Construction spoken of the "piling" is the production of pile foundation, pile foundation is piling pipe and pile caps are constructed deep foundation. (Sandpile foundation treatment, also can be seen as piling), divided into friction piles and piles according to the force.

Friction piles are the use of friction with the surrounding sediment to bear the weight of the upper building structure; bearing piles is to hit solid ground formations and to the upper building structure loads are transmitted through the pile on solid ground. the terminology "piling" means the use of an impact pile hammer to overcome the resistance of the pile of soil, the pile sink to a predetermined depth or reaches the stratum. 

Piling ready

Choose a pile hammer, you must fully consider the pile shape, size, weight, buried length, structure and soil, weather and other conditions, and mastery of the characteristics of a variety of hammers. Pile hammer tamping energy must overcome pile penetration resistance, including resistance to overcome the pile tip, pile lateral friction and pile rebound energy generated losses. If the pile hammer energy can not meet the above requirements, it will cause the local buckling head of the pile, the pile is difficult to design elevation. Pile frame setup, installation, and ready-to-work have a great impact on the efficiency of the piling. Pile frame selection D-308S-type crawler-type pile frame, its biggest feature is mobile and flexible, easy to use, run institutions track, on the road requirements are relatively low. Within the construction area according to the piling and foundation geometry of geological conditions, a reasonable choice of piling order to take preventive measures against the surrounding buildings. According to construction drawings pile testing. Pile generally needs to design with two fulcra, its location must meet the requirements of lifting points. Pile stockpiling needs to use a padded (wooden mat). Pile lifting transportation should be free from vibration, and shock.

Piling process

Pile into the pile angle correction process is more difficult, so in place should be properly stowed. Section pile into the ground, we should try to maintain its position in the right direction. Began to gently lay seriously checked and any deviation should be promptly corrected, if necessary, to remove heavy fighting. Checking the verticality of the pile can be the vertical angle, i.e. with two directions (each 90 °) of the theodolite to the guide frame is vertical. The pile guides through the rotation, and sliding, and remains to be adjusted. Theodolite should be set in place without piling effect and is frequently leveled so that it remains vertical. Because the surface stratum is relatively soft, beginning to sink a large amount of playing time may be advised to take a low mentioning hammer, lightly lay, with the deepening pile, settling velocity slows down, increasing height from the hammer. Throughout the piling process, make the pile hammer, pile caps, and pile try to keep on the same axis. Necessary, will pile hammer and pile frame guides the direction of the pile direction by adjustments.

Try not to pay attention to the pile by the eccentric hammer to avoid pipe bending attorney. Piling more difficult to sink, to check whether the tilt hammer eccentricity, in particular, to check the pile mat pile cap is appropriate. If appropriate, the need to replace or supplement the cushion.

Each pile should be a continuous one-kick, do not interrupt, so difficult to continue to lay.
