喉管滲漏漏水檢測
Water Leakage Detection

設施老化與潛在風險
大多數管道（不論用途）的設計使用壽命通常約為 25 年。隨著管道老化，內部結構會逐漸惡化並產生裂縫。最初細微的滲漏若未及時處理，往往會演變成災難性的爆裂。更嚴重的是，持續的滲漏會導致水土流失，進而引發地面塌陷或山泥傾瀉等公共安全事故。
先進檢測技術：漏水噪聲相關分析 (Leak Noise Correlation)
​我們採用先進的洩漏噪聲相關儀 (Leak Noise Correlator)。這是一種高精密電子裝置，專門用於探測加壓水管或氣體管道的滲漏位置：

• 技術原理： 透過在管道不同位置放置高靈敏度聲學傳感器，記錄滲漏產生的異常聲波。
• 精準計算： 系統根據管道材質、管徑及傳感器間距，自動計算聲波傳遞速差，從而精確推算出滲漏點。
• 二次定位： 在初步定位後，我們會配合洩漏噪聲探測儀 (Ground Microphone) 進行地表精確複核，確保試孔挖掘與維修工作能精準進行，大幅降低開挖成本。

Infrastructure Aging and Risk Management
Most underground pipelines, regardless of their application, have a design life of approximately 25 years. As these assets age, structural deterioration often begins with hairline cracks and minor leakages. If left unaddressed, these issues can escalate into catastrophic failures. Persistent leaks also lead to internal soil erosion, which is a primary cause of ground subsidence (sinkholes) and landslides.
Advanced Technology: Leak Noise Correlation We utilize state-of-the-art Leak Noise Correlators—sophisticated electronic systems designed to detect and locate leaks in pressurized water or gas mains:

• Methodology: High-sensitivity acoustic sensors are placed at two or more points along the pipeline to record the sound frequencies generated by a leak.
• Automated Analysis: By inputting variables such as pipe material, diameter, and sensor distance, the system’s algorithm calculates the precise location of the leak based on sound velocity.
• Pinpoint Verification: Once the initial location is identified, we employ Electronic Ground Microphones (Leak Detectors) for surface-level pinpointing. This ensures that trial pit excavations and subsequent repairs are conducted with surgical precision, minimizing disruption and costs.
