Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and hydropower engineering, and in particular to a water-stopping structure for a water conservancy engineering project. Background Art

[0002] Water conservancy and hydropower projects refer to various types of projects built to regulate and utilize natural water resources. Water conservancy and hydropower projects are generally composed of dams, power station buildings and ships. The anti-seepage and water-stopping structures used in water conservancy and hydropower projects are an important part of building the water conservancy and hydropower project drainage system. The use of anti-seepage and water-stopping structures used in water conservancy and hydropower projects can prevent the water conservancy and hydropower project structures from being damaged due to long-term contact with water bodies, thereby avoiding major accidents in water conservancy and hydropower projects.

[0003] The patent document with the published announcement number CN218291836U provides an anti-seepage and water-stopping structure for water conservancy and hydropower projects. By setting up water retaining blocks, waterproof boards and waterproof work cloths, the purpose of preventing liquid from penetrating into the main body of the dam is achieved as much as possible, thereby avoiding the collapse of the main body of the dam due to long-term moisture, thereby ensuring the safety of the main body of the dam. The set buzzer can serve as a reminder for maintenance when leakage occurs, and the water pump can pump out the liquid inside the water storage tank when seepage occurs, thereby ensuring the safety of the main body of the dam.

[0004] The most important thing during the construction of the above structure is to accurately set the relatively large water retaining blocks. However, it is usually difficult to ensure that such large water retaining blocks can be accurately installed and ensure the tightness of the connection between them and the dam body during construction. Even if the above requirements can be met, it will greatly increase the construction difficulty and greatly extend the construction period, which is time-consuming and labor-intensive. Therefore, a water-stopping structure for water conservancy projects is proposed to address the above problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present application provides a water-stopping structure for a water conservancy project, which overcomes the deficiencies of the prior art and aims to solve the problem that the setting of large-sized water retaining blocks is difficult to operate during construction and takes a long time to complete.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0007] A water-stopping structure for a hydraulic project comprises a dam body and an anti-seepage baffle arranged on the rear end surface thereof, the dam body and the anti-seepage baffle being fixedly connected by a connecting piece, and a foam filling layer is filled between the dam body and the anti-seepage baffle, adjacent anti-seepage baffles are airtightly connected by a side splicing structure, a top cover structure is provided at the top of the anti-seepage baffle and the upper cover of the dam body, the connecting piece comprises an anchoring part buried in the dam body and an external connecting part, the anchoring part is composed of a rotating section, a restraining section and a waterproof ring arranged in sequence from the inside to the outside, and the connecting part comprises a connecting rod, and a snap-on convexity is fixedly provided on the outer wall at the end of the connecting rod.

[0008] By adopting the above technical scheme, the difficulty of operation can be greatly reduced and the construction period can be significantly shortened during construction, saving time and labor. It is only necessary to fit the anti-seepage baffle plate to the dam body and fix it with connecting parts, and then pour the foam filling layer into the gap. In particular, due to the special structural form of the connecting part, after the connecting rod is fully inserted, it is only necessary to rotate it so that the snap-fitting protrusion is snap-fitted with the end face of the constraint section to achieve the function of fixed connection. There is no need to connect it with bolts, which effectively shortens the time spent. In addition, the side splicing structure can solve the problem of easy water seepage at the splicing of the anti-seepage baffle plate, and its installation method is also very simple and quick.

[0009] As a preferred technical solution of the present application, a rotation groove is opened in the middle of the rotating section, a through groove is opened in the middle of the constraint section and the waterproof ring, and the connecting rod is provided with a rod section with a snap-fit ​​protrusion, and the cross-sectional size of the rod section is consistent with the cross-sectional size of the through groove.

[0010] By adopting the above technical solution, the connecting rod can smoothly pass through the constraint section and the waterproof ring when the snap-on protrusion is facing upward, so that the snap-on protrusion can be fully extended into the rotating groove. At this time, rotating the connecting rod can make the snap-on protrusion rotate in the rotating groove. When the snap-on protrusion deviates from the groove due to rotation, the connecting rod can no longer be pulled out, thereby playing a fixing role.

[0011] As a preferred technical solution of the present application, the front end of the connecting rod extends out of the anti-seepage baffle and the end is fixedly connected to a rotating wheel, and an elastic gasket is provided on the connecting rod outer sleeve between the rotating wheel and the anti-seepage baffle.

[0012] By adopting the above technical solution, when the connecting rod is fully inserted, the elastic gasket will be squeezed by the rotating wheel, which will also apply an external thrust to the rotating wheel, making it difficult to rotate, thereby ensuring that the connecting rod is not easily rotated out due to the action of water flow.

[0013] As a preferred technical solution of the present application, the rear end face of the anti-seepage baffle is fixedly provided with a plurality of symmetrically arranged support tubes, the connecting rod is slidably arranged in the support tubes, the end of the support tubes is in close contact with the waterproof ring and can completely cover the through groove, and the rear end face of the anti-seepage baffle is fixedly provided with a plurality of support plates.

[0014] By adopting the above technical solution, a gap of equal width can be reserved between the anti-seepage baffle and the dam body, providing necessary conditions for filling the foam filling layer.

