Description

Technical Field

[0001] This utility model relates to the field of sliding gate technology, and in particular to a sliding track water-stopping repair structure and water-stopping system. Background Technology

[0002] In engineering, gates are commonly used as water-blocking components at passageways. Gates have two states: open and closed. When open, they allow passage for personnel or goods; when closed, they act as water-blocking structures. In some scenarios, such as within the construction dock for immersed tunnel sections, the dock includes a prefabrication area and a floating area. The prefabrication area is used to prefabricate the immersed tunnel sections, while the floating area is used to lift and transport them out of the dock. During the transfer of the immersed tunnel sections, the prefabricated sections need to be moved from the prefabrication area to the floating area, and then water is injected into the floating area until the sections float. To enclose the floating area, water-blocking structures need to be installed around it. Furthermore, to allow the immersed tunnel sections to move from the prefabrication area to the floating area, engineers devised a sliding gate between the prefabrication area and the floating area.

[0003] A sliding gate consists of a gate and a sliding track for the gate to slide. The sliding track typically includes a concrete foundation, a steel sliding plate (pad), and a slider. The gate's support beams are located on the steel sliding plate, and there is a slider between them, allowing the support beams to slide along the slider. After construction, technicians discovered leakage at the bottom of the sliding track area. Inspection revealed that other locations were well sealed, and the leakage occurred between the concrete foundation and the steel sliding plate (pad). The concrete foundation and the steel sliding plate (pad) are made of different materials, and their contact surfaces are difficult to fit tightly, resulting in a seepage path between them. Because of the leakage, the water-stopping effect in the sliding track area is insufficient, and the floating area cannot be effectively protected after the gate is closed. Demolition and reconstruction would be costly, and without a new water-stopping structure, the water-stopping effect after reconstruction might not be better. Utility Model Content

[0004] The purpose of this utility model is to overcome the problem in the prior art that leakage occurs at the bottom of the existing sliding track area, resulting in the sliding track area failing to meet the requirements for water-stopping effect and the inability to effectively protect the floating area after the gate is closed, and to provide a sliding track water-stopping repair structure and water-stopping system.

[0050] Example 1

[0051] like Figure 1 As shown, the existing sliding track bottom structure includes the original concrete foundation 1 and the pad 2 set on the top surface of the original concrete foundation 1. A support beam 7 is set above the pad 2, and a slider structure 71 is set between the support beam 7 and the pad 2. The bottom of the support beam 7 has a groove that matches the slider structure 71. The original concrete foundation 1 and the pad 2 are made of different materials. The interface between the different materials is difficult to fit tightly, which makes it easy for seepage channels for water to seep into the interface. Several seepage channels are connected to form a seepage path.

[0052] To improve the water-stopping effect between the original concrete foundation 1 and the pad 2, such as Figures 2 to 4 As shown, this embodiment provides a sliding track water-stopping repair structure. An extension block 3 is poured and installed on one side of the original concrete foundation 1. The extension block 3 is connected to the original concrete foundation 1. A second water-stop plate 5 is provided on the top surface of the extension block 3. The second water-stop plate 5 is connected to the pad plate 2.

[0053] The extension block 3 can be formed by concrete pouring. The concrete structure itself has good waterproof performance and can effectively prevent water from flowing through. The extension block 3 can be set on the water-facing side of the original concrete foundation 1 and extend along the length of the original concrete foundation 1. The extension block 3 is connected to the side of the original concrete foundation 1, and the two can be combined to form a new foundation. A second waterstop 5 is provided above the extension block 3. The second waterstop 5 is a waterproof structure. One end of the second waterstop 5 can be connected to the pad 2 to form a new pad. Compared with the original foundation, the new foundation is wider and the seepage path formed between the new foundation and the pad 2 / second waterstop 5 above it is longer. It is more difficult for water to seep through from this point, which effectively improves the water-stopping effect of the overall structure.

[0054] Furthermore, in this embodiment, a first waterstop plate 4 is embedded in the extension block 3, the upper part of the first waterstop plate 4 extends out of the top surface of the extension block 3, and a second waterstop plate 5 is connected to the first waterstop plate 4.

[0055] The first waterstop plate 4 can be an impermeable structure pre-embedded in the extension block 3. The upper part of the first waterstop plate 4 extends out of the top surface of the extension block 3 and is connected to the second waterstop plate 5 set on the top surface of the extension block 3, so that the first waterstop plate 4 can cut off the seepage path between the extension block 3 and the second waterstop plate 5, thereby cutting off the seepage path between the extension block 3 and the second waterstop plate 5, which can greatly improve the water-stopping effect.

