Description

Technical Field

[0001] The utility model relates to water conservancy projects, in particular to a double-layer water-stopping structure used for hydraulic structures. Background Art

[0002] Anti-seepage measures are an important part of water conservancy projects. In order to reduce the infiltration damage of adjacent structures, water-stop structures are often installed between the structures of hydraulic structures to form a continuous and closed water-stop system. At present, the commonly used water-stop parts in water conservancy projects mainly include copper sheets, rubber waterstops and plastic waterstops. Copper sheets have the best anti-seepage performance, strong deformation adaptability, and are not easy to rust and break; rubber waterstops and plastic waterstops can generally withstand a hydrostatic pressure equivalent to a 20m head, and have good elasticity and toughness, and have a good anti-seepage effect, but when the uneven settlement of the foundation is large, measures must be taken to prevent it from breaking.

[0003] With the increasing importance of projects and the increasing grade of buildings, the requirements for anti-seepage are also getting higher and higher. Double-layer waterstops are usually used in important parts such as dams and lock chambers to ensure anti-seepage effects. In order to meet different structural requirements, double-layer waterstops can be made of different materials, such as a copper sheet waterstop plus a rubber waterstop, or the same materials can be used, such as two copper sheet waterstops. However, the connection treatment of double-layer waterstops is still the focus of engineering design and construction, especially the waterstop connection problems at the intersection of vertical waterstops and horizontal waterstops, and between horizontal waterstops. There are common anti-seepage problems at the joints of existing double-layer waterstop materials, which is still one of the pain points that need to be solved. Summary of the invention

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] Implementation Method 1

[0029] Combination Figure 1-5 It can be seen that this embodiment provides a double-layer water-stop structure for hydraulic structures, including a first water-stop member (i.e., a first rubber water-stop strip 1), an upper water-stop unit parallel to the first rubber water-stop strip 1, and a second water-stop member (i.e., a second water-stop copper sheet 2) connecting the first rubber water-stop strip 1 and the upper water-stop unit together, and the spacing between the first rubber water-stop strip 1 and the upper water-stop unit is controlled to be 150 mm to 250 mm;

[0030] The thickness of the second water-stop copper sheet 2 is 0.8-1.4 mm, the height of the second nose 2.1 in the middle is 30 mm-90 mm, and the width of the second nose 2.1 is 20 mm-30 mm; the width of the second wing plate 2.2 is 150 mm-250 mm, and the height of the second flange 2.3 is consistent with the height of the nose;

[0031] The second waterstop copper sheet 2 is fixedly connected to the first rubber waterstop 1 through a first connecting structure. The first connecting structure includes a first connecting sheet 3 fixedly connected to the bottom of the second waterstop copper sheet 2 and a first pressing sheet 4 arranged on the lower side of the first rubber waterstop 1. The first pressing sheet 4, the first rubber waterstop 1 and the first connecting sheet 3 are fixed together by rivets or bolts, and the first connecting sheet 3 and the first pressing sheet 4 are both glued to the first rubber waterstop 1, effectively ensuring a reliable connection between the waterstop copper sheet and the rubber waterstop.

[0032] During actual installation, the lower part of the second water-stop copper sheet 2 can be horizontally bent and the nose part and the flange part of the bent part can be cut off to obtain the first connecting sheet 3. The first connecting sheet 3 and the second water-stop copper sheet 2 are an integrated structure, which effectively ensures the anti-seepage performance between the first rubber waterstop belt 1 and the second water-stop copper sheet 2.

[0033] Combination Figure 1 and6 It can be seen that the upper water-stop unit includes a pair of third water-stop parts (i.e., the third water-stop copper sheet 5), and the connecting end of each third water-stop copper sheet 5 has a second connecting sheet 6 extending vertically upward, and the two second connecting sheets 6 are respectively welded on both sides of the second water-stop copper sheet 2 and the two second connecting sheets 6 are fixedly connected by rivets to ensure reliable connection; the space enclosed by the first rubber water-stop belt 1, the second water-stop copper sheet 2 and the third water-stop copper sheet 5 is filled with foam board, and the four sides of the foam board are densely filled with foam glue, and the outside is sealed with sealant to improve the anti-seepage performance.

[0034] The first rubber waterstop 1 is preferably a center hole type rubber waterstop with a thickness of 6 mm to 12 mm, an outer diameter of the center hole r=10 mm to 15 mm, and a length of the wing plates on both sides of 150 to 250 mm.

[0035] The third water-stop copper sheet 5 is a W-shaped water-stop copper sheet with a thickness of 0.8-1.4 mm. The height of the third nose 5.1 is 30 mm-90 mm, and the width of the third nose 5.1 is 20 mm-30 mm. The width of the third wing plate 5.2 is 150 mm-250 mm. The height of the third flange 5.3 is consistent with the height of the nose. The third flange 5.3 and the third nose 5.1 are located on both sides of the third wing plate 5.2. Figure 2 .

