Description

Technical Field

[0001] The invention belongs to the technical field of reservoir design, and in particular relates to an open channel adaptive anti-seepage structure for a cross-fault reservoir. Background Art

[0002] With the continuous increase in reservoir open channel construction projects, more and more projects need to be constructed in areas with extremely complex geological conditions, especially in active fault areas. Active faults, with their unique dynamic characteristics such as creep and stick-slip, bring great challenges to the design and construction of reservoir open channels. These activities not only cause significant deformation of the surface, but also cause stress concentration, posing a serious safety threat to the anti-seepage structure.

[0003] The anti-seepage structure based on concrete or cement-based materials has been widely used in the anti-seepage treatment of reservoir open channels due to its high strength, high density and excellent durability. However, in active fault areas, due to the frequent and intense fault activities, these traditional anti-seepage structures are prone to tensile tearing and joint failure due to excessive tensile and shear forces, which seriously weakens their anti-seepage effect and endangers the safety of the structure. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses an adaptive anti-seepage structure for an open channel of a cross-fault reservoir.

[0014] The third anti-seepage component comprises from bottom to top a flexible anti-seepage layer, an expansion water-stopping layer, a composite waterproof module and a blocking layer.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The buffer area provided by the gap module of the present invention can adapt to the deformation and displacement caused by fault activity, thereby ensuring that the overall structure of the canal will not be damaged by fault activity; (2) The waterproof module, the protection unit and the anti-seepage components inside the present invention together constitute a multi-level anti-seepage system.

DETAILED DESCRIPTION

[0017] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0018] like Figure 1 , Figure 2 As shown, the present invention discloses an adaptive anti-seepage structure for an open channel of a cross-fault reservoir, comprising a support module 1, a channel module 2, a gap module and a support module filled with an anti-seepage component; The support module 1 is arranged on the surface of the canal wall and is used to support the canal wall; The channel module 2 is arranged on the surface of the support module 1 for water flow to pass through; The gap module is arranged between the channel module 2 and the support module 1 to provide a buffer area to adapt to the deformation and displacement caused by the fault activity; The support module is arranged in the gap module to absorb and disperse the energy of the fault activity through its own deformation and prevent the channel module 2 from water seepage.

[0019] Preferably, the gap module includes an air barrier layer and a groove 101 across the channel module 2; The air barrier layer is arranged between the channel module 2 and the support module 1; The groove 101 is formed on the surface of the channel module 2 and communicates with the air barrier layer. Figure 2 In the cross-sectional view shown, the bottom area of ​​the spacer layer is the same as the bottom area of ​​the channel module 2 , and the bottom area of ​​the groove 101 is smaller than the bottom area of ​​the spacer layer.

[0020] Preferably, the cross-fault reservoir open channel adaptive anti-seepage structure further includes a waterproof module 3; The waterproof module 3 is laid in the insulation layer to prevent moisture from penetrating into the supporting module 1 .

[0021] Preferably, the supporting module includes a base unit, a protection unit arranged in the air-insulating layer and the groove 101; The base unit is arranged on the surface of the waterproof module 3 to prevent moisture from penetrating into the supporting module 1; like Figure 3 As shown, the base unit includes a drainage board 41 and a limiting subunit; The anti-drainage board 41 is connected to the surface of the waterproof module 3 to prevent water from penetrating into the support module 1; The limiting subunit is arranged on the surface of the anti-drainage plate 41 and is clamped in the groove 101. Preferably, the limiting subunit includes at least one limiting block.

[0022] In Example 1, Figure 1 As shown, the groove 101 is U-shaped when viewed from the side, and the depth of the groove 101 decreases from the middle to both ends. The shape of the spacer layer matches the groove 101 and is also U-shaped when viewed from the side.

[0023] The limiting subunit includes a plurality of first U-shaped limiting blocks 42 and a second U-shaped limiting block 43 connected to the surface of the anti-drainage board 41. The anti-drainage board 41, the first U-shaped limiting blocks 42 and the second U-shaped limiting blocks 43 are all U-shaped when viewed from the side.

[0024] A U-shaped groove and a plurality of U-shaped limiting grooves are provided on one side of the channel module 2 in contact with the limiting subunit, for installing the drainage plate 41 and the first U-shaped limiting block 42 respectively. Figure 3 , Figure 2 As shown; the U-shaped groove and the multiple U-shaped limit grooves are all U-shaped when viewed from the side.

