Heico's Hydraulic Consolidometers areavailable for conducting consolidation testson smaller to larger sized soil specimensunder saturated condition with the applica-tion of back pressure. A check on thedegree of saturation can be performed. Thepore pressure dissipation during consolida-tion can be measured under various simu-lated drainage conditions namely, one-way,two-way, radial in-wards or radial out-wards. The consolidation pressure can beapplied through a flexible diaphragm tosimulate field consolidation under uniformpressure or under uniform deformation.

Deformations volume changes and pres-sures are measured with a great degree ofprecision. The hydraulic Consolidometeropens up a vast research potential of theo-retical and applied nature on offshore andonshore soft to stiffer clays.

Consolidation Cell

Heico hydraulic consolidation cells come in differ-ent models for small to large diameters of sam-ples. Since the loading is through pneumatics,drainage can be precisely controlled.

Various methods of drainage and loading con-ditions can be applied to the specimen.Basically cells of three different sizes are avail-able. Each type can with stand a pressure of10 bars. No-volume change valves are fixed attop plate, bottom plate and in the middle fordifferent combination of test requirements.

Pore Pressure Measuring DeviceThe pore water pressure apparatus is inprinciple a 'U' tube filled with mercury. Onebranch of 'U' is connected through a coiledcopper tube to the base of the test speci-men, the other end is coupled to a closedsystem having a screw control hand pump,pressure gauge and a manometer. Byincreasing or decreasing the back pressureby the screw control, the mercury level canbe maintained at a 'null point'. The pressurerequired to maintain the mercury at its nullpoint is thus equal to pore pressure at thebase of the soil specimen. Based on Bishopand Hankel design, the pore pressure unithas a manifold null indicator in which addi-tional air vents and mercury traps havebeen provided for quick and easy de-airingbefore test.

The volume change gauges are designed to

measure changes in volume of specimen,

measured in terms of the change in the vol-

ume of the cell, during a triaxial shear test.

The apparatus consists of an outer acrylic

tube and an inner graduated glass burette

held between two aluminum blocks.

Manifolds are provided to enable water,

either to pass through the tubes during

measurements or to go direct to the cell

when no measurements are required. The

indicator is coloured paraffin (not supplied

with the unit). The volume changes are

measured by the downward movement of

paraffin/water inter-face in tube burette.

In the twin burette gauges the manifolds

allows the reversal of flow of water, this

enabling continuous measurements when

testing large diameter samples. The gauges

are designed for a working pressure of

1000kpa.

Soil exploration at a proposed site is a pre-requisite for taking up the design of anystructure so that it is safe as well as eco-nomical. Necessary information regardingthe soil conditions, geotechnical propertiesof soil at site and its performance underproposed structural loads should beassessed before design of any structure.

Soil exploration can be grouped into twoparts viz. Preliminary exploration anddetailed investigations. 'HEICO' offers toolsand instruments for both shallow and deepsoil explorations.

Useful for shallow sub-soil exploration, theaugers are used in cohesive and semi-cohe-sive soils for collection of disturbed soilsamples or for advancing bore holes for col-lection of undisturbed soil samples atdesired depths. Fabricated from hardenedsteel the augers can withstand prolongeduse in all type of soil.

Penetration Tests have been found very use-ful and economical, for sub-soil exploration.The correlation of these tests with variousother standard tests and soil parameterslike cohesion and angle of friction havemade these tests much more useful in eval-uation of soil strength in-situ.

The tests have gained importance particu-larly in soils where undisturbed sampling isnot possible either due to its high moisturecontent or non-cohesive nature. IS : 4968specifies three different methods for sub-surface sounding of soils.

Part 1. Dynamic method using 50 mm conewithout bentonite slurry.

Part II Dynamic method using 62.5 mmcone with bentonite slurry.

Part III. Static cone penetration test.

The standard penetration test using a splitspoon sampler is covered separately in IS :2131.

�� HS34.60Dynamic Cone Penetration TestApparatus

(50 mm cone without bentonite slurry)

The apparatus helps for determining rela-tive resistance of soil strata at differentdepths to penetration of 50 mm dia, 60o

cone under standard driving energy perstroke. The resistance offered 'Ncd' to pen-etration of cone in terms of number ofblows of 65 kg hammer falling freelythrough a height of 75 cm per 30 cm pene-tration is correlated with bearingcapacity of cohesionless soils and also withthe load carrying capacity of piles. Bore holeis not required for this test.

�� HS34.65Dynamic Cone Penetration TestApparatus (62.5 mm cone withoutbentonite slurry)

In this test a modified version of the 60o

cone is used wherein arrangements for cir-culating bentonite slurry is additionally pro-vided. As in the earlier case the cone herealso is directly driven into the ground andthe bentonite slurry reduces the skin frictionof the driving rods.

