PRODUCT DETAILS

Tensioning Prestressed Tendons

Anchoring and Locking

After tensioning is complete, the load is held in place; in conjunction with anchorage devices, the prestressed tendons are locked to maintain the designed tension.

Unanchoring and Relaxing

Loosening or releasing the prestressing tendons during construction adjustments, inspections, or demolition.

Testing and Calibration

Used for tensile testing of anchorages, steel strands, and anchor cables, as well as for calibrating jacks and hydraulic pumps.

Reinforcement and Jacking

Structural reinforcement, external prestressing, and jacking to correct misalignment of structural members.

Scope of Application (Applicable Scenarios)

1. Bridge Engineering (Primary Application)

- Precast T-beams, box girders, hollow slabs, U-beams

- Continuous beams, cast-in-place box girders, ramp bridges, elevated bridges

- High-speed rail/subway track beams and track slabs

- Cable-stayed bridges, suspension bridges, and tied-arch bridges (tensioning of anchor cables/cables)

2. Building Construction

- Long-span beams, floor slabs, and transfer floors

- Large-span structures such as stadiums, airports, and convention centers

- Construction of prestressed beams and slabs in high-rise buildings

- Reinforcement of existing buildings, external prestressing retrofitting

3. Water Resources and Hydropower

- Anchor cables for dams, gate piers, and spillways

- Prestressing for hydropower plant buildings and pressure pipelines

- Crack-resistant tensioning for reservoirs, aqueducts, and impermeable structures

4. Excavation Pits, Slopes, and Tunnels

- Tensioning of anchor cables and bolts for deep excavation shoring

- Anchoring for mountain slopes and landslide control

- Prestressing reinforcement for tunnel segments and linings

5. Prefabricated Component Production

- Pile pipes, utility poles, railway sleepers, and double-T slabs

- Pre-tensioned formwork and post-tensioned precast components

6. Other Projects

- Nuclear power plants, large storage silos, and heavy equipment foundations

- Static load testing, anchorage testing, and project acceptance

Applicable Tensioning Methods

- Post-tensioning: For cast-in-place or precast beams on site—insert tendons → tension → anchor (mainstream)

- Pre-tensioning: Tension tendons on the formwork first, then pour concrete, and finally apply tension

- External prestressing: Tensioning and reinforcement applied to the exterior of the structure

- Single-strand/bundle tensioning: Tensioning of individual steel strands or multiple strands as a single unit

Summary

Applications: Pulling steel strands, applying prestress, locking, releasing tension, and inspection.

Scope: Almost all prestressed concrete projects, including bridges, buildings, water conservancy projects, excavation slopes, tunnels, precast components, and structural reinforcement.

Prototype with dual circuits

Solenoid-operated single-circuit oil pump = a hydraulic power unit featuring a single oil circuit (with only one high-pressure outlet and return line) and an integrated solenoid directional control/unloading valve, specifically designed for precise, electronically controlled, and pressure-maintaining operation of a single actuator (single jack or single cylinder).

Integrated Mortar Pump

The integrated design of the mixing and storage tank and pumping mechanism eliminates the need for a separate mixer. The feeding, mixing and conveying are completed in one go. It can transport cement mortar, cement slurry and grouting material, and is mostly used in small-scale grouting, repair, plastering and prestressed assisted grouting construction site scenarios.

Twin-Cylinder Slurry Pump

The dual-cylinder grouting pump uses two oil cylinders to alternately suck and discharge grout, resulting in continuous discharge without pulses, high pressure, and stable flow. Compared with the single-cylinder pump, it has higher efficiency and better pressure stabilization effect, making it the main equipment for large-scale grouting projects in roads, bridges, tunnels, mines, and foundation pits.
