Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and water transport engineering technology, and more specifically, relates to a combined lining structure of a lock chamber floor wall. Background Technology

[0002] In shipping engineering, locks are among the most widely used navigation structures. Their main components consist of upper and lower lock heads, lock chambers, and upstream and downstream approach channels. When a ship travels upstream, the water level in the lock chamber must first be lowered to the downstream level, the lower lock gate is opened, the ship enters the lock chamber, the lower lock gate is closed, water is then pumped into the lock chamber from upstream to the upstream level, and finally the upper lock gate is opened, allowing the ship to leave the lock chamber and enter the upstream channel. The process for ships traveling downstream is the reverse.

[0003] Lock chamber structures are typically vertical, consisting of sidewalls and a bottom slab. They can be broadly classified into two categories based on their construction: integral structures and separate structures. Integral structures have sidewalls cast together with the bottom slab, while separate structures have sidewalls and bottom slabs installed separately. In current engineering technology, commonly used integral lock structures include integral dock structures and hollow box structures. These structures have thick bottom slabs and high overall rigidity, but for integral structures with high walls and wide bottom slabs, the workload is substantial, and significant uneven settlement may occur. Separate structures have various sidewall types, mainly including sheet pile, gravity, cantilever, and hybrid types, and their bottom slabs mostly use permeable slabs. The selection of the lock chamber structure type requires comprehensive analysis and determination of factors such as geological and soil conditions, upstream and downstream water heads, and construction conditions. In the lock chamber structure, the lining structure is an important component. However, the commonly used lining structure has obvious shortcomings. It adopts the method of rebar installation without steel plate protection. Not only is the rebar installation not firm, the construction is cumbersome and the quality is difficult to control, but the rebar connection performance is also poor and the strength is insufficient. In the main project of the lock, under the load of repeated water level changes, water flow, ship impact, ship mooring force and other loads, it is very easy to be damaged and cracked, and repair is difficult. Utility Model Content

[0004] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a combined lining structure for the diaphragm wall of a lock chamber. This structure involves sequentially installing a concrete lining and a steel lining on the inner side of the diaphragm wall. One end of a pre-embedded connector is embedded in the diaphragm wall, while the other end extends into the concrete lining. An anchor welded to the inner side of the steel lining extends into the concrete lining at the other end. This creates an integral structure with the steel lining, concrete lining, connector, anchor, and diaphragm wall, possessing extremely high safety, stability, and rigidity, capable of withstanding various loads and external impacts during lock operation. Simultaneously, the steel lining, as a crucial structural component, serves as the lock chamber's protective surface, resisting ship impacts with its excellent impact resistance and wear resistance, protecting the lock chamber wall, and extending the lock chamber's service life. Monitoring components are fixedly installed on the connectors, connected to a data acquisition device (MCU) via cables. The monitoring system, consisting of steel bars embedded in the connectors, connecting cables, and the MCU, can monitor the lining structure, tracking stress changes and operational status in real time. This provides precise technical parameters for subsequent operation and management, facilitating timely understanding of the structural condition and enabling scientific maintenance and management by staff.

[0005] To achieve the above objectives, this utility model proposes a combined lining structure for the diaphragm wall of a lock chamber, comprising a diaphragm wall, a steel lining, a concrete lining, connectors, and anchoring components; wherein, The diaphragm wall is provided with a concrete lining on its inner side, and a steel lining is provided on its inner side. A connector is embedded in the diaphragm wall, with one end embedded in the diaphragm wall and the other end extending into the concrete lining, which tightly connects the diaphragm wall and the concrete lining together, effectively transferring the stress between the two and enhancing the overall structure. Anchoring elements are welded to the inner side of the steel lining, and the other end of the anchoring elements extends into the concrete lining, which enhances the connection between the steel lining and the concrete lining. This makes the steel lining, concrete lining, connectors and anchoring elements form an integral structure with the diaphragm wall, thereby giving the lining structure high safety, stability and rigidity to cope with various loads and external impacts that may be encountered during the operation of the lock.

[0006] Furthermore, a monitoring component is fixedly installed on the connector. Each monitoring component is fixedly installed on the non-bending section of the connector. The monitoring component is connected to the data acquisition device MCU via a cable, and the data acquisition device MCU reads the data. All the rebar gauges, connecting cables, and data acquisition devices MCU embedded in the connector together constitute the monitoring system.

