In the construction of major infrastructure such as high-speed railways, cross sea bridges, nuclear power projects, and large-scale water conservancy facilities, prestressed anchorages serve as the core anchoring components of the prestressed system, and their quality directly affects the load-bearing capacity and long-term safety of the entire engineering structure. Once there is a quality problem with the anchor, it can lead to loss of prestress in some cases and structural failure in others, causing irreversible safety hazards. As a professional manufacturer in the field of mechanical testing in China, Jinan Xinguang Testing Machine Manufacturing Co., Ltd. (hereinafter referred to as "Xinguang") has launched a 1000 ton (10000kN) microcomputer controlled static load anchoring testing machine with more than 20 years of technical accumulation. It is designed specifically for the testing of prestressed anchors, providing high-precision and fully automatic testing solutions for anchor production enterprises' factory inspection, type testing, and large-scale engineering units' on-site acceptance.
The equipment test force reaches 10000kN, which can meet the static load anchoring performance testing of 15-37 holes and even larger specifications of prestressed anchors, fully covering the anchoring efficiency coefficient (η a) and ultimate tension (Fm) testing requirements specified in GB/T 14370-2015 standard. Whether it is the product finalization and factory inspection of anchor manufacturers, or the on-site re inspection and quality sampling of large engineering units, this equipment can provide authoritative and reliable testing data.
Core technological advantages: precision, stability, and full automation
1. High precision servo pump control, smooth and precise loading
The equipment adopts a high-precision servo pump control system, combined with microcomputer measurement and control technology, to form a fully automatic closed-loop speed control system. The loading process is smooth and impact free, meeting the strict requirements of different standards for loading speed. Whether observing deformation through slow loading or measuring ultimate tension through rapid loading, the system can respond accurately.
2. Microcomputer measurement and control, fully automatic closed-loop speed regulation
Equipped with a fully digital multi-channel closed-loop measurement and control system independently developed by Xinguang, it supports multiple control modes such as constant rate test force, constant rate stress, constant rate displacement, and constant load protection. The control modes can be smoothly switched between. Real time display of force displacement curve during the experiment, automatic calculation of key indicators such as anchoring efficiency coefficient and total strain, and automatic generation of testing reports that meet standard requirements. No manual intervention is required throughout the process, and the data is stable and reliable.
3. 10000kN ultra large tonnage, fully rigid
The host adopts a four column horizontal frame structure, and the key load-bearing components are made of integral cast steel technology. After finite element analysis optimization, it is ensured that the deformation of the frame is extremely small under the ultimate load of 10000kN, and the test data is true and reliable. The equipment is equipped with a front card jack and a dedicated anchor fixture, making it easy to clamp and accurately aligning the sample.
4. Multiple safety protections ensure worry free testing of thousands of tons with peace of mind
Once a large tonnage test specimen fractures, a huge amount of energy is released. The equipment is equipped with high-strength safety protection sand boxes and protective nets, effectively preventing steel strand breakage and splashing. Simultaneously equipped with multiple safety mechanisms such as overload protection, oil temperature protection, piston limit protection, emergency stop button, etc., to ensure the safety of operators and equipment.
5. Measurement level accuracy, authoritative and trustworthy data
The accuracy of the test force indication is better than ± 1%, with a resolution of 0.001mm. The equipment undergoes strict calibration before leaving the factory and can provide a 0.5 level accuracy configuration according to customer needs, meeting the strict requirements of national metrology institutions and third-party testing centers.
The Xinguang 1000 ton static load anchoring testing machine fully complies with the following national standards and industry specifications:
-GB/T 14370-2015 "Anchors, clamps, and connectors for prestressing tendons"
-JT/T 329-2010 "Anchors, Fixtures, and Connectors for Prestressed Steel Strands in Highway Bridges"
-TB/T 3193-2016 Technical Conditions for Anchors, Fixtures and Connectors for Prestressed Reinforcement in Railway Engineering
-GB/T 2611-2007 General Technical Requirements for Testing Machines
