How to ensure that the width and thickness of the waterstop are produced within the specified size?
Introduction
Waterstops play a crucial role in various infrastructure projects, including underground structures, tunnels, sewage treatment plants, water conservation systems, and subway constructions. They are typically used during the concrete casting process for expansion joints such as gates, dam bases, construction joints, and underground buildings. By ensuring tight sealing, they significantly contribute to the durability and service life of these critical structures. Given the importance of these projects, accurate measurement of waterstop dimensions during production is essential. To meet this need, specialized tools like the waterstop tape width meter and waterstop thickness gauge have been developed.
1. Waterstop Width and Thickness Standards
* When the water pressure is less than 4m and the horizontal and vertical deformation does not exceed 10mm, the waterstop width should be at least 200mm, with a minimum thickness of 5mm;
* For water pressure between 4-8m and deformation up to 30mm, the CB-type waterstop must have a width of no less than 300mm and a thickness of at least 6mm;
* When the water pressure exceeds 8m and the deformation is more than 30mm, the CB-type waterstop should have a width of at least 350mm and a thickness of no less than 8mm;
* In cases where the water pressure is under 8m and the horizontal deformation is less than 20mm with no vertical deformation, the CB-type waterstop should have a width of at least 200mm and a thickness of 5mm. Additionally, if the structural section is larger than 500mm, the waterstop width should be at least 300mm. The bending radius when using the CB-type waterstop should not be less than 300mm.
2. Waterstop Tape Width Meter
The waterstop tape width meter is a high-precision measuring device designed for real-time online detection of waterstop tapes. It operates at a frequency of 500 Hz, enabling fast and continuous width measurements. This device uses photoelectric principles, with a dual-barrel probe that allows adjustable pitch for multi-standard measurements. When the waterstop specifications change, the probe width can be adjusted accordingly, offering a wide measuring range and an accuracy of 0.05mm.
The width meter consists of an optical imaging system, a CCD-based photoelectric conversion device, a signal processing unit, and a display and alarm system. If the measured width exceeds the set tolerance, it triggers an audible and visual alarm. This automated system enables real-time monitoring, measurement, and display, reducing manual workload and improving both product quality and yield.
3. Waterstop Thickness Gauge
Waterstops come in various types, such as bridge, mountain, P, R, U, Z, B, T, H, E, Q, etc., and are not always straight. To measure their thickness accurately, a waterstop thickness gauge has been developed. The figure below shows some common waterstop specifications, while the thickness gauge can measure dimensions such as δ, H1, H2, t, etc., in real time.
Based on laser thickness measurement technology, the waterstop thickness gauge offers high precision without environmental pollution or radiation, making it ideal for modern industrial applications. It features three adjustable laser probes for fixed-point or scanning measurements. With a measuring accuracy of ±0.05 mm and a frequency of 100 Hz, it provides continuous, high-precision online detection.
To enhance user experience, the thickness gauge includes a professional software system that displays a non-automatically generated cross-sectional view of the waterstop. It also shows real-time data, fluctuation curves, and allows data transfer to other computers. An external large display, control cabinet display, and LCD screen provide clear readings of product specifications, standard thickness, rib thickness, and more.
During scanning, the interface displays the shape map and corresponding thickness fluctuation curve. If the measured value falls within the acceptable range, it appears in green; if it exceeds the limit, it turns red, providing immediate visual feedback.
Conclusion
The waterstop tape width meter and thickness gauge are essential tools in the production of waterstop belts. They enable real-time detection of width and thickness, greatly enhancing quality control and efficiency. These devices improve detection speed, increase the number of measurement points, and ensure high-precision, continuous, and rapid inspection. As a result, they significantly contribute to the overall quality and reliability of waterstop products in critical infrastructure projects.