[0007] Furthermore, the connector is made of steel bars with a diameter of 12-16mm. The connector is in the shape of an "U" with two extended sides. The length of its bent section is not less than 600mm. The bent section is wrapped with a plastic sleeve and filled with polystyrene board on the outside. During the construction of the diaphragm wall, the connector is tied to the steel cage of the diaphragm wall and lowered into the diaphragm wall trench along with the steel cage. During the construction of the concrete lining, the surface of the diaphragm wall is first roughened, and then the bent section of the connector is bent at a certain angle and the plastic sleeve on the bent section is removed so that the bent steel end can be connected to the steel bars on the inner and outer sides of the concrete lining.

[0008] Furthermore, the steel lining is made of Q235B steel plate with a thickness of 10mm. The steel lining is made in sections along the vertical direction, and the length of each section is determined according to the layer height of the concrete pouring, so that it can better adapt to the construction process. The joints between the sections are connected by continuous welds, which ensures the sealing and firmness of the connection between the sections of the steel lining.

[0009] Furthermore, the anchoring element is made of steel bar with a diameter of 12mm. One end of the anchoring element is connected to the steel lining by double-sided welding. The weld length is not less than 5 times the diameter of the steel bar in the anchoring element. The other end of the anchoring element is lapped with the steel reinforcement skeleton in the concrete lining. The vertical spacing of the anchoring elements is 400mm.

[0010] Furthermore, the concrete lining is made of C30 concrete and has internal steel bars with a diameter of 20mm or 22mm. The thickness of the concrete lining is usually 300mm, and the joint length in the horizontal direction is set to 15-20m. During construction, the concrete lining is poured vertically in layers, with each layer being 6m high.

[0011] Furthermore, the surfaces of the steel liner and anchoring components need to be polished and derusted to thoroughly remove rust, oil, and impurities, ensuring that the subsequent coating can adhere firmly. The side of the anchoring component embedded in the concrete liner should be coated with a water-based inorganic zinc-rich coating. The exposed water-facing surface of the steel liner should be coated with two coats of red lead vinyl anti-rust paint, each coat being 0.08 mm thick, for a total thickness of 0.16 mm. On top of the anti-rust paint, two coats of chlorinated rubber topcoat should be applied, each coat being 0.05 mm thick, for a total thickness of 0.10 mm.

[0012] Furthermore, the monitoring device is a rebar gauge, which is a vibrating wire instrument with specifications matching the diameter of the rebar. The measurement range is 0 to 400 MPa, with an accuracy of ±0.25%FS, a sensitivity of 0.016%FS, and an applicable temperature range of -20ºC to +80ºC.

[0013] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects: (1) The combined lining structure of the lock chamber diaphragm wall of this utility model has a concrete lining inside the diaphragm wall, a steel lining inside the concrete lining, and a connector pre-embedded in the diaphragm wall. One end of the connector is firmly embedded in the diaphragm wall, and the other end extends into the concrete lining, tightly connecting the diaphragm wall and the concrete lining together, effectively transferring the stress between the two and enhancing the overall structure. An anchor is welded inside the steel lining, and the other end of the anchor extends into the concrete lining. The steel lining, concrete lining, connector, and anchor together form a composite structure. The diaphragm wall forms an integral structure, giving the lining structure extremely high safety, stability, and rigidity. It can easily cope with various loads and external impacts that may be encountered during the operation of the lock. The steel lining is not only an important component of the structural system, but also bears the important responsibility of the lock chamber lining. Since ships inevitably collide with the lock chamber wall when passing through or docking in the lock chamber, the steel lining, with its excellent impact resistance and wear resistance, can effectively resist the impact of ships, protect the lock chamber wall from damage, and greatly extend the service life of the lock chamber.

[0014] (2) The combined lining structure of the lock chamber of this utility model is made by fixing monitoring components on the connectors. The monitoring components are connected to the data acquisition device MCU via cables. The data acquisition device MCU reads the data. All the steel bars, connecting cables and data acquisition device MCU embedded on the connectors together constitute the monitoring system. The monitoring system can complete the monitoring of the lining structure, track the stress changes and operating status of the structure in real time, and provide accurate and effective technical parameters for subsequent operation and management. This makes it easier for staff to grasp the structural condition in a timely manner and carry out scientific and reasonable maintenance and management. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Example 1 like Figure 1 As shown in the figure, this embodiment provides a lock chamber diaphragm wall combined lining structure, including a lock chamber 1, an upper lock head 2, and a lower lock head 3. The lock chamber 1 is located between the upper lock head 2 and the lower lock head 3, forming a key passage for ship passage. To ensure the structural stability on both sides of the lock chamber, diaphragm walls 11 are arranged on the left and right banks of the lock chamber 1, respectively. These diaphragm walls serve as the basic load-bearing part of the entire lining structure, providing solid and reliable support for the installation and coordinated work of subsequent layers of the structure.

