2 Construction Introduction

2.1 The main method for construction

Every piece of steel casing will be fabricated in the factory as a whole part Spiral

Pipe. So there is no welding connection in the job site. After checked in the factory,

all the steel casings are delivered to the Tayan storage yard by barge.

In the job site, the steel casing will be drived down to designed position and

elevation by using a 80t barge crane with vibrating hammer. The crane is used to erect

the steel casing and lift the vibrating hammer. Vibrating hammer is used to drive the

steel casing. One guide frame will be used to ensure the verticality comply with

2


specified allowable tolerance that is not more than 2%.

3 Construction Method of Steel Casing

3.1 The reinforcement design of steel casing

In order to avoid deformation, stiffening rings were welded around the steel

casing. On the top and bottom ends, a 0.5m long stiffening ring is added for dia.

1200mm steel casing, and 0.8m long stiffening ring is added for dia. 1700mm steel

casing. Some 100mm long stiffening rings are added in middle of steel casing, the

detailed design drawing is shown as the attachment document: Shop Drawing of

Steel Casing.

3.2 Steel Casing Fabrication and Delivery

Steel casing will be fabricated in the factory in Jakarta. All steel casing is rolled

and welded by automatic steel pipe rolling machine. A very good guarantee can be

obtained for the quality of steel casing. Every piece of steel casing is processed as a

whole part spiral pipe. It means there will be no welding connection job in the

construction site.

Fig. 3.2-1 Steel Casing Fabrication

After the quality and the quantity of steel casing is checked to complying with

the specification request, the product can be delivered. The steel casing is transport to

port by long truck firstly, and then delivered form Jakarta Port to Tayan inland

5


temporary jetty by barge. In steel casing stack progress, the focus is to prevent

deformation. For diameter 1200mm steel casing, the maximum stack layer is 3 layer;

for diameter 1700mm steel casing, it is only allowed in 2 layer. Measures to prevent

rolling during sea shipping, should be adopted. The demand for stack in the Tayan

storage yard is accordance to the standart handling steel casing material.

3.4.2 Construction Method of Driving Steel Casing in Bridge2

⑴Move and anchor the barge crane

For the barge crane, there are 4 pieces of anchor windlass installed in 4 corner

of barge. Every anchor windlass has 100m wire rope at least, and 1 heavy steel anchor

is fixed on the other end of wire rope. The anchor offer anchor force to the barge

crane, the windlass can adjust the position of barge crane without the tug boat, by

pulling and release the wire rope.

In the beginning of every pier, one tug boat move barge crane to the piling

location of first row of steel casing. The other tug boat takes the anchor to the anchor

position and drops it into the river. After 4 pieces of anchor are drop to the designed

point, the 4 windlass pull the wire rope to make all the wire rope is in force state. Now

the barge can be fixed in position by 4 anchors.

10


Fig.3.4.2-1: Barge anchoring

⑵Install guide frame

In order to ensure the accuracy for coordinate and verticality of steel casing,

aguide frame will be adopted. The inner diameter of guide frame is 3 cm larger than

the outer diameter of steel casing, and the height of guide frame is 3.2 m. Guide frame

structure is designed as follow:

11


Fig.3.4.2-2.Guiding Frame

Before vibrating the permanent steel casing, in order to offer a stable fixed

platform for installing the guiding frame, a small temporary platform will be

established firstly.This temporary guide frame platform is composed of 4 steel pipes

and 2 main beams as following drawing.

Fig. 3.4.2-3 The design of guiding frame platform

The guide frame will be installed on it. If the guiding frame is checked in correct

coordinate and vertical direction, the guide frame can limit the steel casing in fixed

12


point and lead the steel casing to slide along vertical direction.

Fig. 3.4.2-4 Vibrate steel casing by guiding frame platform

After the first row of steel casings completed, demolish the temporary guide

frame platform and establish the corresponding drilling platform on the first row of

steel casing. Then the guide frame will be installed in cantilever method on the top of

drilling platform to vibrate steel casing. Furthermore all the other steel casings will be

vibrated in this method.

