LTB-8 Rock Mass Rigid Pressure Plate Testing Instrument

A rock mass pressure plate is an instrument used to assess the deformation characteristics of rock masses. It operates by simulating the loading conditions experienced by foundations; by applying a load and measuring the resulting deformation, it enables the determination of parameters such as the rock mass’s modulus of deformation.

LTB-8 Rock Mass Rigid Pressure Plate Testing Instrument

Description

Product Introduction:

In accordance with the standard SL/T 264-2020, “Test Procedures for Rock in Hydraulic and Hydroelectric Engineering,” the rock mass pressure plate is a device used to evaluate the deformation characteristics of rock masses. It operates by simulating the loading conditions experienced by foundations: a load is applied, and the resulting deformation of the rock mass is measured, enabling the determination of parameters such as the deformation modulus. Pressure‑plate tests are typically conducted in underground tunnels, and the testing apparatus comprises a pressure plate, a jack, a load‑transfer column, and a displacement gauge. The pressure plate must possess sufficient stiffness, and its dimensions should match the area subjected to the applied load.

Technical Specifications:

Normal maximum pressure 1000 kN

Maximum normal piston stroke: 50 mm

Pressure plate area: 2500 cm²

Measurement system, range 0–50 mm, with 8 dial indicators.

100-ton force sensor

Load-bearing columns: 5, each one meter long.

One set of electro-hydraulic pump station
