Description

Technical Field

[0001] This invention relates to the field of diaphragm wall technology, and more specifically, to a seepage treatment system for ultra-deep diaphragm wall construction in water-rich soft soil areas. Background Technology

[0002] A diaphragm wall is a foundation engineering project where a trenching machine is used on the ground to excavate a narrow trench along the perimeter of the deep excavation project, under the condition of mud wall protection. After cleaning the trench, a steel cage is suspended in the trench, and then concrete is poured in using the tremie method to form a unit trench segment. This process is carried out segment by segment to build a continuous reinforced concrete wall underground, which serves as a structure for water interception, seepage prevention, load-bearing, and water retention.

[0003] In the construction of diaphragm walls, the excavation of the diaphragm wall is carried out in sections, and the joints of the diaphragm wall are connected by a connecting structure, such as an I-beam joint. However, for deep, soft soil layers with high water content, water seepage is still likely to occur at the joints of the diaphragm wall. Summary of the Invention

[0017] Firstly, the present invention, through the first extension plate and the second extension plate, can automatically extend the I-beams into the concrete layer when concrete is poured in the reinforcing cage. After the concrete has solidified, the first extension plate and the second extension plate increase the contact surface between the I-beams and the channel section, increase the water flow path required for leakage, and further ensure the sealing between the channel section and the I-beams, so that the underground continuous wall has a better anti-seepage effect.

[0018] Secondly, by incorporating a triggering component, this invention can automatically control the displacement of the first and second extension plates into the concrete layer at corresponding positions during concrete pouring within the trench section. This eliminates the need for manual operation, reduces the workload of workers, and improves the effectiveness of the waterproof structure.

[0019] Thirdly, by providing structures such as a third extension plate and a fourth extension plate, when the second extension plate is inserted into the concrete layer, the third extension plate and the fourth extension plate automatically extend out of the second extension plate and insert into the concrete layer. This increases the contact surface between the second extension plate and the concrete layer, further increasing the water flow path required for leakage and ensuring the sealing between the I-beam and the channel section.

[0020] Fourth, by incorporating a reinforcing plate and a second support block, the present invention can automatically provide support to the interior of the vertical cavity of the I-beam when the extension component is inserted into the concrete layer. This minimizes the problem of the I-beam being squeezed and deformed by the soil layer on the side closest to the vertical cavity, thus ensuring the overall strength of the I-beam.

[0021] Fifth, by setting up structures such as the first support block and the first support groove, the present invention can form a support effect in the transverse cavity, which can avoid the problem of the soil layer squeezing the I-beam and causing the part near the transverse cavity to sink, thus further ensuring the strength of the I-beam.

[0022] Sixth, by incorporating a locking structure and limiting components, the present invention can fix the sliding plate, minimizing the possibility of movement of the sliding plate, further ensuring the support and fixation effect inside the horizontal and vertical cavities, as well as the stability of the extended structure.

[0036] Please see Figure 1-7 The present invention provides the following technical solutions:

[0037] Specifically, it refers to a seepage treatment system for ultra-deep underground continuous wall construction in water-rich soft soil areas, including a trench 1, multiple sections 2 set in the trench 1, and I-beams 3 set between two sections 2. Each section 2 includes multiple vertical reinforcing bars 21, multiple horizontal reinforcing bars 22, multiple vertical reinforcing bars 23, and a pouring pipe 24. The vertical reinforcing bars 21, horizontal reinforcing bars 22, and vertical reinforcing bars 23 are bundled into a reinforcing cage, and the pouring pipe 24 is installed in the reinforcing cage. In use, the reinforcing cage and the pouring pipe 24 are placed into the trench 1, and then the I-beams 3 are installed on one side of the reinforcing cage. Concrete is then poured into the reinforcing cage through the pouring pipe 24. After the concrete fills the space in the trench 1 and solidifies, it forms section 2. The setting of the I-beams 3 can create a sealing effect between two adjacent sections 2.

