LBTBP-1 Microcomputer-Controlled Tensile Strength Tester for Slope Flexible Protection Mesh

The slope flexible protective net system puncture‑resistance testing machine is used for evaluating the tensile strength of active and passive protective nets and flexible grid nets on highway slopes. It measures the local soil‑rock mass displacement capacity of slope‑protective nets, assesses their ability to prevent and delay slope collapses, evaluates their capacity to intercept falling rocks, windblown sand, and flying debris, and verifies their resistance to destructive forces such as turbulent flows, snow avalanches, bank erosion, and falling objects from waterfalls. The puncture‑resistance test for slope‑protective net panels is conducted in accordance with the specific test requirements of the JT/T 1328 standard.

LBTBP-1 Microcomputer-Controlled Tensile Strength Tester for Slope Flexible Protection Mesh

Description

Product Introduction:

The slope flexible protective net system puncture‑resistance testing machine is used for evaluating the tensile strength of active and passive protective nets and flexible grid nets on highway slopes. It measures the local soil‑rock mass displacement capacity of slope‑protective nets, assesses their ability to prevent or delay slope failures, evaluates their capability to intercept falling rocks, windblown sand, and flying debris, and determines their resistance to destructive forces such as turbulent flows, snow avalanches, bank erosion, and falling objects from waterfalls. The puncture‑resistance test of slope‑protective net panels is conducted in accordance with the specific test requirements of the JT/T 1328 standard.

Experimental procedure:

1. The specific experimental procedure was carried out in strict accordance with the requirements of standard JT1328. The tests were conducted under ambient room‑temperature conditions (10°C to 35°C) and complied with the provisions of GB/T 228.1.

2. Mount the specimen within the fixed frame, ensuring it remains above the impact‑top device. Verify that the geometric center of the specimen aligns with the geometric center of the impact‑top device; the width of one pair of tensioning devices on two opposite sides shall be symmetrical about the frame’s central axis. Secure the mesh at all four edges of the specimen to the corresponding edges of the fixed frame using shackles, link rods, wire ropes, or other connectors that match the structural characteristics of the test specimen. Prior to the start of the test, these connectors must not compromise the specimen’s inherent planar integrity.

3. Prior to the start of the test, the specimen shall be tensioned using the connectors, with its central deflection kept at no more than 20% of the specimen’s minimum dimension, and positioned as close as possible to the reference plane. During the test, continuous measurements and recordings shall be taken of the load applied by the loading apparatus, the natural sagging deflection of the metal mesh after installation, the tensile force of the metal mesh, and the puncture resistance.

4. In addition to ring‑type nets, wire‑rope nets, square meshes, grating nets, and double‑twisted hexagonal nets, impact‑resistance tests can be conducted on all these metal mesh types; the specific test procedures must comply with the technical requirements of their respective support systems.

Equipment Features:

1. The structure features a highly rigid frame, consisting of an upper crossbeam, a base, and vertical columns that form a closed load-bearing framework. Measurement of the test force is performed by a high-precision sensor and an electrical measurement and control system.

2. This testing machine employs a microcomputer-controlled, high-precision electro-hydraulic servo valve, with adjustable speed and customizable load settings.

3. All experimental operations are performed using a CRT display and controlled via the computer keyboard and mouse. The computer screen shows various test curves—such as force–time, force–displacement, and displacement–time—as well as the testing machine’s operating status. The scale of the curve axes can be adjusted according to the actual test data. Multiple test curves can be superimposed for comparison and exported for printing.

4. A robust, in-house experimental database has been developed, with experimental data managed in a database format for easy querying and maintenance. Experimental data can be saved, queried, and retrieved at any time, and various report formats can be generated and printed (with options to export reports in Excel or Word format).

5. The software system supports three-tier user management, ensuring security, convenience, and efficiency. It also enables data transmission and conversion between the user’s local area network and the Internet.

6. Fully automatic control, with automatic acquisition of test force and loading rate, enabling compression testing of rainwater collection modules of various specifications.

7. Safety protection: Equipped with automatic overload protection, overcurrent protection, overvoltage protection, overspeed protection, and other functions.
