Technical Field

[0001] The utility model relates to the technical field of anti-seepage walls, in particular to an anti-seepage wall for a water conservancy project. Background Art

[0002] Water conservancy projects, also known as water engineering, are projects constructed to control and allocate natural surface water and groundwater to achieve the goal of eliminating harm and promoting benefits. Water is a valuable resource essential for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can water flows be controlled, floods prevented, and water volume regulated and distributed to meet the water resource needs of people's lives and production. Most building structures in this field require the use of anti-seepage walls as an auxiliary. An anti-seepage wall is an underground continuous wall structure used in water conservancy projects to prevent the penetration of liquids (primarily water).

[0003] However, in the existing technology, when the anti-seepage wall is subjected to water impact for a long time, the microstructure inside the wall material will gradually suffer fatigue damage under the repeated action of various forces generated by the long-term water impact, and the microcracks inside it will continue to expand. As time goes by and water further invades, not only will the microstructure inside the wall material be destroyed and the strength of the wall be reduced, but it will also cause the wall to deform, ultimately affecting its anti-seepage effect. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that not only the microstructure inside the wall material is destroyed and the strength of the wall is reduced, but also the wall is deformed, which ultimately affects its anti-seepage effect.

The lower guide block and the upper guide block are symmetrical about the semicircular block, and the inner wall of the special-shaped steel plate is in contact with the outer wall of the anti-seepage wall body.

[0007] Preferably, the fixing mechanism includes five groups of screws and five groups of nuts, the upper end of the special-shaped steel plate is penetrated by five groups of No. 2 circular holes, and washers are provided at the upper end of the special-shaped steel plate and at the upper ends of the five groups of No. 2 circular holes.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: Figure 1 - Figure 4 As shown, the utility model provides a water conservancy project anti-seepage wall, comprising an anti-seepage wall body 1, two sets of anti-seepage mechanisms 2 are provided on one side of the anti-seepage wall body 1, and the two sets of anti-seepage mechanisms 2 have the same structure, and a fixing mechanism 3 is provided on the upper end of the anti-seepage mechanism 2;

[0023] The anti-collision mechanism 2 includes a special-shaped steel plate 21, a semicircular block 22 is fixedly installed at one end of the special-shaped steel plate 21, a lower guide block 23 is fixedly installed at one end of the special-shaped steel plate 21 and at the lower edge position, and an upper guide block 24 is fixedly installed at one end of the special-shaped steel plate 21 and at the upper edge position. The lower guide block 23 and the upper guide block 24 are symmetrical about the semicircular block 22, and the inner wall of the special-shaped steel plate 21 is in contact with the outer wall of the anti-seepage wall body 1.

[0024] The following describes in detail the specific configuration and function of this embodiment. By assembling a special-shaped steel plate 21 on the outer wall of the anti-seepage wall body 1, the special-shaped steel plate 21 wraps the side of the anti-seepage wall body 1 that contacts water. When water impacts, the impact point of the water will contact the special-shaped steel plate 21, and will not directly impact the anti-seepage wall body 1. This can prevent water from directly impacting the anti-seepage wall body 1, prevent the microstructure inside the anti-seepage wall body 1 from gradually suffering fatigue damage, and will not destroy the microstructure inside the anti-seepage wall body 1, thereby improving the strength of the anti-seepage wall body 1. Moreover, it will not cause deformation of the anti-seepage wall body 1 without affecting its anti-seepage effect.

[0025] With the cooperation of the semicircular block 22, the lower guide block 23 and the upper guide block 24, when water hits the special-shaped steel plate 21, it will flow along the arc of the semicircular block 22, the lower guide block 23 or the upper guide block 24, which can play a guiding effect on the water flow, reduce the impact of water on the special-shaped steel plate 21, and increase the service life of the special-shaped steel plate 21;

[0026] When in use, according to the length of the cut-off wall body 1, by cooperating with multiple anti-collision mechanisms 2, the cut-off wall bodies 1 of different lengths can be protected.

