1. Overview<\/span><\/span><\/b><\/strong><\/p>\n

Absolutely. Bridge jacking is a highly efficient specialized technique in current infrastructure renovation. For common issues such as insufficient under-clearance leading to large trucks scraping the bridge or reduced waterway navigability due to riverbed siltation and seasonal flooding, the jacking technique offers an optimal solution that requires no demolition, has an extremely short construction period, and costs far less than rebuilding.<\/span><\/span><\/p>\n

2. Bridge Scenarios Applicable to Indonesia<\/span><\/span><\/b><\/strong><\/p>\n

Highway and Urban Overpasses (Jembatan Jalan Raya \/ Overpass): Addressing reduced underbridge clearance caused by repeated road resurfacing or meeting the Ministry of Transportation’s (Kemenhub) height restrictions for specific road grades by increasing clearance.<\/span><\/span><\/p>\n

River Navigation Bridges (Jembatan Lintas Sungai): In regions with heavy river traffic like Sumatra and Kalimantan, elevating bridge height allows larger barges (Tongkang) or vessels to pass smoothly.<\/span><\/span><\/p>\n

Low-Clearance Bridges at Flood Risk: For cities like Jakarta prone to frequent flooding, raising the entire bridge deck prevents water submersion, avoiding structural damage from buoyancy and lateral flood impact.<\/span><\/span><\/p>\n

Simply Supported and Continuous Beam Bridges (Gelagar Beton \/ Steel Girder): The most widely used bridge types with the highest technical adaptability and shortest construction periods.<\/span><\/span><\/p>\n

3. Technical Principles and Core Processes<\/span><\/span><\/b><\/strong><\/p>\n

Structural Assessment: First, conduct load-bearing verification according to Indonesia’s bridge seismic design standards (SNI 2833:2016).<\/span><\/span><\/p>\n

Synchronous Jacking: Install a PLC intelligent hydraulic synchronous jacking system at the abutment\/pier locations to achieve millimeter-level precision control, ensuring no secondary stress cracks occur in the beam during the lifting process.<\/span><\/span><\/p>\n

Pier Extension: After the beam is lifted to the predetermined height, permanent repositioning is achieved by extending the pier or replacing it with a taller bearing pad.<\/span><\/span><\/p>\n

Smooth Transition: Coordinated with the slope adjustment of the bridge approach (Oprit) to ensure driving comfort and safety.<\/span><\/span><\/p>\n

4. Significant Advantages Compared to Demolition and Reconstruction<\/span><\/span><\/b><\/strong><\/p>\n

Shortened Construction Period: Compared to demolition and reconstruction, which can take months or even a year, lifting construction typically requires only 1\/3 of the time, allowing for rapid restoration of traffic on busy road sections.<\/span><\/span><\/p>\n

Cost Reduction: The overall cost is merely 40%~70% of building a new bridge.<\/span><\/span><\/p>\n

Environmentally Friendly: Eliminates the need for large-scale demolition waste, aligning with the government’s Green Infrastructure policy.<\/span><\/span><\/p>\n

Minimal Traffic Disruption: Enables “load-bearing jacking” or short-term road closure lifting, allows uninterrupted navigation for cross-river bridges, and minimizes impact on logistics efficiency.<\/span><\/span><\/p>\n

V. Legal, Regulatory, and Constraining Factors<\/span><\/span><\/b><\/strong><\/p>\n

Compliance with Standards: The renovated bridge must undergo a reassessment of its stability in Indonesia’s high-intensity seismic zones to meet the latest safety evaluation criteria.<\/span><\/span><\/p>\n

Approval Process (Legal Aspect): For bridges involving national or provincial highways, it is necessary to report to PUPR (Ministry of Public Works and Housing) and update the relevant technical documentation according to the latest traffic standards.<\/span><\/span><\/p>\n

Not recommended situations:<\/span><\/span><\/p>\n

Severe carbonization or exposed reinforcement in the main bridge structure, or significant displacement\/tilting of foundations due to earthquakes.<\/span><\/span><\/p>\n

Severe scouring of bridge pier foundations where reinforcement costs are prohibitively high.<\/span><\/span><\/p>\n

6. Summary<\/span><\/span><\/b><\/strong><\/p>\n

With economic development increasing demands for logistics efficiency, “elevation instead of reconstruction” has become the preferred engineering solution for addressing bridge height restrictions, improving navigation standards, and adapting to climate change (sea level rise\/flooding).<\/span><\/span><\/p>\n

Expert reminder:<\/span><\/span><\/p>\n

Due to Indonesia’s high rainfall and relatively soft soil in some areas (such as alluvial plains), it is essential to strengthen the monitoring of scour depth at the bridge pier foundation before and after the bridge lifting. This ensures the overall stability of the elevated bridge during flood peaks in the rainy season.<\/span><\/span><\/p>\n
