PILING FOUNDATION Meeting 3 Study Program: S0673/Building Construction II Period: 2007

Bina Nusantara This foundation is especially used to shoulder heavy burden and crucible located hard geology in exceeding 7-30 meter under ground face. Piling used for high storey building and bridge. Energy that support it pursuant to pressure tip of which also can be combined with adhesion force of pillar sides. Piling Foundation 3

Bina Nusantara qc.A  end bearing qc= pressure of konus. (penetration resistance) kg/cm 2 A= Wide surface of pillar. TF= Total Friction O = Circle Materials Piling earn made from : Wood Reinforced concrete. Steel ( pipe or profile ) 4

Bina Nusantara Used wood type :  Iron wood ( Kalimantan )  Black wood ( Sulawesi )  Merbau wood ( Sumatera ) Is compared to concrete piling and steel, energy support limited, because : a. Its limited diameter ( Ø 20 cm ) b. Limited length. 5 Piling Wood Foundation

Bina Nusantara Wood before stake, commented beforehand with “ Tar” materials or wood of a kind with aim to to be more conserve wood. Wood pole foundation earn durability, come from all pillar under low ground water face. Wood pole foundation can be combined with : Couple stone foundation split. With reinforced concrete sloof. 6

Bina Nusantara This piling of length have to reach hard ground. Piling stake must be done pillar and carefully have to be vertical and its situation precisely at planned dot. If pillar which is oblique stake, hence can generate eccentricity and rise moment able to endanger construction. Stake to one pillar have to be finished till finish, may not be stopped for to be continued the day after. Piling Foundation Reinforced Concrete 11

Bina Nusantara Various piling size measure:  25 x 25 cm 2  30 x 30 cm 2  35 x 35 cm 2  40 x 40 cm 2  45 x 45 cm 2 Hammer appliance used depended from wide surface of pillar. Surface of pillar besides in form of its square, earn also circular, trilateral and hexagon. Square form more used, because making of its easier concrete mould than other form. 12

Bina Nusantara Piling reinforced concrete restating consist of fundamental bone and bone of spiral. Relation between column with piling through pile cap and piling irons released from back part / battered piling head, to be weared as bone stek. 13

Bina Nusantara Hard ground of its deepness not yet until 6.00 m of ground face. Its ground easy to drilling (not have the character of bog) Pillar foundation of Straus is reinforce concrete pile which in local formed. Surface size measure Ø 25 cm, 30 cm. Its restating consist of fundamental bone and spiral which is energy support it pursuant to pressure tip of and coherent energy. Straus Foundation 15

Bina Nusantara Pillar foundation of Straus each other attributing to link sloof. Pillar of Straus shouldering connected special column to through pile cap. Way of its Execution:  Ground drilled which level of as according to pillar of Straus reach hard geology.  Including bone framework which have been prepared, and exaggerated fundamental bone length to be weared as stek which step into pile cap.  If in hole there are water, hence have to be pumped former out. 16

Bina Nusantara  Including to inform against concrete and boxed so that tip of under wide, then inform against entered next reach side below/under pile cap or sloof.  Hereinafter work of pile cap. 17