The resistance of the cone per 30 cm ofpenetration in this case is designated asNCbr.

PENETRATION TEST

DYNAMIC TEST

S-53

Static cone penetration test is international-ly recognized as a standard field test to col-lect data about bearing capacity and fric-tional resistance of soil.

The equipment meets the essential require-ments of IS:4968 (Part - III) the probingpart consists of a cone which has an apexangle of 600 and an overall base diameterof 35.7 mm equivalent to area of 10 cm2.

The cone is connected with sounding rodswhich are protected by mantle tubes. Theassembly of sounding rod and mantle tubeis pushed into the soil, by means of amechanical rack jack or by an engine drivenhydraulic pumping unit and ram. Basicallythe test procedure consists of first pushingthe cone alone, then the cone and the fric-tion jacket and finally the whole assemblyin sequence through specified depth andnoting the resistance in the first two cases,limited to the designed capacity of the unit.The readings are taken for every 20 cm ofpenetration, and thus continuous data ofend bearing and frictional resistance of soilis recorded. The results are correlated withbearing capacity and settlement of shallowfoundation and piles.

Static Cone Test is unsuitable for gravellysoils. The Static Cone resistance is correlat-ed with the 'N' value as obtained from stan-dard penetration test, thus increasing theutility of the test.

The Insitu Vane Shear Test gives the in placeshearing resistance of soft, saturated clayswhich are sensitive and are susceptible tosampling disturbances. The test giveundrained shear strength of soil, along acylindrical surface without change in vol-ume or soil structure.

The test consists of pushing a vane withfour blades into soil and rotating it till thecylindrical surface in soil fails in shear. Thetorque or turning moment required to causethis failure is measured on a Torque Meter.

The maximum moment of the total shearmobilized about the axis of rotation is equalto the applied torque. The unit shear resist-ance of the cylindrical surface can thus becomputed.

Water Stills are used to prepare distilledwater for specimen preparation and labora-tory testing.

The still is an essential part of equipment inmodern material testing laboratories. Inoperation the water is heated gently andconverted to steam by keeping it boilingat a slow rate. The steam is condensed inan in-built condenser and the distillate col-lected in a receiver. This is free from allimputerities and gases. Copper, brass,bronze and tin are used in the fabricationof the stills. The surfaces coming in contactwith water are heavily tinned which pre-vents metallic contamination. A water inletvalve is a part of the still for connecting toa tap. An overflow is also provided to main-tain the water at proper level. Two sizes ofstill are manufactured by us one having twolitre per hour capacity and the other fourlitre per hour capacity.

Introduction

Flat jacks are used for the determination ofIn-situ rock stress by relief technique. Thetest method consists of cutting a thin slot

into the surface by drilling a series of over-lapping holes. The process relieves the rocksurface of the stress which originally existedacross it. This is measured between twopoints across the slot fixed in the rock priorto cutting the slot. This convergence occur-ring is then neutralized by inflating a flatjack fixed in the slot and the cancellationpressure is noted. Assuming that the rockmass is elastic within range of workingstress, this cancellation pressure is taken asvery nearly equal to the pressure that exist-ed in the rock normal to the plane of slotbefore the slot was cut. HEICO flat jackequipment meets the essential require-ments of IS: 7292-1974.

Since recent studies have shown that uni-formly distributed entrained air improvesthe properties of concrete in many waysand also considerably improves the worka-bility of fresh concrete, their use in all majorconstruction works involving mass concret-ing is now being widely adopted. Thoughentrainment of correct proportion of airgives the concrete good weathering resist-ance, too much of it affects the strengthwhile too little causes rapid deterioration byweathering. As such, control of the air con-tent in fresh concrete to optimum propor-tion before its placement through regulartest checks by right type of equipment isvery important.

HEICO offers two different models of airentrainment meters; that is type A and typeB for estimation of air content of concretemixes having different maximum sizedaggregates. They are pressure type instru-ments and use the principle of Boyle's lawfor indication of air content in the concrete.

These Jacks are similar to remote controlledhydraulic jacks described earlier, but theirrams are threaded and provided with a locknut. After lifting the load the lock nut is soadjusted that it rests firmly on the top of thecylinder and the whole load is taken up bythe cylinder, thus eliminating any possibilityof its coming down in case of accidentalfailure of the hydraulic mechanism or sealof the jack.

This also enables the holding up the loadfor long duration without straining the

hydraulic system and ensures the safety ofworkers working underneath supportedheavy structures like, heavy beams, launch-ing girders of bridges, supported structuresin tunnels etc.
