Formwork for water stop of water conservancy dam

Abstract

The utility model relates to a template for water stop of a water conservancy dam, which comprises a plurality of first water stop plates which are linearly arranged along the width direction of a river, reinforcing structures are mounted on the back surfaces of the first water stop plates, and supporting bottom plates are fixedly connected to the sides, close to the downstream of the river, of the bottom ends of the first water stop plates. Due to the fact that the rubber sealing columns are installed between the first clamping plates, when the river water impacts the first water stop plates and the second water stop plates, the river water is gathered to the connecting positions of the first water stop plates and the second water stop plates under the water diversion action of the water diversion tips and the protruding parts, and the two sides of the second water stop plates are impacted to move towards the first water stop plates to extrude the rubber sealing columns. The peripheral side of the rubber sealing column is tightly attached to the inner side walls of the first clamping plate and the second clamping plate, the larger the impact acting force of river water is, the tighter the rubber sealing column is attached to the inner walls of the first clamping plate and the second clamping plate, the waterproof effect is better, and the problem that the river water is prone to leaking from the splicing position of the water stop formwork is avoided as much as possible.

Description

Technical Field

[0001] This utility model belongs to the field of water conservancy dam construction technology, specifically relating to a template for water-stopping in water conservancy dams. Background Technology

[0002] A dam is an important water conservancy engineering structure, mainly used to intercept water flow, raise river water levels, form upstream regulating reservoirs, and develop and utilize river water resources, integrating flood control, power generation, navigation, and water resource utilization.

[0003] Hydraulic dams are generally formed by pouring high-strength reinforced concrete. Before pouring, a water-stopping structure needs to be installed upstream of the construction site to block the river water in order to facilitate the construction of the dam. The current method is to use water-stopping templates for water-stopping. Since the rivers that can be used to build dams are generally large, multiple water-stopping templates need to be spliced ​​together to form a water-stopping wall. The splicing points of the water-stopping templates are prone to cracks and leakage due to long-term impact from the river water, resulting in poor water-stopping performance of the existing water-stopping templates. Utility Model Content

[0004] The purpose of this utility model is to provide a template for water-stopping in water conservancy dams that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A template for water-stopping in water conservancy dams includes multiple first water-stop plates arranged linearly along the width of a river. A reinforcing structure is installed on the back of each first water-stop plate. A supporting base plate perpendicular to the height direction of the first water-stop plate is fixedly connected to the bottom end of each first water-stop plate near the downstream side of the river. A supporting device is installed between the end of the supporting base plate away from the first water-stop plate and the reinforcing structure. A water-dividing peak is vertically installed on the middle section of each first water-stop plate near the upstream side of the river. A set of first clamping plates is fixedly connected to both ends of the first water-stop plate near the water-dividing peak. A rubber sealing post is installed between two first clamping plates in each set. A second water-stop plate is provided between two adjacent first water-stop plates. A set of second clamping plates for snapping onto the outside of the first clamping plates is fixedly connected to both ends of the second water-stop plate near the rubber sealing post. An arc-shaped protrusion is integrally formed on the middle section of the second water-stop plate away from the second clamping plate.

[0007] As a further optimization of this utility model, the reinforcement structure is a rib plate set on the side of the first waterstop plate near the downstream of the river. The thickness of the middle section of the rib plate is greater than the thickness of the two ends of the rib plate. Both ends of the rib plate are provided with connecting bolts, which pass through the rib plate and are screwed to the first waterstop plate for fixation.

[0008] As a further optimization of this utility model, a connecting seat is fixedly connected to the middle section of the rib plate, and a support seat is fixedly connected to the upper surface of the support base plate away from the first waterstop plate. The support device is a support diagonal rod disposed between the connecting seat and the support seat.

[0009] As a further optimization of this utility model, the end of the supporting base plate away from the supporting seat extends outward to form a pressure plate, and anchors are fixedly connected to the lower surfaces of the pressure plate and the supporting base plate at the ends away from each other.

