Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy dams, in particular to an anti-seepage reinforcement structure of a water conservancy dam. Background Art

[0002] A dam is a water-retaining structure that intercepts the flow of rivers to raise the water level or regulate the flow. Most dams are installed on the riverside or coast and are often used to prevent and control floods.

[0003] A common dam is an earth-rock dam built with soil or stone. Most of the water flow is first intercepted by the bottom of the dam. Only when the water level rises will part of the water flow overflow the bottom of the dam. Because the water pressure on the bottom is greater than that on the top, the bottom of the dam is generally much wider and thicker than the top, and the thickness is generally twice that of the top. Therefore, it has better ability to withstand water pressure. However, due to the impact of water flow over the years, water seepage may occur. The top of the dam is thinner than the bottom. When it is impacted by a large force from the water flow, it is easy for water to flow through the top of the dam and cause seepage. Utility Model Content

[0004] In order to solve the problem that the top of the dam is too thin, it is easy for water to flow through the top of the dam and cause seepage during long-term use.

[0005] To solve the problem, the present application provides a water conservancy dam anti-seepage reinforcement structure.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water conservancy dam anti-seepage reinforcement structure includes a first dam body arranged on a riverbed and a second dam body arranged above the first dam body, wherein a plurality of diversion holes penetrating the interior are opened on a side of the first dam body close to the riverbed, and a diversion hole connected to the diversion holes is opened vertically penetrating the interior, an anti-seepage baffle is installed on a side of the second dam body close to the riverbed, the anti-seepage baffle is detachably connected to the second dam body via a mounting seat, and a plurality of buffer mechanisms are arranged between the anti-seepage baffle and the mounting seat to play a buffering and protective role during flood impact.

[0008] Furthermore, the first dam body and the second dam body include an anti-seepage wall, a concrete protective layer and a crushed stone protective layer arranged in sequence from the outside to the inside, and the diversion hole and the guide hole are both opened inside the anti-seepage wall and the concrete protective layer.

[0009] Furthermore, the second dam body is provided with a plurality of mounting holes in both vertical and horizontal directions, and the mounting holes of the two are intersected and connected with each other. A plurality of fixing rods matching the mounting holes are provided on the side of the mounting seat away from the buffer mechanism, and a plurality of threaded holes are provided on the fixing rods. Bolts are threadedly connected in the threaded holes for fixing the anti-seepage baffle on the outside of the second dam body.

[0010] Furthermore, the mounting holes are provided with matching cover plates.

[0011] Furthermore, the buffer mechanism includes a movable rod, a buffer rod, an elastic component and a limit plate, one end of the movable rod is connected to the anti-seepage baffle, and the other end passes through the buffer rod and is connected to the limit plate, the limit plate is connected to the elastic component away from one end of the buffer rod, the other end of the elastic component is connected to the inner wall of the buffer rod, and the buffer rod is connected to the mounting seat at one end away from the movable rod.

[0012] Furthermore, the inner wall of the buffer rod is symmetrically provided with buffer grooves, and sliding blocks respectively connected to the two ends of the limiting plate are slidably provided inside the buffer grooves.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By opening a number of diversion holes and diversion holes inside the first dam body, the functions of diversion and diversion are played. When the water flow is at a low water level and only impacts the first dam body, a part of the water flow can be diverted to the second dam body, thereby reducing the impact force on the first dam body, preventing high-pressure water from leaking from the first dam body, and extending the service life of the first dam body; by setting an anti-seepage baffle, when the water flow impacts the second dam body, with the cooperation of the anti-seepage baffle and the buffer mechanism, a good buffering and protective effect is played on the second dam body, avoiding seepage caused by long-term use.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 , the utility model provides a technical solution:

[0021] A water conservancy dam anti-seepage reinforcement structure comprises a first dam body 1 arranged on a riverbed and a second dam body 2 arranged above the first dam body 1. The first dam body 1 is provided with a plurality of diversion holes 3 penetrating the interior on a side close to the riverbed, and a diversion hole 15 communicating with the diversion holes 3 is penetrating the interior in a vertical direction. An anti-seepage baffle 4 is installed on a side close to the riverbed of the second dam body 2. The anti-seepage baffle 4 is detachably connected to the second dam body 2 via a mounting seat 5, and a plurality of buffer mechanisms are provided between the anti-seepage baffle 4 and the mounting seat 5 to play a buffering and protective role during flood impact.

