MACHINERY

HYDRAULIC PILING RIG AUGER

LINER BENTONITE TANK TREMIE PIPE

TRANSIT MIXERS BATCHING PLANT

SOME OTHER MACHINERIES:-

VERTICAL PUMP  DEWATERING PUMP (VERTICAL)  D.G. SET  BAR CUTTING MACHINE  SOUNDING MACHINE

 

METHODOLOGY

1)PILE LOCATION:» THE WORKING PILES SHALL BE INSTALLED AT

LOCATIONS AS PER DRAWING. 

2)CASING DRAWING:» LINER OF 1m DIA WITH 8mm/6mm THICK WILL BE PLACED

IN THE POSITION AND PUSHED DOWN THE HAMMER ,SAME WILL BE CHECKED FOR VERTICALITY AND BORING WILL BE CONTINUED.

3)BENTONITE FOR PILING:» BENTONITE SHOULD BE USED IN THE PILING WORKS

CONFORMING TO THE FOLLOWING SPECIFICATIONS. 

» DENSITY OF MUD WILL NOT EXCEED:1.05 gm/cc-1.12 gm/cc

» MARSH CONE VISCOSITY:30-40 sec» SWELLING INDEX:AS PER IS 6186-1986» PH VALUE:9.5-11.50» SAND CONTENT>.075mm: NOT MORE THAN 1%» LIQUID LIMIT:NOT LESS THAN 400%

» THE BENTONITE REQUIRED FOR PILING WILL BE MIXED 24 HRS IN ADVANCE AND STORED IN THE BENTONITE TANKS.

» THE SPECIFIC GRAVITY OF BENTONITE IS LESS THAN 1.2g/cc AT THE BOTTOM OF THE BORE BEFORE COMMENCING CONCRETING OPERATION. 

4)BORING:» FOR BORING OF THE PILE SOIL AUGER AND BUCKET WILL BE USED.

5)REINFORCEMENT CAGE:

  a) FABRICATION:» REINFORCEMENT WILL BE CUT USING CUTTING MACHINES OR

MANUALLY AS REQUIRED. 

b)LOWERING OF CAGE:» THE APPROVED CAGE WILL BE LOWERED INTO THE BORE IN

SEGMENTS.CRANE OR HYDRA WILL BE USED TO HANDLE THE CAGE SEGMENTS.  

                     FABRICATION                                                                                       LOWERING OF CAGE

6)FLUSHING:» THE PRE ASSEMBLED TREMIE PIPES SHALL BE LOWERED IN THE

BORE HOLE KEEPING THE BOTTOM 300mm ABOVE THE TERMINATION LEVEL.FLUSHING OF THE BORE WILL BE DONE WITH BENTONITE PUMP ATTACHED WITH TREMIE PIPE AND TREMIE .

  7)CONCRETING:» THE REQUIRED GRADE OF CONCRETE WILL BE PRODUCED AS

PER THE APPROVED DESIGN MIX AT THE CENTRALIZED BATCHING PLANT AND TRANSPORTED BY TRANSIT MIXERS.

» ENSURING A SLUMP RANGE OF 150mm TO 200mm AT SITE. 

8) EXTRACTION OF TEMPORARY CASING:- ALL TEMPORARY CASINGS ARE TO BE EXTRACTED IMMEDIATELY AFTER COMPLETION OF CONCRETING.

»TEMPORARY BENCHMARK SURVEY

SITE:BARHAN,TUNDLA

ENGINEER:YASHPAL SINGH

A temporary benchmark in surveying is a control point that is set by a surveyor to base other points off of. They will assign it an elevation, and other points that are surveyed off of that point will have a relative elevation rather than an absolute elevation

» STEPS FOR LEVELLING THE STAFF:-

» FIND THE BENCH MARK.» PICK AN INITIAL PLACEMENT FOR 

TRIPOD AND LEVEL.» LEVEL THE INSTRUMENT ON TOP 

OF TRIPOD.» TAKE BACKSIGHT READING.» CALCULATE HEIGHT OF 

INSTRUMENT(HI).» NOW TAKE FORESIGHT READING.» CALCULATE  THE  ELEVATION OF 

GROUND AT SECOND LOCATION KNOWN AS A TBM.

PRESSURE ON FORMATION & SUB SOIL:

BALLAST 3 KG/SQ.CM (MAXIMUM)

SUB SOIL 1 KG/SQ.CM (MAXIMUM)

DESCRIPTION OF SOIL QUALITY CLASS:

SOIL QUALITY W.R.T FINE PARTICLE

SQ1  >50%

SQ2 12%-50%

SQ3 <12%

» Functions :» A blanket/sub-ballast layer fulfils following important functions :

Primary Function :» Stress Reduction Function

» Secondary Function :» i) Separation Function

» ii) Drainage Function

» iii) Prevention of Mud Pumping

»LABORATORY TESTSENGINEER:MUKESH KUMAR

»CONCRETE TESTSLUMP TEST

» Slump test is very common test for and it is very important for consistency of concrete. It is not a suitable for very wet or very dry concrete. It is used convenient a control test and it gives uniformanity concrete. From the batch to batch.

» APPRATUS»  1) Slump cone» 2) Tamping rod » Dimension of slump cone :-

Bottom diameter – 20 cm

Top diameter – 10 cm

Height – 30 cm

» 150 x 150MM Cube Moulds Test

Purpose The moulds are used for making of concrete cubes as per IS :516 – 1959 – Methods of tests for strength of concrete. Apparatus Wheel barrow, sampling scoop, trowel cube moulds of 15 x 15 x15 cm size and tamping bar 16 mm in diameter, 0.6 m long and bulleted point at the lower end.

»DIGITAL COMPRESSION TESTING MACHINE

The digital compression – testing machine is used to determine the compressive strength of hardened concrete specimens.

»AGGREGATE TEST

AGGREGATE IMPACT TEST

The Impact value test generally used as alternative to its crushing strength to know quality of aggregate. It is also useful for to know the quality of aggregate this test is apply only 10mm metal. So as to decide its suitability for use in the desired concrete mix.

» SIEVE ANALYSIS FOR FINE AGGREGATE

The sieves are used for the determination of particle size distribution of fine aggregate by sieving (As per IS 2386 part I – Methods of test for aggregates for concrete) 

» SIEVE ANALYSIS FOR COARSE AGGREGATE

CONCLUSIONIT WAS A WONDERFUL LEARING EXPERIENCE AT TATA ALDESA (JV),TUNDLA,FIROZABAD FOR FIVE WEEKS.I GAINED A LOT OF INSIGHT REGARDING ALMOST EVERY ASPECTS OF SITE.I WAS GIVEN EXPOSURE IN ALMOST ALL THE DEPARTMENTS AT THE SITE,BUT I WOULD LIKE TO HIGHTLIGHT THE AREAS OF SAFETY,QUALITY MANAGEMENT,MATERIAL MANAGEMENT ,FORMATION AND EXECUTION.

I HOPE THIS EXPERIENCE WILL SURELY HELP ME IN MY FUTURE AND ALSO IN SHAPING MY CAREER.
