Abstract
Description
Technical Field
[0001] This application relates to the field of concrete construction technology, specifically to a water tank seepage prevention monitoring structure and its construction method. Background Technology
[0002] Water plant structures are constantly submerged in water during operation, and their sidewalls are high and thin, constituting high-strength thin-walled structures. Settlement joints and construction joints on the foundation slab and sidewalls are prone to leakage under water pressure. This is especially true when the flocculation tank and clear water tank are stacked, with a maximum designed storage capacity of 20,000 to 30,000 tons, generating significant lateral and vertical water pressure. The need for enhanced seepage prevention at settlement joints and construction joints, particularly for the elevated foundation slab of the upper flocculation tank, is paramount. These vulnerable areas are key areas of focus for leakage monitoring.
[0003] Currently, the bottom slab of water tanks, or the elevated bottom slab of stacked water tanks, typically uses a conventional embedded rubber waterstop as a waterproofing structure to prevent seepage at settlement joints and construction joints. This waterproofing coefficient is relatively low, and once the tank is full, leaks at settlement joints and construction joints are difficult to treat, requiring significant costs and time. Furthermore, the lack of leakage monitoring devices means that alarms cannot be sent promptly when leaks occur, potentially leading to serious losses.
[0004] Current leakage monitoring devices require highly technical instruments, are expensive, complex to install, and have long construction periods. For example, patent CN201811408202.4 discloses an advanced monitoring and early warning device for leakage at construction joints of underground concrete structures, including a detection device, a data acquisition instrument, and a computer terminal. The detection device comprises multiple components such as a moisture-proof layer, water-swellable rubber, a miniature pressure box, a pressure box lead pipe, and a pressure box lead wire. In this monitoring and early warning device, the water-swellable rubber expands in volume when exposed to leaking water. The miniature pressure box detects the pressure change at the water-swellable rubber, and the data acquisition instrument collects the pressure signal and transmits it to the computer terminal. The pressure-leakage curve displayed on the computer terminal is used to determine the leakage amount and trigger an alarm. This monitoring and early warning device requires highly technical instruments and is expensive. The miniature pressure box needs to be tightly fitted to the top of the water-swellable rubber, making installation complex and the construction period long; if the fit is not tight, the pressure detection may be inaccurate, affecting the monitoring results. Summary of the Invention

[0012] In some embodiments of this application, the alarm device includes an indicator light that illuminates when there is no water seepage at the water-sensitive, color-changing, and expansion sealing strip, and extinguishes after water seepage at the water-sensitive, color-changing, and expansion sealing strip. The water seepage signal is indicated by the indicator light going out.
[0013] In some embodiments of this application, the alarm device includes: Metal wires are used to connect each component in the alarm device to form a closed circuit; And a short-circuit protector, which cuts off the power supply to the indicator light after the metal wire of the water-sensitive, color-changing, and expanding water-stop strip short-circuits due to water seepage.
[0014] In some embodiments of this application, the material of the metal wire is copper or lead.
[0015] In some embodiments of this application, the metal wire is laid in conjunction with the water-sensitive color-changing and expanding waterproof strip, and the open end is connected to the control circuit board, alarm light, power supply, indicator light and short circuit protector to form a closed circuit.
[0016] In some embodiments of this application, the short-circuit protector is integrated with the power supply.
[0017] In some embodiments of this application, the control circuit board, alarm light, power supply, indicator light, and short-circuit protector are located outside the water tank.
[0018] In some embodiments of this application, the water-sensitive color-changing and swelling waterstop strip is laid on the upper surface of the embedded rubber waterstop.
[0019] In some embodiments of this application, the external rubber waterstop is adhered to the concrete slab surface on both sides of the joint and fixed by stainless steel pressure strips and stainless steel expansion bolts.
[0020] In some embodiments of this application, the alarm device is provided at each slit in the pool.
[0021] In some embodiments of this application, the voltage of the power supply is 24V.
[0022] In some embodiments of this application, the seam is located on the bottom plate and / or side wall of the pool.
[0023] In some embodiments of this application, the water tank is a stacked water tank.
[0024] In some embodiments of this application, the joint is a settlement joint, construction joint, or expansion joint.
