Drilling
The objective of drilling work is to collect soil sample for testing engineering design and construction. This is the most effective method to evaluate the soil stratum in the construction site. Soil samples are then taken to provide for the determination of soil characteristics in the laboratory. Nowadays, this method is very popular in construction in Vietnam and over the world as well. Having about 10 drilling rigs together with skilled human resources, PortcoastGeo always satisfies the Client’s demands about schedule and also as the harshness of weather condition.
The 20HP drilling rig capacity is enough to make a borehole to 100m depth into soil or rock. The hole is made by rotary method combined with circulatory solution to lift the drilling mud upward. Some in-situ tests are also performed inside the drilled borehole such as: Standard Penetration Test (SPT), Field Vane Shear Test (FVST), Pressuremeter (PMT) and other tests. Besides, the drilled borehole is also used to install geotechnical instrumentations.

Field Vane Shear Test The field vane shear test determines the undrained shear strength of clayey soils at site. This test is done in both casing and borehole. When the vane reaches the desired depth, push the vane rods downward direction about 3 times vane diameter from the borehole bottom then rotate the gauge to record moment value. The expected result is the undrained shear strength at the depth. The field vane shear test is suitable for very soft to medium stiff clayey soils. The vane size is replaced for the proper material. 04 field vane machines doing well and a hydraulic Jack of 15 tons operated to push the casing to the required depth allow the test done quickly.

Piezocone Penetration Test The Piezocone Penetration Test is a versatile equipment and provide fast in-situ results. Based on recorded data, the soil strata are determined faster than other equipments. Data recorded by sounding transfer from memo-cone to the dataloger on surface. The inclinometer sensor is attached in the memo-cone to control inclination during penetration. Soil parameters are recorded such as: cone resistance (qc), sleeve friction (fs) …This equipment can also be performed pore water pressure dissipation test at the field – an important soil parameter in term of calculation the horizontal consolidation coefficient. Having 04 memo-cones, 03 dataloger both C-Mon and PC-Mon and 4 hydraulic jacks from 10 to 20 tons, Portcoast-Geo is proud of being as a leading company in this kind of test and always meet Client’s demand.

Pile Driving Analyzer (PDA) The PDA uses signals from reusable sensors to collect data. It consist of 2 Accelerometers and 2 strain gages. When a hammer or weight strikes top of pile, the compressive stress wave travel down its shaft and reflect up. Soil resistance forces along the shaft and at the toe cause wave reflection and are felt at the top of the pile. The measured force and velocity near pile top thus provides necessary and sufficient information to estimate soil resistance and its distribution. The Pile Driving analyzer technology applies dynamic measurements to solve pilling problems. Force and acceleration measurements taken near the top of a pile during impact provide the necessary information for determining: + Activated bearing capactity + Hammer performance + Maximum driving stresses + Pile or Shaft Integrity PDA test can be applied on all types of pile, such as pre-cast concrete pile, in-cast placed pile, steel pile, timber pile, composite pile… PDA Testing is a quick, low cost and very reliable tool. You save time and money. You gain quality assurance.

The monitoring system for soil improvement stage Inclinometer system is used to monitor lateral movement of slope embankment during construction stage or slope protection. The inclinometer probe, datalog box and casing were manufactured by Geokon Co., (USA). There are 02 types of conventional Piezometer: vibrating-wire piezometer and standpipe piezometer. Magnetic extensometer is utilized to measure settlement of soft soil under the influence of loading during soil improvement or construction stage. The magnetic extensometer consists of components spider magnet, plate magnet, datum magnet, telescoping coupling, access tube and cable reel with audible Observation well is used for monitoring ground water level in a soil layer of stratum.

Pressuremeter Test (PMT) The Pressuremeter Test (PMT) provides a tress-strain response of the insitu soil. A deformation modulus called the pressuremeter modulus (Ep) and a limit pressure (PL) can be obtained from the stress-strain relationship for geotechnical analysis and foundation design. The pressuremeter test is performed by applying pressure to the sidewalls of a borehole. The pressuremeter consists of two parts, the read-out unit, which rests on ground surface, and the probe that inserted into the borehole. The probe consists of three independent cells, a measuring cell and two guard cells. Once the probe is at the test depth, the guard cells are inflated to brace the probe in place. Then the measuring cell is pressurized with water, inflating its flexible rubber bladder, which exerts a pressure on the borehole walls. As the pressure in the measuring cell increases, the borehole deforms. The pressure within the measuring cell is held constant for approximately 60 seconds, and the increase in volume required maintaining the constant pressure is recorded. A load-deformation diagram is recorded for each test run.

Laboratory testing for soil Physical Testing Grain size distribution analysis: The test is conducted in two stages: sieve analysis for coarse-grained soils (>0.075mm) and hydrometer analysis for fine-grained soils (< 0.075mm). The results are presented by a grain size distribution curve which is combined as the percentage of sample smaller than, by weight, versus the log of the particle diameter. The curve provides the parameters about effective diameter (D60 & D10) and coefficient of uniformity (Cu). Tests were performed in accordance with ASTM D422. Atterberg limits test: Atterberg limit test aimed to determine liquid limit (LL) and plastic limit (PL) which are very important indices used for classification of cohesive soil. The testing equipments are manufactured by HUMBOLDT – USA and procedures are according to ASTM, BS.
