Product Description

Complete Geotechnical Testing Solution with Intelligent Multi-Channel Consolidation System

This series of geotechnical testing equipment includes fully automatic pneumatic consolidation apparatus, lever-type consolidation instruments, multi-unit consolidation systems, and supporting testing devices, providing a complete solution for soil mechanics testing. It is widely used in highway engineering, foundation projects, research institutions, and third-party laboratories.

The core product, the GZQ series 16-channel fully automatic pneumatic consolidation apparatus (low/medium/high pressure), adopts pneumatic loading and intelligent control technology, supporting up to 16 simultaneous tests with centralized control and data acquisition via RS485 communication. It enables accurate analysis of soil deformation, void ratio, and time-dependent behavior under different pressure conditions, allowing calculation of key parameters such as compression index, rebound index, compression modulus, and consolidation coefficient.

The system complies with JTG 3430-2020 Highway Geotechnical Test Procedures and GB/T 50123-2019 Standard for Soil Test Methods, and features high-precision pressure control (up to 3200 kPa), 0.01 mm settlement measurement accuracy, and a stable pneumatic control system suitable for various sample sizes and multi-stage loading tests.

GZQ Series Fully Automatic Pneumatic Consolidation Apparatus (16-Channel: Low / Medium / High Pressure)
The GZQ series fully automatic pneumatic consolidation apparatus is designed for advanced soil consolidation testing, replacing traditional lever-type systems with intelligent pneumatic loading and multi-channel automation. Supporting up to 16 simultaneous test channels, the system enables precise measurement of soil deformation under varying pressure conditions, as well as relationships between void ratio, pressure, and time.

With high-accuracy pressure control (up to 3200 kPa for high-pressure models) and axial deformation measurement accuracy of 0.01 mm, the system ensures reliable and repeatable results. The integrated RS485 communication allows centralized control and real-time data acquisition, significantly improving testing efficiency.

This equipment complies with JTG 3430-2020 Highway Geotechnical Test Procedures and GB/T 50123-2019 Standard for Soil Test Methods, and is ideal for geotechnical laboratories, infrastructure projects, and research institutions.

 
WG Series Lever-Type Consolidation Apparatus (Single / Double / Triple Unit)
The WG series lever-type consolidation apparatus adopts a traditional mechanical loading structure, providing a cost-effective and reliable solution for routine soil compression testing. Available in single, double, and triple-unit configurations with low, medium, and high-pressure options, it is suitable for determining the relationship between soil deformation and applied pressure.

With stable lever ratios and flexible loading ranges, the WG series allows accurate calculation of compression index, rebound index, and consolidation coefficient. Its simple structure, ease of operation, and low maintenance requirements make it particularly suitable for teaching laboratories and standard engineering testing applications.

YYW-2 Strain-Controlled Unconfined Compression Tester
The YYW-2 tester is used to determine the unconfined compressive strength of saturated soft clay under axial loading without lateral restraint. It supports both manual and motorized operation, ensuring controlled loading rates and consistent test conditions.
With a maximum load capacity of 5 kN and precise displacement control, this instrument provides reliable strength parameters for soil stability analysis and foundation design.
 
GJY Series KO Consolidation Apparatus
The GJY KO consolidation apparatus is specifically designed to determine the coefficient of earth pressure at rest (K0). It enables accurate measurement of axial load and lateral pressure on soil samples under controlled conditions.
Compact in size and easy to operate, this equipment is suitable for laboratory environments requiring precise evaluation of in-situ stress conditions in soil mechanics research.
 
TYC-1 Pore Pressure Measuring Instrument
The TYC-1 pore pressure instrument is a digital pressure measurement device used for monitoring pore water pressure in geotechnical tests such as triaxial testing and KO consolidation tests.
It features a clear digital display, high sensitivity, and stable performance, with a measurement range up to 999.9 kPa and accuracy up to 0.1 kPa. The device is also applicable for measuring pressure in non-corrosive gases and liquids.
 
TST-70 Soil Permeability Apparatus
The TST-70 soil permeability apparatus is designed for constant head permeability testing of sandy soils and non-cohesive soils containing small amounts of gravel. Built based on standardized methods, it allows accurate determination of soil permeability characteristics.
The system includes a permeation cylinder, measuring tubes, and compaction components, ensuring stable water flow and precise readings. It is widely used in civil engineering, hydraulic projects, and soil research applications.
