Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering seepage prevention technology, specifically a composite seepage prevention connection structure for dike-penetrating structures, used to solve the seepage damage problem caused by uneven settlement and leakage between dike-penetrating structures and dikes, and to achieve seepage prevention and sealing between dike-penetrating structures and dikes on both sides. Background Technology

[0002] Structures that pass through dikes refer to various structures that pass through dikes, mainly including sluice gates, pumping stations, gate stations, culverts, and culvert gates, which meet the functional requirements of flood control, drainage, irrigation, and water supply.

[0003] Currently, the seepage prevention system for embankment projects on soft soil foundations generally adopts a cohesive soil structure with layer-by-layer compaction. However, as a linear project, the standard for settlement control is relatively low. As point-type projects, the embankment penetration structures have higher requirements for settlement control and generally adopt foundation reinforcement treatment. This makes the joint between the soil embankment body and the penetration structures extremely prone to seepage damage due to uneven settlement, leakage at the contact surface, or improper structural connection, threatening the safety of the embankment and becoming a weak link in the seepage prevention of the embankment project.

[0004] Due to the narrow working area of ​​the connection section between the structures crossing the dike, heavy compaction equipment could not be used in many areas. Furthermore, small-scale and intelligent construction equipment was not selected at the construction site. Insufficient control over the layered filling construction and the quality of the backfill soil resulted in a generally low degree of compaction of the backfill soil at the connection section between the structures crossing the dike and the dike. This further aggravated the leakage problem at the connection section between the soil dike body and the structures crossing the dike.

[0005] In summary, there is an urgent need for a new type of seepage-proof structure that combines the advantages of reliable seepage prevention, implementability, and economy, in order to systematically solve the foundation leakage problem at the connection section between the structure penetrating the dike and the dike, and ensure the overall safety of the project. Utility Model Content

[0006] This utility model aims to provide a composite seepage-proof connection structure for dike-penetrating structures, which solves the problem of seepage damage at the connection section between the dike-penetrating structure and the dike, achieves reliable seepage-proof connection, and ensures controllable construction quality and intelligent operation and maintenance.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0008] This utility model discloses a composite seepage-proof connection structure for a dike-penetrating structure, including a dike and a partially located dike-penetrating structure within the dike. Concrete spiked walls are provided on both sides of the dike-penetrating structure to form a vertical seepage-proof structure. High-pressure jet grouting seepage-proof walls are provided inside the dike on both sides of the dike-penetrating structure to form a vertical seepage-proof structure for the dike. The high-pressure jet grouting seepage-proof walls are connected to the concrete spiked walls, and the connection point forms a connecting section.

[0009] Preferably, the connecting section of the dike-crossing structure is provided with multiple backfill layers, and the backfill layers form a stepped structure.

[0010] Preferably, the backfill layer of the connecting section of the dike-crossing structure is a conventional cohesive soil layer or a new type of engineering material layer; the new type of engineering material layer includes a cement-modified soil layer and a foamed lightweight soil layer.

[0011] Preferably, a fluidized solidified soil layer is provided in the narrow area of ​​the embankment structure.

[0012] Preferably, the structure through the dike is provided with a vertical seepage barrier layer, and the vertical seepage barrier layer, the concrete piercing wall, and the high-pressure jet grouting seepage barrier wall together constitute the overall seepage prevention system of the connecting section.

[0013] Preferably, the backfill layer of the connecting section of the dike-crossing structure is equipped with a layered settlement observation device and a surface settlement observation device, and the layered settlement observation device and the surface settlement observation device are communicatively connected to a controller with a display function.

[0014] Preferably, intelligent seepage monitoring equipment is installed before and after the high-pressure jet grouting anti-seepage wall at the connection section, and the layered settlement observation equipment, surface settlement observation equipment and seepage monitoring equipment form a monitoring system.

