[0021] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the invention is further described below in conjunction with specific embodiments. Examples

[0022] Referring to Figures 1-4, a novel inter-pile sealing and water-stopping device for construction includes a steel plate 1, and connecting components and fixing components disposed on the steel plate 1. The connecting components are used to connect two adjacent steel plates 1 together, and the fixing components are used to fix the two connected steel plates 1 together to the pile column 101. The connecting components include a set of first connecting rods 2 disposed on one side of the surface of the steel plate 1, and a set of second connecting rods 3 disposed on the other side of the surface of the steel plate 1. Each first connecting rod 2 is L-shaped and extends outward from the steel plate 1. Each end of each first connecting rod 2 is provided with a U-shaped connecting plate 4. Each connecting plate 4 has a through hole 5. Each second connecting rod 3 has a through hole 5. The connecting rod 3 is L-shaped and extends outward from the other side of the steel plate 1. Each end of the second connecting rod 3 is provided with an insert plate 6, and the insert plate 6 has a through hole 7. The edges of two adjacent steel plates 1 overlap and are spliced ​​together. Each insert plate 6 is inserted into the connecting plate 4, and the through hole 5 is aligned with the through hole 7 and bolts are inserted to fasten them together. The fixing assembly includes a fixing plate 8. A U-shaped rail groove 9 is provided on one edge of the fixing plate 8, and the edge of the steel plate 1 is embedded in the U-shaped rail groove 9. Multiple fixing holes 10 are provided on the other side surface of the fixing plate 8. In this embodiment of the invention, the connecting plate 4 is a double-layer plate structure, and the insert plate 6 is a single-layer plate structure. As shown in Figure 3, the length of the first connecting rod 2 is greater than that of the second connecting rod 3. The length of the connecting rod 3; and when using this leak-stopping and water-stopping device, firstly, select leak-stopping steel plates 1 of different specifications and sizes according to the required distance between piles to be leaked. Then, according to the width of the two steel plates 1 spliced ​​together and the width of the fixing plate 8, drill pre-embedded installation holes on the pile column 101, drive expansion bolts into the installation holes, and then install and fix the fixing plate 8 on the expansion bolts. After that, install the two steel plates 1, which are pre-spliced ​​together. Each insert plate 6 is inserted into each connecting plate 4 one by one, so that the through hole 7 on the insert plate 6 is aligned with the fixing hole 10 on the connecting plate 4 one by one. Then, insert the bolts, and then hoist the two pre-spliced ​​steel plates 1 simultaneously. The edge of the steel plate 1 is along the U-shaped rail groove 9. Once the device is slid in, the leak-stopping and water-sealing device can be installed. Cement can then be poured into the gap between the steel plate 1 and the pile 101 to seal the leak. After the cement hardens, the leak-stopping and water-sealing device can be removed, completing its use. Because all components of this leak-stopping and water-sealing device are prefabricated, they can be quickly assembled and used, improving the efficiency of inter-pile water sealing. Furthermore, the steel plate 1 panel uses an insert-type structure, allowing it to be removed and reused after the inter-pile water sealing is completed, saving costs and effectively solving the problems of long construction time and material waste associated with traditional methods. This significantly improves the efficiency of inter-pile leakage sealing construction.

[0023] Referring to Figures 1-4, each fixing hole 10 is arranged in a "+" shape; the fixing plate 8 is also arranged with "+" shaped fixing holes 10. When drilling the installation hole on the pile column 101, considering that there is a steel reinforcement skeleton inside the pile column 101, in order to avoid damaging the steel reinforcement skeleton when drilling the installation hole, the position of the installation hole to be drilled can be adjusted up and down or left and right, which has high flexibility and protects the strength of the pile column 101.

