When two splicable prefabricated UHPC components are spliced, the two adjacent first splicing portions 102 and the second splicing portions 103 are surrounded to form a wet joint cavity 201, and UHPC slurry or other high-strength rubber is poured into the wet joint cavity 201 to achieve the splicing of the two splicable prefabricated UHPC components.

[0033] In the implementation manner of the present application, the splicable prefabricated UHPC component can have a variety of different structural forms:

[0034] See also Figure 1 , which is a first structural form of a splicable prefabricated UHPC component. The side wall 101 of the splicable prefabricated UHPC component 100a is a flat plate structure.

[0035] See also Figure 2-Figure 3 , which is the second structural form of the splicable prefabricated UHPC component. The side wall 101 of the splicable prefabricated UHPC component 100b / 100c is a folded plate structure, including a first side wall 101a and a second side wall 101b. The first side wall 101a and the second side wall 101b form an angle α, and α can be any angle between 0-180°. As an example, refer to Figure 2 When α=90°, the splicable prefabricated UHPC component 100b forms a right-angled corner component. Figure 3 When α=120°, the splicable prefabricated UHPC component 100c forms a corner component in the form of an obtuse angle.

[0036] See also Figure 4 In other embodiments, the spliced ​​prefabricated UHPC component 100c may also be an arc-shaped spliced ​​component.

[0037] By designing the splicable prefabricated UHPC components into different structural forms, the side wall structures of the water tank with different structural forms can be manufactured by splicing different splicable prefabricated UHPC components.

[0038] In addition, since the UHPC material has good anti-corrosion performance, the spliced ​​prefabricated UHPC component of this embodiment is also suitable for making the side wall structure of the sewage pool. Of course, the spliced ​​prefabricated UHPC component of this embodiment can also be used in other application scenarios, such as swimming pools or other side wall structures for accommodating objects.

[0039] See also Figure 8 , which is a water storage tank / sewage tank side wall structure formed by splicing a plurality of obtuse-angled prefabricated UHPC components 100c and a plurality of flat-plate prefabricated UHPC components 100a.

[0040] See also Fig. 9 , which is a square water storage tank / sewage tank side wall structure formed by splicing a plurality of right-angle splicable prefabricated UHPC components 100b and a plurality of flat-plate splicable prefabricated UHPC components 100a.

[0041] See also Fig.10 , which is a polygonal water tank / sewage tank side wall structure formed by splicing a plurality of obtuse-angled, splicable prefabricated UHPC components 100c.

[0042] See also Fig.11 , which is a circular water storage tank / sewage tank side wall structure formed by splicing a plurality of arc-shaped prefabricated UHPC components 100d that can be spliced ​​together.

[0043] Through the comprehensive utilization of components of different forms, other structural forms of water storage tanks / sewage tanks can be spliced ​​together to form side wall structures, such as elliptical shapes. Further, by increasing the number of splicable prefabricated UHPC components, water storage tanks / sewage tanks of different sizes can be spliced ​​together to meet the water storage requirements of different capacities.

[0044] See also Figure 5-Figure 7 , is a schematic diagram of the structure of the wet joint cavity 201 formed by the first joint portion 102 and the second joint portion 103 when two prefabricated UHPC components are joined. In order to form a flat structure on the outer surface of the side wall of the water storage tank, the first joint portion 102, the second joint portion 103 and the anti-seepage bottom plate 104 can all be convex toward the inner side of the water storage tank. In order to achieve the sealing of the slurry in the wet joint cavity 201, the mating surfaces of the first joint portion 102 and the second joint portion 103 should be ensured to fit tightly. Please refer to Figure 5 , is a form of cooperation between the first splicing part 102 and the second splicing part 103, a plane cooperation structure is set between the first splicing part 102 and the second splicing part 103, at this time, the first splicing part 102 and the second splicing part 103 have the same structure and are symmetrically arranged on both sides of the side wall 101. In other embodiments, in order to further improve the anti-permeability of the wet connection chamber 201, a matching anti-permeability structure can also be set between the first splicing part 102 and the second splicing part, please refer to Figure 6, is a form of the above-mentioned anti-permeation matching structure, a bevel matching structure is set between the first splicing part 102 and the second splicing part 103, and each matching plane of the first splicing part 102 and the second splicing part 103 is set as a bevel, which can not only improve the sealing performance and prevent the leakage of the slurry, but also facilitate demoulding. In other embodiments, the anti-permeation matching structure between the first splicing part 102 and the second splicing part 103 can also be set as follows Figure 7 The step groove matching structure shown can further improve the anti-leakage performance of the wet connection cavity 201.

[0045] It should be noted that, of course, other matching structures can be designed between the first joint portion 102 and the second joint portion 103 , as long as the anti-leakage property of the wet joint cavity 201 can be fully guaranteed.

[0046] In order to further improve the connection strength of the two spliced ​​prefabricated UHPC components, a horizontal tie rod 202 can be arranged between the first splicing part 102 and the second splicing part 103 before pouring the glue. The horizontal tie rod 202 plays a role during the pouring and installation to ensure that the first splicing part 102 and the second splicing part 103 are tightly fitted. In addition, a water-swelling waterproof glue can be laid on the matching plane 106 of the first splicing part 102 and the second splicing part 103 to further improve the anti-leakage performance.

[0047] In order to facilitate the demoulding of the splicable prefabricated UHPC component, the inner wall surfaces 105 and 107 of the first splicing portion 102 and the second splicing portion 103 may be provided with a draft angle.

[0048] See also Figure 12-14 The steps of making a water storage tank by using the splicable prefabricated UHPC components of this embodiment are as follows:

[0049] 1. Pour 20cm thick pool bottom concrete 301, which can be cantilevered 10cm in height.

[0050] 2. Prepare a plurality of spliceable prefabricated UHPC components (100a and 100b) according to the structural form and water storage capacity of the water storage tank, and splice the plurality of spliceable prefabricated UHPC components (100a and 100b) above the bottom concrete 301, ensuring that the first splicing parts 102 and the second splicing parts 103 of two adjacent spliceable prefabricated UHPC components are aligned and close to each other, so that they enclose and form a plurality of wet connection cavities 201;

[0051] 3. Pour UHPC slurry or high-strength rubber into the wet connection cavity 201 to ensure that the slurry fully fills the wet connection cavity 201;

[0052] 4. After the slurry solidifies, the various prefabricated UHPC components that can be spliced ​​are connected to form an integral water storage tank / sewage tank side wall structure;

[0053] 5. Cast slurry on top of the bottom sealing concrete 301 to form a bottom plate 302 so that the bottom plate 302 fills and covers the anti-seepage bottom plate 104.

[0054] See also Fig.14 In order to ensure the anti-leakage property of the water reservoir, the thickness D1 of the bottom plate 302 + the extension width L1 of the anti-seepage bottom plate 104 + the thickness D2 of the anti-seepage bottom plate 104 should be greater than or equal to 250 mm.

In addition, the protruding width D3 of the first splicing part 102 and the second splicing part 103 can be consistent with the extension width L1 of the anti-seepage bottom plate 104.

[0056] Due to the ultra-high performance of UHPC materials, the splicable prefabricated UHPC component of this embodiment can reduce the wall thickness and weight while ensuring strength. In addition, in order to further reduce the wall thickness or increase the strength, reinforcement can be provided in the transverse and / or longitudinal directions inside the splicable prefabricated UHPC component.