[0010] As a further optimization of this utility model, a plurality of equidistant right-angled blocks are provided at the connection between the supporting base plate and the first waterstop plate. One right-angled side of the right-angled block is welded to the upper surface of the supporting base plate, and the other right-angled side of the right-angled block is welded and fixed to the side of the first waterstop plate near the downstream of the river.

[0011] As a further optimization of this utility model, the rubber sealing column has a rectangular column structure, the length of the rubber sealing column is not less than the height of the first waterstop plate and the second waterstop plate, and the thickness of the rubber sealing column is greater than the length of the first clamping plate and the second clamping plate.

[0012] The beneficial effects of this utility model are as follows: Since rubber sealing columns are installed between the first plates in each group, when the river water impacts the first and second waterstop plates, the river water is diverted by the water-dividing tip and the protrusion and flows towards the connection between the first and second waterstop plates. It impacts the second waterstop plate and moves towards the first waterstop plate, squeezing the rubber sealing columns. This makes the periphery of the rubber sealing columns fit tightly against the inner walls of the first and second plates. The greater the impact force of the river water, the tighter the rubber sealing columns fit against the inner walls of the first and second plates, resulting in better waterproofing and minimizing the problem of river water easily leaking from the joints of the waterstop template.

[0018] The present application will now be described in further detail with reference to the accompanying drawings.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, a template for water-stopping in water conservancy dams includes multiple first water-stop plates 1 arranged linearly along the width of the river. A reinforcing structure is installed on the back of the first water-stop plates 1. The reinforcing structure is a rib plate 2 set on the side of the first water-stop plate 1 near the downstream of the river. The thickness of the middle section of the rib plate 2 is greater than the thickness of the two ends of the rib plate 2. Connecting bolts 3 are passed through both ends of the rib plate 2. The connecting bolts 3 pass through the rib plate 2 and are screwed to the first water-stop plate 1. The rib plate 2 is set and the two ends of the rib plate 2 are screwed to the two sides of the first water-stop plate 1 by the connecting bolts 3 to reinforce the first water-stop plate 1 and avoid the problem that the first water-stop plate 1 will bend and deform on both sides when it is subjected to the impact of water flow, thus affecting the water-stopping effect of the first water-stop plate 1.

[0021] Multiple first waterstop plates 1 are fixedly connected to a support base plate 4 perpendicular to the height direction of the first waterstop plate 1 on the side of the bottom near the downstream of the river. A support device is installed between the end of the support base plate 4 away from the first waterstop plate 1 and the reinforcement structure. A connecting seat 5 is fixedly connected to the middle section of the rib plate 2. A support seat 6 is fixedly connected to the upper surface of the end of the support base plate 4 away from the first waterstop plate 1. The support device is a support diagonal rod 7 set between the connecting seat 5 and the support seat 6. The support diagonal rod 7 works with the support base plate 4 and the rib plate 2 to provide diagonal support, which can minimize the risk of the first waterstop plate 1 tilting when it is impacted by the water flow.

[0022] Multiple equidistant right-angled blocks 8 are provided at the connection between the supporting base plate 4 and the first waterstop plate 1. One right-angled side of the right-angled block 8 is welded to the upper surface of the supporting base plate 4, and the other right-angled side of the right-angled block 8 is welded and fixed to the side of the first waterstop plate 1 near the downstream of the river. The connection between the supporting base plate 4 and the first waterstop plate 1 is reinforced by the right-angled blocks 8, thereby improving the supporting performance of the supporting base plate 4 on the first waterstop plate 1.

[0023] The end of the supporting base plate 4 away from the supporting seat 6 extends outward to form a pressure plate 9. Anchor nails 10 are fixedly connected to the lower surfaces of the pressure plate 9 and the supporting base plate 4 at the ends away from each other. The pressure plate 9 is set to improve the stability of the installation of the first waterstop plate 1. When the river water impacts the first waterstop plate 1 and causes it to tilt, the pressure plate 9 tilts upward under the action of the first waterstop plate 1. At this time, the river water above can form a reverse force to press down the pressure plate 9 to prevent the first waterstop plate 1 from tilting. The anchor nails 10 are set to anchor the supporting base plate 4 in the riverbed.