[0027] Example 2: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the fixing mechanism 3 includes five sets of screws 31 and five sets of nuts 33. Five sets of No. 2 circular holes 32 are formed through the upper end of the special-shaped steel plate 21. Washers 34 are provided at the upper end of the special-shaped steel plate 21 and above the five sets of No. 2 circular holes 32. The diameters of the five sets of No. 2 circular holes 32 are the same as the diameters of the five sets of screws 31. The five sets of nuts 33 are respectively threadedly connected to the five sets of screws 31.

[0028] A special-shaped sealing block 11 is welded to one side of the special-shaped steel plate 21, and a special-shaped sealing groove 14 is provided on the other side of the special-shaped steel plate 21. The size of the special-shaped sealing block 11 is the same as that of the special-shaped sealing groove 14. A threaded hole 13 is provided at the upper end of the special-shaped sealing block 11, and a No. 1 round hole 15 is provided through the upper end of the special-shaped steel plate 21. A hexagonal bolt 12 is inserted into the No. 1 round hole 15, and the lower end of the hexagonal bolt 12 is threadedly connected to the threaded hole 13.

[0029] The effect achieved by the entire embodiment is that, when assembling the anti-collision mechanism 2, by inserting the special-shaped sealing block 11 on one side of one special-shaped steel plate 21 into the inside of the special-shaped sealing groove 14 on the side of the other special-shaped steel plate 21, the two sets of special-shaped steel plates 21 can be assembled and a sealing effect can be achieved at the same time. Thereafter, by inserting the hexagonal bolt 12 into the inside of the No. 1 circular hole 15 and screwing the hexagonal bolt 12 so that it rotates toward the internal thread of the threaded hole 13, the special-shaped sealing block 11 can be fixed inside the special-shaped sealing groove 14, thereby fixing the two sets of special-shaped steel plates 21.

[0030] Place the special-shaped steel plate 21 on the upper end of the anti-seepage wall body 1, and respectively put the five groups of No. 2 circular holes 32 on the outer walls of the five groups of screws 31, put the five groups of washers 34 on the five groups of screws 31 one by one, and then screw the five groups of nuts on the outer walls of the five groups of screws 31 one by one until the five groups of nuts are in contact with the five groups of washers 34 respectively, so that the special-shaped steel plate 21 can be fixed to the outer wall of the anti-seepage wall body 1.

[0031] The method of use and working principle of this device: First, according to the length of the anti-seepage wall body 1, multiple anti-collision mechanisms 2 are assembled to the outer wall of the anti-seepage wall body 1, and the special-shaped steel plate 21 is placed on the upper end of the anti-seepage wall body 1, and the five groups of No. 2 round holes 32 are respectively sleeved on the outer walls of the five groups of screws 31, wherein the special-shaped sealing block 11 on one side of one special-shaped steel plate 21 needs to be inserted into the inside of the special-shaped sealing groove 14 on the side of the other special-shaped steel plate 21, and the two groups of special-shaped steel plates 21 can be assembled. Afterwards, by inserting the hexagonal bolt 12 into the inside of the No. 1 round hole 15, and screwing the hexagonal bolt 12 to rotate it toward the internal thread of the threaded hole 13, the special-shaped sealing block 11 can be fixed to the inside of the special-shaped sealing groove 14, which can fix the two groups of special-shaped steel plates 21, and then, the five groups of washers 34 are sleeved. On the five sets of screw rods 31, the five sets of nuts are screwed onto the outer walls of the five sets of screw rods 31 one by one until the five sets of nuts are in contact with the five sets of washers 34 respectively, so that the special-shaped steel plate 21 can be fixed to the outer wall of the anti-seepage wall body 1. Finally, when water impacts, the impact point of water will contact the special-shaped steel plate 21, and will not directly impact the anti-seepage wall body 1, which can prevent water from directly impacting the anti-seepage wall body 1 and prevent the microstructure inside the anti-seepage wall body 1 from gradually suffering fatigue damage. With the cooperation of the semicircular block 22, the lower guide block 23 and the upper guide block 24, when water impacts the special-shaped steel plate 21, it will flow along the curvature of the semicircular block 22, the lower guide block 23 or the upper guide block 24, which can have a guiding effect on the water flow, reduce the impact of water on the special-shaped steel plate 21, and increase the service life of the special-shaped steel plate 21.
