The crawler-truck has been designed to execute soil mechanical research based on static Cone Penetration Testing CPT techniques in an efficient manner. The objective of the plate loading test is the determination of the vertical deformation and strength properties of soil and in-situ rock mass by recording the load and the corresponding settlement when a rigid plate modelling a foundation is loaded onto the ground. This was investigated by Dobie a and the plot of local friction versus peak vane shear strength is shown on Figure 8 for the Singapore marine clay upper, intermediate and lower.

cone penetration testing equipment available in Singapore
One common test method used to investigate these deposits is the cone penetration test CPT , which Geotextiles are porous, flexible, man-made fabrics which act to reinforce and increase the stability of structures such as earth fills. The cone penetrometer is pushed into the soil at a constant rate of penetration. By Pagani Geotechnical Equipment s. Market focus Globally various continents Internationally various countries Nationally across the country Regionally various states or provinces Locally one state or province. The determination of in-situ permeability tests in borehole involves the application of a hydraulic pressure in the borehole different from that in the ground, and the measurement of the flow due to the difference.
The plate loading test is carried out on a thoroughly levelled and undisturbed surface either at ground level or on the bottom of an excavation at a certain depth of the bottom of an exploration shaft or gallery. Report for geotechnical, underground conditions and environmental reports are produced after performing in-situ testing and in-situ monitoring. The test is carried out a using geonor type self penetrating vane shear equipment. Based on density contracts that generally exist between geological materials, the refraction method is utilized to provide detailed information on the distribution and thickness of subsurface layers with characteristic seismic velocities. By means of the penetrometer pusher, installed in the centre of gravity of the CPT The deployment system includes a self-tensioning umbilical winch to accommodate power and signal telemetry.
Once at a predetermined depth the membrane is expanded under pressure and readings of pressure and expansion are recorded until a maximum expansion for the device is reached. The electrodes are used to send electricity current into the soil and measure the voltage between them. Seismic test are carried out to measure shear S wave and compression wave P wave velocities in soils. Load to be measured on the cone of the CPT In order to appreciate better a typical CPT profile in the upper marine clay, Figure 4 shows a 20m profile, taken from Dobie a. Technical capabilities of the site investigation team include: Continuous readings of cone resistance qc , local friction fs , pore water pressure u2 and friction ratio Rf are recorded during the test.