[0024] Referring to Figures 1-4, a rubber pad 11 is provided inside the U-shaped rail groove 9, and the rubber pad 11 is arranged along the length direction of the U-shaped rail groove 9. The rubber pad 11 is used to fill the gap between the U-shaped rail groove 9 and the steel plate 1. The rubber pad 11 is bonded to the U-shaped rail groove 9, and the edges of the steel plate 1 are rounded to prevent the sharp edges of the steel plate 1 from squeezing and damaging the rubber pad 11 during the process of the steel plate 1 sliding into the U-shaped rail groove 9. Recesses are provided at the overlapping parts of the edges of two adjacent steel plates 1, and the recesses are arranged along the length direction of the steel plate 1. The system is configured such that a rubber strip 12 is filled within the recess, and the rubber strip 12 is used to fill the gap between two adjacent steel plates 1; a rubber plate 13 is provided on the other side of each fixing plate 8, the rubber plate 13 is arranged along the length direction of the fixing plate 8, and the rubber plate 13 is used to fill the gap between the fixing plate 8 and the pile column 101; during the cement pouring process, a vibrator is used to compact the cement while pouring, and during compaction, considering the cement seepage and waste, some gaps are sealed to reduce cement waste. Example

[0025] Referring to Figures 4-7, in contrast to Embodiment 1, as another embodiment of the present invention, a sealing plate 14 is provided below the steel plate 1. The edge of the sealing plate 14 opposite to the pile column 101 is wavy, and a lifting mechanism is provided below the sealing plate 14. The lifting mechanism includes a base plate 15, a top column 16 is provided on the base plate 15, a hydraulic rod is provided inside the top column 16, and a top block 17 is provided at the output end of the hydraulic rod. The top block 17 rests on the bottom of the sealing plate 14. Considering that the water seepage and leakage point on the pile column 101 may be located above it, it is necessary to erect a support on the ground. The supporting structure supports the entire leak-stopping and water-sealing device, ensuring its stability during the pouring process. Specifically, in this embodiment, the lifting mechanism of the supporting structure drives the hydraulic rod to push the lifting block 17 after the steel plate 1 is installed on the fixed plate 8. The lifting block 17 then pushes the sealing plate 14. At this time, the sealing plate 14 not only seals the gap between the bottom of the leak-stopping and water-sealing device and the pile column 101, but also supports and holds the entire leak-stopping and water-sealing device, distributing the upward force of the hydraulic rod evenly on the leak-stopping and water-sealing device, thus ensuring the stability of the leak-stopping and water-sealing device after support.

[0026] Referring to Figures 8 and 9, the upper end of the top column 16 is provided with an extension rod 18. The extension rod 18 extends upward and is placed in the gap between the first connecting rod 2 and the steel plate 1. The extension rod 18 is mainly used to constrain the stability of the hydraulic rod. That is, when the hydraulic rod pushes the leak-stopping device, it is necessary to ensure that the upward force of the hydraulic rod tends to be vertical and upward. The extension rod 18 can constrain the direction of the upward force of the hydraulic rod. As shown in Figure 5, the extension rod 18 on the right slides into the gap between the second connecting rod 3 and the steel plate 1, and the extension rod 18 on the left slides into the gap between the first connecting rod 2 and the steel plate 1, ensuring that the lifting mechanism stably supports the leak-stopping device upward.

[0027] Referring to Figures 4 and 5, an L-shaped support plate 19 is provided between the end of the sealing plate 14 and the fixing plate 8. The horizontal part of the support plate 19 supports the lower surface of the sealing plate 14, and the vertical part of the support plate 19 has a connecting hole opposite to the fixing hole 10. The support plate 19 is used to assist the lifting mechanism. After the fixing plate 8 is installed and fixed on the pile column 101, the sealing plate 14 is pre-assembled below the fixing plate 8. At this time, the support plate 19 can be used to fix the fixing plate 8 with the expansion bolts at the bottom of the fixing plate 8, and the sealing plate 14 is pre-supported. When the lifting mechanism is assembled later, there is no need to consider the assembly of the sealing plate 14, which makes the entire leak-stopping and water-sealing device more convenient to use.

[0028] Referring to Figures 8 and 9, each extension rod 18 has multiple slots 20 on the same side, with the slots 20 arranged along the length of the extension rod 18. A crossbar 21 is installed within two slots 20 at the same height of two adjacent extension rods 18. The end of the crossbar 21 is embedded in the slot 20, and multiple support frames 22 are provided on the crossbar 21. Each support frame 22 includes a support leg 23 resting on the ground and a support column 24 resting on the crossbar 21. The end of the support column 24 is shaped like the letter "C" and is fastened between two limiting blocks 25 on the crossbar 21. The lifting mechanism provides an upward force for the leak-stopping device, while the support frames 22 are used for... The water device provides horizontal compressive force, improving the stability between the steel plate 1 and the pile 101. Specifically, after the lifting mechanism is assembled, the support frame 22 is assembled, the support column 24 is locked between two adjacent limiting blocks 25, and then the support leg 23 is fixed to the ground. Anchor rods can be used to fix the support leg 23 to the ground. The crossbar 21 cooperates with the latch 20 on the extension rod 18, so that the horizontal support force can be effectively applied to different height positions on the steel plate 1. The cooperation between the support column 24 and the limiting block 25 allows the horizontal support force to be evenly distributed on the steel plate 1. Even when the steel plate 1 is subjected to the vibration force of the vibrator, the steel plate 1 can still be assembled on the pile 101 in a stable state.

