I. Overview

GZQ-1 automatic pneumatic consolidation instrument is used to measure the compressive properties of soil under different loads and confinement conditions. The whole system consists of consolidation instrument, pneumatic controller, multi-channel communication converter, data acquisition system, Normal slow consolidation test and rapid consolidation test can be carried out to determine the pre-consolidation pressure and consolidation coefficient. The system has the characteristics of stable and reliable air pressure control, low noise, separate control of consolidation pressure, convenient software system installation, light weight, small footprint, and good software interface. In particular, the consolidation pressure can be set separately, which can greatly improve the flexibility of the instrument, shorten the test cycle, and have a high performance-price ratio. Meet SL 237-1999 "Geotechnical Test Regulations", JTG E40-2007 "Highway Geotechnical Test Regulations", TB10102-2010 "Geotechnical Test Regulations for Railway Engineering", GB/T50123-2019 "Geotechnical Test Method Standard".

2. Main use

It is used to measure the compressive properties of soil under different loads and confinement conditions. The whole system consists of a consolidation instrument, a pressure controller, a multiplex communication converter and a data acquisition system. The instrument can perform normal slow consolidation test and rapid consolidation test, and measure the pre-consolidation pressure and consolidation coefficient. The system has the characteristics of stable and reliable air pressure control, low noise, separate control of consolidation pressure, and convenient software system installation.

3. Main technical parameters

6. Converter channel: 1-16 (the number of channels can be arbitrarily configured according to customer needs)

7. Material: The shell of the double main engine is made of all-steel material and the surface is sprayed with plastic. The cylinder block is made of aluminum alloy die-casting in one-time molding.

8. Consolidation container: 16 sets (stainless steel material is corrosion-resistant and watertight)

4. Instrument configuration

Special Note:

    The standard configuration of the fully automatic air pressure consolidation instrument launched by our company is 16 channels (ie: 16 consolidation vessels), and the number of channels (the number of consolidation vessels) can also be configured according to customer needs. 24 channels, 32 channels, 48 channels or For any number of channels, one fully automatic air pressure loading and unloading controller is recommended to have a maximum configuration of no more than 48 channels. Welcome new and old customers to inquire.