[0036] During actual processing, the connecting end of each third water-stop copper sheet 5 can be folded vertically upwards and the nose of the folded part can be cut off to obtain the second connecting sheet 6. The second connecting sheet 6 is welded to the second wing plate of the second water-stop copper sheet 2, and the second nose 2.1 of the second water-stop copper sheet 2 and the third nose 5.1 of the third water-stop copper sheet 5 are welded together. This not only ensures a reliable connection, but also ensures the water-stopping effect. It can also be processed in a factory, reducing the amount of on-site welding work, ensuring welding quality, reducing the frequency and duration of later manual maintenance, and further improving the water-stopping effect.

[0037] The utility model standardizes the connection between the water-stop rubber belt and the water-stop copper sheet, and also standardizes the connection between the horizontal water-stop copper sheet and the vertical water-stop copper sheet. The connection is reliable and has good anti-seepage effect, and has important application value.

[0038] Implementation Method 2

[0039] The difference between this embodiment and the first embodiment is that the double-layer water-stop structure described in this embodiment further includes a fourth water-stop member (i.e., a fourth rubber water-stop strip 7), the upper water-stop unit further includes a water-stop strip 8 connecting the second water-stop copper sheet 2 and the fourth rubber water-stop strip 7 together, the fourth rubber water-stop strip 7 is arranged in parallel with the second water-stop copper sheet 2, and the fourth rubber water-stop strip 7 is perpendicular to the first rubber water-stop strip 1, see Figure 7Among them, the bottom of the fourth rubber water stop 7 and the first rubber water stop 1 are connected by vulcanization, see Figure 8 .

[0040] Combination Figure 9-10 It can be seen that the waterstop plate 8 adopts a waterstop copper plate with the same structure as the third waterstop copper plate 5. The two ends of the waterstop plate 8 are folded vertically upward and the nose of the folded section is cut off to form a third connecting plate 9. One of the third connecting plates 9 is welded to the second waterstop copper plate 2, and one of the third waterstop copper plates 5 is welded to the outside of the second waterstop copper plate 2; the other third waterstop copper plate 5 is located on the outside of the fourth rubber waterstop belt 7, and the second connecting plate 6, the fourth rubber waterstop belt 7 and the other third connecting plate 9 of the waterstop plate 8 are fixed together by rivets, and there is an adhesive layer between the second connecting plate 6 and the fourth rubber waterstop belt 7, and between the third connecting plate 9 and the fourth rubber waterstop belt 7, which further ensures the reliable connection between the fourth rubber waterstop belt 7 and the horizontally arranged waterstop copper plate.

[0041] The space enclosed by the first rubber water stop strip 1, the second water stop copper sheet 2, the fourth rubber water stop strip 7 and the water stop sheet 8 is filled with a foam board, the surroundings of the foam board are densely filled with foam glue, and the outside is sealed with sealant to further ensure the water stop effect at the gap. Figure 7 .

[0042] In this embodiment, the fourth rubber waterstop 7 is a center hole type rubber waterstop with a thickness of 6 mm to 12 mm, a center hole outer diameter r=10 mm to 15 mm, and a wing plate length of 150 to 250 mm.

[0043] This embodiment adopts two horizontal waterstops and two vertical waterstops, which not only standardizes the connection between the horizontal waterstop rubber belt and the vertical waterstop copper sheet, but also standardizes the connection between the horizontal waterstop copper sheet and the vertical waterstop copper sheet, and also standardizes the connection between the horizontal waterstop copper sheet and the vertical rubber waterstop belt. It can ensure the reliable connection of each connection part and the anti-seepage effect of the connection part. It can be processed in the factory to ensure the welding quality, and it can also reduce the amount of on-site welding work, reduce the frequency and period of later manual maintenance, and further improve the waterstop effect.

[0044] Of course, in actual engineering, only one horizontal waterstop + two vertical waterstop double-layer structure can be used. The horizontal waterstop can also be a waterstop copper sheet F1. The bottom of the vertical waterstop copper sheet F2 is folded vertically and the nose is cut off. Then, it is welded to the horizontal waterstop copper sheet F2 to achieve the connection between the two. The ends of the two horizontal waterstop copper sheets F2 are folded vertically upward and then fixedly connected with the vertical rubber waterstop strip F3 (the rubber waterstop strip F3 can also be replaced by a waterstop copper sheet). For details, see Fig.11 .

[0045] The utility model standardizes the connection between waterstop copper sheets and waterstop copper sheets, the connection between vertical waterstop copper sheets and horizontal rubber waterstop strips, and the connection between vertical rubber waterstop strips and horizontal waterstop copper sheets. It can not only ensure the reliable connection and anti-seepage performance of the double-layer waterstop structure, but also realize the flexible adjustment of the specific form of the double-layer waterstop structure, thereby meeting the waterstop needs of different hydraulic structures.

[0046] Finally, it should be emphasized that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents. Therefore, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