[0029] Referring to Figures 7-9, each support frame 22 is provided with two support columns 24, one at the bottom and one at the top. The bottom support column 24 is fixed to the support frame 22, while the top support column 24 is slidably connected to the support frame 22. The height of the top support column 24 can be adjusted to accommodate the support of steel plates 1 of different sizes. For example, for some steel plates 1 with a longer length, the horizontal support force is higher than the ground. The height of the top support column 24 can be adjusted. Specifically, the top of the support frame 22 is a rectangular steel tube, and a screw 26 is rotatably connected inside the rectangular steel tube. A sliding hole opened along the side wall of the rectangular steel tube of the support column 24 passes through it. The screw 26 is threadedly connected to the support column 24. By rotating the screw 26, the height of the support column 24 is adjusted, thereby accommodating crossbars 21 of different heights and thus providing horizontal support for steel plates 1 of different sizes.

[0030] Referring to Figures 11 and 12, a pin 27 is inserted between the through hole 5 and the through hole 7. A limiting rod 28 is provided at the end of the pin 27. The axis of the limiting rod 28 is parallel to the axis of the pin 27, and the limiting rod 28 is inserted on one side of the end of the second connecting rod 3. The pin 27 can be directly inserted into the through hole 5 and the through hole 7 without the need for a threaded bolt. At the same time, the limiting rod 28 can further constrain the connection strength and stability between the connecting plate 4 and the insert plate 6.

[0031] Referring to Figures 11 and 12, each pin 27 has two adjacent limiting rods 28 at its end, and the two adjacent limiting rods 28 are inserted on both sides of the end of the second connecting rod 3. Two adjacent limiting rods 28 are provided on the same pin 27. The pin 27 passes through the through hole 5 and the through hole 7, while the two adjacent limiting rods 28 are inserted on both sides of the end of the second connecting rod 3, that is, inserted on the back of the insert plate 6, and also placed in front of the opening of the connecting plate 4. This serves to prevent the insert plate 6 from separating from the connecting plate 4, and also to constrain the pin 27, indirectly increasing the contact area between the pin 27 and the insert plate 6 and the connecting plate 4, thereby improving stability.

[0032] Working principle: When using this leak-stopping and water-sealing device, firstly, select leak-stopping steel plates 1 of different specifications and sizes according to the required distance between piles to be leaked. Then, based on the width of the two steel plates 1 spliced ​​together and the width of the fixing plate 8, drill pre-embedded installation holes on the pile column 101, insert expansion bolts into the installation holes, and then install and fix the fixing plate 8 on the expansion bolts. Next, install the two steel plates 1, which are pre-spliced ​​together. Each insert plate 6 is inserted into each connecting plate 4, so that the through hole 7 on the insert plate 6 is aligned with the fixing hole 10 on the connecting plate 4. Then, insert the bolts. Then, hoist the two pre-spliced ​​steel plates 1 simultaneously. The edges of the steel plates 1 slide along the U-shaped rail groove 9. Once the steel plate 1 and pile 101 are joined, the installation of the leak-stopping device is complete. Cement is then poured into the gap between the steel plate 1 and the pile 101 to seal the leak. After the cement hardens, the leak-stopping device is removed, and its use is complete. Because all components of this leak-stopping device are prefabricated, they can be quickly assembled and used, improving the efficiency of inter-pile water sealing. Furthermore, the steel plate 1 panel uses an insert-type structure, allowing it to be removed and reused after the inter-pile water sealing is completed, saving costs and effectively solving the problems of long construction time and material waste associated with traditional methods. This significantly improves the efficiency of inter-pile leakage sealing.
