CONSTRUCTION ACTIVITY
CONSTRUCTION OF CIRCULAR RAMP
CONSTRUCTION OF CIRCULAR RAMP
• For vertical transportation of vehicles in multilevel, car parking, circular ramp has been proposed.
• Circular ramp is typical from first storey to fifth storey, For construction of ramp shuttering of ramp is very important, as compared to reinforcement and concreting .
• Total length of ramp 25 meter along center line, slope 1:10.
RAMP DETAILS
SHUTTERING OF CIRCULAR RAMP
• Stagging• Decking• Sheathing• Levelling• Fixing beam side • Supporting
STAGING
• Stagging is done by 1.5m vertical and grid of 1.25m x 1.8m.
• Stagging is done more or less radially out words
• Before staging marking by surveyors is given marking such as center point of the ramp and levels at two corner of column for approximate rough idea
DECKING• Decking of ramp refers to arrangement of ISMC100 and
aluminium secondary ISMC100 is placed over staging grid on u-head and locked with wooden wedges, ISMC is placed such that it radiates out words from the center.
• Since the level is changing along circular line, to facilitate that aluminium secondaries are kept over the channel such that they form a circular part and can be levelled easily, means the grid portion can be levelled easily.
• In case of outer portion where the distance between staging is large and secondary cannot comodate a connecting staging is done and secondaries are fined.
SHEATHING
• After staging is done the ramp is covered with ply such that circular shape is visible.
• Generally full ply are used, if full not possible then only ply is cut.
• The staging and decked secondary is covered with plywood of 12mm thick.
LEVELLING• Levelling of circular ramp is most important, circular ramp is levelled with
the help of automatic level and staff.• An auto level is installed at stable place from where the whole ramp is
visible.• Now the surveyor marks the radial lines on the plywood. The center length
of the ramp is 25m, it is divided in 25 equal parts of 1m and marking is done this is done with the help of total station.
• Now, inner length is 16615 hence inner radius is divided into 25 parts hence marking is done at 665mm by the carpenter. All three points are matched and 25 radial lines are marker on ramp.
• Now staff is held at all three points and with the help of auto level the ramp is level, the level is lowered or lifted by adjusting U-jack and base-plate.
• Similarly the staff is shifted to all radial lines and the procedure is repeated, it is very tedious process.
FIXING SIDES OF INVERTED BEAM
• After the sheathing and levelling of ramp is done, sides of the inverted beam along is fixed there are two inverted beam along inner and outer side of the ramp, for fixing of sides first of all two templates are made
• Inner radius 4700mm• Outermost radius :10400
SUPPORTING• For supporting of staging, all the staging are inter connected by
swivel coupler and ledger. It is important to tie staging internally because if one staging fails other supports it, since the staging are erected on sloping ground it is necessary to inter connect the staging. Also the side of the inverted beam are checked, also the gaps between the ply is filled with foam sheet and scaled with masking tape.
• The staging are interconnected with ledgers at 3 spots along all verticals and at top and bottom, also cross bracing with 6m pipe is also done.
• Supporting is very crucial and needs special attention by the engineer.
Reinforcement of ramp
• In case of circular ramp the main problem is of bending circular reinforcement for that
• when the ramp, sheating and levelling is done, filter takes a 16mm dia. Bars and place at in position and bend it with hand on side he does this for inner and outer beam. So he makes 6 such templates bars of 16mm
• Now he takes the bar to the bending machine and bends 25mm dia. Bars same as 16mm dis bars, bends are made generally at 300mm. That this dependent on expertise of the bender.
CONCRETING OF RAMP
• Grade : M30• Type: RMC• Mode of concreting : By pumping• Mode of vibration: 60 mm needle vibrator• Mode of curing: Ponding

