Piling is one of the type of foundation used for high-rise building or tower building, the shape of pile can be a cylinder or triangle denggan length of pole 10 m to 30 m, if the depth of the pile exceeds one pile it can be done grafting. various methods of work can be used as a way of pile pile foundation is like using diesel hammer equipment with the sequence of work steps as follows
How to install pile foundation
-Testing the ground on the foundation plan for the soil type and hard layer depth.
-Calculating the structure of the pile foundation so that it can be determined the need of pile size, material specification and pile depth so that it is strong to withstand the load of the building which is channeled to the calculation point.
-Production of piles can be done dipabrik with specifications according to the calculation then dkirim to the project location using a large truck vehicle.
-Pile lift removal can use tower crane or crane car with the position of lift point according to calculation so that there is no broken in appointment.
-The surveyor made a field measurement to determine the points according to the drawing and then set up the theodolite to check the erection of the erection, the pile raised perpendicularly then the position of the end diesel hammer increased and the paal cap inserted on the head of the pile.
-The erection of the erection position is controlled using 2 teodilitated pieces mounted in two directions to ensure the position of the upright pile and control every 2 m, the erection is carried out to the planned depth elevation.
-The remaining piles above the plan elevation are stripped of concrete so that the remaining reinforcing steel will be used as cuttings to be associated with a pile cap on the building or abutment on the bridge construction.
Possible errors in the design of the pile foundation may lie in the use of the material under the calculation specification so that the foundation is not strong, otherwise errors in the appointment that are not at the safe point may cause a fracture, the slope of the erection can also occur due to poorly controlled enforcement thus reducing depth and strength of different foundations of planning.
