Description

Technical Field

[0001] The utility model relates to the technical field of dam structures, and in particular to a dam structure. Background Art

[0002] A dam is the general term for a dike and a dam, and also generally refers to buildings and structures for waterproofing and water retaining. Modern dams mainly fall into two categories: concrete dams and earth-rock dams. In recent years, large dams have been built with reinforced cement. Concrete dams are mostly built with concrete and are usually constructed in deep and narrow valleys. The main feature of a concrete dam is to use its own weight to support the water pressure. An earth-rock dam is a wide dam built with soil or stones and is mostly built across a large river. Since the water pressure at the bottom is much greater than that at the top, the bottom is wider than the top. Dams are widely used in various environments. For example, dams are also common in saline-alkali land.

[0003] After retrieval, a Chinese utility model patent with the publication number (CN215367114U) specifically discloses an anti-seepage and anti-scour water conservancy dam structure, which includes a dam body. L-shaped anti-scour layers are provided on both sides of the dam body. Among them, the L-shaped anti-scour layer includes an inclined part and a horizontal part, and the lower end of the inclined part is fixedly connected to one end of the horizontal part away from the dam body. Grooves corresponding to the positions of the horizontal parts are provided at the bottoms on both sides of the dam body, and one end of the horizontal part away from the inclined part is inserted into the grooves. A cavity is provided between the dam body and the inclined part. Among them, the cavity is filled with a protection structure, and the dam body and the protection structure are fixed by steel pins. The protection structure includes a corrosion-resistant layer, a waterproof cotton layer, a waterproof board layer, and a resin glue layer that are fixedly connected in sequence. Among them, the inner wall of the corrosion-resistant layer is fixed to the outer wall of the dam body, and the outer wall of the resin glue layer is fixed to the inner wall of the inclined part.

[0004] In the above patent, only through the combined use of the L-shaped anti-scour layer, the corrosion-resistant layer, the waterproof cotton layer, the waterproof board layer, and the resin glue layer, anti-seepage and anti-scour are achieved. However, the above dam is only placed on the ground relying on its own gravity and does not have a reinforcement structure, making it difficult to further fix the position of the dam body and difficult to ensure the stable use of the dam.

[0023] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0024] It should be noted that the dam structure of the embodiment of the present utility model is mainly used for saline-alkali land of a salt lake.

[0025] As Figures 1 to 3 shown, the embodiment of the present utility model provides a dam structure. The dam structure is installed on a foundation to be installed. The dam structure includes a dam main body 10, two bases 7 and two reinforcement components 6. Among them, the two bases 7 are respectively connected to opposite sides of the dam main body 10; the two reinforcement components 6 are correspondingly arranged on the two bases 7. The reinforcement component 6 includes a main reinforcement member 61 and an auxiliary reinforcement member. The main reinforcement member 61 is a cylindrical structure with an installation cavity. The main reinforcement member 61 passes through the base 7 and is inserted into the foundation to be installed. A moving channel communicating with the installation cavity is provided on the main reinforcement member 61. At least part of the auxiliary reinforcement member is located in the installation cavity. The auxiliary reinforcement member has a reinforcement end 610 that can be movably arranged in the moving channel, so that the reinforcement end 610 has a storage position for retracting into the moving channel and a reinforcement position for protruding out of the moving channel and protruding from the main reinforcement member 61.

[0026] In the above technical solution, on the one hand, by inserting the main reinforcement member 61 into the foundation to be installed (soil), the foundation to be installed can provide a pulling force to the dam main body 10 through the main reinforcement member 61; on the other hand, by making the reinforcement end 610 protrude out of the moving channel and inserting it into the foundation to be installed, that is, the reinforcement end 610 is in the reinforcement position, the foundation to be installed can provide a pulling force to the dam main body 10 through the auxiliary reinforcement member. In this way, compared with the prior art in which the installation of the dam structure is only achieved by relying on the self-gravity of the dam structure, in this embodiment, the foundation to be installed provides a double pulling force to the dam main body 10 through the main reinforcement member 61 and the auxiliary reinforcement member, which can effectively increase the stability of the dam structure, so that the dam structure can be stably installed on the foundation to be installed.

[0027] As Figure 1As shown, in the embodiment of the utility model, the moving channel is arranged at an angle to the axis of the cylindrical structure.

