Product Description Product Descriptionhydraulic post tensioning solid jackPrestressed solid jacks are special hydraulic equipment used in prestressed engineering. They are mainly used to apply prestressing force to prestressed tendons (such as steel strands and wire bundles). They are widely used in large-scale projects such as bridges, buildings, water conservancy projects, and railways. Their "solid" characteristics usually refer to the compact internal structure design. The core working parts (such as piston rods and cylinders) are made of solid steel to ensure high strength and stability.Working PrincipleMain Structure and Working Principle of the Prestressed Solid Jack1. Core Structure: Consists of a cylinder, solid piston rod, sealing device, oil inlet and outlet ports, and anchor connection devices. The solid piston rod directly bears the axial force during tensioning, while the cylinder provides the hydraulic driving force.2. Working Principle: High-pressure oil supplied by a hydraulic pump pushes the piston (solid piston rod) in the cylinder, causing axial displacement, which in turn causes the prestressed tendons to stretch. After reaching the designed tension force, the jack is locked, establishing prestressed stress in the structure.

High Strength and DurabilityThe solid piston rod is made of high-strength alloy steel, offering strong tensile and bending resistance. It can withstand extremely high tension forces (up to thousands of tons) and resists deformation over long periods of use, making it suitable for large-span, heavy-load projects.2. Compact Structure and Flexible OperationCompared to hollow jacks, solid structures are more compact, smaller, and lighter (relative to equipment of the same tonnage), making them easier to operate in confined spaces (such as within bridge box girders and prefabricated components of high-rise buildings), and making installation and movement more convenient.3. High PrecisionEquipped with a high-precision hydraulic control system and pressure sensor, the prestressing force can be precisely controlled (typically with an error of ≤1%), ensuring that the prestressing force meets design requirements and avoiding engineering hazards caused by under- or over-tensioning.4. Excellent Stability and SafetyThe solid structure distributes force evenly, preventing unbalanced loads or vibration during tensioning, reducing the risk of anchor slippage due to equipment sway. Furthermore, the excellent sealing performance minimizes hydraulic oil leakage and reduces maintenance costs. 5. Wide Range of ApplicationsIt is compatible with various prestressing systems (such as post-tensioning and pre-tensioning) and is compatible with steel strands and wire bundles of varying specifications, meeting the prestressing construction requirements of various projects, including bridges, tunnels, high-rise buildings, and hydropower dams.6. Easy MaintenanceThe internal structure is relatively simple, with few wearing parts. Routine maintenance primarily involves seal replacement and hydraulic oil cleaning, resulting in low maintenance costs and a long service life.applicationPrestressed solid jacks, due to their high strength, high stability, high tensioning precision, and compact structure, are widely used in various large-scale projects requiring prestressing of structural members. Specific application areas are as follows:1. Bridge Engineering- Beam Construction: In the post-tensioning construction of precast beams (such as T-beams, box beams, and simply supported beams), continuous beams, cable-stayed bridges, and suspension bridges, they are used to tension steel strands or wire bundles. By prestressing the beam, they improve its crack resistance and load-bearing capacity, and reduce subsequent deformation.- Bridge Reinforcement: When reinforcing and renovating existing bridges, external prestressing techniques are used to tension additional prestressed tendons, enhancing the overall strength of the bridge structure and extending its service life.2. Construction Engineering- High-Rise Buildings and Long-Span Structures: In frame structures, shear walls, transfer beams, and other components, prestressing reduces concrete cracks and improves the shear and flexural properties of the structure. They are suitable for long-span floor slabs and roofs (such as stadiums and exhibition centers). - Prefabricated Component Installation: In prefabricated buildings, prefabricated wall panels, composite beams, and other components often require prestressing to achieve tight connections and enhance overall rigidity.3. Water Conservancy and Power Engineering- Dams and Sluices: In hydraulic structures such as concrete dams, spillways, and sluices, prestressed tendons are tensioned to offset the tensile stress generated by water pressure, prevent structural cracking, and ensure dam stability.- Tunnels and Pipelines: Prestressed construction of tunnel linings and pressure pipes (such as water and gas pipelines) enhances structural impermeability and internal pressure resistance.4. Railway and Rail Transit Engineering- Railway Bridges and Sleepers: In high-speed and conventional railway bridges (such as box girders) and ballastless track slabs, prestressing ensures track smoothness and long-term structural stability, reducing deformation under train loads. - Subway Engineering: Prestressing is applied to precast segments or cast-in-place components in subway tunnels and station structures to resist ground and water pressure, improving structural safety.5. Geotechnical Engineering and Special Structures- Slope and Foundation Pit Support: In the reinforcement of deep foundation pits and high slopes, prestressed anchor rods and cables are tensioned, and solid jacks are used to provide stable prestressing force, enhancing the anti-slip resistance of the rock and soil.- Special Structures such as Chimneys and Cooling Towers: During the construction of the walls of large industrial chimneys and cooling towers, hoop prestressing is used to resist the tensile forces generated by the structure's own weight and external loads (such as wind loads), preventing cracking.6. Lifting and Installation Engineering- During the installation and positioning of large equipment (such as heavy machinery and steel structures), the precise tensioning capacity of solid jacks can be used to fine-tune components or temporarily secure them, ensuring installation accuracy.Company ProfileGuangxi Xiruier Intelligent Technology Co., Ltd. is a high-tech enterprise integrating R&D, manufacturing, sales, and service.
