水管資產管理 我們致力提升管理龐大水管資產的質素。水管爆裂的個案數字 一直維持在低水平，在二零二二年亦只有約 36 宗。我們將繼 續推行以風險為本的水管資產管理策略，以維持政府供水網絡 的健康狀況，減低水管爆裂或滲漏的風險。 我們會根據水管爆裂或滲漏的後果、水管使用年期和物料、過 往爆裂或滲漏記錄、周邊環境等各項因素，為高風險的水管優 先進行改善工程，包括進行更換或修復水管，以減低水管爆裂 或滲漏的風險。此外，我們亦會為位於「爆喉熱點」（即重複 出現水管爆裂的段落）的水管進行改善工程。 Water Main Asset Management We are committed to enhancing the management of our vast water main assets. Water main burst cases remain at a relatively low level. In 2022, 36 main burst cases were recorded. We will continue to implement a risk-based water main asset management strategy to maintain the healthiness of the government water supply networks and to reduce the risk of water main bursts or leaks. Taking into account various factors including the consequences of bursts or leaks, ages and materials of the water mains, past records of bursts or leaks, surrounding environment, etc., we accord priorities for improvement works to those water mains assessed with high risk, including replacement or rehabilitation to reduce the risk of water main bursts or leaks. In addition, we will carry out improvement works to water mains in “main burst hot spots” (i.e. sections with repeated water main bursts). 利用先進技術檢查水管 地下水管結構複雜，而維修人員在管道內工作亦存在安全 與健康隱患，對管道檢測構成了挑戰。為使地下水管檢測 工作能以更有效和安全的方式進行，並提高準確率，水務 署研發「管道檢測機械人」及相關的協作系統，為未來全 港不同物料和直徑的水管檢測工作作好準備。 水務署已進行使用機械人技術檢測直徑 600 毫米金屬水管 健康狀況的可行性研究，在無水的管道內，利用非破壞性 水管檢查方法，檢測水管的餘壁厚度、表面有否裂紋，以 及水管表面和內壁的情況。利用機械人設計、傳感器、影 像和人工智能等一系列先進技術，管道檢測機械人能適應 香港市區擠迫的地下設施中水管走線和直徑轉變等常見的 特徵，為檢查水管的狀況及其結構的完整性提供所需的啟 發和技術。 管道檢測機械人能 在多種地下環境 下，在水管內以不 同角度（包括90 度轉彎）單向高效 行駛超過150 米。 Advanced Technologies for Water Mains Inspection Complicated configurations of underground water mains, coupled with the safety and health hazards to the maintenance personnel, have posed challenges to the in-line inspection of water mains. With a view to enhancing the efficiency and safety of underground water mains inspection work with higher accuracy rate, the WSD has conducted an investigation for developing the “In-line Inspection Robot” and relevant collaborative systems, paving the way for the territory-wide application for inspecting different materials and diameters of water mains in future. Feasibility study on the viability of using robotic technologies has been conducted for assessing the health conditions of metallic water mains of 600 mm diameter, viz. residual wall thickness of pipes, presence of surface cracks and conditions of pipes and linings, by non-destructive testing methods in dry main condition. With the use of advanced technologies such as robotics design, sensors, imaging and artificial intelligence, the In-line Inspection Robot can adapt to the sharp changes in pipe direction and diameter which are common features of water mains in the congested underground utilities in the urban areas of Hong Kong, providing insights and skills to inspect the conditions and assess the structural integrity of the pipes. Operating under various underground conditions, the In-line Inspection Robot can navigate efficiently along the interior of water mains in different angles such as 90-degree bends in a single pass to reach over a distance of 150 meters. 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 56 Scale up 升 級 開 拓
