...) Figure 1 and Figure 2 The water plant construction seepage prevention wall structure includes a reinforced concrete wall 1 and a waterstop component 2.

[0037] Reference Figure 1 and Figure 2 A vertical steel mesh 13 is embedded in the reinforced concrete wall 1. The reinforced concrete wall 1 is divided into a first reinforced concrete wall 11 and a second reinforced concrete wall 12. The concrete of the first reinforced concrete wall 11 and the second reinforced concrete wall 12 are poured sequentially, resulting in an expansion joint 14 between the first reinforced concrete wall 11 and the second reinforced concrete wall 12. A waterstop 2 is embedded in the reinforced concrete wall 1, and the vertical projection of the waterstop 2 covers the expansion joint 14.

[0038] Reference Figure 1 and Figure 2 The water-stop component 2 includes a water-stop steel plate 21 and a water-swellable rubber plate 22. The water-stop steel plate 21 includes a corrugated section 211 and a straight section 212. There are two straight sections 212, which are located on both sides of the corrugated section 211. The vertical projection surface of the corrugated section 211 covers the expansion joint 14. The straight section 212 has mounting holes 2121, through which it is tied and fixed to the reinforcing mesh 13. That is, thin iron wires are passed through the mounting holes 2121 to tie and fix the reinforcing mesh 13 to the water-stop steel plate 21. The straight section 212 is tied and fixed to the vertically arranged reinforcing mesh 13 to ensure the verticality of the water-stop steel plate 21 and improve the installation accuracy of the water-stop steel plate 21. The water-stop steel plate 21 has good sealing properties, which allows water to penetrate along the expansion joint 14, thereby improving the self-proof water-seepage performance of the wall. The vertical projection of the wave segment 211 covers the expansion joint 14. The interlocking effect between the wave segment 211 and the concrete is greater, thereby improving the connection strength between the wave segment 211 and the concrete, reducing the gap between the waterstop steel plate 21 and the concrete, and improving the waterproof performance of the wall in the expansion joint 14 area.

[0039] Reference Figure 1 and Figure 2 Water-swellable rubber sheets 22 are fixed on both sides of the waterstop steel plate 21, and their vertical projection covers the expansion joint 14. When the reinforced concrete wall 1 is poured, the water-swellable rubber sheets 22 on both sides of the waterstop steel plate 21 will expand upon contact with water, allowing the waterstop 2 to come into close contact with the concrete, thereby improving the waterproofing performance of the wall in the expansion zone. At the same time, the water-swellable rubber sheets 22 have a certain deformation capacity, so when the first reinforced concrete wall 11 and the second reinforced concrete wall 12 undergo relative deformation due to temperature, foundation settlement, etc., the water-swellable rubber sheets 22 provide deformation space for the deformation of the first reinforced concrete wall 11 and the second reinforced concrete wall 12, thereby reducing the degree of structural damage to the reinforced concrete wall 1 caused by stress concentration.

[0040] Example 2

[0041] The difference between Example 2 and Example 1 is as follows:

[0042] Reference Figure 3 and Figure 4 The waterstop steel plate 21 has several connecting holes 231 for concrete to pass through. A clearance distance of not less than 8mm is provided between the connecting holes 231 and the expansion joint 14. By providing connecting holes 231 on the waterstop steel plate 21, the bonding strength between the waterstop steel plate 21 and the concrete is improved, thereby reducing the gap between the waterstop steel plate 21 and the concrete and enhancing the water-stopping effect of the waterstop steel plate 21.

[0043] Reference Figure 3 and Figure 4 Meanwhile, the water-stopping component 2 also includes several flow-dispersing rods 23 and spring components 24. Several flow-dispersing rods 23 and spring components 24 are provided, arranged vertically at intervals. The flow-dispersing rods 23 are fixed to the side of the water-facing side of the water-stopping steel plate 21, and a clearance gap is provided between the flow-dispersing rods 23 and the water-facing side of the reinforced concrete wall 1. One end of the spring component 24 is bonded or welded to the water-stopping steel plate 21, and the other end is welded or tied to the reinforcing mesh 13; a clearance gap is provided between the water-stopping steel plate 21 and the reinforcing mesh 13. When workers pour reinforced concrete wall 1, they can put the vibrating device against the waterstop steel plate 21. Under the action of the spring 24, the waterstop steel plate 21 and the baffle rod 23 vibrate to vibrate the concrete between the waterstop steel plate 21 and the water-facing formwork, thereby increasing the density of the concrete on the side of the waterstop steel plate 21 near the water-facing side and improving the self-waterproofing performance of the reinforced concrete wall 1.

[0044] Example 3

[0045] The difference between Example 3 and Example 1 is as follows:

[0046] Reference Figure 5 and Figure 6 The reinforced concrete wall 1 has a receiving groove 15 on its water-facing side. The receiving groove 15 is vertically arranged, and its vertical projection covers the expansion joint 14. The sidewall of the receiving groove 15 is coated with a waterproof coating layer 3. At least two layers of the waterproof coating layer 3 are provided along the direction away from the bottom wall of the receiving groove 15. In this embodiment, the waterproof coating layer 3 has three layers, and the waterproof coating layer 3 is made of polyurethane waterproof coating. Specifically, the worker first applies a red polyurethane waterproof coating, which solidifies to form the first waterproof coating layer 3. Next, a black polyurethane waterproof coating is applied, which solidifies to form the second waterproof coating layer 3. Finally, a white polyurethane waterproof coating is applied, which solidifies to form the third waterproof coating layer 3.

[0047] The implementation principle of a water plant engineering seepage-proof wall structure according to an embodiment of this application is as follows:

[0048] Reference Figure 5 and Figure 6 The three-layer waterproof coating 3 is applied using three different colors of polyurethane waterproof coating to ensure the number of coats of the waterproof coating 3, thereby ensuring the waterproof performance of the waterproof coating 3 and improving the water-proof performance of the wall.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
