[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water stop device for the joint of a water conservancy channel dam body. Background Technique
[0002] In the dam body of a water conservancy channel, in order to facilitate the heat dissipation of concrete during construction and reduce the shrinkage stress, the dam body usually needs to be jointed. The existence of these joints can effectively reduce the stress generated by the dam body due to factors such as temperature changes and foundation deformation, and improve the stability and safety of the dam body. In order to prevent the water flow from scouring and damaging the dam body joint, a water stop device is provided at the outer end of the joint.
[0003] However, the existing water stop devices for the joints of water conservancy channel dam bodies generally use a single-layer waterproof board for protection and water stop. Since the waterproof board is in direct contact with the water flow and is continuously scoured by the water flow for a long time, it corrodes and wears relatively quickly. When it is damaged, the water flow will directly scour the dam body joint, causing its damage, and its protection and water stop ability is weak and its practicability is poor.
[0004] In order to solve this technical problem, the utility model provides a water stop device for the joint of a water conservancy channel dam body. Content of the Utility Model
[0005] The main purpose of the utility model is to provide a water stop device for the joint of a water conservancy channel dam body, which can effectively solve the problems mentioned in the background technique.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A water stop device for the joint of a water conservancy channel dam body, including a dam body plate, an inner plate is arranged on the surface of the dam body plate, a concave panel is arranged inside the inner plate, an outer protection plate is arranged at the outer end of the inner plate, a convex panel is arranged inside the outer protection plate, an expansion strip is arranged between the concave panel and the convex panel, bending plates are arranged on both sides of the outer protection plate, a first waterproof strip is arranged at the side end of the bending plate, a second waterproof strip is arranged on both sides of the inner plate, expansion bolts are arranged inside the outer protection plate, and a pressing strip is arranged between the outer protection plate and the inner plate.

[0010] Preferably, the convex panel is located at the outer end of the concave panel, the expansion strip can absorb water and expand, the concave panel and the bending plate can both be bent and deformed, and the first waterproof strip is located at the side end of the second waterproof strip.
[0011] Preferably, installation holes are formed in the outer protection plate, expansion bolts are located in the installation holes, a sealing gasket is arranged between the bolt head of the expansion bolt and the outer protection plate, the expansion bolts are located at the side end of the inner side plate, and the expansion bolts are connected in the dam body plate.
[0012] Preferably, clamping strips are connected to the upper end of the inner side plate and the lower end of the outer protection plate, clamping grooves are formed in the side end of the pressing strip, and the pressing strip is clamped in the clamping strips.
[0013] Preferably, a baffle is connected to the side end of the inner side plate, the expansion strip is located in the baffle, a push cover is arranged at the upper end of the expansion strip, the push cover can be connected to the inner side of the outer protection plate, clamping plates are connected to both sides of the push cover, the clamping plates are located at the outer end of the baffle and are slidably connected thereto, and water permeable holes are formed in the pressing strip, the baffle and the clamping plates.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] In the utility model, by providing the inner side plate and the outer protection plate, the inner side plate covers and protects the connection gap of the dam body plate, and the outer protection plate protects the inner side plate. The two-layer protection structure can effectively prevent the water flow from scouring the joint of the dam body plate. Specifically, the inner side plate and the outer protection plate are installed at the connection gap of the dam body, and then the outer protection plate is installed and fixed by using expansion bolts. At this time, as the expansion bolts drill into the dam body plate, the bending plate will contact the dam body plate and be bent under pressure, so that the first waterproof strip can be tightly attached to the surface of the dam body plate, thereby forming the first layer of waterproofing. At the same time, the outer protection plate will squeeze the inner side plate through the pressing strip, so that the second waterproof strip can be attached to the surface of the dam body. This device has two layers of waterproofing, with good waterproof effect, convenient installation, can effectively protect the connection seam of the dam body plate, has good protection and water-stop effect, and strong practicability.
[0016] In the utility model, by providing the expansion strip, since the first waterproof strip is in direct contact with the water flow and will be scoured by the water flow, it is corroded and worn relatively fast. When the first waterproof strip is damaged, the water flow will enter the outer protection plate. Since water permeable holes are formed in the pressing strip, the baffle and the clamping plates, the water flow will contact the expansion strip through the water permeable holes, so that the expansion strip can expand. Therefore, it can squeeze the inner side plate, so that the second waterproof strip is pressed, so that it fits more tightly with the dam body plate. And after the water flow impacts the outer protection plate, its flow velocity will be reduced, so that the scouring force on the inner side plate is weaker, thus effectively protecting the inner side plate and effectively improving the protection and water-stop effect of the device.

