Description

Technical Field

[0001] The utility model relates to the technical field of anti-seepage technology for water conservancy construction, in particular to an anti-seepage and water-stop mechanism for water conservancy construction. Background Technique

[0002] In the construction of water conservancy projects, a copper sheet (also known as a copper water-stop belt or a copper waterproof belt) is a commonly used anti-seepage material, mainly used to prevent water from seeping through structural joints. The copper sheet is widely used in various joints due to its good corrosion resistance, flexibility and weldability, especially in those parts that require long-term reliable anti-seepage. The edges of the copper sheet in contact with the outer layer are sealed and protected by a water-swellable water-stop strip to avoid leakage between the copper sheet and the outer layer contact.

[0003] The information disclosed in this background section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0004] Although the prior art has solved certain problems, it still has the following disadvantages:

[0005] The side of the copper sheet is straight, and the contact with the water-swellable water-stop strip is linear, with a small contact area. The short-distance leakage points between the copper sheet and the contact surface are easily gathered to form leakage, and the stability of anti-seepage and anti-leakage is not good enough. Content of the Utility Model

[0006] The purpose of the utility model is to provide an anti-seepage and water-stop mechanism for water conservancy construction.

[0007] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0014] Further, the side of the impermeable copper sheet extends 100 mm to 200 mm from the splicing joint.

[0015] Further, the impermeable copper sheet is fixedly connected to the outer side of the concrete protective layer through a cement-based binder.

[0016] Further, the water-swelling waterstop strip is fixedly connected to the outer side of the concrete protective layer through a cement-based binder.

The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment 1:

[0033] As Figures 1 to 5 shown, this embodiment proposes a seepage prevention and water stop mechanism for water conservancy construction, including a retaining wall 1, an anti-seepage copper sheet 2, a water-swelling water stop strip 3, a positioning mechanism 4, an SBS modified asphalt layer 5, a splicing joint 6, a waterproof board 7, a concrete protective layer 8, an anti-seepage extension groove 9, a fitting cutting edge 10, and a connecting rod 11 disposed inside the splicing joint 6 for connecting two anti-seepage copper sheets 2.

[0034] Among them, the splicing joints 6 formed between the retaining walls 1 due to prefabrication, construction splicing, pouring butt-joints, etc., including the main construction joints such as construction joints and expansion joints, are provided with waterproof plates 7 on both sides of the retaining walls 1 to perform anti-seepage and water leakage prevention treatment on the retaining walls 1. Concrete protective layers 8 are arranged on the outer sides of the waterproof plates 7 to protect the waterproof plates 7, reduce the possibilities of oxidation, abrasion, leakage, etc., and ensure the integrity of the waterproof plates 7. Anti-seepage copper sheets 2 are arranged at the positions of the splicing joints 6 on the outer sides of the concrete protective layers 8. The mutually approaching sides of the anti-seepage copper sheets 2 are recessed into the interiors of the splicing joints 6. Since the splicing joints 6 function to accommodate the thermal expansion and contraction of the concrete structure to adapt to temperature changes and cause deformation, the middles of the anti-seepage copper sheets 2 are recessed inward, which can accommodate the expansion and contraction deformation of the concrete structure. Moreover, due to the good anti-oxidation, electrical conductivity, thermal conductivity, airtightness and ductility of copper, it is convenient to maintain the sealing of the interior of the splicing joints 6 after the anti-seepage copper sheets 2 are deformed.

[0035] Both sides of the anti-seepage copper sheet 2 extend 100 mm to 200 mm beyond the edges of the splicing joint 6 to ensure the anti-seepage sealing treatment of the anti-seepage copper sheet 2 for the splicing joint 6 according to specific construction requirements. A number of uniformly distributed anti-seepage extension grooves 9 are opened on both sides of the anti-seepage copper sheet 2. Since the two sides of the anti-seepage copper sheet 2 are normally straight lines, when leakage points appear in the interior of the splicing joint 6 from the gaps where the anti-seepage copper sheet 2 contacts the concrete protective layer 8, the leakage points at short distance intervals are likely to approach and converge with each other, damaging the contact protection between the anti-seepage copper sheet 2 and the concrete protective layer 8 and concentrating to form leakage points, while the water-swelling waterstop strips 3 contacting the straight edges on both sides of the anti-seepage copper sheet 2 have a small contact area with it.

[0036] In this application, the anti-seepage extension grooves 9 are arranged in a trapezoid-like shape, making the two sides of the anti-seepage copper sheet 2 serrated, increasing the line length of its edges. The water-swelling waterstop strips 3 on both sides of the anti-seepage copper sheet 2 are provided with fitting cutting edges 10 having the same shape as the anti-seepage extension grooves 9 on the sides facing the anti-seepage copper sheet 2. The fitting cutting edges 10 are engaged into the interiors of the anti-seepage extension grooves 9 of the anti-seepage copper sheet 2, increasing the contact area between the water-swelling waterstop strips 3 and the edges of the anti-seepage copper sheet 2, increasing the anti-seepage airtightness and reducing the risk of the concentration of seepage points.

[0037] On the outer side of the concrete protective layer 8, it is all cast through the SBS modified asphalt layer 5. The inner side of the impermeable copper sheet 2 and the inner side of the water-swelling waterstop strip 3 are both adhesively fixed on the outer side of the concrete protective layer 8 through a cement-based binder, and the outside is covered and fixed by casting through the SBS modified asphalt layer 5. The SBS modified asphalt layer 5 has a certain deformation ability and is not easily cracked, providing impermeability protection for the inside of the splicing joint 6. In order to enhance the contact stability and connection strength between the water-swelling waterstop strip 3 and the concrete protective layer 8, card slots 401 are opened on the outer layer of the concrete protective layer 8, and card bumps 402 are fixedly connected to the side of the water-swelling waterstop strip 3 attached to the concrete protective layer 8, increasing the firmness of the connection between the water-swelling waterstop strip 3 and the concrete protective layer 8.

[0038] Embodiment 2:

[0039] The solution in Embodiment 1 will be further introduced below in combination with the specific working method. See the following description for details:

[0040] In order to slow down the stretching speed of the impermeable copper sheet 2 due to the elongation of the splicing joint 6, on the side where the impermeable copper sheets 2 are close to each other, a connecting rod 11 made of 60Si2MnA medium-carbon alloy spring steel is provided for connection. When the splicing joint 6 elongates, the impermeable copper sheet 2 that is recessed into the splicing joint 6 is pulled open and moves towards the outside of the splicing joint 6. There is a tendency for the middle parts of the impermeable copper sheets 2 to move away from each other. Through the elasticity of the connecting rod 11, the speed at which the impermeable copper sheet 2 is pulled and extended is slowed down. And after being stretched, when the inside of the splicing joint 6 narrows, the connecting rod 11 pulls the middle parts of the impermeable copper sheets 2 back into the depression inside the splicing joint 6.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