[0019] like Figure 2-7As shown, the inner side of the diaphragm wall 11 is provided with a concrete lining 13, and the inner side of the concrete lining 13 is provided with a steel lining 12. This double-layer lining improves the overall structural performance. A connector 14 is pre-embedded in the diaphragm wall 11. One end of the connector is firmly embedded in the diaphragm wall 11, and the other end extends into the concrete lining 13, tightly connecting the diaphragm wall 11 and the concrete lining 13 together, effectively transferring the stress between the two and enhancing the overall integrity of the structure. At the same time, an anchor 15 is welded to the inner side of the steel lining 12. The other end of the anchor 15 extends into the concrete lining 13, further strengthening the connection between the steel lining 12 and the concrete lining 13. Through this connection method, the steel lining 12, the concrete lining 13, the connector 14, and the anchor 15 together form an inseparable integral structure with the diaphragm wall 11, giving the lining structure extremely high safety stability and strong rigidity, and enabling it to easily cope with various loads and external force impacts that may be encountered during the operation of the lock, such as water flow pressure and the squeezing force when ships are docked. The steel lining 12 is not only an important component of the structural system but also plays a crucial role in the lock chamber's facing. Since ships inevitably collide with the lock chamber walls when passing through or berthing, the steel lining, with its excellent impact resistance and wear resistance, effectively withstands these impacts, protecting the lock chamber walls from damage and significantly extending the lock chamber's service life. The concrete lining 13 acts as a transition and buffer in the structure. On the one hand, it evenly transfers the external forces borne by the steel lining to the diaphragm wall; on the other hand, it provides a good medium for the connection between the steel lining and the diaphragm wall, further enhancing the structure's integrity and stability. The diaphragm wall 11, as the foundation of the entire structure, provides stable support for the superstructure with its strong load-bearing capacity and deformation resistance, ensuring that the entire lining structure will not experience excessive settlement or deformation during long-term use. Furthermore, this composite lining structure also possesses good economic efficiency and practicality. The presence of steel lining reduces the need for additional protective treatment of the gate chamber wall surface, lowering later maintenance costs; while the integrated structural design reduces uncertainties in the construction process, improves construction efficiency, and shortens the construction period.

[0020] like Figure 3-5As shown, the connector 14 is made of steel bars with a diameter of 12-16mm. During the construction of the diaphragm wall 11, the connector 14 is in the shape of an "U" with extended sides. The length of its bent section is not less than 600mm, and the bent section is wrapped with a plastic sleeve and filled with polystyrene board on the outside. During the construction of the diaphragm wall 11, the connector 14 is tied to the steel cage of the diaphragm wall 11 and lowered into the diaphragm wall trench section together with the steel cage of the diaphragm wall 11. During the construction of the concrete lining 13, the surface of the diaphragm wall 11 is first roughened, and then the bent section of the connector 14 is bent at a certain angle, and the plastic sleeve on the bent section is removed so that the bent steel bar end can overlap with the steel bars on the inner and outer sides of the concrete lining 13, thereby realizing the effective connection between the connector 14 and the concrete lining 13, and further strengthening the integrity of the entire lining structure.

[0021] Furthermore, the steel liner 12 is made of 10mm thick Q235B steel plate. The steel liner 12 is manufactured in segments along the vertical direction, with the segment length determined by the layer height of the concrete pouring to better adapt to the construction process. The joints between the segments are connected by continuous welds, ensuring the sealing and robustness of the connections between the steel liner segments. To facilitate the installation and lifting of the steel liner, lifting lugs are welded to one side of the steel liner 12, and these lugs are embedded in the cast-in-place concrete. After the formwork is installed, small steel plates are welded together at the joints of the steel liner for positioning, ensuring the stability of the steel liner during concrete pouring. After the concrete pouring is completed, the joints are fully welded to further enhance the overall structural strength and sealing of the steel liner.

[0022] Furthermore, the anchoring element 15 is made of 12mm diameter steel bar, which plays a crucial role in the connection between the steel lining 12 and the concrete lining 13. One end of the anchoring element 15 is connected to the steel lining 12 by double-sided welding. To ensure welding strength, the weld length is no less than 5 times the diameter of the anchoring element steel bar. The other end overlaps with the steel reinforcement skeleton in the concrete lining 13, allowing the steel lining and concrete lining to be tightly bonded. At the same time, the vertical spacing of the anchoring elements 15 is 400mm, ensuring the stability of the connection and allowing stress to be evenly distributed, further enhancing the overall structural strength of the steel lining 12, concrete lining 13, and diaphragm wall 11.

