Description

Technical Field

[0001] This utility model relates to the field of seepage prevention and water stopping technology, and in particular to a seepage prevention and water stopping structure for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to mitigate water-related disasters and develop and utilize water resources. They are categorized by their service objectives, including flood control projects, farmland irrigation projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and coastal reclamation projects. Water conservancy projects that simultaneously serve multiple purposes such as flood control, water supply, irrigation, and power generation are called comprehensive utilization water conservancy projects. Water conservancy projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives. During the construction of water conservancy projects, seepage prevention and water sealing are crucial tasks; any leakage or seepage problems will affect the safety and service life of the water conservancy project.

[0003] However, existing water-proofing and waterproofing structures used in water conservancy projects are usually simple and fixed, making it difficult to monitor seepage and detect damage to the structures in a timely manner. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a seepage-proof and water-stopping structure for water conservancy projects, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a seepage-proof and water-stopping structure for water conservancy projects, including a water conservancy protection slope for water protection during water conservancy construction. The water conservancy protection slope has an internal seepage-proof wall made of concrete structure. The surface of the seepage-proof wall is covered with a multi-layer water-stopping frame made of water-stopping material. The surface of the multi-layer water-stopping frame is covered with a concrete lining surface of composite geomembrane. The internal part of the multi-layer water-stopping frame is equipped with a seepage monitoring plate for collecting and detecting seepage. A monitoring support rod is provided on one side of the seepage monitoring plate for support and fixation. An alarm device for early warning is provided at the top of the monitoring support rod. A safety cover is provided on one side of the alarm device for protection.

[0006] The above technical solution involves installing a seepage monitoring plate inside the multi-layered water-stop frame to detect water leakage. This plate monitors the internal humidity of the middle-layer waterproofing structure. Based on the detected data, an alarm is triggered, facilitating timely detection of damage to the waterproofing structure. A conventional control module connects the seepage monitoring plate and the alarm within the monitoring support rod. This module performs basic control functions such as signal processing and transmission, ensuring the system can fully realize signal collection, processing, control signal output, and alarm functions. The control module, monitoring support rod, and alarm can be powered by mains electricity or solar energy. For solar power, a series of solar power generation structures are installed on the monitoring support rod, and a protective electrical control box can be installed to protect parts of the solar power generation structure. A safety cover protects one side of the alarm. Both the monitoring support rod and the alarm are connected to the control module via cables, with the control module located inside the monitoring support rod.

[0007] Preferably, the top of the hydraulic protection slope is provided with a fixed slope surface that covers and connects the seepage prevention wall, the multi-layer water-stop frame and the concrete lining surface, and the fixed slope surface has a fixed slot for inserting a seepage monitoring plate.

[0008] The above technical solution is adopted: the top of the hydraulic protection slope is fixed to cover the seepage prevention wall, multi-layer water-stop frame and concrete lining surface in one integrated manner. The seepage monitoring plate is inserted through the fixed slot to ensure that the monitoring plate is sealed and fits the slope surface. The fixed slope surface is poured with C concrete to prevent surface water from seeping into the interior of the structure and to provide basic protection for the lower seepage prevention components.

[0009] Preferably, in any of the above embodiments, the multi-layer waterstop clamp includes a metal waterstop sheet as a base layer, an alloy waterstop rib for support, and a reinforced waterstop plate as a fixed support layer. The metal waterstop sheet is attached to the surface of the seepage-proof wall. One end of the metal waterstop sheet is fixedly connected to the alloy waterstop rib, and one end of the alloy waterstop rib is fixedly connected to the reinforced waterstop plate. One end of the metal waterstop sheet is provided with a water-guiding reinforcing strip fixedly connected to the reinforced waterstop plate. One side of the water-guiding reinforcing strip is provided with a water-guiding groove penetrating the alloy waterstop rib. The concrete lining surface is fixedly connected to the surface of the reinforced waterstop plate. The water-guiding reinforcing strip can guide seepage water in a certain area to the detection end of the seepage monitoring plate, so that the seepage monitoring plate can detect the seepage-proof and waterstop structure in a certain range. By setting seepage monitoring plates and monitoring support rods in a one-to-one correspondence, seepage monitoring plates and monitoring support rods can be set at equal intervals in water conservancy projects to monitor the seepage-proof and waterstop structure.

[0010] The above technical solution involves: metal waterstops (stainless steel) being attached to the surface of the anti-seepage wall and fixed with bolts to form the first waterstop barrier; alloy waterstop ribs (aluminum alloy) being vertically welded to the metal waterstops to enhance structural rigidity; internal water-guiding grooves guiding seepage water to the seepage monitoring plate; and reinforced waterstops (galvanized steel plates) being connected to the metal waterstops via water-guiding reinforcing strips to form a closed waterstop cavity. This, combined with the concrete lining surface (composite geomembrane + concrete), achieves multiple seepage prevention measures and reduces the permeability coefficient.