[0024] A water-dividing tip 11 is vertically installed on the middle section of the first waterstop plate 1 near the upstream side of the river. A set of first clamping plates 12 are fixedly connected to both ends of the side of the first waterstop plate 1 near the water-dividing tip 11. A rubber sealing post 13 is installed between the two first clamping plates 12 in each set. The water-dividing tip 11 has a triangular structure. When the river water impacts the position of the water-dividing tip 11, the water-dividing tip 11 can separate the river water, allowing the river water to flow through both sides of the water-dividing tip 11, thereby reducing the frontal impact of the river water on the first waterstop plate 1. At the same time, when debris such as tree branches floating in the river water impacts the water-dividing tip 11, it can be buffered by the elastic deformation generated by the water-dividing tip 11, so as to avoid the problem that the first waterstop plate 1 is deformed due to the impact of debris, which would affect the water-stopping effect of the first waterstop plate 1.

[0025] Both ends of the first waterstop plate 1 near the water-dividing peak 11 are fixedly connected to a set of first clamping plates 12. A rubber sealing post 13 is installed between two first clamping plates 12 in each set. The rubber sealing post 13 has a rectangular column structure. A second waterstop plate 14 is set between two adjacent first waterstop plates 1. The second waterstop plate 14 is set on the side of the first waterstop plate 1 near the upstream of the river. Both ends of the second waterstop plate 14 near the rubber sealing post 13 are fixedly connected to a set of second clamping plates 16 for clamping onto the outside of the first clamping plates 12. The middle section of the second waterstop plate 14 away from the second clamping plate 16 has an integrally formed arc-shaped protrusion 15. The length of the rubber sealing post 13 is not less than the height of the first waterstop plate 1 and the second waterstop plate 14. The thickness is greater than the length of the first card plate 12 and the second card plate 16. When the river water impacts the first waterstop plate 1 and the second waterstop plate 14, the river water is diverted by the water-dividing tip 11 and the protrusion 15, and converges at the connection between the first waterstop plate 1 and the second waterstop plate 14. It also acts on the edge of the second waterstop plate 14 located upstream of the river, impacting the second waterstop plate 14 to move towards the first waterstop plate 1 and squeezing the rubber sealing column 13 to deform. This causes the periphery of the rubber sealing column 13 to fit tightly against the inner wall of the first card plate 12 and the second card plate 16. The greater the impact force of the river water, the tighter the rubber sealing column 13 fits against the inner wall of the first card plate 12 and the second card plate 16, thus preventing gaps from easily forming at the splicing position of the waterstop template due to the impact of the river water, which would affect the waterstop effect.

[0026] It should be noted that this type of template for water-stopping dams is used by first fixing the first water-stopping plate 1, supported by the supporting base plate 4 and the supporting diagonal rod 7, to the riverbed at equal intervals using anchor nails 10. Then, the second water-stopping plate 14 is clipped onto the first clamping plates 12 installed at both ends of the first water-stopping plate 1 on the upstream side of the river using the second clamping plate 16. Since a rubber sealing post 13 is installed between the two first clamping plates 12 in each group, when the river water impacts the first water-stopping plate 1 and the second water-stopping plate 14 from upstream, the river water is diverted by the water-dividing tip 11 and the protrusion 15. The water flows towards the junction of the first waterstop plate 1 and the second waterstop plate 14, and acts on the edge of the second waterstop plate 14 located upstream of the river. This impact causes the second waterstop plate 14 to move towards the first waterstop plate 1, squeezing the rubber sealing column 13. This makes the periphery of the rubber sealing column 13 tightly adhere to the inner walls of the first clamping plate 12 and the second clamping plate 16. The greater the impact force of the river water, the tighter the rubber sealing column 13 adheres to the inner walls of the first clamping plate 12 and the second clamping plate 16. This prevents gaps from easily forming at the joint of the waterstop template due to the impact of the river water, which would affect the waterstop effect.

[0027] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