[0038] Multiple transverse cavities 31 are formed in each of the two transverse plates of the I-beam 3. These cavities 31 are arranged vertically and parallel to each other on the transverse plates of the I-beam 3. Two first extension plates 311 are slidably connected to the bottom wall of each cavity 31. The two first extension plates 311 are located on the left and right sides of the vertical plate of the I-beam 3, respectively. The side of the first extension plate 311 away from the vertical plate of the I-beam 3 slides through the outer surface of the I-beam 3 and extends into the groove section 2. Multiple second extension plates 312 are arranged inside the transverse cavities 31, located within the first extension plates 311. The other side of the second extension plates 312 slides through the outer surface of the I-beam 3 and extends into the groove section 2. Baffles 313 are provided on both the left and right surfaces of the second extension plates 312 to limit their movement. Multiple first rotating plates 314 are hinged between the first extension plates 311 and the second extension plates 312. The initial position is contracted into the H-beam 3. This way, when the H-beam 3 is installed on the reinforcing cage, the first extension plate 311 and the second extension plate 312 will not contact the reinforcing cage, thus affecting the installation of the H-beam 3. When the pouring pipe 24 pours concrete into the reinforcing cage, it controls the first extension plate 311 to move outward. At the same time, the first rotating plate 314 will exert a thrust on the second extension plate 312, causing the second extension plate 312 to move outward until the baffle 313 contacts the inner wall of the transverse cavity 31. This allows both the first extension plate 311 and the second extension plate 312 to extend into the uncured concrete. After the concrete cures, the first extension plate 311 and the second extension plate 312 increase the contact surface between the H-beam 3 and the channel section 2, increasing the water flow path required for leakage, further ensuring the sealing between the channel section 2 and the H-beam 3, so that the underground continuous wall has a better seepage prevention effect.

[0039] The second extension plate 312 is hollow inside, and an external extension component 315 is provided inside the second extension plate 312. The external extension component 315 includes a first push plate 3151, which slides inside the second extension plate 312. A plurality of third extension plates 3152 are provided on the side surface of the first push plate 3151 facing away from the first extension plate 311. The other side of the third extension plates 3152 slides through the outer surface of the second extension plate 312. Two second push plates 3153 are provided on the left and right sides of the first push plate 3151. Multiple fourth extension plates 3154 are provided on one side surface of the first push plate 3151. The other side of the fourth extension plate 3154 also slides through the second extension plate 312. When the second extension plate 312 extends to the uncured concrete layer, the third extension plate 3152 and the fourth extension plate 3154 extend out of the outside of the second extension plate 312 and into the concrete layer. In this way, the contact surface between the second extension plate 312 and the concrete layer is increased, which further increases the water flow path required for leakage and ensures the sealing between the I-beam 3 and the channel section 2.

[0040] A limiting slide rod 3159 is slidably sleeved on the first push plate 3151. A first spring 31510 is movably sleeved on the outer surface of the limiting slide rod 3159 between the first push plate 3151 and the inner wall of the second extension plate 312. When the first spring 31510 is not compressed, the first spring 31510 will push the first push plate 3151, so that the initial position of the third extension plate 3152 and the fourth extension plate 3154 is retracted into the second extension plate 312.

[0041] The baffle 313 is also hollow inside and communicates with the interior of the second extension plate 312. A rotating shaft 3156 is rotatably connected to the bottom wall of the baffle 313. A movable rotating plate 3157 is fitted onto the outer surface of the rotating shaft 3156. One side of the movable rotating plate 3157 extends into the second extension plate 312. A pressing rod 3158 is provided on the side of the movable rotating plate 3157 facing the first push plate 3151, contacting the first push plate 3151. A communicating groove 31512 is formed on the side of the baffle 313 facing away from the first extension plate 311, communicating with its interior. A pressing plate 31511 is provided on the inner wall of the transverse cavity 31 facing the communicating groove 31512. The pressing plate 31511 and the communicating groove 31512 are at the same horizontal position. When the second extension plate 31... When the second extension plate 312 moves out of the I-beam 3, the baffle 313 moves synchronously with the second extension plate 312. When the extrusion plate 31511 moves into the baffle 313 through the connecting groove 31512, the extrusion plate 31511 will exert a thrust on one side of the movable rotating plate 3157, causing the movable rotating plate 3157 to rotate around the rotating shaft 3156 as the rotation point. As a result, the extrusion rod 3158 will exert a thrust on the first push plate 3151, causing the third extension plate 3152 and the fourth extension plate 3154 to extend into the second extension plate 312. With the above structure, the displacement of the third extension plate 3152 and the fourth extension plate 3154 can be automatically controlled when the second extension plate 312 moves, without the need for additional control, thus ensuring the effectiveness and convenience of the mechanism.