[0015] Beneficial Effects: Safe and Reliable Seepage Prevention Connection: Through the synergistic effect of concrete piercing walls, high-pressure jet grouting seepage prevention walls, and the vertical seepage prevention layer of the structure, combined with a reasonable backfilling construction and monitoring system, seepage damage caused by uneven settlement and leakage is solved, ensuring a reliable seepage prevention connection between the structure penetrating the dike and the dike. Controllable Construction Quality: With the help of stepped backfilling and an intelligent construction monitoring system, backfilling construction is transformed from "experience-based construction" to "digital management," ensuring the construction quality of the connection section and making it a reliable seepage prevention barrier for the dike project, improving the seepage prevention safety throughout the entire life cycle of the project. Intelligent Operation and Maintenance: Relying on the settlement and monitoring system, an intelligent operation and maintenance management platform is established, realizing the transformation from "passive emergency response" to "proactive prevention and control," providing a technical approach for forming a closed-loop management system of "monitoring → early warning → disposal → assessment," ensuring the long-term safe operation of the structure penetrating the dike.

[0021] Technical solution / principle of this utility model:

[0022] This utility model discloses a composite seepage-proof connection structure for a transect structure, comprising a dike 2 and a transect structure 1 partially located within the dike 2. The transect structure 1 mainly includes structures such as sluice gates, pumping stations, gate stations, culverts, and culvert gates. The dike 2 is primarily a homogeneous earth dike, and its main seepage-proof system is a cohesive soil structure constructed by layer-by-layer compaction. Concrete spiked walls 3 are provided on both sides of the transect structure 1 to form a vertical seepage-proof structure. High-pressure jet grouting seepage-proof walls 4 are provided within the dike 2 on both sides of the transect structure 1 to form a vertical seepage-proof structure for the dike 2. The high-pressure jet grouting seepage-proof walls 4 are connected to the concrete spiked walls 3, and the connection point constitutes a connection section. A vertical seepage-proof layer 5 is provided within the transect structure 1. The vertical seepage-proof layer 5, the concrete spiked walls 3, and the high-pressure jet grouting seepage-proof walls 4 together constitute the overall seepage-proof system of the connection section.

[0023] Backfill Construction and Materials: Multiple backfill layers 6 are installed at the connection section of the dike-penetrating structure 1, forming a stepped structure. The backfill layers 6 at the connection section of the dike-penetrating structure 1 are either conventional cohesive soil layers or new engineering material layers; the new engineering material layers include cement-modified soil layers and foamed lightweight soil layers. A fluidized solidified soil layer is installed in the narrow areas of the dike-penetrating structure 1 to solve the problem of "inadequate compaction and tamping" in narrow areas, ensuring the continuity of the overall seepage prevention system of the dike.

[0024] Monitoring System: Layered settlement monitoring devices 72a and surface settlement monitoring devices 72b are embedded in the backfill layer 6 of the connecting section of the dike structure 1. The layered settlement monitoring devices 72a and surface settlement monitoring devices 72b are communicatively connected to a controller with display function (such as a PLC controller with a touch screen display, which can display settlement data in real time). Intelligent seepage monitoring devices 71, such as electromagnetic seepage monitoring sensors, are deployed before and after the high-pressure jet grouting anti-seepage wall 4 at the connecting section. These devices can accurately capture seepage data. The layered settlement monitoring devices 72a, surface settlement monitoring devices 72b, and seepage monitoring devices 71 together form a monitoring system.

[0025] For the backfilling construction of the connecting section of the embankment structure 1, an intelligent construction monitoring system can be used. This system can utilize real-time compaction monitoring (e.g., using wirelessly transmitted compaction sensors) and 3D positioning guidance technology (based on GPS or BIM 3D models) to establish a digital construction archive and enable real-time, full-process control of the backfilling construction. Based on the design scheme of this application, the quality acceptance standards for the backfilling construction of the connecting section of the embankment structure 1 can be optimized and adjusted, adding new quality control indicators such as the contact surface permeability coefficient and differential settlement index. Non-destructive testing technologies can be used, such as using a surface wave meter to detect the density of the bonding surface (judging by the difference in the propagation speed of surface waves in soils of different densities), infrared thermal imaging to identify void areas (based on the temperature difference between void and dense areas), and acoustic CT scanning to construct a 3D density model (modeling based on the attenuation degree of sound waves penetrating soils of different densities).

