Abstract
Description
Technical Field
[0001] This application relates to the field of tunnel construction technology, and in particular to a waterproofing treatment method, system, terminal and storage medium for tunnel expansion joints. Background Technology
[0002] Expansion joints are structural gaps left in the building to prevent tunnels from cracking or being damaged due to factors such as temperature changes, uneven settlement of the foundation, or earthquakes.
[0003] In related technologies, during construction, a continuous gap needs to be left in advance at a designated location according to the design drawings to completely or partially disconnect the main structure. Subsequently, in order to protect the gap and maintain the building's function, a meticulous construction process is carried out: first, flexible padding materials such as foam rods are filled into the gap, and then high-performance sealant is used to seal it to achieve waterproofing and airtightness, thus obtaining an expansion joint.
[0004] The aforementioned technologies still result in expansion joints that are insufficient in terms of waterproofing. Summary of the Invention
[0005] To improve the waterproofing of tunnel expansion joints, this application provides a waterproofing treatment method, system, terminal, and storage medium for tunnel expansion joints.
[0006] In a first aspect, this application provides a method, system, terminal, and storage medium for waterproofing tunnel expansion joints, employing the following technical solution: A method for waterproofing tunnel expansion joints, comprising: The concrete section is formed by pouring concrete, and the concrete section adopts a centrally embedded waterstop. The concrete section is composed of a first concrete section and a second concrete section, and an expansion joint is provided between the first concrete section and the second concrete section. The expansion joint was filled with supporting material. A water collection box is installed on the surface of the expansion joint, the water collection box is embedded in the expansion joint, and the edge of the water collection box is sealed and fixed to the concrete part; The backwater surface of the expansion joint is sealed. A waterproof isolation layer is provided on the water-facing side of the expansion joint; A protective layer is provided on the waterproof isolation layer.
[0007] By adopting the above technical solutions, the expansion joint is effectively sealed by pouring concrete and installing an embedded waterstop. Supporting materials are used to fill the expansion joint to prevent it from widening. A water collection box is embedded in the expansion joint and sealed in place to collect and drain seepage water, preventing water accumulation. The backwater side is sealed to prevent water leakage from the inside. A waterproof isolation layer is installed on the water-facing side to directly block external water pressure. A protective layer protects the waterproof layer from damage, thereby comprehensively improving the waterproof performance of the tunnel expansion joint and ensuring its long-term waterproof reliability.
[0008] Optionally, a first fixing frame is provided, wherein the first fixing frame has a first recess; The first side of the embedded waterstop is placed inside the first recess. The first concrete section is formed by pouring concrete, so that the first concrete section covers the first fixing frame and the first side of the embedded waterstop. A second fixing bracket is provided, and the second fixing bracket has a second recess; The second side of the embedded waterstop is disposed within the second recess; The second concrete section is formed by pouring concrete to cover the second fixing frame and the second side of the embedded waterstop, thus forming the concrete section.
[0009] By adopting the above technical solution, first and second fixing frames are set up to form recesses on both sides of the embedded waterstop. During concrete pouring, the fixing frames and waterstop are wrapped around the waterstop, ensuring accurate and secure positioning. This fixing method prevents the waterstop from shifting or deforming during concrete pouring, ensuring a tight fit between the waterstop and the concrete, thereby enhancing the sealing of the expansion joint, reducing the risk of leakage, and improving the overall waterproofing effect.
[0010] Optionally, the actual distance from the first side of the embedded waterstop to the bottom surface of the first recess can be obtained; Based on the actual distance, determine the deviation point on the embedded waterstop and the corresponding deviation distance. Adjust the position of the embedded waterstop according to the deviation point and the deviation distance.
[0011] By adopting the above technical solution, the actual distance between the embedded waterstop and the bottom surface of the recess is obtained, the deviation point and deviation distance are determined, and the position of the waterstop is adjusted to ensure the installation accuracy of the waterstop. This adjustment avoids incomplete sealing caused by installation deviation, ensures that the waterstop is evenly stressed, and makes full contact with the expansion joint, effectively preventing water leakage from the gap between the waterstop and the concrete, and improving the reliability and durability of the waterproofing treatment.