[0023] Furthermore, to further enhance the durability and service life of the steel liner 12 and anchor 15, rigorous surface treatment and painting operations are required during construction. The surfaces of the steel liner 12 and anchor 15 must be polished and derusted to thoroughly remove rust, oil, and impurities, ensuring strong adhesion of subsequent coatings. Specifically, the side of the anchor 15 embedded in the concrete liner 13 should be coated with a water-based inorganic zinc-rich coating. This coating has excellent anti-corrosion properties, effectively isolating the anchor 15 from corrosive media and protecting it from corrosion. For the exposed water-facing surface of the steel liner 12, the painting process is even more refined. First, two coats of red lead vinyl anti-rust paint are applied, each coat being 0.08 mm thick, for a total thickness of 0.16 mm. This anti-rust paint forms a dense protective film, effectively blocking moisture, oxygen, and other substances from corroding the steel lining 12. On top of the anti-rust paint, two coats of chlorinated rubber topcoat are applied, each coat being 0.05 mm thick, for a total thickness of 0.10 mm. The chlorinated rubber topcoat not only has excellent weather resistance and water resistance but also provides the steel lining 12 with an aesthetically pleasing appearance, further enhancing its corrosion resistance and ensuring that the steel lining 12 maintains good performance in the long-term aquatic environment, better fulfilling its role as a lock chamber lining and protecting it from collisions with the lock chamber wall.

[0024] Furthermore, the concrete lining 13, serving as a crucial intermediate structure connecting the diaphragm wall 11 and the steel lining 12, is constructed using C30 concrete and provides reliable strength support for the entire lining structure. According to structural stress and construction requirements, the concrete lining 13 is internally reinforced with steel bars of 20mm or 22mm diameter to meet the load-bearing requirements of the structure under stress. The thickness of the concrete lining 13 is typically 300mm, with horizontal joint lengths set at 15-20m. This joint design effectively reduces shrinkage cracks in the concrete caused by factors such as temperature changes. During construction, the concrete lining 13 is poured vertically in layers, typically with each layer being 6m high. This layered pouring method facilitates quality control and ensures the compactness of the concrete. Notably, the steel bars in the concrete lining 13 overlap with the anchorages 15 of the steel lining 12. This connection method further strengthens the collaborative working ability between the steel lining 12 and the concrete lining 13, forming an organic whole that jointly resists external forces.

[0025] Furthermore, monitoring elements 16 are fixedly installed on the connector 14, with each monitoring element 16 fixedly installed on the non-bending section of the connector 14. The monitoring elements 16 are connected to the data acquisition device MCU via cables, and the MCU reads the data. All the rebar gauges embedded in the connector, the connecting cables, and the data acquisition device MCU together constitute the monitoring system, with the pre-embedded sets of rebar gauges being the core components. This monitoring system can monitor the lining structure, track the stress changes and operating status of the structure in real time, and provide accurate and effective technical parameters for subsequent operation and management, facilitating timely understanding of the structural condition and enabling scientific and reasonable maintenance and management by staff.

[0026] Specifically, the MCU (Microcontroller Unit) in the data acquisition device is a microcomputer chip integrating a central processing unit, memory, and input / output interfaces. It is the core control and data processing component of the monitoring system. When the monitoring device 16 senses relevant information about the lining structure, it converts this information into electrical signals and transmits them to the MCU via cable. After receiving the signal, the MCU first performs preliminary filtering and amplification to remove interference signals and enhance the stability and accuracy of the effective signal. Subsequently, it analyzes and calculates the processed signal according to a preset program, converting the original electrical signal into physical quantity data that can be directly used for monitoring, such as stress and strain. The MCU undertakes key tasks such as data acquisition, processing, and storage, and can accurately read and integrate monitoring information. In the entire monitoring system, the MCU acts as the "central nervous system," coordinating the efficient operation of components such as the rebar gauge and connecting cables to ensure the accurate acquisition of lining structure monitoring data, providing stable and reliable information support for subsequent technical analysis in operation and management.

[0027] Furthermore, the monitoring element 16 is a rebar gauge, which is a vibrating wire instrument with specifications matching the diameter of the rebar. Its measurement range is 0–400 MPa, with an accuracy of ±0.25%FS, a sensitivity of 0.016%FS, and an applicable temperature range of -20ºC to +80ºC. When the monitoring element 16 detects relevant information about the lining structure at the non-bending section of the connector 14, it converts this information into an electrical signal and transmits it to the data acquisition device MCU via a cable.

[0028] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