[0022] By opening a plurality of diversion holes 3 and guide holes 15 inside the first dam body 1, when the water flow is at a low water level and only impacts the first dam body 1, the water flow will enter the diversion holes 3 and the guide holes 15 respectively, and the pressure of its own impact will cause part of the water flow to be squeezed to the top of the first dam body 1. When the water flow is at a low water level and only impacts the first dam body 1, part of the water flow can be diverted to the second dam body 2, thereby reducing the impact force on the first dam body 1 and preventing high-pressure water from leaking from the first dam body 1; by arranging an anti-seepage baffle 4 on the outside of the second dam body 2, when the water flow impacts, it first contacts the anti-seepage baffle 4, and with the cooperation of the buffer mechanism, it plays a good buffering and protective role on the second dam body 2, avoiding the situation where water flows through and causes seepage due to long-term use.

[0023] The first dam body 1 and the second dam body 2 include an anti-seepage wall 6, a concrete protective layer 7 and a gravel protective layer 8 which are arranged in sequence from the outside to the inside. The diversion holes 3 and the diversion holes 15 are both opened inside the anti-seepage wall 6 and the concrete protective layer 7. The anti-seepage wall 6 is composed of a plurality of concrete wall panels to play an anti-seepage role. The interior is combined with the concrete protective layer 7 and the gravel protective layer 8 to further improve the overall firmness of the dam.

[0024] A plurality of mounting holes 9 are provided in the vertical and horizontal directions in the second dam body 2, and the mounting holes 9 are intersected and connected with each other. A plurality of fixing rods 10 matching the mounting holes 9 are provided on the side of the mounting seat 5 away from the buffer mechanism, and a plurality of threaded holes are provided on the fixing rods 10. Bolts 11 are provided in the threaded connection in the threaded holes for fixing the anti-seepage baffle 4 to the outside of the second dam body 2. During installation, the fixing rods 10 on the mounting seat 5 are inserted into the mounting holes 9 in the horizontal direction, and then the bolts 11 are inserted into the mounting holes 9 in the vertical direction and pass through the threaded holes on the fixing rods 10. The bolts 11 are matched with the threaded holes for fixing and installation, which facilitates installation and disassembly.

[0025] The mounting hole 9 is provided with a cover plate that matches each other. After the anti-seepage baffle plate 4 is fixed by bolts 11, the cover plate can be covered to seal.

[0026] The buffer mechanism includes a movable rod 12, a buffer rod 13, an elastic component 14 and a limit plate 16. One end of the movable rod 12 is connected to the anti-seepage baffle 4, and the other end passes through the buffer rod 13 and is connected to the limit plate 16. The limit plate 16 is connected to the elastic component 14 at one end away from the buffer rod 13, and the other end of the elastic component 14 is connected to the inner wall of the buffer rod 13. The buffer rod 13 is connected to the mounting seat 5 at one end away from the movable rod 12. When the water flow hits the anti-seepage baffle, the movable rod 12 will be squeezed, so that the movable rod 12 drives the limit plate 16 to move the buffer rod 13 and squeezes the elastic component 14 at the same time, so as to offset part of the impact force of the water flow and achieve the effect of buffering protection.

[0027] The inner wall of the buffer rod 13 is symmetrically provided with buffer grooves, and sliders connected to the two ends of the limit plate 16 are slidably arranged inside the buffer groove, so that when the limit plate 16 moves, it is necessary to drive the slider to slide inside the buffer groove, thereby enhancing the buffering effect.

[0028] It should be noted that the elastic component 14 can be a spring or other elastic devices as long as it can achieve the functions described above.