[0011] Preferably, in any of the above embodiments, the seepage monitoring plate includes a monitoring fixing plate for fixing and a humidity sensor for detecting seepage humidity. The monitoring fixing plate is fixedly connected between the metal waterstop and the reinforced waterstop. The humidity sensor is fixedly installed at the bottom of the monitoring fixing plate, and a sealing connection seat that is sealed and fitted to the hydraulic protection slope is provided at one end of the monitoring fixing plate.

[0012] The above technical solution is adopted: the monitoring fixing plate (PVC material) is sandwiched between the metal waterstop and the reinforced waterstop, the bottom humidity sensor monitors the humidity inside the waterstop cavity in real time, and the sealing connection seat (butyl rubber) ensures that the monitoring plate fits seamlessly with the water protection slope. When the humidity is high, the sensor sends a signal to the control module to trigger the alarm mechanism.

[0013] Preferably, in any of the above embodiments, the monitoring support rod is fixedly installed at the top of the hydraulic protection slope, and the top of the monitoring support rod is provided with an alarm support for supporting and fixing the alarm device.

[0014] Preferably, as described in any of the above embodiments, the alarm support includes a detachable support for support and a fastening expansion block for insertion and fixation. The detachable support is fitted onto the surface of the monitoring support rod, and a fastening expansion block penetrating the monitoring support rod is inserted into the interior of the detachable support. The alarm is fixedly installed at the bottom of the detachable support.

[0015] The above technical solution is adopted: the monitoring support rod (hot-dip galvanized steel pipe) is anchored to the top of the water conservancy protection slope, the disassembly and assembly support (ABS engineering plastic) of the top alarm support is fitted onto the support rod, and the fastening is achieved by fastening expansion blocks (nylon material) passing through the support rod. The alarm is fixed at the bottom of the disassembly and assembly support and provides audible and visual warnings after receiving signals from the control module.

[0016] Preferably, in any of the above embodiments, the safety cover includes an alarm sleeve that covers and protects the alarm, a high-strength spring for support, and a clamping plate for locking and securing the alarm. The alarm sleeve fits inside the disassembly support, and a high-strength spring is fixedly installed inside the alarm sleeve. One end of the high-strength spring is fixedly installed with a clamping plate that moves inside the alarm sleeve.

[0017] The above technical solution is adopted: the alarm cover (PC material) covers the alarm, and the internal high-strength spring pushes the clamping plate (rubber material) to engage with the disassembly support to achieve protection. The protective cover can withstand the ambient temperature, improve the impact resistance, and avoid damage to the alarm from wind, rain and ultraviolet rays.

[0018] The seepage barrier wall blocks groundwater infiltration. The multi-layered water-stop frame forms a composite barrier through metal water-stop plates, alloy water-stop ribs, and reinforced water-stop plates. The concrete lining surface is further sealed. If leakage occurs, the seepage water flows along the water guide channel to the seepage monitoring plate. The humidity sensor detects that the humidity exceeds the standard. After receiving the signal, the control module triggers the alarm at the top of the monitoring support rod to issue an audible and visual warning. The safety guard protects the alarm throughout the process to ensure a stable output of the warning signal. When the sensor or alarm needs to be replaced, the fastening expansion block is pulled out, the disassembly support is removed, the component is replaced, and the device is reset to ensure detection accuracy.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. A seepage monitoring plate is installed inside the multi-layered water-stop frame used for seepage prevention and water sealing in water conservancy projects to detect seepage. The seepage monitoring plate is used to detect the internal humidity of the middle layer of the seepage prevention and water sealing structure. The alarm is triggered based on the detected data, which facilitates the timely detection of damage to the seepage prevention and water sealing structure. This allows for timely maintenance of the seepage prevention and water sealing structure, thereby improving its stability and reliability and enhancing its safety.

[0020] 2. Install safety guards and monitoring support rods to protect and support the alarm, preventing damage from external objects or environmental factors from affecting the alarm, ensuring the accuracy and stability of the alarm information, and improving the stability of the seepage-proof and water-stopping structure.

[0036] The control module uses an STM32F103C8T6 microcontroller as the core processing unit (72MHz clock speed, 64KB Flash memory, 20KB RAM).

The engagement of alarm sleeve 81 and disassembly support 91 adopts a lip seal structure. With the preload force (50N) of high-strength spring 82, IP66 protection is achieved.

The metal water-stop plates 31 of the multi-layer water-stop frame 3 on the surface are attached to the seepage-proof wall 2 to form the first barrier. Alloy water-stop ribs 32 support and guide seepage water through the water guide channel. The reinforced water-stop plate 33 and the water-guided reinforcing strip 34 form a closed water-stop cavity. The concrete lining surface 4 further seals the cavity. The monitoring and fixing plate 51 of the seepage monitoring plate 5 is fixed between the metal water-stop plates 31 and the reinforced water-stop plate 33 to facilitate the detection of seepage water. The humidity sensor 52 detects the humidity in the water-stop cavity and transmits the data to the control module in the monitoring support rod 6. The monitoring support rod 6 supports the alarm support 9. When the humidity exceeds the standard, the control module triggers the alarm 7 for early warning.
