• Pilling for bridges, buildings, railway tracks & jetties etc.
• Diameters of bored piles range from 0.6 meter to 2.0 m meters
• SRC able to construct pile with percussion, reverse rotary & straight rotary

PLATE LOAD TEST

• Plate Load Test is a field test
• Determine the ultimate bearing capacity of soil
• Determine the maximum settlement under a given load
• Provides data for use in the evaluation and design of rigid and flexible-type airport and highway pavements

PILE CAPPING

A reinforced concrete slab is cast over the tops of the pile or group of pile to form a single structural element

INSTRUEMENTATION

SRC provides a variety of Geotechnical instruments and their installation that can be suitable for monitoring the safety and stability of a variety of civil and mining structure including dams, barrages, tunnels, foundations, mine openings, piles, etc.

INSTALLATION OF DATA ACQUISITION SYSTEM

SRC offers the installation of Data Acquisition System to monitor the dams & barrages that includes components for data collection that is permanently installed, & programmed to operate without human intervention.

• Automated collection of data
• Transmission of data to a remote site
• Processing & Plotting of data

SRC systems can operate as stand-alone. Once programmed and powered, no human or computer interaction is required, although data are typically downloaded to a PC for further analysis. A telecommunications or hardwire link allows data to be monitored and graphed in your preferred location rather than the field. Data from a number of stations and from a number of applications can be monitored from a single laptop or desktop computer.

The low power drain typically allows our data acquisition systems to be powered by solar panels and batteries

INSTALLATION OF PIEZOMETER

SRC Provides and installs every type of piezometer in dams, barrages, tunnels, railway tracks and foundations etc. Piezometers measure pore-water pressure and ground water levels, providing information essential to:

• Understanding initial site conditions
• Determining safe rates for placement of fill
• Predicting slope stability
• Designing for lateral earth pressures
• Evaluating the effectiveness of drainage schemes
• Checking the performance of containment systems

INSTALLATION OF INCLINOMETER

Provides and installs Inclinometer which is helpful to get following information:

• Measurement of lateral earth movements which might occur in unstable slopes, landslides, dams and roadway embankments & landfills
• Measure the deflections in the wall of excavations, shafts, tunnels and in caissons pile and sheet pilling
• Measures differential settlement along the length of casing

INSTALLATION OF TILTMETER

• Tiltmeter is designed to measure tilt in structures such as buildings, dams & embankments
• Measurements related to stability of slopes, open pits and the walls of excavations
• Measurements of any tilting or differential settlements along embankments, railway tracks, road tracks, pipelines, tunnels, etc.
• Measure the horizontal deformation of retaining walls, sheet pilling etc.

INSTALLATION OF SOIL EXTENSOMETER

Soil Extensometer is designed to be installed, in series, to measure horizontal strain and settlements in earth fill or rock fill dams.

INSTALLATION OF HIGH SENSITIVITY SETTLEMENT SYSTEM

• It consists of a series of vessels containing liquid level
• Monitor the Differential settlement, or heave
• This system is particularly suitable for critical situations where high resolutions are required
• It will measure the Elevation changes of as little as ±0.02 mm is detectable

INSTALLATION OF EARTH PRESSURE CELLS

They are designed to measure total pressure in earth fills and embankments. A vibrating wire pressure transducer converts the pressure into an electrical signal which is transmitted to the readout location.

INSTALLATION OF PILE TIP PRESSURE CELL

• Pile Tip Pressure Cell is used to measure pile-tip loads in cast-in-place concrete piles (caissons)
• This cell is manufactured to be close to the diameter of the pile
• This cell is connected to the bottom of the reinforcement cage

INSTALLATION OF LOAD CELLS

• Load Cell is made from an annulus of high-strength steel or aluminum, with electrical resistance strain gages in a Wheatstone bridge configuration
• The load cell is designed primarily for use on tiebacks and rock-bolts
• It will be used during pile load tests and for monitoring loads in cross lot struts and tunnel supports, etc.
• The load cells are used in conjunction with a hydraulic jack and bearing plates.

INSTALLATION OF STRESSMETERS

• It can be installed in boreholes up to 100 feet deep
• It is used to measure compressive stress changes in rock, salt, concrete or ice
• The measurement of in situ stresses is important in the design of underground openings such as power houses, crushing stations, mines, tunnels and the like
• It is also useful for determining the inherent stability of pit slopes, foundation excavations, mine pillars and dam abutments

INSTALLATION OF INSTANTEL

• It is manufactured as a complete line of vibration and overpressure monitors
• Monitors for regulated vibration and overpressure control