[0015] As a preferred technical solution of the present application, a limiting groove is provided in the center of the upper side of the end of the support tube, the groove body size of the limiting groove is consistent with the size of the snap-in protrusion, and when the snap-in protrusion moves to the bottom of the limiting groove, the plane where the connecting rod end is located coincides with the plane where the end of the support tube is located.

[0016] By adopting the above technical solution, when installing and adjusting the position of the anti-seepage baffle, the end of the connecting rod can be completely retracted into the supporting tube and will not extend outward to interfere with the adjustment work.

[0017] As a preferred technical solution of the present application, the side splicing structure includes a clamping strip fixedly arranged at the edge of the front end surface of the anti-seepage baffle plate, and the outer sleeves of the clamping strips on two adjacent anti-seepage baffle plates are provided with a C-shaped constraint strip, and a waterproof adhesive layer is attached to the inner wall of the C-shaped constraint strip.

[0018] By adopting the above technical solution, the splicing gaps between adjacent anti-seepage baffles can be covered in a manner of C-shaped constraint strips and clamping strips, thereby effectively improving the anti-seepage capacity of the splicing joints.

[0019] As a preferred technical solution of the present application, the top cover structure includes a cover plate, a plug-in shaft is fixedly arranged on the lower end surface of the cover plate, a plug-in hole is opened on the upper end surface of the anti-seepage baffle, and a groove with a size matching the cover plate is opened on the upper end surface of the rear end of the dam body.

[0020] By adopting the above technical solution, the top cover structure can be fixedly installed, and the foam filling layer can be covered after being poured, which plays a role of beauty and protection.

[0021] As a preferred technical solution of the present application, a mounting slot is provided at the bottom of the dam body, the bottom of the anti-seepage baffle is inserted into the mounting slot, and a waterproof adhesive layer is attached to the inner wall of the mounting slot.

[0022] By adopting the above technical solution, the installation slots can be used to play a positioning and temporary restraining role during the initial installation of the anti-seepage baffle. After the anti-seepage baffle is fixed, the installation slots can also provide a stable bottom restraint, thereby improving the firmness and stability of the installation of the anti-seepage baffle.

[0023] The beneficial effects of the present application are as follows: during construction, it is only necessary to fit the anti-seepage baffle plate to the dam body and fix it with connecting parts, and then pour the foam filling layer into the gap, which can greatly reduce the difficulty of operation and significantly shorten the construction period, saving time and effort, and the anti-seepage measures composed of the anti-seepage baffle plate and the foam filling layer can also play a dual anti-seepage role. In particular, due to the special structural form of the connecting part, after the connecting rod is fully inserted, it is only necessary to rotate it so that the snap-fitting protrusion is snap-fitted with the end face of the constraint section to achieve the effect of fixed connection, without the need for bolt connection, effectively shortening the time spent. In addition, the side splicing structure can solve the problem of easy water seepage at the splicing of the anti-seepage baffle plate, and its installation method is also very simple and quick.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Reference Figure 1 , Figure 4The waterproof structure of a water conservancy project comprises a dam body 1 and an anti-seepage baffle 2 arranged on the rear end surface thereof. The dam body 1 and the anti-seepage baffle 2 are fixedly connected by a connecting piece 3, and the dam body 1 and the anti-seepage baffle 2 are filled with a foam filling layer 4. The adjacent anti-seepage baffles 2 are airtightly connected by a side splicing structure 5. The top of the anti-seepage baffle 2 and the upper cover of the dam body 1 are provided with a top cover structure 6. By adopting the above technical scheme, the operation difficulty can be greatly reduced and the construction period can be significantly shortened during construction, which saves time and effort. It is only necessary to fit the anti-seepage baffle 2 to the dam body 1 and fix it with a connecting piece 3, and then pour the foam filling layer 4 into the gap, which can greatly reduce the operation difficulty and significantly shorten the construction period, which saves time and effort. The anti-seepage measures jointly formed by the anti-seepage baffle 2 and the foam filling layer 4 can also play a dual anti-seepage role. In addition, the side splicing structure 5 can solve the problem of easy water seepage at the splicing of the anti-seepage baffle 2, and its installation method is also very simple and quick.

[0032] Reference Figure 2 The connecting member 3 includes an anchoring part buried in the dam body 1 and an external connecting part. The anchoring part is composed of a rotating section 31, a constraint section 32 and a waterproof ring 33 arranged in sequence from the inside to the outside. The connecting part includes a connecting rod 34. The outer wall at the end of the connecting rod 34 is fixedly provided with a snap-on protrusion 35. Due to the special structural form of the connecting member 3, after the connecting rod 34 is fully inserted, it only needs to be rotated so that the snap-on protrusion 35 is snap-fitted with the end face of the constraint section 32 to achieve the function of fixed connection. There is no need to connect by bolts, which effectively shortens the time spent.