[0028] Through the above arrangement, the main reinforcement member 61 and the auxiliary reinforcement member can provide tension in two different directions to the dam body 10 to further reinforce the position of the dam body 10 so that the dam body 10 can be stably placed in the working area for use.

[0029] Preferably, in the embodiment of the utility model, the moving channel and the axis of the cylindrical structure are arranged perpendicularly, and the axis of the cylindrical structure is arranged along Figure 1 The moving channel extends in the vertical direction of Figure 1 The reinforcement assembly 6 extends in the horizontal direction, so that the reinforcement assembly 6 can apply a horizontal and a vertical pulling force to the dam body 10.

[0030] like Figure 1 and Figure 2 As shown, in an embodiment of the utility model, the auxiliary reinforcement member includes: a driving mechanism, having a driving end 63 movably arranged along the axis of the cylindrical structure; a deformation mechanism, the deformation mechanism having a fixed portion 68, a movable portion 612 and two output portions 611, the movable portion 612 is connected to the fixed portion 68 through the two output portions 611, and the two output portions 611 are respectively provided with reinforcement ends 610 on the sides opposite to each other, the fixed portion 68 is supported at the bottom of the installation cavity, the movable portion 612 is connected to the driving end 63, the movable portion 612 is movably arranged along the axis of the cylindrical structure relative to the fixed portion 68, and the movable portion 612 can drive the two output portions 611 to move closer to or away from each other.

[0031] Through the above arrangement, after the main reinforcement component 61 is inserted into the foundation to be installed, the driving end 63 can drive the movable part 612 to move in the direction close to the fixed part 68, thereby driving the two output parts 611 to move away from each other. In this way, the two output parts 611 will drive the two reinforcement ends 610 to move away from each other, so that each reinforcement end 610 can extend out of the corresponding moving channel and protrude out of the main reinforcement component 61 and then be inserted into the foundation to be installed, so as to achieve reinforcement and fixation of the dam body 10; and the driving end 63 drives the movable part 612 to move in the direction away from the fixed part 68, and the two output parts 611 can drive the two reinforcement ends 610 to approach each other, so that the reinforcement ends 610 retract into the moving channel. In this way, the main reinforcement component 61 can be pulled out from the foundation to be installed, so as to adjust the position of the dam structure.

[0032] like Figure 2As shown, in the embodiment of the present utility model, the deformation mechanism includes a movable disk, a first movable plate 613, a first output rod, a second movable plate 614, a fixed disk, a third movable plate 615, a second output rod, and a fourth movable plate 616 that are pivotally connected in sequence from head to tail to form an octagonal link mechanism. Among them, the movable disk forms a movable part 612, the fixed disk forms a fixed part 68, and the first output rod and the second output rod form two output parts 611.

[0033] With the above settings, the driving end 63 drives the movable disk to move towards the fixed disk, so as to drive the first output rod to move away from the axis of the cylindrical structure through the first movable plate 613, and drive the second output rod to move away from the axis of the cylindrical structure through the fourth movable plate 616. The first output rod and the second output rod can respectively drive the second movable plate 614 and the third movable plate 615 to open. In this way, the two reinforcement ends 610 can move in opposite directions, so that the reinforcement ends 610 extend out of the moving channel and are inserted into the foundation to be installed.

[0034] Specifically, in the embodiment of the present utility model, the deformation mechanism further includes a pivot shaft 67. Any two adjacent components among the movable disk, the first movable plate 613, the first output rod, the second movable plate 614, the fixed disk, the third movable plate 615, the second output rod, and the fourth movable plate 616 are pivotally connected through the pivot shaft 67. For example, as Figure 3 shown, the end of the fixed disk is provided with a fixed groove and two through holes communicating with the fixed groove. The two through holes are respectively located on both sides of the fixed groove. The two ends of the pivot shaft 67 are respectively in rotational cooperation with the two through holes. One end of the third movable plate 615 is located in the fixed groove and is in rotational cooperation with the pivot shaft 67 to realize the pivotal connection between the third movable plate 615 and the fixed disk.

[0035] As Figure 2 shown, in the embodiment of the present utility model, a pressing plate 69 is provided on each output part 611, and a plurality of insertion rods are provided on the side of the pressing plate 69 facing away from the output part 611. Each insertion rod forms a reinforcement end 610.

