As China wraps up the issuance of 1.3 trillion yuan in ultra-long-term special treasury bonds in 2025 – a 3000 billion yuan increase from the previous year – the water conservancy sector has emerged as the primary beneficiary of this capital injection . These funds, earmarked for "major national projects" including large irrigation districts, water diversion projects, and reservoir reinforcement, have accelerated construction schedules nationwide. For the grouting pipe industry, this policy impetus has translated into a striking 20% year-on-year surge in foundation grouting pipe procurement, with steel grouting pipe and perforated grouting pipe becoming the most sought-after variants in water conservancy applications .

The 2025 ultra-long-term special treasury bonds have addressed a long-standing pain point for water conservancy projects: insufficient capital for foundation reinforcement. Unlike general fiscal funds, these bonds are allocated directly to projects with clear construction timelines and tangible public benefits, making them ideal for large-scale water infrastructure requiring stable, long-term investment .

A prime example is the Jiwan Reservoir project in Sanmenxia, Henan Province. After years of delays due to a 1.5 billion yuan funding gap, the project secured 407 million yuan in ultra-long-term treasury bond support, immediately kickstarting foundation reinforcement work . By October 2025, the project had procured 1,200 tons of steel grouting pipe – a 22% increase from the original procurement plan – to stabilize the dam’s soft soil foundation. Similarly, the Yangtze River embankment reinforcement project in Hubei, which received 890 million yuan in bond funds, doubled its order for perforated grouting pipe to 30,000 meters, as accelerated construction required more efficient soil consolidation solutions .

The National Development and Reform Commission (NDRC) reports that 800 billion yuan of the 1.3 trillion yuan bond quota has been allocated to 1,459 water conservancy and transportation projects, driving over 1 trillion yuan in total investment . For foundation grouting pipe manufacturers, this means a sustained procurement boom: every 100 million yuan invested in water conservancy foundations generates an average demand for 500 tons of grouting pipes .

Water conservancy structures like dams, levees, and irrigation channels demand rigorous foundation stability to withstand long-term water pressure and geological shifts. Foundation grouting pipe plays an irreplaceable role in reinforcing soft soil, plugging seepage channels, and enhancing soil bearing capacity – and recent technological upgrades have made these pipes even more indispensable.

Material innovations have expanded application scope. Traditional cement-based grouting pipes often suffered from clogging and uneven slurry diffusion, but modern steel grouting pipe blended with 3% bentonite and 0.5% water reducer has improved slurry fluidity by 33%, cutting single-hole grouting time by 20% . For ecologically sensitive water projects, bio-based composite grouting pipes using modified starch instead of 30% cement have achieved pH neutrality (8.2 vs. 12.5 for traditional pipes), meeting zero-pollution requirements in nature reserves .

Technological 适配 has boosted efficiency. In the Yellow River levee reinforcement project in Shandong, perforated grouting pipe paired with dual-cylinder hydraulic pumps (reducing pressure fluctuation from ±0.5MPa to ±0.2MPa) has improved grouting uniformity by 40% and lowered slurry waste by 17% . Intelligent systems with IoT sensors now monitor grout diffusion in real time: in a Hebei reservoir foundation project, 120 embedded sensors identified three weak zones for targeted replenishment, ensuring all test points exceeded design strength by 10% .

These advancements have made foundation grouting pipe a standard in water conservancy construction. Industry data shows that grouting-related costs now account for 15-20% of total foundation investment in large reservoirs – up from 10% in 2023 – reflecting growing reliance on high-performance grouting solutions .

The impact of ultra-long-term treasury bonds will extend beyond 2025. As of late October, over 420 billion yuan in unused bond quota remains available for water conservancy projects, ensuring continuous procurement momentum for foundation grouting pipe . Meanwhile, the NDRC’s "2026 Water Conservancy Modernization Plan" includes 50 new large-scale irrigation district projects, each requiring an average of 2,000 tons of steel grouting pipe for foundation work .

Overseas markets are also tapping into China’s advanced grouting pipe technology. Southeast Asian countries like Vietnam and Indonesia, which face similar water infrastructure challenges, have increased imports of Chinese pre-injection pipe by 25% year-on-year. The Jakarta flood control project, for instance, recently ordered 8,000 meters of corrosion-resistant steel grouting pipe – citing its proven performance in China’s Yangtze River projects .

For foundation grouting pipe enterprises, the ultra-long-term special treasury bond wave is more than a short-term demand boost – it’s a catalyst for product upgrading and global expansion. By focusing on high-pressure steel variants, eco-friendly materials, and intelligent monitoring integration, manufacturers can not only capture domestic policy dividends but also gain a foothold in the growing global water infrastructure market. As 2025 draws to a close, the message is clear: water conservancy-driven demand will remain the industry’s strongest growth engine in 2026.
