Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a supporting structure for river slopes. Background Art

[0002] The river slope refers to the slope from the water surface to the bank on both sides of the river. The river slope plays an important role in the river ecosystem, not only affecting the river's morphology and water flow dynamics, but also related to the stability of the river bank, soil and water conservation, and biodiversity.

[0003] Usually, one side of the river slope contacts the river and the other side contacts the river bank soil. At the same time, it is squeezed by the river water pressure and soil gravity. Generally, reinforced concrete is used to form a slope structure, and the bottom is fixed by anchor rods. This kind of river slope has high stability and can withstand large loads. However, with the change of climate in recent years, some rivers in my country are prone to more severe floods. For straight rivers, the impact of water flow on the slope is relatively limited, but in some rivers with sharp turns, the water flow is easy to have a high short-term impact on the slope. The ability of reinforced concrete slopes to withstand constant loads is relatively excellent, but for the instantaneous large loads caused by the increase in short-term river flow due to the frequent extreme weather nowadays, the traditional reinforced concrete slopes can provide limited support capacity. In addition, the steel structure of the slope is lined inside the concrete. If it is damaged and deformed after long-term use, it is difficult to detect and maintain. Summary of the invention

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] Combined with Figure 1 and attached Figure 2 A supporting structure for a river slope includes a concrete slope 1, a river channel 2, a buffer elbow 7 and a one-way damper 8. The concrete slope 1 is arranged outside the bend of the river channel 2. A structural cavity 3 is arranged in the middle of the concrete slope 1. The buffer elbow 7 and the one-way damper 8 are respectively arranged on the front and rear sides of the structural cavity 3.

[0027] Combined with Figure 3 and attached Figure 6 A central bracket 4 is provided on both sides of the one-way damper 8 in the structural cavity 3, and a supporting steel frame 5 is symmetrically provided on the front and rear sides of the central bracket 4. Shrapnel 21 is symmetrically provided on the upper and lower sides between the central bracket 4 and the supporting steel frame 5.

[0028] As attached Figure 2 As shown, the arrow indicates the direction of water flow in the river channel 2, and the present invention is arranged on the outer side of the bend of the river channel 2 facing the direction of the water flow.

[0029] When the above structure is implemented, the installation effect of each component of the present invention is shown in the attached Figure 2 and attached Figure 3 The central support 4 and the supporting steel frame 5 are initially fixed by anchor rods 6, and then concrete is poured in the trapezoidal area formed by the supporting steel frames 5 on both sides to finally form a concrete slope 1. During the pouring process, in addition to maintaining the external slope of the concrete slope 1, space must be reserved for the structural cavity 3. After the construction of the present invention is completed, the space of the structural cavity 3 is required for the convenience of the staff to inspect and maintain the various components of the present invention.

[0030] Combined with Figure 5 and attached Figure 6 The supporting steel frame 5 is provided with connecting components 13 on both the upper and lower sides. The spring piece 21 is bow-shaped, one end of which is fixedly connected to the middle of the central bracket 4, and the other end is fixedly connected to the connecting component 13.

[0031] Combined with Figure 4 and attached Figure 8 A first limiting wheel bracket 22 is provided in the middle of the central bracket 4, and a plurality of first limiting wheels 10 are connected to the first limiting wheel bracket 22. A first fixing pin block 23 is provided on the outer side of the first limiting wheel bracket 22. The connecting component 13 is provided with a second limiting wheel bracket 24, and a plurality of second limiting wheels 17 are connected to the second limiting wheel bracket 24. A second fixing pin block 25 is provided on the outer side of the second limiting wheel bracket 24.