[0056] The first waterstop plate 4 and the second waterstop plate 5 can be made of impermeable steel, wood or polymer materials.

[0057] The sliding track water-stopping repair structure described in this embodiment, by setting an extension block 3 and a second water-stop plate 5, with the extension block 3 connected to the original concrete foundation 1 and the second water-stop plate 5 connected to the pad 2, effectively increases the width of the foundation and the pad, thereby extending the seepage path between the foundation and the pad, which is beneficial to improving the water-stopping effect; by embedding a first water-stop plate 4 in the extension block 3 and having the upper part of the first water-stop plate 4 extend out of the extension block 3 and connect with the second water-stop plate 5, the seepage path between the extension block 3 and the second water-stop plate 5 can be cut off, thereby greatly improving the water-stopping effect.

[0058] The sliding track water-stopping repair structure described in this embodiment can achieve rapid water-stopping repair of the existing sliding track bottom structure with relatively low cost, and significantly improve the water-stopping effect to meet the water-stopping requirements.

[0059] In some implementations, the original concrete foundation 1 is also called the steel gate front sliding track beam; the pad 2 is also called the steel sliding plate.

[0060] In some embodiments, a first cushion layer 11 formed by mortar pouring is provided between the pad 2 and the original concrete foundation 1. The first cushion layer 11 can level the top surface of the original concrete foundation 1 to facilitate the installation of the pad 2. The first cushion layer 11 can also fill the uneven structure on the opposite surface of the original concrete foundation 1 and the pad 2, which helps to reduce the seepage channels between the pad 2 and the original concrete foundation 1, making it more difficult for water to seep in from between the original concrete foundation 1 and the pad 2.

[0061] Preferably, a second pad 31 is provided between the extension block 3 and the second waterstop 5. The second pad 31 is connected to the first pad 11 and is also formed by mortar pouring.

[0062] The second pad 31 can level the top surface of the extension block 3 and fill the uneven structure on the opposite surface of the extension block 3 and the second waterstop 5. The second pad 31 can be connected to the first pad 11. The second pad 31 also facilitates the adjustment of the height of the second waterstop 5 so that it can be connected to the pad 2.

[0063] When pouring the second cushion layer 31, a small piece can be chiseled off the side of the first cushion layer 11 to expose the mortar surface inside, so that the newly poured second cushion layer 31 can be more tightly connected with the first cushion layer 11, thereby improving the water-stopping effect between the two.

[0064] Both the first cushion layer 11 and the second cushion layer 31 can be formed by high-strength epoxy grouting; preferably, the thickness of the first cushion layer 11 is 22-27mm and the thickness of the cushion plate 2 is 18-22mm.

[0065] In some embodiments, the first waterstop plate 4 is vertically arranged, with one surface of the first waterstop plate 4 facing the original concrete foundation 1.

[0066] In terms of spatial structure, the first waterstop plate 4 can extend along the length direction of the extension block 3 to improve the waterstopping effect of the extension block 3 throughout its length; in terms of cross-section, such as Figure 2 and Figure 3 As shown, the first waterstop plate 4 is vertically arranged to facilitate its connection with the second waterstop plate 5. One side of the first waterstop plate 4 faces the original concrete foundation 1, so that the first waterstop plate 4 can effectively cut off the seepage path between the extension block 3 and the second waterstop plate 5.

[0067] Those skilled in the art will understand that the extension block 3 is usually formed by concrete pouring, and the first waterstop 4 is usually made of impermeable steel or wood. A new seepage path may be formed at the junction of the extension block 3 and the first waterstop 4. In order to reduce the risk of water seepage caused by the new seepage path, this embodiment preferably sets a third waterstop 6 on the side of the first waterstop 4 away from the original concrete foundation 1. The third waterstop 6 is connected to the first waterstop 4 and protrudes from the surface of the first waterstop 4.

[0068] The third waterstop 6 can extend along the length of the extension block 3; the third waterstop 6 can not only extend the seepage path between the first waterstop 4 and the extension block 3, but also change the direction of the seepage path, making it more difficult for water to pass through. The length of the first waterstop 4 embedded in the extension block 3 can be determined according to the water-stopping needs. In principle, the longer the embedment length, the better the water-stopping effect. To further improve the water-stopping effect, multiple third waterstops 6 can be vertically spaced on the side of the first waterstop 4.

[0069] In some embodiments, the second waterstop 5 is horizontally arranged, with one end of the second waterstop 5 sealed to the first waterstop 4 and the other end sealed to the pad 2.