[0042] Both sides of the vertical plate of the I-beam 3 are provided with triggering components for controlling the displacement of the first extension plate 311. Multiple triggering components are arranged vertically in parallel. Each triggering component includes a trigger plate 33, which is positioned between the vertical plate of the I-beam 3 and the slot section 2. Multiple sets of vertical cavities 32, arranged vertically in parallel, are formed within the vertical plate of the I-beam 3. Each set of vertical cavities 32 consists of two cavities, located on the left and right sides of the vertical plate of the I-beam 3. Each vertical cavity 32 is connected to two horizontal cavities 31. A push rod 321 is provided on the surface of the trigger plate 33 near the I-beam 3. The other end of the push rod 321 slides through the vertical cavity 32. A connecting rod is provided at the end of the push rod 321 within the vertical cavity 32. A tension spring 328 is movably sleeved on the push rod 321 between the connecting plate 322 and the inner wall of the vertical cavity 32. Therefore, when the tension spring 328 is not affected by tension, it will exert tension on the connecting plate 322, causing the connecting plate 322 to be on the side closer to the inner wall of the vertical cavity 32. In this way, the trigger plate 33 is on the side away from the vertical plate of the I-beam 3. When concrete is poured through the pouring pipe 24, the concrete in the trench 1 is gradually filled, so that the concrete can exert a pushing force on the trigger plate 33, causing the trigger plate 33 to move towards the side closer to the I-beam 3 until the trigger plate 33 contacts the vertical plate of the I-beam 3. At the same time, the push rod 321 pushes the connecting plate 322 to move, and the tension spring 328 is stretched.

[0043] The front and rear sides of the trigger plate 33 are in contact with the inner sides of the two horizontal plates of the I-beam 3, and the upper and lower trigger plates 33 are also in contact with each other. At the same time, the thickness of the trigger plate 33 is greater than the displacement distance of the trigger plate 33. In this way, when the lower trigger plate 33 is squeezed and displaced by the poured concrete, no gap will be formed between the upper and lower trigger plates 33. This avoids the problem of concrete flowing into the space between the trigger plate 33 and the I-beam 3, which would prevent the trigger plate 33 from being displaced, thus ensuring the stability of the trigger component.

[0044] Two sliding plates 323 are slidably connected to the bottom wall of the vertical cavity 32. The two sliding plates 323 are located on the front and rear sides of the connecting plate 322. The side of the sliding plate 323 away from the connecting plate 322 extends into the horizontal cavity 31. A fourth rotating plate 324 is hinged between the connecting plate 322 and the sliding plate 323. A control plate 325 is provided on the side of the sliding plate 323 facing the first extension plate 311. Multiple fifth rotating plates 326 are hinged between the control plate 325 and the sliding plate 323. The side of the control plate 325 away from the connecting plate 322 extends into the horizontal cavity 31 and connects with the first extension plate 311. When pushed... When rod 321 pushes connecting plate 322 to move, fourth rotating plate 324 will exert a thrust on sliding plate 323, causing sliding plate 323 to move to one side of transverse cavity 31. At the same time, fifth rotating plate 326 will exert a thrust on control plate 325, causing control plate 325 to push first extension plate 311 into the concrete layer. Through the above structure, when pouring concrete in groove section 2, the first extension plate 311 and second extension plate 312 at the corresponding positions can be automatically controlled to move into the concrete layer without manual operation, reducing the workload of workers and improving the effectiveness of the waterproof structure.