[0025] like Figure 2 , Figure 3 As shown, the second U-shaped limit block 43 is located in the groove 101, and the first U-shaped limit block 42 and the second U-shaped limit block 43 are both made of elastic material. The provision of the anti-drainage board 41, the first U-shaped limit block 42 and the second U-shaped limit block 43 can avoid the situation in which, when the anti-drainage board 41, the first U-shaped limit block 42 and the second U-shaped limit block 43 are not present, a gap is generated between the channel module 2 and the waterproof module 3 during the pulling process of the groove 101, resulting in water seepage.

[0026] The interior of the protection unit is filled with anti-seepage components, which are used to absorb and disperse the energy of fault activity through its own deformation and prevent water seepage from the channel module 2.

[0027] The protection unit includes a pipe arranged inside the groove 101; The upper end of the pipe is open, and the bottom end matches the top profile of the limiting subunit and is connected to the top of the limiting subunit; The side wall of the pipe is an uneven curved surface; The interior of the pipe is filled with a first anti-seepage component.

[0028] like Figure 3 As shown, in Example 1, a pipe located in the groove 101 is fixedly connected to the top of the second U-shaped limit block 43 , and the first anti-seepage component is a closed-hole plate 13 .

[0029] like Figure 3 , Figure 7 As shown, the pipeline includes a U-shaped arc plate 62 fixedly connected to the top of the second U-shaped limit block 43 and a pair of L-shaped side plates 61. The L-shaped side plates 61 are fixedly connected to the two ends of the U-shaped arc plate 62 and fit with the inner wall of the groove 101. The L-shaped side plates 61 are U-shaped when viewed from the side (that is, the same shape as the groove 101). Accordingly, the height of the side walls of the L-shaped side plates 61 is gradually reduced from the middle position toward the two ends. The L-shaped side plates 61 are provided to facilitate the installation of the closed-cell plate 13.

[0030] like Figure 3 As shown, the first anti-seepage component is a closed-cell plate 13 installed in the pipe. The closed-cell plate 13 is a foam plate. The bottom end and side walls of the closed-cell plate 13 are respectively adapted to the shapes of the bottom end and side walls of the pipe. When the groove 101 squeezes the L-shaped side plate 61, the closed-cell plate 13 can buffer the L-shaped side plate 61 to avoid water seepage.

[0031] In Example 1, the L-shaped side plate 61 is in an uneven wave shape. In Example 2, the L-shaped side plate 61 is in a straight surface shape, but its inner wall is provided with a wave-shaped arc plate, and the closed hole plate 13 matches the shape of the arc plate.

[0032] The present invention can disperse the pulling force to a wider area by setting the U-shaped arc plate 62, thereby reducing the stress level at any point on the L-shaped side plate 61. This dispersion effect is similar to the arch structure in the bridge, which can effectively resist the pressure from above or the pulling force from below. Therefore, the present invention can prevent the L-shaped side plate 61 from tearing and causing leakage when being pulled by setting the U-shaped arc plate 62. Furthermore, the U-shaped arc plate 62 is used in conjunction with the second U-shaped limit block 43, which can not only provide buffering when tearing, but also fix the installation position of the U-shaped arc plate 62.

[0033] The protection unit also includes a water stop groove; The groove of the water stop groove is clamped at the opening of the pipe, and the side walls of the water stop groove are provided with extension plates 72 at both ends, and the extension plates 72 are mounted on the top of the side walls of the pipe; in Example 1, the water stop groove is a U-shaped water stop groove. Figure 3 As shown, a slot matching the groove portion 71 of the U-shaped water stop groove is provided on the top of the obturator plate 13 , and the top of the obturator plate 13 is connected to the bottom of the extension plate 72 .

[0034] The present invention can limit the position of the obturator plate 13 by providing the L-shaped side plate 61 , the U-shaped arc plate 62 and the groove portion 71 of the U-shaped water stop groove, thereby preventing the obturator plate 13 from moving during use.

[0035] The groove portion 71 of the U-shaped water stop groove is filled with a second anti-seepage component, preferably, the second anti-seepage component is an asphalt hemp layer 5. Preferably, the height of the asphalt hemp layer 5 is set in a decreasing manner from the middle position to the two ends. The asphalt hemp layer 5 provided in the present invention is conducive to waterproofing and anti-corrosion of the inner cavity of the U-shaped water stop groove.