[0070] The second waterstop 5 is sealed to the first waterstop 4 and the pad 2, forming a sealed structure above the extension block 3 and the original concrete foundation 1, reducing water seepage from that point and thus improving the overall water-stopping effect.

[0071] Specifically, the second waterstop 5 has a first end face and a second end face that are arranged opposite to each other. The first end face is connected to the surface of the first waterstop 4, and the second end face is connected to the pad 2.

[0072] Preferably, the first waterstop plate 4, the second waterstop plate 5, and the pad plate 2 are all made of steel; the first waterstop plate 4 and the second waterstop plate 5 are welded together, and the second waterstop plate 5 and the pad plate 2 are welded together.

[0073] In some embodiments, the side of the original concrete foundation 1 is provided with a roughened surface 12, and the extension block 3 is in contact with the roughened surface 12; by roughening the side of the original concrete foundation 1, the extension block 3 can be more closely attached to the original concrete foundation 1.

[0074] In some embodiments, a rebar anchor 13 is provided on the original concrete foundation 1. The rebar anchor 13 extends out of the side of the original concrete foundation 1 and the extended part is located inside the extension block 3. The rebar can be anchored on the side of the original concrete foundation 1. The rebar anchor can improve the connection strength between the extension block 3 and the original concrete foundation 1 and reduce the probability of water-stopping failure due to separation of the extension block 3 and the original concrete foundation 1.

[0075] The anchoring component 13 is preferably a fully threaded M16 bolt; the anchoring depth is preferably 22-27cm, more preferably 25cm; the anchoring spacing is preferably 0.75-0.95m, more preferably 0.84m.

[0076] Example 2

[0077] The sliding track water-stopping repair structure provided in this embodiment is based on embodiment 1. The difference between embodiment 1 and embodiment 1 is that the second water-stopping plate 5 and the pad plate 2 are integrally formed.

[0078] The second waterstop 5 and the pad 2 are integrally formed, which can improve the water-stopping effect between the two and reduce the probability of water leakage due to loose connection. Specifically, during construction, the original pad 2 can be removed and replaced with a wider new pad. The new pad takes on the functions of the pad 2 and the second waterstop 5 and is welded to the first waterstop 4.

[0079] More preferably, reinforcing bars or small steel plates are added to the larger gaps between the new pad and the first waterstop plate at four different locations for welding to ensure the welding quality achieves the water-stopping effect.

[0080] Example 3

[0081] This embodiment provides a sliding track water-stopping system, including a sliding track water-stopping repair structure as described in Embodiment 1 or 2, wherein the extension block 3 is set on the water-facing side of the original concrete foundation 1.

[0082] In some embodiments, the sliding track water-stopping system also includes a support beam 7 located above the pad 2, a slider structure 71 is provided between the pad 2 and the support beam 7, the bottom of the support beam 7 is provided with a groove that cooperates with the slider structure 71, the slider structure 71 can be fixedly connected to the pad 2, the support beam 7 can slide along the slider structure 71, and the steel gate is connected to the support beam 7.

[0083] Preferably, the water-facing side of the support beam 7 is also provided with a first anchor 8 and a waterstop structure 9. The lower end of the first anchor 8 is provided with a pad 2 and anchored into the original concrete foundation 1. The waterstop structure 9 seals and connects the first anchor 8 and the support beam 7.

[0084] More preferably, the waterstop structure 9 is detachably connected to the first anchor 8 and the waterstop structure 9 is detachably connected to the support beam 7. When the steel gate is in the closed position, water-stop sealing can be achieved by installing the waterstop structure 9. Before opening the steel gate, the waterstop structure 9 is removed to facilitate the sliding of the steel gate.

[0085] More preferably, pressure plate assemblies are respectively provided on the pad 2 and the support beam 7, and the two sides of the waterstop structure 9 are pressed and fixed by the pressure plate assemblies.

[0086] Preferably, it also includes a second anchor, which is laterally spaced from the first anchor 8, and the second anchor is located near the back side of the pad 2.

[0087] The sliding track water-stopping system described in this embodiment, by using the sliding track water-stopping repair structure as described above, enables rapid water-stopping repair of existing sliding tracks at a lower cost, and can significantly improve the water-stopping effect to meet water-stopping requirements.

[0088] Example 4

[0093] A4. Install the second waterstop 5, which connects the upper part of the first waterstop 4 and the pad 2.

[0094] In step A1, the surface of the original concrete foundation 1 on the water-facing side is roughened and reinforced with steel bars.