[0036] With the above settings, the output part 611 drives a plurality of insertion rods through the pressing plate 69, so that the plurality of insertion rods can move in the plurality of moving channels and extend out of the moving channels and be inserted into the foundation to be installed, thereby the dam structure can be reinforced.

[0037] Specifically, in the embodiment of the present utility model, a plurality of moving channels are provided on both sides of the main reinforcement member 61, and the plurality of moving channels on each side of the main reinforcement member 61 are correspondingly arranged with the plurality of insertion rods on each pressing plate 69.

[0038] As Figure 1As shown in the figure, in the embodiment of the present utility model, the driving mechanism includes: a turning handle 65 rotatably connected to the main reinforcement member 61; a pressing rod, the turning handle 65 is located on the outer periphery of the pressing rod, the pressing rod is movably arranged relative to the main reinforcement member 61, one end of the pressing rod abuts against the movable part 612, the other end of the pressing rod extends out of the installation cavity and is in threaded cooperation with the turning handle 65, and the pressing rod forms a driving end 63.

[0039] In the above technical solution, by rotating the turning handle 65, the pressing rod can be driven to move relative to the main reinforcement member 61 along the axis of the pressing rod itself, so that the movable disk can be moved relative to the fixed disk by using the pressing rod, so that the two output parts 611 can approach or move away from each other.

[0040] As Figure 1 As shown in the figure, in the embodiment of the present utility model, a through hole communicating with the installation cavity is provided on the main reinforcement member 61 for the pressing rod to pass through. A limiting member 64 is provided at one end of the pressing rod away from the movable part 612. The cross-sectional area of the through hole is smaller than the cross-sectional area of the turning handle 65, and the cross-sectional area of the turning handle 65 is smaller than the cross-sectional area of the limiting member 64. In this way, the extreme displacement of the pressing rod can be limited to prevent the pressing rod from moving completely into the installation cavity, thereby avoiding affecting the operation of personnel.

[0041] Specifically, in the embodiment of the present utility model, the through hole is in rotational cooperation with the pressing rod.

[0042] As Figure 1 As shown in the figure, in the embodiment of the present utility model, the first end of the main reinforcement member 61 is connected to the base 7, and an insertion member 62 is provided at the second end of the main reinforcement member 61. The cross-sectional area of the insertion member 62 gradually decreases in the direction from the first end to the second end. In this way, it is convenient to insert the main reinforcement member 61 into the foundation to be installed.

[0043] As Figure 1 As shown in the figure, in the embodiment of the present utility model, the dam body 10 includes: a base body; a protection plate 8 provided on at least one side of the base body; a plurality of conical wave-breaking plates 9, and a plurality of conical wave-breaking plates 9 are provided at intervals on the side of the protection plate 8 facing away from the base body, and each conical wave-breaking plate 9 is inclined relative to the bottom wall of the protection plate 8 facing the base body.

[0044] Through the above settings, the protection plate 8 and the conical wave-breaking plates 9 can be used in combination. On the one hand, the protection plate 8 can protect the base body to prevent the base body from being washed away and prevent the base body from being penetrated by water waves; on the other hand, the plurality of conical wave-breaking plates 9 can conveniently divert and unload the water waves, thereby effectively alleviating the impact force generated by the water waves on the base body, avoiding strong rigid impact of the water waves on the base body, and further reducing the use strength of the dam structure and prolonging the service life of the dam structure.

[0045] Specifically, in the embodiment of the present utility model, the conical wave-breaking plate 9 includes a main body section connected to the protection plate 8 and a conical section connected to the main body section. In the direction from the conical section to the main body section, the cross-sectional area of the conical section gradually decreases.

[0046] As Figure 1 shown, in the embodiment of the present utility model, water leakage holes are provided on each conical wave-breaking plate 9. In this way, the water wave can be shunted and unloaded to reduce the impact of the water wave on the conical wave-breaking plate 9.

[0047] As Figure 1 and Figure 2 shown, in the embodiment of the present utility model, the auxiliary reinforcement member further includes a support member 66 connected to the bottom wall of the installation cavity, and the fixing portion 68 is fixed to the support member 66. In this way, the support member 66 can support the deformation mechanism to provide a support force for the deformation mechanism when the deformation mechanism deforms.