[0012] Optionally, spatial clustering is performed on the deviation points to obtain deviation clusters; For the target deviation cluster in the deviation cluster, the deviation points in the target deviation cluster are counted to obtain deviation strips; An adjustment position is determined on the deviation strip, and the adjustment position is evenly distributed on the deviation strip; The adjustment distance is obtained based on the adjustment position and the deviation distance; Adjust the position of the embedded waterstop according to the adjustment position and the adjustment distance.
[0013] By employing the above technical solution, spatial clustering is performed on the deviation points to obtain deviation clusters, deviation strips are identified, and their positions are evenly distributed and adjusted on these clusters. The position of the waterstop is then adjusted according to the adjustment distance. This method systematically corrects the installation deviation of the waterstop, ensuring that the waterstop seals evenly along the expansion joint, eliminating local weak points, thereby significantly reducing the possibility of leakage and enhancing the integrity and stability of the waterproofing system.
[0014] Optionally, the slope at each point on the deviation strip is calculated to form a slope set; Detect whether a target slope exists in the slope set, wherein the target slope is greater than a preset slope threshold; If so, the difference between the target slope and the preset slope threshold is calculated to obtain the slope difference. An updated distance is generated based on the slope difference and the preset distance; Determine the target deviation strip corresponding to the target slope; The adjustment position is determined on the target deviation strip according to the update distance; If not, then determine the adjustment position on the deviation strip according to the preset distance.
[0015] By employing the above technical solution, the slope of the deviation strip is calculated, the target slope is detected and compared with a threshold, and an updated distance is generated to adjust the position, adapting to the shape changes of the expansion joint. This dynamic adjustment ensures that the waterstop fits tightly at the slope change point, preventing the waterproof layer from failing due to irregular shape, improving the adaptability and reliability of the waterproofing treatment, and ensuring effective waterproofing under various working conditions.
[0016] Optionally, the shape characteristics of the deviation strip are obtained; If the shape features conform to the preset shape, the inflection point position is determined on the deviation strip based on the shape features; Determine whether the distance between adjacent inflection points is greater than a preset distance based on the inflection point position; If so, then the inflection point position is set as the adjusted position; If not, then count the target inflection points whose adjacent distance is less than the preset distance; Combining the target inflection points yields an inflection point combination; The center position of the inflection point combination is taken as the adjustment position.
[0017] By employing the above technical solution, the shape characteristics of the deviation strip are obtained. When conforming to the preset shape, the inflection point position is determined, and the position is optimized and adjusted based on the inflection point distance to ensure accurate installation of the waterstop at key points. This method allows for fine-tuning of the complex shape of the expansion joint, ensuring full contact between the waterstop and the joint wall, preventing water leakage from the inflection point, and improving the accuracy and effectiveness of the waterproofing treatment.
[0018] Optionally, obtain the current construction parameters of the concrete section; Obtain historical construction parameters from historical processing records; Calculate the difference between the current construction parameters and the historical construction parameters to obtain the parameter difference; If the parameter difference is greater than the preset parameter difference threshold, the current construction parameters are adjusted according to the historical construction parameters.
[0019] By adopting the above technical solution, the current construction parameters of the concrete section are obtained, compared with historical construction parameters, the parameter differences are calculated and adjusted to ensure consistent concrete pouring quality. This parameter control avoids concrete defects caused by construction fluctuations, ensures the bonding strength between the concrete section and the waterstop, thereby reducing seepage channels and improving the overall waterproof performance and long-term stability of the tunnel expansion joint.
[0020] Secondly, this application provides a waterproofing system for tunnel expansion joints, employing the following technical solution: A waterproofing system for tunnel expansion joints, comprising: The acquisition module is used to acquire the input parameters of the waterproofing treatment method for the tunnel expansion joint; A memory for storing the program for the waterproofing treatment method of the tunnel expansion joint; The processor and the program in the memory can be loaded and executed by the processor to implement the waterproofing treatment method for the tunnel expansion joint.
[0021] By adopting the above technical solutions, the expansion joint is effectively sealed by pouring concrete and installing an embedded waterstop. Supporting materials are used to fill the expansion joint to prevent it from widening. A water collection box is embedded in the expansion joint and sealed in place to collect and drain seepage water, preventing water accumulation. The backwater side is sealed to prevent water leakage from the inside. A waterproof isolation layer is installed on the water-facing side to directly block external water pressure. A protective layer protects the waterproof layer from damage, thereby comprehensively improving the waterproof performance of the tunnel expansion joint and ensuring its long-term waterproof reliability.