[0045] Multiple reinforcing plates 3231 are provided on the side of the sliding plate 323 facing away from the control plate 325. The other side of the reinforcing plates 3231 is hinged to the inner wall of the vertical cavity 32. Multiple circular grooves 3232 are formed on the surface of the sliding plate 323 near the reinforcing plates 3231. A rotating circular plate 3233 is rotatably connected in the circular grooves 3232. One side of the rotating circular plate 3233 extends out of the outer surface of the sliding plate 3233 through the circular grooves 3232. Movable sliding grooves 3234 are formed on the rotating circular plate 3233, respectively extending out of the opposite sides of the rotating circular plate 3233. The reinforcing plates 3231 are close to the rotating circular plate 3231. One side of the 233 extends into the movable slide groove 3234 and slides within the movable slide groove 3234. An extension groove 3235 is provided on the inner wall of the circular groove 3232. A locking structure for locking the reinforcing plate 3231 is provided in the extension groove 3235. When the sliding plate 323 moves, the reinforcing plate 3231 rotates synchronously, which drives the rotating circular plate 3233 to rotate within the circular groove 3232. At the same time, the reinforcing plate 3231 slides within the movable slide groove 3234. When the sliding plate 323 stops moving, one side of the reinforcing plate 3231 moves into the extension groove 3235 through the movable slide groove 3234.

[0046] Multiple second support blocks 3251 are provided on the surface of the control plate 325 facing the vertical cavity 32. Multiple second support grooves 3252 adapted to the second support blocks 3251 are provided on the inner wall of the vertical cavity 32 near the second support blocks 3251. The other side of the second support block 3251 extends into the second support groove 3252 and slides in the second support groove 3252. Therefore, when the control plate 325 is displaced, the second support block 3251 is displaced in the second support groove 3252. Through the above-mentioned setting of the reinforcing plate 3231 and the second support block 3251, a support effect can be formed in the vertical cavity 32 of the I-beam 3, which avoids the problem of the side of the I-beam 3 near the vertical cavity 32 being squeezed and deformed by the soil layer as much as possible, and ensures the overall strength of the I-beam 3.

[0047] The locking structure includes a movable shaft 32351, the lower end of which is rotatably connected to the bottom wall of the extension groove 3235. A limiting plate 32352 is sleeved on the outer surface of the movable shaft 32351. Two parallel support plates 32354 are provided on the inner wall of the extension groove 3235 near the limiting plate 32352. A connecting slide rod 32355 is provided between the two support plates 32354. The outer surface of the connecting slide rod 32355 is slidably sleeved. A sliding sleeve 32356 is provided, and a second spring 32358 is movably sleeved on the outer surface of the connecting sliding rod 32355 between the sliding sleeve 32356 and the support plate 32354. A pusher plate 32357 is hinged between the sliding sleeve 32356 and the limiting plate 32352. A limiting groove 32353 adapted to the limiting plate 32352 is opened on the side of the reinforcing plate 32352 facing the limiting plate 32352. Therefore, when the reinforcing plate 3231 is displaced... When the reinforcing plate 3231 enters the extension groove 3235, it presses against the limiting plate 32352, causing the limiting plate 32352 to rotate around the movable shaft 32351. Simultaneously, the pushing plate 32357 pushes the sliding sleeve 32356 to slide on the connecting rod 32355, and the second spring 32358 is compressed and retracted by the sliding sleeve 32356. When the sliding plate 323 stops moving, the reinforcing plate 3231 rotates to a vertical position. At this time, the limiting plate 32352 moves to one side of the limiting groove 32353, so the second spring 32358 releases the thrust, pushing the rotating plate 32357 to push the limiting plate 32352 to rotate into the limiting groove 32353. In this way, the limiting plate 32352 restricts the reinforcing plate 3231, making it impossible for the reinforcing plate 3231 to move out of the extension groove 3235, further ensuring the supporting effect of the reinforcing plate 3231 on the vertical plate of the I-beam 3.

[0048] On the side of the first extension plate 311 facing away from the second extension plate 312, a plurality of first support blocks 3111 are provided. On the inner wall of the transverse cavity 31 near the first support blocks 3111, a plurality of first support grooves 3112 adapted to the first support blocks 3111 are provided. The other side of the first support block 3111 extends into the first support groove 3112 and slides within the first support groove 3112. A third rotating plate 3113 is hinged between the first support block 3111 and the first extension plate 311. When the first extension plate 311 moves outward, the third rotating plate 3113 will exert a pushing force on the first support block 3111, causing the first support block 3111 to move within the first support groove 3112. When the first extension plate 311 stops moving, the first support block 3111 is completely displaced into the first support groove 3112. This method can provide support within the transverse cavity 31, minimizing the problem of soil compression causing depressions near the transverse cavity 31, and further ensuring the strength of the I-beam 3.