Fig.3.4.2-5 vibrate steel casing by cantilever method

⑶ Survey and Coordinate Control of Bridge 2

13


Two total stations will be used to suvery the steel casing at the same time. Every

steel casing will be setting out by two total stations.The total station lacation should

be choosed in the river bank to survey different pier’s steel casing. The two

surveying sight should be an angle of approximately 90 degrees.

Survey the guide frame control position firstly, adjust the barge position in

according with the calculated deviation until complying with the allowable tolerance

that is not more than 7,5 cm. Fix the location by 4 anchors and keep the stability of

the barge in the help of tug boat.

Fig.3.4.2-5 total station location for pilling

⑷ Erect steel casing

The lengthiest of steel casing is 21.5m, it will be erected by barge crane and put

into guiding frame.

The steel casing is slided in the guide frame slowly until the bottom begin to

insert the riverbed. Move the crane boom to adjusted the steel casing verticality until

the surveyor confirm the verticality is correct, and then continue to sink the steel

casing into the riverbed untill stop. Check the verticality again, if no problem, loose

the lifting wire rope and continre to next procedure, or lifte up the steel casing out of

the river bed again to adjust the viticalrity.

14


Fig.3.4.2-6 place the steel casing into the guiding frame

⑸Vibrat steel casing

Keep the stability of barge, after the coordinate and verticality is checked. The

crane lifte the vibrating hammer moving to the top of steel casing slowly, which

stands in the riverbed. Insert hammer clamp into the steel casing and fix the

hydraulic clamp firmly. Any impact and force should be avoided applied to steel pipe

to influnce the viticality. Afterward the crane lower down the hammer slowly, to give

hammper’s death weigth to the top of steel casing, making the steel casing sinking

down slowing. During the procedure, the crane boom should adjust and keep the

viticality continously until the steel casing stoping sinking again. If the steel casing

become inclined out of allowable tolerance, the steel casing should be lifted up of

riverbed to sink again.

15


Fig.3.4.2-7 vibrate the steel casing in guiding frame (1)

Turn on the generator to provide the power to the vibrating hammer. Switch on

the vibrating hammper only two second, check the verticality after every stop and

then continue to switch on in very short time again.

Fig.3.4.2-8 vibrate steel casing in guiding frame (2)

When it is obvious that the steel casing is vibrated into the riverbed deep enough

to keep the verticality without change, remove the guiding frame and then switch on

the hammper with full power continuously until the steel casing can not be vibrated

16


down anymore or stop in the design elevation.

Fig.3.4.2-9 vibrate steel casing without guiding frame

After one steel casing was finished, the surveyor check the coordinate and

elevation, if it is low than the allowable tolerance, move the barge and continue to

vibrate the next steel casing.

Fig.3.4.2-10 The installed steel casing of one pier

17


⑹ weld the bracing

After every steel casing is vibracted, weld the bracing immediately, in order to

form as a whole. The section steel or steel pipe will be used as the bracing. Any job

will not be allowed before bracing welded. The bracing should be weld as follow.

5 Quality Assurance

① It need check the guiding frame and equipment, make sure they are in good

condition.

② When steel casing was driving, the surveyer need check the position and

verticality as soon as possible.

③ When the position and vertical is adjust to the design value , the steel casing

will down slowly by crawler crane. When the bottom was on the river bed, the steel

casing is sinking by itself weight, and then the steel casing have enough

stability，move the guiding frame, and then continue to driving by hammer. When it

is driving, make sure the hammer and axis of steel casing on same vertical line.

6 Safety Assurance

① It need check the equipment before start to hoist, and make sure they are in

good condition.

25


② The crawler crane need put down the boom onto the brackets when it is

moving; the driver need cooperate with the director, and the director should have

correct directing posture .

③ Before hoisting, the lifting eyes should be checked, make sure it is intact.

④ The workers should wear a helmet and life jackets. When the storm is

happened ,it should strengthen the machinery and equipment, and take personnel and

vessels to the safety area. In case of gale of more than Grade 6 (wind speed is 13.8

m/s) (including Grade6), working of driving steel casing is not allowed.

⑤ The safety engineer should be responsible for safety in the working areas.