[0022] Thirdly, this application provides a smart terminal, which adopts the following technical solution: A smart terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute the method described in any of the above-mentioned embodiments.
[0023] Fourthly, this application provides a computer storage medium capable of storing corresponding programs, which facilitates the improvement of waterproofing of tunnel expansion joints, and adopts the following technical solution: A computer-readable storage medium storing a computer program that can be loaded by a processor and executed any of the above-described methods for waterproofing tunnel expansion joints.

By setting up first and second fixing frames, recesses are formed to fix both sides of the embedded waterstop. When pouring concrete, the fixing frames and waterstop are wrapped to ensure the waterstop is accurately and firmly positioned.

[0035] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1 To be continued Figure 10 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.
[0036] This application discloses a method for waterproofing tunnel expansion joints. (Refer to...) Figure 1 The method includes: Step S101: Pour concrete to form a concrete section. The concrete section adopts an embedded waterstop. The concrete section consists of a first concrete section and a second concrete section. An expansion joint is provided between the first concrete section and the second concrete section.
[0037] Embedded waterstops are rubber, plastic, or metal strip-shaped waterproof materials installed inside concrete structures.
[0038] For example, please refer to Figure 2 The concrete section 21 includes a first concrete section 211 and a second concrete section 212. An expansion joint is provided between the first concrete section 211 and the second concrete section 212. An embedded waterstop 22 is also provided in the concrete section.
[0039] In some embodiments, this step includes steps S1011 to S1016, as detailed below: Step 1011: Set a first fixing frame, the first fixing frame having a first recess.
[0040] The first fixing frame is associated with the first concrete section. When forming the first concrete section, the first fixing frame can restrict the position of the embedded waterstop.
[0041] For example, please refer to Figure 3 Set the first fixing frame 31.
[0042] Step 1012: Place the first side of the embedded waterstop in the first recess.
[0043] The first side of the embedded waterstop is any side of the embedded waterstop.
[0044] For example, please refer to Figure 3 The first side of the embedded waterstop 22 is placed in the first recess.
[0045] Step 1013: Pour the first concrete section to form the first concrete section, so that the first concrete section covers the first fixing frame and the first side of the embedded waterstop.
[0046] For example, please refer to Figure 3 The first concrete section 211 was formed by pouring concrete.
[0047] Step 1014: Set a second fixing frame, the second fixing frame having a second recess.
[0048] The second fixing frame is related to the second concrete section. When forming the second concrete section, the second fixing frame can restrict the position of the embedded waterstop.
[0049] For example, please refer to Figure 3 Set a second fixing bracket 32.
[0050] Step 1015: Place the second side of the embedded waterstop in the second recess.
[0051] The second side of the embedded waterstop is the side of the embedded waterstop opposite to the first side mentioned above.
[0052] For example, please refer to Figure 3 The second side of the embedded waterstop 22 is placed in the second recess.
[0053] Step 1016: Pour the second concrete section to form the second concrete section, so that the second concrete section covers the second fixing frame and the second side of the embedded waterstop, forming the concrete section.
[0054] For example, please refer to Figure 3The second concrete section 212 is formed by pouring concrete.
[0055] Step S102: Fill the expansion joint with supporting material.
[0056] Optionally, when the expansion joint is located in the top slab, top slab, or side wall, the supporting material can be polyethylene foam joint filler board.
[0057] For example, please refer to Figure 3 Use support material 23 to fill the expansion joint.
[0058] Step S103: Install a water collection box on the surface of the expansion joint. The water collection box is embedded in the expansion joint, and the edge of the water collection box is sealed and fixed to the concrete part.
[0059] The water collection box is used to collect water and prevent it from entering the expansion joint. Optionally, the water collection box can be made of stainless steel.
[0060] For example, please refer to Figure 3 A water collection box 24 is installed on the surface of the expansion joint.
[0061] Step S104: Seal the backwater side of the expansion joint.
[0062] Optionally, when the expansion joint is located in the top slab or side wall, a two-component polyurethane sealant may be used for sealing, with a sealant depth of up to 4 cm. When the expansion joint is located in the bottom slab, a C30 precast concrete slab may be used for sealing, with the slab dimensions being 50cm*30cm*5cm.
[0063] For example, please refer to Figure 3 The backwater surface of the expansion joint is sealed to form a sealing layer 25.