[0095] In step A2, a third waterstop plate 6 can be pre-embedded at the same time.

[0096] In step A4, the second waterstop plate 5 can be welded to the first waterstop plate 4 and the pad plate 2.

[0097] The sliding track water-stopping repair method described in this embodiment can quickly repair existing water-stopping structures with fewer construction steps and significantly improve the water-stopping effect to meet water-stopping requirements.

[0098] Example 5

[0099] This embodiment provides a method for repairing water-stopping mechanisms on sliding tracks, based on the water-stopping repair structure for sliding tracks described in Embodiment 2, including the following steps:

[0100] S1. Remove the pad 2, chisel away all or part of the first pad layer 11, and install rebar on the top surface of the original concrete foundation 1.

[0101] The sides of the original concrete foundation 1 were roughened and reinforced with steel bars.

[0102] An extension block 3 is poured on the side of the original concrete foundation 1, and a first waterstop plate 4 is pre-embedded in the extension block 3.

[0103] S2. Install a new pad, which replaces pad 2 and the second waterstop 5. A gap is formed between the new pad and the original concrete foundation 1 and extension block 3.

[0104] The new pad is provided with perforations and vent holes, and the connecting bars implanted on the top surface of the original concrete foundation 1 are perforated.

[0105] The gap between the perforation and the connecting rib is filled with weld;

[0106] Weld the new pad and the first waterstop plate 4;

[0107] S3. Grout the gap between the new pad and the original concrete foundation 1 and extension block 3 to form a new pad layer, which replaces the first pad layer 11 and the second pad layer 31.

[0108] In step S1, a third waterstop plate 6 can be pre-embedded simultaneously; the implanted connecting bar is preferably a fully threaded M16 bolt; the bar planting depth is preferably 22-27cm, and more preferably 25cm; the bar planting spacing is preferably 0.75-0.95m, and more preferably 0.84m.

[0109] In step S2, the material of the new pad can be the same as that of pad 2, such as steel plate, and the new pad serves the functions of pad 2 and the second waterstop 5.

[0110] By grouting into the voids to form a new cushion layer, the uneven structure between the new cushion plate and the opposite surfaces of the original concrete foundation 1 and extension block 3 can be filled more fully, thereby improving the water-stopping effect.

[0111] The sliding track water-stopping repair method described in this embodiment improves the integrity of pad 2 and the second water-stop plate 5 by replacing pad 2 and the second water-stop plate 5 with a new pad, and replaces the first pad 11 and the second pad 31 with a new pad layer, thereby enhancing the water-stopping effect. By installing rebar on the top surface of the original concrete foundation 1 and passing the connecting rebar through the perforations in the new pad, the connection strength between the new pad and the original concrete foundation 1 can be improved, reducing the probability of misalignment between the new pad and the original concrete foundation 1 during the sliding of the support beam 7.

[0112] Example 6

[0113] This embodiment uses a specific construction scenario as an example. In this scenario, the bottom structure of the existing sliding track includes a steel gate sliding track beam and a steel sliding plate set on the steel gate sliding track beam. High-strength epoxy grout is poured between the steel sliding plate and the steel gate sliding track beam. A steel gate front support leg beam is set above the steel sliding plate. A steel gate bottom slider structure is set between the steel gate front support leg beam and the steel sliding plate. A waterstop structure is set on one side of the steel gate front support leg beam.

[0114] Includes the following steps:

[0115] The first step is to dismantle the old steel sliding plate and its upper structure;

[0116] The second step is to remove the grout layer under the steel slide plate to a depth of about 25mm.

[0117] The third step is to drill holes and install rebar in the steel gate track beam according to the opening position of the steel sliding plate. M16 bolts with full threads are used for rebar installation. The rebar installation depth is 25cm and the rebar spacing is 0.84m. The steel sliding plate is divided into 6m sections.

[0118] The fourth step is to install the new steel plate after the rebar is installed. The elevation of one side of the steel plate is adjusted using leveling nuts, and the other side is leveled with the assistance of lifting equipment. The elevation of the steel plate is controlled at 2.650m ± 5mm. After leveling, the steel plate is welded to fill the reserved holes. The steel plate is welded to the first waterstop plate 4 of the extended block 3. In some places with larger gaps, steel bars or small steel plates are added and welded to ensure that the welding quality achieves the waterstop effect.

[0119] The fifth step is to grout the bottom of the steel slide plate after it is installed. The grouting is carried out through the air vents reserved in the steel slide plate.