[0032] Combined with Figure 4 , Attachment Figure 5 and attached Figure 8 One end of the spring piece 21 is fitted with the first limiting wheel 10, and the other end is fitted with the second limiting wheel 17. One end of the spring piece 21 is fitted with the first limiting wheel 10, and the other end is fitted with the second limiting wheel 17. A fixed wheel 20 is provided at the connection between the spring piece 21 and the first limiting wheel 10 and the second limiting wheel 17. The fixed wheel 20 and the first limiting wheel 10 are respectively located at the upper and lower sides of the top end of the spring piece 21, and the fixed wheel 20 and the second limiting wheel 17 are respectively located at the spring piece 2 At the upper and lower sides of the bottom end, the fixing wheel 20, the first limiting wheel 10 and the second limiting wheel 17 jointly limit the end of the spring piece 21. The fixing wheel 20 is provided with a third fixing pin block 29 at both ends. The third fixing pin block 29 is aligned with the adjacent first fixing pin block 23 or the second fixing pin block 25. The integral pin block formed by the third fixing pin block 29 and the first fixing pin block 23 and the integral pin block formed by the third fixing pin block 29 and the second fixing pin block 25 are wrapped and nested with a fixing hoop 26.

[0033] Combined with Figure 4 and attached Figure 5 A limiting groove 9 is provided at the connection between the central bracket 4 and the spring sheet 21 , and a top block 18 is provided at the connection between the connecting component 13 and the spring sheet 21 .

[0034] The present invention uses the above structure to elastically connect the side of the concrete slope 1 that contacts the river and the side that is close to the land through multiple spring pieces 21. Since the present invention focuses on providing the outer slope of the river channel 2 with the ability to resist instantaneous impact, the material selection and thickness of the spring pieces 21 should have sufficient redundancy.

[0035] In the above structure, the first limiting wheel 10 , the second limiting wheel 17 and the fixed wheel 20 limit the spring piece 21 together, and the contact between the two ends of the spring piece 21 by the limiting groove 9 and the top block 18 is used to realize force transmission.

[0036] When the above structure is implemented, when the first limiting wheel 10, the second limiting wheel 17 and the fixed wheel 20 are fully fitted with the spring piece 21, there is a certain gap between the first fixed pin block 23 and the third fixed pin block 29 and between the second fixed pin block 25 and the third fixed pin block 29, and the fixing hoop 26 is provided with a corresponding pin hole 27. The internal width of the pin hole 27 should be slightly smaller than the thickness of the first fixed pin block 23 and the third fixed pin block 29 as a whole and the second fixed pin block 25 and the third fixed pin block 29 as a whole. During the assembly process, a cold source or a heat source should be provided to make the above structure expand and contract to achieve interference assembly.

[0037] Combined with Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 The supporting steel frame 5 is provided with docking blocks 19 on the upper and lower sides, and a docking hole 14 matching the docking block 19 is provided at the top center of the connecting component 13. In order to ensure the stable support of the second limiting wheel bracket 24, a cushion block 16 is provided on the back of the second limiting wheel bracket 24 to fit the surface of the supporting steel frame 5. The top and bottom of the central bracket 4 are provided with positioning blocks 11, and positioning holes 12 are provided on both sides of the positioning block 11. Positioning rods 15 matching the positioning holes 12 are provided on both sides of the connecting component 13.

[0038] Combined with Figure 3 and attached Fig. 9 The inlet at the bottom end of the buffer elbow 7 extends to the river channel 2, and the top end is connected to a piston 28, and the free end of the piston 28 is fixedly connected to the free end of the one-way damper 8.

[0039] Attach Fig. 9 The one-way damper 8 should be a damper that only provides compression damping, so as to ensure that the piston 28 can return quickly to absorb the next impact.

[0040] In order to provide the outer side slope of the river channel 2 with the ability to resist instantaneous impact, the above structure can provide relative damping for the impact of water flow to a certain extent. When the water flow reaches the bend of the river channel 2, due to inertia, the water flow still retains its original direction of movement, and part of the water flow will enter the inlet of the buffer elbow 7 and enter the piston 28 along the buffer elbow 7. The water flow pushes the piston rod outward by inertia, and the spiral spring in the piston rod absorbs part of the impact. The damping provided by the one-way damper 8 connected to the piston rod continuously reduces the kinetic energy of the water in this process, thereby achieving the buffering of the water flow impact.

[0041] The present invention and its implementation methods are described above, and such description is not restrictive, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by it, and does not deviate from the purpose of the invention, and does not creatively design a structure and implementation method similar to the technical solution, they should all fall within the protection scope of the present invention.