[0033] Reference Figure 2 A rotation groove 311 is provided in the middle of the rotation section 31, and a through groove 321 is provided in the middle of the constraint section 32 and the waterproof ring 33. The cross-sectional size of the rod section of the connecting rod 34 provided with the clamping protrusion 35 is consistent with the cross-sectional size of the through groove 321. By adopting the above technical scheme, the connecting rod 34 can smoothly pass through the constraint section 32 and the waterproof ring 33 when the clamping protrusion 35 is facing upward, so that the clamping protrusion 35 is completely extended into the rotation groove 311. At this time, rotating the connecting rod 34 can make the clamping protrusion 35 rotate in the rotation groove 311. When the clamping protrusion 35 deviates from the through groove 321 due to rotation, the connecting rod 34 can no longer be pulled out, thereby playing a fixing role.

[0034] Reference Figure 2 The front end of the connecting rod 34 extends out of the anti-seepage baffle 2 and the end is fixedly connected to a rotating wheel 36. An elastic gasket 37 is provided on the outer sleeve of the connecting rod 34 between the rotating wheel 36 and the anti-seepage baffle 2. By adopting the above technical solution, when the connecting rod 34 is fully inserted, the elastic gasket 37 will be squeezed by the rotating wheel 36, and it will also apply an external thrust to the rotating wheel 36, making it difficult to rotate, thereby ensuring that the connecting rod 34 is not easily rotated out due to the action of water flow.

[0035] Reference Figure 2-3, a plurality of symmetrically arranged support tubes 21 are fixedly provided on the rear end surface of the anti-seepage baffle 2, and a connecting rod 34 is slidably arranged in the support tube 21. The end of the support tube 21 is in close contact with the waterproof ring 33 and can completely cover the through groove 321. A plurality of support plates 22 are fixedly provided on the rear end surface of the anti-seepage baffle 2. This structural form can reserve equal-width gaps between the anti-seepage baffle 2 and the dam body 1, providing necessary conditions for the filling of the foam filling layer 4. In addition, a limiting groove 38 is provided in the center of the upper side of the end of the support tube 21. The groove body size of the limiting groove 38 is consistent with the size of the clamping protrusion 35, and when the clamping protrusion 35 moves to the bottom of the limiting groove 38, the plane where the end of the connecting rod 34 is located coincides with the plane where the end of the supporting tube 21 is located. By adopting the above technical scheme, when installing and adjusting the position of the anti-seepage baffle 2, the end of the connecting rod 34 can be completely retracted in the supporting tube 21, and will not extend outward to interfere with the adjustment work.

[0036] Reference Figure 5 The side splicing structure 5 includes a clamping strip 51 fixedly arranged at the edge of the front end surface of the anti-seepage baffle 2. The clamping strips 51 on two adjacent anti-seepage baffles 2 are outer-coated with a C-shaped constraint strip 52, and a waterproof adhesive layer is attached to the inner wall of the C-shaped constraint strip 52. By adopting the above technical scheme, the splicing gap between the adjacent anti-seepage baffles 2 can be covered in a manner of clamping the clamping strip 51 with the C-shaped constraint strip 52, thereby effectively improving the anti-water seepage capacity of the splicing joint.

[0037] Reference Figure 5 The top cover structure 6 includes a cover plate 61, a plug-in shaft 62 is fixedly provided on the lower end surface of the cover plate 61, a plug-in hole 63 is provided on the upper end surface of the anti-seepage baffle 2, and a groove whose size matches the cover plate 61 is provided on the upper end surface of the rear end of the dam body 1. By adopting the above technical scheme, the top cover structure 6 can be fixedly installed, and the foam filling layer 4 can be covered after the pouring is completed, which plays a role in beauty and protection.

[0038] Reference Figure 1 An installation slot 11 is provided at the bottom of the dam body 1, and the bottom of the anti-seepage baffle 2 is inserted into the installation slot 11. A waterproof adhesive layer is attached to the inner wall of the installation slot 11. By adopting the above technical scheme, the installation slot 11 can play a role in positioning and temporary restraint during the initial installation of the anti-seepage baffle 2. After the anti-seepage baffle 2 is fixed, the installation slot 11 can also provide a stable bottom constraint, thereby improving the firmness and stability of the installation of the anti-seepage baffle 2.

[0039] Working principle: When installing the anti-seepage baffle 2, first completely retract the end of the connecting rod 34 into the support tube 21, then completely insert the bottom of the anti-seepage baffle 2 into the installation slot 11, and make the connecting rod 34 align with the rotating section 31, the constraint section 32 and the waterproof ring 33 with the snap-on protrusion 35 facing upward, then push the connecting rod 34 to be continuously inserted through the rotating wheel 36 until the snap-on protrusion 35 is completely inserted into the rotating groove 311, at this time, rotating the connecting rod 34 can make the snap-on protrusion 35 rotate in the rotating groove 311, when the snap-on protrusion 35 deviates from the groove 321 due to rotation, the connecting rod 34 can no longer be pulled out, playing a fixing role, so that the anti-seepage baffle 2 can be fixed on the dam body 1, this connection method does not require bolt connection, can effectively shorten the time spent, and then pouring the foam filling layer 4 into the gap can roughly complete the entire construction, thereby greatly reducing the difficulty of operation during construction and significantly shortening the construction period, saving time and effort.