[0048] Specifically, in the embodiment of the present utility model, the support member 66 includes two L-shaped support rods, one end of each L-shaped support rod is fixed to the main reinforcement member 61, and the other end of each L-shaped support rod is connected to a fixing disk.

[0049] As Figure 1 shown, in the embodiment of the present utility model, the base body includes a dam body 1, a corrosion-resistant layer 2 is connected to the outer surface of the dam body 1, a waterproof cotton layer 3 is connected to the outer surface of the corrosion-resistant layer 2, a resin glue layer 4 is sleeved on the waterproof cotton layer 3, the inner wall of the resin glue layer 4 is connected to the outer wall of the waterproof cotton layer 3, and a protection layer 5 is connected to the outer surface of the resin glue layer 4. Figure 1 In Figure 1 the protection layer 5, bases 7 are connected to both sides near the bottom, fixing through holes are provided in both bases 7, and reinforcement assemblies 6 are provided in both fixing through holes.

[0050] Specifically, in the embodiment of the present utility model, the outer walls of the two main reinforcement members 61 are connected to the inner walls of the fixing through holes.

[0051] It should be noted that with reference to Figures 1 to 3, during use, first, the staff uses a hoisting machine to steadily place the dam body 10 in the saline-alkali land use area. At the same time, due to the gravity of the dam body 10, the two main reinforcement members 61 are inserted into the soil interior through the two inserts 62, so that the two bases 7 are in contact with the ground. After the dam structure is hoisted and placed, the staff rotates the two turning handles 65 in the forward direction in sequence. When the two turning handles 65 rotate forward, they engage with the threaded structures of the two abutting rods, so as to drive the two abutting rods to start moving towards the bottoms of the two main reinforcement members 61. When the two limit members 64 come into contact with the two turning handles 65, the staff stops rotating the two turning handles 65 and puts two protective covers on the outer sides of the two turning handles 61. Among them, when each abutting rod moves downward, it can drive the corresponding movable plate downward. When the movable plate moves downward, it can drive the first movable plate 613 and the fourth movable plate 616 to gradually rotate towards the horizontal state. When the first movable plate 613 and the fourth movable plate 616 rotate towards the horizontal state, they can drive the first output rod and the second output rod to start moving towards both sides respectively. When the first output rod and the second output rod move towards both sides, they can make the second movable plate 614 and the third movable plate 615 also start rotating towards the horizontal state, so as to limit the positions of the first output rod and the second output rod, so that the first output rod and the second output rod can steadily drive the two abutting plates 69 to move towards both sides, so that the two abutting plates 69 can quickly push out multiple inserting rods from the installation cavities of the main reinforcement members 61 and insert them into the soil interior respectively, so as to further fix the positions of the two bases 7, so that the dam structure can be firmly placed in the use area for use. After the dam body 10 is fixed, the staff uses a hoisting machine to clamp the two protective plates 8 into the two placement grooves. During the use of the dam structure, when encountering water waves, the water waves slap on the outer sides of the multiple conical wave-breaking plates 9, so that the conical sides of the multiple conical wave-breaking plates 9 can quickly divert and unload the water waves, thereby reducing the impact force generated by the water waves on the dam structure to protect the dam structure. And because the dam structure is provided with a corrosion-resistant layer 2, a waterproof cotton layer 3, a resin glue layer 4 and a protective layer 5 on the outer side of the dam body 1, it can further play the role of preventing penetration and impact on the dam body 1.

[0052] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: on the one hand, by inserting the main reinforcement member into the foundation to be installed (soil), the foundation to be installed can provide tensile force to the dam body through the main reinforcement member; on the other hand, by making the reinforcement end extend out of the moving channel and insert into the foundation to be installed, that is, the reinforcement end is in the reinforcement position, the foundation to be installed can provide tensile force to the dam body through the auxiliary reinforcement member. In this way, compared with the prior art where the installation of the dam structure is achieved only by relying on the self-gravity of the dam structure, in this embodiment, the foundation to be installed provides double tensile forces to the dam body through the main reinforcement member and the auxiliary reinforcement member, which can effectively increase the stability of the dam structure so that the dam structure can be stably installed on the foundation to be installed.

[0053] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