[0025] According to a second aspect of this application, a construction method for a water tank seepage prevention monitoring structure is provided, comprising the following steps: A water-sensitive color-changing ink is brushed or sprayed onto the surface of the water-swellable waterstop strip to form a color-changing layer, thus obtaining the water-sensitive color-changing swelling waterstop strip. After fixing the embedded rubber waterstop at the predetermined position of the joint, concrete is poured to the bottom of the joint to form a concrete structure, so that the embedded rubber waterstop is embedded in the concrete structure, with its upper surface exposed and its two sides extending into the concrete slabs on both sides of the joint respectively. The water-sensitive color-changing and swelling waterstop strip is continuously laid along the entire length of the seam on the upper surface of the embedded rubber waterstop. Apply external rubber waterstops to the concrete slab surfaces on both sides of the joint, covering the top of the joint. The control circuit board, alarm lights, and power supply are installed on the outside of the water tank.
[0026] In some embodiments of this application, the following steps are also included: Metal wires are laid in a U-shape along one end and both sides of the water-sensitive color-changing and expanding waterstop strip and fixed in place; The spacing between fixed points shall not exceed 50cm; Additionally, the open end of the U-shaped metal wire is connected to the control circuit board, power supply, alarm light, indicator light, and short-circuit protector located outside the water tank to form a closed circuit.
[0027] In some embodiments of this application, the concrete slab surfaces on both sides of the joint are first ground, and then the external rubber waterstop is pasted on the ground area.

The stainless steel expansion bolts extend no more than 15mm above the concrete slab.
[0028] Beneficial technical effects of the present invention This invention discloses a water tank seepage prevention and monitoring structure that simultaneously integrates seepage prevention, monitoring, and alarm functions. Compared to embedded rubber waterstops, the double-layer seepage prevention waterstop provides an additional layer of protection and reduces the risk of seepage associated with embedded rubber waterstops. Furthermore, this structure incorporates a water-sensitive color-changing and expanding waterstop strip within the double-layer seepage prevention structure as a seepage detector. Upon seepage, it sends a seepage signal to the control circuit board, triggering an alarm light to alert staff that seepage has occurred at the seam in the water tank. Moreover, this expanding waterstop strip changes color upon contact with water; the location of the leak can be determined by observing the color change simply by opening the external rubber waterstop. Additionally, the water-sensitive color-changing expanding waterstop strip at the seepage point can expand temporarily to stop the seepage, preventing further downward spread. Therefore, the seepage monitoring structure of this embodiment indicates whether there is a leak by using an alarm light and indicates the location of the leak by using the color-changing position of the water-swellable sealing strip. Compared with the existing seepage monitoring technology that determines whether there is a leak by measuring the pressure signal at the water-swellable sealing strip and using the pressure and seepage curve, it has the advantages of intuitive alarm method, low cost, low equipment technical requirements, strong applicability, convenient installation, short construction period, and accurate location of the leak. It is suitable for seepage alarm at settlement joints, construction joints, expansion joints and other joints with double-layer seepage prevention.
[0029] The construction method of a water tank seepage prevention monitoring structure according to an embodiment of the present invention only requires adding a step of continuously laying water-sensitive color-changing and expanding water-stop strips on the embedded rubber waterstop strip on the basis of conventional seepage prevention construction. No special requirements such as tight bonding are required. Other components of the alarm device can be installed on the outside of the tank after the seepage prevention construction inside the tank is completed. The operation is simple, the installation is convenient, and the construction period is short. Attached Figure Description

Detailed Implementation
[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0033] Example 1 like Figure 3 As shown in the figure, this embodiment provides a water tank settlement joint seepage prevention monitoring structure, including a concrete structure 12, an embedded rubber waterstop 5, an external rubber waterstop 4, and an alarm device. The concrete structure 12 fills the bottom of the settlement joint 11. The embedded rubber waterstop 5 is embedded in the concrete structure 12, with its upper surface exposed and its two sides extending into the concrete slabs 13 on both sides of the settlement joint 11. The external rubber waterstop 4 is laid on the surface of the concrete slabs 13 on both sides of the settlement joint 11, covering the top of the settlement joint 11.