[0049] A limiting component 327 is provided on one side of the sliding plate 323 located within the transverse cavity 31. The limiting component 327 includes a limiting block 3271, which is disposed on the side of the sliding plate 323 located within the transverse cavity 31. A limiting groove 3272 adapted to the limiting block 3271 is formed on the inner wall of the transverse cavity 31 facing the limiting block 3271. An internal cavity 3273 is formed within the limiting block 3271. A positioning block 3274 is disposed within the internal cavity 3273, which slides through the side of the limiting block 3271 on one side. The side of the positioning block 3274 outside the limiting block 3271 is set as a right-angled trapezoid. An internal plate 3275 that slides within the internal cavity 3273 is disposed on the side of the positioning block 3274 located within the internal cavity 3273. A third spring is provided between the internal plate 3275 and the internal cavity 3273. The inner wall of the spring 3276 and the limiting groove 3272 is provided with a positioning groove 3277 that is adapted to the positioning block 3274. When the sliding plate 323 moves, the limiting block 3271 moves synchronously. When the positioning block 3274 contacts the groove corner of the limiting groove 3272, the positioning block 3274 is forcefully retracted into the inner cavity 3273, and at the same time the third spring 3276 is compressed. When the sliding plate 323 stops moving, the limiting block 3271 is completely displaced into the limiting groove 3272. At this time, the positioning block 3274 is displaced into the positioning groove 3277 under the push of the third spring 3276, thereby completing the fixation of the sliding plate 323 and minimizing the problem of the sliding plate 323 moving. This further ensures the support and fixation effect inside the horizontal cavity 31 and the vertical cavity 32, as well as the stability of the extended structure.

[0050] The working principle of the seepage treatment system for ultra-deep underground continuous wall construction in water-rich soft soil areas provided by this invention is as follows:

[0051] Step 1: Tie the vertical steel bars 21, horizontal steel bars 22 and vertical steel bars 23 into a steel cage, and install the pouring pipe 24 in the steel cage. Place the steel cage and the pouring pipe 24 into the trench 1, and then install the I-beam 3 on one side of the steel cage. At this time, pour concrete into the steel cage through the pouring pipe 24.

[0052] In the second step, when concrete is poured through the pouring pipe 24, the concrete in the trench 1 is gradually filled, so that the concrete can exert a thrust on the trigger plate 33, causing the trigger plate 33 to move closer to the side of the I-beam 3 until the trigger plate 33 contacts the vertical plate of the I-beam 3. At the same time, the push rod 321 pushes the connecting plate 322 to move, and the tension spring 328 is stretched. When the push rod 321 pushes the connecting plate 322 to move, the fourth rotating plate 324 will exert a thrust on the sliding plate 323, causing the sliding plate 323 to move to the side of the transverse cavity 31. At the same time, the fifth rotating plate 326 will exert a thrust on the control plate 325.

[0053] In the third step, the control plate 325 pushes the first extension plate 311 into the concrete layer, and the first rotating plate 314 will exert a thrust on the second extension plate 312, causing the second extension plate 312 to move outward until the baffle 313 contacts the inner wall of the transverse cavity 31, so that both the first extension plate 311 and the second extension plate 312 extend into the uncured concrete.

[0054] In the fourth step, when the second extension plate 312 moves out of the I-beam 3, the baffle 313 moves synchronously with the second extension plate 312. When the extrusion plate 31511 moves into the baffle 313 through the connecting groove 31512, the extrusion plate 31511 will exert a thrust on one side of the movable rotating plate 3157, causing the movable rotating plate 3157 to rotate around the rotating shaft 3156 as the rotation point. As a result, the extrusion rod 3158 will exert a thrust on the first push plate 3151, causing the third extension plate 3152 and the fourth extension plate 3154 to extend into the second extension plate 312 and into the concrete layer.