CONSTRUCTION ACTIVITY
INSERT PLATE FOR CANOPY
INSERT PLATE
• A special INSERT PLATES (M.S) has to be left in the beam for canopy, they can be considered as a part of reinforcement
• The use of insert plates can either be for any canopy structure further to be erected as finishing exact detail of which, was not given by client.
• For a rough idea, Insert plates are basically a steel plate with a anchor Of 20 mm or 16 mm dia bar attached with it
• A fabricating agency was called for this activity.
Second storey key plan
Insert plate detail
Insert plate details• First of all 16mm plate were indented for the work, mild steel plate comes in
dimension of 1250 x 2550 mm , 6 such plates were bought.• These plates are issued to the fabricator. Fabricator first of all cuts the plates to
required sizes i.e. 1200 x 600mm 16 plates and 1450 x 600 – 2 plates, with the help of gas cutter.
• After these anchor bars cut and bend as per specification are welded to the mild steel plates, since 8mm weld size is given, welder gives two run of weld, 8mm used is not ensured by any particular method they depends on skill of welder.
• After the insert plates are ready they are lifted by crane and brought to location, the outer beam top and bottom reinforcement are already laid, for insertion of plate the extra top bar of beam are not tied, the plate are inserted in position by anchor bars and after that extra top bars of beam are inserted.
• Insertion of plate needs extreme efforts near beam junction due to heavy reinforcement present.

Equipments-Rock Drilling Machine
• Rock Drilling machine• Rock drilling machine used is a pneumatic
machine capable of drilling 27-48mm diameter holes up to depth of 10 to 12 feet.
• Drill beat used here is a 2 feet drill and 48mm in diameter.
• It is connected with a 6 HP compressor, the drill machine is connected to the compressor with the help of flexible hose
Equipments-Rock Splitter
• Rock Splitter• Hydraulic rock concrete splitter is used to split
the rock.• It is develops very huge splitting force of 800T
when it put into the pre-drilled holes of rock.• The hydraulic rock splitter is most suitable
tool. It has following salient features
Procedure• Rock drillers is used and holes of 48mm diameter are drilled in the
rock.• Drill beat drill hole of 2 feet deep and 48mm diameter, after a hole
is drilled a splitter is inserted and the cracks develop in the rock.• Rock splitter splits rock and diagonal cracks are developed, it
cracks above 400mm of the hole.• So in case a one meter rock has to be drilled the same set of
activity is done twice.• Once the large crack are developed rock is removed manually by
inserting steel bars in cracks• The large rock is then chipped in to pieces with the elp of chipper.

Over view of other construction activity observed
• Surveying• Excavation• Footing in Rock• Sleeves in vertical member
Surveying• Surveyor at site uses mainly automatic level and total
station for all surveying purposes• The total plot area has been traversed with 7 station point
and reference for all the footings and column are made in total station
• After the slab is casted total station is installed on the slab by back sighting any two point and the refrence point for all the points of column are marked.
• Vertical level are tranfered with the help of automatic level. Vertical level are useful for maintaining the required floor height and other purposes.
Excavation
• Exacavation with Pocklain (Back hoe)• Rates where for how many hours the machine
works• Large mobile cranes of 50 tonne capacity were
called, for lifting pocklain
Footing in Rock• As discussed earlier some of the rocks were coming in the
way and complete footing was not sitting for this purpose rock drilling was used also now rock cannot be drilled such that full footing sits, in many cases ¾ footing was sitting
• So with the permission of consultant bars of column were drilled in the rock upto the approved length and grouted
• Bars were drilled upto the depth of 450 mm and grouted with the help of mungu chemical.
• Thus for such footing half of the footing was constructed and bars of the column were drilled in side the rock upto the approved depth.
Sleeves in Vertical Member• Numerous sleeves of varying diameter and level were to be
inserted in the water tank as well as in retaining wall. • It is important that sleeve is of mentioned diameter and at
required level• First of all the reinforcement of the wall or water tank are
tied and than later on the reinforcement of the wall is cut and the puddle flange is kept in the position
• Not horizontal bars are kept below the puddle flange and welded in position at required level also for suck section of wall conventional aluminum secondary falcas cannot be used for that falca of plywood and timber need to be used.