[0034] like Figure 1-3 As shown, the alarm device includes a water-sensitive color-changing and swelling waterstop strip 6, a control circuit board 9, an alarm light 3, and a power supply 1. The water-sensitive color-changing and swelling waterstop strip 6 is located between the embedded rubber waterstop 5 and the external rubber waterstop 4. In this application, it is continuously laid along the entire length of the settlement joint 11 on the upper surface of the embedded rubber waterstop 5. The water-sensitive color-changing and swelling waterstop strip 6 emits a seepage signal and changes color when seepage occurs. The control circuit board 9 receives the seepage signal from the water-sensitive color-changing and swelling waterstop strip 6 and sends an indication to the alarm light 3. The alarm light 3 receives the indication from the control circuit board 9 and illuminates. The power supply 1 supplies power to the alarm device.
[0035] In some embodiments of this application, the water-sensitive color-changing and swelling waterstop strip 6 is a water-sensitive and swelling waterstop strip with a color-changing layer on its surface, and the material of the color-changing layer is water-sensitive color-changing ink.
[0036] In some embodiments of this application, the water-sensitive ink is a colorless, water-soluble ink that is transparent when not in contact with water, displaying the black color of the waterstop strip itself, and turns red when in contact with water.
[0037] In some embodiments of this application, the main components of the water-sensitive color-changing ink are water-based acrylate, aluminum chloride, phenolphthalein, ethylene-vinyl acetate copolymer, water, and ethanol. By selecting phenolphthalein, a charged pH indicator, the color change from colorless to red is achieved through charge migration caused by pH changes. This color change is irreversible.
[0038] In some embodiments of this application, the main components of the water-sensitive color-changing ink are water-based polyurethane emulsion, polyethylene wax emulsion, wetting agent, defoamer, phenolphthalein, phosphoric acid, and ethanol. When the water-sensitive color-changing ink comes into contact with water, the color developer phosphoric acid in the system can hydrolyze to release hydrogen ions, and the color developer phenolphthalein changes color under the condition of pH change. The ink does not fade after color change, and the change is irreversible.
[0039] In some embodiments of this application, the water-sensitive ink is a white ink. It is white when not in contact with water, becomes transparent when in contact with water, revealing the black color of the waterstop strip itself, and can return to its original state after drying, which is a reversible color change.
[0040] In some embodiments of this application, the water-sensitive color-changing and swelling waterstop strip 6 is pasted and fixed to the upper surface of the embedded rubber waterstop strip 5.
[0041] In some embodiments of this application, the alarm device includes an indicator light 2, which illuminates when there is no water seepage at the water-sensitive, color-changing, and expansion-resistant waterproofing strip 6, and extinguishes after water seepage occurs at the water-sensitive, color-changing, and expansion-resistant waterproofing strip 6. The water seepage signal is indicated by the indicator light 2 extinguishing.
[0042] In some embodiments of this application, the alarm device further includes a metal wire 7 and a short-circuit protector. The metal wire 7 connects each component of the alarm device to form a closed circuit. Specifically, the metal wire 7 is laid close to the water-sensitive color-changing and swelling waterproof strip 6. Preferably, it is laid in a U-shape along one end and both sides of the water-sensitive color-changing and swelling waterproof strip 6, with the open end connecting the control circuit board 9, power supply 1, indicator light 2, alarm light 3, and short-circuit protector to form a closed circuit. The short-circuit protector is integrated with the power supply 1. After water seeps into the water-sensitive color-changing and swelling waterproof strip 6 and short-circuits the metal wire 7, the power supply to the indicator light 2 is cut off.
[0043] In some embodiments of this application, power supply 1 includes a main power supply and a backup power supply, wherein the main power supply is used to power indicator light 2, and the backup power supply powers alarm light 3 when the short-circuit protector cuts off the power supply to indicator light 2.
[0044] In some embodiments of this application, the voltage of power supply 1 is 24V.
[0045] In some embodiments of this application, the metal wire 7 is made of copper.
[0046] In some embodiments of this application, the water tank 14 is a superimposed water tank, and the settlement joint 11 is located on the bottom plate and side wall of the water tank 14.
[0047] In some embodiments of this application, an alarm device as described above is installed at each settlement joint 11 in the water tank 14 and is numbered accordingly.
[0048] In some embodiments of this application, the control circuit board 9, alarm light 3, power supply 1, indicator light 2, and short-circuit protector are located outside the pool 14, such as on the top and outside of the side wall.
[0049] In some embodiments of this application, the external rubber waterstop 4 is adhered to the surface of the concrete slab 13 on both sides of the settlement joint 11 and fixed by stainless steel pressure strips 8 and stainless steel expansion bolts 10.