[0026] Structural construction: such as Figure 1-3 As shown, the foundation of dike 2 is constructed first, and the section of the through-dike structure 1 (such as a culvert) is embedded into dike 2 according to the design. Concrete piercing walls 3 are constructed on both sides of the through-dike structure 1 as vertical seepage prevention structures, ensuring a tight fit between the concrete piercing walls 3 and the through-dike structure 1 and dike 2. Next, high-pressure jet grouting seepage prevention walls 4 are constructed inside dike 2 on both sides of the through-dike structure 1, interlocking with the concrete piercing walls 3 to form a connecting section. Simultaneously, a vertical seepage prevention layer 5 is constructed within the through-dike structure 1, forming an integrated seepage prevention system together with the concrete piercing walls 3 and the high-pressure jet grouting seepage prevention walls 4.

[0027] Construction of Backfill Layer 6: For the connection section of the embankment structure 1, a layered and meticulous construction method is adopted, and multiple backfill layers 6 are constructed according to the design, so that the backfill layers 6 form a stepped structure (similar to a ladder, with the width and height of each staggered layer determined according to the design). Conventional cohesive soil or new engineering materials (such as cement-modified soil or foamed lightweight soil) can be selected to fill backfill layers 6 according to the actual geological and seepage prevention requirements of the project. For narrow areas of the embankment structure 1 (such as areas with limited space or where mechanical compaction is difficult), fluidized solidified soil is used for filling, relying on its self-flowing characteristics to achieve dense filling without the need for strong mechanical compaction.

[0028] Monitoring equipment deployment: During the construction of backfill layer 6, layered settlement observation equipment 72a (which can be a device that combines layered settlement magnetic rings with measuring tapes, with magnetic rings arranged in layers along backfill layer 6) and surface settlement observation equipment 72b, such as settlement observation markers corresponding to high-precision levels, are simultaneously installed and connected to a controller with display function (such as the aforementioned combination of a PLC controller and a touch screen, with the controller installed in the on-site monitoring cabinet or remote monitoring room). Before and after the high-pressure jet grouting anti-seepage wall 4 in the connecting section, seepage monitoring equipment 71 is deployed at the designed interval, such as the selected electromagnetic seepage monitoring sensors. Waterproofing and anti-interference treatments are carried out to make the layered settlement observation equipment 72a, surface settlement observation equipment 72b, and seepage monitoring equipment 71 form a monitoring system. Data can be transmitted in real time to the intelligent operation and maintenance management platform (via wireless or wired network transmission; the operation and maintenance platform includes conventional controllers, displays, etc.).

[0029] Construction Management and Execution: An intelligent construction monitoring system can be activated. During backfilling, real-time compaction monitoring sensors (deployed on the roller or backfilling surface) transmit compaction data to the monitoring system in real time. Utilizing 3D positioning guidance technology (such as a BIM-based positioning system, allowing construction personnel to view real-time positioning deviations from the design position via mobile terminals), the system ensures that the backfill layer's position, thickness, and other parameters conform to the design. Simultaneously, the system automatically establishes digital construction archives, recording information such as construction time, location, compaction degree, and initial settlement data, achieving full-process control.

[0030] Quality Acceptance Procedures: After construction is completed, acceptance can be conducted according to the optimized quality acceptance standards. This includes testing the contact surface permeability coefficient (which can be tested on-site using the double-ring method) and differential settlement index (settlement data recorded by monitoring equipment). Non-destructive testing techniques are used to assist in acceptance, such as surface wave meter testing (setting test points along the surface of the joint section to collect surface wave data and analyze the density of the joint surface); infrared thermal imaging testing (scanning the joint section with an infrared thermal imager to identify areas of abnormal temperature and voids); and acoustic CT scanning (setting acoustic wave transmitting and receiving devices on both sides of the joint section to collect acoustic wave data and construct a three-dimensional density model to comprehensively determine whether the construction quality meets the standards).

[0031] During the construction and operation phases, the monitoring system monitors differential settlement and seepage in real time. If differential settlement exceeds the limit (e.g., exceeding the design allowable value by 5mm), grouting compensation is promptly implemented (using appropriate grouting materials, such as cement-water glass double-liquid grout, and precisely grouting through grouting pipes). If seepage is abnormal, the leakage point is located based on seepage monitoring data, and corresponding seepage prevention measures are taken (e.g., high-pressure jet grouting for pile repair, application of seepage prevention coatings, etc.) to achieve long-term, reliable seepage prevention connection and safe operation between the structures penetrating the dike and the dike.

[0032] Finally, it should be noted that this utility model is not limited to the above embodiments, and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
