a few boreholes to survey theories and computer Math the average depth of the pile stuffing. In fact due to the geological cross-section may be wrong other non-flat between the drill should not necessarily have to drill the right to a design depth.-In fact the designer defined location floor laying and floor when the drill is submerged into the strata deposit at least once to the diameter (1 d). To correctly identify this stops when drilling one sample for each bucket drill. Field supervisors have reached the required depth is 45 m compared to the bottom of the radio, record including photograph reporting material for each drill hole, then use a clean bucket to cleaned ground down in the bottom of the drill hole and move on to another phase.II. 4 reinforced pile construction II. technical requirements 4.1 General:-reinforced work are machined according to drawing. Contractors have to layout construction, snowman, master, bending, cutting and belt leak forced the steel cage as prescribed -reinforcement built in the play yard at public school, built into the cage, the greatest length of each cage depends on the ability to mount cranes and the length of the factory owner. Steel cage must have toughened steel reinforced core belt and beyond as calculated to ensure the twisted, distorted steel cage. The cage must be hung by hooks of steel rebar used crane, making the number of hangers to calculate enough to hook both the cage into the tube against the interim without losing the bottom of boreholes, or construct the cages bottom pads avoid the cage of steel sunk inclined as well to make sure the thickness of concrete layer on the bottom of the pile. protection tong-the usual reinforced core diameter core holder, like bending the rings placed throughout the home the distance from 2, 5 m-3 m with reinforced lien home by South Korea and the strapping at the request of the design. When transporting, crane mounting can be used inside steel cages temporary way to avoid distortion.-Centering steel cage with the statistics produced from the smooth steel welded on the core server Center piles, or by the members of the round ximang-sand, according to the principle of sliding wheels, fixed on two steel home using steel shaft, the width or the RADIUS statistics depends on the thickness of the layer of protection , thong is usually 5 cm. the amount of the inventory is sufficient to lower the main steel cage.-Connect the steel cages are mainly by the strapping, steel connection length as specified by the design. When the pile has a length greater than, the contractor must take measures to avoid seams reinforced steel cage drop when lowering the cage.-Ultrasonic tube (typically 60 mm diameter steel pipe) should be forced into the home bottom of reinforced chạt pipes are sealed and lowered the bottom of the pile, pipe connection by welding, there is closure ensure the sealed, avoid water leak clog pipes, cement when the installation needs to ensure Eastern mind, ultrasonic pipe length as indicated by the lack of a higher design usually set ground from thong leveled around pile from 10 cm to 20 cm, after pouring the concrete tong the tubes were filled with water and sealed to avoid the strange creatures fall into clogging the tube.-Ultrasonic tube attention is required as follows:1 tube diameter pile with 60 cm3 pipe pegs from 60 cm to be two4 tube for two larger piles