[0036] In Example 1, the U-shaped water stop groove is arranged above the pipe and is located in the groove 101. When the groove 101 is deformed, the U-shaped water stop groove, the pipe and the obturator plate 13 inside it can also be deformed accordingly. This deformation adaptability ensures the tight fit between the U-shaped water stop groove, the pipe and the obturator plate 13 and the groove 101, thereby effectively preventing water from leaking through the gap. The groove portion 71 of the U-shaped water stop groove is clamped on the obturator plate 13, and the extension plates 72 at both ends overlap the top of the L-shaped side plate 61.

[0037] Furthermore, the end 73 of the extension plate extends out of the groove 101 , and the end 73 is located inside the channel module 2 and is arranged in an inclined shape, with a height away from the groove end being higher than a height close to the groove end.

[0038] At the same time, in order to limit the extension plate 72 and prevent the extension plate 72 from being separated from the channel module 2 during the pulling process, a pair of grooves corresponding to the shape and position of the extension plate 72 are opened in the channel module 2. The pair of grooves are symmetrical and connected to the groove 101. In order to adapt to the groove 101, the depth of the groove portion 71 of the U-shaped water stop groove and the height of the extension plate 72 are both arranged to decrease from the middle position to the two ends.

[0039] The protection unit also includes a pair of mounting brackets and an elastic connection assembly; A pair of mounting frames are symmetrically connected to the extension plates at both ends of the U-shaped water stop groove, and a gap is provided between the pair of mounting frames, and the gap is used to fill the third anti-seepage component; The elastic connection assembly is arranged at the corresponding head end and tail end of a pair of mounting frames, and is used to connect the pair of mounting frames.

[0040] like Figure 4 As shown, the extending direction of the pair of mounting brackets is the same as that of the groove 101 .

[0041] In Example 1, Figure 3 , Figure 5 , Figure 6As shown, a pair of mounting frames are two L-shaped plates 81, and a pair of mounting frames formed by splicing the two L-shaped plates 81 are similar to a channel. In other embodiments, the plates 81 may also be straight plate structures. A pair of mounting frames are respectively fitted with the inner walls corresponding to the grooves 101, and a pair of mounting frames are U-shaped when viewed from the side. The bottom ends of a pair of mounting frames are integrated with the extension plates 72 on both sides, and the gap between the pair of mounting frames corresponds to the groove portion 71 of the U-shaped water stop groove, which is convenient for the asphalt hemp layer 5 to be installed in the U-shaped water stop groove. In order to adapt to the groove 101, the side wall heights of a pair of mounting frames are arranged to decrease from the middle position toward both ends.

[0042] like Figure 6 As shown, a pair of plates 81 are respectively provided with V-shaped plates 83 at both ends, and the free ends of the V-shaped plates 83 are fixedly connected with connecting plates 82, which are made of elastic material. The connecting plates 82 and the V-shaped plates 83 are provided to connect the two plates 81 together, and the elastic material can prevent the groove 101 from breaking the connecting plate 82 when being pulled. The pair of mounting frames of the present invention make the installation and fixation of the third anti-seepage component more convenient.

[0043] The pipe and a pair of mounting frames of the present invention are both formed by splicing a plurality of parts, rather than being integrally formed, which is conducive to enhancing the deformation adaptability of the present invention when the groove 101 is pulled, and is convenient for installation and disassembly; further, the support module of the present invention is formed by stacking a plurality of parts and corresponding impermeable components, and this design allows the stress to be dispersed to a plurality of parts, rather than concentrated on a single part, thereby improving the overall stability and load-bearing capacity and fault repair. Furthermore, the stacked parts are in close contact and support each other, thereby increasing the contact area and improving the overall stability of the structure; the impermeable components of the present invention can be effectively filled between the various parts to form a continuous impermeable barrier. These impermeable components usually have good elasticity and sealing properties, can fit tightly on the surface of the component, and prevent liquid or gas from leaking out of the gap. Even if a certain layer of the impermeable components is damaged or aged, the impermeable components of other layers can still continue to function, ensuring the safety and reliability of the system.