[0064] Step S105: Install a waterproof isolation layer on the water-facing side of the expansion joint.
[0065] A waterproof isolation layer is used to protect expansion joints and prevent water from entering and damaging them. Furthermore, the waterproof isolation layer is placed between the waterproof layer and the external protective layer of the structure.
[0066] For example, please refer to Figure 3 A waterproof isolation layer 26 is installed on the water-facing side of the expansion joint.
[0067] Step S106: Apply a protective layer to the waterproof isolation layer.
[0068] Optionally, the protective layer may be a metal cover. For example, a stainless steel cover or an aluminum alloy cover may be used.
[0069] For example, please refer to Figure 3 A protective layer 27 is provided on the waterproof isolation layer 26.
[0070] By adopting the above technical solutions, the expansion joint is effectively sealed by pouring concrete and installing an embedded waterstop. Supporting materials are used to fill the expansion joint to prevent it from widening. A water collection box is embedded in the expansion joint and sealed in place to collect and drain seepage water, preventing water accumulation. The backwater side is sealed to prevent water leakage from the inside. A waterproof isolation layer is installed on the water-facing side to directly block external water pressure. A protective layer protects the waterproof layer from damage, thereby comprehensively improving the waterproof performance of the tunnel expansion joint and ensuring its long-term waterproof reliability.
[0071] In the following embodiments, due to the long length of the tunnel, the embedded waterstop is prone to distortion during installation, affecting its effectiveness. Therefore, this application discloses a method for adjusting the position of the embedded waterstop. (Refer to...) Figure 5 The method includes: Step S501: Obtain the actual distance from the first side of the embedded waterstop to the bottom surface of the first recess.
[0072] The actual distance is the distance from the first end of the embedded waterstop to the bottom surface of the first recess.
[0073] Step S502: Based on the actual distance, determine the deviation point on the embedded waterstop and determine the corresponding deviation distance.
[0074] Deviation point refers to the location on the embedded waterstop where the actual distance exceeds the preset standard design distance. When installing the embedded waterstop, it is crucial to ensure its accurate installation position. If its position deviates, the embedded waterstop may lose its waterproofing function. Therefore, this step requires adjusting the embedded waterstop based on its actual distance to move the deviation point back to meet the standard design distance.
[0075] Step S503: Adjust the position of the embedded waterstop according to the deviation point and deviation distance.
[0076] For example, a deviation point is determined on the embedded waterstop, and a portion of the embedded waterstop at the deviation point is moved according to the deviation distance.
[0077] By adopting the above technical solution, the actual distance between the embedded waterstop and the bottom surface of the recess is obtained, the deviation point and deviation distance are determined, and the position of the waterstop is adjusted to ensure the installation accuracy of the waterstop. This adjustment avoids incomplete sealing caused by installation deviation, ensures that the waterstop is evenly stressed, and makes full contact with the expansion joint, effectively preventing water leakage from the gap between the waterstop and the concrete, and improving the reliability and durability of the waterproofing treatment.
[0078] In practical scenarios, there are usually multiple deviation points on the embedded waterstop, forming continuous strips, requiring adjustment of these deviation points. Therefore, this application discloses a second method for adjusting the position of an embedded waterstop. (Refer to...) Figure 6 The method includes: Step S601: Perform spatial clustering on the off-center locations to obtain off-center clusters.
[0079] Off-center clusters are clusters formed by clustering at off-center locations.
[0080] Optionally, spatial clustering can be performed using any one of the following computational methods: DBSCAN, HDBSCAN, or K-Means.
[0081] Step S602: For the target deviation cluster in the deviation cluster, count the deviation points in the target deviation cluster to obtain the deviation strip.
[0082] The target deviation cluster is any one of the deviation clusters. The deviation band is a band composed of the deviation points in the target deviation cluster.
[0083] For example, on the embedded waterstop strip, the deviation points in the target deviation cluster are identified. It is then determined whether the distance between adjacent deviation points is less than the classification clustering threshold. If so, the adjacent deviation points are classified into the same deviation strip. If not, the adjacent deviation points are classified into different deviation strips.
[0084] Step S603: Determine the adjustment positions on the deviation strip, and the adjustment positions are evenly distributed on the deviation strip.
[0085] Adjustment position refers to the position where adjustments are made off the strip. For example, adjusting the position of an embedded waterstop at the adjustment position.