The outer end of the concave panel 3 is connected with a sealing rod 13. The sealing rod 13 is made of corrosion-resistant rubber and has elasticity. The sealing rod 13 is located at the connection gap of two dam body plates 1, and the sealing rod 13 is used to seal the joint of the dam body plate 1.
[0024] An outer protection plate 4 is provided at the outer end of the inner side plate 2. The outer protection plate 4 completely wraps the inner side plate 2, so that the outer protection plate 4 can protect the inner side plate 2. The outer protection plate 4 is in direct contact with the water flow and is washed by the water flow. A pressure strip 11 is provided between the outer protection plate 4 and the inner side plate 2. The pressure strip 11 is used to connect the outer protection plate 4 and the inner side plate 2 together. A convex panel 5 is provided inside the outer protection plate 4. The convex panel 5 is located at the outer end of the concave panel 3. The convex panel 5 can effectively relieve the impact force generated by the water flow impact, thereby ensuring that the device will not fall off due to the water flow impact. An expansion strip 6 is provided between the concave panel 3 and the convex panel 5. The expansion strip 6 can absorb water and expand.
[0025] Bending plates 7 are provided on both sides of the outer protection plate 4. The concave panel 3 and the bending plates 7 can be bent and deformed. The bending plates 7 are in an arc-shaped streamline, which can effectively relieve the impact generated by the water flow scouring. A first waterproof strip 8 is provided at the side end of the bending plate 7. Second waterproof strips 9 are provided on both sides of the inner side plate 2. The first waterproof strip 8 is located at the side end of the second waterproof strip 9. In this way, the device has two layers of waterproofing, and its waterproof effect is good, which can effectively prevent the water flow from scouring the joint of the dam body plate 1.
[0026] Expansion bolts 10 are provided inside the outer protection plate 4. Installation holes are provided inside the outer protection plate 4. The expansion bolts 10 are located in the installation holes. A sealing gasket is provided between the bolt head of the expansion bolt 10 and the outer protection plate 4.

The expansion bolts 10 are connected inside the dam body plate 1. In this way, the device can be installed and fixed on the dam body plate 1. When the expansion bolts 10 gradually drill into the dam body plate 1, at this time, they can squeeze the outer protection plate 4, so that the bending plates 7 can act on the dam body plate 1, and the bending plates 7 can be pressed, so as to provide pressure on the first waterproof strip 8, so that it can be closely attached to the surface of the dam body plate 1, and its waterproof effect is good.
[0027] A clamping strip 14 is connected to both the inner side plate 2 and the lower end of the outer protection plate 4. A clamping groove is formed at the side end of the pressing strip 11, and the pressing strip 11 is clamped in the clamping strip 14, so that the clamping strip 14 can be clamped and fixed. A baffle 201 is connected to the side end of the inner side plate 2. The expansion strip 6 is located inside the baffle 201. A push cover 202 is arranged at the upper end of the expansion strip 6.

Under the action of the clamping plates 203 and the baffle 201, the expansion strip 6 will squeeze the concave panel 3, so that a thrust can be generated on the inner side plate 2, and thus the second waterproof strip 9 can be pressed, so that it fits more closely with the dam body plate 1. At the same time, the sealing rod 13 can also be pushed to make its joint with the dam body plate 1 more tight, so as to improve the waterproof effect of the device.