[0044] The third anti-seepage component comprises from bottom to top a flexible anti-seepage layer 9, an expansion water-stopping layer, a composite waterproof module and a blocking layer.

[0045] In Example 1, the sealing layer is a polyurea sealing layer 12; the swelling waterstop layer is a swelling waterstop strip 10; the composite waterproof module is a composite anti-seepage layer 11; the flexible anti-seepage layer 9, the swelling waterstop strip 10, the composite anti-seepage layer 11 and the polyurea sealing layer 12 are all connected to the two side walls of a pair of mounting frames. The flexible anti-seepage layer 9 is fixedly connected to the top of the asphalt hemp layer 5. The flexible anti-seepage layer 9 is made of geosynthetics with high elasticity and durability, such as high-density polyethylene HDPE geomembrane, composite geotextile or bentonite pad material. The top of the flexible anti-seepage layer 9 is fixedly connected with an expansion waterstop strip 10. When the leaking water contacts the expansion waterstop strip 10, it will expand, thereby preventing the leaking water from moving further downward. The top of the expansion waterstop strip 10 is fixedly connected with a composite anti-seepage layer 11. The composite anti-seepage layer 11 is made of flexible anti-seepage material to enhance the adaptability and deformation resistance of the anti-seepage layer. The top of the composite anti-seepage layer 11 is fixedly connected with a polyurea sealing layer 12. The polyurea sealing layer 12 is flush with the surface of the channel module 2. The polyurea sealing layer 12 can be anti-corrosive, wear-resistant, and waterproof. The most important thing is to resist impact force, thereby preventing cracks from occurring in the groove 101 during extrusion or tearing.

[0046] The construction process of the present invention is as follows: 1. Confirm the position of the reservoir fault, level it, then construct the support module 1 at the reservoir wall position corresponding to the reservoir fault, and apply the air-insulating layer, and then lay the waterproof module 3 at the air-insulating layer; 2. Fix the U-shaped arc plate 62 to the second U-shaped limit block 43, and fix the L-shaped side plate 61 to the drainage plate 41, and then place the closed hole plate 13 between the pair of L-shaped side plates 61, so that the bottom end of the closed hole plate 13 contacts the U-shaped arc plate 62; 3. Insert the lower end of the U-shaped water stop groove into the slot, and the U-shaped water stop groove and a pair of mounting frames are fixed at the same time; 4. Pour the asphalt hemp layer 5 into the groove part 71 of the U-shaped water stop groove through the gap between a pair of mounting frames, and then install the flexible waterproof layer 9, the expansion water stop strip 10 and the composite waterproof layer 11 in sequence between the pair of mounting frames. Finally, apply the polyurea sealing layer 12 on the composite waterproof layer 11 to cover it, and paint the surface of the connection between the groove 101 and the channel module 2.

[0047] Compared with the prior art, the present invention has the following beneficial effects: (1) The buffer area provided by the gap module of the present invention can adapt to the deformation and displacement caused by fault activity, thereby ensuring that the overall structure of the canal will not be damaged by fault activity; (2) The waterproof module, the protection unit and the anti-seepage components inside the present invention together constitute a multi-level anti-seepage system. The protection unit can effectively prevent water from penetrating into the channel module and the support module through its own deformation and ability to absorb fault activity energy, thereby ensuring the anti-seepage performance of the reservoir open channel; (3) The grooves of the present invention are connected to the air-insulating layer, forming a more complex anti-seepage network, which not only increases the diversity of anti-seepage paths, but also improves the overall strength and stability of the anti-seepage structure; during fault activity, the grooves can act like a "seat belt" to tightly fix the anti-seepage components on the channel module to prevent them from falling off or being damaged due to stress and deformation; (4) The design elements of the present invention, such as the drainage plates and grooves, not only help prevent water from penetrating, but also guide water out, optimizing the drainage system, which helps to reduce the water pressure inside the reservoir open channel and further improve the stability and safety of the structure; (5) The present invention uses a variety of deformable and adjustable components, such as pipes, water stop grooves and elastic connection components, which can be flexibly adjusted according to the characteristics of different fault activities to adapt to various complex geological conditions; (6) The present invention adopts a modular design, which allows for easy installation and disassembly, and fully considers convenience in design and construction. At the same time, the connection method between the components is also designed to be relatively simple, reducing the difficulty of construction and maintenance.