[0086] The determination of the adjusted position can be found in the following sections. Figure 7 The embodiments shown are not described in detail here.
[0087] Step S604: Obtain the adjustment distance based on the adjustment position and the deviation distance.
[0088] For example, the adjustment position is determined on the embedded waterstop. The deviation distance corresponding to the adjustment position is determined to obtain the adjustment distance.
[0089] Step S605: Adjust the position of the embedded waterstop according to the adjustment position and adjustment distance.
[0090] For example, the adjustment position on the embedded waterstop is moved according to the adjustment position.
[0091] By employing the above technical solution, spatial clustering is performed on the deviation points to obtain deviation clusters, deviation strips are identified, and their positions are evenly distributed and adjusted on these clusters. The position of the waterstop is then adjusted according to the adjustment distance. This method systematically corrects the installation deviation of the waterstop, ensuring that the waterstop seals evenly along the expansion joint, eliminating local weak points, thereby significantly reducing the possibility of leakage and enhancing the integrity and stability of the waterproofing system.
[0092] This application discloses a method for determining the adjustment position. (Refer to...) Figure 7 The method includes: Step S701: Calculate the slope at each point on the deviation strip to form a slope set.
[0093] The slope here refers to the degree of inclination or rate of change of the deviation strip in space. In this step, by calculating the slope at various points and forming a set, the shape deviation of the waterstop is transformed into analyzable data, providing a data basis for subsequent determination of which areas require key adjustments.
[0094] The slope set includes the mapping relationship between position and slope.
[0095] Step S702: Detect whether there is a target slope in the slope set, and the target slope is greater than the preset slope threshold.
[0096] The preset slope threshold is a pre-defined empirical value, which technicians can adjust according to actual needs. It is used to define the critical point at which the shape of the waterstop changes "drastically" or "significantly". When the slope at a certain location exceeds the aforementioned preset slope threshold, it means that the waterstop may have made a sharp turn or abrupt change, which is a potential weak point in the waterproofing.
[0097] Step S703: If yes, calculate the difference between the target slope and the preset slope threshold to obtain the slope difference.
[0098] The slope difference is the difference between the target slope and the preset slope threshold.
[0099] Step S704: Generate an updated distance based on the slope difference and the preset distance.
[0100] In areas with large slope differences, more frequent or larger adjustment points are needed to ensure proper fit of the waterstop. The update distance is usually smaller than the preset distance, resulting in more frequent adjustment points where the target deviates from the strip, achieving finer correction.
[0101] Step S705: Determine the target deviation strip corresponding to the target slope.
[0102] The target deviation band refers to the deviation band with the target slope.
[0103] Step S706: Determine the adjustment position on the target deviation strip according to the updated distance.
[0104] For example, the adjustment position is determined on the target deviation strip at intervals of updated distance.
[0105] Step S707: If not, determine the adjustment position on the deviation strip according to the preset distance.
[0106] In areas with small slope differences, the overall shape of the embedded waterstop is gentle and the slope does not exceed the threshold. The position is then adjusted according to the conventional and uniform preset distance, which ensures the efficiency and quality of foundation construction.
[0107] By employing the above technical solution, the slope of the deviation strip is calculated, the target slope is detected and compared with a threshold, and an updated distance is generated to adjust the position, adapting to the shape changes of the expansion joint. This dynamic adjustment ensures that the waterstop fits tightly at the slope change point, preventing the waterproof layer from failing due to irregular shape, improving the adaptability and reliability of the waterproofing treatment, and ensuring effective waterproofing under various working conditions.
[0108] This application discloses a second method for determining the adjustment position. (Refer to...) Figure 8 The method includes: Step S801: Obtain the shape features of the deviation from the strip.
[0109] Shape features are used to describe the overall spatial morphology of the deviation from the strip. Optionally, shape features include, but are not limited to, whether its outline is wavy, serrated, or has multiple obvious directional turns.
[0110] In some embodiments, construction images of the embedded waterstop are acquired. Deviation strips are identified from the construction images to obtain deviation strip images. Shape features are then obtained from the deviation strip images.
[0111] Step S802: If the shape features conform to the preset shape, determine the inflection point position on the deviation strip according to the shape features.
[0112] Preset shapes refer to predefined shape types that require special processing. For example, the Yisuhe River has a continuous S-shape. When the current shape is identified as conforming to this preset shape, the system will automatically locate the "inflection points" where significant changes occur in all directions. These inflection points are usually crucial for ensuring a good seal.
