Pile into the hole, pile driver into the scene, according to the design of pile length, immersed into the depth of the rack to determine the height and length of the immersed tube (with paint on the tube section marked long pile), and assembly. Pile driver in place: according to the design pile position pile, pile driver to maintain the level, solid, adjust the sun and the vertical ground to ensure that the vertical deviation of not more than 1%. Start the motor, sink to the scheduled elevation, stop. In the process of sedimentation, a record should be made to observe the change of the excitation current and to note the change of the soil. Mix the mix according to the design mix, the mixture is concentrated by the mixing station. Slump should be 120 ~ 160mm, stirring time shall not be less than 2min.

To be submerged to the design elevation as soon as possible after the feeding, until the tube mixture with the steel pipe material mouth flush. Such as the amount of material is not enough to be in the process of extubation in the air to add feeding to ensure that the piles of pile height to meet the design requirements. Start the motor, immersed in situ to stay vibration 5 ~ 10S, and then edge vibration edge extubation, extubation speed is generally controlled at 1.0 ~ 1.2m / min, in case of mud or muddy soil, extubation speed may be appropriate to slow down Tube process does not allow anti-plug. When the pile pipe pulled out of the ground, confirmed that the pile reached the design height, the embedded pile cap steel, and then move the machine to continue the next pile construction, construction process to do the construction records. After a period of 28 days after the completion of the pile foundation, check whether the pile quality meets the design requirements.Road Repair Machines

Immersed tube: pile driver in place to be smooth, stable, adjust the vertical and vertical ground, to ensure that the vertical deviation of not more than 1%. Start the motor, began to sink, immersed in the process of attention to adjust the stability of the pile driver is strictly prohibited tilt and dislocation. Immersed in the process of construction records. Feeding: to be submerged to the design elevation should be as soon as possible after the feed, until the tube mixture with the steel pipe feeding mouth flush. If the amount of material is not enough, must be in the process of extubation in the air feeding, in order to ensure that the pile height to meet the design requirements. Mixing ratio should be strictly enforced design requirements, pile into the pile after the top of the floating slurry thickness is generally not more than 200mm. Mix the mixture to be uniform, stirring time shall not be less than 2min. Construction sequence: before the construction of the original surface and slope should be clear table processing, leveling the site, excavation of the first level, and then backfill compaction, rolling to the original surface, and then the construction of concrete pile, On the surface of 25cm, easy to construction pile cap, concrete concrete pile construction should start from the old slope foot, and then push out the slope pile to the roadbed to fill the pile after the elevation. Piling machine row by row. The spacing between adjacent two piles in construction shall not exceed the initial setting time of the mixture so as not to affect the strength of the mixture.