[0050] The working principle of the above alarm device is as follows: When there is no water seepage at settlement joint 11, the alarm device only illuminates the green indicator light 2. If water seepage occurs at settlement joint 11, the metal wire 7 at the water-sensitive, color-changing, expandable sealing strip 6 short-circuits upon contact with water, and the short-circuit protector cuts off the power to indicator light 2, causing it to extinguish. The control circuit board 9 receives the seepage signal from the water-sensitive, color-changing, expandable sealing strip 6 (indicator light off) and sends an instruction to alarm light 3, which illuminates (red). Simultaneously, the water-sensitive, color-changing, expandable sealing strip 6 at the seepage point expands temporarily to stop the water seepage and changes color. Workers can locate the seeping settlement joint 11 by the number of the illuminated alarm light 3. After opening the corresponding external rubber sealing strip 4, the specific seepage location can be determined by the color change.
[0051] After leakage is repaired, for water-sensitive, reversibly discolored, swellable waterstops 6 should be allowed to air dry naturally or dried with hot air at 30-50 degrees Celsius. The water-sensitive, swellable waterstops 6 will then return to their original state and can be reused. For water-sensitive, swellable waterstops 6 with irreversible discoloration, they should be replaced before installation.
[0052] Example 2 This embodiment provides a construction method for a water tank settlement joint seepage prevention monitoring structure, including the following steps: Step 1: Apply water-sensitive color-changing ink to the surface of the water-swellable waterstop strip by brushing or spraying to form a color-changing layer, thus obtaining the water-sensitive color-changing swelling waterstop strip. In some embodiments of this application, the length of the expansion seal strip is the same as the length of the settlement joint.
[0053] In some embodiments of this application, the thickness of the water-sensitive color-changing ink is 3-5 mm.
[0054] Step 2: Continuously lay metal wires along one end and both sides of the water-sensitive color-changing expansion seal strip, so that the wires are arranged in a U-shape on the expansion seal strip, thus obtaining a water-sensitive color-changing expansion seal strip with wires. In some embodiments of this application, the wires are fixed to the expansion sealing strip with tape, and the distance between the fixing points is no more than 50cm.
[0055] Step 3: After fixing the embedded rubber waterstop at the predetermined position in the settlement joint, pour concrete into the bottom of the settlement joint to form a concrete structure, so that the embedded rubber waterstop is embedded in the concrete structure, with its upper surface exposed and its two sides extending into the concrete slabs on both sides of the settlement joint. In some embodiments of this application, the embedded rubber waterstop is cast at the center of the concrete structure.
[0056] Step 4: Lay the water-resistant, color-changing, and expanding waterstop strip with a conductor continuously along the entire length of the settlement joint on the upper surface of the embedded rubber waterstop. In this application, the wires and the water-sensitive, color-changing, and swelling waterstop strip are glued to the embedded rubber waterstop strip. Step 5: Apply the external rubber waterstop to the concrete slab surface on both sides of the settlement joint, covering the top of the settlement joint. In some embodiments of this application, the concrete slab surfaces on both sides of the settlement joint are first ground smooth and the dust is cleaned; then structural adhesive is applied to adhere the external rubber waterstop to the concrete slab; finally, stainless steel expansion bolts and stainless steel pressure strips are used to firmly fix both sides of the surface rubber waterstop to the concrete slab, further enhancing the sealing performance and connection strength between the external rubber waterstop and the concrete slab.
[0057] In some embodiments of this application, the grinding width is consistent with the pasting width. The stainless steel pressure strip has a width of 3cm to 5cm and a thickness of not less than 2mm. The outer side of the stainless steel pressure strip is flush with the external rubber waterstop. The stainless steel expansion bolts protrude no more than 15mm above the concrete slab to avoid affecting the subsequent removal of silt from the bottom of the pool.
[0058] Step Six: Install other components of the alarm device on the outside of the water tank. In some embodiments of this application, the open end of the U-shaped metal wire is connected to a power supply, short-circuit protector, indicator light, alarm light, and control circuit board (not shown in the figure) located outside the water tank to form a closed circuit, thus completing the installation of the entire alarm device. The control circuit board, alarm light, and indicator light are located at the top of the side wall, while the power supply and short-circuit protector are located outside the side wall.