[0113] Step S803: Determine whether the distance between adjacent inflection points is greater than the preset distance based on the inflection point position.
[0114] The preset distance is a pre-set empirical value, and technicians can adjust the preset distance value according to actual needs.
[0115] Step S804: If yes, then set the inflection point position to the adjustment position.
[0116] If the distance between two inflection points is large enough, it indicates that they are each independent critical locations. In this case, directly using the inflection points as adjustment positions can most effectively correct deviations in these critical points and ensure that the waterstop fits tightly at these locations.
[0117] Step S805: If not, count the target inflection points whose adjacent distance is less than the preset distance.
[0118] When the distance between adjacent inflection points is no greater than the preset distance, these target inflection points are too close to each other. If each one is adjusted individually, it will not only be inefficient, but may also affect the performance of the waterstop due to excessive operation.
[0119] Step S806: Combine the target inflection points to obtain the inflection point combination.
[0120] By treating a dense cluster of inflection points as a single problem region requiring holistic processing, we obtain a combination of inflection points. By combining these combinations, the processing of multiple discrete points can be integrated into the processing of a single region.
[0121] Step S807: Use the center position of the inflection point combination as the adjustment position.
[0122] By employing the above technical solution, the shape characteristics of the deviation strip are obtained. When conforming to the preset shape, the inflection point position is determined, and the position is optimized and adjusted based on the inflection point distance to ensure accurate installation of the waterstop at key points. This method allows for fine-tuning of the complex shape of the expansion joint, ensuring full contact between the waterstop and the joint wall, preventing water leakage from the inflection point, and improving the accuracy and effectiveness of the waterproofing treatment.
[0123] This application discloses a parameter adjustment method. (Refer to...) Figure 9 The method includes: Step S901: Obtain the current construction parameters of the concrete section.
[0124] Current construction parameters refer to the construction parameters of the concrete section at the current moment of construction. Optional construction parameters include at least one of the following: slump, water-cement ratio, aggregate parameters, cementitious material dosage, cementitious material ratio, vibration parameters, curing temperature, and curing humidity.
[0125] Step S902: Obtain historical construction parameters from historical processing records.
[0126] Historical construction parameters are the construction parameters of the concrete section at historical construction times.
[0127] Step S903: Calculate the difference between the current construction parameters and the historical construction parameters to obtain the parameter difference.
[0128] In some embodiments, if the construction parameters include multiple parameters, the current construction parameters are normalized to obtain normalized current parameters. The normalized current parameters are then weighted to obtain weighted current construction parameters. Historical construction parameters are normalized to obtain normalized historical parameters. The normalized historical parameters are then weighted to obtain weighted historical construction parameters.
[0129] Step S904: If the parameter difference is greater than the preset parameter difference threshold, the current construction parameters are adjusted according to the historical construction parameters.
[0130] The preset parameter difference threshold is a preset empirical value. Technicians can adjust the specific value of the preset parameter difference threshold according to actual needs.
[0131] By adopting the above technical solution, the current construction parameters of the concrete section are obtained, compared with historical construction parameters, the parameter differences are calculated and adjusted to ensure consistent concrete pouring quality. This parameter control avoids concrete defects caused by construction fluctuations, ensures the bonding strength between the concrete section and the waterstop, thereby reducing seepage channels and improving the overall waterproof performance and long-term stability of the tunnel expansion joint.
[0132] Based on the same inventive concept, embodiments of this application provide a waterproofing system for tunnel expansion joints. Please refer to... Figure 10 ,include: The acquisition module 1001 is used to acquire the input parameters of the waterproofing treatment method for the tunnel expansion joint; The memory 1002 is used to store the program for the waterproofing treatment method of the tunnel expansion joint; The processor 1003 can load and execute programs in memory to implement the waterproofing method for tunnel expansion joints.
[0133] By adopting the above technical solutions, the expansion joint is effectively sealed by pouring concrete and installing an embedded waterstop. Supporting materials are used to fill the expansion joint to prevent it from widening. A water collection box is embedded in the expansion joint and sealed in place to collect and drain seepage water, preventing water accumulation. The backwater side is sealed to prevent water leakage from the inside. A waterproof isolation layer is installed on the water-facing side to directly block external water pressure.
