Special Equipment

Standard Penetration Test Equipment

SPT involves driving a standard thick-walled sample tube into the ground at the bottom of a bore hole by blows from a slide hammer with standard weight and falling distance. The sample tube is driven 150 mm into the ground and then the number of blows needed for the tube to penetrate each 150 mm (6 in) up to a depth of 450 mm (18 in) is recorded. The sum of the number of blows required for the second and third 6 in. of penetration is reported as SPT blow count value, commonly termed  “standard penetration resistance” or the “N-value”.

Compression Testing Machine

Compression Testing Machine has been designed to meet the need of a simple, economic and reliable means to test concrete for its compressive strength. The load is displayed simultaneously on the Digital Load Indicator which incorporates a 4-Digits display calibrated in Kilo Newton (KN), preset to maximum load capacity and also on Bourdon tube type Load Gauge with a maximum load pointer. The Indicators are fitted with micro switches to switch-off the motor when the load approaches the maximum capacity of the gauge, avoiding any over loading. Relays are incorporated so that the motor does not restart on its own after a power breakdown. The electrically operated pumping units are provided with a control knob to adjust the pace rate which can be effectively controlled by an experienced operator during the course of testing, by observing the progress of the Digital Indicator readings or the Load Gauge readings. The electrically operated pumping units are also fitted with hand operated pump.

California Bearing Ratio [CBR] Test Machines

The California Bearing Ratio (CBR) Test is a measure of the strength of subgrade soil and highway sub base and subgrade via a penetration test. This machine includes a load ring and dial gauge and is used to measure force and piston travel, two travel speeds 1mm/min & 4mm/min and 50 kN capacity.

Test Features : CBR method adapts quickly to airfield pavement design for immediate use in comparison to any other method. It allows testing soil using simple, portable equipment. CBR Test can be conducted on field or in the laboratory. It tests the design, construction control as well as evaluation of existing construction. The Test is primarily intended for sub-grades but can also be used for wide range of different materials.

Los Angeles Abrasion Machine

The Los Angeles Abrasion Machine is used to measure the degradation of mineral aggregate of standard gradings resulting from a combination of actions including abrasion or attrition, impact and grinding in a rotating steel drum containing a specified number of steel spheres. The test is widely used as an indicator of the relative quality of various sources of aggregates having similar mineral compositions. Humboldt’s design follows the ASTM-preferred design and features a welded, structural-steel frame, fabricated .5″-thick (913mm) abrasion-resistant steel drum, a removable shelf, bolted to the drum and a balanced drum assembly for easy rotation by hand.

Ductility Testing Machine

The UTAS-0400 Ductility Testing Machine is used to determine the ductility of bituminous materials in a briquette mould by measuring the breaking elongation at a constant speed of 50 mm/min. It is designed to test 4 specimens simultaneously. The Internal tank is made of stainless steel. The bath is fitted with an immersion heater in order to obtain (in normal conditions) the 25°C test temperature. Each machine comprises speed control and water circulator to maintain the homogenous water temperature.

Tilting Flume

Tilting Flume is designed to conduct various experiments in various bed slopes both  upstream and downstream. The flume has a Perspex window to visualize the flow over models fixed in flume. The flume is provided with gates on both upstream & downstream side to control the flow. Students can thus conduct the experiments and also visualize the flow.  Various experiments like open channel flow study, specific energy curve, hydraulic jump, calibration of wires, notches and venturi flume can be conducted.

Total Station

Total Station is designed to measure slant distances, horizontal and vertical angles and elevations in topographic and geodetic works, tachometric surveys, as well as for solution of application geodetic tasks. The measurement results can be recorded into the internal memory and transferred to a personal computer interface. The basic properties are unsurpassed range, speed and accuracy of measurements. Total stations are developed in view of the maximal convenience of work of the user.

GPS

GPS satellites circle the Earth twice a day in a precise orbit. Each satellite transmits unique signals and orbital parameters that allow GPS devices to decode and compute the precise location of the satellite. GPS receivers use this information and trilateration to calculate a user’s exact location. Essentially, the GPS receiver measures the distance to each satellite by the amount of time it takes to receive a transmitted signal. With distance measurements from a few more satellites, the receiver can determine a user’s position and display it electronically to measure your running route, map a golf course, find a way home or adventure anywhere.

Electronic Theodolite

The series of Electronic Theodolite adopts the photoelectric incremental angle measuring system. They integrate optical, mechanical, electronic and computer technologies and realize a variety of functions including angle measurement, display and storage. They can also display horizontal and vertical angles and realize conversion from vertical angle to gradient and compensation of vertical angle. The precision of angle measurement is 5″. This series of Electronic Theodolite finds wide applications in the Grade III and Grade IV triangle control measurement in national and urban projects, including engineering measurement in railway, highway, bridge, water conservancy, mining projects, etc. It can be also used in various engineering in construction, erection of large equipment & land register, topographic survey and various kinds of engineering.
